Metacarpal fractures represent up to 33% of all hand fractures; of which the majority can be treated non-operatively. Previous research has shown excellent putcomes with non-operative treatment yet surgical stabilisation is recommended to avoid malrotation and symptomatic shortening. It is unknown whether operative is superior to non-operative treatment in oblique or spiral metacarpal shaft fractures. The aim of the study was to compare non-operative treatment of mobilisation with open surgical stabilisation. 42 adults (≥ 18 years) with a single displaced oblique or spiral metacarpal shaft fractures were randomly assigned in a 1:1 pattern to either non-operative treatment with free mobilisation or operative treatment with open reduction and fixation with lag screws in a prospective study. The primary outcome measure was grip-strength in the injured hand in comparison to the uninjured hand at 1-year follow-up. The Disabilities of the Arm, Shoulder and Hand Score, ranges of motion, metacarpal shortening, complications, time off work, patient satisfaction and costs were secondary outcomes. All 42 patients attended final follow-up after 1 year. The mean grip strength in the non-operative group was 104% (range 73–250%) of the contralateral hand and 96% (range 58–121%) in the operatively treated patients. Mean metacarpal shortening was 5.0 (range 0–9) mm in the non-operative group and 0.6 (range 0–7) mm in the operative group. There were five minor complications and three revision operations, all in the operative group. The costs for non-operative treatment were estimated at 1,347 USD compared to 3,834USD for operative treatment; sick leave was significantly longer in the operative group (35 days, range 0–147) than in the non-operative group (12 days, range 0–62) (p=0.008). When treated with immediate free mobilization single, patients with displaced spiral or oblique metacarpal shaft fractures have outcomes that are comparable to those after operative treatment, despite some metacarpal shortening. Complication rates, costs and sick leave are higher with operative treatment. Early mobilisation of spiral or long oblique single metacarpal fractures is the preferred treatment.

Abstract. Objective. Meta-analysis of clinical trials highlights that non-operative management of degenerative knee meniscal tears is as effective as surgical management. Surgical guidelines though support arthroscopic partial meniscectomy which remains common in NHS practice. Physiotherapists are playing an increasing role in triage of such patients though it is unclear how this influences clinical management and patient outcomes. Methods. A 1-year cohort (July 2019–June 2020) of patients presenting with MRI confirmed degenerative meniscal tears to a regional orthopaedic referral centre (3× ESP physiotherapists) was identified. Initial clinical management was obtained from medical records alongside subsequent secondary care management and routinely collected outcome scores in the following 2-years. Management options included referral for surgery, conservative (steroid injection and rehabilitation), and no active treatment. Outcome scores collected at 1- and 2-years included the Forgotten Joint Score-12 (FJS-12) questionnaire and 0–10 numerical rating scales for worst and average pain. Treatment allocation is presented as absolute and proportional figures. Change in outcomes across the cohort was evaluated with repeated measures ANOVA, with Bonferroni correction for multiple testing, and post-hoc Tukey pair-wise comparisons. As treatment decision is discrete, no direct contrast is made between outcomes of differing interventions but additional explorative outcome change over time evaluated by group. Significance was accepted at p=0.05 and effect size as per Cohen's values. Results. 81 patients, 50 (61.7%) male, mean age 46.5 years (SD13.13) presented in the study timeframe. 32 (40.3%) received conservative management and 49 (59.7%) were listed for surgery. Six (18.8%) of the 32 underwent subsequent surgery and nine of the 49 (18.4%) patients switched from planned surgery to receiving non-operative care. Two post-operative complications were noted, one cerebrovascular accident and one deep vein thrombosis. The cohort improved over the course of 2-years in all outcome measures with improved mean FJS-12 (34.36 points), mean worst pain (3.74 points) average pain (2.42 points) scores. Overall change (all patients) was statistically significant for all outcomes (p<0.001), with sequential year-on-year change also significant (p<0.001). Effect size of these changes were large with all Cohen-d values over 1. Controlling for age and BMI, males reported superior change in FJS-12 (p=0.04) but worse pain outcomes (p<0.03). Further explorative analysis highlighted positive outcomes across all surgical, conservative and no active treatment groups (p<0.05). The 15 (18%) patients that switched between surgical and non-surgical management also reported positive outcome scores (p<0.05). Conclusion(s). In a regional specialist physiotherapy-led soft tissue knee clinic around 60% of degenerative meniscal tears assessed were referred for surgery. Over 2-years, surgical, non-operative and no treatment management approaches in this cohort all resulted in clinical improvement suggesting that no single strategy is effective in directly treating the meniscal pathology, and that perhaps none do. Clinical intervention rather is directed at individual symptom management based on clinical preferences. Declaration of Interest.

Plantar fasciitis (PF) is one of the widespread conditions causing hindfoot pain. The most common presenting symptoms are functional limitation and pain (first step and activity) on plantar surface of the foot. The non-operative treatments provide complete resolution of pain in 90% of patients, but functional limitation still remains as a risk factor for recurrency of PF. Although the number of non-operative treatment options showing efficacy on pain and functional limitation are excessive, the evidences are limited for functional limitation. Additionally, Mulligan mobilization with movement (MMWM) in Chronic Plantar Fasciitis has been poorly studied in the literature. According to these findings, the study was aimed to determine effectiveness of Mulligan mobilization with movement on Chronic Plantar Fasciitis. A total of 25 patients (40 feet) with chronic PF were included in the study. The patients were randomly divided into Mulligan concept rehabilitation group (PF-M, n=20 feet) and Home Rehabilitation group (PF-H, n=20 feet). (MMWM), Foot and ankle exercises program were applied to PF-M, twice a week totally 8 week (16 sessions) and foot- ankle exercises as a home program were given for PF-H, 8 weeks. The range of motion (ROM) for dorsiflexion and plantar flexion was measured by using a manual goniometer. Pain, disability and activity restriction were assessed by Foot Function Index (FFI) . The first step morning pain was evaluated by Visual Analogue Scale (VAS) and Kinesiophobia was also reported by using Tampa Scale (TSK). Patients were evaluated at baseline and 8 weeks. FFI, VAS, TSK, ROM values improved in all groups (intragroup variability) at 8th week (P < .05). The other result indicated that ROM values for DF and PF and TSK scores in PF-M had more significant improvement than PF-H (p<.05). To the best of our knowledge this is the first randomised controlled trial for investigating Mulligan Concept efficiancy on chronic PF. Both Mulligan mobilization with movement (MMWM) and exercise protocols are effective for chronic PF. Furthermore, The Mulligan concept seems more effective treatment option in reducing kinesiophobia and improving functional capacity

Abstract. Objectives. The outcomes from patella fracture have remained dissatisfactory despite advances in treatment, especially from operative fixation1. Frequently, reoperation is required following open reduction and internal fixation (ORIF) of the patella due to prominent hardware since the standard technique for patella ORIF is tension band wiring (TBW) which inevitably leaves a bulky knot and irritates soft tissue given the patella's superficial position2. We performed a systematic review to determine the optimal treatment of patella fractures in the poor host. Methods. Three databases (EMBASE/Medline, ProQuest and PubMed) and one register (Cochrane CENTRAL) were searched. 476 records were identified and duplicates removed. 88 records progressed to abstract screening and 73 were excluded. Following review of complete references, 8 studies were deemed eligible. Results. Complication rates were shown to be high in our systematic review. Over one-fifth of patients require re-operation, predominantly for removal of symptomatic for failed hardware. Average infection rate was 11.95% which is higher than rates reported in the literature for better hosts. Nevertheless, reported mortality was low at 0.8% and thromboembolic events only occurred in 2% of patients. Average range of movement achieved following operative fixation was approximately 124 degrees. Upon further literature review, novel non-operative treatment options have shown acceptable results in low-demand patients, including abandoning weight-bearing restrictions altogether and non-operatively treating patients with fracture gaps greater than 1cm. Regarding operative management, suture/cable TBW has been investigated as a viable option with good results in recent years since the materials used show comparable biomechanics to stainless steel. Additionally, ORIF with locking plates have shown favourable results and have enabled aggressive post-operative rehabilitation protocols. TBW with metallic implants has shown higher complication rates, especially for anterior knee pain, reoperation and poor functional outcomes. Conclusion. There is sparse literature regarding patella fracture in the poor host. Nevertheless, it is clear that ORIF produces better outcomes than conservative treatment but the optimal technique for patella ORIF remains unclear. TBW with metallic implants should not remain the standard technique for ORIF; low-profile plates of suture TBW are more attractive solutions. Non-operative treatment may be considered for low-demand individuals however any form of patellectomy should be avoided if possible. Declaration of Interest.

The British Orthopedic Association recommends that patients referred to fracture clinic are reviewed within 72 hours. With the increase in referrals and limited clinic capacity it is becoming increasingly difficult to see every referral with in a 72 hour time frame. Some patients are waiting 2 weeks or more before they can be seen in a fracture clinic. With the aim of improving care by seeking to meet BOAST 7 target, waiting times for fracture clinic appointments at the Homerton University Hospital were audited prospectively against this national guideline, before virtual fracture clinic was implemented and 6 weeks after the implementation of virtual fracture clinic at our hospital. Virtual fracture clinic is where an Orthopedic consultant reviews a patients x-rays and A&E documentation and decides if that patients needs to be seen in a face to face fracture clinic to discuss operative vs. non-operative management of their injury or if a treatment plan can be delivered without the patient having to come back to hospital. The study was conducted as a prospective closed-loop audit in which the second cycle took place after the implementation of the new virtual fracture clinic service. The first cycle showed a non-compliant waiting time with only 18% of patients being seen within 72 hours. Following the implementation of virtual fracture clinic, 84% of all patients were reviewed within 72 hours. Virtual fracture clinic delivered a significant reduction in waiting times. Virtual fracture clinic has only just been implemented at the Homerton University Hospital and hopefully at the next audit we will be 100% compliant with the BOA BOAST 7 Guideline. We would recommend that virtual fracture clinics being rolled out in Orthopedic departments in all hospitals which have Orthopedic services

Knee osteoarthritis is a common, debilitating condition. Intra articular corticosteroid injections are a commonly used non-operative treatment strategy. Intra articular hip injection with Ketorolac (an NSAID) has proven to be as efficacious as corticosteroids. No prior study compares the efficacy of Ketorolac relative to corticosteroids for relief of discomfort in knee osteoarthritis. The study design was a single centre double blinded RCT. Severity of osteoarthritic changes were graded on plain film weightbearing radiographs using the Kellgren and Lawrence system. Injection was with either 30mg Ketorolac or 40mg Methylprednisolone, given by intra-articular injection, in a syringe with 5mls 0.5% Marcaine. Pre-injection clinical outcomes were assessed using the Numerical Pain Score (NPS), WOMAC, and Oxford knee scores. Patients' NPS scores were assessed at Day 1 and Day 14 post-injection. An assessment of all clinical outcomes took place in clinic at six weeks. There were 72 participants (83 knees) in the study. No patients were lost to follow-up. Mean age was 62.66 years (Range 29–85). 42 knees received a corticosteroid injection, 41 a NSAID injection. Mean Kellgren and Lawrence score was 3.1. There was no significant difference in pre-injection clinical scores in either group. There was a significant improvement of NPS on Day 1 and 14 in both injection groups(p<0.05). These improved pain scores were sustained at 6 weeks in both groups. WOMAC and Oxford Knee Scores showed a statistically significant improvement in the corticosteroid group. WOMAC scores showed significant improvement in the NSAID group, however these improvements didn't achieve statistical significance using the Oxford Knee Score. Corticosteroid or NSAID injectate are a safe and effective non-operative treatment strategy in the patient with knee osteoarthritis. Ketorolac appears to provide effective medium-term improvement of pain and clinical scores. Further follow-up is recommended to investigate if this trend in sustained

The aim of this study was to evaluate the time of return to play of elite basketball and voleyball players (both grouped together as jumper) with Haglund deformity after surgical resection of the prominence in the postero-superolateral aspect of the calcaneum. Haglund deformity is a prominence in the postero superolateral aspect of the calcaneum, causing a painful bursitis, which may be difficult to treat by non-operative techniques. In this study, we evaluated the duration that is needed to reach a level that a player perform regularly in a competition. This study consists of players operated by the same surgeon with same technique from 2011 to 2019. Twenty eight feet of 22 patients underwent resection of Haglund deformity with lateral approach and the outcome was analysed using AOFAS Ankle-Hind Foot Scale for hindfoot and time to restart a full range regular training was reported. All players received one dose (5–6 cc) platelet rich fibrin to attachement site of Achilles tendon peroperatively just after decompression of prominence. The mean AOFAS score at the follow up was 90/100, at the end of first year and the majority of players returned to play at 4th to 8th month of follow-up. Only two players with deformity of three feet could start to perform after one year. We conclude that minimal invasive approach ostectomy is an effective treatment for players suffering from Haglund deformity and the results were from good to excellent. However, the player should be well informed that the recovery and returning to play can take a longer time than they expect

Introduction. Lateral epicondylitis, also known as “tennis elbow,” is a degenerative disorder of the common extensor origin of the lateral humeral epicondyle. The mainstay of treatment is non-operative and includes physiotherapy, activity modification, bracing, nonsteroidal anti-inflammatory drugs, and injections. There is a subgroup of patients however who do not respond to non-operative measures and require operative intervention. Methods. We conducted a retrospective review of prospectively collected data to assess whether the introduction of PRP injections for lateral epicondylitis led to a reduction in patients subsequently undergoing surgical release. Results. Prior to the introduction of PRP injections, a mean of 12.75 patients a year underwent arthroscopic release for tennis elbow. Since PRP introduction this reduced to a mean of 4.25 patients a year. Using a Pearsons chi squared test this is a significant fall in the number of releases required, P<0.001. This significant reduction in patients requiring surgery since PRP introduction leads to an absolute risk reduction of 0.773 and number needed to treat on “as-treated” basis of only 1.3. Conclusion. In conclusion we consider PRP injection, for intractable lateral epicondylitis of the elbow, not only a safe but also very effective tool in reducing symptoms and have shown it has reduced the need for surgical intervention in this difficult cohort of patients

Ponseti method has become the most common and validated initial non-operative and/or minimally invasive treatment modality of idiopathic clubfoot regardless of the severity of the deformity worldwide. Despite hundreds of publications in the literature favoring Ponseti method, the data about secondary procedures performed in the follow-up period of clubfoot and their incidence remains sparse and given as small details in the articles. The objective of this study was to analyse our incidence of secondary procedures performed in the midterm followup period of idiopathic clubfoot patients treated with Ponseti method and review of the relevant literature. For this purpose 86 feet of 60 patients with idiopathic clubfoot who were treated with original Ponseti method were enrolled in this retrospective case control study. Unilateral ankle foot orthosis (AFO) was used rather than standart bar-connected foot abduction orthosis varying from 12 months to 25 months in the follow-up period and 74 of 86 (86%) feet required percutaneous achilles tenotomy. The average age of initial cast treatment was 12.64 days (range 1 to 102 days). The mean follow-up time was 71 months (range 19 to 153 months). Thirty seven feet of 24 patients recieved secondary procedures (43%) consisting of; supramalleolary derotational osteotomy (SMDO) (1 patient/2 feet), complete subtalar release (3 patients/5 feet), medial opening lateral closing osteotomy (double osteotomy) (2 patients/3 feet), double osteotomy with transfer of tibialis anterior tendon (TTAT) (2 patients/3 feet), partial subtalar release (PSTR) (3 patients/5 feet), PSTR with SDO (1 patient/1 foot), posterior release (PR) with repeated achillotomy (1 patient/2 feet), TTAT (6 patients/10 feet), TTAT with PR (2 patients/2 feet), TTAT with Vulpius procedure (1 patient/1 foot) and TTAT with SMDO (2 patients/3 feet) respectively. The amount of percutaneous achilles tenotomy (86%) in our study correlated with the literature which ranged from 80 to 90 %. The transfer of tibialis anterior tendon continued to be the most performed secondary procedure both in our study (51%) and in the literature, but the amount of total secondary procedures in our study (43%) was determined to be higher than the literature data varying from 7 to 27 percent which may be due to unilateral AFO application after Ponseti method for idiopathic clubfoot deformity in our study

Objectives. To explore whether orthopaedic surgeons have adopted the Proximal Fracture of the Humerus: Evaluation by Randomisation (PROFHER) trial results routinely into clinical practice. Methods. A questionnaire was piloted with six orthopaedic surgeons using a ‘think aloud’ process. The final questionnaire contained 29 items and was distributed online to surgeon members of the British Orthopaedic Association and British Elbow and Shoulder Society. Descriptive statistics summarised the sample characteristics and fracture treatment of respondents overall, and grouped them by whether they changed practice based on PROFHER trial findings. Free-text responses were analysed qualitatively for emerging themes using Framework Analysis principles. Results. There were complete responses from 265 orthopaedic and trauma surgeons who treat patients with proximal humeral fractures. Around half (137) had changed practice to various extents because of PROFHER, by operating on fewer PROFHER-eligible fractures. A third (43) of the 128 respondents who had not changed practice were already managing patients non-operatively. Those who changed practice were more likely to be younger, work in a trauma unit rather than a major trauma centre, be specialist shoulder surgeons and treat fewer PROFHER-eligible fractures surgically. This group gave higher scores when assessing validity and applicability of PROFHER. In contrast, a quarter of the non-changers were critical, sometimes emphatically, of PROFHER. The strongest theme that emerged overall was the endorsement of evidence-based practice. Conclusion. PROFHER has had an impact on surgeons’ clinical practice, both through changing it, and through underpinning existing non-operative practice. Although some respondents expressed reservations about the trial, evidence from such trials was found to be the most important influence on surgeons’ decisions to change practice.

This protocol describes a pragmatic multicentre randomised controlled trial (RCT) to assess the clinical and cost effectiveness of arthroscopic and open surgery in the management of rotator cuff tears. This trial began in 2007 and was modified in 2010, with the removal of a non-operative arm due to high rates of early crossover to surgery. . Cite this article: Bone Joint Res 2014;3:155–60

Introduction. Osteonecrosis of the knee encompasses three conditions; spontaneous osteonecrosis of the knee, secondary osteonecrosis (ON) and post-arthroscopic ON. Early stage lesions can be managed by non-operative measures that include protected weight-bearing and analgesia. The aim of this study was to report the experience of the authors in managing early stages of knee ON by analysing the functional outcome and need for surgical intervention. Methods. All patients treated for osteonecrosis of the knee between 1st August 2001 and 1st April 2014 were prospectively collected. Treatment consisted of touch-down weight bearing for four to six weeks. The cases were retrospectively reviewed. MR imaging was evaluated for the stage of disease according to Koshino's Classification system, the condyles involved and the time taken for resolution. Tegner Activity Scale, VAS pain, Lysholm, WOMAC and IKDC scores were recorded at presentation and final follow up. Results. 51 cases were treated for knee ON at our centre; 40 cases of SONK, seven secondary ON and four post-arthroscopic ON. Of the seven cases of secondary osteonecrosis; 5 were secondary to self-reported high ethanol intake and two secondary to corticosteroid treatment. The mean age of the group was 56.9 years and 68.7% were male. The medial femoral condyle was the most commonly affected (54.9%). 86% reported resolution of clinical symptoms and a statistically significant improvement was reported in all functional outcome measures. Four patients required total knee arthroplasty; three in the post-arthroscopic group within 15 months and one following ON secondary to corticosteroids performed at 5 months. Conclusion. Early stage spontaneous osteonecrosis of the knee can be managed successfully without surgery if diagnosed early. Although secondary and post-arthroscopic ON seem to be more resistant. Larger studies are required to confirm or refute this. Level of Evidence. IV – a case series. Conflict of Interests.

Introduction. The management of adolescent hallux valgus (AHV) remains controversial, with reservations about both conservative and surgical treatments. Non-operative management has a limited role in preventing progression. Surgical correction of AHV has, amongst other concerns, been associated with a high prevalence of recurrence of deformity after surgery. We conducted a systematic review to assess clinical and radiological outcomes following surgery for AHV. Methods & Materials. A comprehensive literature search was performed in the Cochrane Library, CINAHL, EMBASE, Google Scholar, and Pubmed. The study was performed in accordance with the recommendations of the PRISMA guidelines. Demographic data, radiographic parameters, and results of validated clinical scoring system were analysed. Results. Nine contemporary studies reporting on 201 osteotomies in 140 patients were included. The female to male ratio was 10:1. Mean age at operation was 14.5 years (10.5–22). Mean follow-up was 41.6 months (12–134). The mean post-operative AOFAS score was 85.8 (sd ±7.38). The mean AOFAS patient satisfaction showed that 86% (sd ± 11.27) of patients satisfied or very satisfied with their outcome. On the DuPont BRS, 90% rated their outcome as good or excellent. There was a statistically significant improvement in the IMA (p=0.0003), HVA (p<0.0001), and DMAA (p=0.019). The main complication was persistent pain (12%); others included infection (2%), scar hypersensitivity (4.5%), and non-union, metatarsalgia, and CRPS (each at 0.5%), and no reports of metatarsal head AVN. Conclusion. Based on the most current published evidence, surgery for AHV shows excellent clinical and radiological outcomes, with high patient satisfaction. The rates of recurrence and other complications are lower than the historically reported figures. There is, however, a need for high level, multi-centre collaborative studies with prospective data to establish the long-term outcomes and optimal surgical procedure(s)

Background. Avulsion fractures of the base of the fifth metatarsal are some of the commonest foot injuries. The robust scientific evidence on the optimal non-operative treatment of these fractures is scant. We designed and conducted a prospective randomised non-inferiority controlled trial of symptomatic treatment versus cast immobilisation with the null hypothesis that cast immobilisation gave substantial benefit over the symptomatic treatment in terms of patient reported outcome measures(PROMs). The alternative hypothesis was that symptomatic treatment was not inferior. Methods. The primary outcome was the validated Visual Analogue Scale Foot and Ankle (VAS FA) score ranging from 0 to 100. The non-inferiority boundary was set at −10 points. Power sizing determined a minimum of 12 patients per group. Anticipating a significant loss to follow up, 60 patients of 16 years of age or older were randomised to receive either below knee walking cast immobilisation (n = 24) or symptomatic double- elasticated bandage (n = 36) for 4 weeks. Secondary outcome measures were EuroQol-5D, and American Orthopaedic Foot and Ankle Society scores. Data was analysed at the baseline, 4 weeks, 3 months and 6 months post injury by a clinician blinded to a treatment arm. Results. Symptomatic treatment proved to be non-inferior to cast immobilisation treatment in terms of VAS FA at baseline, 4 weeks and 6 months. Secondary outcomes showed similar comparative values between two treatment groups. Loss to follow up reached 43% at 6 months. The imputation of missing data was done and confirmed the non-inferiority of symptomatic treatment. Conclusions. Cast immobilisation does not appear to give benefits over symptomatic treatment of these injuries in terms of validated PROMs in adults. A significant loss to follow up should be expected with these fractures in medium term. Level of Evidence. II. Approval. NRES Yorkshire and the Humber reference: 11/YH/0297. Disclosure.

Distal radial fractures are amongst the most common trauma referrals, however controversy remains regarding their optimum management. We undertook a retrospective review of the management of distal radial fractures in our department. The prospectively maintained trauma database was used to identify patients admitted for operative management of a dorsally displaced distal radial fracture between June 2008 and June 2009. Only extra-articular or simple intra-articular fractures were included (AO classification A2/A3/C1/C2). Operation notes were reviewed to determine the method of fixation. Patients were contacted by post and asked to complete a functional outcome score - Disabilities of the Arm, Shoulder and Hand (DASH). A further 12 patients with similar fractures who had been managed conservatively were also asked to complete a DASH score to provide a comparison between operative and non-operative management. 98 patients were identified - 67 female, 31 male. Mean age was 51 years, range 15-85 years. All patients were at least 1 year post-op. 26 patients had manipulation under anaesthesia (MUA). 48 patients had MUA and K-wire fixation, which was supplemented with synthetic bone substitute in 16 cases. 3 patients had MUA and bone graft and 21 patients had open reduction and internal fixation (ORIF) with a volar plate. 34 correctly completed DASH scores were returned. A lower score equates to a better functional outcome. Mean DASH scores were: MUA 14.8; MUA+K-wire 13.1; ORIF 13.6; conservative 47.1. This data would indicate that patients with a significantly displaced distal radial fracture have a better functional outcome with operative management to improve the fracture alignment. However, all of the methods of fixation used resulted in similar functional outcomes at one year

Introduction. Osteonecrosis of the femoral head usually progresses to collapse in up to 70% to 80% of all cases. Previous studies have shown high failure rates with non-operative treatment, whereas, some surgical options including bone grafting, core decompression, osteotomy and arthroplasty have been recommended. Total hip arthroplasty and hemiarthroplasty, either cemented or cementless, are the last resort for improving the functional outcomes for the elderly. However, salvage of the femoral head in relatively young patients is widely advocated. Thus vascularized bone grafting has been recommended to salvage the collapsing femoral head. The purpose of this study was to evaluate the prognostic factors related to the outcome of the vascularized iliac bone grafting in the treatment of osteonecrosis of the femoral head. Methods. A retrospective case series review study is presented. Between April 1987 and April 2003, 47 patients (51 hips) in the authors' hospital underwent vascularized iliac bone grafting for the treatment of osteonecrosis of the femoral head. Three patients were lost to follow-up, thus, 44 patients (48 hips), 38 men and 4 women, were included in the study. All patients underwent operation by one experienced senior surgeon. Patients were grouped according to related risk factors, i.e., trauma, corticosteroid, alcohol, and an idiopathic group. A radiographic scale, the Ficat and Arlet classification system, was used for grading the osteonecrosis. We set the conversion to total hip arthroplasty as the end point for survival of vascularized iliac bone grafting in this study. Kaplan-Meier survivorship analysis was used to determine the significance with regard to the risk factors, age, Ficat and Arlet staging, gender, and side. Results. The Kaplan-Meier survivorship analysis showed that the 5-year overall rate of graft survival was 68.5% (95% confidence interval: 52.7% to 80.0%), 10-year overall rate of graft survival was 61.5% (95% confidence interval: 44.4% to 74.8%), and 61.5% (95% confidence interval: 44.4% to 74.8%) at 15 years. There was no significant difference between the groups regarding the prognostic factors of etiology, gender, side, and stage. The only significant parameter was the age that the patients older than 50 years had the worst 5-year survival rate of the femoral head (p<0.05). Conclusion. Vascularized bone grafting is a technically demanding procedure when compared to conventional core decompression or arthroplasty. However, this technique can preserve the femoral head from collapse and preclude the need for arthroplasty in young patients

Introduction. Subchondral insufficiency fracture of the femoral head (SIF) often occurs in osteoporotic elderly patients. Patients usually suffer from acute hip pain without any obvious antecedent trauma. Radiologically, a subchondral fracture is seen mainly in the superolateral portion of the femoral head. The T1-weighted magnetic resonance (MR) images show a low-intensity band in the subchondral area of the femoral head, which tends to be irregular, disconnected, and convex to the articular surface. This low-intensity band in SIF was histologically proven to correspond to the fracture line with associated repair tissue. Some cases of SIF resolve after conservative treatment, while others progress until collapse, thereby requiring surgical treatment. The prognosis of SIF remains unclear. This study investigated the risk factors that influence the prognosis of SIF based on the progression of the collapse. Methods. Between June 2002 and June 2008, seventeen patients diagnosed as SIF were included in this study. Sequential radiographs were evaluated for the presence of progression of the collapse. The clinical profiles, including the age, body mass index (BMI), follow-up period and Singh index were examined. The morphological characteristics of the low intensity band on the T1-weighted magnetic resonance images were also examined, with regard to the band length, band thickness and band length ratio; which is defined as a proportion of the band length to the weight-bearing portion of the femoral head. Results. Radiographically, a progression of the collapse was observed in 8 of 17 (47.1%) patients. The band length in patients with progression of the collapse (mean: 22.6 mm) was significantly larger than that in those without progression of the collapse (mean: 12.3 mm; P < 0.05). The band length ratio in patients with progression of the collapse (mean: 73.3 %) was also significantly higher than that in those without progression of the collapse (mean: 42.3 %; P < 0.01). No significant differences were seen in the other variables (the age, BMI, follow-up period, Singh index, and band thickness). Conclusion. One of the important differential diagnoses in determining SIF may include osteonecrosis. The shape of the low signal intensity band on the T1-weighted MR images is one of the characteristic findings in SIF: namely, it is generally irregular, serpiginous, convex to the articular surface, and often discontinuous. This low-intensity band is generally surrounded by bone marrow edema. Histopathologically the band in SIF represents the fracture line with associated repair tissue. On the other hand, in osteonecrosis, since the low-intensity band represents repair tissue, it is generally smooth and circumscribes all of the necrotic segments. In this study, the prognosis of SIF varied even though all the patients received similar non-operative treatments. If the prognosis for SIF can be predicted at the early stage, it would allow the design of optimal treatments in each patient. In this preliminary investigation, both the band length and band length ratio were demonstrated to be useful when selecting the optimal treatment for SIF

Introduction. The treatment of distal femoral fractures has undergone several changes during the past century, from non-operative techniques to more recently minimally-invasive internal fixation. The Less Invasive Stabilisation System (LISS) is an internal fixation plate that combines closed fixation of the distal femur using an anatomically pre-contoured plate with locked unicortical screws. Study aim. The purpose of this multicentre study was to review the use of the LISS plate in three regional centres with respect to fracture healing between different severities of fractures. Materials and methods. Patients treated with a LISS plate for a distal femoral fracture (AO/OTA Type 33A1 to 33C3) between 1st January 2004 and 1st June 2008 were recruited. Demographic data plus mechanism of injury, type of fracture, injury severity scores (ISS) and complications were documented. Subgroup statistical analysis using SPSS for Windows v. 17 was conducted to determine differences in the mean ISS, operating time, length of hospitalisation and ultimately, the time taken for union between groups of different fracture severities (Type 33A vs. Type 33C fractures). A P value of less than 0.05 was considered to be significant. Results. Across the 3 regional centres, a total of 88 patients presented with a distal femoral fracture, of which 44 were treated with a LISS plate. The mean age of the patients was 66.1 (range 9 - 99), with 15 males and 29 females. There were 14 Type 33A1, 13 Type 33A2, 6 Type 33A3, 1 Type 33B2, 1 Type 33C1, 5 Type 33C2 and 4 Type 33C3 fractures. Union was achieved within an average of 14.7 weeks (range 8 - 25) in 33 cases. Five cases exhibited non-union and were managed by a retrograde nail or another locking compression plate. Six cases developed delayed union. Subgroup analysis revealed that patients with Type 33C (n = 10) fractures presented with a significantly greater mean ISS score (12.7 vs. 10.0, p = 0.031), endured longer operating time (203.7 minutes vs. 125.8 minutes, p = 0.016) and spent longer in hospital compared to Type 33A (n = 33) fractures (35.3 days vs. 12.5 days, p = 0.004). However, no difference in the mean time for radiological union between the groups was observed (16.4 weeks vs. 13.6 weeks, p = 0.058). Discussion. We observed an overall success rate of 75% (33 out of 44 cases) as fractures reached radiological union within an average of 14.7 weeks. Interestingly, despite a greater mean ISS score and operating time among Type 33C fractures, the subgroup analysis confirmed that the LISS plate is a robust treatment option across all fracture severities, as this did not translate as longer time to union compared to Type 33A fractures. However, there were 5 cases of non-union and 6 cases of delayed union in our series. These may have arisen due to lack of precision in surgical technique, as we observed 8 cases of suboptimal implant positioning. Three cases involved distal screws lacking contact with the medial cortex of the femur. Overall, our data suggest a favourable outcome for the LISS plate in the treatment of distal femoral fractures

Objectives

Sustained intra-articular delivery of pharmacological agents is an attractive modality but requires use of a safe carrier that would not induce cartilage damage or fibrosis. Collagen scaffolds are widely available and could be used intra-articularly, but no investigation has looked at the safety of collagen scaffolds within synovial joints. The aim of this study was to determine the safety of collagen scaffold implantation in a validated in vivo animal model of knee arthrofibrosis.
