Aim:. To investigate the clinical outcomes of elbows with post-traumatic stiffness treated by open surgical release. Methods:. A retrospective review was completed on thirty-five consecutively managed patients who underwent an open elbow release for post-traumatic stiffness between 2007 and 2012. Pre-operative and post-operative range of motion (ROM), pain scores and functional outcomes were recorded. Results:. Mean follow-up was 31 months (6–84). The cohort consisted of 20 male and 15 female patients with an average age at time of surgery of 34 years (17–59). The interval from injury to time of release was 26 months (6–180). An improvement in mean ROM from 49° (0°–105°) to 102° (55°–150°) was obtained. The improvement in ROM in patients with pre-operative heterotopic bone was 61° compared to 45° in patients without heterotopic bone. The mean Mayo Elbow Performance Score improved from 44 pre-operatively to 82 at most recent follow-up. Mean VAS scores improved from 5.9 pre-operatively to 2.8 at most recent follow-up. Patients rated the affected elbow a mean of 73% as compared to the contralateral/normal side (50–100%). Apart from a 10% incidence of transient ulnar nerve neurapraxia in patients who had a medial or combined approach, complication rates and functional outcomes were comparable between medial, lateral and combined approaches. Conclusion:. Open release for post-traumatic elbow stiffness results in satisfactory functional outcomes in the majority of cases, with no significant differences between medial, lateral or combined approaches

Introduction. Snapping hip syndrome is a common condition affecting 10% of the population. It is due to the advance of the iliotibial band (ITB) over the greater trochanter during lower limb movements and often associated with hip overuse, such as in athletic activities. Management is commonly conservative with physiotherapy or can be surgical to release the ITB. Here we carry out a systematic review into published surgical management and present a case report on an overlooked cause of paediatric snapping hip syndrome. Materials & Methods. A systematic review looking at published surgical management of snapping hip was performed according to PRISMA guidelines. PubMed, MEDLINE, EMBASE, CINAHL and the Cochrane Library databases were searched for “((Snapping hip OR Iliotibial band syndrome OR ITB syndrome) AND (Management OR treatment))”. Adult and paediatric published studies were included as few results were found on paediatric snapping hip alone. Results. 1548 studies were screened by 2 independent reviewers. 8 studies were included with a total of 134 cases, with an age range of 14–71 years. Surgical management ranged from arthroscopic, open or ultrasound guided release of the ITB, as well as gluteal muscle releases. Common outcome measures showed statistically significant improvement pre- and post-operatively in visual analogue pain score (VAPS) and the Harris Hip Score (HHS). VAPS improved from an average of 6.77 to 0.3 (t-test p value <0.0001) and the HHS improved from an average of 62.6 to 89.4 (t-test p value <0.0001). Conclusions. Although good surgical outcomes have been reported, no study has reported on the effect of rotational profile of the lower limbs and snapping hip syndrome. We present the case of a 13-year-old female with snapping hip syndrome and trochanteric pain. Ultrasound confirmed external snapping hip with normal soft tissue morphology and radiographs confirmed no structural abnormalities. Following extensive physiotherapy and little improvement, she presented again aged 17 with concurrent anterior knee pain, patella mal-tracking and an asymmetrical out-toeing gait. CT rotational profile showed 2° of femoral neck retroversion and excessive external tibial torsion of 52°. Consequently, during her gait cycle, in order to correct her increased foot progression angle, the hip has to internally rotate approximately 35–40°, putting the greater trochanter in an anterolateral position in stance phase. This causes the ITB to snap over her abnormally positioned greater trochanter. Therefore, to correct rotational limb alignment, a proximal tibial de-rotation osteotomy was performed with 25° internal rotation correction. Post-operatively the patient recovered well, HHS score improved from 52.5 to 93.75 and her snapping hip has resolved. This study highlights the importance of relevant assessment and investigation of lower limb rotational profile when exploring causes of external snapping hip, especially where ultrasound and radiographs show no significant pathology

Trigger finger is one of the most common problems presenting to hand clinics in the UK. Traumatic and compressive forces created through digital movement leads to thickening of the flexor tendon sheath. The most successful methods used to treat trigger finger are corticosteroid injection and surgical release. The ring, thumb and middle finger are the most frequently affected digits. The incidence of multiple digits being affected is between 20% and 24%, with a higher incidence in Diabetes Mellitus sufferers. We report a case of failed injection therapy in a patient with multiple trigger digits, review the literature and advocate the use of surgical release as a first line treatment option in those patients with multiply involved digits

Introduction. Tennis and Golfers elbows (TE, GE) are difficult conditions to treat. Ultrasound guided steroid injection (UGSI) is one of the treatment modalities in treating refractory TE and GE. We present our clinical experience and short to mid-term results of patients with TE and GE treated with UGSI. Methods. Patients with persistent TE and GE treated with UGSI (Marcaine and kenalog) at a tertiary centre between 2007 and 2010 were retrospectively reviewed. Mean follow up was 4 months (Range 2–21 months). Patients were assessed for pain relief, recurrence of symptoms and surgical release. Results. USGI was performed on 181 elbows (144 patients). There were 68 male and 76 female patients. Mean age 49.5 years (range 17–82). At the time of UGSI, chronic features of TE were established in 144 elbows and signs of GE were identified in 37 elbows. At the review clinic, 155 (86%) elbows were reported to be completely pain free, 10 (5%) elbows experienced no improvement and 16 (9%) elbows encountered residual symptoms. However, a total of 98 (54%) elbows experienced recurrence of symptoms. For TE, symptoms recurred in 74/144 (51%) elbows at a mean interval of 5.8 months (95% CI: 4.6 to 6.9 months). For GE, symptoms recurred in 24/37 (64%) elbows at a mean interval of 4.2 months (95% CI: 3.4 to 5.0 months). Repeat USGI was performed in 24 elbows, of which 20 elbows were associated with further recurrence. Fifty seven (50%) elbows underwent surgical release (45 TE and 12 GE). Discussion. USGI appears to be a beneficial short term measure in controlling the symptoms of TE and GE. However, recurrence or failure to improve occurred in 68% of elbows. Repeat USGI is associated with high failure rate (83%) and surgical option should be explored in these refractory conditions

Introduction. Total hip arthroplasty (THA) is a common operation. Different operative approaches have specific benefits and compromises. Soft tissue injury occurs in total hip arthroplasty. This prospective study objectively measured muscle volume changes after direct anterior and posterior approach surgeries. Methods. Patients undergoing Direct Anterior Approach (DAA) and Posterior Approach (PA) THA were prospectively evaluated. 3 orthopaedic surgeons performed all surgeries. Muscle volumes of all major muscles around the hip were objectively measured using preoperative and 2 different postoperative follow-up MRIs. 2 independent measurers performed all radiographic volume measurements. Repeated-measures ANOVA was used to compare mean muscle volume changes over time. Student's t-test was used to compare muscle volumes between groups at specific time intervals. Results. MRIs for 10 DAA and 9 PA patients were analyzed. No significant differences between groups were found in BMI or Age. Pre-operative muscle volume comparisons showed no significant differences. Average postoperative follow-up times were 9.6 and 24.3 weeks. First follow-up showed significant atrophy for the DAA in Gluteus Medius (−7.3%), Gluteus Minimus (−17.5%), and Obturator Internus (−37.3%) muscles. Final follow-up showed significant recovery in Gluteus Medius (+12%) and Minimus (+11.1%) muscles. In the PA, atrophy was significant at first follow-up for Gluteus Minimus (−11.8%), Obturator Internus (−46.8%) and Externus (−16%), Piriformis (−26.5%), and Quadratus Femoris (−30.4%) muscles. Recovery was not seen in any of the significantly atrophied muscles. Muscles with significant quantified fatty atrophy at final follow-up were Obturator Internus [+5.51% (DAA); +7.65% (PA)] and Obturator Externus [+5.55% (PA)]. 3/9 PA patients demonstrated abductor tendinosis, while no DAA patients demonstrated tendinosis. Discussion. Significant atrophy for each group was seen more commonly in the anatomic regions disturbed by each approach respectively. In both approaches, muscles surgically released from their insertion showed greater atrophy, and incomplete recovery

Knee stiffness is a well-recognised postoperative problem that has been reported to occur in 6% to 15% of all patients who undergo total knee arthroplasty (TKA), and there are multiple preoperative, intraoperative, and postoperative risk factors that may predispose patients to postTKA knee stiffness. Preoperative risk factors include poor baseline range of motion (ROM), obesity, and a history of previous knee surgery and/or trauma. Potential intraoperative risk factors for having a stiff knee are malalignment, gap imbalance, and under-resection of patella. Possible postoperative risk factors include heterotopic ossification, pain, poor patient motivation, and poor physical therapy compliance. Three commonly used adjuvant treatments for this condition are custom knee devices, Botox, and ASTYM. These treatment modalities are most effective when used within 6 weeks after surgery. Multiple case series have reported that CKD can improve range of motion while maximising patient-reported functional outcomes. Botox can improve range of motion by paralyzing the muscle where the contracture is located. ASTYM therapy has recently been reported to resolve muscle contractures by effectively stimulating tissue turnover, scar tissue resorption, and regeneration of the normal soft tissue structure. When these adjuvant therapies fail, manipulation under anesthesia has been reported to be efficacious in restoring some of the original ROM. If this fails, there are surgical treatment options such as arthroscopic debridement, surgical release, revision TKA, or peroneal nerve release

The process by which pathologic scar tissue forms after TKA and restricts functional range of motion is relatively poorly understood. Arthrofibrosis may develop in patients who have normal intra-operative range of motion (ROM). However, passive flexion, extension, or both can become restricted and painful, sometimes several weeks after surgery following an early post-operative period of normal motion. The response to both nonsurgical and surgical treatment is often unsatisfactory. Arthrofibrotic scar contains dense fibrous tissue with abundant fibroblasts. Heterotopic bone is frequently found in patients with arthrofibrosis. Stiffness may result from inadequate postsurgical pain management or rehabilitation or from a biologic process that causes rapid proliferation of scar tissue. Genetic factors also may play a role, although it is difficult to predict which patients are at increased risk for arthrofibrosis after TKA. Surgical technique also can contribute; oversizing the femoral component, overstuffing the patella, or rotational malalignment can play a role. Manipulation can be helpful, particularly during the first three months after surgery. However, maintaining motion long term also requires an effective pain management and physical therapy program after manipulation. Arthroscopy may also have a role to remove scar tissue in the suprapatellar pouch and medial and lateral gutters usually between six months and one year after TKA. After one year following TKA, open surgical release or revision surgery is the most effective method to increase motion. However, only modest gains are likely to be achieved and pain may not be improved

Peri-prosthetic fractures around implants in the proximal humerus can present substantial challenges. Most individuals who undergo upper limb arthroplasty tend to be osteopenic to begin with, and the anatomy of the proximal humerus does not provide an excess of bone to work with. Therefore, peri-prosthetic fractures pose difficulties to rotator cuff function and implant stability. There are multiple classification systems, but series are small and the classification does not always lead to treatment algorithms. Risk factors for humeral fractures after shoulder arthroplasty include endosteal notching, cortical perforation, varus malalignment, stem perforation, ipsilateral shoulder and elbow arthroplasties, and loose stems. Many of these risk factors are directly related to technical errors at the time of surgery. Poor exposure can lead to aberrant starting point and errors in reaming. Oversized prostheses can lead to cortical perforation or even stem perforation. Proper positioning of the patient on the table and surgical releases help avoid these technical errors. Peri-prosthetic fractures should be carefully evaluated radiographically for stability. Two important considerations: 1. Is the implant stable? 2. Is the fracture stable? Generally, if the implant is unstable, the implant must be revised. In the setting of a stable implant, many humeral fractures can be treated nonoperatively. Many fractures at or below the level of the tip of the implant can be treated as typical humeral fractures. Options for fixation include plates with cables or long stem prostheses which bypass the fracture. Displaced tuberosity fractures are treated with suture or wire fixation. Risk factors for a poor outcome include increased time to union, skin breakdown, and stiff shoulder

Background. Steroid injections can be used safely to treat trigger fingers. We aimed to determine the accuracy of referring General Practitioner (GP) diagnoses of trigger finger made to an upper limb surgeon. We also aimed to determine the efficacy of a serial two steroid injection then surgery technique in the management of trigger fingers. Methods. Data was collected prospectively from a “one-stop” trigger finger clinic (based in a district general hospital). 200 trigger fingers identified from September 2005 to November 2008, giving a minimum 1 year follow-up. Data was analysed for correct referring diagnosis, resolution/recurrence rate following injection and the effect of age, injector grade, diabetes on the rate of recurrence. Results. GP diagnoses were correct in 94% of referrals. Recurrence free resolution after one steroid injection was achieved in 74% of cases, rising to 84% after a second injection. The grade of injector did not influence the rate of resolution (p=0.967) or recurrence (p=0.818). Age was the only statistically significant factor, with recurrences being 8.3 years younger (95% CI 4.1–12.6 yrs; p=0.0002). 15% required surgical release after failure of two steroid injections. Conclusions. Steroid injection for trigger finger is a safe, easily performed technique that can give recurrence free resolution in up to 84% using a serial two steroid injection technique. This is an easily acquired technique that has obvious potential to be performed in the primary care setting, thus reducing the burden on hospital based specialist upper limb services, as only 15% required surgical intervention

The cause of elbow tendinosis is most likely a combination of mechanical overloading and abnormal microvascular responses. Numerous methods of treatment have been advocated. In this study, we evaluated the use of platelet-rich plasma (PRP) as a treatment for resistant epicondylitis. The rationale for using platelets is that they participate predominantly in the early inflammation phases and degranulation. They constitute a reservoir of critical growth factors and cytokines which when placed directly into the damaged tissue, may govern and regulate the tissue healing process. We looked at 25 patients (19 with lateral and 6 with medial) who failed to improve after physiotherapy, cortisone injections and application of epicondylar clasps and assessed the efficacy of platelet-rich plasma injections using Gravitational platelet separation system (GPS). The cohort of patients included over a period of three years had physiotherapy, stretches, epicondylar clasp and an average of 2.9steroid injections (1–6) before having a PRP injection. The mean patient age was 43 years ranging between 24 and 54. There were 11 men and 14 women. The study included 19 patients with lateral epicondylitis and 6 patients with symptoms on the medial side. The ratio between dominant and nondominant side was according to the literature: 76%. The quick DASH scores imroved by 14% on an average in the first 3 months and further 26% in the following 9 months. 4 patients needed reintervention, 3 lateral and 1 medial and had surgical release between 6 and 12 months. 2 of them had reinjections before surgery. No local infections except mild inflammation and no systemic effects were noted. Within the limitations of being a case series and limited follow-up PRP injections provided a safe and progressive benefit over a period of 1 year in refractory cases, providing a good nonoperative alternative

We present the results of a new non-invasive lengthening nail enabling accurate control of the lengthening process and joint rehabilitation. Introduction. The use of intramedullary lengthening nails have gained popularity as they reduce common complications associated with external fixators, including infection, joint stiffness, bone regenerate deformity, late fracture and patient implant acceptance. Current nails however are associated with complications including implant breakage, mechanical failure, runaway nail and requiring MUA to restart or obtain segment lengthening. The Precice nail incorporates magnet technology with a hand held device allowing non-invasive lengthening. The nail is also reversible allowing shortening if required. Physiotherapy can continue throughout treatment to maintain joint range of motion without concern of uncontrolled nail runaway. The lengthening is axial reducing shear/torsional forces on the regenerate. Method. The lengthening of 4 femora was undertaken in 3 patients, mean age 34 yrs for post-traumatic shortening and short stature. A standard technique included an Ilizarov corticotomy followed by a 6 day latent period. Patients were mobilised partial weight bearing and knee range of motion maintained. The femora were lengthened one third of a millimetre three times per day. Radiographic and clinical review was performed every 2 weeks. Results. The desired femoral length was obtained in all patients, mean 5.6 cms (4.5–6.5). There were no complications of infection, poor bone regenerate or premature consolidation. One patient undergoing bilateral femoral lengthening underwent surgical release of a tight Tensor Fascia Lata following completion of lengthening due to hip flexion contracture. One patient required slowing of the lengthening rate due to knee flexion contracture. Physiotherapy corrected the deformity and the normal lengthening rate could be resumed. Conclusion. The Precice nail is a new device that offers accurate control of the lengthening process and rehabilitation. This should reduce complications of poor regenerate formation and soft tissue contractures

Percutaneous A1 pulley release is being increasingly used as an alternative to open surgical release and injection of local steroids for the treatment of the trigger digit. We treated 43 patients, average age 57 years (range12-78). All trigger digits were grade III-IV (Quinnell classification). A mean duration of pre-operative symptoms was 7.3 months (range 2-13 months). A percutaneous release was performed with a 19-gauge hypodermic needle under local anaesthesia in the outpatient setting. All patients were evaluated with respect to clinical resolution of symptoms and general satisfaction. We report a 97% successful release and only one case of incomplete release. A result in terms of abolishing triggering was immediate and patient acceptance was excellent. By two weeks, all the patients had no pain at the operative site. After a mean follow-up of 30.2 months (range12-50), there had been no recurrences. There were no digital nerve injuries, flexor tendon injuries, and infections. The percutaneous release is a safe and effective technique, which provides significant cost savings. The time from onset of symptoms and grading prognostically is significant and affects the treatment outcome. We recommend the percutaneous technique for typical cases of trigger finger with a palpable nodule and reproducible mechanical triggering. This technique can be the treatment of choice for the established trigger finger (grade III and IV) with symptoms of more than few months' duration. The open technique is reserved for complicated cases such as florid tenosynovitis, locked digit, failed percutaneous release or those involving the thumb

Proximal Release of Gastrocnemius (PROG) is a procedure which can be performed to treat various disorders of the foot and ankle. Gastrocnemius contracture/tightening is a condition which can lead to many chronic debilitating foot conditions like Metatarsalgia, Hallux Valgus, Plantar Fascitis, Diabetic foot ulcers etc, which in turn can significantly affect patient's quality of life. In this study we present eight cases who presented with forefoot pain, were treated with PROG and showed a complete resolution of their condition. The test used to determine Gastrocnemius contracture is the “SILFVERSKIOLD TEST”. It measures the dorsiflexion (DF) of the foot at the ankle joint (AJ) with knee extended & flexed to 90 degrees. The test is considered positive when DF at the AJ is greater with knee flexed than extended. We studied eight patients who presented to the orthopaedic outpatients between 2005 and 2010 with diverse foot conditions and having relative equinism. Six out of eight patients suffered from forefoot pain, out of which three had associated diabetic neuropathy and one out of these three had a diabetic foot ulcer. One was in association with arthritis of Talonavicular & Transmetatarsal joint, another had callosity under the head of second metatarsal. One patient had claw toes with associated Rheumatoid Arthritis. One of our patients presented with spasticity in his left calf, severe Hallux Valgus & dislocated MTPJ. He had an unsuccessful Strayer procedure on the same leg in the past. The final case had Achilles tendonitis & spurs. A finding common to all of them pre operatively was a positive Silfverskiold test, all having ZERO degree DF at the AJ with knee extended. Surgical release of the aponeurotic head of gastrocnemius was performed in prone position through a transverse incision. A cam walker was used for two weeks in those patients who were permitted to weight-bear, else a plaster for two weeks. No surgical complications occurred. Success was measured both in returning the ability to dorsiflex and resolution of related condition. DF in extension improved from an average of zero to 16(sixteen) degrees. Seven out of eight patients(including the patient with planter ulcer)had resolution of associated condition. One failure was a patient who continued to experience neuropathic pain. None of the patients complained of any weakness as a result of release. PROG is a straightforward procedure and should be considered in patients where gastrocnemius tightening is likely to be the contributing factor. This seems to improve the success of related procedures

Purpose. Recent work has shown that joint contracture severity can be decreased with the mast cell stabilizer ketotifen in association with decreased numbers of myofibroblasts and mast cells in the joint capsule of a rabbit model of post-traumatic contractures. Neuropeptides such as Substance P (SP) can induce mast cells to release growth factors. Using a gel contraction assay, we test the hypothesis that joint capsule cell-mediated contraction of a collagen gel can be enhanced with SP, but the effect is magnified in the presence of mast cells. Method. Anterior elbow joint capsules were obtained at the time of surgical release from 2 men (age 34 and 54) and 1 woman (age 40) with chronic (> 1 year) post-traumatic joint contractures. The human mast cell line HMC-1 (Mayo Clinic, Rochester), SP and the NK1 receptor antagonist RP67580 (Sigma, Oakville, ON) were used. NK1 is the SP receptor. Neutralized Collagen solution composed with 58% Vitrogen 100 purified collagen mixed with HMC-1 cells only (7.5 105), human capsule cells (2.5 105), or human capsule cells (2.5 105) and 7.5 105 mast cells (1:3) were cast into 24- well tissue culture plates. In some experiments, SP (1 × 10. −5. M) +/− RP67580 (0.5 mM) were added. The gels were maintained with 0.5 ml DMEM composed with 2% BSA and incubated at 37C for 12 h for gelation to occur. The gels were then detached from the wall and the bottom of culture plate wells, and photographed at regular intervals up to 72 hours. Gel contraction studies were carried out on passage 4 and done in triplicate for each patient. The average value of each patients triplicate was combined to give a mean contraction at each time point. Statistical analysis involved an ANOVA with posthoc Bonferroni correction. P < 0.001 was significant. Results. Mast cells alone or with SP were unable to contract collagen gels. Joint capsule cells were able to contract the collagen gels and this was enhanced in the presence of SP, although not statistically significant. Joint capsule cells combined with mast cells enhanced the gel contraction more than joint capsule cells alone or with SP (p<0.001). The addition of SP accelerated the joint capsule cell-mediated gel contraction in the presence of mast cells the greatest (p<0.001 over all other conditions). The inhibitor RP67580 completely abolished the collagen gel contraction of the joint capsule cells in all conditions. Conclusion. The in vitro experiment shows that joint capsule cell function, in the form of collagen gel contraction, is modified by the presence of mast cells and neuropeptides. These findings are significant as they strengthen the hypothesis that a myofibroblast mast cell neuropeptide fibrosis axis may be contributing to the joint capsule changes underling the loss of motion in post-traumatic joint contractures. In vivo studies with the rabbit model of post-traumatic contractures will be performed using the compounds examined in the current study

Aims

The Precice intramedullary limb-lengthening system has demonstrated significant benefits over external fixation lengthening methods, leading to a paradigm shift in limb lengthening. This study compares outcomes following antegrade and retrograde femoral lengthening in both adolescent and adult patients.

Adult presentation of neglected congenital muscular torticollis is rare. We report 12 patients with this condition who underwent a modified Ferkel’s release comprising a bipolar release of sternocleidomastoid with Z-lengthening. They had a mean age of 24 years (17 to 31) and were followed up for a minimum of two years. Post-operatively a cervical collar was applied for three weeks with intermittent supervised active assisted exercises for six weeks. Outcome was assessed using a modified Lee score and a Cheng and Tang score. The mean pre-operative rotational deficit was 8.25° (0° to 15°) and mean lateral flexion deficit was 20.42° (15° to 30°), which improved after treatment to a mean of 1.67° (0° to 5°) and 7.0° (4° to 14°) after treatment, respectively. According to the modified Lee scoring system, six patients had excellent results, two had good results and four had fair results, and using the Cheng and Tang score, eight patients had excellent results and four had good results.

Surgical management of adult patients with neglected congenital muscular torticollis using a modified Ferkel’s bipolar release gives excellent results. The range of neck movement and head tilt improved in all 12 patients and cosmesis improved in 11, despite the long-standing nature of the deformity.
