Aims. To evaluate the outcomes of cemented total hip arthroplasty (THA) following a fracture of the acetabulum, with evaluation of risk factors and comparison with a patient group with no history of fracture. . Patients and Methods. Between 1992 and 2016, 49 patients (33 male) with mean age of 57 years (25 to 87) underwent cemented THA at a mean of 6.5 years (0.1 to 25) following acetabular fracture. A total of 38 had undergone surgical fixation and 11 had been treated non-operatively; 13 patients died at a mean of 10.2 years after THA (0.6 to 19). Patients were assessed pre-operatively, at one year and at final follow-up (mean 9.1 years, 0.5 to 23) using the Oxford Hip Score (OHS). Implant survivorship was assessed. An age and gender-matched cohort of THAs performed for non-traumatic osteoarthritis (OA) or avascular necrosis (AVN) (n = 98) were used to compare complications and patient-reported outcome measures (PROMs). Results. The mean time from fracture to THA was significantly shorter for patients with AVN (2.2 years) or protrusio (2.2 years) than those with post-traumatic OA (9.4 years) or infection (8.0 years) (p = 0.03). Nine contained and four uncontained defects were managed with autograft (n = 11), bulk allograft (n = 1), or trabecular metal augment (n = 1). Initial fracture management (open reduction and internal fixation or non-operative), timing of THA (> /< one year), and age (> /< 55 years) had no significant effect on OHS or ten-year survival. Six THAs were revised at mean of 12 years (5 to 23) with ten-year all-cause survival of 92% (95% confidence interval 80.8 to 100). THA complication rates (all complications, heterotopic ossification, leg length discrepancy > 10 mm) were significantly higher following acetabular fracture compared with atraumatic OA/AVN and OHSs were inferior: one-year OHS (35.7 versus 40.2, p = 0.026); and final follow-up OHS (33.6 versus 40.9, p = 0.008). . Conclusion . Cemented THA is a reasonable option for the sequelae of acetabular fracture. Higher complication rates and poorer PROMs, compared with patients undergoing THA for atraumatic causes, reflects the complex nature of these cases.

Introduction and aim. Avascular necrosis (AVN) of femoral head remains a major post-operative complication of the surgical fixation of femoral neck fractures (#NOF). In order to reduce the incidence of AVN following this type of fracture, the National Institute for Clinical Excellence (NICE) has stated that fixation must occur within 6 hours. However, there is a paucity of information concerning whether time to fixation influences the development of AVN. The aim of the present study was to assess whether time to fixation affects the development of AVN in patients aged under 60 who had sustained a fracture (#)NOF. Methods. We looked retrospectively at 101 patients (61 female, 40 male aged under 60 (mean age 47 years) who were admitted to a multi-tertiary centre having sustained an intracapsular #NOF. The underlying co morbidity of the patient sample was varied, as was the mechanism of trauma, though in the majority of cases the cause was a simple fall. The time delay (TD) between the time of injury and the time of operation for each patient was determined. Results. 72 patients sustained an intracapsular displaced fracture and 29 an intracapsular undisplaced fracture. Of these, 33 patients were treated with a dynamic hip screw (DHS), 10 received a DHS plus a cannulated screw, and 54 were treated with cannulated screws only. We looked at time to fixation(TD) as follows: Group A-less than 6 hours (7 patients), Group B-6 to 12 hours (16 patients), Group C-12 to 18 hours (15 patients), Group D-18 to 24 hours (18 patients), Group E −24 to 48 hours (26 patients) and Group F- more than 48 hours(15 patients). Out of 97 patients, 15 (15.46%) developed AVN. Of these, 13 were patients who had sustained an intracapsular displaced fracture, two had sustained an undisplaced fracture. Of the intracapsular displaced fractures patients, the time to fixation varied from 3 hours to 26 hours post-trauma. Of note, twelve of these patients received a cannulated screw and only one was treated with a DHS. The two patients with an undisplaced intracapsular fracture underwent fixation at 13 and 24 hours respectively. The method of fixation was a cannulated screw. Conclusion. Current NICE guidelines state that intracapsular #NOF must be fixed within 6 hours in order to prevent AVN of femoral head. In our sample, 15.46% of patients developed AVN post-fixation. Crucially, 2 patients out of the 7 patients (28.57%) developed AVN despite undergoing fixation within 6 hours. Interestingly, we have observed that fracture fixation with a cannulated screw has a greater propensity to develop AVN despite time to fixation, since 15.46% of patients treated in this manner developed AVN. Taken together, method of fixation rather than time to fixation appears to be a key factor in the incidence of AVN in our patient group

Historically avoidance of avascular necrosis (AVN) has been the primary objective in the management of an acute unstable slipped upper femoral epiphysis (SUFE). When achieved through pinning in situ it was invariably associated with significant malunion. With increasing appreciation of the consequences of femoroacetabular impingement, modern techniques aim to correct deformity and avoid AVN. Exactly what constitutes an acute unstable SUFE is a source of debate but should represent 5–10% of all cases. This audit reviewed cases over the past 25 years treated in one region. Of 89 patients with 113 slips, 21 hips were recorded as unstable. During this period the management has evolved from closed reduction and stabilization through pinning in situ, to open reduction. Radiographic outcomes following these three treatment methods were compared with record of any subsequent surgery in the form of osteotomy or total hip arthroplasty. Currently the lowest reported incidence of AVN in patients with an acute unstable slip is associated with the Parsch technique which combines open arthrotomy, digital reduction and screw fixation. Early outcomes with this technique are in accordance with those reported in the literature and represents a significant improvement in outcome when compared to earlier techniques used in the management of the severe unstable SUFE

We have compared the results and complications after closed and open reduction with internal fixation in young adults with displaced intracapsular fractures (Garden grades III and IV) of the neck of the femur. We also studied the risk factors which influenced nonunion and the development of avascular necrosis (AVN). A total of 102 patients aged between 15 and 50 years was randomised to receive either closed or open reduction. Both groups were compared for age, gender, time to surgery and posterior comminution as well as for union and complications. Using univariate and multivariate analysis the factors influencing nonunion and AVN were assessed. Of the 102 patients, 92 were available for review. There was no significant difference between the groups in terms of union (p = 0.93) and AVN at two years (p = 0.85). Posterior comminution, poor reduction and improper placement of the screws were the major factors contributing to nonunion. The overall incidence of AVN was 16.3% (15 of 92 patients) and it was not influenced by these factors. A delay of more than 48 hours before surgery did not influence the rate of union or the development of AVN when compared with operation within 48 hours of injury

Aims

There has been an increasing use of early operative fixation for scaphoid fractures, despite uncertain evidence. We conducted a meta-analysis to evaluate up-to-date evidence from randomized controlled trials (RCTs), comparing the effectiveness of the operative and nonoperative treatment of undisplaced and minimally displaced (≤ 2 mm displacement) scaphoid fractures.

Neglected fractures of the femoral neck, common in young adults in underdeveloped countries, may be complicated by nonunion or avascular necrosis (AVN). We treated 52 cases by open reduction, fixation by compression screw and a free fibular graft. The mean delay between injury and operation was 5.1 months. Of 40 fractures assessed at a mean of 58.8 months (24 to 153), 38 were found to be united and two, owing to surgical errors, were not. Seven of eight heads which were avascular before operation revascularised without collapse, while seven others developed AVN after the procedure. At the last follow-up considerable collapse was apparent in five femoral heads, and 11 hips had developed coxa vara. The fibular graft had fractured in four cases. The hip had been penetrated by the screw in six cases and by the graft in three. Hip function was excellent in seven patients, good in 21 and fair in seven. Five patients had poor results. Incorporation of the fibular graft was seen after four years: in many cases the graft had been almost completely resorbed. We recommend this procedure for the treatment of neglected fractures of the neck of the femur in young adults to reduce resorption of the neck, AVN and nonunion

Prophylactic fixation of the contralateral hip in cases of unilateral slipped capital femoral epiphysis (SCFE) remains contentious. Our senior author reported a 10 year series in 2006 that identified a rate of subsequent contralateral slip of 25percnt; when prophylactic fixation was not performed. This led to a change in local practice and employment of prophylactic fixation as standard. We report the 10 year outcomes following this change in practice. A prospective study of all patients who presented with diagnosis of SCFE between 2004 and 2014 in our region. Intra-operative complication and post-operative complication were the primary outcomes. 31 patients presented during the study period: 16 male patients and 15 female patients. The mean age was 12.16 (8–16, SD 2.07). 25 patients had stable SCFE and 5 had unstable SCFE. Stability was uncertain in 1 patient. 25 patients had unilateral SCFE and 6 had bilateral SCFE. 24 patients who had unilateral SUFE had contralateral pinning performed. 1 unilateral SCFE did not have contralateral pinning performed as there was partial fusion of physis on contralateral side. In the hips fixed prophylactically there was 1 cases of transient intraoperative screw penetration into the joint and 1 case of minor wound dehiscence. There were no cases or chondrolysis or AVN. There were no further contralateral slips. This change in practice has been adopted with minimal complication. The fixation of the contralateral side is not without risk but by adopting this model the risk of subsequent slip has been reduced from 25percnt; to 0percnt;

Twenty-three patients with thirty hips of slipped capital femoral epiphysis were treated in our department, KK Women's and Children's Hospital, Singapore between 1997 and 2005. Except one patient lost of follow-up, twenty-four SCFEs with more than 2 years (25 to 73 months, average 38.5 months) follow-up were reviewed. This study is to evaluate the effectiveness and outcome of our protocol: Russell traction followed by gentle manipulative reduction with a single screw fixation & spica cast immobilization (for acute-on-chronic cases with unstable and reducible SCFE). In this series, there were 13 boys & 5 girls, mean age 12 year old ranging from 10 to 14 years. Among them 7 were Chinese, 6 Malays & 5 Indians. There were 12 unilateral cases (8 on the left & 4 right, 67%) & 6 bilateral cases (33%), including 2 patients found contralateral SCFE subsequently 1 year postoperatively. Acute-on-chronic SCFE were 16 & chronic SCFE 8. 16 were Grate I & 8 Grate II. Russell traction was on preoperatively with an average of 6 days. Gentle manipulative reduction under general anesthesia was performed in 20 SCFEs (12 GI & 8 GII) and 17 of them were successful. Fixation with a single screw was used for all cases except one hip with 2 screws. Average follow-up was 38.5 months. Good results achieved. All patient were symptom free with good function. No complications of AVN, chondrolysis, screw loosening and reslipping of the affective hips. Our protocol of management for SCFE has been largely successful in term of manipulative reduction and fixation

Introduction. An aneurysmatic bone cyst (ABC) is a benign cystic lesion of bone composed of blood-filled spaces separated by connective septa. The most common treatment is curettage with or without bone grafting. Curettage with bone grafting and Ethibloc injection therapy have a comparable recurrence rate. Ethibloc is a radiopaque alcohol solution of corn protein which is percutaneously injected in the ABC. Objective. To compare percutaneous Ethibloc injection (ETHI) with curettage with bone grafting (CUBG) in the treatment of ABC. Methods. We conducted a retrospective cohort study of 73 treatments on 56 patients with ABC, between 1985 and 2007. The number of treatments were divided in two groups, one consisting of treatments with ETHI (n=35) and the other of treatments with CUBG (n=38). Both groups are comparable for the number of primary lesions; ETHI (n=17) and CUBG (n=21) or recurrences; ETHI (n=18) and CUBG (n=17). Radiological and clinical outcomes were assessed pre- and post-operatively. We evaluated the outcome measures of ETHI and of CUBG during a mean of 24.7 (range: 2–48) months. We evaluated the recurrence rate in both groups for a maximum period of 4 years to prevent the influence of outliers. Recurrence was defined as a radiological progression/recurrence of the lesion or progression/persistence of symptoms (pain, tumor, function impairment). Statistical analysis included a Kaplan Meier survival analysis, a cox-regression analysis to account for potential confounders and a chi-square test. Results. A survival analysis showed no difference in recurrence rate between both groups. A cox regression analysis showed that type of treatment, after correcting for size of tumor, location and previous treatment, had no influence on recurrence rate. There was no significant difference in clinical outcome in both groups; complete relief of all symptoms was found after ETHI and CUBG n=30 (86%) and n=33 (87%) respectively. Radiologically, 24 (69%) of the treatments with ETHI were effective (no recurrence) in 24 months (range: 3–48) and 28 (74%) of the treatments with CUBG in 23 months (range: 2–48). There was no significant difference between the ETHI vs. CUBG in the number of effective treatments in both primarily treated ABC's (10 vs. 15, p=0.3) as in ABC's with previous treatments (14 vs. 13, p=0.6). Complications after ETHI consisted of 2 fistulas and after CUBG of an AVN and failure of reconstruction. Discussion. This study shows that the relatively simple, percutaneous Ethibloc injection is comparable to curettage with bone grafting, regarding both clinical and radiological outcome. Recurrence rate was not influenced by type of treatment, location or size of tumour. We recommend Ethibloc injection as the first-choice treatment of primary and recurrent ABC's

Introduction. Debate remains which surgical technique should be used for ankle arthrodesis. Several open approaches have been described, as well as the arthroscopic method, using a variety of fixation devices. Both arthroscopic and open procedures have good results with union rates of 93–95%, 3% malunion rate and patient satisfaction of 70–90%, although some report complication rates as high as 40%. Aims. To identify union, complication and patient satisfaction rates with open ankle fusions (using the plane between EHL and tibialis anterior). Method. A retrospective review of all isolated primary fusions performed between 2005 and 2009. Patient records were reviewed and patients were recalled for clinical evaluation and AOFAS scoring. Follow up range was 7 months–8.3 years (mean 4 years). Results. 82 ankles were identified in 73 patients. Medical notes were reviewed for all patients. Fifty five patients were clinically reviewed (75% response rate), a further 3 contacted by telephone (79% response rate). Fifeteen were not contactable. Male 47: 35 female, age range at surgery 18–75 years (mean 56.1), left 37: 45 right, 8 were smokers. Causes leading to fusion were: Trauma 52 (63%), OA 17, Rh.A 7, CMT 3, CTEV 2, Talar AVN 1. All fusions were performed with 2 (78) or 3 (4) medial tibiotalar screws. Length of stay range: 1–12 days (mean 3.1). All patients were placed in plaster post operatively for a minimum 12 weeks. Time to union ranged from 8 to 39 weeks (mean 13.3) with a union rate of 100%. Major complications were 14.6%: 7 (8.5%) malalignment, 3 (3.7%) wound problems, 2 (2.4%) complex regional pain syndrome. There were no non unions, DVT, PE, stress fractures or deep infections. There were 2 (2.4%) delayed unions (> 6 months, both smokers), 6 (7%) asymptomatic superficial peroneal nerve injuries and one saphenous nerve injury. Four (4.8%) required screw removal. Subsequent fusions were performed in 7.3%, 4 subtalar, 1 triple and 1 chopart. The AOFAS range was 8–89 (mean 66). 79% were either ‘very satisfied’ or ‘satisfied’ and 8% were ‘very disatisfied’ or ‘disatisfied’. Patients played a variety of sports including golf, squash, badmington and sky diving. Conclusion. These results show excellent union rates (100%) in part related to the strong no smoking policy and meticulous surgical technique. Two delayed unions (union at 39 and 31 weeks) were smokers. There were high satisfaction rates, however varus malalignment and persistent pain (particularly CRPS) resulted in dissatisfaction. Many patients remained highly active. These results exceed the current reported union rates and compare favourable with complications and patient satisfaction and we therefore advocate this technique

Aims

Hip fractures in patients < 60 years old currently account for only 3% to 4% of all hip fractures in England, but this proportion is increasing. Little is known about the longer-term patient-reported outcomes in this potentially more active population. The primary aim is to examine patient-reported outcomes following isolated hip fracture in patients aged < 60 years. The secondary aim is to determine an association between outcomes and different types of fracture pattern and/or treatment implants.

Aims

Outcome measures quantifying aspects of health in a precise, efficient, and user-friendly manner are in demand. Computer adaptive tests (CATs) may overcome the limitations of established fixed scales and be more adept at measuring outcomes in trauma. The primary objective of this review was to gain a comprehensive understanding of the psychometric properties of CATs compared with fixed-length scales in the assessment of outcome in patients who have suffered trauma of the upper limb. Study designs, outcome measures and methodological quality are defined, along with trends in investigation.

Aims

The aims of this study were to determine the cumulative ten-year survivorship of hips treated for acetabular fractures using surgical hip dislocation and to identify factors predictive of an unfavourable outcome.

Aims

The treatment of late presenting fractures of the lateral humeral condyle in children remains controversial.

In the time since Letournel popularised the surgical treatment of acetabular fractures, more than 25 years ago, there have been many changes within the field, related to patients, surgical technique, implants and post-operative care. However, the long-term outcomes appear largely unchanged. Does this represent stasis or have the advances been mitigated by other negative factors? In this article we have attempted to document the recent changes within the surgery of patients with a fracture involving the acetabulum, outline contemporary management, and identify the major problem areas where further research is most needed.

The aim of this study was to determine the comorbid risk factors for failure in young patients who undergo fixation of a displaced fracture of the femoral neck. We identified from a prospective database all such patients ≤ 60 years of age treated with reduction and internal fixation. The main outcome measures were union, failure of fixation, nonunion and the development of avascular necrosis.

There were 122 patients in the study. Union occurred in 83 patients (68%) at a mean follow-up of 58 months (18 to 155). Complications occurred in 39 patients (32%) at a mean of 11 months (0.5 to 39). The rate of nonunion was 7.4% (n = 9) and of avascular necrosis was 11.5% (n = 14). Failures were more common in patients over 40 years of age (p = 0.03). Univariate analysis identified that delay in time to fixation (> 24 hours), alcohol excess and pre-existing renal, liver or respiratory disease were all predictive of failure (all p < 0.05). Of these, alcohol excess, renal disease and respiratory disease were most predictive of failure on multivariate analysis.

Younger patients with fractures of the femoral neck should be carefully evaluated for comorbidities that increase the risk of failure after reduction and fixation. In patients with a history of alcohol abuse, renal or respiratory disease, arthroplasty should be considered as an alternative treatment.

We investigated whether patients who underwent internal fixation for an isolated acetabular fracture were able to return to their previous sporting activities.

We studied 52 consecutive patients with an isolated acetabular fracture who were operated on between January 2001 and December 2002. Their demographic details, fracture type, rehabilitation regime, outcome and complications were documented prospectively as was their level and frequency of participation in sport both before and after surgery. Quality of life was measured using the EuroQol-5D health outcome tool (EQ-5D).

There was a significant reduction in level of activity, frequency of participation in sport (both p < 0.001) and EQ-5D scores in patients of all age groups compared to a normal English population (p = 0.001). A total of 22 (42%) were able to return to their previous level of activities: 35 (67%) were able to take part in sport at some level. Of all the parameters analysed, the Matta radiological follow-up criteria were the single best predictor for resumption of sporting activity and frequency of participation.

We aimed to identify variables associated with clinical and radiological outcome following fractures of the acetabulum associated with posterior dislocation of the hip. Using a prospective database of 1076 such fractures, we identified 109 patients with this combined injury managed operatively within three weeks and followed up for two or more years. The patients had a mean age of 42 years (15 to 79), 78 (72%) were male, and 84 (77%) had been involved in motor vehicle accidents. Using multivariate analysis the quality of reduction of the fracture was identified as the only significant predictor of radiological grade, clinical function and the development of post-traumatic arthritis (p < 0.001). All patients lacking anatomical reduction developed arthritis whereas only 25.5% (24 patients) with an anatomical reduction did so (p = 0.05).

The quality of the reduction of the fracture is the most important variable in forecasting the outcome for patients with this injury. The interval to reduction of the dislocation of the hip may be less important than previously described.

We report the outcome of 161 of 257 surgically fixed acetabular fractures. The operations were undertaken between 1989 and 1998 and the patients were followed for a minimum of ten years. Anthropometric data, fracture pattern, time to surgery, associated injuries, surgical approach, complications and outcome were recorded. Modified Merle D’Aubigné score and Matta radiological scoring systems were used as outcome measures. We observed simple fractures in 108 patients (42%) and associated fractures in 149 (58%).

The result was excellent in 75 patients (47%), good in 41 (25%), fair in 12 (7%) and poor in 33 (20%). Poor prognostic factors included increasing age, delay to surgery, quality of reduction and some fracture patterns. Complications were common in the medium- to long-term and functional outcome was variable. The gold-standard treatment for displaced acetabular fractures remains open reduction and internal fixation performed in dedicated units by specialist surgeons as soon as possible.

Several techniques are available for the treatment of displaced fractures of the neck of the radius in children. We report our experience in 14 children treated by indirect reduction and fixation using an elastic stable intramedullary nail. The patients were followed up for a mean of 28 months. One developed asymptomatic avascular necrosis. The rest had excellent results. One had a neuropraxia of the posterior interosseous nerve, which recovered within six weeks. We advocate elastic stable intramedullary nailing for the closed reduction and fixation of these fractures in children.
