Introduction. Distal tibial fractures are notoriously difficult to treat and a lack of consensus remains on the best approach. This study examined clinical and functional outcomes in such patients treated definitively by circular external fixation (Ilizarov). Patients and Methods: Between July 2011 and May 2016, patients with fractures extending to within 1 muller square of the ankle were identified from our prospective Ilizarov database. Existing data was supplemented by review of clinical records. Fractures were classified according to the AO/OTA classification. Functional outcome data, including general measures of health related quality of life (SF-12 and Euroqol) and limb specific scores (Olerud and Molander Score and Lysholm scores) had been routinely collected for part of the study period. Patients in whom this had not been collected were asked to complete these by post. Adverse events were documented according to Paley's classification of: problems, obstacles and complications. Results. 142 patients with 143 fractures were identified, 40 (28%) were open, 94 (66%) were intra-articular, 85 (59%) were tertiary referrals. 32% were type 1, 28%, type 2 and 40% type 3 AO/OTA severity. 139 (97%) of the fractures united (2 non-unions, 1 amputation and 2 delayed unions who remain in frames), at a median of 165 days (range 104 to 429, IQR 136 to 201). 62% united by 6 months, 87% by 9 months and 94% by 1 year. Both non-unions have united with further treatment. Closed fractures united more rapidly than open (median 157 vs 185 days; p=0.003) and true Pilon (43C3) fractures took longer to unite other fractures (median 156 vs 190 days; p<0.001). 34% of patients encountered a problem, 12% an obstacle and 10% a complication. Of the complications, 6 (4%) were minor, 5 (3.5%) major not interfering with the goals of treatment and 4 (3%) major interfering with treatment goals (including the 2 patients with non-union and 1 who underwent amputation as well as 1 significant mal-union). This will increase to 4% if the 2 delayed unions fail to unite. Overall 56% reported good or excellent ankle scores at last report, 28% fair and 16% poor. Closed, extra-articular and non-43C3 fractures had better functional outcome scores than open, intra-articular and 43C3 fractures respectively. Conclusions. This study demonstrates a high union and low serious complication rate, suggesting that external ring fixation is a safe and effective treatment for these injuries. *Judged best paper*

Introduction. Patellofemoral instability is one of the most common presentations to a children's orthopaedic clinic. Recurrent patellar dislocations and instability episodes are painful, disabling and increase the risk of irreversible chondral damage. The medial patellofemoral ligament is the primary static stabiliser to prevent lateral dislocation of the patella and is almost always torn or attenuated in these cases. Reconstruction of this ligament is commonly performed using autologous hamstring tendon however there has been some interest recently in use of quadriceps tendon as a graft. Children with patellar instability also present unique challenges due to the small size of the patella and the presence of open growth plates which may require adaptations to the common techniques. Methods. Patients undergoing medial patellofemoral ligament reconstruction using quadriceps tendon autograft were identified using electronic theatre records. Prospectively collected clinical records and imaging findings were reviewed and underlying pathology, additional procedures at time of MPFL reconstruction, current function and need for further revision surgery determined. Results. Between January 2019 and August 2023, 50 MPFL reconstructions were performed in 37 children using partial thickness quadriceps autograft. Patient age at time of surgery ranged from 5 to 17 years (median age 13 years). The technique was utilised for a variety of indications including recurrent traumatic and habitual patellofemoral instability, fixed dislocations, and revision MPFL reconstruction. Conclusion. Partial thickness quadriceps tendon autograft can be used safely to primarily reconstruct the medial patellofemoral ligament in paediatric population, including those children with open growth plates. It also has utility in revision cases following previous failed hamstring MPFL reconstruction. We have noted that the younger the child, the more distal to the physis lies the femoral point of isometricity, rendering this a safe and reproducible treatment in this age group. Use of this technique has increased in our unit as we have observed that patients seem to be satisfied with their clinical and functional outcomes with a low incidence of short- and medium-term complications

Introduction. The clinical and functional outcome following simultaneous fractures of the acetabulum and pelvic ring represent a challenge for the clinician and are currently obscure in the existing literature. Patients and Methods. Between January 2003 and July 2009 all patients with combined pelvic and acetabular fractures were included in this prospectively study. Demographic details, mechanism of injury, ISS, surgical procedures, post-operative course, length of hospital stay, and radiological (Matta's score) and functional outcomes (The Merle d' Aubigne hip score) were recorded. The minimum follow up was 12 months (12–72). Results. Out of 520 cases, 30 (21 males) patients met the inclusion criteria. The mean age was 32. 55% sustained lateral compression, 40% combined mechanism and 5% anterior/posterior type of injury pattern. 15 out of the 30 patients had sustained other injuries. The mean time from injury to definite reconstruction was 7 days (3–14). Ilioinguinal approach was used in 20 patients, Pfannestiel in 2 and Kocher-Langebeck in 4. A wheelchair was used initially in 22 cases. The median time to FWB was 3 months. One patient underwent a THR at 18 months. 19 patients scored the full 18 points of the Merle score. Matta radiological score was excellent in 16 patients, Good 11, Fair 2, Poor 1. Conclusion. The management of these injuries poses many difficulties to the trauma surgeon. With the available expertise in place good outcomes can be obtained as seen in this series of patients

Introduction. This study was performed prospectively and randomly to compare clinical outcomes of modified-Brostrom procedure using single and double suture anchor for chronic lateral ankle instability. Material & Methods. Forty patients were followed up for more than 2 years after modified-Brostrom procedure for chronic lateral ankle instability. Twenty modified-Brostrom procedures with single suture anchor and 20 procedures with double suture anchor randomly assigned were performed by one surgeon. The mean age was 30.6 years, and the mean follow-up period was 2.6 years. The clinical evaluation was performed according to the Karlsson scale and Sefton grading system. The measurement of talar tilt angle and anterior talar translation was performed through anterior and varus stress radiographs. Results. At the last follow-up, the Karlsson scale had improved significantly from preoperative average 45.4 points to 90.5 points in single suture anchor group, from 46.2 points to 91.3 points in double suture anchor group. There were 8 excellent, 10 good, and 2 fair results according to the Sefton grading system in single anchor group, and 9 excellent, 8 good, 3 fair results in double anchor group. Therefore, 18 cases (90%) in single anchor group and 17 cases (85%) in double anchor group achieved satisfactory results. Talar tilt angle had improved significantly from preoperative average 15.7° to 6.1° in single anchor group, from 16.8° to 4.2° in double anchor group. There was significant difference in postoperative talar tilt angle between single and double anchor group. Conclusion. Significant differences in clinical and functional outcomes were not found between single and double suture anchor technique. On stress radiographs for evaluation of mechanical stability, modified-Brostrom procedure using double anchor showed less talar tilt angle than single anchor technique

Background. Controversy persists regarding preference between Herbert and Acutrak screw for internal fixation of scaphoid non-union. Acutrak screw has been shown to have better biomechanical compression properties than Herbert screw in the laboratory setting. The aim of this study was to assess the clinical, radiological and functional outcome of patients treated with the two different screw systems. Methods. A retrospective review of the results of patients with scaphoid non-union treated by a single surgeon. Group 1 comprised of 61 patients treated with Herbert screw between July1996 and June2000 and Group 2 comprised of 71 patients treated with Acutrak screw between July 2000 and December 2005. Union rates were assessed radiologically and clinically. Functional outcome was measured by using modified Mayo wrist score. Results. Both groups of patients were comparable in terms of age (25.3:27.3yrs, Herbert: Acutrak) and their occupations in relation to wrist loading. The mean time interval between injury and surgery was 12.2months for Herbert group (range: 3–144months) and 17months (range: 4–180months) in Acutrak group. Time to union was similar for both groups. Union rate was 93% (66) in Acutrak compared to 77% (47) in Herbert screw. Union rate was related to fracture site (Herbert p=0.01; Acutrak p=0.0001) and higher when the screw had been placed axially (Herbert; p=0.006, Acutrak; p=0.004) in the scaphoid. Ninety seven percent of screws had been placed axially in Acutrak compared to 84% in the Herbert. Functional outcome was satisfactory in 85% of Acutrak group compared to 67% in Herbert. Wrist fusion was performed in 4 patients in Herbert group due to progressive wrist pain and in 1 patient in Acutrak group due to similar reason. Conclusion. Acutrak screw provides more accurate method of screw placement and a higher union rate when compared to Herbert screw

The use of a total hip arthroplasty with alumina on alumina bearing couple should limit the risk of wear and secondary osteolysis. From June 1999 to December 2002, we have realised a continuous series of 265 ABGII cementless THA with Alumina bearing. The average age was 58 years (22–78 years). The main causes were osteoarthritis (81%) and osteonecrosis (13%). The operation was performed through a posterior standard approach. In all cases, an anatomic cementless ABG II stem and an acetabular cementless ABG II cup were implanted. The bearing couple was always Alumina Biolox Forte with a 28 mm femoral head in 99% of cases. To date, 12 patients died and 17 patients were lost to follow up (6.4%). 224 patients (232 hips) had a regular clinical and radiological follow-up. The mean follow up was 8.5 years (5–11 years). 9 patients were revised for septic loosening (4cases), femoral fracture (4 cases) and inveterate dislocation (1 case). There was no aseptic loosening. The overall survival rate at more than 10 years is 96.6%. We deplore 2 cases of postoperative dislocation. In this series, we did not observe any breakage of ceramic implant. The clinical and functional outcome is good and stable over time with an average PMA score at 17.6 and an average Harris score at 97.3. 16 patients reported at least one or more episode of abnormal noise “Squeaking” type (6%). It is most often a mild noise and it occurs in a static bending position. This noise disappeared with time in 10 cases. It never necessitated a prosthetic revision. The radiological control does not show any wear. There is no evidence of acetabular or femoral osteolysis. The radiological implant fixation according to the Engh and ARA criteria was good and stable in all cases. This series demonstrate that the implantation of an anatomic cementless HA arthroplasty with an alumina bearing in a young and active patient prevents the risk of wear and osteolysis and improves durability over time. The use of a 28 mm head does not increase the risk of instability and we did not observe failure of the ceramic implants

Aims

Acetabular fractures in older adults lead to a high risk of mortality and morbidity. However, only limited data have been published documenting functional outcomes in such patients. The aims of this study were to describe outcomes in patients aged 60 years and older with operatively managed acetabular fractures, and to establish predictors of conversion to total hip arthroplasty (THA).

Endoprosthetic replacement of the proximal femur may be required to treat primary bone tumours or destructive metastases either with impending or established pathological fracture. Modular prostheses are available off the shelf and can be adapted to most reconstructive situations for this purpose. We have assessed the clinical and functional outcome of using the METS (Stanmore Implants Worldwide) modular tumour prosthesis to reconstruct the proximal femur in 100 consecutive patients between 2001 and 2006. We compared the results with the published series for patients managed with modular and custom-made endoprosthetic replacements for the same conditions. There were 52 males and 48 females with a mean age of 56.3 years (16 to 84) and a mean follow-up of 24.6 months (0 to 60). In 65 patients the procedure was undertaken for metastases, in 25 for a primary bone tumour, and in ten for other malignant conditions. A total of 46 patients presented with a pathological fracture, and 19 presented with failed fixation of a previous pathological fracture. The overall patient survival was 63.6% at one year and 23.1% at five years, and was significantly better for patients with a primary bone tumour than for those with metastatic tumour (82.3% vs 53.3%, respectively at one year (p = 0.003)). There were six early dislocations of which five could be treated by closed reduction. No patient needed revision surgery for dislocation. Revision surgery was required by six (6%) patients, five for pain caused by acetabular wear and one for tumour progression. Amputation was needed in four patients for local recurrence or infection. The estimated five-year implant survival with revision as the endpoint was 90.7%. The mean Toronto Extremity Salvage score was 61% (51% to 95%). The implant survival and complications resulting from the use of the modular system were comparable to the published series of both custom-made and other modular proximal femoral implants. We conclude that at intermediate follow-up the modular tumour prosthesis for proximal femur replacement provides versatility, a low incidence of implant-related complications and acceptable function for patients with metastatic tumours, pathological fractures and failed fixation of the proximal femur. It also functions as well as a custom-made endoprosthetic replacement

The open blast fracture of the pelvis is considered to be the most severe injury within the spectrum of battlefield trauma. We report our experience of 29 consecutive patients who had sustained this injury in Afghanistan between 2008 and 2010. Their median new injury severity score (NISS) was 41 (8 to 75), and mean blood requirement in the first 24 hours was 60.3 units (0 to 224). In addition to their orthopaedic injury, six had an associated vascular injury, seven had a bowel injury, 11 had a genital injury and seven had a bladder injury. In all, eight fractures were managed definitively with external fixation and seven required internal fixation. Of those patients who underwent internal fixation, four required removal of metalwork for infection. Faecal diversion was performed in nine cases. The median length of hospital stay following emergency repatriation to the United Kingdom was 70.5 days (5 to 357) and the mean total operating time was 29.6 hours (5 to 187). At a mean follow-up of 20.3 months (13.2 to 29.9), 24 patients (82.8%) were able to walk and 26 (89.7%) had clinical and radiological evidence of stability of the pelvic ring.

As a result of the increase in terrorism, injuries that were previously confined exclusively to warfare can now occur anywhere, with civilian surgeons who are involved in trauma care potentially required to manage similar injuries. Our study demonstrates that the management of this injury pattern demands huge resources and significant multidisciplinary input. Given the nature of the soft-tissue injury, we would advocate external fixation as the preferred management of these fractures. With the advent of emerging wound and faecal management techniques, we do not believe that faecal diversion is necessary in all cases.

Isolated fractures of the anterior column and anterior wall are a relatively rare subgroup of acetabular fractures. We report our experience of 30 consecutive cases treated over ten years. Open reduction and internal fixation through an ilioinguinal approach was performed for most of these cases (76.7%) and percutaneous techniques were used for the remainder. At a mean follow-up of four years (2 to 6), 26 were available for review. The radiological and functional outcomes were good or excellent in 23 of 30 patients (76.7%) and 22 of 26 patients (84.6%) according to Matta’s radiological criteria and the modified Merlé d’Aubigné score, respectively.

Complications of minor to moderate severity were seen in six of the 30 cases (20%) and none of the patients underwent secondary surgery or replacement of the hip.

We performed a prospective, randomised trial to evaluate the outcome after surgery of displaced, unstable fractures of the distal radius. A total of 280 consecutive patients were enrolled in a prospective database and 88 identified who met the inclusion criteria for surgery. They were randomised to receive either bridging external fixation with supplementary Kirschner-wire fixation or volar-locked plating with screws. Both groups were similar in terms of age, gender, hand dominance, fracture pattern, socio-economic status and medical co-morbidities.

Although the patients treated by volar plating had a statistically significant early improvement in the range of movement of the wrist, this advantage diminished with time and in absolute terms the difference in range of movement was clinically unimportant. Radiologically, there were no clinically significant differences in the reductions, although more patients with AO/OTA (Orthopaedic Trauma Association) type C fractures were allocated to the external fixation group. The function at one year was similar in the two groups.

No clear advantage could be demonstrated with either treatment but fewer re-operations were required in the external fixation group.

Fractures of the distal radius occurring in young adults are treated increasingly by open surgical techniques, partly because of concern that failure to restore the alignment of the fracture accurately may cause symptomatic post-traumatic osteoarthritis in future years. We reviewed 106 adults who had sustained a fracture of the distal radius between 1960 and 1968 and who were below the age of 40 years at the time of injury. We carried out a clinical and radiological assessment at a mean follow-up of 38 years (33 to 42).

No patient had required a salvage procedure. While there was radiological evidence of post-traumatic osteoarthritis after an intra-articular fracture in 68% of patients (27 of 40), the disabilities of the arm, shoulder and hand (DASH) scores were not different from population norms, and function, as assessed by the Patient Evaluation Measure, was impaired by less than 10%. Ordinal logistic regression analysis showed a significant relationship between narrowing of the joint space and extra-articular malunion (dorsal angulation and radial shortening) as well as intra-articular injury. Multivariate analysis revealed that grip strength had fallen to 89% of that of the uninjured side in the presence of dorsal malunion, but no measure of extra-articular malunion was significantly related to either the Patient Evaluation Measure or DASH scores.

While anatomical reduction is the principal aim of treatment, imperfect reduction of these fractures may not result in symptomatic arthritis in the long term, and this should be considered when counselling patients on the risks and benefits of the many treatment options available.
