A Case Report of Unicompartmental Knee Arthroplasty Fracture of the Femoral Component.

Introduction: Unicompartmental knee arthroplasty (UKA) is performed with yearly rate of 9% in UK, and <8% in USA. It has been shown to be a successful and less invasive alternative to complete knee arthroplasty in certain patients total knee arthroplasty (TKA). Fracture of the femoral component after (UKA) has never been reported in the literature. Consequently, to investigate the major causes and mechanisms of (UKA) failure, we present a case of femoral component failure following (UKA). Case Report: A 62-year-old patient with 2 years following an UKA presented with a right pain, stiffness, and gait abnormalities. After taking full history and careful examination and obtaining a new radiograph, a fracture of the femoral component was revealed. A revision surgery with TKA has been done, and the outcome was assessed regularly, and good results were achieved. Conclusion: The exact reason for a femoral component fracture following UKA is yet unknown. To make an early diagnosis and avoid the need for complex knee revision surgeries, long-term follow-up is crucial for early detection of the clinical signs and symptoms of implant failure.

Outcomes Following Type C Distal Humeral Fracture Fixation Using Two Different Osteosynthesis Techniques.

BACKGROUND: Distal humeral fractures are notorious injuries, and they require surgical fixation. The reliability of reconstruction devices has been a subject of debate. Our primary outcome was to detect differences, if any, between two different groups of patients using the patient-reported outcomes measurement information system (PROMIS) Global-10 form and to compare it with the Mayo elbow performance score (MEPS) results. Other secondary outcomes included the difference in union time between patients who received a reconstruction plate vs those who received a pre-contoured anatomical plate. MATERIAL AND METHODS: It is a prospective randomised study which included a total of 30 cases equally distributed into two groups. RESULTS: The mean PROMIS and MEPS scores for group A were 31.5 SD 6.6 and 77.7, respectively, compared to 33.7 SD 6.66 and 73, respectively, for the other group. Time to union was 13.4 weeks for group A and 12.6 weeks for the other group. There was no statistically significant difference between the groups regarding union and function. However, reconstruction plates were more cost effective. The correlation between the MEPS and PROMIS G scores in both groups was statistically significant. CONCLUSION: 1. Recon plates continue to be a cost-effective method of treatment in simple intra-articular fractures. 2.PROMIS is a valuable tool to be used along with other scores in future studies.

Comparison between Malerba osteotomy and combined Evans/medial displacement calcaneal osteotomies for the management of flexible pes planus in young adults: a prospective randomised control trial, three years follow-up.

PURPOSE: The aim of the current study is to evaluate the functional and radiological outcomes of Malerba osteotomy in comparison to the standardized combined Evans/Medial Displacement Calcaneal Osteotomy (MDCO) in the management of symptomatic flexible pes planus in young adults. METHODS: Prospective randomized control trial included 34 feet (33 patients), 17 cases in each group. Functionally, patients were assessed by AOFAS and FADI scores. Radiographic evaluation included calcaneal pitch, lateral talo-1st metatarsal, AP talo-first metatarsal, AP talo-calcaneal angles, and the talar coverage percentage. RESULTS: Pre-operative and three years follow-up scores and angles were compared between both groups. No statistically significant difference could be detected between both groups (P value 0.87). However, the data showed statistically significant difference in each group when comparing (pre-operative and third year follow-up scores and angles) (P value < 0.001). The mean union rate was eight weeks in Malerba group and nine weeks in Evans/MDCO group. No incidence of nonunion. Complications like calcaneocuboid subluxation, calcaneal anterior process fracture, and lateral column pain were exclusively reported in Evans/MDCO group. CONCLUSION: Malerba osteotomy is a strong valid option for the operative management of flexible pes planus in young adults. Authors recommend Malerba osteotomy in all mild and moderate deformities due to lower complication rate while the combined Evans/MDCO is preferred in severe deformity due to relatively higher corrective power with consideration of possible complications.

Mortality Following Distal Femur Fractures Versus Proximal Femur Fractures in Elderly Population: The Impact of Best Practice Tariff.

Background and objectives The mortality after hip, proximal femur, fractures in elderly patients has steadily declined in the last decade in the United Kingdom as a result of implementing of multiple protocols focusing on prompt multidisciplinary pre- and post-operative optimization and reducing time to surgery. The pinnacle of these protocols is the development of the best practice tariff as an incentive program for hospitals that meet set criteria by the National Health Service (NHS) England in managing these injuries. Until the time of writing this paper, there was no parallel program for the management of fractures involving distal femur in the elderly. The aim of this study is to evaluate the outcomes of distal femur fractures in elderly patients against proximal femur fractures regarding post-injury mortality, the prevalence of surgical treatment and time delay till surgery. Methods A retrospective study of all patients above the age of 60 admitted to Queens Hospital Burton between 2010 and 2014 with fractures involving distal end of the femur. Patient data were assessed for demographic criteria, co-morbidities as per Charleston Comorbidities Index, type of management, time-lapse before surgery and 30-day, six-month and one-year mortality. Results were compared to an age-matched control group of patients with proximal femur fractures randomly selected during the same time window. Results The main demographic criteria such as age, gender, and Charleston Comorbidities Index were similar in both groups. There were more patients treated non-operatively in the distal femur group than in the proximal femur group (15% vs 4%). Time to surgery was statistically significantly longer in distal femur group compared to the proximal femur (49.130 hours vs 34.075 hours, P = 0.041). The mortality in distal femur group was higher at all times (9.68% at 30 days, 20.32% at six months and 34.41% at one year) when compared to that in the proximal femur group (6.99% at 30 days, 14.52% at six months, 21.51% at one year). Conclusion The distal femoral fractures showed higher mortality at 30 days, six months and one year compared to the proximal femur group. This could be partly influenced by the implementation of best practice tariff in the proximal femur fracture group reflected in less time to surgery, pre- and post-operative multidisciplinary approach and more frequent operative management.

Chronic Lateral Ankle Instability: Results of Anatomic Repair with Polyester Tape Augmentation.

BACKGROUND: Ankle sprains are one of the most common injuries in both athletes and the general population. A major problem accompanying ankle injury is the high rate of recurrence, with about 20% of acute ankle sprain patients developing chronic ankle instability. Unlike acute ankle sprain, chronic ankle instability usually needs surgical intervention. Various anatomic reconstruction techniques using the ruptured ends of the ligaments to restore stability have gained popularity. The purpose of this study was to evaluate the functional results of the treatment of chronic lateral ankle instability with anatomic repair of the injured ligaments and reinforcement with polyester tape. MATERIAL AND METHODS: A prospective study of 30 consecutive patients who underwent anatomic reconstruction of the lateral ligaments using transosseous suturing and augmentation using a polyester tape done at a single centre by a single surgeon from 2016 to 2017. All patients were assessed preoperatively and postoperatively at 6 weeks, 3, 6 and 12 months. The American Orthopaedic Foot and Ankle Score (AOFAS) and Free Online Foot and Ankle Ability Measure (FAAM) were recorded and used for results analysis. RESULTS: At 12 months' follow-up, the AOFAS had improved from mean 52.47 ± 2.06 to 91.0 ± 6.03 (p< 0.001) .The FAAM mean score had improved from mean 55.21± 1.9 to 90.43 ± 4.02 Conclusion. The ankle ligament reconstruction with additional polyester tape augmentation is an effective technique in treating chronic ankle instability with a satisfactory surgical outcome.

Management of Unstable Phalangeal Shaft Fractures Using External Minifixator.

BACKGROUND: Fractures of the hand are the most common fractures in the skeletal system and phalangeal fractures constitute about 46% of all hand fractures. Operative treatment of unstable phalangeal fractures should aim at anatomic fracture reduction and stable fixation that allows early mobilization of the affected finger's joints . This study evaluates the results of fixation of unstable shaft fractures of finger proximal or middle phalanges using a non-spanning external minifixator. MATERIAL AND METHODS: 32 men and 8 women aged 17 to 60 (median, 31.25) years suffering from fractures of 44 phalanges in 40 hands were included in the study. Four of the fractured phalanges were middle phalanges and 40 were proximal phalanges .All fractures were fixed using a mini external fixator. All procedures were done under regional anaesthetic block. The fixator was applied after closed reduction of fractures. Additional procedures included wound debridement in open fractures, and tendon repair was needed in 4 cases. We excluded fractures where intraarticular fracture extension mandates open reduction and internal fixation. RESULTS: At the end of the follow-up period (mean follow-up 11.5 months), patients were assessed clinically and radiologically. 26 fingers (59.1 %) had "excellent" results , 14 fingers (31.8 %) had "good" results and 4 fingers (9.1%) had "poor" results as their P.I.P. flexion ranges were < 80˚. CONCLUSION: External fixation of displaced phalangeal shaft fractures is an effective method of treatment in terms of a minimally invasive technique with rigid fracture fixation allowing early mobilization after surgery.
