Manipulation Stiff Arthrolysis a b s t r a c tBackground: Adequate range of knee motion is critical for successful total knee arthroplasty.While aggressive physical therapy is an important component, manipulation may be a necessary supplement. There seems to be a lack of consensus with variable practices existing in managing stiff postoperative knees following arthroplasty. Hence we aim to determine the current practice and trend among knee surgeons throughout the United Kingdom.
Aims To analyse the learning points from the first 30 days of the COVID-19 lockdown at our institution. Patients & methods Following ethical approval, data were collected prospectively on all patients admitted under orthopaedics between March 23, 2020, and April 22, 2020. This included baseline demographics (sex, age), biochemical (blood tests), radiological (chest X-ray (CXR), computed tomography (CT)), nature and mechanism of injury, comorbidities, regular medication, observations, specific respiratory symptoms of COVID-19, management, operations, time to theatre, and outcome including mortality incidence. The nature of injury and operations performed were compared to the same period of the previous year (2019). Results During the study period, 162 (74 males) patients were admitted, with a mean age of 60.7 (range 1-101, SD 2.1). On admission, 66 (41%) patients were tested for COVID, out of which eight (13.7%) patients tested positive. Subsequently, another four patients tested positive, who developed symptoms after admission. Four out 12 (33%) confirmed COVID patients died. During this period, 4/150 other patients also died of other causes (mortality incidence 2.6%). The average ages of COVID non-survivors vs survivors were 88, SD 1, vs 76, SD 12, respectively; 2/4 had concurrent diabetes and cancer, another cancer alone, and another complex autoimmune disease managed by immunosuppressive medication. Overall admissions significantly reduced by almost 50% compared with the previous year (162 vs 373, p=<0.05), including cases of polytrauma (15 vs 33). Time to surgery was increased by an average of one day, mainly due to time taken for COVID-19 swab results to come back, and in positive patients, this was an average of 2.75 days (0-13). Lymphopenia was a useful biomarker of COVID, with levels significantly different between groups (p=<0.05). Of the clinical symptoms assessed, 8/12 patients experienced positive chest symptoms or pyrexia but only four had positive CXR changes. Discussion & lessons learnt Eight out of 12 patients who contracted COVID-19 survived without needing intensive care. Non-survivors were older with significant comorbidities. Lymphopenia is a good biomarker of the disease, but suspicious CXR was not sensitive for excluding it. Trauma volume reduced. We have highlighted significant changes to expect should there be a second wave of the virus. Key lessons learnt were that reduction in trauma volume and cessation of elective operating allowed for redeployment, including taking over the minor injury unit; more senior, consultant decision-makers ‘at the front door’ reduced unnecessary admissions. Increased use of conservative practice was effective at reducing operations required. Expedited COVID swab test processing allowed early de-escalation of isolation, reducing time to surgery. We expect approximately 12% of the typical orthopaedic population to be admitted with COVID, and up to 33% of these patients...
Purpose The aim of this study was to identify factors associated with the need for open reduction in subtrochanteric femoral fractures and investigate the effect of cerclage wiring compared to open reduction alone, on the development of complications, especially infection and non-union. Methods All consecutive patients with a fracture involving the subtrochanteric region were retrospectively identified, over an 8-year period. Data documented and analysed included patient demographics, fracture characteristics, patient comorbidities, time to fracture union and development of complications. Results A total of 512 patients met the inclusion criteria (523 fractures). Open reduction was performed in 48% (247) of the fractures. Following matching and regression analysis, we identified diaphyseal extension of the fracture to be associated with an open reduction (OR: 2.30; 95% CI 1.45–3.65; p < 0.001). Open reduction was also associated with an increased risk of superficial infection (OR: 7.88; 95% CI 1.63–38.16; p = 0.010), transfusion within 48 h following surgery (OR: 2.44; 95% CI 1.96–4.87; p < 0.001) and a prolonged surgical time (OR: 3.09; 95% CI 1.96–4.87; p < 0.001). The risk of non-union, deep infection and overall mortality was not increased with open reduction. The use of cerclage wires [50 out of 201 fractures (24.9%) treated with an open reduction] to achieve anatomical reduction as compared to open reduction alone significantly reduced the risk of non-union (OR: 0.20; 95% CI 0.06–0.74; p = 0.015). Conclusion Open reduction of subtrochanteric fractures is not associated with an increased risk of deep infection and non-union, even though it is associated with an increased risk of superficial infection, prolonged surgical time and transfusion. The use of cerclage wire is associated with reduced risk of non-union with little evidence of an increase in complications. Level of evidence III.
Introduction Intramedullary (IM) nails are considered the ‘gold’ standard treatment for subtrochanteric femoral fractures. The incidence and risk factors for re-operation in subtrochanteric fractures remain unclear. Furthermore, no studies have compared the outcomes of different nailing systems used to treat subtrochanteric fractures in the same study population. Aims/objectives Our study aimed to (i) investigate the cumulative incidence and factors associated with an increased risk of re-operation in subtrochanteric fractures treated with a long intramedullary (IM) nail, (ii) compare the outcomes of subtrochanteric fractures treated with long Affixus and Gamma nails, and (iii) establish whether the addition of a proximal anti-rotation screw in the Affixus nail confers any clinical benefit. Methods A retrospective review of all adult patients admitted to a level 1 trauma centre with a subtrochanteric femur fracture treated with a long cephalomedullary IM nail over an 8-year period was conducted. Exclusion criteria were primary surgery performed at another institution, prophylactic nailing because of tumours, incomplete fractures, and patients who were lost to follow-up or died before fracture healing. Data variables were assessed for normality prior to determining the use of either parametric or non-parametric tests. Logistic regression analysis was performed to identify potential factors associated with re-operation. For the comparison between the two nail types, patients were matched into two groups of 119 each by age (10-year intervals), gender and mechanism of injury (low energy, high energy and pathological fractures). A p-value < 0.05 was considered significant. The Kaplan–Meier nail survival curve was used to demonstrate the survival of each nail. Data were analysed using the statistical package R (R version 3.6.0). Results A total of 309 subtrochanteric fractures were treated with a distally locked long IM nail (re-operation rate: 22.33%) over an 8-year period. Logistic regression identified six factors associated with an increased risk of re-operation, including age < 75 years old, use of a long Gamma nail, pre-injury coxa-vara femoral neck shaft angles, an immediate post-operative reduction angle of > 10° varus, deep wound infection and non-union. Following matching, we compared the two long cephalomedullary nailing systems used (Gamma versus Affixus nail). The only differences identified from the unadjusted analysis were a higher overall incidence of nail failure in Gamma nails due to any cause, re-operation, and impingement of the nail tip distally against the anterior femoral cortex. When we corrected for covariates, no significant differences remained evident between the two nails. From the Kaplan–Meier nail survival curves, however, the Affixus nail demonstrated better survivorship up to 5 years post-implantation in terms of nail failure and re-operation for all causes. Finally, the addition of a proximal anti-rotation screw in the Affixus nail did not seem to confer any benefit. Conclusion We reported a 22.3% re-operation rate in our cohort of subtrochanteric fractures treated with a long IM nail. We have identified six risk factors associated with re-operation: age < 75 years old, pre-injury femoral neck shaft angle, choice of nail, varus reduction angle, fracture-related infection and non-union. The addition of a proximal anti-rotation screw in the Affixus nail did not confer any benefit.
The intramedullary and intra-osseous devices for arthrodesis of the hallux MTP joint achieved good outcome in terms of AOFAS score, VAS for pain, HVA, DA, bone union, and patient satisfaction.
