To determine the outcome of subtrochanteric fractures treated by intramedullary (IM) nailing and identify causes for implant failure.

We performed a retrospective analysis of all subtrochanteric fractures treated by intramedullary nailing in Belfast trauma units between February 2006 and 2009. This subgroup of patients was identified using the Fractures Outcome Research Database (FORD). Demographic data, implant type, operative details, duration of surgery and level of operator were collected and presented. Post-operative X-rays were assessed for accuracy of reduction.

One hundred and twenty two (122) patients were identified as having a subtrochanteric fracture treated by IM nailing. There were 79 females and 43 males. Age range was 16 to 93 (mean 78). 95 (78%) cases were performed by training grades and 27 (22%) by consultants. Duration of surgery ranged from 73–129mins (mean 87mins). 47 patients (38.5%) were found to have a suboptimal reduction and 75 patients (61.5%) had an anatomical reduction on immediate post-operative x-ray. One year from surgery 73/122 patients were available for follow up. Of those patients with suboptimal reduction, 13/47 (27.7%) required further surgery. 8 required complete revision with bone grafting, and 5 underwent dynamisation. A further 6 patients had incomplete union. In the anatomical group, 4 patients underwent further surgery (5%). 3 required dynamisation and one had exchange nailing for an infected non-union. 3 patients had incomplete union at last follow up. 5/47 (10.6%) had open reduction in the suboptimal group compared to 25/75 (33.3%) in the anatomical group. Of the 27 cases performed by consultants, 13 (48%) were open reduction, compared to 17/93 (18%) by training grades.

This study has shown that inadequate reduction of subtrochanteric fractures, leads to increased rates of non union and ultimately implant failure. We recommend a low threshold for performing open reduction to ensure anatomical reduction is achieved in all cases.

Introduction

The addition of hydroxyapatite in cementless total knee arthroplasty is believed to reduce the time for implant fixation and rehabilitation, reduce the incidence of RLLs and provide long lasting implant stability, through improved osseointegration. We report the results of a prospective, randomised controlled single blinded study comparing the post operative pain, biological fixation and clinical outcomes with the LCS Complete Porocoat and the hydroxyapatite-coated, LCS Complete Duofix mobile-bearing knee systems.

Methods

Two hundred and four patients for TKA were prospectively recruited into the study between November 2006 and November 2008. Subjects were randomly assigned to receive the LCS Complete Duofix or LCS Complete Porocoat knee systems. Outcomes including VAS pain scores, American Knee Society scores and Oxford knee scores were performed pre-operatively and at 3 months. X-rays were analysed by an independent reviewer for the presence of radiolucent lines.

In response to the recent publication in April 2007 of NICE guidelines on venous thromboembolism, we report our practice and experience of VTE in adult hip and knee arthroplasty.

It is generally agreed that the 2 major complications of VTE are sudden death as a result of pulmonary embolism and post thrombotic syndrome. NICE guidelines make 2 assumptions:

That chemical and mechanical prophylaxis can reduce these complications

That Orthopaedic surgery, in particular elective Primary Joint Replacements are particularly high risk procedures with respect to these 2 complications.

We have studied a large cohort of patients who had Aspirin only as chemical prophylaxis to determine the incidence of clinical thromboembolism before and after discharge and the mortality from PE at 90 days. We performed a prospective analysis of consecutive patients undergoing primary total knee and hip replacement from November 2002 to November 2007. In total 2050 patients had total knee replacement and 2203 patients had total hip replacement. All patients were treated at one specialist centre under the care of one surgeon. Data was complete and accurate for all patients at 90 days post-operatively.

Standard practice was the use of 150mg Aspirin from Day 1 post-operatively for a total of six weeks combined with spinal anaesthesia and early mobilisation.

The overall rate for Fatal Pulmonary embolism 0.07% (3/4253), overall death rate 0.3%(13/4253), for treated non-fatal PE 0.66% (28/4253) and for treated above knee DVT was 0.33%(14/4253).

Our data suggests that fatal pulmonary embolism is not common and does not account for most deaths following total hip and knee arthroplasty. We suggest there is no evidence that chemical/mechanical prophylaxis reduces the risk of sudden death from PE following elective primary joint replacement and with modern surgical practice elective hip and knee replacement should no longer be considered high risk procedures.
