Introduction

The purpose of this study is to evaluate the radiological and clinical outcomes in Northern Ireland of free vascularised fibular bone grafting for the treatment of humeral bone loss secondary to osteomyelitis. Upper limb skeletal bone loss due to osteomyelitis is a devastating and challenging complication to manage for both surgeon and patient. Patients can be left with life altering disability and functional impairment. This limb threatening complication raises the question of salvage versus amputation and the associated risk and benefits of each. Free vascularised fibula grafting is a recognised treatment option for large skeletal defects in long bones but is not without significant risk. The benefit of vascularised over non-vascularised fibula grafts include preservation of blood supply lending itself to improved remodeling and osteointegration.

Materials & Methods

Sixteen patients in Northern Ireland had free vascularised fibula grafting. Inclusion criteria included grafting to humeral defects secondary to osteomyelitis. Six patients were included in this study. Patients were contacted to complete DASH (Disabilities of the Arm, Shoulder and Hand) questionnaires as our primary outcome measure. Secondary outcome measures included radiological evaluation of osteointegration and associated operative complications. Complications were assessed via review of Electronic Care Record outpatient and in-patient documents.

Northern Ireland has previously demonstrated high incidence of Perthes' disease (11.6 per 100,000). The aim of this study is to confirm a declining incidence in this diagnosis in Northern Ireland.

Methods

A reduction in new Perthes' patients had been noted by the senior author. A retrospective study was designed to identify patients with a new diagnosis of this disease over a 7 year period (2004–10). Clinical notes were interrogated using word searches. Further cross referencing with x-ray system reports were utilised to capture all new patients presenting with subsequently proven Perthes'. Patients not resident in Northern Ireland at the time of diagnosis were excluded. Patients with epiphyseal dysplasia or avascular necrosis secondary to treatment of developmental dysplasia of the hip were also excluded.

A previous study from this unit had demonstrated 313 new cases over the 7 year period 1992–1998, with average incidence of approximately 45/year for the population.

Results

All years in our study (2004–10) have had less than 30 for the entire population (<8.3 per 100,000). Significant variation between years with some years much less detected, so further searches are been undertaken to ensure completeness if data capture.

Increasing knee flexion following total knee arthroplasty (TKA) has become an important outcome measure. Surgical technique is one factor that can influence knee motion. In this study, it was hypothesised that stripping of the posterior knee capsule could improve flexion and range of motion (ROM) following TKA. Patients who were undergoing TKA were prospectively randomised into two groups - one group (62 patients) were allocated stripping of the posterior knee capsule (PCS), the other group (66 patients) no stripping (no-PCS). The primary outcome was change in flexion and ROM compared to pre-operative measurements at three time points; after wound closure, 3months and 1year post-operatively. Secondary outcomes were absolute measurements of flexion, extension, ROM and complications. All operations were performed by a single surgeon using the same implant and technique. All patients received identical post-operative rehabilitation. There was a significant gain in flexion after wound closure in the PCS group (p=0.022), however there was no significant difference at 3months or 1year post-operatively. Absolute values of extension (p=0.008) and flexion (p=0.001) 3months post-operatively were significantly reduced for the PCS group. The absolute value of ROM was significantly higher for the no-PCS group at 3months (p=0.0002) and 1year (p=0.005). There were no significant difference in the rate of complications. Posterior capsular stripping causes a transient increase in flexion that does not persist post-operatively. We do not recommend routine stripping of the posterior knee capsule in patients undergoing TKA.
