The recruitment drive, investment and collaboration within Betsi Cadwaladr University Health Board (BCUHB) sites providing specialist lower limb arthroplasty and trauma service has evolved over last few years with aims to improve patient care and reduce reliance on tertiary referral centres. Through our service-evaluation project, we reviewed the results of treatment provided for periprosthetic femur fractures (PPFFs) presenting to BCUHB sites over last 4 years.

We retrospectively reviewed consecutive PPFFs admitted at three BCUHB sites from January’20 to June’23 with mean follow-up of 20.8 ± 13.2 (8–49) months [n=161; Mean age: 82.2 ± 8.5 (59–101) years, Females:107]. Over the review period we noted a 23% increase in service demand for care of PPFFs. Majority were managed surgically [132/161] [38 revision arthroplasties; 94 ORIFs] at BCUHB sites and two patients were referred to tertiary centre. Average time to surgery was 3.5 days. 90% of the PPFFs were managed successfully with 10% (16/159) having orthopaedic complications needing further intervention. 6.3 (10/159) had medical complications and did not need orthopaedic re-intervention. In our series, 12-month re-operation rate was 6.1% (8/132) and 1-month, 3-month and 1-year mortality rate was 6.3%, 11.3% and 21.4% respectively. These results are comparable to the published results of PPFF management at tertiary centres. Potential cost savings compared to transfer to tertiary centre for PPFF management was £2.31 million. Thus, it is possible to successfully provide adequate care for PPFFs at DGHs and efforts should be made to appropriately equip and adequately staff DGHs, to provide service for local PPFF care.

Introduction

Neck of femur (NoF) fractures have an inherent 6.5% 30-day mortality as per National hip fracture database(2019). Several studies have demonstrated a higher mortality rate in covid positive NoFs but have been unable to demonstrate whether there are risk factors that contribute to the risk of mortality in this patient group or whether COVID is solely responsible for the higher mortality.

We did a retrospective comparative analysis of twenty five patients treated with Ilizarov bone transport [IBT] and twenty one patients treated with vascularised fibular graft [VFG] from 1994 to 2003 in one institution, for post traumatic tibial bone defects of more than six centimetres.

The aim of the study was to find out if there were any differences in achieving radiological end points, bone and functional score and return to work (final outcome), hospital stay and operating time (logistic factors) and complication rates. The mean defect size in the IBT group was 11.9 centimetres and in the VFG group 14.6 centimetres.

Twenty one and sixteen patients in the IBT and VFG group respectively achieved the radiological end point that is union of the defect and graft hypertrophy [p 0.5]. Nineteen patients in the IBT group and fifteen in the VFG group returned to productive work [p 0.72]. Bone and functional results were analyzed by Paley's evaluation system and there were no significant differences in the two groups of patients [bone result p 0.97 and functional result p 0.1]. The logistic factors were significantly less of IBT group [p < 0.05]. Two patients in the IBT group and one patient in the VFG group had amputation and one patient in VFG group died. Three cases in the VFG group had flap loss. Stress fracture of the graft occurred in eight patients in the VFG group [p 0.0007].

The final outcome was same in both groups. Hospital stay, operating time and refractures were significantly less in IBT group.

Distal tibial bone loss involving the ankle is a devastating injury with few options for reconstruction. The purpose of our study was to look at the long term results of ilizarov technique used to achieve lengthening of tibia and fusion at the ankle.

17 cases (16 post traumatic and one post tumor resection) admitted to one institution between 1994 and 2003. 13 cases were done in bifocal and four in trifocal mode.

The duration of follow up was 12 to 84 months The average age was 33 years (Range 7-71). The mean length of the defect was 4.5 cm (Range 1-12). Union of the fusion site occurred in 88 % (15/17) of the patients with mean duration to docking and union being 8 months. The mean time in fixator was 13 months (Range 5 to 29).

Average number of surgeries per patient was 3.2. Five patients required free vascularised grafts before the index procedure and 4 patients required realignment at the docking site. Functional results – Fourteen (77.5%) of the patients could walk without support or bracing and twelve patients (71%) returned to same or modified occupation.

Complications – Two non-union.

Deformity – Fusion site equinus deformity occurred with non union after re-fracture in one case. There were 2 cases of residual fore-foot equinus.

Residual low grade infection with discharging sinus was present in two patients. One patient needed change of wires for Pin tract infection. Our study showed 76% good and excellent scores on functional scoring but also demonstrates the high morbidity associated with this procedure. In spite of the steep learning curve and high complication rates the procedure can be undertaken in specialised centres for highly motivated patients to achieve good functional results.
