Abstract
Introduction
The number of total hip replacements taking place across the UK continues to grow. In an ageing population, with people living longer and placing greater strain on their prostheses, the number of peri-prosthetic femoral fractures is increasing. We studied the economic impact this has on a large university teaching hospital.
Method
All patients with a peri-prosthetic femoral fracture between 24/11/2006 and 31/5/2014 were identified using theatre databases. Radiographic and case note analysis was performed for each case. Costings from finance department for implants and in-patient stay were obtained.
Results
90 cases were identified, 58 female and 32 male, with a mean age of 76 (range: 38–91). 86 fractures occurred around total hip replacements, 4 around hemi-arthroplasties. 89 of the cases were managed surgically, 66% undergoing revision and 33% receiving open reduction and internal fixation (ORIF). According to the Vancouver Classification, 3% were Type A, 79% Type B and 18% Type C. The mean length of stay for all fractures was 43 days, ranging from 5 – 179. The mean overall cost of management was £31,370 (range: £6885 – £112,327). Patients with type C fractures had the highest mean length of stay at 53 days and highest overall mean cost of £33,417.
Conclusion
When including rehabilitation costs, our study illustrated a mean cost of £31370, roughly four times the NHS tariff of £8552 and significantly greater than the £3702 per case recovered by one UK teaching hospital. This equates to an average £22000 shortfall per case for peri-prosthetic fractures alone at our institution. Although implant costs are greater, treatment with revision where appropriate allows earlier weight bearing, reduced length of stay and rehabilitation costs and lower overall cost.
