THE OUTCOME OF REVISION TOTAL HIP ARTHROPLASTY IN A DISTRICT GENERAL HOSPITAL

Background: With the foreseeable increase in demand for revision hip surgery, it is likely that orthopaedic surgeons working in district general orthopaedic units will undertake an increasing number of secondary procedures. This article set out to determine whether a single orthopaedic surgeon, working in a district general hospital, could achieve results comparable to those obtained by surgeons working in specialised tertiary referral centres. Patients and methods: Complete records and serial radiographs of 72 patients (76 hips) having revision total hip arthroplasty by a single surgeon and follow-up of at least 1 year, were reviewed by an independent observer. Results: The mean follow-up period was 4 years. Indications for revision were aseptic loosening (N=51), sepsis (N=16), fracture (N=3), dislocation (N=2), and other (N=4). Complete cement removal was achieved in 97% of acetabular components revised and 88% of femoral components revised. There were no documented complications in 68% of revised hip prostheses. The complications of the remaining cases comprised trochanteric bursitis (9%), dislocation (10%), thromboembolism (5%), periprosthetic fracture (1%) and infection of the revised prosthesis (1%). None of the cases studied died as a direct result of surgery. All radiographic parameters measured were improved by revision of the prostheses. Conclusions: Orthopaedic surgeons working in district general hospitals performing 5 to 10 revision hip arthroplasties per year can achieve results comparable to those of surgeons working in specialised units.
