title: Management of hip instability with a cemented, constrained acetabular component.
abstract: We evaluated the use of a cemented constrained acetabular component to treat recurrent or potential instability after hip replacement. Over a seven year period, 109 patients who had undergone 110 operations were identified from hospital records. Patients were reviewed based on clinical and radiological follow-up. Post-operative function and quality of life was assessed using the Oxford Hip Score (OHS) and SF-12. From an original cohort of 109 patients, 9 patients were lost to follow up. Of the remaining 100 patients, the mean follow up was 2.9 years (SD±2 years). There were 4 failures, requiring 3 further revisions. The mean post-operative OHS was 33, SF-12 PCS 34 and SF12 MCS 52. 5-year survivorship was 90%. Cementing a constrained acetabular component provides satisfactory mid term results in patients at high risk of hip dislocation.
