title: Failure of closed reduction after dislocation of Austin Moore hemiarthroplasty: an analysis of risk factors a 6-year follow-up study.
abstract: The aim of this study was to determine the factors associated with failure of closed reduction of dislocated Austin Moore hemiarthroplasty for subcapital neck of femur fracture. There were 44 (1.8%) cases of dislocation for a 6-year period. There were 28 females and 12 males, and mean age was 85.6 years. Thirty-two patients (80%) had redislocations, and 13 patients (40%) required 2 or more closed reductions. Twenty-eight patients subsequently had a Girdlestone arthroplasty. Dementia and a previous failed closed reduction were associated with a higher failure rate (P = .03 and .04, respectively). Failed close reduction patients also had a higher 6-month mortality rate (P = .04). Closed reduction after Austin Moore hip dislocation has a higher failure rate significantly in patients with dementia and are associated with a higher mortality rate. We believe closed reduction should be avoided in these groups of patients, and Girdlestone procedure was considered after initial first dislocation.
