title: Comparison between hemiarthroplasty and total hip replacement following failure of nailed femoral neck fractures focused on dislocations.
abstract: The frequency of and the factors causing dislocations of 71 total hip replacements and 59 hemiarthroplasties following failure of nailed femoral neck fractures were investigated. Dislocations were frequent and occurred in four (6%) and seven (l2%) hips respectively. Malposition of the components increased the risk for dislocation. A well-positioned total hip replacement was more stable than a hemiarthroplasty.
