Muscular and neurologic function in patients with recurrent dislocation after total hip arthroplasty: a matched controlled study of 65 patients using dual-energy X-ray absorptiometry and postural stability tests

Twenty-two patients with recurrent dislocation after primary total hip arthroplasty (THA) were compared with 43 randomly selected, stratified THA patients without dislocation with regard to radiographic cup position; body composition of bone, fat, and muscle (lean body mass) as determined by dual-energy x-ray absorptiometry; strength in abduction and adduction; range of motion; balance; and vibration sense. Balance and sensitivity to vibration were impaired in the patients with dislocation. No differences were found in any other variables except a subset of tall men in the dislocation group.
