Early death following primary total hip arthroplasty: 1,727 procedures with mechanical thrombo-prophylaxis.

abstract：BACKGROUND:Periacetabular osteotomy improves radiographic predictors of osteoarthrosis and diminishes pain and functional impairment. No changes in function quantified by gait analysis have yet been documented. We evaluated the functional outcome of periacetabular osteotomy in relation to gait. METHODS:The gait patter...
