title: Subluxation of the hip joint after internal fixation of a trochanteric fracture.
abstract: The authors report an unusual case of hip subluxation after internal fixation without associated sepsis. We report one recently treated case in which a 75-year-old female experienced subluxation of her hip joint after open reduction and internal fixation for a trochanteric fracture. In this paper, we describe a case of progressive, spontaneous subluxation of the hip joint over several weeks. Most previously reported cases are associated with cerebral palsy. This entity has not been reported previously. Our patient was treated by hemi-arthroplasty and repair of the disrupted capsule, and achieved a good long-term functional result. The cause of this particular condition is discussed.
