Spontaneous resolution of soft-tissue interposition after closed reduction of hip endoprosthesis dislocation.
Over a 5-year period at a single institution, 164 endoprostheses were used for the treatment of displaced femoral neck fractures. Soft-tissue restraint preservation and repair (hip capsule and labrum) is recommended to enhance stability after endoprosthesis placement. When dislocation does occur, however, this soft tissue may become interposed after closed reduction. This occurred in 2 of the dislocations reported here. In these 2 dislocations, despite the widened joint space, the range of motion was stable. Neither of these cases had a subsequent dislocation, and after 1 month, both had spontaneously narrowed their joint space back to the immediate postoperative state.
