ABSTRACT

PURPOSE:

Despite many recent advances in total hip arthroplasty, dislocation remains a common postoperative complication. This study was undertaken to evaluate the incidence and causes of dislocation. MATERIALS AND

METHODS:

We experienced 16 hip dislocations in 217 cases of total hip arthroplasty performed between June 1990 and March 1999. We analyzed the incidence and causes of dislocation retrospectively. We classified the factors of dislocation as component malposition, Soft tissue imbalance and patient factor. Radiographic measurements were performed to evaluate component malposition and soft tissue imbalance. To evaluate patient factor, we analyzed the patient's past history and posture when the dislocation occurred.

RESULTS:

The leading causes of hip joint dislocation after total hip arthroplasty are acetabular component malposition (9 cases), followed by patient factor (5 cases) and soft tissue imbalance (3 cases). It took an average of 40.5 days following surgery for hip joint dislocation to occur with 13 out of 16 cases (90.2%) developing hip dislocation within 2 months.

CONCLUSION:

In order to prevent acetabular component malposition, careful insertion of acetabular component is required. Preventive measure and care should be taken during the early postoperative period. Those presenting with improper anteversion, accurate analysis of the extent of acetabular and femoral component anteversion based on CT scanning is helpful.
