Abstract
|
|
|
Purpose: This study was undertaken to evaluate the effectiveness of morselized allograft impaction combined with acetabular reinforcement ring (ARR) for acetabular deficiencies.
Materials and Methods: From March 1990 to December 2000, 73 hips (63 patients) were reconstructed by the
above method. Mean subject age was 53.2 years and mean follow-up duration was 7.6 years. Acetabular deficiencies
were classified by AAOS system. Clinical result was graded according to Harris hip scoring system (HHS). Radiographic failure was defined as a breakage of the screw and/or hook, a migration of 5 mm or more in either the vertical or horizontal direction and changes in the acetabular angulation over 5 degrees.
Results: Acetabular deficiency was AAOS-type 3 in 61 hips and type 4 in 12. HHS was improved from 43 to 87
points. Moderate limping gait with groin pain was noted in 20 hips (27.4%). Overall radiographic survival rate was 78.1%. Complications were 6 infections (8.2%), 2 vascular injuries (2.7%), and 4 dislocations (5.5%).
Conclusion: In the case of severe acetabular bone loss, revision surgery with metallic supporter combined with
impaction graft is a useful method, but successful outcome is difficult to achieve. Careful attention throughout the
procedure is mandatory.
