Bipolar Hip rthroplasty (BHA) is one of the options for treatment of avascular necrosis of femoral head. Acetabular erosion and groin pain are the commonest complications. We postulate that these complications are secondary to improper acetabular preparation allowing for motion between BHA head and acetabulum.

The current study retrospectively evaluated 96 hips with avascular necrosis (AVN) of femoral head treated with modified BHA. Here the acetabulum was gently reamed till it became smooth and concentric to accommodate tight fitting outer acetabular cup.

The mean age of the patients was 42 years (range, 30-59). The mean follow up was 7.52 years (range, 4-12). The Harris hip score significantly improved from preoperative 39.3 (range, 54-30) to postoperative 89.12 (range, 74-96). According to Harris hip score grades the final outcome was excellent in 52 hips, good in 28 hips and fair in 16 hips. Hip and groin pain was reported in 4 hips (4%) and did not limit activity in them. Subsidence of less than 5mm of femoral component was seen in 8 cases. The overall patient satisfaction rate was 95% with no revision. Subgroup analysis showed patients with Ficat stage 3 having better range of motion but similar Harris hip score as compared to Ficat stage 4 patients.In conclusion modified BHA for AVN hip has low incidence of groin pain, acetabular erosion, and revision in midterm follow up.
