66 year old male with crowe 3 DDH lt. Hip. 3. 4 cm shortening. Pain exacerbated over last 2 months. was active swimmer till last year.
Option 1. Cemented Cup in the Psuedo-acetabulum with a cemented low offset stem.- Loosening rates of the cup are high.
2. Uncemented bantam cup in the true acetabulum, breaking the medail wall with a modular stem( SROM) in this cases with shortening if necessary with MOM or MOP bearings.we chose the latter with minimal postop problems. Ilipsoas and circumferential capsular release was done. We did not do a shortening osteotomy as the sciatic nertve was palpated and not found to be tense. the lengthening was close to 3 cm. Hamstring tightness was present postop which resolved in 6 weeks.
