Abstract :

Background: Partial hip replacement (cemented or uncemented) is the frequently done surgery in elderly patients with fracture neck of femur. Austin Moore prosthesis being uncemented negates all the disadvantages of cementing, but it does come with it�s own disadvantages.

Material& Methods: We analysed results of 30 patients of fracture neck femur with Dorr type A and B proximal femoral morphology, treated by uncemented partial hip replacement (where medial calcar bone graft was used for additional lateralization of the stem of prosthesis in femoral canal along with transverse peg grafts in fenestrations to centralise the stem.

Results: The mean follow up was 9.3 years (range from 2 to 15 years). According to Harris Hip score, final outcome was excellent in 21 hips, good in 7 hips and poor in 2 hips. There was no incidence of hip dislocation.

Conclusions: Our study shows that in addition to the transverse bar by fenestration grafts, medial calcar bone block formed, prevents medialization and subsidence of the prosthesis with excellent result.
