Abstract
Introduction: Fixation of porous im plant depends on bone in growth and bone on growth in hydroxyapatite coated acetabular implant, CT scans were played an important role in evaluating acetabular cup position precisely. Formation of new bone in prosthetic bone interface (osteointegration) is a good sign of stability in uncemented total hip replacement.
Aim: A study to analyse the importance of acetabular component orientation and fixation for the outcome of uncemented total hip arthroplasty.
Meterial & Methods: 18 to 60 years of aged fifteen patients underwent uncemented total hip arthroplasty through posterior approach during June2013 to March2015.Periodic evaluation of osteointegration and orientation of acetabular component was done clinically and radiologically using CT scan.
Results: Harris Hip Score improved from 29.9 preoperative to 91.4 postoperatively in our study with one case of deterioration but gave fair result. Mean acetabularante version and inclination was 21 degree and 41 degree respectively.
Conclusion: In this short term study clinical outcome correlated well with radiological appearance and had comparable results with previous studies.
Keywords: osteointegration, acetabular component, anteversion, inclination, arthroplasty.
