Abstract
Background: Total hip Arthroplasty (THA) is one of the most common interventions in Orthopaedic surgery. Increase in incidence of THA appears likely with the growing elderly population. THA has revolutionised the management of the patients suffering from pathologies of the hip. The common indications for THA today are osteoarthritis hip, avascular necrosis hip, ankylosing spondylitis, rheumatoid arthritis and in posttraumatic hip.
 Methods: The study was carried as a retrospective study, from February 2013 to July 2014. After getting the approval from the Ethics Committee of the Institute (Annexure I) and the consent from the patients the study was conducted on 49 patients who underwent Total Hip Arthroplasty after fracture acetabulum.
 Results: Based on the treatment received for fracture acetabulum, the vertical offset measurement was done for 47 patients. The affected side was compared with the un-affected side in the patient and a restoration of vertical offset on the affected side within 20% of the unaffected side was taken as acceptable. In 31 patients acceptable vertical offset was restored.
 Conclusion: Radiological assessment of the patients was done using 4 parameters. Measurement of Vertical offset, Horizontal offset, Body lever arm and Acetabular cup inclination was done. The affected side was compared with the un-affected side in the patient and a restoration of parameters on the affected side within 20% of the unaffected side was taken acceptable.

Summary
THA done after fracture acetabulum in particular is a highly challenging surgery and has a higher failure rate when compared to total hip arthroplasty done for degenerative arthritis[1, 2]. Total hip Arthroplasty (THA) is one of the most common interventions in Orthopaedic surgery. Results: Based on the treatment received for fracture acetabulum, the vertical offset measurement was done for 47 patients. The affected side was compared with the un-affected side in the patient and a restoration of vertical offset on the affected side within 20% of the unaffected side was taken as acceptable. The affected side was compared with the unaffected side in the patient and a restoration of parameters on the affected side within 20% of the unaffected side was taken acceptable.
