Short Term Assessment of Acetabular Cup Inclination in Outcome of Patient with Total Hip Arthroplasty in Ahvaz, Razi Hospital from 2012-14

Backgrounds and Total hip arthroplasty (THA) is most effective adult reconstructive orthopedic procedure. The implant includes acetabular (cup) and femoral part. Cup-Angle in sagittal plan, Inclination; influences wear of prosthesis. In this study we tried to assess the results of Inclination on functional outcome and quality of life in two groups of patients with Inclination≤45 and >45 degrees. Subjects and In this prospective study which was carried out on twenty patient who undergone THA between March 2012 and 2014 in Ahvaz Razi Hospital. Mean age was 54. 35 (Range25-78) and 11 men and 9 women. Patients were divided in two groups with an Inclination ˃45 and ≤45. Before the operation, Modified Harris Hip scores were completed for each patient. The mean follow up was 17. 5 months (Range 6-24). Xray was taken monthly until six months and after 1 and 2 yr of follow up. MHHS completed at end of follow up period and results were compared between groups. Variable scoring and data were analyzed with paired T test, Wilcoxon, and Man-Whitney tests. 12 patients had Inclination≤ 45 and 8 patients had Inclination >45. Mean total score before and after THA were 33. 45& 68. 35. Analysis of data showed that pain، limping، need for walking-aid، ability of walking, ability of staring، shoe-wearing، sitting-time، limb leg discrepancy and range of motion were not significantly different between two groups (P>0. 05). This study suggests that cup Inclination does not influence the functional outcome and quality of life in THA patients on follow up.
