title: Total Hip Arthroplasty in Patients with Skeletal Dysplasia.
abstract: 127 patients with a height ≤ 150 cm (non metric ≤ 4 feet and 11 inches) who received hip arthroplasty surgery between July 1, 2006 and May 30, 2013 at our institution were enrolled. Retrospective data evaluation was performed for two different times of follow-up (1 year and 5 years respectively). 115 patients were evaluated for 1-year follow up. Out of these, 27 patients were available for 5-year follow up. The mean Harris Hip Score increased from 40 ± 13 on admission to 82 ± 20 (P<0.001) at 1-year follow-up and 79 ± 17 (P<0.001) at 5-year follow-up. Hip arthroplasty can be performed in patients with dwarfism with good clinical benefits. However, survival rates are worse compared to the general population.
