The purpose of this study was to compare two distinct fixation methods for a total hip replacement performed via transverse femoral shortening osteotomy for patients with severe hip dysplasia. In this retrospective study we compared two fixation methods for total hip replacement of 78 hips in 76 patients exhibiting Crowe type IV developmental hip dysplasia (DDH). The hip replacements were performed via a transverse femoral shortening osteotomy and carried out between September 2009 and December 2013. Group I patients underwent fixation of the shortened femoral segment via a cable attached to the osteotomied segment, and group II patients underwent fixation with a plate and screw. We compared the two techniques based on operating time, osteotomy site union time, Harris hip score, hip loosening signs, and overall clinical outcomes. The mean operating time for groups I and II was determined to be 116.5 ± 12.8 min and 137.7 ± 14 min, respectively (p
