Abstract
To summarize our pioneering surgical practice and clinical outcome of Crowe type III-IV developmental dysplasia of the hip (DDH) with a direct anterior approach total hip arthroplasty in a single teaching hospital in Southwest China. Fourteen patients (15 hips) diagnosed with Crowe type III-IV developmental dysplasia of the hip were involved in this single-center retrospective study between 2016 and 2018. A comprehensive surgical procedure, including preoperative planning and algorithms for leg length equalization, intraoperative stepwise soft tissue release, bone defect reconstruction, and an innovative subtrochanteric osteotomy, was described. Furthermore, advancements in intraoperative CT guidance, computer navigation, and nerve monitoring were available for specific demands. The short-term clinical outcome was evaluated at the endpoint of follow-up by three patient-reported functional scales (Harris, WOMAC, and SF-12 scores), and objective data collected at the clinic, including functional recovery (muscle strength of hip flexor and abductor, correction of the pelvic tilt, leg length discrepancy, and limp), radiographic analysis, and complication occurrence. The intraoperative variables were carefully recorded. The mean ope...Continue Reading
