Abstract:

BACKGROUND: Compared with the cone stem, short stem holds good matching with femoral canal, and remarkably reduces the risk of prosthesis loosening.

OBJECTIVE: To further investigate the clinical efficacy of Accolade II stem for Crowe type I developmental dysplasia of the hip.
METHODS: Clinical data of 16 patients with Crowe type I developmental dysplasia of the hip undergoing total hip arthroplasty using Accolade II stem were collected, the length of both lower limbs before and after surgery was compared, and the Visual Analogue Scale, functional recovery of the hip and general conditions were observed at 12 weeks postoperatively. 
RESULTS AND CONCLUSION: (1) The change in length of both lower limbs before and after surgery had significant difference (P < 0.05), and 10 patients (62%) with the same length of both lower limbs before surgery, and 15 cases (94%) after surgery. (2) The postoperative acetablar abducent angle was 41°-54° (average 46.9°). (3) The Visual Analogue Scale and Harris hip scores after surgery were significantly improved compared with baseline (P < 0.05). (4) The intraoperative blood loss was 147 mL on average, the mean operation time was 72 minutes, and the hospitalization time was 7.2 days. (5) All patients recovered well and no complications occurred at 3 months postoperatively. (6) To conclude, Accolade II stem is safe and reliable for Crowe type I developmental dysplasia of the hip, and exhibits good functional recovery of the hip.
