OBJECTIVE: To investigate the effectivness of the clinging lesser trochanter osteotomy with the Wagner cone in total hip arthroplasty (THA) for Crowe type IV developmental dysplasia of the hip (DDH) in adult.
METHODS: Between November 2009 and September 2012, 7 female patients (9 hips) with Crowe type IV DDH were treated by THA procedures of clinging lesser trochanter osteotomy with Wagner cone, aged 24-62 years (mean, 42 years). All patients experienced severe pain and claudication. The left hip was involved in 2 cases, the right hip in 3 cases, and bilateral hips in 2 cases. The Harris score of involved hip was 50.00?7.04. The both limps were discrepancy with an average length difference of 3.4 cm (range, 3-4 cm). The results of Trendelenburg sign were positive. X-ray films showed high complete dislocation of the involved hips.
RESULTS: The incisions healed by first intention. There was no complication such as infection, dislocation, prosthesis loosening, neurovascular injury. The average follow-up was 36.4 months (range, 25-48 months). Pain and claudication were improved and all patients could restore to work. The Harris score was improved to 83.42 +/- 6.47, showing significant difference when compared with preoperative score (t=8.90, P=0.00). The results of Trendelenburg sign were negative. X-ray films showed that all patients got a bony union at osteotomy site of greater trochanter at 3-6 months after operation. And the interface between prosthesis and bone was stable. There was no prosthesis loosening or sinking during the follow-up.
CONCLUSION: Clinging lesser trochanter osteotomy with Wagner cone could be an option to shorten the femur in THA for patients with Crowe type IV DDH. It is effective in decreasing the risk of neurovascular injury.
