Abstract:
Objective:To evaluate the results of treating Perthes disease by pelvic osteotomy and internal fixation with self-reinforced absorbable (SR-PLLA) rods. Methods:50 cases of Perthes disease(53 hips) were involved. According to Herring classification, there were 16 hips of type B ?5 hips of type B/C and 32 hips of type C. All patients were treated by pelvic osteotomy(Chiari)and internal fixation with self-reinforced absorbable (SR-PLLA) rods. Results:All cases were followed up for 2 months to 18 months, with an average of 6 months. All cutting bone was healed. There was no bacterial wound infection or sterile inflammatory foreign-body reaction. Failure of fixation was only occurred in one case. Bone union was seen 6 weeks to 12 weeks, with an average of 8 weeks. All patients restored normal hip joint function and had no pain. Conclusion:This operative technique is simple and can achieve reliable fixation. It can improve bone healing with a reduced healing time and avoid secondary a removal operation. This surgical procedure is an effective way to treat cutting pelvis in Perthes disease.
