Abstract
Objectives: The aim of this study is to investigate whether rigidfixation after triple pelvic osteotomy (TPO) utilizing a 3.5-mmlocking plate and screws without hip spica cast can provide enoughstability and prevent correction loss in pediatric patients withdevelopmental dysplasia of the hip (DDH) and Legg-Calvé-Perthesdisease (LCPD).Patients and methods: A total of 21 hips of 21 pediatric patients(9 males, 12 females; mean age: 9.3±2.0 years; range, 6 to 14 years)who underwent rigid fixation with locking plate/screws after TPOfor DDH and LCPD between June 2015 and October 2018 wereretrospectively analyzed. Preoperative, immediate postoperative,and six-month follow-up anteroposterior radiographs werecompared for the Wiberg’s center-edge angle (CE), Sharp angle,acetabular coverage of the femoral head (ACFH), and center-headdistance discrepancy (CHDD). The patient demographics, surgerytime, perioperative complications were evaluated.Results: Underlying diagnosis were DDH in 14 patients andLCPD in seven patients. In patients with DDH, postoperativeevaluation showed significant increase in the mean CE angle(5.6±16.1° vs. 30.5±9.3°, respectively) and ACFH (46.4±16.8%vs. 84.5±12.1%, respectively), and a significant decrease inthe mean Sharp angle (55.3±6.2° vs. 35.6±7.8°, respectively)and CHDD (14.6±10.7% vs. 6.2±5.6%, respectively). Thefinal follow-up revealed that there was no correction loss inthese parameters. In the patients with LCPD, postoperativeevaluation showed a significant increase in the mean CE(20.1±11.1° vs. 38.3±9.6°, respectively) and ACFH (62.9±18%vs. 91.4±10.1%, respectively), and a significant decrease in themean Sharp angle (46±3.6° vs. 25.2±5.5°, respectively). Thefinal follow-up revealed that there was no correction loss inradiological parameters. No perioperative complications werenoted.Conclusion: Our study results suggest that rigid fixation constructwith a 3.5-mm locking plate and screws without hip spica cast canprovide adequate stability to allow early mobilization followingTPO in children without any loss of correction, until bony healingat the osteotomy sites.
