ABSTRACT

Introduction: developmental dysplasia of the hip presents catastrophic complications if not treated promptly. The goal of treatment is to obtain a reduced and concentric hip. An 8-20% redislocation is reported in hips treated for the first time, failure in the surgical technique when trying to obtain a concentric and stable head is one of the main causes. Objective: to define if there is a difference between the surgical procedures on the median adductor muscle that influence the recurrence of hip dislocation in patients older than 18 months. Material and methods: all the consecutive patients between 18 and 36 months with a diagnosis of developmental dysplasia of the hip who underwent surgery for the first time from January 2019 to August 2022 at the Shriners Hospital for Children in Mexico were included. It was grouped into three groups depending on the surgical technique performed on the median adductor. Group 1: without median adductor myotomy, group 2: percutaneous myotomy and group 3: open myotomy. All the information was taken from the hospital's clinical records. Results: a total of 135 operated hips were obtained. There is evidence of a predominance in the female gender with 88% and the left hip (58.5%). Within the statistical analysis, an increased risk of redislocation was found in percutaneous versus open myotomies. Conclusion: there is an increased risk of hip redislocation with patients treated with percutaneous median adductor myotomy versus open median adductor myotomy.
