The long-term outcomes of posteromedial limited surgery for developmental dysplasia of the hip: a mean 17.3-year follow-up.

The objectives of this retrospective study were to evaluate long-term functional and radiological outcomes of 102 dislocated hips of 79 patients treated with the modified medial approach and to compare them with respect to both of our short-term and mid-term outcomes and also with the current literature. The mean age at operation was 11.3±4.3 months (range: 3-18 months), with a minimum follow-up of 15 years (range: 15-23 years). It was determined that 94.1% of mean hip scores were either good or excellent. Avascular necrosis, subluxation/redislocation, and secondary surgeries were 14.8, 6.9, and 7.8%, respectively. We believe this modified procedure requiring no routine arthrotomy is safe and effective.
