3D-guided high-degree posterior rotational osteotomy for avascular necrosis in pediatric femoral neck fractures: A three-case study.

ABSTRACT:

Purpose

Pediatric femoral neck fractures (PFNFs) are rare (≈1% of pediatric fractures), and avascular necrosis (AVN) is a devastating complication without a universally accepted management. High-degree posterior rotational osteotomy (HDPRO) with three-dimensional (3D) navigation is a novel joint-preserving technique with the potential to improve outcomes.

Methods

A retrospective case series was conducted with three pediatric patients (2 boys, 1 girl; aged 9-15 years at injury) diagnosed with AVN secondary to PFNF. All underwent HDPRO using Stryker OrthoMap 3D navigation to reposition the viable anteromedial femoral head. Preoperative and postoperative outcomes were assessed using radiographic analysis, functional scoring (Japanese Orthopaedic Association Hip-Disease Evaluati
