Abstract

Background: In LCPD, the femoral head usually deforms because of the failure of the acetabulum to contain the soft head, which finally results in an abnormal morphology that causes FAI in adult life.
Aim of the Work: The purpose of our research was to assess the early clinical and radiological results after femoral head reduction osteotomy(FHRO) of a severely deformed head in late stages of LCPD.
Patients and Methods: Our prospective study was conducted at Al-Azhar University Hospitals, Cairo, Egypt, on 15-cases with a severely deformed femoral head.
Results: The mean age of the studied cases was 10.87±1.96 years and ranged between 9 and 14, and the BMI mean was 22.33±3.96 and ranged from 17 to 29 kg/m2. 10-cases(66.7%) males and 5(33.3%) females. All patients had open femoral physis; the affected side was right in 7(46.7%) and left in 8(53.3%). Concomitant surgeries done were PAO in 1(6.7%), triple pelvic osteotomy in 6(40.0%).  Relative neck lengthening in 14(93.3%), anterior offset trimming in 7(46.7%), adductor tenotomy in 3(20.0%), and Subsequent surgery needed was hardware removal in 6(40.0%). The complications were minimal, with only one patient having AVN.
Conclusion: FHRO is an appropriate treatment for a severely deformed head in LCPD.
