Article Synopsis
- Patients with osteonecrosis of the femoral head due to developmental dysplasia of the hip (DDH) often require total hip arthroplasty (THA), with a study noting a 14% incidence by age 34.
- Key factors linked to the need for THA include severe grades of osteonecrosis, advanced osteoarthritis, and hip subluxation, while acetabular dysplasia and prior surgeries were not significant factors.
- The findings highlight the importance of preventing osteonecrosis in DDH patients, as symptoms like severe pain and reduced mobility are commonly reported among those needing THA.
Unlabelled: In unilateral Developmental Dysplasia of the Hip (DDH), avascular necrosis (AVN), femoral or pelvic osteotomy, and residual dysplasia causing subluxation of the proximal femur may influence Leg Length Discrepancy (LLD). This can lead to gait compensation, pelvic obliquity, and spinal curvature. The aim of this study is to determine the prevalence of LLD, establish which limb segment contributes to the discrepancy, describe how AVN influences LLD, and ascertain variables that may influence the need for LLD corrective procedures.

Aim: Dual tension-band plates are used for temporary epiphysiodesis and longitudinal guided growth. The study aim was to assess rate of correction, to identify development of femoral and tibial intra-articular deformity during correction and to document resumption of growth after plate removal.
Materials And Methods: A retrospective study of 34 consecutive patients treated with dual tension-band plates between 2012 and 2020 was performed.
Introduction: Leg-length difference (LLD) is common in patients with developmental dysplasia of the hip (DDH). LLD of > 1 cm at skeletal maturity is reported in > 40% of patients, with the majority related to ipsilateral overgrowth. A longer DDH leg might lead to excessive mechanical loading at the acetabular margin, resulting in compromised acetabular development.

Our objective was to analyze femoral morphology in PD patients at skeletal maturity to assess where the LLD originates, and evaluate the effect of contralateral epiphysiodesis for length equalization on proximal and subtrochanteric femoral lengths.
Methods: All patients treated for PD in our institution between January 2013 and June 2020 were reviewed retrospectively.
