SUPERhip Reconstruction Treatment in Patients with Congenital Femoral Deficiency of Paley's Classification Type 1b

Area of Science:

• Orthopedic surgery
• Pediatric orthopedics
• Limb reconstruction

Background:

• Congenital femoral deficiency (CFD) presents complex challenges in limb lengthening.
• Paley's classification identifies specific types of CFD, guiding treatment strategies.
• Pre-femoral lengthening procedures are crucial for optimizing outcomes in CFD patients.

Purpose of the Study:

• To evaluate the clinical and radiographic outcomes of the SUPERhip procedure.
• To assess the efficacy of the SUPERhip procedure in patients with congenital femoral deficiency type 1b.
• To determine the suitability of the SUPERhip procedure as a preparatory step for femoral lengthening.

Main Methods:

• Retrospective review of 26 patients with Paley's type 1b CFD who underwent the SUPERhip procedure between 2005 and 2020.
• Pre- and post-operative clinical and radiographic assessments were performed.
• Analysis of key radiographic parameters including Neck-Shaft Angle (NSA), Center-Edge Angle (CEA), and Acetabular Index (AI).

Main Results:

• Significant improvements were observed in all radiographic parameters: NSA (72.3° to 133.1°), CEA (16.8° to 33.5°), and AI (27.8° to 16.4°).
• The study included 26 patients (mean age 7 years), with 65.4% being female.
• A complication rate of 15.4% was noted, primarily in patients younger than 5 years.

Conclusions:

• The SUPERhip procedure is an effective and reproducible technique for correcting Paley's type 1b CFD.
• The procedure significantly improves radiographic parameters, preparing patients for subsequent bone lengthening.
• SUPERhip offers a valuable solution for managing hip joint abnormalities in CFD.
