Femoral Head Reduction Osteotomy for Legg-Calvé-Perthes Disease Sequelae: Case Report

Area of Science:

• Orthopedics
• Hip Preservation Surgery
• Pediatric Orthopedics

Background:

• Legg-Calvé-Perthes disease (LCPD) frequently results in hip joint morphology sequelae.
• Common sequelae include an oversized, nonspherical femoral head, short femoral neck, and elevated greater trochanter, leading to femoroacetabular impingement (FAI).
• The Ganz technique offers new FAI treatment possibilities for LCPD sequelae without increasing avascular necrosis risk.

Purpose of the Study:

• To present a case report of a patient with LCPD sequelae.
• To evaluate the efficacy of a femoral head reduction osteotomy technique for LCPD sequelae.
• To demonstrate the restoration of femoral head sphericity and management of associated FAI.

Main Methods:

• A femoral head reduction osteotomy technique was employed.
• This technique resects the damaged central portion of the femoral head in cases of ellipsoid coxa magna.
• The procedure aims to restore femoral head sphericity in LCPD sequelae.

Main Results:

• The described femoral head reduction osteotomy technique addresses the specific morphology of LCPD sequelae.
• Joint wear in ellipsoid coxa magna is concentrated centrally, leaving the lateral third intact.
• Short-term outcomes for this osteotomy technique are encouraging.

Conclusions:

• Femoral head reduction osteotomy is a viable surgical option for LCPD sequelae with specific hip morphology.
• The technique effectively resects damaged portions and restores femoral head sphericity.
• This approach shows promise for managing FAI resulting from LCPD sequelae.
