CORRECTION OF HALLUX VALGUS BY SCARF OSTEOTOMY - A CLINICAL AND RADIOGRAPHICAL REVIEW OF 175 CASES

Area of Science:

• Orthopedic Surgery
• Podiatric Medicine
• Surgical Innovation

Background:

• Hallux valgus deformity presents a significant clinical challenge.
• Scarf osteotomy is a surgical technique used for correction.
• Evaluating the efficacy and safety of scarf osteotomy is crucial.

Purpose of the Study:

• To assess the radiological and clinical outcomes of scarf osteotomy in hallux valgus treatment.
• To determine the complication rates associated with the procedure.
• To evaluate the long-term effectiveness of scarf osteotomy.

Main Methods:

• Retrospective analysis of 175 scarf osteotomies (with/without Akin procedure).
• Pre- and post-operative radiological measurements (IMA, HVA, DMAA, PDPAA, translation, sesamoid position).
• Clinical evaluation using Foot and Ankle Disability Index (FADI) and American Orthopedic Foot and Ankle Score (AOFAS) over 1-10 years.

Main Results:

• Significant improvements observed in HVA (24°), IMA (11°), DMAA (12°), PDPAA (5°), and sesamoid position.
• First metatarsal translation averaged 58%.
• Marked improvements in FADI (65 to 95) and AOFAS (76 to 96) scores.
• Complication rates included recurrence (4.6%), hallux varus (6.3%), and symptomatic screws (9%).

Conclusions:

• Scarf osteotomy is a reliable and safe procedure for moderate to severe hallux valgus.
• The technique demonstrates significant improvements in both radiographic and functional outcomes.
• A notable learning curve exists, but complications are generally manageable.
