Hallux varus following scarf osteotomy

Area of Science:

• Orthopedic Surgery
• Podiatric Surgery
• Foot and Ankle Surgery

Background:

• Hallux varus is an uncommon complication, often iatrogenic, following hallux valgus correction.
• Scarf osteotomy, a common procedure for hallux valgus, can also result in hallux varus.
• The management of iatrogenic hallux varus presents challenges due to the complexity of the deformity.

Purpose of the Study:

• To investigate the incidence and characteristics of hallux varus after Scarf osteotomy.
• To identify the etiological factors contributing to iatrogenic hallux varus post-Scarf osteotomy.
• To propose a classification system and outline management strategies for hallux varus following Scarf osteotomy.

Main Methods:

• Retrospective review of four cases of hallux varus following Scarf osteotomy.
• Analysis of patient data to identify causative factors.
• Formulation of a classification system for the deformity.
• Discussion of management based on the proposed classification.

Main Results:

• Hallux varus occurred in 1% of total Scarf osteotomy cases reviewed.
• Identified specific factors leading to iatrogenic hallux varus.
• A classification system for hallux varus deformity was developed.
• Management strategies were outlined based on the classification.

Conclusions:

• Scarf osteotomy can lead to iatrogenic hallux varus, necessitating careful surgical planning.
• A proposed classification system aids in understanding and managing this complication.
• Effective management requires addressing the underlying etiological factors of hallux varus.
