Abstract

Format: Scientific

Length of follow-up: n/a

Level of Evidence: Cross-Sectional Study (Level III)

Classification: Surgery

Purpose: Distal metatarsal osteotomies, like the chevron procedure, were once preferred for their stability and faster recovery in hallux valgus correction. However, recent advancements have increased the use of proximal procedures, such as the lapidus. This study aims to compare complications between distal and proximal hallux valgus surgeries.

Methodology & Procedure: Data was downloaded from the TriNetX Research Network on February 2, 2023 using CPT codes 28296 (chevron) and 28297 (lapidus). Inclusion criteria consisted of patients between 18 and 60 years of age and required that all subjects had at least 60 days of follow-up after surgery . There were a total of 6,675 patients identified in the study with 4,617 (74%) being chevron and 1,649 (26%) Lapidus cases. Wound dehiscence, gender, race, ethnicity and age were recorded and evaluated.

Results: There were 42 (0.9%) and 45 (2.7%) wound dehiscence cases after chevron and lapidus cases, respectively. There was no association between the occurrence of wound dehiscence and gender, race, ethnicity, and age (all P > 0.05). After adjusting for all these covariates, the procedure type (chevron vs. Lapidus) remained significant for association with wound dehiscence (OR = 3.06, 95%CI = 2.00 – 4.68).

Analysis & Discussion: Wound dehiscence rates are higher for proximal procedures compared to distal ones, even after adjusting for confounding factors. Clinicians should consider avoiding proximal procedures in patients with a history of poor wound healing. A limitation of the study is the lack of stratification between open and minimally invasive surgeries, which may bias the results toward distal procedures.
