Outcomes of Hallux Valgus Corrective Osteotomy: A Tertiary Hospital Experience.

Abstract

A common form of forefoot deformity, hallux valgus (HV) is characterized by a prominent first metatarsal head, lateral deviation of the hallux, and medial deviation of the first metatarsal bone. In the case of HV, corrective osteotomies are performed with good results and patient satisfaction. A retrospective cohort study of patients who underwent corrective osteotomy for hallux valgus from 2016 to 2022 was conducted at King Abdulaziz Medical City (KAMC), Riyadh, Saudi Arabia. Data were collected by chart review using the BestCARE system. IBM SPSS Statistics for Windows, Version 23.0 (Released 2015; IBM Corp., Armonk, New York, United States) was used for statistical analysis. Our study included 166 patients. The mean age of the patients was found to be 41.3 years old and about 152 (91.6%) of them were females. The most frequently reported comorbidity was hypertension (10.2%). The mean hallux valgus angle was found to be 36.1 ± 9.9 and the mean intermetatarsal angle was found to be 15 ± 4.4 degrees. Seventy-six (45.8%) patients underwent nonoperative management first. The mean age at diagnosis among males was found to be 28.5 ± 11.3 years and among females was 37.9 ± 14.4 years; a significant difference between means was noted (p-value = 0.019) with mean age at diagnosis in males being significantly lesser than in females. Significant improvement and reduction were seen in HV angle post surgery. Nearly half of the patients underwent nonoperative management first. Age at diagnosis is significantly younger in males compared to females.
