Hallux abductovalgus is one of the most common deformities addressed by foot and ankle surgeons. Surgically, it can be approached using a wide variety of procedures. After performing the first metatarsal osteotomy, the final step is often to realign the great toe in a rectus position. This is performed with an osteotomy of the proximal phalanx. The Akin osteotomy is a medially based closing wedge osteotomy of the proximal phalanx. When executing the osteotomy, the goal is not only to correct abduction, but also to keep the lateral cortex intact, which allows it to act as an additional point of fixation. However, the lateral cortex can be iatrogenically compromised during surgery or in the postoperative period. We investigated the frequency of disruption of the lateral cortex, osteotomy displacement, healing time, and the need for surgical revision associated with the Akin procedure. A total of 132 patients who had undergone Akin osteotomy were included in the present retrospective study. Intraoperative fluoroscopy showed the lateral cortex was compromised in 47 (35.6%) patients and remained intact for 85 (64.4%) patients. Of the 47 (35.6%) patients with lateral cortex disruption intraoperatively, 9 (19.1%) experienced displacement during the postoperative period, of whom, 3 (6.38%) required surgical revision. Although intact during surgery, the other 6 (4.55%) patients sustained lateral cortex fractures postoperatively, 2 (33.3%) of whom required surgical revision. A statistically significant difference was found between the integrity of the lateral cortical hinge and the healing time of the osteotomy. All the osteotomies with displacement postoperatively were noted to have lateral cortex failure, either during surgery or during the follow-up period.
The purpose of this study was to compare wound complication rates after total ankle replacement in 3 groups of patients based on tobacco status. The total cohort was divided into 3 groups based on tobacco history. Group 1 included patients who were actively tobacco users. Group 2 included patients with a history of tobacco user. Group 3 served as the control group and included patients who had never used tobacco. Available charts were reviewed for patients who underwent primary total ankle arthroplasty by 1 surgeon. Patient demographics, tobacco history, and postoperative wound complications were recorded. A total of 114 patients with tobacco history were available for follow-up and were included in this study, which ranged from March 2012 to July 2017. Group 1 included 11 active smokers. Group 2 included 38 former smokers, and group 3 had a total of 65 never smokers included. The average follow-up was 28 months for group 1 (range 10-55 months), 34.1 months for group 2 (range 12-60 months), and 32.8 months for group 3 (range 11-60 months). The wound complication rate was noted to be statistically significant when comparing active smokers to never smokers using Fisher’s exact test ( P = .0223). When comparing former smokers with never smokers, the difference in wound complication rate did not reach statistical significance ( P = 0.7631). All patients underwent at least 1 concomitant procedure at the time of initial ankle replacement. Our findings show that total ankle replacement wound healing complication rates are significantly higher in active tobacco users. There was no significant difference in wound healing complications when comparing former tobacco users versus never tobacco users. Levels of Evidence: Level III: Retrospective comparative study
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
