Abstract
Background: Rheumatoid arthritis (RA) is a chronic autoimmune disorder that frequently causes forefoot deformities. Arthrodesis of the first metatarsophalangeal joint is a common surgery for severe hallux valgus. However, joint-preserving surgery can maintain the mobility of the joint. This study aimed to investigate the clinical and radiographic outcomes of distal chevron metatarsal osteotomy (DCMO) for correcting hallux valgus deformity associated with RA.
Methods: Between August 2000 and December 2018, 18 consecutive patients with rheumatoid forefoot deformities (24 feet) underwent DCMO for hallux valgus with/without lesser toe surgery. Radiological evaluations were conducted, assessing the hallux valgus angle, the intermetatarsal angle between the first and second metatarsals, and the Sharp/van der Heijde score for erosion and joint space narrowing. Clinical outcomes were quantified using a visual analog scale for pain and the American Orthopaedic Foot and Ankle Society forefoot scores to measure function and alignment.
Results: The mean hallux valgus angle decreased from 38.0° (range, 25°-65°) preoperatively to 3.5° (range, 0°-17°) at the final follow-up (p < 0.05). The mean intermetatarsal angle decreased from 14.9° (range, 5°-22°) preoperatively to 4.3° (range, 2°-11°) at the final follow-up. (p < 0.05). Regarding the Sharp/van der Heijde score, the mean erosion score (0-10) showed no significant change, decreasing from 3.83 (range, 0-6) preoperatively to 3.54 (range, 0-4) at the final follow-up (p = 0.12). Recurrent hallux valgus was observed in 1 patient and postoperative hallux varus deformity was observed in 2 feet. Spontaneous fusion of the metatarsophalangeal joint developed in 1 case.
Conclusions: DCMO resulted in satisfactory clinical and radiographic outcomes for correcting RA-associated hallux valgus deformity.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
