RESUMO
BACKGROUND AND OBJECTIVE: Since the description of the syndrome of the second intermetatarsal space, this is a common diagnosis among foot and ankle surgeons. However, no series have been published that consider this syndrome as its own entity. The objective of this study is to evaluate the clinical and radiological results of the release of the intermetatarsal ligament and minimally invasive distal metatarsal osteotomy in patients diagnosed with second space syndrome. MATERIALS AND METHODS: An observational, longitudinal, retrospective study was carried out in patients with a clinical diagnosis of second space syndrome operated on using a minimally invasive technique. For the clinical results, the visual analog scale (VAS) for subjective pain, the Manchester-Oxford Foot Questionnaire (MOXFQ) and the scale for minor metatarsals and interphalangeals of the American Orthopedic Foot and Ankle Society (AOFAS-LMTS) were used for clinical-functional assessment. Consolidation or not of osteotomies was recorded and complications were recorded. RESULTS: Twenty-nine feet in 29 patients were included in the study. After a mean follow-up of 39 months (25-50), clinically and statistically significant improvement was obtained in the scores: pain VAS, scales and subscales of the MOXFQ and the AOFAS-LMTS (p < 0.0001). All osteotomies healed at the end of follow-up and no major complications were recorded. CONCLUSIONS: Percutaneous or minimally invasive surgery, in patients with second intermetatarsal space syndrome, obtains good clinical, functional and subjective results, with few complications. Therefore, we consider it an effective, safe and recommended technique in the hands of experienced surgeons.
