Description
Summary:Category: Lesser Toes; Bunion Introduction/ Purpose: Bunionette deformity (BD) is a painful condition of the fifth metatarsal characterized by an osseous prominence and varus deformity. The purpose of this study is to assess the clinical, functional, and radiographic outcomes of percutaneous distal metatarsal metaphyseal osteotomy (DMMO) without fixation or post-operative strapping of the foot. Methods: A retrospective case series was performed on 111 patients (132 feet) with symptomatic BD who underwent percutaneous DMMO of the fifth metatarsal from September 2020 to January 2022. Patient-reported clinical outcome measures, including the Foot Function Index (FFI) questionnaire, the Visual Analog Score (VAS), and overall satisfaction were collected. Four- Five intermetatarsal angle (IMA) correction, time to bone union, and complication rates were assessed in all patients. Results: The mean post-operative follow-up time was 24.1 months. Both radiographic parameters and patient-reported outcome measures significantly improved after DMMO procedure. The average fourth-to-fifth IMA improved from 12.2 degrees, preoperatively, to 4.4 degrees, postoperatively (p
