Middle Phalangectomy for the Correction of Macrodactyly of the 2nd Digit in an Adult Patient: A Case Report

Abstract

Macrodactyly, a rare congenital anomaly characterised by localised gigantism of one or more digits, presents significant challenges in therapeutic management due to the absence of established guidelines. The present case report explored the surgical management of an 18-year-old female patient with macrodactyly of the second digit, addressing discomfort, footwear issues and psychological distress. The study adapts techniques from prior paediatric cases to suit adult care needs, particularly focusing on middle phalangectomy as a feasible treatment option for isolated macrodactyly. Clinical examination and radiographic assessments confirmed primary macrodactyly affecting the patient’s left second toe. The surgical intervention involved middle phalangectomy, debulking of fibrofatty tissue, joint capsule and tendon repair, along with a Winograd wedge resection procedure. Postoperative care included pain management and wound dressing. Despite encountering delayed wound healing and mild necrotic changes, the patient reported manageable pain levels and expressed satisfaction with the cosmetic outcome and improved footwear options at the six-month follow-up. The present case report contributes valuable insights into the management of macrodactyly, highlighting the efficacy of middle phalangectomy in adult patients. Preoperative assessment for peripheral arterial disease is emphasised to mitigate neurovascular complications. Proactive patient counseling regarding potential postoperative complications is crucial for informed decision-making. Overall, the findings underscore the importance of tailored surgical approaches in addressing macrodactyly and improving patients’ quality of life.
