Minimal Invasive Hallux Valgus Surgery

CATEGORY: Bunion; Other INTRODUCTION/PURPOSE: Hallux valgus is one of the most common deformities of the adult foot, and can adversely affect quality of life, with common complaints including pain, footwear restrictions and cosmesis. Minimal Invasive Surgery (MIS) has re-emerged lately, gaining growing popularity as a surgical approach for surgical treatment of HV deformity. Advantages such as short operating time, quicker recovery, and fewer complications have attributed to MIS. However published data are still inconclusive. METHODS: The study included 40 feet (33 pts) with hallux valgus treated with MIS technique, between Apr 20016 to March 2018. Patients were included only if pre- and postoperative weightbearing X-rays at final followup (min 6m) were available. The average age was 51.3 years (range, 21 to 77), with average follow-up of 12 months (range, 6 to 24). Patients’ radiographic records were studied to evaluate postoperative change in hallux valgus angle (HVA), intermetatarsal angle (IMA) and DMAA. Clinical outcome was recorded with Patient reported outcome questioners PROMS10 and MOXFQ. RESULTS: Following surgery deformity was corrected with preoperative mean HVA of 29.8° and IMA of 14.4° compared to postoperative mean of 7.1° and 4.7°, respectively. Patient reported outcome measures recorded the efficacy of MIS for HV in terms of pain reduction and function improvement. In six feet surgery for hardware removal was performed. In one case non- union was treated with revision surgery. CONCLUSION: This study shows that MIS for HV is safe, effective and offers satisfactory surgical and clinical results.
