Brief Summary:

Background: The aim of this study was to compare operative outcomes after lesser toe deformity correction with either proximal interphalangeal (PIP) joint arthrodesis or PIP joint resection arthroplasty.

Methods: A prospective randomized controlled trial was performed on 37 patients (48 toes) who underwent one of these two procedures. The Numeric Rating Scale (NRS) for pain, American Orthopaedic Foot and Ankle Society (AOFAS) score, osseous consolidation, and clinical outcome were evaluated preoperatively and at 6 weeks and 6 months postoperatively.

Primary Outcome Measures :
  1. Pain [ Time Frame: Change from preoperatively to 6 weeks postoperatively and to 6months postoperatively ]
    Change in pain was evaluated using the Numeric Rating Scale for pain (ranging from 0 (no pain) to 10 (maximum pain))

  2. Function [ Time Frame: Change from preoperatively to 6 weeks postoperatively and to 6months postoperatively ]
    Change in function was evaluated using the American Orthopaedic Foot and Ankle Society score (ranging from 0 (severe impairment) to 100 (no problems with foot))


Secondary Outcome Measures :
  1. Osseous consolidation [ Time Frame: 6months postoperatively ]
    Osseous consolidation of the procedure was evaluated using x-rays
