Effectiveness of Headless Bioabsorbable Screws for Fixation of the Scarf Osteotomy

Background:Scarf osteotomy has been used in hallux valgus surgery due to its large fixation surface for screws and low postoperative complications. However, screws may cause skin irritation from their head, which may require an additional surgical procedure to remove.Methods:This study included 115 patients (106 females and 9 males, 115 feet) who underwent hallux valgus correction with a scarf osteotomy using bioabsorbable screws between September 2010 and September 2012. Preoperative and postoperative 1-month and 1-year radiographic measurements, including intermetatarsal angle (IMA), hallux valgus angle (HVA), distal metatarsal articular angle (DMAA), proximal phalangeal articular angle (PPAA), and lateral translational distance (LTD), were obtained. American Orthopaedic Foot & Ankle Society (AOFAS) hallux/forefoot scores were used for patient satisfaction.Results:Preoperative mean values of HVA, IMA, and PPA of 32.8 degrees, 14.6 degrees, and 7.52 degrees, respectively, improved to 10.7 degrees, 6.0 de...
