Abstract
Introduction: Scarf osteotomy is a zosteotomy of 1st metatarsal and is proposed to correct anatomical and functional deformities of hallux valgus. This procedure allows early ambulation without cast and early return of function. However, this is a technically demanding procedure. This study was conducted to evaluate clinical and paedobarographic results following this procedure in a district general hospital. Method and materials: We prospectively collected the data from 71 feet in 54 patients. We collected the AOFAS scores preoperatively, 3 and 6 months. Hallux vagus, 1–2 intermetatarsal angles and sesamiod subluxation were measured from weight bearing radiographs taken preoperatively, 6 weeks and 6 months. We evaluated the forefoot function using peak pressure, force time integral and pressure time integral parts of paedobarographs (Musgrave) preoperatively, 3 and 6 months. Results: Total AOFAS score increased from 43.11 preoperatively to 84.96 at 3 months postoperatively (p< 0.0001, 95% CI of 44.5 to 35.5). The hallux valgus angle decreased from 30.1 to 9.92 at 6 weeks post operatively (p< 0.0001, 95% CI of 22.21 to 18.27). The mean peak pressure under the 1st metatarsal head was reduced from 3.09 (95% CI 2.49 Ð3.70) to 2.25 (95% CI1.80–2.71) at 6 months. The mean peak pressure under the 2nd metatarsal head was reduced from 6.29(95% CI 5.44–7.13) to 5.01 (95% CI 3.98–6.05) at 6 months. Force time and Pressure time integrals also showed similar changes. Conclusions: Scarf osteotomy produced improvement in the postoperative scores, radiological angles and forefoot pressures. In conclusion, scarf osteotomy is a versatile and reliable procedure in the management of hallux valgus.
