Summary: This study evaluated the short-term effectiveness of Scarf osteotomy and Akin osteotomy combined with soft tissue procedures for hallux valgus (bunion) associated with mild to moderate metatarsus (big toe) adductus (deformity).

Conclusion: The short-term effectiveness of Scarf osteotomy and Akin osteotomy combined with soft tissue procedures for hallux valgus (bunion) associated with mild to moderate metatarsus (big toe) adductus (deformity) is satisfactory, and no correction is required for metatarsal adductus.

Abstract

Objective: To evaluate the short-term effectiveness of Scarf osteotomy and Akin osteotomy combined with soft tissue procedures for hallux valgus associated with mild to moderate metatarsus adductus.

Methods: The clinical data of 30 patients (48 feet) who were diagnosised hallux valgus associated with mild to moderate metatarsus adductus and treated by Scarf osteotomy and Akin osteotomy combined with soft tissue procedures between February 2013 and May 2015 were analyzed retrospectively. There were 2 males (2 feet) and 28 females (46 feet) with an average age of 29.4 years (range, 18-50 years). The disease duration was 3-12 years (mean, 6.1 years). The degree of metatarsal adductus was assessed by Sgarlato's measurement and Yu et al classification criteria, and the degree of metatarsal adductus was mild in 20 feet and moderate in 28 feet. Preoperative X-ray examination showed that the hallux valgus angle (HVA) was (39.4±5.6)°, the first-second intermetatarsal angle (1-2IMA) was (15.2±3.5)°, the metatarsus adductus angle (MAA) was (21.2±3.7)°. The American Orthopaedic Foot and Ankle Society (AOFAS) score was 51.7±10.0, and visual analogue scale (VAS) score was 4.9±2.7 before operation. Postoperative complications and the union time of osteotomies were recorded. At last follow-up, the HVA, 1-2IMA, and MAA were measured on X-ray films, and the AOFAS scores and VAS scores were recorded, then compared them with preoperative ones. Roles - Maudsley score was used to investigate patients' satisfaction.

Results: All the incisions healed by first intention. Thirty patients were followed up 24-27 months (mean, 26.4 months). Three patients (4 feet) occured metatarsalgia, and the pain relieved after treated by Custom-Made Orthotics. All the osteotomies were unoin, the healing time was 2-4 months (mean, 2.7 months). At last follow-up, the HVA and the 1-2IMA were (13.2±3.1)° and (5.1±2.3)°, respectively, showing significant differences when compared with preoperative ones ( t=14.606, P=0.000; t=22.356, P=0.000); the MAA was (21.0±3.4)° and there was no significant difference when compared with preoperative one ( t=0.789, P=0.434). The AOFAS and VAS scores were 91.8±7.5 and 1.1±1.0, respectively, showing signifiant differences when compared with preoperative ones ( t=13.787, P=0.000; t=14.781, P=0.000). Satisfaction survey showed that 28 patients were very satisfied and satisfied (93.3%), and 2 cases were not satisfied (6.7%).

Conclusion: The short-term effectiveness of Scarf osteotomy and Akin osteotomy combined with soft tissue procedures for hallux valgus associated with mild to moderate metatarsus adductus is satisfactory, and no correction is required for metatarsal adductus.
