Akin combined Scarf osteotomies for moderate and severe hallux valgus / 天津医药

ABSTRACT

Objective To study the clinical efficacy of Akin combined Scarf osteotomies for moderate and severe hal?lux valgus. Methods Thirty-nine (58 feet) patients received Akin combined Scarf osteotomies, in which 12 patients (16 feet) with moderate hallux valgus received the single scarf osteotomy. Hallux valgus angle (HVA), intermetatarsal angle (IMA), tibial sesamoid position and American orthopedic foot and ankle society score (AOFAS) were measured and compared before and after operation respectively. Results All operations were successfully completed patients were followed up for 8-22 months. The mean operation time was (55.0±6.8) min. The amount of intraoperative bleeding was 3-20 mL with an aver?age of (11.0±5.4) mL. All patients were healed except for a delayed union of Akin on a severe hallux valgus patient. Two cas?es (2 feet) were found inflammation in surgical incision. Two cases (2 feet) were found numbness in dorsal medial side of hal?lux, which was considered nerve damage and improved in 3-5 months. There was no recurrence of hallux valgus in the peri?od of following up. After surgery, HVA (14.1°±5.3°), IMA (7.7°±3.8°) and tibial sesamoid position (2.58±0.61) were signifi?cantly decreased compared with those before operation (39.6° ± 6.8° , 18.7° ± 5.4° and 4.87 ± 0.59, P<0.05). AOFAS score (84.4±8.7) was significantly higher after surgery than that before surgery (37.3±9.5, P<0.05). Conclusion Akin combined Scarf osteotomies can achieve a excellent therapeutic effect for moderate and severe hallux valgus with very few complica?tions and recurrence, which is worth for clinical application.
