Seventy-eight chevron osteotomies augmented by internal fixation with self-reinforced polyglycolide pins, 2 mm in diameter, were performed in 60 patients suffering from a painful hallux valgus. The mean metatarsophalangeal angle was 31 degrees, and there was a metatarsus primus varus varying from 10 degrees to 20 degrees. The average follow-up time was 14 (range, 12 to 31) months. No postoperative redisplacement or disturbance of healing of the osteotomy was observed, but recurrence of hallux valgus occurred in 8 feet (10%), each initially with a moderate to severe hallux valgus. Some pain at the first metatarsophalangeal joint during physical activity remained in 12 feet (15%). There was a mean shortening of 2.5 mm of the first metatarsal bone, and the most significant shortening was associated with pain in the forefoot. The metatarsophalangeal joint motion was not decreased. The subjective overall result was excellent or good in 75% of the patients. Because of the biodegradability of the implants used, no secondary procedures to remove the implants were necessary.
对60例患有疼痛性拇外翻的患者进行了78例采用直径2毫米的自增强聚乙醇酸针内固定的V形截骨术。平均跖趾角为31度，第一跖骨内翻在10度至20度之间。平均随访时间为14（范围12至31）个月。未观察到截骨术后的再移位或愈合障碍，但8只足（10%）出现了拇外翻复发，每只足最初均为中度至重度拇外翻。12只足（15%）在体力活动时第一跖趾关节仍有一些疼痛。第一跖骨平均缩短2.5毫米，最明显的缩短与前足疼痛有关。跖趾关节活动度未降低。75%的患者主观总体结果为优或良。由于所使用植入物的生物可降解性，无需进行二次手术取出植入物。
