Six lesser metatarsal lengthening procedures were performed in three patients using a miniature external fixator to perform distraction osteogenesis. The metatarsals were lengthened an average of 15.5 mm. The external fixator was left in place for an average of 15.5 weeks, with additional time in a cast or cast shoe. Complications included five occurrences of infection, two cases of premature healing of the osteotomy, one nondisplaced fracture through the new bone formation, and hypertrophic granulation at a pin site. While all metarasals were successfully lengthened, two rays (one patient) had symptomatic stiffness at the metatarsophalangeal joint with continued metatarsalgia.
对三名患者进行了六次小趾跖骨延长手术，使用微型外固定器进行牵张成骨。跖骨平均延长了15.5毫米。外固定器平均留置15.5周，之后还需在石膏或石膏鞋中额外固定一段时间。并发症包括5次感染、2例截骨过早愈合、1例通过新骨形成部位的无移位骨折以及1处针道的肥厚性肉芽组织。虽然所有跖骨均成功延长，但有两条跖骨（一名患者）在跖趾关节处出现症状性僵硬，并伴有持续性跖痛。
