Short fourth metatarsals were observed in 102 patients, often bilaterally. Forty-six of these patients were treated by variations on Jinnaka's bone-lengthening method--that is, interposing a spindle-shaped bone graft within the metatarsophalangeal joint. We examined twenty-six patients clinically and roentgenographically after a follow-up averaging 11.4 years. Satisfactory results were obtained in 74.4 per cent.
在102例患者中观察到第四跖骨短小，常常为双侧性。其中46例患者采用了Jinnaka骨延长法的不同术式，即在跖趾关节内植入纺锤形骨移植物。我们对26例患者进行了平均11.4年的随访，进行了临床和X线检查。结果显示74.4%的患者取得了满意疗效。
