16 patients (75% women) were operated for a claw nail involving one of the three middle fingers. In 14 cases out of 16, a traumatic amputation, treated by directed healing in 60% of cases, was responsible for the deformity. The average loss of bone substance was 49% (range: 0-90%). The average shortening was 5 mm. The loss of substance was repaired by a local flap in 14 cases. Two early recurrences led to one failure and one good result after a second recession flap. One case of arthritis of the distal interphalangeal joint and one case of septic necrosis of the nail bed were also observed. Eleven subjects were reviewed with a mean follow-up of 4 years (1-7 years). The range of movement of the distal interphalangeal joint was always normal. The pinch force and the growth of the nail were normal in 75% of cases. The finger was cumbersome in one half of cases and 60% of patients complained of pain. Recurrences were observed in 50% of cases and the patients were disappointed in 64% of cases. This is a minor operation in terms of vascular elements, but it is associated with a high rate of recurrence and leaves a short finger. Its indications should be limited to losses of bone substance less than 50%.
16例患者（75%为女性）因累及中指中的一根手指的爪形指甲接受手术。16例中有14例，创伤性截肢（60%的病例采用直接愈合治疗）是导致畸形的原因。骨质平均损失49%（范围：0 - 90%）。平均缩短5毫米。14例通过局部皮瓣修复骨质损失。2例早期复发，其中1例在二次退缩皮瓣术后失败，1例效果良好。还观察到1例远侧指间关节关节炎和1例甲床化脓性坏死。11名受试者接受复查，平均随访4年（1 - 7年）。远侧指间关节活动范围始终正常。75%的病例捏力和指甲生长正常。一半的病例手指活动不便，60%的患者抱怨疼痛。50%的病例出现复发，64%的患者感到失望。就血管因素而言，这是一个小手术，但它与高复发率相关，且会导致手指短小。其适应证应限于骨质损失小于50%的情况。
