Camptodactyly is an isolated congenital flexion deformity of the proximal interphalangeal (PIP) joint. Surgical experience with 16 patients (18 fingers) between June 1983 and December 1994 is reported. Skin, fascia (retinaculum cutis), tendon sheaths, flexor digitorum superficialis tendon, lumbricals and interossei (particularly the lateral bands), joint surfaces, neck of the proximal phalanx, and central slip insertion were involved in all cases, although the degree of involvement can vary. Surgery must address all of these structures. Postoperative splinting is important. Fifteen patients had good or excellent results after surgery, with a mean gain in motion of 57 degrees (range, 0 degrees-90 degrees). Surgery should be aimed at prevention of progressive deterioration and is probably not indicated in minor degrees of the deformity. Surgery should be reserved for patients with a preoperative PIP joint contracture of more than 60 degrees.
先天性屈曲指是一种孤立的近端指间关节（PIP）先天性屈曲畸形。本文报告了1983年6月至1994年12月期间对16例患者（18根手指）的手术经验。所有病例均累及皮肤、筋膜（皮肤支持带）、腱鞘、指浅屈肌腱、蚓状肌和骨间肌（尤其是外侧束）、关节面、近节指骨颈部和中央束附着处，尽管受累程度有所不同。手术必须处理所有这些结构。术后夹板固定很重要。15例患者术后效果良好或极佳，平均活动度增加57度（范围为0度至90度）。手术应旨在预防病情进行性恶化，对于轻度畸形可能无需手术。手术应仅用于术前近端指间关节挛缩超过60度的患者。
