In five of six cases of camptodactyly in which an abnormality of the flexor tendon was examined at operation, the flexor digitorum superficialis tendon was hypoplastic and there was no continuity of the normal tendon between the muscle belly and bony insertion. The proximal end of the flexor digitorum superficialis tendon was attached to the palmar aponeurosis and the flexor tendon sheath of the ring finger in two patients, to the palmar aponeurosis in one, to the undersurface of the transverse carpal ligament in one and to the flexor tendon sheath of the ring finger in one. The tenodesis effect of the abnormal tendon of the flexor digitorum superficialis is considered to play an important role in the cause and rapid increase of the deformity of camptodactyly.
在6例先天性屈曲挛缩畸形病例中，有5例在手术中检查了屈肌腱异常情况，其中指浅屈肌腱发育不全，肌腹与骨附着点之间无正常肌腱连续性。在2例患者中，指浅屈肌腱近端附着于掌腱膜和环指指屈肌腱鞘；1例附着于掌腱膜；1例附着于腕横韧带下面；1例附着于环指指屈肌腱鞘。指浅屈肌异常肌腱的动力固定作用被认为在先天性屈曲挛缩畸形的病因及畸形迅速加重中起重要作用。
