负责琴键和尖端捏的主要内在肌肉是拇内收肌、第一骨间背侧肌和拇短屈肌。许多情况都会导致其功能障碍。非手术治疗包括补偿拇长伸肌和拇长屈肌的锻炼以及使用适应性装置，例如更大的握力。手术治疗包括肌腱转移和关节融合。最常见的肌腱转移手术包括将桡侧腕短伸肌转移至拇内收肌或将拇长展肌转移至第一背侧骨间肌。两者都需要使用延伸肌腱移植物。在关节不稳定或关节病的情况下，可能需要单独或联合进行拇指和食指 MP 或 IP 关节的关节融合术。
The primary intrinsic muscles responsible for key and tip pinch are the adductor pollicis, first dorsal interosseous and flexor pollicis brevis muscles. Numerous conditions can lead to their dysfunction. Non-operative treatment consists of exercises of the compensating extensor pollicis longus and flexor pollicis longus muscles and use of adaptive devices, such as larger grips. Operative treatments include tendon transfers and joint fusions. The most common tendon transfer procedures include transfering of the extensor carpi radialis brevis to the adductor pollicis muscle or transfering of the abductor pollicis longus to the first dorsal interosseous muscle. Both require use of extension tendon grafts. In cases of joint instability or arthrosis, arthrodesis of the thumb and index finger MP or IP joints, alone or in combination, may be indicated.
