myotomy

Muscle cutting is used for the surgical treatment of the palm palm malformation. The palm of the thumb is malformed, also known as the thumb adductor deformity, or the claw-shaped thumb deformity. This malformation prevents the item from entering the palm of the hand and prevents the thumb from assisting other fingers in grasping the item. The reason for the deformity of the palm of the thumb is that the flexor hallucis longus, the flexor hallucis longus muscle, the abductor muscle and the dorsal muscle of the first interosseous muscle are in a paralyzed state, and the muscles of the extensor hallucis longus, the extensor pollicis longus and the adductor muscle of the thumb are weak. The extensor of the longus extensor muscle also plays a role in the formation of the adductive deformity of the thumb during the relaxation period. Treatment of diseases: cerebral palsy Indication Muscle cutting is applied to the deformity of the palm of the thumb. Surgical procedure 1. Make an incision along the edge of the fish line in the palm, but avoid the damage of the median nerve to the branch of the adductor muscle or the innervation of the adductor muscle. 2, pull the thumb long flexor tendon, and peel off the thumb muscle on the third metacarpal. From the deep transverse ligament of the wrist, the callus of the thumb abductor muscle was cut about 2/3 and all the flexor hallucis of the thumb and the palm of the thumb. 3, from the first metacarpal dorsal side of the incision, close to the first metacarpal to cut the first dorsal interosseous muscle.
