Carpal tunnel and ulnar tunnel neurodecompression

Carpal ulnar tunnel syndrome refers to the symptoms and signs of sensory and motor dysfunction caused by the compression of the ulnar nerve in the ulnar bony fibrous duct of the wrist due to any factor. The carpal ulnar tube, also known as the Guyon tube, is located on the ulnar side of the anterior wrist region and is composed of the transverse carpal ligament and the distal portion of the palmar ligament. The ulnar artery, ulnar vein, and ulnar nerve pass through the tube. The ulnar nerve is divided into the deep and superficial branches, that is, the motor branch and the sensory branch. The upper carpal canal is composed of the proximal edge of the pea bone, the carpal palmar ligament, and the transverse carpal ligament; the lower carpal canal is composed of the carpal palmar ligament, the palmar short muscle and aponeurosis, the bean hook ligament, and the ulnar wrist flexor And the tendons of the medial hand muscle group.
