Function of flexor carpi ulnaris?

summary

Flexor carpi ulnaris instead of extensor digitorum and extensor pollicis longus is used in the treatment of spastic paralysis hand deformity. Spastic cerebral palsy caused by hand deformity, treatment is more difficult, surgery can only solve part of the function. It is mainly based on patient training of spastic muscles, physiotherapy, manual correction of deformity and intelligence training. It is suggested that for every patient who needs hand surgery, it is best to observe continuously for more than 6 months. During this period, splint brace should be used as far as possible to correct deformity and train function. Before operation, comprehensive consideration should be given to patient's age, degree of paralysis and contracture, hand deformity, hand muscle dysfunction and sensation, patient's intelligence and subjective effort, degree of involvement of other joints, and patient's and family's attitude towards operation.

Function of flexor carpi ulnaris?

Starting point: medial epicondyle of humerus, forearm fascia and olecranon. 2 stop: pea bone, second metacarpal base. Function: make the radiocarpal joint flexion, participate in the radiocarpal joint adduction and elbow joint flexion. As early as 1970s, flexor carpi ulnaris muscle transposition was used to reconstruct elbow flexion in foreign countries. Objective: To investigate the distribution of intramuscular nerve branches and muscle architecture of flexor carpi ulnaris in the ulnar and radial half of flexor carpi ulnaris, and to reveal the morphological characteristics of flexor carpi ulnaris, Objective to provide morphological basis for hemi muscle transposition in orthopedic surgery, and to provide new ideas for the selection of autologous skeletal muscle transposition.

Methods: the general shape of flexor carpi ulnaris of 20 sides was observed and the number of flexor carpi ulnaris was measured; ② In order to observe the distribution of intramuscular nerves, the modified Sihler's staining method was used to stain the intramuscular nerves of 10 flexor carpi ulnaris muscles; ③ The flexor carpi ulnaris was divided into ulnar half and radial half along the long axis of the tendon. Results: ① the ulnar nerve trunk sent out two nerves into the ulnar and radial half of flexor carpi ulnaris muscle respectively, and sent out several nerve branches in the corresponding half muscle; But the nerve branches in ulnar and radial half of the muscle are located in the intramuscular tendon plate.

Ulnar nerve block by palmar puncture of flexor carpi ulnaris tendon has a low incidence of ulnar nerve and ulnar artery injury. Compared with the other two nerve block methods, the distance between puncture needle and ulnar nerve and ulnar artery was significantly different. This suggests that ulnar nerve block via palmar approach may be a safer method.

matters needing attention

The applied anatomy and clinical significance of the flexor carpi ulnaris are described above. Its application and clinic have made great achievements in the medical history of our country. The ulnar nerve block of the wrist is very important for the treatment of hand diseases and hand injuries. The safe injection can not be ignored because of the permanent injury of blood vessels and nerves caused by intraneural or intravascular injection.
