[Restoration of discrimination sensitivity after suturing nerves of the upper extremity].

Having examined the discriminational sensitivity with Weber's dividers in 244 patients 1-10 and more years after epineural suture of the median, ulnar and palmar digital nerves, the authors established that this type of sensitivity restored slowly, incompletely and rarely. Discrimination of two points was better restored after suture of the palmar digital nerves, it was worse after suture of the median nerve and was the worst after suture of the ulnar nerve. The factors adversely affecting the restoration of discriminational sensitivity included a high level of damage (upper arm, the upper third of the forearm) and a considerable delay with surgery.
