[Study of conductivity of the motor fibers of the ulnar nerve with respect to intensity, localization and diagnosis of peripheral nerve disease. I. General and morphologic observations on the affected area of the ulnar nerve with emphasis on the elbow region and causes of the disease].
The introductory part deals with a great community impact of ulnar nerve damage and its high incidence. From peripheral nerves, this ulnar is the most frequently exposed to injuries and impresses. The impressory damage occurs mainly in elbow region. Anatomic peculiarities of ulnar nerve are scrutinized concerning with more connective tissue presence on its cutting section comparably to the other upper limb nerves. Frequent innervative deviations are referred to especially in ulnar and median nerve regions in the course of ulnar nerve branching. Also three types of anastomoses are listed between the both nerves which are important as to the clinical pattern in damages and for electrophysiologic diagnosing. From the clinical tests, those of rare use are emphasized (test of crossed fingers, palmaris brevis sign, Mumenthaler's sign, ulnar test). The last part deals in detail with anatomic, functional and clinical problems of ulnar nerve in elbow area. Its biomechanic relations in the cubital tunnel are elucidated as well as etiopathogenetic factors of neural damage in this area (traction and compressive theories and hypermobility of the nerve etc.). The most frequent causes of ulnar injuries are reviewed. The present work is of introductory value for those dealing mainly with electrophysiologic problems of both sensitive and motoric neural injuries varying in the intensity, location and diagnosis.
