Peripheral nerves are responsible for somatic (voluntary) and autonomic (involuntary) functions. The primary functions of the peripheral nervous system are to receive general sensations (touch, pressure, temperature, and pain), and special sensations (sight, smell, taste, and hearing), integrate sensory input from the entire body, and generate a response[1]. Peripheral Nerve Injury can ...
Radial nerve injuries are associated with the path it travels close to the humerus. Mechanisms of injury can be humerus fracture, a direct blow or sustained pressure (i.e. from incorrect use of a crutch). Motor function of the triceps are usually preserved as they are innervated superiorly whereas wrist and digit extensors are often paralysed ...
Pathological Process. Peripheral nerve injuries have numerous causes including traumatic injuries; infections; metabolic problems ( one of the most common causes is diabetes mellitus); inherited causes; exposure to toxins; tumors; iatrogenic causes. [2] Watch the below to grasp the concepts of nerve damage and repair.
Aug 14, 2023 · The radial nerve stems from the posterior cord of the brachial plexus and supplies the upper limb. It also supplies the triceps brachii muscle of the arm, the muscles in the posterior compartment of the forearm (also known as the extensors), the wrist joint capsule, and aspects of the dorsal skin of the forearm and hand. The radial nerve proper innervates[1]:

Aug 29, 2024 · Treatment can involve observation, repair, tendon transfers or nerve grafting depending on the acuity, degree of injury, and mechanism of injury. Epidemiology.

1. Introduction. Peripheral nerve injuries are frequently encountered in clinical practice and often result in functional disability. In the past, due to poor understanding of pathophysiology, the results of nerve repair were unpredictable. Sunderland 1 in 1945 described the microsurgical techniques which improved the results of nerve repairs.
