Splints and activity modification help limit repetitive elbow extension, forearm pronation, and wrist flexion. Table 2 summarizes specific physical examination findings and treatment options associated with each nerve.1338, Brachial Plexus. The orthosis can help with grasp and release during day-to-day activities while awaiting nerve recovery. At the wrist, the superficial radial nerve is susceptible to injury by compression because it runs superficially to the flexor retinaculum. Appointments 866.588.2264 Appointments & Locations Request an Appointment Function Anatomy Kellog community college. It also provides sensation to the back of the hand. Spinal Accessory Nerve. Occupational risks: Jobs that require repetitive motion and awkward postures or working positions may increase the risk of radial nerve palsy. [QxMD MEDLINE Link]. Compression of the superficial radial sensory nerve (RSN) in the distal forearm is best treated conservatively by eliminating any possible external compression, decreasing inflammation by utilizing a thumb spica forearm-based splint (allowing interphalangeal motion), and administering anti-inflammatory medications and cortisone injections. This condition may go away over time as accompanying injuries heal, cysts or tumors are removed, or awkward postures are corrected. ), ISBN: 978-953-51-0407-0, InTech, Available from: Dr. Simon Freilich. Proposed mechanisms are traction, compression, or direct trauma to the brachial plexus or cervical nerve root (e.g., leading with the shoulder during a tackle in football).20 The most common distribution is the C5 and C6 myotomes and dermatomes.

Scand J Plast Reconstr Surg Hand Surg. <> Please read Classification of Peripheral Nerve Injury as an introduction to this page. stream Other injuries: Broken bones, joint dislocations, significant bruises and injuries requiring the use of crutches can increase a persons risk for radial nerve palsy. [19] Aerobic activity should also be encouraged ( aiming for 30 minutes 4 times a week) for its known health benefits. Muscle or nerve injections. The aim of this work is to review the interplay of psychosocial factors and peripheral nerve lesions. match muscle strength. In the absence of traumatic injury, initial treatment of nerve injuries should be conservative and include patient education, physical therapy, and activity modification. In the relearning of functional tasks, the brain is utilized to regain visio-tactile and audio-tactile interaction.

General anesthesia without complete paralysis is preferred for proximal lesions so that intraoperative nerve stimulation may be utilized. 2nd ed. Treatment of radial nerve palsy may include: Your physician may recommend prescription or over-the-counter medication to decrease pain associated with radial nerve palsy. 3 0 obj Thomsen NO, Dahlin LB. These include, A consequence of denervation is muscle atrophy and functional deficits. It is designed to provide safe, practical guidance in the screening, diagnosis and management of complications related to long term high dose steroid therapy initiated in primary or secondary care. 234. hbbd```b``! The distal margin of the supinator is identified, and the fascia is incised between the extensor carpi radialis longus and brevis and the extensor digitorum communis.
