From: Neuroanatomical Basis of Clinical Neurology [2019] Injury of axillary nerve (axillary neuropathy) is a condition that can be associated with a surgical neck of the humerus fracture. The surgeon should also be aware that such injuries are part of the complication profile of both open and arthroscopic surgery involving the shoulder. In this article, we shall look at the applied anatomy of the nerve - its anatomical course, motor functions and cutaneous innervation. These are the musculocutaneous nerve, the axillary nerve, the radial nerve, the median nerve and the ulnar nerve. Aug 14, 2023 · Peripheral nerve injury can vary wildly in severity and presentation, ranging from mild soreness to severe muscle weakness.

This can happen when you sleep on an outstretched arm, have compression in your armpit from crutches or have a humerus bone fracture. Furthermore, it can be injured during luxation shoulder joint, or during an injury to the deltoid muscle (blunt impact on the shoulder). It can also be associated with a dislocated shoulder [1] or with traction injury to the nerve, which may be caused by over-aggressive stretching or blunt trauma that does not result in fracture or dislocation. An early diagnosis and treatment can result in a better prognosis of the condition. The axillary nerve is vulnerable as it passes around the humerus and through the quadrilat-eral space of the posterior shoulder. What is axillary nerve dysfunction (AND)? Axillary Nerve Palsy Axillary nerve injury is an uncommon condition which results in weakness of the deltoid muscle and numbness on the side of the shoulder. reported nearly eleven-fold increased risk of neurologic injury, with EMG changes most commonly affecting the axillary nerve, when the arm is lengthened during reverse arthroplasty. Apr 17, 2019 · Procedures that place the axillary nerve at risk include the lateral, deltoid-splitting approach to the shoulder and during an inferior capsular release/suturing for shoulder arthroplasty procedures or labral repair, respectively.

Nerves carry signals from the brain to maintain and communicate with skeletal muscles, telling them to contract when necessary. The radial nerve comprises the C5 to T1 nerve roots, which arise from the posterior segment of the brachial nerve plexus. These may be caused by over stretching the shoulder joint or direct trauma to the area. It can occur at any age. The usual causes are: Direct injury Excessive stress or damage to the axillary nerve, which serves the deltoid muscles and skin of the shoulder, causes axillary nerve palsy.
