These nerves originate in the fifth, sixth, seventh and eighth cervical (C5–C8), and first thoracic (T1) spinal nerves, and innervate the muscles and skin of the chest, shoulder, arm and hand. [1] [2] [3] Brachial plexus injuries can occur as a result of shoulder trauma (e.g. dislocation [4]), tumours, or inflammation, or obstetric.
Shoulder trauma during motor vehicle collisions is another common cause of brachial plexus avulsions. [22] Detachment of the nerves can cause pain and loss of function in the arms, shoulders, and hands. Neuropathic pain can be treated with medication, but it is only through surgical reattachment or nerve grafts that function can be restored. [22]
Abrasions on elbow and lower arm. The elbow wound will produce a permanent scar. A first-degree abrasion involves only epidermal injury. A second-degree abrasion involves the epidermis as well as the dermis and may bleed slightly. A third-degree abrasion involves damage to the subcutaneous layer and the skin and is often called an avulsion.
The cause of death was listed as three gunshot wounds to the back, abdomen and chest. All wounds were specified as gunshot entry from the back (posterior left shoulder, left upper back and right lower back). [2] [39]
A SLAP tear or SLAP lesion is an injury to the superior glenoid labrum (fibrocartilaginous rim attached around the margin of the glenoid cavity in the shoulder blade) that initiates in the back of the labrum and stretches toward the front into the attachment point of the long head of the biceps tendon.
A strain is a type of acute injury that occurs to the muscle or tendon. Similar to sprains, it can vary in severity, from a stretching of the muscle or tendon to a complete tear of the tendon from the muscle. Some of the most common places that strains occur are in the foot, back of the leg (hamstring), or back. [2]

For instance, axillary nerve palsy can occur after there is blunt trauma in the shoulder area without any sort of dislocation or fracture. [5] Examples of this blunt trauma may include: being hit by heavy an object, falling on shoulder, a strong blow while participating in boxing, or motor vehicle accidents. [5]
