Long Thoracic Nerve Injury

Entrapment occurs secondary to falls on the shoulder or with chronic repetitive motion motion such. This nerve innervates the serratus anterior muscle which is important for scapular stabilization protraction and rotation during shoulder abduction.

The most easily observed manifestation related to the long thoracic nerve palsy is winging of the scapula a protrusion of the scapula from the back.

Long thoracic nerve injury

. Anatomy of Long Thoracic Nerve LTN The LTN provides the link between our brain and the muscle. Injury to long thoracic nerve is common secondary to compression in the armpit region especially with tight bandages plaster casts splints or poorly adjusted crutches. Injury to the long thoracic nerve occurs acutely from a blow to the shoulder or with activities that involve chronic repetitive traction on the nerve eg tennis swimming.

Some of the natural reasons for thoracic spine nerve damage include a herniated disc thoracic radiculopathy or a narrowing of the foramen. Each vertebra in the spine is associated with the nerves that are in that section of the spinal cord and it is the nerve damage that can cause debilitating injury or pain. Patients are mainly adults which are.

External reasons for nerve damage. Long Thoracic Nerve impingement under the inferior angle of the scapula during general anesthesia or during passive abduction of the arm Signs and Symptoms. The long thoracic nerve is susceptible to damage causing backpack palsy due to its long and superficial course either from direct trauma or stretching of the nerve.

The long thoracic nerve may be injured by neck and thoracic trauma during motor vehicle accidents sports injuries or surgical procedures of the arm neck or chest. If the nerve does not function then the affected scapula will lift off the chest when force is applied to that shoulder unit. It also has a complex course going from the spinal cord to the neck passing through the armpit axilla and eventually lying on the side of the chest wall.

Damage to the nerve may also occur during surgical procedures including thoracoplasty axillary nodal clearance mastectomy and resection of the first rib. Long Thoracic Nerve Injuries Long thoracic nerve injury is another peripheral-nerve shoulder injury seen in football players and can be quite disabling. A case of long thoracic nerve palsy LTNP corresponds to a weakened serratus anterior muscle.

The test for identifying a long thoracic nerve injury is the serratus wall test. Nerves are classified into three groups. It is akin to the wiring of the muscle.

The nerves can be damaged for various reasons. Nerve injury can result is loss of sensation or problem with your muscles. The long thoracic nerve follows a long an tortuous course from the neck to the serratus anterior muscle.

Long Thoracic Nerve Injury Caused by Overhead Weight Lifting Leading to Scapular Dyskinesis and Medial Scapular Winging Scapular winging represents a rare phenomenon that most commonly results from nerve damage to either the long thoracic nerve spinal accessory nerve or less commonly the dorsal scapular nerve. The long thoracic nerve LTN is a motor nerve that innervates the serratus anterior muscle. Long Thoracic Nerve.

Scapular winging medial translation of the scapula inferior angle rotates towards midline and prominence of the vertebral border which becomes more prominent with pushing forward against resistance. This always leads to pain a condition called peripheral neuropathy. Injury to this nerve may lead to insufficiency in serratus anterior function which manifests as scapular winging.

It is prone to injury as it is much more vulnerable than many of the other nerves of the brachial plexus. To understand how the nerves repair and regenerate you need to understand the types of nerve injuries.
