The superior component originates from the first and second ribs and inserts into the superior medial angle of the scapula [ 4 long thoracic nerve palsy exercises to lose weight, 8 ]. As such, it is generally considered a salvage operation after failure of other surgical procedures [ 873 ], or reserved for patients with generalized shoulder weakness such as facioscapulohumeral dystrophy [ 545574 ]. With conservative treatment, most LTN injuries resolve on average within nine months, however, recovery can take anywhere from six to 24 months 1,7. Diagnosis is easily made upon visible inspection of the scapula, with serratus anterior paralysis resulting in medial winging of the scapula. Together, this scapula and shoulder unit allows the arm to move forward with the activation of the long thoracic nerve.

He created the Posture Direct blog in with the goal of helping as many people fix their own posture. In contrast, trapezius paralysis results in exaggerated lateral winging upon active abduction.

To improve strength and overhead work, strengthening exercise of all shoulder girdle muscles, including the trapezius, should be implemented and avoidance of overstretching the serratus anterior should be continued. My question is, if my serratus anterior is weak and my scapula is coming off my rib cage when I try and retract, would this inhibit my trapezius muscle from working properly? Nerve recovery depends on the nature of the injury.

Repetitive movements can also cause injuries. Question Importance. The epineurium was released sharply with microsurgical instruments and technique under high magnification.
