The scapula shoulder blade is the largest bone of the shoulder complex and has the greatest number of muscles attached to it. These muscles both stabilise the arm to the body and move the arm around in space. All these muscles act at the same time sometimes and oppose each other at other times, but work together like a well trained team to allow the arm to move in space. If any of these muscles are not working in the right way at the right time this leads to a break in the rhythmic motion of the scapula.
A winging scapula is a shoulder injury or condition in which the scapula or shoulder blade sticks out at the back, particular when lifting the arm up or pushing against something. Often patients complain of pressure on the shoulder blade from the back of their chair when sitting. If the long thoracic nerve is damaged or bruised it can cause paralysis of the serratus anterior muscle and winging of the scapular or shoulder blade. Damage to the nerve can be caused by a contusion or blunt trauma of the shoulder, heavy weight lifting, repetitive throwing, traction of the neck or can also sometimes follow a viral illness.
CASE STUDY: THERMOPLASTIC SCAPULOTHORACIC ORTHOSIS FOR TREATMENT OF WINGING SCAPULA
Winging scapula is a rare condition that can be painful and debilitating to the upper extremity involved1. This condition can affect the functional ability of the upper extremity, resulting in loss of range of motion, decreased power, and pain. The thermoplastic scapulothoracic orthosis offers total contact and provides anterior-posterior compressive forces to stabilize the winging scapula. This design provides a semi-rigid structure that is lightweight and allows user adjustability. The study highlights the potential applicability of the custom thermoplastic scapulothoracic orthosis in the categories of pain, active range of motion at the shoulder, and overall self-reported activities of daily living.
University interested in working with PTFE? My current understanding is that there are no videos on the NPTE, but there are frequently pictures that describe and demonstrate a series of questions. In order to help you prepare for this, I shot this brief video of a patient with bilateral shoulder pain and noticed a few things.
