Winged Scapula can be caused by a condition known as Neuralgic Amyotrophy. It is thought to be autoimmune in origin and causes damage to nerves at the root. Most common first symptom is pain in shoulder and loss of strength and muscle wasting. Due to shoulder joint problems, TOS can develop as part of this, but it is not a cause. NA can also impact most other areas of the body.
