A winged scapula (scapula alata) is a skeletal medical condition in which the shoulder blade protrudes from a person's back in an abnormal position. In rare conditions it has the potential to lead to limited functional activity in the upper extremity to which it is adjacent. It can affect a person's ability to lift, pull, and push weighty objects.
There are several options of treatment when iatrogenic (i.e., caused by the surgeon) spinal accessory nerve damage is noted during surgery. For example, during a functional neck dissection that injures the spinal accessory nerve, injury prompts the surgeon to cautiously preserve branches of C2, C3, and C4 spinal nerves that provide supplemental innervation to the trapezius muscle. [3]
The dorsal scapular nerve is a branch of the brachial plexus, usually derived from the ventral ramus of cervical nerve C5. It provides motor innervation to the rhomboid major muscle, rhomboid minor muscle, and levator scapulae muscle. Dorsal scapular nerve syndrome can cause a winged scapula, with pain and limited motion.
Injury to the nerve can result in shoulder girdle depression, atrophy, abnormal movement, a protruding scapula, and weakened abduction. [5] Weakness of the shoulder girdle can lead to traction injury of the brachial plexus. [10] Because diagnosis is difficult, electromyogram or nerve conduction studies may be needed to confirm a suspected ...
A winged scapula (left) Left scapula, anterior surface. Anatomic neck: red, Surgical neck: purple. Because of its sturdy structure and protected location, fractures of the scapula are uncommon. When they do occur, they are an indication that severe chest trauma has occurred. [15] Scapular fractures involving the neck of the scapula have two ...
Scapular winging is amenable to surgical correction, namely operative scapular fixation. Scapular fixation is restriction and stabilization of the position of the scapula, putting it in closer apposition to the rib cage and reducing winging. Absolute restriction of scapular motion by fixation of the scapula to the ribs is most commonly reported ...
Orthopedic surgery address foot deformities, scoliosis, Achilles tendon contractures, and winged scapula. Winged scapula can be addressed with either scapulopexy or scapulothoracic fusion. [1] Circumstances to avoid include extremes of body weight, bone fractures, and prolonged immobility. [1]
Symptoms are often minimal – if symptomatic, a posterior shoulder or scapular burning type of pain may be reported. Some injuries, particularly lesions, can paralyse the serratus anterior muscle to produce a winged scapula. [3] [12] This is most prominent when the arm is lifted forward or when the patient pushes the outstretched arm against a ...
