The shoulder joint is a ball and socket joint. A ball at the top of the upper arm bone (humerus) fits neatly into a socket, called the glenoid, which is part of the shoulder blade (scapula). The glenoid is surrounded by a ring of fibrous cartilage called the labrum for stabilization of the shoulder joint.
Fractures of the glenoid are rare but can occur due to major trauma or during high-energy sports activities.
The symptoms of a glenoid fracture may include shoulder pain, swelling, a deformity at the site of the fracture and inability to move the arm.
Your doctor will perform a thorough physical examination and order X-rays or a CT scan to determine the extent of the fracture and displacement of the joint.
Non-displaced fractures require immobilization in a sling for about six weeks. If the fracture has led to the displacement of the bones, then surgery may be required to correct and fix them with pins, plates or screws. Physical therapy may be recommended to aid recovery, and improve range-of-motion and strength of the arm.
