Glenoid Fractures

Anatomy of the Shoulder

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 stabilisation of the shoulder joint.

What are Glenoid Fractures?

Fractures of the glenoid are rare but can occur due to major trauma or during high-energy sports activities.

What are the Symptoms of a Glenoid Fracture?

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.

Diagnosis of Glenoid Fractures

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.

Treatments for Glenoid Fractures

Non-displaced fractures require immobilisation 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. Physiotherapy may be recommended to aid recovery and improve range-of-motion and strength of the arm.
