Scapula (Shoulder Blade) Fractures

Understanding Scapula (Shoulder Blade) Fractures

The scapula, or shoulder blade, is a triangular bone that connects the arm bone to the collarbone and forms the socket of the shoulder (glenoid). It is protected by thick muscles and the chest wall, so it usually breaks only with high-energy injuries such as car or motorcycle accidents or falls from a height.

Because these injuries involve so much force, scapula fractures often occur alongside rib fractures, lung injuries and other fractures, and are first treated by a trauma team. Fractures may involve the body of the scapula, the neck, the acromion or coracoid, or the glenoid socket itself.

Scapula fractures account for less than 1% of broken bones, and the vast majority heal well with a sling and early motion, typically within three to four months. Surgery is recommended for fractures that extend into the shoulder joint with a step-off, fractures that are significantly displaced or angled, and some combined collarbone and scapula injuries.

Causes & Risk Factors

• Motor vehicle and motorcycle accidents
• Falls from a height
• Direct high-energy blows to the shoulder

Symptoms

Common signs and symptoms of Scapula Fracture include:

• Severe pain with arm movement
• Swelling and bruising over the back of the shoulder
• Holding the arm close to the body
• Pain with deep breaths if ribs are also injured

Treatment Options

Treatment for Scapula Fracture depends on the severity of your condition and may include:

• A sling and pain management
• Early range-of-motion exercises and physical therapy
• Open reduction and internal fixation for displaced or joint fractures
