Broken Shoulder Blade Overview

The scapula or shoulder blade is a bony structure found on the upper back that connects the upper arm to the chest wall (thorax). It also forms the socket part of the shoulder joint connecting the upper arm (humerus) to the socket (glenoid). The acromion and coracoid processes are bony bumps found on the upper part of the scapula, and they function to connect the scapula to the collarbone. The scapula is surrounded by thick layers of muscle that are responsible for the smooth movement of the shoulder joint.

  • The shoulder blade (scapula) is rarely broken (broken bones are also called fractures). Of all bone breaks, shoulder blade breaks occur less than 1% of the time.

  • Scapular fractures occur more often in young men aged 25-45 years because of the activities and trauma they encounter. These occur with athletic activities, motor vehicle accidents, and other forms of blunt trauma.

  • Broken shoulder blades are often caused by heavy forces that might also include severe injuries to the chest, lungs, and internal organs.

  • Fractures (breaks) have been reported at many areas along the scapula.

Sprains and Strains Overview

The body is meant to move. Muscles allow that movement to happen by contracting and making joints flex, extend and rotate. Muscles attach on each side of the joint to bone by thick bands of fibrous tissue called tendons. When a muscle contracts, it shortens and pulls on the tendon, which allows the joint to go through a range of motion.

A strain occurs when the muscle tendon unit is stretched or torn. The most common reason is the overuse and stretching of the muscle. The damage may occur in three areas:

  • The muscle itself may tear.

  • The area where the muscle and tendon blend can tear.

  • The tendon may tear partially or completely (rupture).

Joints are stabilized by thick bands of tissue called ligaments which surround them. These ligaments allow the joint to move only in specific directions. Some joints move in multiple planes; therefore, they need mor...
