Broken Shoulder Blade

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.

CT Scan Introduction

History

CT was discovered independently by a British engineer named Sir Godfrey Hounsfield and Dr. Alan Cormack. It has become a mainstay for diagnosing medical diseases. For their work, Hounsfield and Cormack were jointly awarded the Nobel Prize in 1979.

CT scanners first began to be installed in 1974. Currently, 6,000 scanners are in use in the United States. Because of advances in computer technology, CT scanners have vastly improved patient comfort because they are now much faster. These improvements have also led to higher-resolution images, which improve the diagnostic capabilities of the test. For example, the CT scan can show doctors small nodules or tumors, which they cannot see on an x-ray.

Introduction
