How is the term “dislocation” defined in orthopedic terminology?

In orthopedic terminology, a dislocation is defined as a complete displacement of a bone from its joint. This means that the surfaces of the bones that normally articulate with each other have lost contact entirely. This condition often involves significant injury to the ligaments, tendons, and surrounding soft tissue structures that stabilize the joint.

Properly identifying a dislocation is crucial because it requires prompt reduction (returning the bone to its proper position) and may often necessitate further treatment to address any associated injuries and prevent long-term complications. Understanding this definition allows healthcare providers to effectively assess and manage injuries related to joint stability and integrity. The other options describe different types of joint injuries but do not accurately capture the complete displacement characteristic of a dislocation.
