Dislocation or Subluxation

Description

Dislocation is injury to a joint that causes adjoining bones to no longer touch each other. Subluxation is a minor or incomplete dislocation in which the joint surfaces still touch but are not in normal relation to each other. The structures involved are the ligaments and bones in the joints, especially in the shoulders, kneecaps, and fingers. Occasionally there may be an associated fracture.

Common signs and symptoms

• Sudden joint pain

• Swelling

• Deformity after an injury

• Limited or absent movement around a joint

Causes

• A traumatic injury that stretches or tears ligaments that surround a joint and hold the bones together

• Shallow or abnormally formed joint surfaces (congenital)

• Rheumatoid arthritis or other diseases of the ligaments and tissues around a joint

Factors that increase risk

• Repeated injury to a joint

• Previous dislocation of a joint

• Contact sports or sports that require repetitive overhead arm motion (throwing, swimming, volleyball)

• Rheumatoid arthritis

• Congenital looseness of joints and ligaments
