An irregularity in the close positioning of the two parts of a joint that prevents the joint from functioning normally. The most common large joint dislocation occurs in the shoulder, but joint dislocations may also occur in the shoulder, hip or spinal vertebrae. Symptoms of a joint dislocation include a misshapen appearance, pain, swelling, discoloration, and an inability to move the joint. A joint that is dislocated because of trauma is a serious injury and should be treated immediately. After giving the person a muscle relaxant, the doctor will gently rotate the dislocated joint back into place. In some cases, traction or surgery may be needed.
Complete displacement of the two bones within a joint occurs when they are no longer in contact, usually due to injury. This condition is commonly referred to as a dislocation. If the bones are only partially in contact after displacement, it is known as subluxation. Dislocations are typically accompanied by tearing of the joint ligaments and damage to the membrane that encases the joint.
Dislocation of a joint significantly limits or completely prevents its movement, resulting in considerable pain. The affected joint appears misshapen and becomes swollen. Injuries that are severe enough to cause dislocation often involve fractures as well. Unfortunately, in certain cases, dislocation can lead to complications like paralysis.
To confirm a dislocation and check for fractures, X-rays of the affected joint may be taken. Once diagnosed, the bones are carefully manipulated back into their correct positions, or in some cases, a surgical procedure is performed to reset them. After realignment, the bones are immobilized using a splint or cast, facilitating the healing process. This approach ensures the proper recovery and restoration of the joint’s functionality.
