Dislocation of Metacarpophalangeal Joint of Left Thumb, Sequela: Causes, Symptoms, and Complications

Dislocation of the metacarpophalangeal (MCP) joint of the left thumb is a severe injury that can lead to long-term complications. This condition, also known as MCP joint dislocation, occurs when the bones that form the joint are forced out of their normal position. When left untreated or not properly managed, it can result in long-lasting sequelae.

Causes:

1. Direct trauma: A sudden impact or blow to the thumb, such as during a sports-related injury or accident, can cause the MCP joint to dislocate.
2. Hyperextension: Overextending the thumb beyond its normal range of motion, often due to a forceful bending or twisting motion, can result in joint dislocation.
3. Ligament damage: A severe sprain or tear to the ligaments supporting the MCP joint can weaken the joint and make it more susceptible to dislocation.

Symptoms:

• Visible deformity: Dislocation of the MCP joint can cause the thumb to appear misaligned or bent at an abnormal angle.
• Severe pain: Patients often experience intense pain at the site of the injury.
• Swelling and bruising: The thumb may become swollen and discolored due to the damage to the surrounding tissues.
• Restricted movement: Dislocations can limit the range of motion of the thumb, making it difficult to perform everyday tasks.

Complications:

If left untreated, dislocation of the MCP joint of the left thumb can lead to several complications:

1. Chronic pain: The persistent pain associated with untreated MCP joint dislocation can significantly impact an individual's quality of life.
2. Joint instability: Without proper treatment, the joint may remain unstable, making it prone to future dislocations.
3. Functional limitations: The restricted movement resulting from a dislocated MCP joint can hinder the thumb's ability to grasp, grip, and perform fine motor tasks.
4. Development of arthritis: Long-term joint instability can increase the risk of developing arthritis in the affected thumb joint.

Seeking prompt medical attention is crucial when dealing with a dislocation of the MCP joint of the left thumb. A healthcare professional can assess the injury, provide appropriate treatment, and help prevent potential sequelae.
