Dislocation of Carpometacarpal Joint of Left Thumb, Sequela

Dislocation of the carpometacarpal (CMC) joint of the left thumb is a severe injury that can have long-term consequences. When left untreated or not properly managed, this dislocation can lead to a range of sequelae, or secondary conditions. Understanding the potential complications is crucial for both patients and healthcare professionals.

1. Post-Traumatic Arthritis:

One of the most common sequelae of a dislocated CMC joint of the left thumb is post-traumatic arthritis. The trauma to the joint can lead to the breakdown of cartilage, causing pain, stiffness, and reduced range of motion. This condition may develop gradually over time and may require ongoing management.

2. Ligament Instability:

A dislocation can damage the ligaments that support the CMC joint, leading to instability. This instability can result in chronic pain and recurrent episodes of joint dislocation. Patients may experience difficulty grasping objects or performing fine motor activities, affecting their overall hand function.

3. Weakness and Muscle Imbalance:

The dislocation can also disrupt the normal muscle balance around the thumb, leading to weakness and muscle imbalances. This can further impair hand function and may require targeted rehabilitation to restore strength and coordination.

4. Chronic Swelling and Tenderness:

Chronic swelling and tenderness are common sequelae of a dislocated CMC joint. The joint may remain chronically swollen, making it difficult to wear certain types of gloves or engage in activities that put pressure on the thumb. The persistent tenderness can also cause discomfort during daily activities.

1. 5. Reduced Grip Strength:

The dislocation and subsequent sequelae can significantly impact grip strength. Reduced grip strength can affect various aspects of daily life, including holding objects, opening jars, or performing tasks that require hand strength.

Understanding the potential sequelae of a dislocated CMC joint of the left thumb is essential for patients and healthcare professionals. Timely diagnosis, appropriate treatment, and rehabilitation can help minimize the impact of these sequelae and improve long-term outcomes.
