Tarsal-carpal coalition syndrome is a rare congenital disorder characterized by the fusion of two or more bones in the foot and/or hand. It is caused by the abnormal development of the tarsal and carpal bones, which normally form separate joints. Symptoms of the condition can include pain, stiffness, and limited range of motion in the affected joints. Treatment typically involves physical therapy, splinting, and/or surgery.

The symptoms of Tarsal-carpal coalition syndrome vary depending on the severity of the condition. Common symptoms include:

-Pain in the feet, ankles, and lower legs

-Swelling in the feet, ankles, and lower legs

-Stiffness in the feet, ankles, and lower legs

-Difficulty walking or running

-Flat feet

-Abnormal gait

-Weakness in the feet, ankles, and lower legs

-Loss of range of motion in the feet, ankles, and lower legs

-Numbness or Tingling in the feet, ankles, and lower legs

-Deformity of the feet, ankles, and lower legs

Tarsal-carpal coalition syndrome is a rare congenital disorder caused by the fusion of two or more bones in the foot and/or wrist. The exact cause of this condition is unknown, but it is believed to be due to a genetic mutation or a combination of genetic and environmental factors. Possible causes include:

1. Genetic mutations: Certain genetic mutations can cause the bones in the foot and/or wrist to fuse together.

2. Environmental factors: Exposure to certain environmental toxins or radiation may increase the risk of developing this condition.

3. Trauma: Trauma to the foot or wrist may cause the bones to fuse together.

4. Infection: Certain infections, such as tuberculosis, may cause the bones to fuse together.

1. Non-surgical treatments:

- Physical therapy: This can help to strengthen the muscles around the affected joint and improve range of motion.

- Orthotics: Custom-made orthotics can be used to provide support and stability to the affected joint.

- Medications: Non-steroidal anti-inflammatory drugs (NSAIDs) can be used to reduce pain and inflammation.

2. Surgical treatments:

- Arthrodesis: This is a surgical procedure that involves fusing the affected joint together to reduce pain and improve stability.

- Osteotomy: This is a surgical procedure that involves cutting and reshaping the bones of the affected joint to improve range of motion.

- Joint replacement: This is a surgical procedure that involves replacing the affected joint with an artificial joint.
