DISI deformity

What is DISI deformity?

It involves a change in the alignment of two carpal bones located in the wrist joint. This alteration causes discomfort near the wrist, especially during extension. In the transition from the forearm to the hand, the joints no longer align properly, which leads to pain.

How does DISI develop?

DISI deformity can develop due to prolonged stress on a specific joint, such as when using crutches. People who naturally have more joint laxity are also more likely to develop it.

Other causes that may result in misalignment of these joints include:

• Acute trauma (fall) on an outstretched hand
• Congenital joint hypermobility
• Overuse due to occupational activities
• A scaphoid fracture
• Joint inflammation (Rheumatoid arthritis)

What are the symptoms?

DISI deformity has several symptoms, with the most common listed below:

• Pain when extending the wrist
• Loss of strength
• Pain at the joint
• Cracking/clicking during wrist movements

What is the treatment for DISI deformity?

Treatment varies greatly depending on the individual situation. In many cases, physical therapy can be effective. For those who need additional support, a splint treatment is the best solution. This brace or splint helps reduce the load on the affected joint, allowing it to recover more effectively. If neither approach proves successful, surgery may offer a solution. However, this is generally considered a last resort.

If DISI deformity is left untreated, the joints involved will eventually lead to wear and tear.
