Boutonniere Deformity occurs within the fingers or toes, when the joint closest to the knuckle (PIP) is bent towards the palm and the furthest joint (DIP) of the finger is bent backwards.
- Inflammatory condition - rheumatoid arthritis
- Genetic conditions
The symptoms for Boutonniere Deformity are mostly visual. You can see the fingers or toes will be deformed from a slipped tendon. This can happen when the finger is hit or bent forcefully. It can also occur over time due to rheumatoid arthritis.
Depending on the severity of the deformity will determine the treatment plan. Advanced Soft Tissue Release, ASTR, may be able to help relieve the nerve pain. A splint is sometimes used to correct the deformity by holding the finger in an extended position, but there can be other deformities while healing in a splint. When the splint is ineffective, surgery may be necessary.
