Curtis plasty is an effective option for correcting supple boutonnière deformity.

Boutonnière deformity is characterized by flexion of the proximal interphalangeal (PIP) joint and hyperextension of the distal interphalangeal (DIP) joint, often caused by trauma or rheumatoid arthritis. When the deformity remains supple without fixed contractures, tendon reconstruction techniques such as the Curtis plasty can restore function and correct alignment.
