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 […]

Myhre syndrome is a rare disorder caused by pathogenic gain-of-function variants in the SMAD4 gene. Most of the patients have had de novo variants. There are several instances of autosomal dominant inheritance, and penetrance appears to be complete. We describe seven Brazilian patients, three of […]
