Proximal symphalangism – http://id.who.int/icd/entity/49802338

Proximal symphalangism or Cushing's symphalangism is characterised by fusion of the proximal interphalangeal joints. Other joints may also be affected, leading to ankylosis of the elbows, ankles and wrists (fusion of the carpal and tarsal bones). Conductive deafness due to fusion of the ossicles is also a characteristic feature.
