Carpal fusion is seen in?: (A) Apert's syndrome, (B) Rheumatoid arthritis, (C) Post-traumatic cases, (D) All of the above
Answer is D. Ans DThe most commonly involved bones are the lunate and triquetrum. Multiple carpal coalitions are often associated with other anomalies including Apert syndrome, Ellis-van Creveld syndrome, Holt-Oram syndrome, Turner's syndrome.
