Which ligament is described as the ligament on the back of the hand between the ulna and the wrist bones?

• A. Dorsal ulnocarpal ligament
• B. Distal interphalangeal joints of foot
• C. Inferior pubic ligament
• D. Plantar calcaneonavicular ligament

Answer: (A)

The main idea here is recognizing a ligament that directly connects the ulna to the carpal bones on the dorsal (back) side of the wrist. The dorsal ulnocarpal ligament runs from the ulna to the carpal bones on the back of the wrist, stabilizing the ulnocarpal part of the joint and helping keep the ulna and carpal bones aligned during movement. This makes it the best match for a ligament described as being on the back of the hand between the ulna and the wrist bones, and it’s also part of the broader ulnocarpal complex that supports the wrist. The other options refer to structures not located at the wrist: distal interphalangeal joints of the foot are toe joints; the inferior pubic ligament is in the pelvis; and the plantar calcaneonavicular ligament (the spring ligament) is in the foot supporting the arch.
