PCM 3 UE Hand and wrist Questions with Correct Answers (Grade
A+)
Question 1: What are the 2 major joints in the wrist?
Answer: - Radiocarpal Joint - Distal radioulnar joint
Question 2: What movements are the radio- carpal joints responsible for?
Answer: - Flexion and extension
Question 3: What movement does the mid carpal joint do?
Answer: - Flexion + Ulnar deviation - Extension with radial deviation
Question 4: Hand and wrist red flags?
Answer: - Scars - Redness/Infection - Edema - Atrophy/Hypertrophy
Question 5: Capsular pattern of wrist?
Answer: Limitations in flexion and extension
Question 6: Common Wrist Ulnar N entrapment location?
Answer: Guyons canal
Question 7: Where is Guyons Canal Located
Answer: On the ulnar side of the wrist, lateral to the pisiform bone and palmar to the flexor retinaculum
Question 8: Soft Tissue structures around Guyons canal?
Answer: - FDP - Opponens digiti minimi - Abductor Digiti Minimi - Flexor Tendons
Question 9: TFCC?
Answer: triangular fibrocartilage complex, Provides smooth gliding surface for wrist on carpals to cushion
force and allow for connection of bony structures
Question 10: TFCC location?

, Answer: Between medial and proximal row and along the dis- tal ulna within the medial aspect of the wrist
Question 11: Zone 2 flexor tendon laceration?
Answer: - No mans land - Houses sheaths and pulleys - Has poor blood supply - FDP and FDS severed
