Test on Pediatric Wrist and Forearm Malformations

Question 1: The peroneal vessels are ligated at the level of the distal osteotomy.

A. Ano

B. Ne

Explanation: The study materials explicitly state, "The peroneal vessels are then ligated at the level of the distal osteotomy."

Question 2: According to the study materials, what is the appropriate extent of resection for pseudarthrosis?

A. The entire pseudarthrosis

B. Only the distal half of the pseudarthrosis

C. The pseudarthrosis back to healthy bone

D. A small segment of the pseudarthrosis

Explanation: Figure 42.42 clearly states 'Resection of entire pseudarthrosis back to healthy bone.' Therefore, both 'the entire pseudarthrosis' and 'the pseudarthrosis back to healthy bone' are correct descriptions of the extent of resection.

Question 3: Combining radial head reduction with corrective ulnar osteotomy has been proven effective for congenital dislocation of the radial head (CDRH).

A. Ano

B. Ne

Explanation: The procedure combining radial head reduction with corrective ulnar osteotomy has yet to be proved effective for congenital dislocation of the radial head (CDRH).

Question 4: What is the authors' preferred initial approach for managing most cases of Congenital Dislocation of the Radial Head (CDRH)?

A. Open reduction with soft tissue reconstruction of the annular ligament

B. Radial head excision

C. Observation

D. Combining radial head reduction with corrective ulnar osteotomy

Explanation: The study materials state under 'AUTHORS’ PREFERRED METHOD OF TREATMENT' that 'Because most young children are relatively asymptomatic, most cases of CDRH are managed by observation.'

Question 5: Following centralization, a long arm Orthoplast splint is typically worn only at night for the first 3 to 6 months.

A. Ano

B. Ne

Explanation: After centralization, a long arm Orthoplast splint is worn full-time for 3 to 6 months, and then indefinitely at night.
