Card 1
Question: What postoperative immobilization is used after using an FDS tendon slip to reconstruct the UCL in pediatric thumb reconstruction, and when is active
Answer: Skin closed with absorbable sutures; long-arm thumb spica splint for 3 weeks, then short-arm thumb spica splint and active motion is started.
Card 2
Question: How is tendon transfer training initiated after a tendon transfer in pediatric thumb reconstruction?
Answer: By incorporating the transfer into daily activities as soon as the transfer is firing.
Card 3
Question: Which extrinsic tendon can be transferred to replace extensor pollicis longus function in a type IIIA thumb?
Answer: The extensor indicis proprius from the adjacent index finger.
Card 4
Question: What additional problem may complicate reconstruction of the flexor pollicis longus in pediatric thumb reconstruction?
Answer: The flexor tendon sheath may be deficient, requiring pulley reconstruction combined with tendon centralization or tendon transfer (or both).
Card 5
Question: What is the general surgical goal of skin incision design for pollicization in thumb reconstruction?
Answer: To create a thumb with sufficient skin coverage and an adequate first web space that is devoid of scar.
Card 6
Question: Which modified skin incision is used to achieve more glabrous palmar skin after pollicization?
Answer: A modified design by Ezaki and Carter (modification of the Buck-Gramcko incision) is used to yield more glabrous palmar skin.
Card 7
Question: What is the purpose of gentle exsanguination and tourniquet inflation at the start of pollicization?
Answer: To allow identification of the vasculature.
Card 8
Question: During pollicization for type IIIB or IV thumbs, what is done with the hypoplastic thumb?
Answer: Excision of the hypoplastic thumb is incorporated into the incision; it usually has a single digital nerve and artery.
Card 9
Question: How is the radial digital artery of the index finger identified during pollicization?
Answer: The artery from the hypoplastic thumb is traced proximally to its bifurcation with the radial digital artery of the index finger, facilitating identif
Card 10
Question: Which nerves are identified and traced during pollicization to allow tension-free transfer of the index finger?
Answer: The proper digital nerves to the ulnar side of the index finger and the radial side of the long finger, traced proximally with microdissection of the
