DPM Surgical Interventions & Procedures 3

Question 1

Which structure is at greatest risk of injury during a fibular osteotomy for ankle fracture fixation?

Accepted Answer

Sural nerve and peroneal tendons

Answer

The sural nerve and peroneal tendons are in close proximity to the fibula along its posterior and lateral borders, placing them at risk during fibular osteotomies.

Question 2

A Cotton osteotomy is used primarily to correct which deformity in flatfoot reconstruction?

Accepted Answer

Forefoot supination (dorsal opening wedge of medial cuneiform)

Answer

The Cotton osteotomy is a dorsal opening wedge osteotomy of the medial cuneiform that corrects forefoot supination in adult acquired flatfoot deformity.

Question 3

What is the most common complication of digital arthroplasty (Keller procedure) for hallux rigidus?

Accepted Answer

Transfer metatarsalgia and floppy hallux

Answer

Resection of the proximal phalanx base in the Keller procedure disrupts the windlass mechanism and intrinsic muscle attachments, commonly causing transfer metatarsalgia and a floppy, unstable hallux.

Question 4

During a tarsal tunnel release, which structure forms the roof of the tarsal tunnel?

Accepted Answer

Flexor retinaculum (laciniate ligament)

Answer

The flexor retinaculum, also called the laciniate ligament, forms the fibrous roof of the tarsal tunnel that is released to decompress the posterior tibial nerve.

Question 5

Which osteotomy is indicated to correct isolated hallux valgus interphalangeus (HVI) deformity?

Accepted Answer

Akin osteotomy (medial closing wedge proximal phalangeal osteotomy)

Answer

The Akin osteotomy removes a medial closing wedge from the proximal phalanx to correct valgus deformity that occurs at the interphalangeal joint of the hallux.
