Surgical Interventions & Procedures Flashcards

Which osteotomy is most commonly used to correct a hallux valgus deformity at the first metatarsal shaft level?

Answer: Scarf osteotomy

The scarf osteotomy is a long Z-shaped cut through the first metatarsal shaft that allows multiplanar correction of hallux valgus deformity.

What is the primary indication for a Lapidus procedure in hallux valgus correction?

Answer: Elevated intermetatarsal angle with hypermobility of the first ray

The Lapidus arthrodesis addresses hypermobility at the first tarsometatarsal joint, which is often the underlying cause of an elevated intermetatarsal angle.

During an Achilles tendon repair, which suture technique is considered the gold standard for end-to-end tendon repair?

Answer: Kessler or modified Kessler technique

The Kessler and modified Kessler suture techniques provide superior tensile strength for end-to-end Achilles tendon repairs compared to other methods.

Which nerve is most at risk during a medial approach to the ankle for deltoid ligament repair?

Answer: Saphenous nerve and great saphenous vein

The saphenous nerve and great saphenous vein travel along the medial ankle and are at risk during medial approach incisions for deltoid ligament repair.

A Dwyer calcaneal osteotomy corrects which deformity?

Answer: Calcaneal varus (cavovarus foot)

The Dwyer lateral closing wedge osteotomy removes a lateral wedge from the calcaneus to correct calcaneal varus in cavovarus foot deformities.

What is the purpose of a gastrocnemius recession (Strayer procedure) in podiatric surgery?

Answer: To selectively lengthen the gastrocnemius at the musculotendinous junction

The Strayer gastrocnemius recession selectively lengthens the gastrocnemius at its musculotendinous junction, preserving soleus function and reducing equinus contracture.

Which approach provides the best exposure for subtalar joint arthrodesis?

Answer: Sinus tarsi (lateral oblique) approach

The sinus tarsi lateral oblique approach provides excellent visualization of the posterior and middle facets of the subtalar joint for arthrodesis preparation.
