  1. When performing a subtalar joint arthroereisis for pediatric flatfoot, where is the implant placed?

    Answer: Sinus tarsi

    The arthroereisis implant is inserted into the sinus tarsi to mechanically block excessive pronation and subtalar joint eversion.

  2. Which principle governs the appropriate level of Kirschner wire placement when treating an unstable fifth metatarsal base fracture (Jones fracture) with intramedullary screw fixation?

    Answer: The screw should be placed along the long axis of the metatarsal shaft

    Intramedullary screw fixation of Jones fractures requires placement along the medullary canal axis of the fifth metatarsal for optimal purchase.

  3. A patient presents with a recurrent ingrown toenail. Which procedure provides the most definitive long-term resolution?

    Answer: Partial nail avulsion with phenol matrixectomy

    Partial nail avulsion followed by phenol matrixectomy destroys the germinal matrix of the offending nail border, providing the highest success rate for permanent correction.

  4. During calcaneal osteotomy for cavovarus foot correction, which direction is the calcaneus translated to reduce lateral column overload?

    Answer: Laterally

    In cavovarus correction, the calcaneus is shifted laterally to reduce varus heel alignment and redistribute plantar pressure.

  5. What is the recommended tourniquet inflation pressure for an ankle tourniquet in an adult patient with a systolic blood pressure of 120 mmHg?

    Answer: 250 mmHg

    Ankle tourniquet pressure is typically set at 250 mmHg or approximately twice the systolic blood pressure to achieve hemostasis.

  6. Which classification system is most commonly used to stage osteochondral defects of the talus?

    Answer: Berndt and Harty classification

    The Berndt and Harty classification stages talar osteochondral lesions from I (compression) through IV (displaced fragment) based on radiographic appearance.

  7. In first metatarsophalangeal joint arthrodesis, what is the recommended position for fusion in the sagittal plane?

    Answer: 15–20 degrees of dorsiflexion

    The first MTP joint is fused at 15–20 degrees of dorsiflexion relative to the ground to permit normal toe-off during gait.
