ABFAS RRA Practice Test Questions and Answers All Correct When performing a subtalar arthroeresis for a flexible pediatric flatfoot deformity, the release of which of the following anatomic structures that is encountered should be avoided so as not to destabilize the subtalar joint? - Answer-interosseous talocalcaneal ligament. Shown below is the closed injury of a patient whose neurovascular status is intact. What is the best initial treatment option? (Dislocated ankle with possible necrosis of anterior ankle) - Answer-Closed reduction What is the most common complication resulting from a Salter-Harris type III fracture of the distal tibia in a 9-year-old? - Answer-Angular deformity A 45-year-old male sustains a crushing-type injury to the left foot. Radio graphs are negative for fracture and dislocation. Which of the following tests is the most helpful in determining skin flap viability? - Answer-Fluorescein dye study Which of the following surgical principles is not correct when performing a posterior tibial tendon transfer for a dropfoot deformity? A. tendon should be attached under physiologic tension with ankle at 90 degrees. B. typically attached into lateral cuneiform in line with the tendon vector pull. C. passing tendon under the retinaculum decreases power but prevents bowstringing. D. Interosseous membrane window should be small to prevent syndesmotic instability. - Answer-Interosseous membrane window should be small to prevent syndesmotic instability. Under what condition is a bone stimulator most efficacious? - Answer-Hypertrophic nonunion Under what condition is a bone stimulator most efficacious? - Answer-Rocker sole shoe Following a tendon reconstruction of the ankle for lateral ligamentous instability a 30- year-old female developed a deformity of the big toe. On exam she has full range of motion of the metatarsophalangeal joint and good ankle stability. What is the most likely diagnosis? - Answer-Use of Peroneus longus for reconstruction Which of the following procedure(s) would be the most appropriate management strategy for treatment of a rigid flatfoot in an infant diagnosed with a pediatric congenital vertical talus deformity? - Answer-manipulation and weekly serial casting for 5 weeks followed by Achilles tendon lengthening and talonavicular joint pinning. A patient sustains a comminuted calcaneal fracture. Two months after injury the patient complains of clawing of the lesser toes and shoe gear irritation. What is most likely cause of this deformity? - Answer-Unrecognized compartment syndrome A 51-year-old sustains a tongue type calcaneal fracture. What negative sequelaewould occur with displacement of this fracture in the characteristic fashion? - Answer-Posterior skin necrosis Which of the following muscles are released with the plantar fascia and long plantar ligament when performing a Steindler stripping for a patient with significant pes cavus plantar soft tissue contracture? - Answer-flexor digitorum brevis, abductor digiti quinti, abductor hallucis.

D. securing wires directly to ring. - Answer-Acute crossing angle of wires Which of the following techniques would negatively impact function following ankle syndesmosis repair? A. failure to dorsiflex the ankle during fixation placement. B. tricortical rather than quadricortical screw fixation. C. use of a suture endobutton rather than screw fixation. D. stabilization of fibula to tibial incisura parallel to frontal plane. - Answer-stabilization of fibula to tibial incisura parallel to frontal plane
