ABFAS - Trauma Section questions with correct answers

Achilles tendon rupture is likely to occur in this position - Correct Answer-Sprinters Gastroc-soleal complex is enervated by: - Correct Answer-Tibial nerve (S1 - S2) Runs between the gastrocnemius and soleus. Assists in plantarfexion of the foot and flexion of the knee - Correct Answer-Plantaris Nerve enervation of the plantaris - Correct Answer-L4, L5, S1 The narrowest part of the achilles tendon - Correct Answer-4cm proximal to its insertion An Achilles tendon rupture is likely to occur at what anatomical location? - Correct Answer-2-6cm proximal to attachment (watershed area) of the left lower extremity (due to handedness: Right handed individuals more commonly push off with the left foot). Name the Test: squeezing of the calf muscle does not result in plantar flexion of the foot - Correct Answer-Thompson Test Name the Test: A 25 gauge needle is inserted at a right angle to the leg through the skin of the calf muscle just medial to midline. This should be performed 10 cm proximal to the calcaneal insertion of the Achilles tendon. Motion of the hub of the needle in a direction opposite that of the tendon during passive dorsiflexion and plantarflexion of the foot confirms an intact tendon distal to the level of needle insertion. - Correct Answer-O'Brien Test
