The patient's skin is intact with no sign of ulcerations or callosities. His left foot is developing a varus deformity secondary to a spastic tibialis anterior. His ankle has a 5 degree plantar flexion deformity due to a gastrocnemius contracture which improves with knee flexion (positive Silverskiold test). The patient has an intrinsic minus foot with supple claw toes present. Which of the following is the most appropriate next step in management? Tested Concept QID: 1217 Type & Select Correct Answer 1 Gastrocnemius fascia lengthening (Strayer) procedure 15% (316/2050) 2 Split anterior tibial tendon transfer (SPLATT) 14% (294/2050) 3 Flexor hallucis longus tendon transfer to the dorsum of the foot and release of the flexor digitorum longus and brevis tendons at the base of each toe 9% (193/2050) 4 Fractional lengthening of the tibialis posterior 0% (7/2050) 5 Ankle foot orthosis (AFO) with physical therapy 60% (1229/2050) L 2 Question Complexity C Question Importance Select Answer to see Preferred Response SUBMIT RESPONSE 5 Review tested concept
