Your patient has a diagnosis of RA and is developing a capsular pattern in the foot and ankle.Which joint-mobilization technique could perpetuate or worsen the impairment/deformity typically associated with RA of the foot and ankle?

Accepted Answer

A)  Stabilize the mortise and glide the talus in an anterior direction
B)  Stabilize the calcaneus and glide the cuboid in a plantar direction
C)  Stabilize the talus and glide the navicular in a dorsal direction

Question 8

Each of the following is true about surgical repair/reconstruction of the lateral ligament complex of the ankle and postoperative management except:

Accepted Answer

A)  The most common procedure is a direct repair and imbrication of the torn ligaments through an open surgical approach.
B)  After reconstruction of the lateral ligaments that includes a tendon autograft and tendon transposition (often the peroneus brevis tendon)  to reinforce the lateral aspect of the ankle, there may be some permanent loss of full ankle inversion postoperatively.
C)  The ankle is immobilized in plantarflexion and slight eversion for 4 to 6 weeks postoperatively; therefore, the patient must remain nonweight bearing on the operated lower extremity during the period of immobilization to prevent rupture of the repair site.
D)  It is usually permissible to remove the ankle immobilizer by about 4 to 6 weeks postoperatively to begin active ROM exercises of the ankle.

Question 9

Which of the following most accurately describes the deformities that progressively develop in rheumatoid arthritis (RA) of the foot/ankle?

Accepted Answer

A)  Fixed supination of the foot, hallux valgus, hallux rigidus, dorsal subluxation of the proximal phalanges on the metatarsal heads
B)  Fixed pronation of the foot, hallux valgus, hallux rigidus, plantar subluxation of the proximal phalanges on the metatarsal heads
C)  Fixed pronation of the foot, hallux valgus, hallux rigidus, dorsal subluxation of the proximal phalanges on the metatarsal heads
D)  Fixed supination of the foot, hallux valgus, hallux rigidus, plantar subluxation of the proximal phalanges on the metatarsal heads

Question 10

During initial evaluation of a patient with a complaint of low back pain, you perform a standing posture alignment screening and discover that his left leg appears shorter than the right as you compare iliac crests, greater trochanter, head of the fibula, and medial malleolus.What related possible foot deformity should you look for while still in standing?

Accepted Answer

A)  Excessive right foot pronation compared with the left
B)  Excessive left foot pronation compared with the right
C)  Excessive left foot supination compared with the right
D)  Hallux valgus on the right

Question 11

Which one of the following ligaments of the ankle is most frequently stressed with an inversion sprain?

Accepted Answer

A)  Posterior talofibular
B)  Anterior talofibular
C)  Calcaneofibular

Question 12

Each of the following is a true statement about total ankle arthroplasty (TAA) and postoperative rehabilitation except:

Accepted Answer

A)  At the close of surgery, the foot and ankle typically are immobilized in a neutral position in a well-padded compression dressing and short-leg posterior splint.
B)  A patient with peripheral arterial disease of the lower extremities in addition to advanced arthritis of the ankle is not an appropriate candidate for TAA.
C)  After a TAA that involved biological fixation, weight bearing on the operated lower extremity during ambulation with a walker initially is permissible only while wearing an ankle immobilizer and may need to be partially restricted for several weeks to allow time for some degree of bio-ingrowth to occur.
D)  TAA is an appropriate procedure for a patient with advanced arthritis combined with marked instability of the ankle.

Question 13

Question 15

Your patient sustained a fracture of the right calcaneus as the result of a motor vehicle accident 3 months ago.After 10 weeks in a cast followed by a rocker bottom immobilization boot that prevented ankle and foot motion, the fracture shows radiological evidence of bony union.The patient has been ambulating (weight bearing as tolerated) while wearing the boot and is now supposed to discontinue wearing it slowly.Your examination reveals marked limitation of dorsi- and plantarflexion and a high, rigid arch.There is no visible swelling, and pain (2/10) occurs at the end of the day and during passive range of motion (PROM) with overpressure.Which of the following is the most appropriate intervention during the first week of therapy?
