PEDIATRIC MCQS: Orthopedics

PEDIATRIC MCQS

Q1

A 12-hour-old infant undergoes a physical examination in the newborn nursery. It is noted that there is inward torsion of the forefoot bilaterally that is easily reduced with passive movement of the foot. You diagnose metatarsus adductus.

Given the diagnosis of metatarsus adductus, what other diagnosis should the patient be

evaluated for?

a. Clubfoot

b. Myelomeningocele

                                  c. Developmental dysplasia of the hip (DDH)

                                  d. Clavicular fracture

                                  e. Pes planus

Q2

A 6-year-old is brought to the office because her parents are concerned over her clumsiness. They state that she tends to trip over her feet when she walks. On your physical examination, you note an intoeing gait bilaterally. On closer inspection, it appears that

her patellae are inwardly deviating as she walks. Her neurologic examination, including muscle strength, is completely normal. 

The most common cause of this intoeing gait would be:

a. Internal tibial torsion

b. Femoral anteversion

c. Slipped capital femoral epiphysis

d. Metatarsus adduction

e. Bilateral Salter I fractures of the tibia

Q3

In the normal child, genu varum (bowlegs) is maximal at which age?

a. Adolescence

b. Age 10 to 12

c. Newborn period

d. Age 3 to 5

e. Age 6 to 9

Q4

A mother brings her 6-year-old daughter to your office for evaluation of her “knock-knees.” Your examination demonstrates symmetric valgus deformity of the knees bilaterally, normal range of motion of the hips, knees, and ankles, and no leg length discrepancy. The best

next step would be:

a. Radiographs of the legs to exclude fracture

b. Reassurance of the parent

c. Evaluations of serum calcium and phosphate

d. Prescription of orthotics

e. Referral to physical therapy for strength building exercises

Q5

Which of the following conditions is associated with developmental dysplasia of the hip?

a. Tibial torsion

b. Congenital scoliosis

c. Torticollis

d. Branchial cleft disorders

e. Femoral anteversion
