A

Osteochondritis dissecans

(dx: xray showing avascular bone/ radiolucency lesion along lateral portion of medial femoral condyle with fragment of partially attached subchondral bone)

24
Q

What is the treatment for osteochondritis dissecans?

A 
conservative therapy (restriction of activity until pain free and healing on repeat Xray)
 -if loose bodies, closed physes, or no improvement after 4-6 months, then surgery
25
Q

What is the most likely diagnosis for a pt presenting with elbow pain, tenderness and pain around the medial epicondyle, and pain reproduced with flexion of the wrist/?

A

Medial Epicondylitis

Golfer’s Elbow

26
Q

What is the most common cause of in-toeing (feet internal rotated) and when should intervention be considered?

A

internal tibial torsion (lateral malleolus is slightly anterior to medial malleolus when legs dangling in seated position)
intervention if persists beyond 8 years old

27
Q

…. is when the forefoot is adducted; therefore, a line that bisects the base of the hindfoot forward to the toes passes lateral to between then 2nd and 3rd toe

A

Metatarsus Adductus

(if flexible/ can passively abduct past midline, will resolve by 1 year old)
(if not flexible, refer to Ortho for serial casting)

28
Q

What is the likely diagnosis for an adolescent male going through growth spurt presenting with knee pain localized to tibial tubercle, worsened by direct trauma, kneeling, running, jumping, squatting, climbing stairs, or walking uphill, and pain reproduced by extending knee against resistance, stressing quad, or squatting with knee in full flexion?

A

Osgood- Schlatter

tx: RICE -> physical therapy and/or orthotics –> steroid injections

29
Q

What is the most likely diagnosis for pt presenting with high-riding, hypoplastic
and rotated scapula, asymmetry of base of neck and shoulders, and possible torticollis/ scoliosis?

A 
Sprengel deformity
(associated with Klippel-Feil syndrome)
30
Q

What is the likely diagnosis for pt presenting with high-riding, hypoplastic, and rotated scapula and fused and hypoplastic cervical vertebrae resulting in short, broad, webbed neck, low hairline and limited ROM?

A

associated with anomalies of heart, lungs, kidneys

A

general activity encouraged without restrictions

39
Q

What is the treatment for scoliosis between 25 and 45 degrees?

A

consider bracing

40
Q

What is the treatment for scoliosis > 45 degrees?

A

Spinal fusion or placement of Harrington rod

41
Q

What is the most likely diagnosis for pt presenting with knee pain along joint line, popping or locking sensation, and pain and popping in medial joint line with slow extension of left knee from flexed position (positive McMurray test) after twisting injury?

A

Medial meniscal tear

42
Q

Why does the NCAA recommend that all collegiate athletes be tested for sickle cell trait?

A

possible sudden death from exertional rhabdomyolysis (exertional sickling)

excision if not improved after 6-12 months

44
Q

What is the most common mechanism of injury resulting in an ACL (anterior cruciate ligament) tear?

Q

What does a positive Lachman test suggest?

A

torn ACL (anterior cruciate ligament)

-anterior translation of tibia > 2mm different from unaffected leg when knee 30 degree flexed, femur stabilized at thigh and pull tibia forward)
