MSK - Lower Extremity Flashcards
What is the most common source of hip pain? What three muscles (or groups) are usually involved?
Muscle strains
Hip adductors, rectus femoris, and iliopsoas
What typically limits apophyseal injuries? When is surgery required?
Periosteum
If displacement >1cm
What is myositis ossificans? What does it result from? What is the initial treatment? If causing prolonged pain?
Bone deposit in tissue
Results form multiple contusions to same area
Initial - ice and do not re-injure
Surgery to remove if persists
What is your initial inclining if someone presents with a flexed hip, IR, and adducted?
Posterior dislocation
What is your initial inclining if someone presents with a flexed hip, ER, and abducted?
Anterior dislocation
What is the initial treatment for hip dislocations? Why?
Imminent reduction
To reduce chance of AVN
If a pt presents with groin pain, audible/palpable clicking in the hip, and decreased ROM, what is your diagnosis? What imaging would you order?
Labial tear
MRI
What presentation of hip dislocation is most common?
Posterior
What is initial treatment for a hip labial tear? Secondary treatment?
Initial: partial wtb and PT
Secondary: surgery
What population is most susceptible to stress fractures of the femoral neck? What are the three types? Stable/unstable?
High endurance athletes/marathoners/mountain climbers
Compression - fx in inferior neck, stable due to compression with wtb
Tension - fx in superior neck, unstable due to separation while wtb
Displaced - unstable
What is osteitis pubis? Where will a pt often complain of pain radiating? What is the treatment?
Inflammation/compressior of pubic bones
Pain in pubic region, radiating around hip
Treatment: NSAIDs, rest, ROM
What is external snapping hip syndrome? What can often be inflammed as a result? What test is used clinically to diagnose snapping hip?
Tightness of IT snapping over greater trochanter
Greater trochanteric bursa
Ober’s test (pt lies on unaffected side, doctor abducts bad leg and lets go. Leg will remain abducted if there is a problem)
What causes internal snapping hip syndrome?
Tight iliopsoas (probably with bursitis)
What population is most susceptible to SCFE? What is seen in physical exam? What is the treatment?
11-14 year old AA and obese children
Flexed hip tends to externally rotate
Closed reduction with percutaneous screws
What is it called when a bump develops along the superior lateral neck of the femur, restricting motion? What is the initial treatment? Secondary
CAM impingement
Maintain flexibility, injections
Surgery to resect if absolutely necessary
What mimics bursisits or external snapping hip but causes pain with resisted abduction? What is conservative treatment?
Gluteus medius tear
RICE, heat, stretching
What is the flower test? What does it help diagnose?
Flex hip and externally rotate, positive if pain
Osteoarthritis of hip
What diagnostic tool is most helpful in determining hip AVN?
MRI
What is the treatment for an elderly individual with a displaced intracapsular femoral head fracture?
Hemiarthroplasty
What is treatment for intertrochanteric fractures?
ORIF
What is the structure most commonly traumatically torn?
Medial meniscus
Which meniscus is more circular? Which is half-moon shaped?
Lateral - more circular
Medial - half moon shaped
What is the McMurrary’s test? Describe position and what it checks for?
Flexed knee with rotation applied
IR - lateral meniscus
ER - medial meniscus
