Musculoskeletal Flashcards

1
Q

Anterior glenohumeral shoulder D/L

A

Abducted and externally rotated. Shoulder will look “squared off”. Hill-Sachs lesion (groove on humeral head). Bankart lesion (glenoid inferior rim fracture). Reduce it. Rule out axillary nerve injury (prick them on the deltoid)

93
Q

Difference between hip fracture and hip dislocation?

Who gets it?

A

Children 4-10 mostly boys. Less in african americans.

96
Q

What is the hallmark feature of L-C-P disease?

A

Painless limping and loss of abduction and internal rotate. Pain that may radiate into the thigh, knee, or groin.

97
Q

How is L-C-P disease diagnosed?

A

XR shows increased density of femoral head and “crescent” sign.

98
Q

Best treatment for L-C-P disease?

A

Bed rest. NSAIDS. May need abduction bracing if abduction is lost.

99
Q

A young 7-16yo obese male has a painful limp with pain in the hip, thigh, and medial knee. The leg appears externally rotated. What is this? What endocrine issue might you suspect? Treatment?

A

SCFE. Hypothyroidism. Needs surgery. Immediately get off the leg (crutches). Increased risk of AVN

100

Axial loading. Will see “bump” or “wrinkle” in the bone line.

101
Q

Varus stress with rotation

A

LCL injury

102
Q

Valgus stress with rotation

A

MCL injury

103
Q

Treatment for LCL or MCL injuries?

A

Sprains (I) incomplete tears (II) - conservative (pain, PT, ROM exercises). Tears (III) - surgical repair.

104
Q

I was playing soccer and I suddenly felt a pop and immediate swelling. Then my knee started to buckle and I couldn’t straighten it. What test?

A

ACL. Lachman’s (pull tibia anteriorly and it should give more if positive). Anterior drawer test.

105
Q

What is the most commonly injured knee ligament? What causes it?

A

ACL. Non contact pivoting injury (deceleration, hyperextension, internal rotation)

106
Q

What is the most common cause of PCL injury?

A

Dashboard. (posterior force to anterior tibia with knee flexed.

107
Q

How do you test for PCL injury? How is it treated?

A

Posterior drawer and PIVOT SHIFT TESTING. Almost always surgical

108
Q

A pt says their knee locks, pops, and gives way and feels swollen whenever they are active. Test how?

A

Meniscal tear. McMurrays sign and Apley test.
Mcmurrays sign = pop or click while tibia is externally and internally rotated with flexion and extension of knee. Apley is applying downward pressure while pt lies prone and rotating externally and internally. Positive is popping, clicking, or pain.

109
Q

What gets torn most…medial meniscus or lateral?

A

Medial

110
Q

Knee fracture? What view?

A

Sunrise view of knee. Non displaced = Knee immobilizer with 6 week leg cast. Surgery if displaced.

111
Q

If the patella tendon ruptures…what would happen?

A

Patella atla (patella ABOVE so defect BELOW the knee)

112
Q

If the quad tendon ruptures…what would happen?

A

Patella baha (patella BELOW so defect above the knee

113
Q

Patellar dislocation. How. What. Treatment?

A

Valgus stress. Apprehension sign (move knee laterally). Reduce that thing (closed) by pushing anteromedially while extending leg.

114
Q

What if someone says they dislocated their knee?

A

BELIEVE THEM. This can be a popliteal artery injury and a perineal and tibial nerve injury. Immediate consult. Should get arteriography.

115
Q

How would you test for peroneal nerve injury?

A

1st web space:) - webby nuts

123
Q

Most common ankle sprain? Second most common?

A

ATL (anterior talofibular ligament) then calcaneofibular.

146
Q

How to remember L4-S1 sensation issues. 4 looks a little like an A = anterior thigh. Everything moves medially on the leg EXCEPT for things that are posterior. S1 is the back and bottom (being the last joint with herniated discs). So…L4 (4 looks like an A) starts with anterior thigh and moves medially to the medial ankle with sensory loss. L5 (L for lateral) starts lateral thigh and moves medially to the dorsum of the foot. S1 starts posterior leg and calf and MOVES straight down to the bottom (S1 is the bottom) of the boot (plantar surface). For weakness…L4 (L Four = Can’t DOR-SIFLEX). S1 (can’t STEP in shit or plantar flex). L5 (you have 5 toes and the the biggest is the Great toe). With reflexes. L4 (knee is higher than ankle) S1 ankle is lower than knee). L5 everything is alive:)

A

Remember remember remember!!!
