Q

How is the straight leg raise performed?

A

Raise leg, if reproduce leg pain radiation, lower leg just to point of no pain then dorsiflex foot. This stretches sciatic nerve so if dermatomal pain reproduced again, more likely is sciatic nerve. Most commonly positive for sciatica if pain found between 40-60 degrees of extension

A

The Faber test.

“F”lexion “AB”duction “External Rotation”

Most specific for hip joint.Trying to reproduce their pain. May elicit SI tenderness

30
Q

What is housemaids knee, and how does one get it?

A

•Prepatellar Bursitis: Anterior
–Dome swelling over patella associated with tenderness
–From excessive kneeling

31
Q

What is a common cause of anserine bursitis?

A

–Excessive running common cause
–Also from valgus knee deformity (Q angle) and arthritis

32
Q

Where is a Baker’s cyst found? How do you check for one?

A

–Cyst in the popliteal fossa, most often medial
–Leg extended check posterior/medial aspect of knee for swelling or fullness, sometimes tenderness as well

33
Q

How do you check for bulge sign?

A

Bulge Sign: minor effusions in Suprapatellar pouch

34
Q

How is ballotting done?

A

Ballotting: Compress suprapatellar pouch, use other hand to sharply press patella to feel for fluid returning to suprapateallar pouch. Also for large effusions

35
Q

What does patellofemoral grind test identify?

How is it done?

A

—Chondromalacia or patellofemoral syndrome

—Patient supine with knee extended
—Compress patella against femur
—Instruct patient to tighten quads.
—Assess for roughness of motion, crepitus, pain

36
Q

How do you perform the apprehension test, and what is it good for?

A

—Tests for dislocation or subluxation of patella
—Attempt to manually dislocate patella laterally
—Observe patient’s facial expressions

37
Q

What is the meaning of a positive anterior drawer sign?

A

ACL tear

38
Q

What is the Lachman test good for?

How is it done?

A

Only for ACL

  • Knee flexed 15˚ and externally rotated if possible
  • Grasp femur with one hand and tibia with other
  • Move femur and tibia in opposite directions
  • Asymmetric, forward movement of tibia against femur suggests positive test = ACL tear
39
Q

What is the result of a + Posterior drawer sign?

A

PCL tear

40
Q

What does the McMurray test evaluate?

How is it done?

A

Meniscus

  1. —Patient supine grasp heel and fully flex the knee
  2. —Hold knee joint with other hand palpating along joint line
  3. —Rotate the lower leg internally to engage the lateral meniscus and extend the leg. Note pain; “pop” or “click” during the motion. Repeat using external rotation for the medial meniscus. Not a very specific test.
41
Q

What does Apley’s compression test evaluate?

How is it done?

A

Meniscus

  1. —Patient prone with knee flexed to 90˚
  2. —Stabilize thigh with one hand while leaning onto heel compressing medial and lateral menisci. Rotate heel during compression noting any pain
42
Q

What are three key features of a meniscal tear?

A
  1. Locking or giving out: sensation of or actual occurrence
  2. Not feeling they can trust the knee when walking or stepping off a curb
  3. A catching sensation or true catching of the knee: sudden pain stops ROM, ie, suddenly cannot extend the leg fully.
43
Q

In the McMurray test, with the knee at 90 degrees how would you test the medial meniscus?

A

Externally rotate tibia = heel points in/toward midline

Extend knee feeling for click, looking for pain

44
Q

In the McMurray test, with the knee at 90 degrees how would you test the lateral meniscus?

A

Internally rotate tibia = heel points out/away from midline

Extend knee feeling for click, looking for pain

45
Q

How specific is the McMurray test?

A

Not very sensitive test for meniscus, ie, can still have injury without positive findings.

Specificity=85-95%

Sensitivity=50-65%

46
Q

What is a more sensitive and specific test for meniscal injury or tear than McMurray?

How is it done?

A

Thessaly test

Standing, rotatory motion on one leg bent to 5-10 deg, and again at 20 degrees.

47
Q

What stress test is used to evaluate the MCL?

How is it done?

A

Valgus stress test.

—Patient supine and flex knee slightly
—One hand against lateral knee the other around medial ankle
—Push medially against knee while laterally against ankle

48
Q

What is the stress test for the LCL, and how is it done?

A

•Varus Stress Test: (Adduction Stress Test)

—Push laterally against knee while medially against ankle

49
Q

What does Homan’s sign look for?

50
Q

What does the Thompson test evaluate?

How is it done?

A

Tests achilles

—Patient prone, leg bent 90 deg, squeeze calf and observe for normal passive plantar flexion. Best to determine achilles rupture if done in 48 hrs.

51
Q

What ankle ligaments are most commonly injured in sprains?

A

Anterior Talofibular (ATF = Always tears first)

Calcaneofibular

52
Q

How do you test for Morton’s Neuroma?

A

Compress the forefoot

53
Q

How is the Talar Tilt Test performed?

A

Pt is sitting with legs dangling off table

Doc inverts the calcaneus

If the talus gaps or rocks in the ankle mortise, the ATF & calcaneofibular ligs are torn and the test is positive

54
Q

A high ankle sprain impacts what joint?

A

—Syndesmosis between Fibula and Tibia

55
Q

According to the Ottawa rules, you would perform and X-ray if…

A

Pain around the malleolus and tenderness in posterior malleolar area or tip of fibula

OR

Pain around the malleolus and unable to weight bear immediately and more than 4 steps in ED

OR

Pain in mid-foot and either

   1. Tenderness at base of 5th metatarsal or              navicular, OR
   2. Unability to weight bear immediately OR more              than 4 steps in ED
56
Q

What is Kleiger’s test for?

A

High Ankle sprain, Deltoid ligament

57
Q

Hammertoes:

A

•hyperextension of MTP joint and flexion of IP joint (second toe most common)

58
Q

What is this?

A

•Onychomycosis: Fungus infected nails
