Pathologies and their relevant tests Flashcards
Labral tear
Physical exam: FADIR, FABER Flexion internal rotation - no pain pain. Good for ruling out (sensitivity). Pain on Thomas test
Patient Interview: Painful clicking in hip
Intra articular pathology (non specific)
FABER and Scour test (FADIR)-pain, screening tool. Thomas test - pain and reduced range, high sensitivity and specificity (positive likely to indicate injury).
Femoral fracture
Patellar pubic percussion - reduced percussion on side of pain.
Gluteal tendinopathy
Trendelenburg - drop in NWB pelvis.
Resisted hip abduction, resisted hip internal rotation - weakness and pain.
Three most useful tools with good specificity (hip abd has high sensitivity)
Resisted external deretoation test and single leg stance hold for 30 - Pain. Both have low clinical utility but can be useful screening tool.
Hip OA
Squatting aggravates symptoms (low LR-), lateral pain on active hip flexion (low LR- and high LR+) Scour test positive, pain with active hip ext, passive internal rotation <25 (low LR+)
ACL injury
Physical exam: Lachmans test - wanted soft end feel on tibial translation (specific and sensitive). Anterior draw test - >5mm tibial translation (specific). Pivot shift - anterior subluxation of tibia (specific, need intack MCL and ITB)
Patient Interview: Immediate (0-2 hr) swelling, audible pop or tear
MUST DO SAG SIGN to interpret this test (start further back may be perceived more movement)
PCL injury
Interview: Pain in posterior knee, pain with kneeling. Minimal swelling as it is extra synovial.
PE: Posterior sag sign (high specificity and can be highly sensitive). Posterior draw - >5 mm tibial translation (highly specific and can be highly sensitive) Reverse Lachman’s test - soft end feel on tibial translation (specific and moderately sensitive).
Meniscal tear
Interview: Delayed swelling (6-24hr) with effusion. Clicking or locking. Giving away. Some patient may describe a tearing sensation.
PE: McMurray’s test - palpable or audible click/pain (positive finding can point to meniscal, but neg cannot rule out). Joint line tenderness (45-90) - patients pain (positive finding is specific and sensitive). Apleys test - Pain (little worse than McMurrays in that is is somewhat specific and sensitive)
MCL
Interview: If the sprain is quite deep then immediate swelling can occur but if it is superficial then no swelling.
PE: Valgus stress test at 30 - pain is best factor but laxity is also very sensitive (grade of tear will determine laxity).
LCL
Varus stress test at 30 - looking for pain and laxity
Acute injuries
Specific/sudden MOI which often involves high force load.
Traumatic event which occurred at specific time point.
Amount of dysfunction is directly linked with injury severity (speed/amount of swelling can also indicate this)
Ligament injury PI
Specific/sudden MOI which often involves high force load.
Traumatic event which occurred at specific time point.
Amount of dysfunction is directly linked with injury severity (speed/amount of swelling can also indicate this)
Ligament injury PE
Ligament stress test (pain reproduction, end feel and laxity)
Grade 3 may have les pain, particular on stress test, due to limited nociceptors (only if isolated ligament strain, ACL sees this) but normally other tissues provoke pain inn presence of G3
Palpation over specific ligament (pain)
Swelling around ligament
Test for joint effusion if intra-articular (swipe/sweep test)
Fracture PI
High impact load (intrinsic or extrinsic)
Pain local to specific bony area
+/- pain with ice
Audible ‘break’ (crack or pop)
Inability or limited ability to WB
Quick onset and significant swelling, bruising, highly vascular
+/- deformity (only if on scene, this will be fixed soon after)
Fracture PE
Pain on palpation of bone, at suspected fracture site
Ottawa ankle/knee rule
Tapping, vibration, compression away from fracture site causing pain
