Question 2

Q

In cardiac exam - what should I not forget?

Answer

A

Hands/arms:

CRT, clubbing, arm bruising
Radio-radial delay
Collapsing pulse (lightly palpate radial and brachial pulses –> feel stronger for a few pulses) = AR
BP standing/sitting

Head/neck:

Check for carotid bruits before taking carotid pulse (character, volume) - slow rising = AS, bounding = AR

Question 4

Q

Neuro examination Qs:

Good acronym for general inspection?
What screens do you do for upper and lower limbs?
What are you feeling for on examining tone?
What to do before checking power against resistance?
How to find the tendon for each reflex?
How do you accentuate neuro reflexes?
What to remember when doing the finger-to-nose test?

Answer

A

SWIFT - scars, wasting, involuntary mov, fasciculations, tremors
Screens:
- Upper - hands out pronate (tremor?), supine hands and close eyes (pronator drift = UMN lesion)
- Lower:
  - Stand up from chair with hands crossed (prox power)
  - Gait assessment - normal, only on heels/toes (distal power), tandem walk (balance)
  - Stand with both feet together (balance) –> Romberg’s test if they could do prior (eyes closed - proprioception).
Tone:
- “Clasp-knife spasticity” = pyramidal (UMN) lesion - velocity/direction-dependent e.g. stroke/spinal cord compression/MND
  - CLONUS also present in UMN lesion
- Rigidity = extrapyramidal lesion - velocity/direction independent, types:
  - “Lead-pipe” = NMS (anti-psychotics)
  - “Cogwheeling” = Parkinson’s (tremor on rigidity)
Check power against gravity - raise arms/legs (if so MRC is 3+)
Eliciting reflexes:
- Biceps - thumb over cubital fossa (from lateral side) while they move hand towards shoulder (should be central) - place nail over tendon and hit nail. Get patient to rest hand on knee
- Brachioradialis - first 2 fingers 1/3 up arm from wrist, lateral arm. Get patient to rest hand on knee
- Triceps - hold out patient arm at 90 degrees takin the weight of the patient’s arm, stand behind patient, hit just above the olecranon
- Knee jerk - if patient supine, support behind knee
- Ankle jerk - if patient supine, cross one leg over the other, dorsiflex foot, strike ankle tendon OR keep straight, dorsiflex foot and strike ball of the foot (just below ball under toes)
Jendrassik maneuver - clench hands together/clench jaw at the same time as eliciting reflex
Put finger just beyond reach so they have to stretch

Question 5

Question 10

Q

Knee examination? Presentation? Ddx structure? Ix? Common pathologies?

Answer

A

Intro - WIPE (wash, intro, pain & position, explain)

Function - Gait (Antalgic, waddling = abductor dysfunction)

Look:

General - RASS (Redness, Asymmetry, Swelling, Scars)
Standing up - front (quads wasting, knee swelling), side (fixed flexion deformity, foot arches), back (varus/valgus deformity, baker’s cyst)
Lying on bed - scars (TKR, arthroscopic ports on either side), wasting, deformity

Feel:

TST (Temperature, Swelling, Tenderness)
Effusion:
- Patellar tap (push down thigh & hold, press down on patella with middle finger)
- Sweep test (push down thigh, back of hand sweeps up medial x3, other back of hand sweeps down lateral, +ve is swelling on the medial side)
Palpation:
- Leg straight - quadriceps tendon, medial & lateral borders of patella, patella tendon
- Knee @90 degrees:
  - Patella tendon, tibial tuberosity (down from tendon), medial joint margin
  - Lateral joint margin, head of the fibula (slightly lateral and distal to knee), collateral ligaments (hands around upper calf)

Move (active > passive - feel for crepitus, get a few more degrees)

Knee extension:
- Active = push knee down into bed
- Passive = lift entire leg up @ ankle (hyperextension >10 degrees)
Knee flexion:
- Active = bring heel towards bum (posterior sag?) then straighten
- Passive = same mov, leave knee flexed (for next part)

Special tests = 3Cs of knees – Cartilage (McMurray’s), Collaterals, Cruciates – Lachman’s, A/P-drawer)

Anterior & posterior drawer (ant- bring towards = ACL; post - push away = PCL)
Lachman’s test (flex knee to 30 degrees, right hand pulls, left hand stabilises the femur, checks ACL)
Collateral ligament assessment:
- Varus stress test (LCL) - put the knee in varus positon while palpating the lateral knee joint line
- Valgus stress test (MCL) - put the knee in valgus position while palpating the medial knee joint line
Menisci assessment - McMurray’s test - say “would consider doing but may be too painful for the patient”
- Passively flex the knee, hold the right foot with right hand apply external pressure with the left hand palpating the knee (abducting at the hip) while fixating and external rotating with the right hand, slowly extend at the knee watching for a click/discomfort = medial meniscus tear
- Opposite movements to test for lateral meniscus tear

To complete exam:

Assess NV status
Examine joints below and above (hip and ankle)
Further imaging if indicated (X-ray)

Presentation:

Normal gait, no obvious deformities of either knee, on palpation there was no pain and there was a full range of active and passive movement
There was no evidence of laxity in the knee ligaments bilaterally

DDx: degenerative, infective, inflammatory, traumatic, congenital

Ix: AP & lateral views (2 views) + imaging of joints above and below as well

Common pathologies:

ACL tear - twisting injury, ‘pop’ swelling within 1 hour, very painful for 2wks
- Increased laxity on anterior drawer test/Lachman’s test
- Mx: physio/surgical reconstruction (if ongoing instability)
PCL tear - high energy trauma (multi-ligament knee injury/hip dislocation/fracture)
- Increased laxity on posterior drawer test
- Mx: physio/surgical reconstruction
Meniscal tear - twisting injury, swelling after a few hrs, sharp localised medial/lateral pain worse on hyperflexion/twisting, knee may lock/give way
- Tender over medial/lateral joint line, good RoM unless knee locked, +ve McMurray’s
- Mx: MRI/arthroscopy to confirm, tear usually excised arthroscopically
Collateral ligament tear
- Varus/valgus laxity, effusion, tenderness over affected ligaments
- Mx: rest, physio, hinged brace
OA - pain & stiffness, reduced RoM, crepitus
Prepatellar bursitis - localised swelling over patella, precipitated by period of kneeling
- Signs: tender over patella, normal RoM
- Mx: rest, NSAIDs, aspiration/CS inj

Question 11

Q

Hip examination? Presentation? DDx structure? Ix? Mx (for OA)? Common pathology?

Answer

A

Intro - WIPE (wash, intro, pain & position, explain)

Function - Gait (Antalgic, Trendelenburg - waddling = abductor dysfunction)

Look

General - RASS (Redness, Asymmetry, Swelling, Scars)
Standing inspection:
- Front (pelvic tilt, quads wasting), side (lumbar lordosis, knee flexion, foot arches), behind (scoliosis, gluteal atrophy, iliac crest alignment)
- Trendelenburg’s test:
  - Place hand resting lightly above both hips
  - Bend one knee - if the hip dips on the bent side = contralateral abductor muscle weakness
Lying inspection: compare symmetry & rotation (shortened & externally rotated = fractured NoF), hip scars, dressings, skin changes

Feel - check for pain, start on the normal side

TST (Temperature, Swelling, Tenderness)
Bony landmark tenderness:
- Feel around hip joint (tenderness, warmth, effusion)
- Feel along greater trochanter (lateral edge of thigh - trochanteric bursitis) run a hand up to greater trochanter (trochanteric bursitis)
- Feel ASIS –> pubic rami
Measure true/apparent leg lengths:
- Apparent = umbilicus to medial malleolus (unequal = spinal/pelvic deformity e.g. scoliosis)
- True = ASIS to ipsilateral medial malleolus (unequal = true limb shortening e.g. fracture)

Move (active > passive - feel for crepitus, get a few more degrees)

Roll side to side
Flexion:
- Active (as far as can) then passive feeling for crepitus
- Passive internal & external rotation (while knee is bent to 90 degrees, lose IR early in OA)
Passive abduction & adduction - place a hand on the contralateral pelvic crest to detect mov (crossing over leg for adduction)
Passive extension - lie face down, scars/muscle wasting? place hand on pelvis/lumbar spine to detect mov

Special tests

Thomas’s test (not if hip replacement –> dislocation):
- Place a hand under the lumbar spine (check no lumbar lordosis)
- Flex hip on one side (knee bent)
- If contralateral thigh forced off the ground = fixed flexion deformity (of the side forced off the ground)
- NOTE: need to flex hip on the opposite side to that examining

To complete exam - examine shoulder and knee, full neurovascular exam distal to joint

Presentation:

Normal gait, no obvious deformities on inspection
On palpation, there was no pain with a full range of passive and active movement and no fixed flexion deformity and no abductor muscle weakness

DDx: degenerative, infective, inflammatory, traumatic, congenital

Ix: AP & lateral views (2 views) + imaging of joints above and below as well

Mx (for OA):

Conservative – physio, exercise, weight loss
Medical – analgesia, IA CS injection
Surgical – arthroplasty

Common pathology:

Hip OA - pain, crepitus, reduced ROM (internal rotation lost first)
Hip fracture - shortened and externally rotated limb
Hip dislocation - shortened and internally rotated limb
Abductor muscle weakness - Trendelenburg’s positive
Trochanteric bursitis - pain over the greater trochanter
Childhood - dislocation, Perthes, SUFE

Question 12

Q

How do you approach an MSK X-ray?

Describing a fracture on XR approach?

Answer

A

MSK X-RAY APPROACH:

NOTE: likely knee or hip x-ray in the exam

General:

Name, DoB ±PC
XR - date & time, views (AP/lateral), area of body, rotation, penetration (RI_P_E)
NOTE: always do ≥2 views, compare to previous X-rays, look at imaging for joints above and below

ABCS approach: Alignment & joint space, Bone texture, Cortices, Soft tissues

Alignment & joint space:
- Changes suggest –> fracture, subluxation (still touch) or dislocation
- Displacement - describe the position of fragment distal to fracture site described
- Joint space:
  - Narrowing due to cartilage loss/calcification (chondrocalcinosis)/new bone (osteophytes)
  - Subchondral sclerosis is increased bone density along joint lines (OA)
Bone texture - altered density (subchondral cyst - increased density, OA)/disruption (blurry - osteomyelitis) in trabeculae (inside of bone)/cortex (outer coating)
Cortices - trace around outside of each bone
- Step = possible pathology:
  - Fracture
  - Bony destruction - inf or tumour (primary/secondary)
- Periosteal reaction (new bone in response to injury/stimuli, appears as pale bone on the outside) - can be only sign of stress/healing fracture, mild osteomyelitis, tumour)
Soft tissues - swelling, foreign bodies (lipohaemarthrosis caused by fracture), effusions

DESCRIBE A FRACTURE:

Where - what bone? location (proximal, middle, distal OR epiphysis, metaphysis, diaphysis)? Does it involve articular surface (intra/extra-articular)?

Types:

1. Simple vs Compound:

Simple: closed fracture i.e. only bone involved
Compound: open fracture i.e. bone exposed to the external environment - (↑risk of infection → ↑fracture non-union) Open fractures are emergencies and require urgent management with:
- IV antibiotics
- Tetanus prophylaxis
- Wound debridement

2. Subtype:

Complete (all the way through the bone)
- Transverse: perpendicular to long axis of bone
- Oblique: tangential to long axis of bone
- Spiral: oblique and rotating around the shaft
- Comminuted: > 2 fragments –> CT to further assess
- Impacted: broken ends of bone are jammed together by the force of injury, fracture line is indistinct
- Linear: parallel to axis of the bone
- Avulsion: bone attached to tendon/ligament is pulled away from main bone
Incomplete (not whole cortex, most common in children):
- Greenstick: bone bends and cracks, occurs < 10yrs
- Salter-Harris: growth plate involvement

Displacement - describe the position of distal fragment to body (anterior/posterior)

Angulation: change in bone axis (varus/valgus, dorsal/palmar, radial/ulna)
Translation: movement of fractured bones away from each other (% of bone width)

OVERALL: 1) Type (simple/compound > subtype) 2) Relevant region, side and name of bone 3) Displacement (& angulation, translation)

Example: Simple oblique fracture of the proximal right tibia with posterior displacement

Question 13

Q

Vascular exam - upper, abdo & lower? Arterial & venous anatomy?

Answer

A

NOTE: if press harder and it is there = my own pulse; if press weaker and it is there = their pulse

If can’t feel pulses can use doppler USS: triphasic signal
- 1st phase - forward rush of blood
- 2nd phase - reverse flow from elastic recoil (in arterial wall)
  - Lost in arterial disease = biphasic/monophasic signal
- 3rd phase - forward flow on vessel relaxing

EXAMINATION:

General inspection – smoking, inhalers, diabetic meds, fistula, dressings, walking stick

Upper:

Hands – splinter haemorrhages, nicotine stains, missing digits (more common in trauma, Buerger’s disease), temperature + CRT
Supra-aortic pulses:
- Radial – rate, rhythm, radio-radial delay
- Brachial pulse – character
- Subclavian pulse, in supraclavicular fossa
- Carotid pulse
BP
Listen for bruits in neck, breathe in and out slowly

Abdo:

Inspect for scars, look around sides
Palpate for aneurysms - abdominal aortic pulse
Listen for aortic and renal bruits (above umbilicus and to either side)

Lower:

Inspect (colour, swelling, scars, varicose veins)
Palpate:
- Temp in feet, calves, thighs (run back of hand along)
- Tenderness - squeeze ankles/calves (DVT)
- CRT, pitting oedema
- Measure leg diameter 10cm below tibial tuberosity (If <3cm between = not significant)
Femoral arteries (ASIS & pubic symphysis midpoint):
- Feel simultaneously as weak femoral pulse difficult to determine
- Radio-femoral delay
- Auscultate femoral pulse for bruits (can also listen to iliacs - below umbilicus on either side) –> sometimes only picked up on exercise
Popliteal arteries – reach around back of knee, behind the knee, slightly lateral, lift leg up to 30 degrees so weight resting on fingers
Pedal arteries – anterior (dorsalis pedis) & posterior tibial (behind medial malleolus)
BUERGER’S TEST (for peripheral vascular disease)
- Both feet held up – angle foot goes white is Buerger’s angle –> when foot blanches swing legs over side of bed and let them hand down –> ischaemic foot will go brick red = severe peripheral vascular disease of lower limb = SUNSET SIGN
- Ideally, I should hold feet for 1 minute but still say -ve test if no blanching
ABPI:
- BP cuff above ankle with leads upwards – find dorsalis pedis pulse with doppler USS
- Inflate cuff until signal disappears – let down cuff until signal reappears = ankle pressure
- Repeat procedure in arm using brachial artery signal to record the brachial pressure
- ABPI = ankle pressure/brachial pressure
- 0.5-0.8 = claudication (mild-moderate disease); <0.5 = rest pain (severe disease); <0.2 = gangrene

Finally - complete relevant neuro exam, vascular exam where not been done in exam, CV & abdo exams

Bloods - FBC, U&E, coag
D-dimer, duplex USS (venous - DVT/arterial - perfussion) –> CTPA (PE)
Tx: DOAC/Warfarin if high-risk DVT

Leg Anatomy:

Arterial:
- External iliac artery > femoral artery (pulse):
  - Profunda artery (minor branch)
  - Superficial femora artery (main branch) > Popliteal artery (pulse):
    - Anterior tibial artery - form dorsalis pedis artery (pulse)
    - Posterior tibial artery - goes around medial malleolus (pulse)
      - Peroneal artery (branch of PTA)
Venous:
- Great-saphenous vein (medial) - meets deep femoral vein in medial upper thigh (as goes into groin)
- Small-saphenous vein (lateral)
- Connected via perforating vein

Question 14

Q

Breast anatomy? Breast exam? Triple assessment?

Answer

A

Breast anatomy - Lobules > ducts > nipple

Ligaments suspending breast = Cooper’s ligaments
Most lymphatic drainage to axilla (& intercostal, interthoracic LNs)
Blood supply - perforating intercostal arteries

Intro - WIPE + chaperone

Inspection:

SITTING Positions:
- Relaxed arms
- Hands rested on thighs
- Hands-on hips - tense pectoralis
- Hands behind head - accentuate dimpling/asymmetry
- Lift breasts - submammary fold (ask patient)
Look for:
- Asymmetry, local swelling, scars (look under breasts)
- Skin changes:
  - Dimpling/puckering - tethering due to cancer
  - Peau d’orange - lymphatic oedema due to cancer
- Nipple changes:
  - Paget’s disease of breast - unilateral nipple = cancer
  - Eczema - areola (rarely nipple), bilateral
  - Inversion - normal variant/cancer

Palpation: LYING DOWN + hand on the side being examined behind head + check for pain (start on normal side)

Use palmar surface of middle 3 fingers to feel for any lumps starting in centre and going round in concentric circles
Pinch along axillary tail (first 2 fingers & thumb)
Ask patient to squeeze each nipple to check for discharge
Localise + describe lump: 3Ss, 3Cs, 3Ts
- Site, Size, Shape
- Consistency, Contours, Colour
- Tenderness, Temperature, Tethering/Transillumination
Lymph nodes:
- Axillary - ask patient to hold bicep:
  - Palpate apical, lateral, medial, anterior, posterior aspects
- Cervical LN exam
Offer to examine lungs and liver for mets

Triple assessment:
