40
What is seen here? In what condition is this seen?
Pencil-in-cup appearance Psoriatic arthritis
41
Psoriatic arthritis Ix
XR: erosive changes new bone formation periostitis pencil-in-cup appearance
42
Psoriatic arthritis Mx
Managed by rheumatologist Mild: NSAID Mod/ severe: Methotrexate Biologics e.g. Ustekinumab
43
What is the most common cause of heel pain in adults?
Plantar fasciitis Worse around medial calcanea tuberosity
44
Mx of plantar fasciitis
Rest feet where possible Wear shoes with good arch support + cushioned heels Insoles + heel pads
45
Scaphoid fracture S/S
FOOSH/ contact sports Pain along radial aspect of wrist, at base of thumb Loss of pinch/ grip strength Max. tenderness over anatomical snuffbox Wrist joint effusion
46
What is seen here?
Scaphoid fracture
47
Scaphoid fracture management
Immobilisation: futuro splint/ below-elbow backslab Refer to orthodox: further imaging within 7-10 days Undisplaced: cast 6-8w Displaced/ proximal scaphoid pole: surgical fixation
48
Complications of scaphoid fracture
Non-union: pain + early OA Avascular necrosis
49
Innervation of thenar muscles
Median nerve
50
Innervation of hypothenar muscles
Ulnar nerve
51
Tests for carpal tunnel syndrome
Tinel's sign: tapping causes paraesthesia Phalen's sign: flexion of wrist causes Sx
52
Carpal tunnel syndrome S/S
Pain/ pins + needles in thumb, index + middle finger Patients shake hand to obtain relief Weakness of thumb abduction Wasting of thenar eminence
53

55
What is seen here?
Unicompartmental knee replacement
56
What is seen here?
Total knee replacement
57
Indication for unicompartmental knee replacement. Positives and negatives
OA limited to a single compartment +ves: less invasive, quicker rehab -ves: highly specialised, likely going to need to replace other compartment
58
Indication for total knee replacement. Positives and negatives
OA affecting all knee compartments +ves: well established, no progression of OA, less specialised -ves: more invasive, slower rehab
