Q

What is the pathophysiology of OA

A
  • Abnormal articular cartilage
    • loss of PG, + cytokines, chondrocytes response to mechanical forces altered
  • Abnormal subchondral bone
    • w expousre, bone becomes sclertotic w cysts, osteophytes
  • Abnormal periarticular tissue
    • inflam of synovium, capsule, swelling/stiffness

Q

Describe your operative management of DIP OA

A

OPTIONS

  • Arthrodesis
    • Indicated: deformity/pain/loss fx
    • Key pts - need bone apposition/stock, fused at 0-5’
    • Adv: resolves pain/deformity, well toelrated as DIP contributes<15% of finger flexion
    • Disadv: loss of ROM
    • Points: H/Y incision, rongeur/osteotomy for perfect apposition, fixation w kwire,screw,interosseous wire at 0-5’ flexion
  • Arthroplasty
    • indicated as above and desire to maintain some flexion
    • Adv: maintained ROM
    • Disadva: joint instbaility, extrusion
    • silicone spacer - placed as above - average ROM 30’
  • Mucous cyst
    • aspiration - risk of septic arthritis, recurrence
    • Excision - risk of loss of ROM, nail deformity, septic arthrosis, recurrence

  • Adv: stable
  • DisAdv: loss of ROM - PIPjt responsible for 85% of digit and 20% hand flexion
  • dorsal longitudinal incision, splint extensor, rongeur/osteotomy or cup and cone
  • fuse index 40; long 45’, ring 50’, little 55’
  • Fixation: oblique lag, axial compression screw, herbert screw, interosseous wire, kwire, plate
  • Risk: loss of grip strength, non/mal union, pain infection

ARTHROPLASTY

  • Indicated: passive RO preserved, adequate bone stock
  • Adv: maintained ROM, av jt ROM 40-60
  • Disadv: infection, implant failure, instability, not achieving full ROM, peristent/recurrence deformity
  • Options
    • Swanson (interposition silicone spacer)
    • Pyrocarbon (surface/total jt replacement)
    • Therapy- 2wk cast, 4wk short arc

  • Salvage!!!! signifiicant disability from loss of ROM. For pain relief
  • Fusion angle index 25’, long 30’. ring 35’, little 40’

      *
19
Q

What is the pathophysiology of CMC thumb arthritis

A
  • Anterior volar oblique ligament Attrition
  • Ligament lixity
  • abnormal joint position/loading
  • biomechanical damage to articular surface
20
Q

What are special views for diagnosis of thumb CMC OA

A
  • Roberts view: AP of thumb with hand hyperpronated
  • TM stress view: bilateral radial thub tip aainst each other and 30’ PA
21
Q

What are operative interventions for Stage 1 CMC thumb OA

A
  • Goal: offload palmar cartilage, prevent further subluxation, stabilize joint
  • ARTHROSCOPY
    • Adv: minimally invasive
    • Disadv: may not provide benefit
    • Synovetcomy, debridment, volar thermal capsulorrhaphy
  • DORSAL WEDGE OSTEOTOMY
    • Adv: high pt satisfaction, improved grip and pinch strength, improved pain
    • Disadv: nil
    • transverse partial osteotomy 1cm distal to CMC jt, 2nd 30’ oblique 5mm distal to 1st. Extend and compress MC and kwire 6wks
  • VOLAR LIGAMENT RECON
    • Adv: improves pain
    • DisAdv; less effective for men
    • pass radial half of FCR through MC and secure to APL

What is your management of a patient with gout?

A

Hx

  • monoarticular painful jt, 50% involve 1st MTP.

Inv

  • early normal, late osteolytic lesions

TREATMENT

Non-op

  • treat acute attack w indomethacin, lower uric acid, longterm colchicine

Operative

27
Q

What is your management of a patient with Scleroderma?

A

Hx
