  • Periscaphoid: DISI
  • DRUJ instability
  • MCP joint disease
  • Ext tenosynovitis
  • Flexar tenosynovitis
    • tendon rupture
    • Trigger
  • CTS
  • Thumb
  • Swan and bout

Wrist

  • Volar subluxation of carpus
    • Volar carpal lig laxity
  • Caput ulna leading to vaughan jackson
    • Volar subluxation of carpus
    • ECU subluxation
    • DRUJ disease

Metacarpals and MCPJ

  • Radial deviation

    • Altered pull of EDC
    • Capsular laxity

Intrinsic imbalance

  • Boutonniere
  • Swan neck
  • Ulnar deviation of fingers
    • Radial collateral lig weakness causing volar ext tendon subluxation

Dropped fingers

  • PIN
  • Tendon rupture
  • Tendon subluxation

Inability to flex DIP

  • FDP rupture
  • FDP FDS adhesion
  • Trigger

Assessment

  • Look:
    • Screen neck, shoulder and elbow
    • Describe deformities
    • Swellings
    • Scars
    • Muscle wasting
  • Move active
  • Feel: Swellings
  • Functional assesment

Functional assessment

  • Power grip
  • Tripod: Pen
  • Key
  • Precision: Coin

Rheumatoid surgery

  • Lower limb first
    • Forefoot first if hind foot flexible
    • Hind foot first if not flexible
  • Upper limb proximal first then distal
  • Urgent procedures
    • Nerve compression
    • incipient tendon rupture

Common procedures

  • Wrist arthrodesis (arthroplasty)
  • DRUJ fusion/ excision
  • MCPJ arthroplasty
  • Thumb MCPJ arthrodesis

Wrist arthroplasty

  • Prerequisites
    • Ext tendons intact
    • Minimal deformity
    • Adequate bone stock
    • No infection
    • Other side arthrodesis

Reconstruction tendon rupture

Problem Procedure
FDS None
FDP wrist Tenodesis
FDP finger DIP fusion
FDS and FDP FDS other finger
FPL IP fusion

Vaughen Jackson

  • Darrach + synovectomy for pre rupture
  • Little F: suture to RF
  • LF and RF: suture to MF
  • MF, RF and LF:
    • EI to RF and LF
    • MF to IF
  • All
    • FCR transfer

Mannerfelt

  • FPL
  • Tenosynovitis of Scaphotrapezial region

Rheumatoid thumb

Key points

Column 1 Column 2 Column 3 Column 4 Column 5
Nalebuff Problem Location Treatment
1 Boutonniere MCPJ extensor hood attenuation Flexed MCP, extended IP MCP fusion
2 1+ CMCJ dislocation MCP fusion
3 Swan neck CMCJ disease Subluxated CMC; Adducted thumb MC; Extended MCP compensation; IPJ flexion Trapezectomy and MCP fusion
4 Gamekeeper thumb UCL rupture Adduction contracture MCP fusion
5 MCPJ hyperextension Volar plate MCP fusion

Boutonniere finger

Pathology

  • PIP joint extensor aspect
  • Attenuation of central slip
  • Disruption of triangular lig
  • Volar subluxation of lateral band

Classification Nalebuff

  • Mild: <15 degree ext lag correctable (Splint)
  • Moderate : > 15 degree lag with some contracture (Central slip reconstruction)
  • Severe: FFD (Arthrodesis)

Capner splint for boutonnière

Swan

Pathology

  • Imbalance of forces at PIP joint or lax volar plate leading to loss of flexion at PIPJ , hyperextension at PIPJ and Flexion at DIPJ

Classification

Murphy splint
