Eaton classification of radiographic stages of thumb CMC OA 1 - Normal appearance 2 - Joint space narrowing osteophytes < 2mm 3 - Sclerosis, Subchondral cysts osteophytes > 2mm 4 - Pantrapezial arthritis Regional Review Course 1998

Surgical Options - Excisional arthroplasty of trapezium - Excisional arthroplasty of trapezium with rolled tendon graft - Ligament reconstruction and tendon interposition arthroplasty (LRTI) - Trapezium excision and silicone implant - Hemiarthroplasty of the trapeziometacarpal joint - Total joint implant of trapeziometacarpal joint - Trapeziometacarpal arthrodesis

Thumb MCPJ hyperextension deformity < 10 degrees – no treatment 10 to 20 degrees – K-wire fixation in degrees of flexion (6 weeks) > 20 degrees – volar plat capsulodesis (no arthritis) – MP arthrodesis (arthritis)

Inflammatory Arthritis
Systemic disorder Skin rashes and ulcers Organ dysfunction Cardiac, pulmonary, renal, vascular, ocular, GI Hematological disorders Raynaud’s phenomenon More common disorders Rheumatoid arthritis Systemic lupus erythematosus Psoriatic arthritis Scleroderma

Summary Osteoarthritis commonly involves the hand, especially the distal and proximal interphalangeal and thumb carpometacarpal joints Rheumatoid arthritis commonly involves the metacarpophalangeal joints

Summary Non-operative treatment includes the use of antinflammatory medications, splints and therapeutic modalities Surgical treatment includes soft tissue reconstruction, arthroplasty and arthrodesis
