Slide 1-

Arthritis of the Hand and Fingers Thomas A. Wiedrich, MD 1st Edition author: Donald H. Lee, MD
Slide 2-

Etiology of Arthritis of the Hand and Fingers Osteoarthritis Inflammatory arthritis Systemic Lupus Erythematosus Psoriatic arthritis Scleroderma Gout Pseudogout Post-traumatic Post-infectious Arthritis – Hand & Fingers
Slide 3-

Most commonly affected joints Distal interphalangeal joint (DIP) Thumb carpometacarpal joint (CMC) Proximal interphalangeal joint (PIP) Metacarpophalangeal (MP) joint rarely involved Incidence in > 65 year olds 78% of men / 99% of women Arthritis – Hand & Fingers
Slide 4-

Interphalangeal Joint Arthritis Often painless Deformities Angular Rotatory Marginal osteophytes Distal interphalangeal joint Heberden’s nodes Proximal interphalangeal joint Bouchard’s nodes Essentials of Hand Surgery 2002

Slide 9-

Nonsurgical Treatment of Mucous Cysts Rest Activity restriction/modification Splinting Anti-inflammatory medications Aspiration/Injections Arthritis – Hand & Fingers
Slide 10-

Surgical Indications Pain Deformity Painful instability Problematic mucous cyst Resistant to conservative measures Aspiration with ~ 40-50% recurrence Nail ridging Progressive enlargement Repeated local trauma Infection Arthritis – Hand & Fingers
Slide 11-

Surgical Options- Mucous Cyst Dependent upon symptoms as well as amount of arthritic changes within joint Simple Mucous cyst excision Osteophyte excision Joint debridement Minimal surgical complications, nail ridging can resolve in ~5/6 of cases Joint significantly affected by arthritis Arthrodesis Arthritis – Hand & Fingers
Slide 12-

Surgical Implant Options Tension band construct Intraosseous Kirschner wires (90-90 configuration Headless compression screw Position of arthrodesis Depends on fixation method and limitations with screw based on AP diameter of distal phalanx. Between 10-30° (0-10° more likely with screw, increasing flexion with K-wires) More flexion in ulnar digits Arthritis – Hand & Fingers

Slide 15-

Time to clinical union ~ 6 weeks, protect with thermoplastic splint until that time Radiographic union in ~3 months Results Nonunion rates vary between 0 and 10% depending on joint fused (PIP vs DIP respectively) Infection rate <5% (minor infection, though osteomyelitis may occur) Soft tissue problems More common over DIP than PIP Avoid by not closing wound too tightly, noncompressive dressings Arthritis – Hand & Fingers
Slide 16-

PIP Joint Arthritis Arthritis – Hand & Fingers
Slide 17-

PIP Joint Arthritis Less frequently affected by primary OA Typically, Post traumatic Inflammatory (RA) Post infection Presentation PIP joints become painful and stiff with marked decreased range of motion Arthritic process can render PIP joint unstable due to attenuation of soft tissue stabilizers Courtesy of Donald H. Lee, MD Arthritis – Hand & Fingers
Slide 18-

Regional Review Course 1998 Surgical Indications Pain Deformity Contracture Instability Surgical options Arthrodesis Arthroplasty Arthritis – Hand & Fingers
Slide 19-

Surface Preparation and Shaping Cup and cone Allows rotational correction at time of fixation Chevron Angled resection Methods of fixation Kirschner wires Tension band construct Intraosseous screws/wires Plate and screws Position of arthrodesis More flexion as one goes ulnarly to mimic cascade Arthritis – Hand & Fingers Leibovic S et al, JHS, 2007
Slide 20-

PIP Joint Arthrodesis With Headless Compression Screw Technical point Use rongeur to enlarge hole in middle phalanx to the size of proximal screw threads to prevent fracture of dorsal cortex! If dorsal cortex is breached, must use different method of fixation or supplement this fixation Arthritis – Hand & Fingers Leibovic S et al, JHS, 2007
Slide 21-

Converts palmar pull of flexors from distration force of dorsal side to compression force at palmar side Courtesy of Donald H. Lee, MD K-wire tension band construct
Slide 22-

Arthroplasty Indications Older population Primary or post traumatic arthritis Contraindications Infection Lack of flexor/extensors Severe periarticular bone stock loss Incompetent collateral ligaments Incompetent volar plate Poor soft tissue coverage Arthritis – Hand & Fingers
Slide 23-

Approaches Dorsal (central slip at risk) Tendon splitting Chamay tendon reflecting approach Lateral (collateral ligaments at risk) Volar (volar plate/flexor tendons at risk) Arthritis – Hand & Fingers Bickel KD, JHS, 2007
Slide 24-

Surface Replacement Arthroplasty Arthritis – Hand & Fingers Murray P, JHS, 2007
Slide 25-

Postoperative regimen Must protect central slip/lateral band/volar plate depending upon approach for 6 weeks. Use appropriate splint for approach(ie dynamic extension splint with flexion block for dorsal approach) Results after either Resurfacing Arthroplasty or Silicone arthroplasty Can expect excellent pain relief No real increases in ROM Appearance may be better with resurfacing Complications Extensor lag, instability of joint, need for reoperation/loosening Squeeking with resurfacing arthroplasty Branam and co-authors found 8/19 squeeked! (but patients were still happy with outcome and would opt for the same procedure) Arthritis – Hand & Fingers
Slide 26-

Thumb Carpometacarpal (CMC) Joint Arthritis Arthritis – Hand & Fingers
Slide 27-

Incidence Framingham cohort study showed symptomatic OA in 7% women and 5% of men > 70 yo (Zhang et al, Am J Epidemiology 2002) Prevalence of hand arthritis approaches 67% in women > 55 yo with 21%-36% occurring at the thumb CMC joint (Dahaghin et al, Ann Rheum Dis 2005)
Slide 28-

Clinical Symptoms Pain Palmar sided Pain with pinch Deformity Subluxation of the metacarpal dorsoradially with attenuation of the volar beak ligament Thumb metacarpal assumes adducted position MP joint extended Arthritis – Hand & Fingers
Slide 29-

Essentials of Hand Surgery 2002 Physical Examination Visual inspection Shoulder sign- subluxation of metacarpal dorsoradially MP joint may be hyperextended (thought to be compensatory, may be contributory to the process) Examine bulk of thenar musculature (association with carpal tunnel syndrome) Palpation/provocative maneuvers Grind test Examine mobility of MP joint May need to be addressed surgically at time of CMC procedure Examine for CTS Regional Review Course 1998 Arthritis – Hand & Fingers
Slide 30-

Differential Diagnosis Radial sided pain Intersection syndrome- pain with wrist flexion and extension DeQuervain’s tenosynovitis- Finkelstein’s maneuver Radial impaction- pain with radial deviation Scaphoid injury acute/chronic- pain/swelling in snuffbox, over tuberosity Scapholunate ligament injury- dorsal sided wrist pain, scaphoid shift test Scaphoid-trapezium-trapezoid arthritis- tenderness to palpation just distal to scaphoid Stenosing tenosynovitis- volar sided pain at A1 pulley level, nodule. Arthritis – Hand & Fingers
Slide 31-

Regional Review Course 1998 Eaton Classification of Thumb CMC Arthritis Stage 1 – Articular contours normal; joint space may be widened due to synovitis. Less than one-third subluxation on any view Stage 2 – Slight narrowing of the joint space with osteophytes < 2 mm in size. May have more than one-third subluxation of the joint surfaces Stage 3 –CMCJ narrowing with sclerotic or cystic changes, osteophytes > 2 mm. The STT joint remains intact Stage 4 – Pantrapezial arthrosis – CMCJ and STT joint severe articular degeneration Stage 3/4
Slide 32-

Regional Review Course 1998 Non Operative Treatment Splints Hand or forearm based NSAID’s Must be selective in older patients Injections Randomized controlled study comparing placebo to corticosteroid injection found no difference. Bay et al- prospective trial of injection and splinting evaluated effectiveness of 1 steroid injection and splinting x 3 weeks. Effective in stage 1 disease, less effective in stage 2/3 and ineffective in stage 4 disease. Arthritis – Hand & Fingers
Slide 33-

Regional Review Course 1998 Surgical Indications Pain Refractory to nonoperative treatment Interferes with pinch and grip Deformity Breadth of palm increases Base of the thumb is the most operated upon joint (for osteoarthritis) in the Western world. Shoulder sign MPJ hyperextended Arthritis – Hand & Fingers
Slide 34-

Surgical Options Dependent upon stage of disease Stage I Ligament reconstruction Metacarpal extension osteotomy Stages II-IV Ligament reconstruction with or without tendon interposition CMC arthrodesis Arthritis – Hand & Fingers
Slide 35-

Stage I Ligament reconstruction 30 degree metacarpal extension osteotomy Shifts forces dorsally away from arthritic changes on volar surface Koff MF et al, JHS, 2006
Slide 36-

Many options for Stage II-IV disease Some interpose tissue within the trapezial space, others use “hematoma arthroplasty” All are predicated on reconstruction of the volar beak ligament Arthritis – Hand & Fingers Mo JH et al, JHS, 2004

Thumb MCPJ Hyperextension Deformity < 10 degrees Leave alone > 10 degrees K-wire fixation in 10 degrees of flexion (6 weeks) Extensor pollicis brevis tenotomy and tenodesis to APL (removes deforming force from thumb proximal phalanx) and K-wire fixation Volar capsulodesis MP arthrodesis (arthritis) Arthritis – Hand & Fingers
Slide 39-

Clinical Outcomes After Treatment Of Thumb CMC Arthritis Ligament reconstruction Eaton et al reported 100% good/excellent results for stage I, 91% for stage II with 7 year follow up Metacarpal osteotomy Hobby et al reported good to excellent results in 95% of patients with low rate of complications Meta-analysis by Martou found no significant benefit to ligament reconstruction Latest Cochrane review shows trapiezectomy alone to be efficacious and safe Thumb CMC arthrodesis Younger patients with higher demands? Perhaps stronger pinch Relatively high rate of nonunion- asymptomatic Arthritis – Hand & Fingers
