Therapy Post CMC Joint ArthroplastyTherapy Post CMC Joint Arthroplasty
• Goals of treatment– Maintain thumb webspace– Maximize thumb ROM– Decrease pain and sensitivity– Strengthen the thumb– Return to usual daily functioning

Post-op ImmobilizationPost-op Immobilization
TWH protocol:Forearm based POP, thumb IP joint free, 3-4 weeks.
Variations:Poole and Pellegrini, thumb IP included, 4 weeks.Roberts et. al., bivalve, thumb IP free. Ulnar portion discontinued at 10 days, radial gutter to 3 weeks
SplintSplint
TWH:
Forearm based thumb spica with IP free. Start weaning off at 6 weeks.
Variations:
Poole and Pellegrini, splint as above for 3 months.
Brach, as above, thumb in maximum abduction. Wean off 8-10 weeks.
ExerciseExercise
TWH:
Week 3-4, AROM wrist and thumb within pain limits.
Variations:
Poole and Pellegrini, Week 5-AROM wrist and thumb MCP and IP. Block basal joint.
ExerciseExercise
Variations:
Roberts et. al., Week 3- AROM wrist and thumb, 3-4 times daily.
Brach, Week 4- wrist and thumb MCP and IP AROM. Home program includes isometrics for thumb abduction and extension performed in the splint.
ExerciseExercise
TWH:
Week 6- PROM wrist and thumb joints.
Variations:
Week 7-8, Poole and Pellegrini,
isometrics for thumb,
thumb setting
opposition
ExerciseExercise
Variations:
Brach, Week 5- AROM thumb opposition and composite flexion.
StrengtheningStrengthening
TWH:
Week 6- grip and pinch strengthening, therapyputty.
Variations:
Poole and Pellegrini, not till week 9.
Roberts et. al., isometrics and active resisted.
Brach, gripping at week 8.
Activity LevelActivity Level
TWH:
Light activity started at week 6. Increase within patient’s tolerance.
Variations:
Roberts et. al., Week 3- light activity initiated.
All:
Unrestricted work and activity permitted 4 to 6 months.
ModalitiesModalities
TWH:
Scar Management
massage
silicone gel inserts
desensitization, including immersion, contact and fluidotherapy
Edema Management
coban
isotoner glove
ComplicationsComplications
• Prolonged post-op pain
• CRPS
• Hypersensitivity of scar
• Palmar fasciitis
OutcomesOutcomes
1. Aggregate grip and pinch strength 20% improvement at 2 years post surgery with continued improvement to 6 years.
2. Grip, pinch, self reported ADL and pain all improved significantly at mean follow up of 1 year, 11 months. Patients did not reach maximum improvement until second year.
Summary of Key Points for TherapySummary of Key Points for Therapy
• Splint should position the thumb in maximum abduction
• Avoid CMC joint motion in initial weeks of treatment
• Avoid lateral pinch in first month of therapy, modify pinch activities later
• Desensitize scar if necessary• Educate patient regarding time frame for
outcomes
Literature Review for CMC Joint Literature Review for CMC Joint ArthroplastyArthroplasty
• 14 articles reviewed, 1986 to 2003, numerous procedures described
• 12 retrospective; 2 prospective ( Hematoma and Distraction Arthroplasty, Kuhns, 2003; Swanson vs APL arthroplasty, Tagil & Kopylov, 2002)
Literature Review (Cont’d)Literature Review (Cont’d)
• Outcomes evaluated– Pain– ROM– Satisfaction– Grip strength– Tip pinch strength– Key/lateral pinch strength– Radiographic changes– Jebsen– Moberg pick up test– Purdue Peg Board– ADL- self report– AIMS
Literature Review (Cont’d)Literature Review (Cont’d)
• Follow up 12 months to 9 years
• Results– Complete pain relief 73-97%– Significant post op pain up to 26%– Heavy work painful 50% – ROM similar to non-operated hand– Grip improved more than pinch, equal to non-
operated hand
ResultsResults
– Satisfaction related to pain relief
– Self reported ADL better than observed performance on Jebsen
– Moberg, no difficulties
– Radiographic changes included subsidence, subluxation
ResultsResults
• Complications
– Radial sensory nerve numbness– Scar tenderness– RSD
ResultsResults
• Better in age 60 and over
• Gains in ROM first
• Continued improvement in pain relief and strength from 2 to 6 years
• Loss of key pinch after 6 years
RecommendationsRecommendations
• More prospective studies
• Use of standardized functional performance tests
• Use standardized protocol for measuring ROM and strength
