Reducing basal thumb joint distraction duration to 6 weeks may maintain treatment benefits for thumb carpometacarpal osteoarthritis (CMC1 OA). This study investigates if a shorter 6-week distraction period is as effective as 8 weeks for improving function and reducing pain in CMC1 OA patients.
Area of Science:
- Orthopedics
- Hand Surgery
- Rheumatology
Background:
- Thumb carpometacarpal osteoarthritis (CMC1 OA) affects many patients, with joint distraction showing promise for symptom relief.
- Previous studies indicate joint distraction improves physical function and reduces pain in CMC1 OA patients, with low rates of subsequent surgery.
- This research explores optimizing CMC1 joint distraction treatment duration.
Purpose of the Study:
- To determine if a 6-week CMC1 joint distraction is non-inferior to an 8-week duration for physical function outcomes.
- To evaluate secondary outcomes including pain, patient satisfaction, and adverse events at one year post-treatment.
- To assess the safety and efficacy of reduced duration for CMC1 joint distraction.
Main Methods:
- A monocenter randomized controlled non-inferiority trial comparing 6-week versus 8-week CMC1 joint distraction.
- Inclusion criteria: patients under 65 with symptomatic CMC1 OA and surgical indication.
- Primary outcome: physical function at one year; secondary outcomes: pain, satisfaction, strength, range of motion, and radiographic changes.
Main Results:
- The study aims to establish non-inferiority of 6-week distraction compared to 8-week distraction for physical function.
- Analysis will include differences in pain intensity, patient satisfaction, hand health, adverse events, and treatment failure.
- Thumb strength and range of motion, along with radiographic changes, will also be compared between groups.
Conclusions:
- Reducing CMC1 joint distraction to 6 weeks could decrease patient burden while maintaining therapeutic benefits.
- This trial will enhance understanding of potential adverse events associated with this relatively new treatment.
- Findings will aid informed decision-making for patients considering CMC1 joint distraction and guide future comparative studies.
