A prospective study comparing outcomes after reconstruction in rheumatoid arthritis patients with severe ulnar drift deformities
Plastic and Reconstructive Surgery, 06/22/09

Chung k et al. – Study concludes that rheumatoid arthritis (RA) patients with more severe metacarpophalangeal joint diseases will attain similarly good outcomes after reconstruction when compared with those with less severe deformities.

Methods

Aim was to evaluate outcomes of RA pts with metacarpophalangeal joint deformities (subluxation and ulnar deviation) after silicone metacarpophalangeal joint arthroplasty
70 pts, categorized into 2 groups based on degrees of deformity: <100 degrees or ≥100 degrees
Outcomes were assessed at 6 mo and 1 yr based on:
- Michigan Hand Outcomes Questionnaire
- Grip/pinch strength
- Metacarpophalangeal joint deviation angles
- Jebsen-Taylor test, and
- Arthritis Impact Measurement Scales 2 questionnaire

Results

No difference in outcomes at 1-yr f/u between the 2 groups, after controlling for age, gender, and baseline values
Outcome scores were not different between the 2 groups
However, pts with more severe hand deformities had worse ulnar drift and extensor lag after reconstruction
