Tendon involvement and its association with pain and hand function in patients with osteoarthritis of the hand
Authors' conclusion
This study revealed a high frequency of tendon involvement in hand OA. Tendon involvement on US did not impact hand function or self-reported pain.
Study context
- Population
- Patients with hand OA and age- and sex-matched controls; extensor and flexor tendons of both hands assessed by clinical examination and US
- Participants
- 86 vs 23
- Exposure
- Hand OA vs age- and sex-matched controls
- Hand OAn = 86
- Controln = 23reference
- Outcome
- Frequency of tendon involvement (tenosynovitis and tendon damage) on US and its influence on pain and hand function
Methodological detailsage- and sex-matched controls, clinical examination and US, K-means cluster analysis
- Age- and sex-matched controls
- Clinical examination and US
- K-means cluster analysis
Main finding
As reported in the abstract
Involvement of one or more tendon on US
P < 0.01
Observational data: associations, not effects.
Further findings
Tendon damage on US, flexor vs extensor tendons (hand OA)
- Flexor tendons
- 2.1%
- Extensor tendons
- 0.9%
- Flexor vs extensor
- P = 0.03
Tenosynovitis on US, extensor vs flexor tendons (hand OA)
- Extensor tendons
- 8%
- Flexor tendons
- 0.6%
- Extensor vs flexor
- P < 0001
Clinical examination vs US for detecting tendon involvement
- Sensitivity, patient level
- 81.4%
- Specificity, patient level
- 34.6%
- Sensitivity, tendon level
- 14.5%
- Specificity, tendon level
- 83.8%
Cluster analysis
- One cluster with more radiographic features of hand OA and more tendon damage; more tenosynovitis in cluster 2
M-SACRAH function vs tendon involvement on US
- No correlation
