Summary
Psoriatic arthritis frequently affects the cervical spine, particularly the facet joints, leading to neck pain and potential C1-C2 subluxation. This study highlights key clinical and radiographic findings in affected patients.
Area of Science:
- Rheumatology
- Orthopedics
- Radiology
Background:
- Cervical spine involvement in psoriatic arthritis is not well-documented.
- Previous research is limited to a single case-control study.
Purpose of the Study:
- To investigate the clinical and radiographic features of cervical spine disease in psoriatic arthritis patients.
- To compare these features with a control group experiencing low back pain.
Main Methods:
- A case-control study involving 30 psoriatic arthritis patients and 30 controls.
- Clinical assessments included physical examination and functional questionnaires.
- Radiographic evaluation of the cervical spine (AP, lateral, flexion, extension views).
Main Results:
- Psoriatic arthritis patients reported significantly more neck pain (73% vs 26%) with an inflammatory pattern.
- Facet joint abnormalities (osteophytes, joint space loss, sclerosis) were more prevalent in patients, especially at C3-C4 and C4-C5.
- Anterior C1-C2 subluxation occurred in 10% of patients; syndesmophytes were absent.
Conclusions:
- Psoriatic arthritis commonly involves the cervical spine, targeting facet joints.
- The condition can lead to anterior C1-C2 subluxation.
- Further research is needed to correlate clinical and radiographic findings within the patient group.
