Overview
Psoriatic arthritis may lead to erosion of bone tissue and characeristic "pencil in cup" deformities. It may also lead to periostitis, dactylitis or arthriris mutilans.
X-Ray
- Key X-ray findings in psoriatic arthriris include:[1][2][3]
- Enthesitis and marginal bone erosions.
- "Pencil-in-cup" deformities.
- Interphalangeal ankylosis may be found.
- Bone proliferation leads to inflammatory bone spur formation around the affected joints.
- Periostitis: Appears as a periosteal layer of new bone, or as irregular thickening of the cortex itself.
- Dactylitis: which can present as a “sausage digit” which refers to soft tissue swelling of a whole digit.
- Arthritis mutilans: It may lead to "telescoping of fingers" caused by marked bony resorption and the subsequent collapse of soft tissue
- Asymmetrical sacroilitis
- Spondylitis: Asymmetric paravertebral ossifications and relative sparing of the facet joints.
