Overview
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 present.
- Bone proliferation results in an irregular, “fuzzy” appearance to the bone around the affected joint
- Periostitis: may appear 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: a severe form of either psoriatic arthritis caused by marked bony resorption and the consequent collapse of soft tissue; when this affects the hands, it can cause a phenomenon sometimes referred to as "telescoping fingers"
- Ivory phalanx: classically involving the distal phalanx of the great toe
- Sacroiliitis: often asymmetrical
- Spondylitis: asymmetric paravertebral ossifications and relative sparing of the facet joints
