Scleroderma (musculoskeletal manifestations)
Musculoskeletal manifestations of scleroderma are common and variable.
For a general discussion of scleroderma, please refer to the parent article: scleroderma.
Imaging findings demonstrate bone and soft tissue changes. The hands are the most common site of involvement.
- acro-osteolysis (resorption of the distal phalanges)
- periarticular osteopenia
- joint space narrowing
- severe resorption of the first CMC joint with radial subluxation is a characteristic feature on hands radiographs
Soft tissue changes:
- subcutaneous and periarticular calcification
- atrophy especially at tips of fingers
- flexion contractures
Other less common documented musculoskeletal findings:
- rib resorption (bilateral superior rib notching, predominantly along posterior surface), mandibular angle resorption (+/- loss of lamina dura), radius and ulna resorption
- terminal phalangeal sclerosis
