Nursemaid elbow, x-ray
NE (or babysitter’s elbow, pulled elbow, radial head subluxation) occurs when the radial head slips under the annular ligament and is displaced downward.
This ligament is weaker in children and consequently increases the risk of radial head subluxation, as seen in the image.
NE is a common childhood injury that occurs when a child’s arm is pulled up and out.
Classic history is a child with no history of trauma who suddenly refuses to use one arm, though bilateral cases can occur.
The joint can typically be easily reduced and should result in an immediate return to normal function.
Calcinosis cutis, X-ray
Calcinosis cutis refers to calcium deposition in the skin and soft tissues. It presents with subcutaneous white or pink nodules, often in the upper extremities. It is the first component of CREST syndrome, which includes
- Calcinosis cutis
- Raynauds phenomenon
- Esophageal dysmotility
- Sclerodactyly
- Telangiectasias.
CREST syndrome is a type of systemic scleroderma where anti-centromere antibodiesresult in systemic inflammatory autoimmune connective tissue pathology.
