Case Discussion

Radiograph - Irregularity of cortex and loss of bone is seen at outer end of clavicle favour ostelysis. Acromian cortex is normal.

US - Findings of radiograph are confirmed. There is distension of joint space with synovial thickening.

In view of history of trauma and radiograph - ultrasound images, post traumatic osteolysis of outer end of clavicle is most likely.

Other differentials which are ruled out includes -

  1. Rhematoid arthritis
  2. Hyperparathyroidism
  3. Multiple myeloma
  4. Metastasis
  5. Cleidocranial dysplasia
  6. Pyknodysostosis.
