Presentation
Chronic shifting Lameness. Pain on left hip extension.
Patient Data
Left Humerus and proximal Antebrachium: The medulla of the left humeral diaphysis shows a mildly increased opacity compared to the right medulla. There is marked increase in medullary opacity in the mid and distal humeral diaphysis.
Right humerus: The soft tissues and osseous structures are normal.
Pelvis and proximal pelvic limbs: The diaphysis of the left femur shows a marked sclerosis, with a sharp transition to normal medulla on the lateral projection.
Impression: Panosteitis.
Case Discussion
Radiographic findlings are consistent with panosteitis affecting the left humerus, radius und femur. Panosteitis is a condition of young dogs characterized by shifting lameness if multiple limbs are affected. The medullary cavity becomes sclerotic and opaque, which is pathognomonic for the disease.
