Mandibular fracture in a Lhasa Apso with renal secondary hyperparathyroidism

A three-year-old Lhasa Apso was presented with a manibular fracture following a fi ght with another dog. The physical examination revealed generalised excessive mobility of the entire dentition. Radiographs revealed generalized mandibular demineralisation. Routine laboratory analyses revealed severe anaemia and azotaemia, compatible with chronic renal disease. The findings were considered consistent with renal secondary hyperparathyroidism resulting in bone demineralisation and minimal-trauma fracture.
