Abstract
A five-month old tiger (Panthera tigris tigris) presented
for an acute-onset pelvic limb lameness workup. The cub
had been fed a meat-only diet. Radiology revealed
severe generalised osteopenia, pathological fractures of
the pelvis and proximal right femur. The history, clinical
presentation and pathognomonic radiographic findings
were consistent with nutritional secondary
hyperparathyroidism. The cub was initially treated
conservatively by dietary management (whole chicken
supplemented with calcium-multivitamin powder).
Fourteen day follow-up radiographs revealed increased
bone density, healing pelvic fractures and callus
formation around the displaced femoral fracture
fragments. Despite the osteopenia, the femoral cortices
were considered dense enough to allow internal fixation
using a locking plate–rod combination. Fracture
reduction was complicated by extensive callus formation
and muscle atrophy. Follow-up radiography on day 63
revealed excellent secondary bone healing and improved
bone density. The cub was discharged into the owner’s
care and has reportedly made a full recovery.
