Causes
A lack of calcium in the diet, absence of UVB light (needed to produce vitamin D3 and absorb calcium), an inadequate terrarium temperature, or excess phosphorus. It is a husbandry problem.
Diagnosis
Examination plus X-rays that reveal the low bone density and the deformities.
Treatment
Correct the husbandry URGENTLY: adequate UVB light, correct temperature, calcium supplements and a suitable diet. Advanced cases require intensive veterinary treatment. Deformities that have already formed cannot be reversed.
Prevention
Correct UVB lighting, replaced periodically, a temperature gradient suited to the species, a diet with the correct calcium-to-phosphorus ratio, and supplementation according to the species.
