*[Paraphrased derived summary — non-Open-Access source.]* Secondary nutritional hyperparathyroidism is the most common bone disease in reptile practice; it comes from poor diet (low calcium:phosphorus, vitamin D3 deficiency) or poor husbandry (no UVB, too little heat). *[Paraphrased derived summary — non-Open-Access source.]* In green iguanas it shows as swollen, fibrous long bones and upper jaw — a disease of mismanagement. *[Paraphrased derived summary — non-Open-Access source.]* An iguanid-lizard radiograph can show widespread bone loss with periosteal new bone on long bones and jaw, consistent with secondary nutritional hyperparathyroidism.
