About Metabolic Bone Disease
Metabolic Bone Disease (MBD) is a common condition in captive reptiles and amphibians resulting from inadequate calcium metabolism. It encompasses nutritional secondary hyperparathyroidism, osteomalacia, and rickets. The condition leads to progressive weakening of bones due to calcium depletion, often caused by insufficient UVB exposure, dietary calcium deficiency, or improper calcium-to-phosphorus ratios.
Category: Metabolic/Nutritional
Severity: Moderate to Severe
Symptoms to Watch For in Your Tiger Salamander
- Soft, rubbery jaw
- Bowed or swollen limbs
- Tremors and muscle twitching
- Lethargy and weakness
- Difficulty walking or climbing
- Spinal deformities (kyphosis)
- Fractures from minimal trauma
- Inability to retract into shell (turtles)
Causes
Inadequate UVB lighting (prevents vitamin D3 synthesis), dietary calcium deficiency, excessive dietary phosphorus (inverted Ca:P ratio), insufficient vitamin D3 supplementation, and lack of access to natural sunlight. Commonly seen in insectivorous reptiles fed unsupplemented insects.
Diagnosis
Clinical signs and husbandry history. Radiographs showing decreased bone density, pathological fractures, and cortical thinning. Blood calcium levels (often normal due to parathyroid compensation). Ionized calcium and vitamin D3 levels provide more accurate assessment.
Treatment Options
Correct husbandry: proper UVB lighting (10-12% for desert species), calcium supplementation with vitamin D3, balanced diet with appropriate Ca:P ratio (2:1). Severe cases: injectable calcium gluconate, oral calcium, assisted feeding, splinting of fractures.
Prevention for Tiger Salamander
Proper UVB lighting appropriate to species. Gut-loading feeder insects with calcium. Dusting food with calcium powder. Providing cuttlebone or calcium blocks. Regular husbandry audits. Species-appropriate diet research.
Prognosis
Early/mild cases: good with husbandry correction. Moderate cases: may recover with permanent deformities. Severe cases with spinal involvement or organ damage: guarded to poor. Prevention is far more effective than treatment.
