Metabolic Bone Disease
Nutritional secondary hyperparathyroidism
Također poznato kao: Nutritional Secondary Hyperparathyroidism, NSHP, Fibrous Osteodystrophy, Osteomalacia, Rickets
Ukratko
Metabolic Bone Disease (MBD), or nutritional secondary hyperparathyroidism, is a common and serious condition in captive reptiles and turtles. Caused by a lack of dietary calcium, improper calcium-to-phosphorus ratios, or insufficient UVB light, it leads to weak, deformed bones and muscle tremors. Learn how to recognize the signs, how veterinarians diagnose and treat it, and how proper husbandry can prevent this debilitating disease.
TL;DR. Sprečivo stanje gmazova i kornjača zbog manjka kalcija ili UVB: meke kosti, deformacije i tremor.
UVB svjetlo je ključno za sintezu vitamina D3 i apsorpciju kalcija.
Što je to?
Metabolic bone disease in captive reptiles/turtles is usually nutritional secondary hyperparathyroidism: insufficient calcium or UVB leads to soft bones, fibrous reinforcement of limbs/jaws, and muscle tremors.
Uzroci i čimbenici rizika
Husbandry errors: inadequate UVB (290-315 nm), low dietary calcium, poor Ca:P ratio (aim near 2:1), cold enclosures. Fast-growing species are highest risk.
Znakovi
- Rubber jaw; soft/warped shell in chelonians (cardinal)
- Swollen firm limbs, pathological fractures, lethargy, anorexia, tremors (common)
- Paresis/paralysis from spinal deformity (occasional)
Skrácena čeljust i otečeni udovi klasični su kasni znakovi.
Dijagnostika
Husbandry review. Radiographs (gold): demineralized ghost bones, hidden fractures. Ionized calcium; biochemistry for kidney and phosphorus.
RTG pokazuje demineralizirane kosti i skrivene prijelome.
Liječenje
Oral or injectable calcium salts; phosphate binders if phosphorus high; cautious calcitriol after calcium stabilizes. Fix UVB, heat gradient, diet.
Prognoza
Excellent if early before severe deformity. Permanent shape changes may remain. Poor with paralysis or severe kidney disease.
Prevencija
Linear UVB (replace every 6-12 months), calcium (± D3 indoors), gut-load insects, Ca-rich greens, correct thermal gradient.
Kada zvati veterinara
Emergency: continuous tremors/seizures, inability to lift body, soft jaw/shell, visible fractures, extreme lethargy or prolonged anorexia.
