Evaluation of Densitometric and Geometric Parameters of Tibiotarsal Bones in Turkeys

The aim of the study was to analyse densitometric and geometric parameters of healthy and deformed tibiotarsal bones of male turkeys of heavy type with the use of computed tomography. The influence of a bone type (healthy or deformed) and the area of the measurements (the proximal metaphysis and middle of the diaphysis) on these parameters were studied. It was found that the diaphysis of the deformed tibiotarsal bones (45 g) had higher values of the studied parameters than healthy bones (36 g) and they were as follows: BMC - 60.04 mg/mm, vBMD - 549.11 mg/cm³, TRAB_A - 48.34 mm², CRT_A - 55.57 mm², PERI_C - 37.55 mm, ENDO_C - 25.42 mm, SSI - 151.19 mm³. The studied parameters were significantly lower in the proximal metaphyses of the deformed tibial bones and amounted to: BMC - 29.48 mg/mm, TRAB_A - 42.22 mm², CRT_A - 21.44 mm², PERI_C - 34.64 mm, ENDO_C - 28.06 mm, SSI - 44.87 mm³. On the basis of the conducted research, it was found that significant differences in the densitometric and geometric parameters between the proximal metaphysis and the middle of the diaphysis of the deformed bones may result in deformities and fractures of tibiotarsal bones.
