Pelvimetry in bitches N.R.D. (no race defined)

Abstract

Pelviology means the study of the pelvis, a structure formed by bones, ligaments and muscles. One of the subjects of pelviology corresponds to pelvimetry, which deals with the measurement of pelvic measurements, and which has a close relationship with reproduction. This study aims to verify the correlation between some body parameters and pelvic measurements. We used 50 N.R.D. female canine cadavers, varying in age and size, from euthanasia or natural death from the HOVET of UNIDESC and Veterinary Clinics of the cities of Valparaíso, Goiás-GO and Santa Maria-FD. Initially the body length, body height, thoracic perimeter, and body weight parameters were measured. Then, the bony pelvis was removed from the cadaver, sectioning the spine at the level between the lumbar vertebrae 5 (L5) and 6 (L6) and the femur in its middle third. Immediately after this procedure, the excess soft tissue was removed. In pelvimetry the following diameters were measured: thigh bone; transverse; acetabular; lateral ischiatic; true conjugate and vertical. The following mean values and standard deviation were obtained: 1) Body parameters: body weight (Kg) -8.40 ± 5.86; height (cm) -35.50 ± 11.76; body length (cm) -48.60 ± 13.48; and thoracic perimeter (cm) -43.80 ± 14.24; and 2) Pelvic diameters (cm): thigh bone -3.313 ± 0.830; transversal -3.864 ± 0.900; acetabular -4.326 ± 1.140; lateral ischiatic -7.171 ± 2.140; true conjugate -4.720 ± 1.270; and vertical -4.697 ± 1.270. Finally, it was verified that there is a significant positive correlation between body parameters and pelvic diameters.
