“…We made our comparisons with studies in domestic cats (5,8) and dogs (9,10) since the applied methods were the same. Data on pelvimetry remain scarce even in domestic animals and especially in males, because studies mostly focus on the contribution of female pelvic size to rearing performance (9,11,12); however, depending on their pelvic shape, animal species can be classified as dolicopelvic, platypelvic or mesatipelvic.…”

“…Sexual dimorphism of the pelvic bone has been described in humans (20), non-human primates (21), Retriever dogs (22) and domestic cats (8), whereas it is not present in the German shepherd dog (10). This dimorphism can be characterized by a difference in pelvic size and/or pelvic conformation, and if these differences are marked, they can contribute to the sex determination of an individual (20,22).…”

“…In addition, we calculated two ratios between the height and width of the pelvis: vertical diameter/acetabula (VD/AC) and sagittal diameter/transversal diameter (SGD/TD). Furthermore, we estimated the pelvic inlet area (PIA) and pelvic outlet area (POA) as follows: PIA = (CV/2 + TD/2) 2 × π, and POA = (VD/2 + AC/2) 2 × π (10), with CV corresponding to the distance between the promontory and cranial pubic symphysis (or conjugata vera, Fig 2A). The pelvic inlet area (PIA) is a planar surface which corresponds to the boundary between the pelvic and the abdominal cavity.…”

“…It can be done by palpation or on x-rays. Radiographic pelvimetry is often used to calculate the pelvic size in humans, and has also been employed in domestic animals such as cats (5,8), dogs (9,10), cattle (11), sheep (12) and Indian buffaloes (13).…”

16The observation of severe pelvic malformations in Eurasian lynx (Lynx lynx) from a 17 population reintroduced to Switzerland raised the question as to whether inbreeding may 18 contribute to the development of congenital pelvic malformations. We aimed at providing 19 baseline data on the pelvic morphology of Eurasian lynx from the reintroduced populations in 20 Switzerland, at assessing potential differences in pelvic conformation between the two main 21 Swiss populations, among age classes and between sexes, and at detecting pelvic anomalies. 22 We performed measurements of 10 pelvic parameters on the radiographs of 57 lynx of both 23 sexes and different ages taken from 1997-2015. We calculated two ratios (vertical 24 diameter/acetabula; sagittal diameter/transversal diameter) and two areas (pelvic outlet and 25 inlet) to describe the shape of the pelvis. Our results showed that the Eurasian lynx is a 26 mesatipelvic species, with a pelvis length corresponding to approximatively 20% of the body 27 length. We found no statistically significant differences between the two examined 28 populations but observed growth-related pelvis size differences among age groups. Sexual 29 dimorphism was obvious in the adult age group only: two parameters reflecting pelvic width 30 were larger in females, likely to meet the physiological requirements of parturition. By 31 contrast, pelvis length, conjugata vera, diagonal conjugata, vertical diameter and sagittal 32 diameter were larger in males, in agreement with their larger body size. Accordingly, the ratio 33 between the sagittal and transversal diameters was significantly larger in males, i.e. adult 34 males have a different pelvic shape than adult females. Furthermore, pelvimetry highlighted 35 one adult individual with values outside the calculated reference range, suggesting a possible 36 congenital or developmental pathological morphology of the internal pelvis. Our work 37 generated baseline data of the pelvic morphology including growth and sexual dimorphism of 38 the Eurasian lynx. These data could also be useful for estimating age and sex in skeletal 39 remains. 42 end of the 19th century. Following habitat improvementy and prey recovery, lynx 43 reintroductions took place in the 1970s, with lynx imported from the Capathian Mountains in 44 Slovakia. In Switzerland, two small distinct lynx populations resulted from these releases: one 45 in the Swiss Alps extending slightly into France and Italy, and another one in the Jura 46 Mountains at the border with France, both estimated at approximatively 100-150 independent 47 lynx, with a total of approximately 130-140 lynx in the Swiss territory (1). However, these 48 populations are now characterized by a low genetic variability and a high inbreeding 49 coefficient (2). 50 A lynx health monitoring program has been conducted at the Centre for Fish and 51 Wildlife Health (FIWI) in Switzerland for several decades, including necropsies of carcasses, 52 clinical examinations of live lynx and systematic sampling.

“…In the light of data on the tomographic appearance of the hip joint in both normal and dysplastic hip 21 , dogs with hip dysplasia in this study had been evaluated by computed tomography as well as in the early and late post-operative periods. When basing the evaluation on length measurements, some changes were seen also in the unoperated hip joints.…”

Triple pelvic osteotomy (TPO) is one of the main surgical procedures to prevent or modify the progress of degenerative joint disease (DJD) related with hip dysplasia in young dogs. The aim of this study was to evaluate the effects of TPO in dogs. In this study, TPO were performed in 7 dysplastic cross-breed dogs in different gender (6 female and 1 male) and body weight (13.42±2.29 kg). In all cases, 20 degrees canine TPO plates were used. Before the operation, all cases were examined clinical, radiological and by computed tomographic. Postoperative 2 nd and 6 th weeks dogs were examined clinical, radiological and by computed tomographic and after 6 month both clinical and radiological examinations were performed. The joint laxity decreased 2 weeks after the operation. Dogs could walk on the treated leg after 2 weeks. The joint laxity decreased 2 weeks after the operation. Postoperatively dogs could walked on the treated leg after 2 weeks. The postoperatively measured Norberg angles (P<0.01) and acetabular anteversion angle (P<0.05) were significantly higher and distance between caput femoris and acetabulum was significantly lower (P<0.05) than preoperatively measurements. So, contact surface between the femoral head and the acetabulum had increased and the subluxation had disappeared. In radiographs obtained 6 months later, degenerative joint disease was not encountered. It was decided that canine hip dysplasia, could be treated successfully in young dogs via TPO, carried out before degenerative changes begin within the hip joints. Keywords: Hip dysplasia, Triple pelvic osteotomy, Radiological, Computed tomography, Dog Köpeklerde Kalça Displazisi'nin Sağaltımında Triple Pelvik Osteotomi Etkilerinin Klinik, Radyolojik ve Bilgisayarlı Tomografi ile Değerlendirilmesi ÖzetTriple pelvik osteotomi (TPO) genç köpeklerde kalça displazi ile ilgili dejeneratif eklem hastalığı (DJD)'nın ilerlemesini önlemek ve değiştirmek için uygulanan cerrahi bir işlemdir. Bu çalışmanın amacı, köpeklerde TPO'nun etkilerini araştırmaktır. Bu çalışmada, farklı cinsiyet (6 dişi, 1 erkek) ve vücut ağırlığındaki (13.42±2.29 kg) displazik 7 köpekte TPO yapıldı. Bütün olgularda, 20º canin TPO plağı kullanıldı. Operasyon öncesi tüm olguların klinik, radyolojik ve bilgisayarlı tomografi ile muayeneleri yapıldı. Köpekler operasyon sonrası 2. ve 6. haftalarda klinik, radyolojik, bilgisayarlı tomografik muayene ve 6 ay sonra hem klinik hem de radyolojik muayeneleri yapılarak takip edildi. Operasyondan 2 hafta sonra eklem gevşekliği azaldı. Köpekler operasyon sonrası 2 haftada tedavi edilen bacakları üzerinde yürüyebiliyorlardı. Postoperatif ölçülen Norberg açıları (P<0.01) ve asetabular antreversiyon açısı (P<0.05) preoperatif değere göre yüksekti ve kaput femoris ve asetabulum arasındaki mesafe belirgin olarak düşük bulundu. Bu nedenle, asetabulum ve kaput femoris arasındaki temas yüzeyi artarak, subluksasyon kayboldu. Altı ay sonra elde edilen radyografilerde, dejeneratif eklem hastalığına rastlanmadı. Kalça displazili genç köpeklerde kalça eklemi...

ZusammenfassungIm Rahmen der Trächtigkeitsüberwachung des Hundes spielen die bildgebenden Verfahren eine entscheidende Rolle. Die Sonografie hat sich zu der Modalität der Wahl bei der Trächtigkeitsdiagnose etabliert und bietet die Möglichkeit, eine Trächtigkeit bereits ab dem 17.–20. Tag nach dem LH-Peak nachzuweisen. Weiterhin ermöglicht sie eine Beurteilung der fetalen Vitalität und Entwicklung, die Darstellung von fetalen Missbildungen und die frühzeitige Erkennung von fetalem Stress. Hierbei kann auch die Doppler-Sonografie unterstützend eingesetzt werden. Die Bestimmung des Wurfzeitpunktes kann über die Beurteilung des fetalen Entwicklungsstandes und über Messungen der fetalen und extrafetalen Strukturen erfolgen. Die Röntgendiagnostik ermöglicht einen Trächtigkeitsnachweis ca. ab dem 43. Tag nach dem LH-Peak und bietet eine Beurteilung der Wurfgröße und der Größe der einzelnen Feten. Bei Geburtsstörungen und Dystokiepatienten liefern beide Verfahren komplementär schnelle Aussagen zu verschiedenen Fragestellungen, die die Entscheidung für einen operativen Eingriff unterstützen und das Management von Hündin und Welpen bestimmen.
