Vorkommen von lumbosakralen Übergangswirbeln bei Alpenländischen Dachsbracken, Brandlbracken, Bayrischen Gebirgsschweißhunden, Hannoverschen Schweißhunden und Steirischen Rauhaarbracken bei der routinemäßigen HD-Untersuchung zur Zuchtzulassung in den Jahren 1986 bis 2011.
Presence of Lumbosacral Transitional Vertebrae in the Alpine Dachsbracke, the Austrian Black and Tan Hound, the Bavarian Mountain Scenthound, the Hanoverian Scenthound and the Coarse-haired Styrian Hound during Hip dysplasia Screening in the Years from 1986 to 2011
Diplomarbeit, Vet. Med. Univ. Wien, pp. 75.
The aim of this study was to detect the presence of lumbosacral transitional vertebrae (LTV) in the Alpine Dachsbracke (AD), the Austrian Black and Tan Hound (BB), the Bavarian Mountain Scenthound (BG), the Hanoverian Scenthound (HS) and the Coarse-haired Styrian Hound (SR) and to evaluate a possible connection between LTV and canine hip dysplasia (CHD).
616 X-rays have been evaluated, archived by the division for diagnostic imaging of the University for Veterinary Medicine in Vienna.
The lumbosacral transitions were divided into four types: type 0 representing the normal lumbosacral transition; type 1 which originates from an incomplete connection of the first sacral element to the rest of the sacrum with an isolated spinous process of the first sacral element; type 2, a symmetric LTV, which is shorter and located more caudally compared with a normal lumbar vertebra, and finally type 3, which is an asymmetric LTV with a partial connection to the sacroiliac joint. (FLÜCKIGER et al., 2009)
115 dogs had a LTV type 1, 22 dogs a LTV type 2 and 6 dogs a LTV type 3, but a connection between a LTV and CHD could not be proved statistically as published in former papers (LARSEN, 1977; WINKLER, 1985; JULIER-FRANZ, 2006).
The calculated incidence was 27,3% and therefore inbetween the results of former publications 2,13% (LARSEN, 1977), 40,4% (LAPPALAINEN et al., 2012). Nevertheless the incidences varied within the breeds from 11,8% (AD) to 37,3% (HS).
Interesting results manifested the evaluation of hip dysplasia degrees. AD and BG breed with HD A, B, C and D. This is reflected by the frequency of HD with 30% of HD A and HD C. The frequency of HD in BB and HS shows a contrary outcome. These dogs are only allowed to breed with HD A and B and the HS is also allowed to breed with HD C so that more than 50% of these dogs were reported with CHD A and less than 20% were reported with CHD C.
