Ist die plastische Deformation der proximalen Tibia ein Faktor bei der Pathogenese des vorderen Kreuzbandrisses des Hundes?


Ettlin, Chloé. Ist die plastische Deformation der proximalen Tibia ein Faktor bei der Pathogenese des vorderen Kreuzbandrisses des Hundes? 2017, University of Zurich, Vetsuisse Faculty.

Abstract

The rupture of the cranial cruciate ligament is ↲ the most common cause of hind limb lameness in dogs. The m↲ ultifactorial etiopathogenesis is discussed in this manusc↲ ript. The causes include immunological and inflammatory fa↲ ctors, genetic components and the plastic deformation of t↲ he tibia – the latter resulting in altered biomechanics of↲ the stifle. Many therapeutic options have been developed ↲ depending on the suspected cause. Tibia osteotomies repres↲ ent the newest therapeutic approach to restore the physiol↲ ogical biomechanics of the stifle. The best known techniqu↲ es are certainly the tibial tuberosity advancement (TTA) a↲ nd the tibial plateau levelling osteotomy (TPLO). While th↲ e TTA results in a broader tibia, the TPLO results in a re↲ duced tibia plateau angle. In our study we examined the pr↲ oximal tibia of 100 dogs with intact cranial cruciate liga↲ ment (group I) and 100 dogs with ruptured cranial cruciate↲ ligament (group R). Tibia width and the tibial plateau an↲ gle (+/- standard deviation) were measured. The tibia widt↲ h was 39.43 +/- 9.13mm in group I, and 40.83 +/- 8.98mm in↲ group R. The tibia plateau angle of dogs in group I was 2↲ 7.20 +/- 3.39°, in group R 28.58 +/- 3.76° respectivley. L↲ ogisitc regresssion analysis indicated that the odds for a↲ rupture of the cruciate ligament increases by 34% per mil↲ limeter decrease of the tibia width and about 15% per degr↲ ee increase of the tibia plateau angle. Therefore our stud↲ y confirms that the odds for a rupture increases with a sm↲ all tibia width and a steep tibia plateau angle. This expl↲ ains the good outcome of both surgical techniques. Inadequ↲ ate breeding is the suspected cause for the plastic deform↲ ation of the proximal tibia.
