Die Achillessehnenruptur ist beim Kleintier eine seltene Erkrankung mit einer guten Prognose. In der
Therapie stellt die Immobilisation und die anschliesende Mobilisation der Gliedmase den wichtigsten
Faktor dar, wobei in diesem Zusammenhang auch am meisten Komplikationen zu verzeichnen sind.
Um die 60 Publikationen befassen sich mit der atlantoaxialen Instabilitat und ihrer Therapie. Eine
generelle Empfehlung fur die ideale Behandlungsmethode kann daraus aber nicht abgeleitet werden. Es muss
fur jeden Patienten individuell entschieden werden, von welcher Technik er am meisten profitiert.
Die Wirbelsaulen von Hund und Mensch weisen sowohl anatomisch als auch funktionell einige
Gemeinsamkeiten, aber auch Unterschiede auf. Da der Hund oft als Modell fur Bandscheibenproblematiken in
der Humanmedizin herangezogen wird, lohnt es sich, diese Thematik genauer zu betrachten. Interessant ist
auch die Herangehensweise im Bereich der Therapie,...

CSF shunting and durotomy are both effective at controlling intracranial pressure and improving outcome. One could argue that the durotomy should result in free flow of CSF in order to be effective, but in practice, in patients with paraplegia and loss of deep pain perception that might benefit from such an intervention, the spinal cord frequently...
Removal of the compressive disc material is the main objective of surgical treatment of thoracolumbar disc herniation. The most common surgical techniques can be classified into three types: hemilaminectomy, partial corpectomy, and dorsal laminectomy. Combination of these techniques might also be possible in some instances and may also help to solv...
Corticosteroids have been the main pharmacologic agent utilized in the treatment of intervertebral disc disease (IVDD), including patients with pain only as well as those with neurologic deficits. Studies of nonsteroidal anti-inflammatory drugs (NSAIDs) in patients with intervertebral disc herniation focus primarily on inhibition of the hyperalgesi...

Intervertebral disc (IVD) degeneration and herniation are considered the main causes of acute and chronic low back pain in humans, with a lifetime prevalence of over 70% in the global population. Also, dogs commonly suffer from back pain caused by degenerated IVDs subsequently herniating; it is in fact the most common cause of neurological deficits...
Notwithstanding the decreased rate of recurrence after prophylactic fenestration, there are some factors that the veterinary surgeon has to consider when contemplating adding fenestration, as an adjunctive treatment of first-time intervertebral disc extrusion, of remote discs concomitant with decompression of a herniated disc. This chapter analyzes...
For the purposes of simplification, we can consider compressive spinal cord injury (SCI) to represent spinal cord deformation and shifting from its normal position within the vertebral canal. Contusive SCI, on the other hand, is the actual disruption of parenchyma (neuronal cell bodies, axons, glial cells, myelin, and microvasculature) within the s...
From a biomechanical viewpoint, the intervertebral disc (IVD) can be regarded as a water-filled cushion that mediates and transmits compressive forces between vertebral bodies and provides mobility as well as stability to the spinal segment. The IVD functions in relation to the ligamentous apparatus of the spine, which consists of the interspinal,...
