Disc wall structural abnormalities can act as initiation sites for herniation
Autor: Volker Rasche, Hans-Joachim Wilke, Kelly R. Wade, Nikolaus Berger-Roscher
Publikováno v: European Cells & Materials, Vol 40, Pp 227-238 (2020)
Both posture and loading rate are key factors in the herniation process and can determine the failure mechanism of the disc. The influence of disc structure on the herniation process has yet to be directly observed, thus the aim of this study was to

A biomechanical comparison of a cement-augmented odontoid screw with a posterior-instrumented fusion in geriatric patients with an odontoid fracture type IIb
Autor: Rolf Kalff, Nikolaus Berger-Roscher, Yasser Sakr, Falko Schwarz, Hans-Joachim Wilke, Christian Liebsch, Albrecht Waschke
Publikováno v: European spine journal : official publication of the European Spine Society, the European Spinal Deformity Society, and the European Section of the Cervical Spine Research Society. 30(6)
Purpose Possible surgical therapies for odontoid fracture type IIb include odontoid screw osteosynthesis (OG) with preservation of mobility or dorsal C1/2 fusion with restriction of cervical rotation. In order to reduce material loosening in odontoid

A new dynamic six degrees of freedom disc-loading simulator allows to provoke disc damage and herniation
Autor: Hans-Joachim Wilke, Annette Kienle, Sebastian Maile, Volker Rasche, Nikolaus Berger-Roscher
Publikováno v: European Spine Journal. 25:1363-1372
Purpose The cause of disc herniation is not well understood yet. It is assumed that heavy lifting and extreme postures can cause small injuries starting either in the inner anulus or from the outside close to the endplate. Such injuries are accumulat

Pedicle screw loosening: a clinically relevant complication?
Autor: Sandra Reitmaier, Annette Kienle, Hans-Joachim Wilke, David Volkheimer, Nikolaus Berger-Roscher, Fabio Galbusera
Publikováno v: European Spine Journal. 24:1005-1016
Literature studies showed a very wide range of pedicle screw loosening rates after thoracolumbar stabilization, ranging from less than 1 to 15 % in non-osteoporotic patients treated with rigid systems and even higher in osteoporotic subjects or patie

Finite element modeling has been widely used to simulate the mechanical behavior of the intervertebral disc. Previous models have been generally limited to the prediction of the disc behavior under simple loading conditions, thus neglecting its respo

Intervertebral disc lesions: visualisation with ultra-high field MRI at 11.7 T
Autor: Volker Rasche, Hans-Joachim Wilke, Nikolaus Berger-Roscher, Fabio Galbusera
Publikováno v: European spine journal : official publication of the European Spine Society, the European Spinal Deformity Society, and the European Section of the Cervical Spine Research Society. 24(11)
Tears and fissures in the intervertebral disc are probably influencing spinal stability. Discography investigations with the aim of fissure detection have been criticised and are discouraged. Therefore, alternative imaging methods, such as MRI, must

Increase or decrease in stability after nucleotomy? Conflicting in vitro and in vivo results in the sheep model
Autor: Anita Ignatius, David Volkheimer, Nikolaus Berger-Roscher, Hans-Joachim Wilke, Sandra Reitmaier
Publikováno v: Journal of the Royal Society, Interface. 11(100)
Nucleotomy is a common surgical procedure to treat disc herniations. The potential occurrence of segmental instability after surgery, however, is suspected to necessitate re-operation and fusion. Although in vitro studies support the theory of destab
