Wedging of apical spinal segments was measured during creation and correction of an experimental scoliosis in a goat model. ⋯ This study demonstrates the ability to create wedge deformities at the apex of an experimental scoliosis in a large animal model and to control the progression of these deformities using anterior thoracic staples.

Randomized Controlled Trial Multicenter Study Comparative Study
Revisability of the CHARITE artificial disc replacement: analysis of 688 patients enrolled in the U.S. IDE study of the CHARITE Artificial Disc.
A prospective, randomized, multicenter, FDA-regulated Investigational Device Exemption clinical trial. ⋯ Lumbar TDR with the CHARITE Artificial Disc did not preclude any further procedures at the index level during primary insertion, with nearly one third being revisable to a new motion-preserving prosthesis and just over two thirds being successfully converted to ALIF and/ or posterior pedicle screw arthrodesis, the original alternative procedure.

Comparative Study
Open reduction of irreducible atlantoaxial dislocation by transoral anterior atlantoaxial release and posterior internal fixation.
A retrospective study of surgical outcome of 33 patients with irreducible atlantoaxial dislocation (IAAD). ⋯ This series has demonstrated the safety and efficacy of the transoral anterior atlantoaxial release in the reduction of IAAD. Most of the so-called irreducible/fixed AAD could become reducible after anterior release without odontoid resection. The posterior short-segment atlantoaxial or occipitocervical fixation, especially the plate screw instrumentation, could achieve further reduction and provide immediate stabilization. One-stage anterior release and posterior instrumentation and fusion are a safe and reliable operation in experienced hands.

: Literature review. ⋯ : While many advances in the basic science of spinal cord injury provide optimism for future treatments, clinical science lags. At present, there are no pharmacologic strategies of proven benefit. Although steroids continue to be given to patients with spinal cord injury in many institutions, evidence of deleterious effects continues to accumulate. Current standard of care management includes support of arterial oxygenation and spinal cord perfusion pressure.

Literature review and expert opinion. ⋯ The application of MIS techniques to spinal trauma is theoretically sound. However, the indications and technology are currently in evolution. Although very limited information is available, the results of current MIS techniques for the management of TL trauma are encouraging.
