This article presents the design and implementation of an automatic surgery module based on augmented reality (AR)- based 3D reconstruction. The system enables remote surgery by allowing surgeons to inspect reconstructed features and replicate surgical hand movements as if they were performing the surgery in close proximity.

Source: Kay Stewart, RVT, RLATG, CMAR; Valerie A. Schroeder, RVT, RLATG. University of Notre Dame, IN The Guide for the Care and Use of Laboratory Animals1 dictates that rodent survival surgery be performed aseptically. Aseptic technique utilizes specific practices that minimize the contamination of the surgical site, including patient preparation, surgeon preparation, sterilization of instruments and other supplies, and the use of a clean and controlled environment. Presurgical planning,...

The generation, purification and cell invasion of intracellular, cytoplasmic full length DISC1 protein aggresomes from cell cultures and of a labeled, multimeric recombinant DISC1 protein fragment in E. coli are described. Cell invasiveness is shown for recipient cells in cell culture and for neurons in vivo after stereotactical brain inoculation.

Stereotaxic (or stereotactic) surgery is a method used to manipulate the brain of living animals. This technique allows researchers to accurately target deep structures within the brain through the use of a stereotaxic atlas, which provides the 3D coordinates of each area with respect to anatomical landmarks on the skull. After the skull is exposed, anesthetized animals are mounted on a specialized instrument known as a stereotaxic frame, which enables the precise placement of experimental...

The monitoring of extracellular neurotransmitter levels in distinct brain regions of freely moving animals offers insights on the link between neurotransmitter release and behavior. In vivo microdialysis coupled with electrochemical detection provides excellent anatomical and chemical resolution; and information on how basal neurotransmission is altered by pharmacological or physiological manipulations.
FAQs
The prosthetic disc is designed to support load while permitting controlled motion between adjacent vertebrae. This approach connects implant function to vertebral biomechanics, because the replacement must accommodate forces at the spinal segment without eliminating its movement. Researchers therefore assess both mechanical support and the extent to which the treated level continues to function as a moving spinal connection.
Vertebral biomechanics describe how forces and movement are distributed through the spinal segment. In Disc Replacement Surgery, these principles help explain whether an artificial disc can carry load and allow controlled motion after damaged disc material is removed. Biomechanical analysis therefore provides a scientific basis for studying implant performance and the treated segment’s long-term function.
Candidacy depends on more than the presence of disc-related symptoms. The procedure is primarily considered for selected patients with symptomatic disc degeneration that has not improved with conservative care, while spinal anatomy and other clinical factors also affect suitability. These criteria connect biological tissue degeneration with the practical question of whether an implant can be appropriately positioned and used.
The operation proceeds through several linked stages at the affected spinal segment. Surgeons first access the region, then excise the degenerated disc material, and finally position a prosthetic disc. Each stage prepares the segment for the next: removal addresses the damaged tissue, while implant placement provides the intended load support and controlled movement.
This option may be considered when a patient has symptomatic disc degeneration that has not improved with conservative care. It is not presented as suitable for every person with disc degeneration, because candidacy also depends on spinal anatomy and other clinical factors. The decision therefore combines persistent symptoms, biological disc condition, and patient-specific assessment.
Research examines how well the prosthetic disc supports load, permits controlled motion, and contributes to long-term function at the treated spinal segment. Studies also connect outcomes with implant design, vertebral biomechanics, and the biology of tissue degeneration. These measures help evaluate whether the procedure achieves its intended functional goals beyond immediate removal of damaged disc material.
