Long-term anchorage of foreign material in vital bone has proven to be the main problem in endoprosthetics. In the authors opinion, modelling of an individual anatomic anchorange component is, at present, the best way to transmit stresses harmoniously in order to utilize functional adaptation of bone and to attain long-term function. The production of a true-to-scale joint model is possible with computer-assisted-tomography. This model of a joint surface or bone canal can be used to construct an individual endoprosthesis prior to surgery. Our procedure of manifactoring a hip stem and a knee-surface-prosthesis is described.

Surmounting the ceiling effect of motor expertise by novel sensory experience with a hand exoskeleton.
Sci Robot
January 2025
Sony Computer Science Laboratories Inc. (Sony CSL), Tokyo, Japan.
For trained individuals such as athletes and musicians, learning often plateaus after extensive training, known as the "ceiling effect." One bottleneck to overcome it is having no prior physical experience with the skill to be learned. Here, we challenge this issue by exposing expert pianists to fast and complex finger movements that cannot be performed voluntarily, using a hand exoskeleton robot that can move individual fingers quickly and independently.

J Neurol
January 2025
Department of Neurology, Clinic of Optic Neuritis and Danish Multiple Sclerosis Center, Rigshospitalet-Glostrup, Valdemar Hansens Vej 13, 2600, Glostrup, Denmark.
Background: Although optic neuritis (ON) is common in multiple sclerosis (MS), lesions of the optic nerve are not included as an anatomical substrate for dissemination in space and time (DIS and DIT).
Objective: To assess the increase in sensitivity of including MRI lesions of the optic nerve for the diagnosis of MS in patients with ON.
Methods: We included patients consecutively referred with first time, monosymptomatic ON, with no known cause of the ON, who underwent orbital MRI including fat suppressed T2 and T1-sequences with and without gadolinium contrast.
Indocyanine green dyed gauze-guided minimum invasive surgery for anatomical landmarks and preventing gauze remnants: a pilot study.
Langenbecks Arch Surg
January 2025
Department of Chemical Science & Engineering, School of Materials and Chemical Technology, Institute of Science Tokyo, 2-12-1 Ookayama, Meguro-ku, Tokyo, 152-8552, Japan.
Purpose: We aimed to develop a novel fluorescent surgical gauze dyed with indocyanine green (ICG) to guide surgeons to the target anatomical destination during surgery for real-time navigation and to prevent gauze remnants after surgery.
Methods: Surgical gauze was dyed with an aqueous solution of ICG (5.0 × 10 mol L for Steraze, 1.
Anatomy-driven segmentation of parafoveal optical coherence tomography (OCT) measures may improve associations with clinical outcomes in multiple sclerosis.
J Neurol
January 2025
Jacobs Comprehensive MS Treatment and Research Center, Department of Neurology, Jacobs School of Medicine and Biomedical Sciences, University at Buffalo, State University of New York, Buffalo, NY, USA.
Background: Previous investigations on optical coherence tomography (OCT) in multiple sclerosis (MS) focused on generalizable macular and peri-papillary regions without considering the anatomic variations of the retinal layer thickness.
Objective: This study aimed to assess the utility of parafoveal retinal layer thickness measured by OCT, underscoring its relationships with clinical outcomes in MS.
Methods: In this cross-sectional study, 214 people with MS (pwMS) and 57 age- and sex-matched healthy controls (HCs) were enrolled.
Vascularized Periosteal Grafts for Bone Union in Children: A Systematic Review.
Microsurgery
January 2025
Pediatric Hand Surgery and Microsurgery Unit, Instituto de Investigación Sanitaria HM Hospitales, Barcelona, Spain.
Background: The periosteum is the main organ responsible for bone regeneration. Vascularized Periosteal Grafts (VPG) have demonstrated exceptional efficacy and speed in facilitating bone union among children with challenging bone healing conditions. Despite their promising results, the overall impact of these interventions has yet to be comprehensively evaluated through systematic review.
