Background: For about 20 years we have been observing the development of three-dimensional (3D) printing. The aim of this study was to systematize the current knowledge on the use of 3D printing technology in neurosurgery and to aetmpt an outline the future paths of its development. Material and methods: The analysis was based on English-language literature from 2017-2021 indexed in the Mendeley and Scopus databases. Results: The application of 3D printing in neurosurgery concerns: 1) teaching students, 2) training of residents neurosurgeons, 3) individualized surgery planning, 4) dedicated cranial and spinal implants, 5) the future of 3D printing in neurosurgical implantology. There were 5 main neurosurgery subtopics in which 3D printing was used: “vascular neurosurgery” (31%), “skull, cranial neurosurgery” (22.4%), “neuro-oncology” (19.3%), “spine” (14.3%) and “others” (13%). The number of published articles has been steadily increasing by 11-33% annually. Conclusion: 3D printing has an enormous potential for clinical use and in the we will continue to observe its dynamic development. In neurosurgery 3D prints are currently most commonly used for didactic purposes as detailed anatomical models, for training residents and young surgeons and by specialists for the simulation of complex or innovative surgeries. The future of the use of additive 3D printing in neurosurgery lies in the biological 3D printing, the creation of artifcial organs and the development of biological implants in tissue engineering.

Background: The coronavirus pandemic has strongly affected health-care systems around the world, testing their patients’ care capacities. Admission restrictions, patients’ fear of hospitalization or other uncomprehended constraints has affected admissions to neurosurgery department. Material and methods: The clinical data of admissions from March 1st to July 24th 2020, as well as data of the control group in relevant periods of time in 2019 was collected from the local hospital database and compared. Results: The total number of procedures performed between March and July 2020 is 1545, compared to the corresponding period of the previous year it was the number of 2062, indicating a decrease by about 25%. Both head and aneurysm procedures decreased over the entire analyzed period. The number of procedures classified as "other" was higher in each of the three stages. Between March 1st and April 30th (Phase 1) mainly younger male patients were admitted. Conclusions: We demonstrated the impact of the COVID-19 pandemic on the work organization of our Neurosurgery Department. We report that after the introduction of appropriate solutions, it is possible to provide care to neurosurgical patients while ensuring the safety of patients and Staff during the pandemic.

Introduction: Malignant gliomas (HGG) are the most common primary malignant brain tumors arising from glial cells. From among HGG, glioblastoma is the most common and the most malignant histological subtype, with only a 27% 2-year survival rate. Current standard medical treatment of malignant gliomas is still not satisfactory and may need some development and modification. We presented and discussed the achievements of the Department of Neurosurgery at Brodno Masovian Hospital in the treatment of malignant gliomas. Material and methods: We step by step presented and discussed the policy in the treatment of malignant gliomas. We showed all steps starting from the preparation of surgery (e.g. neuroimaging) and finishing on the presentation of the development of perioperative management – from intraoperative electrical stimulation mapping and monitoring which is nowadays already standard method to convection-enhanced delivery (CED) and gamma knife (GK) which are new and promising methods in the treatment of glioblastoma. Results: All surgical methods described in this manuscript were introduced to achieve a maximal and safe resection of a malignant glioma. CED and GK are the last-resort methods for patients with recurrent HGG. Discussion: Department of Neurosurgery at Brodno Masovian Hospital deals with all types of brain tumors, including all types of high-grade gliomas. As the first Department in Europe with close cooperation with the Department of Neurosurgery in San Francisco, we have started local infusions of drugs directly to the tumor in the real time of magnetic field, and we think that this technology may change all approaches to the treatment of high-grade gliomas.

Dotrzonowe iniekcje cementu akrylowego są nowoczesną metodą leczenia kompresyjnych złamań trzonów kręgowych w leczeniu paliatywnym przerzutów nowotworowych, w przebiegu osteoporozy, a także naczyniaków trzonów kręgowych. Metoda polega na wstrzyknięciu cementu (polimethylmethacrylate - PMMA) do trzonu kręgu, dzięki czemu uzyskuje się wypełnienie ubytków struktury kostnej. Efektem jest zmniejszenie dolegliwości bólowych oraz wzmocnienie i stabilizacja złamanego kompresyjnie trzonu. Przekłada się to na stabilność kręgosłupa i umożliwia szybkie wprowadzenie wczesnego postępowania fizjoterapeutycznego oraz indywidualnej aktywności fizycznej w procesie rehabilitacji. Celem pracy jest przedstawienie zalet, podstaw teoretycznych i praktycznych komplekso-wego postępowania terapeutycznego w leczeniu paliatywnym przerzutów nowotworowych do trzonów kręgowych i odbarczeniem elementów nerwowych metodą wertebroplastyki, z uwzględnieniem fizjoterapii okołooperacyjnej w materiale własnym. Od 2004 roku do kwietnia 2007 w 4WSKzP wykonano 78 zabiegów dotrzonowych iniekcji cementu, w tym u 56 pacjentów z przerzutami, 12 z powodu złamań osteoporotycznych i u 10 z naczyniakami trzonów. U 35 osób z przerzutami do trzonów kręgów zabieg wykonano podczas tzw. operacji otwartych. Pozostałe 43 osoby poddano przezskórnej wertebroplastyce (PWP). Przedstawione kompleksowe postępowanie terapeutyczne w wybranych schorzeniach kręgosłupa oraz stosowana fizjoterapia okołooperacyjna wydają się spełniać współczesne poglądy na ich leczenie. Stanowią alternatywę dla tradycyjnych metod wymagających często długotrwałego unieruchomienia wobec skutków hipokinezji. Obecny stan wiedzy oraz własne doświadczenia autorów wskazują na zasadność przyjętego modelu postępowania.

Polimethyl methacrylate (PMMA) intravertebral injections are a modern method in the treatment of vertebral compression fractures in palliative treatment of cancer metastases, osteoporosis, as well as of vertebral body haemanginoma. The method consists in injecting cement into the vertebral body, and thus filling bone structure losses. It results in reduced pain, strengthening and stabilization of the vertebral body in compression fractures. It translates into stability of the spine which in turn enables fast introduction of early physiotherapy and individually adjusted physical activity in the process of rehabilitation. The aim of the paper is to present advantages, practical and theoretical basis of the comprehensive therapeutic procedure in palliative treatment of vertebral compression fractures with operative decompression of the nervous elements in the vertebral canal by means of vertebroplasty, taking into consideration perioperative physiotherapy in the authors' own material. From 2004 to April 2007 in 4WSKzP [4th Military University Hospital with Polyclinic] 78 PMMA intravertebral injection procedures were performed, including 56 patients with metastases, 12 due to fractures caused by osteoporosis and in 10 patients with vertebral body haemanginoma. In 35 patients with metastases to the vertebral bodies, the procedure was performed during so-called open operations. The other 43 patients underwent percutaneous vertebroplasty. The comprehensive therapeutic procedure presented in this paper in selected spinal conditions as well as the applied perioperative physiotherapy seem to conform to contemporary views on the treatment of such conditions. It is an alternative for traditional methods frequently requiring long-term immobilization connected with the effects of hypokinesis. The present knowledge as well as the authors' own experiences confirm justifiability of the taken measures.
