Opis:: W artykule przedstawiono metodę inżynierskiego wspomagania neurochirurgicznych zabiegów stabilizacji odcinka szyjnego kręgosłupa. Dzięki modelowaniu możliwe było przeprowadzenie analizy wytrzymałościowej modelu odcinka szyjnego kręgosłupa wraz z umieszczonym w nim implantem sztucznego dysku. Wykonane obliczenia pozwoliły określić oddziaływanie implantu na kręgosłup oraz wyznaczyć naprężenia wewnętrzne występujące w kręgosłupie, przy zasymulowanym obciążeniu.
The method of engineering support in neurosurgical operations concerning the stabilization of human cervical spine was presented in the article. Thanks to the modelling it was possible to conduct a durability analysis of the model of the cervical spine with the artificial disc implant placed in it. The calculations that were carried out, allowed to determine both the implant's influence on the spine and the internal stresses occurring in the spine with a stimulated strain.

Opis:: Ailments linked to back pain is a serious problem not only medical but also social. Not only elder people but also people in working age suffers from problems related to spine pain. The most common disorders of the spine are pain syndromes of the lumbar part where center of gravity of the human body is located and w here major forces are acting on the vertebrae and intervertebral discs. The market currently offers a variety of spinal implant solutions (FIG 1). In the Metal Forming Institute there is realized research Project entitled Investigations and spine implants functionality evaluation in material and tribological aspects. In the frame of the Project it was designed and manufactured special simulator adapted for intervetebrals pine discs implants investigations. Simulator scheme is presented on FIG. 2. Main goals of the realized Project are: • Investigation of friction-mechanical processes during implant usage. • Evaluation of wear intensity of various types of intervertebral discs and investigations of appearing wear products. • Selection of optimal material and surface machining method providing minimal wear of intervertebral disc elements wear. For experiments there was implant designed by K. Skalski and J. Skoworodko selected [1], which consists of 3 elements: upper liner, lower liner and nucleus pulpous (FIG. 3). Actually there are 3 types of friction couple materials tested: 316L steel - polyethylene UHMWPE – 316L steel, titanium alloy Ti6Al4V – polyethylene UHMWPE and nitrided Ti6Al4V titanium alloy – polyethylene UHMWPE. In fluence of number of cycles on friction coefficient, surface roughness and poliethylene linner thickness change illustrates FIG. 4. As it results from performed investigations, too high hardness level of metal elements (upper and lower clasps) provides to accelerated wear of the polyethylene part. New challenge is application of “metal-metal” friction couple.

Opis:: As the lumbar region of the spine is particularly predisposed to musculoskeletal disorders, the aim of this article was to assess lumbar spine load on the basis of an accurate model of this part of the body. The model was developed with the finite element method and the energy criterion for optimising muscle work. Computer calculations confirmed that stresses and compression forces in intervertebral discs increased with an increase in the load force and that they were significantly larger in the bent forwards posture than in the erect posture. This result clearly shows that lifting light objects and the erect posture are important elements in minimising spine load.

Opis:: Though cervical spine disorders occur less frequently than lumbar spine problems, their course and final results may have severe implications for patients. Despite significant development in operative treatment of cervical spine; patients, if possible, choose conservative methods basing mainly on pharmacotherapy and rehabilitation (physiotherapy). A case report of non-operative treatment with use of selected techniques of manual therapy and physiotherapy is described. Achieved improvement allowed postponing the surgery, but we cannot exclude the necessity of operation in the future.

non-specific lumbar spine pain syndromes
Opis:: Non-specific lumbar spine pain syndromes (nslsp) are currently the most common ailment. There are many physiotherapeutic methods that reduce pain and improve the functional status of patients. One of them is Bowen Technique (BT), which is a little-known fascial therapy and is characterized by a holistic approach to the patient. The aim of the study was to assess the effectiveness of BT in patients with non-specific lumbar spine pain syndromes. We examined 50 patients aged 25-60 (the average age was 39.92, SD ± 9.510, median 37.0). An interview was conducted with each patient. Functional examination based was done four times. It included Revised Oswestry scale, Low Back Pain Disability Scale measurements of the range of motion of the lumbar spine and Visual analogue scale (VAS) was used to describe the pain of patients. Eeach patients attended into three procedures of Bowen Therapy. The pain in the lumbar spine decreased after the first TB and its level is constantly reduced with each subsequent procedure. Analyzing all subjects, statistically significant differences were visible between the state before therapy and each subsequent examination, as well as between the first and the third treatment. In the subjects, the health condition is improved, and more precisely, the intensity of pain, the frequency of its occurrence and the increase in independence were reduced. A study showed that there was a statistically significant improvement in patients' health due to therapy. The ranges of motion of the lumbar spine as a result of the therapy increased. The assessment of TB therapy after the first treatment is mostly good, and after the third 66% of respondents assess as very good. The number of patients who are very satisfied with the effectiveness of the treatment increases from the procedure to the procedure.

Opis:: Purpose: The aim of this paper is to present the novel model for the functional spinal unit and spine designed as a rigid mechanism and solve it with methods commonly used in robotics. Method: The structure of the intervertebral joint is analyzed with special attention paid to elements defining the displacements in the joint. The obtained mechanism is then numerically solved using a constraint equations method. Results: The input data set for the simulation is prepared using the 3D scan of the lumbar spine. The simulation results show that the intervertebral joint mechanism can satisfy the ranges of flexion, lateral bending and axial rotation as compared with literature data. It is also possible to study complex, coupled displacements of the lumbar spine segment. Conclusions: Structural analysis of the functional spinal unit with methods common in robotics can eventually lead to better understanding of stabilizing and guiding mechanisms. The proposed mechanism can be used as a reference in the study of spine guidance. It can reproduce the angular displacements of the actual functional spine unit. It is also possible to expand the model to facilitate the analysis of a lumbar spine segment.

Opis:: Aim. The aim of the study was to review the literature on the prevalence of cervical spine injuries divided between the level of the injury and the causes of fractures. Material and methods. A review of Polish and foreign literature was performed. The following databases were searched: PubMed, Medline, Science Direct, Termedia, and Polish Medical Bibliography. Literature analysis. In Poland the incidence of spinal injuries, including damage to the cord, is estimated at the level of 25–35 persons per one million of the population, half of these being cervical spine injuries. More than one in three of all spinal injuries affect the atlantoaxial and occipital area. It is estimated that axis fractures occur in up to 40% of the cases involving cervical spine injury. Odontoid fractures constitute 10–15% of all cervical spine fractures. Hangman fractures account for 20% of vertebral fractures. Cervical spine injuries more frequently occur in males than in females, and the relevant rates for males are from 1.5 to 2.7 times higher. The most common causes of cervical spine injuries include road traffic accidents, accounting for 33 to 75% of the cases, falls from heights (15–44%) and sports injuries (4–18%). Cervical spine injuries are most often diagnosed in subjects over thirty years of age. Such injuries most commonly are related to the second, fifth and sixth cervical vertebrae. On the other hand damage to the first and second cervical vertebrae is often observed in the same patients who are found with injury to lower cervical vertebrae (approx. 9% of the cases). In the group of advanced age subjects the most frequent cervical spine injuries are axial fractures and they are diagnosed in 15% of adult patients with cervical spine fractures.

Opis:: Most of the pathological changes in the spine begin with the physiological loss of intervertebral disc function. Discopathy of the lumbar spine leads to a significant deterioration in the quality of life, which is why the therapeutic team strives is to improve patients quality of life through actions aimed at reducing spinal dysfunction to an extent that allows for human functioning. The research aim was to determine the quality of life of patients who had been treat- ed as a result of discopathy of the lumbar spine and to establish the relationship between the experience of negative feelings and a subjective assessment of the quality of life with factors resulting frompatient socio-demographics. The study included 110 patients treated for lumbar discopathy. A diagnostic survey method was employed as a research technique, with the use of a proprietary survey questionnaire. Statistic analysis of the results was performedusing the statistical package PQStat v1.6.6. Subjective evaluation of patients quality of life in 66 persons (60%) was at an average level, only 6 (5.45%) respondents rated the quality of their lives as being higher. Those living in towns of up to 50,000 residents rated their quality of life higher (6.21), with the lowest level being reported by those living in the countryside (4.95). Age did not influence significantly the quality of life, but older people most often experienced pain (p=0.4). Analysis of variance did not show statistically significant differences between marital status and respondent quality of life (p = 0.53) but did show significant differences between education levels and the incidence of negative feelings such as fear, anxiety or depression. Socio-demographic variables: such as gender, age and marital status do not significantly differentiate the quality of life of the respondents. There is a relationship between experiencing negative feel ings and educational levels. The lower the education level obtained, the more often negative feelings are experienced. The experiencing of negative feelings and disease duration are variables that reduce the quality of life of respondents. ------------------------------------------------------------------------------------------------------------------------------------
