Arthrosis Deformans

ZusammenfassungDieArthrose als schmerzhafte ein Gelenk deformierende Erkrankung ist nicht heilbar. Das Fortschreiten dieser Erkrankung kann durch eine Vielzahl konservativer Behandlungsmethoden herausgezögert werden, bevor endgültig eine operative Intervention, gelenkerhaltend oder als Gelenkersatz, erforderlich wird. Die zur Verfügung stehenden konservativen Behandlungsmethoden, veranlasst durch den Arzt unter Hinzuziehung von Physiotherapeuten oder Orthopädietechnikern werden vorgestellt.

Aquatic Treadmill

Introduction: Arthrosis is considered as a disease of the whole locomotor system, which may be prevented and treated at early stages. Gonarthrosis develops gradually within 10-15 years, interfering with daily activities and capability for work. Aquatic exercises are considered as a potentially effective therapeutic intervention in persons with knee arthrosis. Aim: Assessment of the effectiveness of a 4-week aquatic treadmill exercise programme, with respect to the measurement of pain, balance, function, and mobility. Materials and Methods: The study covered 15 patients with gonarthrosis, using a 4-week cycle of exercises. The results of measurements included a visual-analogue scale for assessing pain, Time Up and Go (TUG) for balance, 6-meter walk test for mobility and Lequesne index for function. The exercise protocol covered an aquatic treadmill using water jets to destabilize while standing, and achieve high ratings of perceived exertion during walking. Results: The comparison of results obtained by the patients after 20 interventions, with those obtained before therapy allowing the presumption that on the level of significance α= 0.05 there occurred statistically significant differences in the results of the tests performed (p<0.05). This concerned both pain complaints (VAS scale, Lequesne index of severity for arthrosis of the knee), as well as functional tests TUG, and measurement of the range of motion (p = 0.041-0.001). Conclusions: Based on the results of the study a decrease was observed in pain complaints, improvement of the range of motion in the joints, balance and function, after participation in a 4-week aquatic treadmill exercise programme, which contained the components of balance and endurance training.

Introduction: It is often difficult to clinically and radiologically diagnose intra-articular osteoid osteomas and osteoid osteomas of the hip joint. Treatment can also be difficult due to complex locational relationships. CT-guided radiofrequency ablation is currently the standard form of treatment. In this paper we report on a minimally-invasive concept for treating osteoid osteomas near the hip joint in children and adolescents which does not involve using computed tomography. Material and method: 10 patients with an average age of 12.1 years underwent treatment for osteoid osteomas in the hip joint region. The diagnosis was made using a contrast-enhanced MRI. The osteoid osteomas were marked percutaneously using x-ray and MRI guidance. MRI-guided drilling/curettage was performed in 4 cases and arthroscopic resection in 6 cases. Results: All lesions were successfully treated using the MRI-guided method. All patients were free of pain after the treatment. There was no instance of recurrence during the follow-up period, which averaged 10 months. The effective dose for marking the lesion was between 0.0186 mSv and 0.342 mSV (mean 0.084 mSV). Conclusions: Our MRI diagnostics protocol, the MRI-guided drilling and the minimally invasive hip arthroscopy represent an alternative to CT-guided radiofrequency ablation in the treatment of osteoid osteomas. Radiation exposure can thereby be significantly reduced. Hip arthroscopy can also be used to treat secondary pathologies such as femoroacetabular impingement.

The formation of single-phase solid solutions of iron oxide and manganese oxide with a spinel structure in MnxFe3 – xO4 system (x = 0; 0.3; 0.6; 0.8; 1.0; 1.2; 1.4; 1.8) has been established by methods of X-ray phase analysis and infrared spectroscopy. The maximum saturation magnetization was found for the composition Mn0.3 Fe2.7O4 (Ms = 68 A ⋅ m2 ⋅ kg−1 at 300 K and Ms = 85 A ⋅ m2 ⋅ kg−1 at 5 K), which is associated with a change in the cationic distribution over tetrahedral and octahedral voids. The materials obtained were stabilized in the form of colloidal solutions using a number of polyelectrolytes. It was found that poly(diallyldimethylammonium chloride) (PDDA) had the best stabilizing effect due to its structural features. A method for controlling the magnetic properties of magnetite by partial replacement of iron ions in the magnetite structure with manganese is proposed. Changing the magnitude of the magnetization and coercive force is possible by changing the degree of substitution. Relatively high values of specific magnetization, as well as uniformity of magnetic particles in size, can be of practical interest, for the manufacture of contrast agents in MRI diagnostics.
