Introduction. The osteosarcoma represents the most frequently encountered primitive malignant bone tumor, representing 30% of the malignant bone tumors with an unpredictable evolution. Materials and methods. A retrospective study realized over a period of 3 years (Jan. 2016-Jan. 2018), which included 6 patients diagnosed with osteosarcoma and treated through the reconstruction with tumor prosthesis technique in the Orthopaedics and Traumatology Clinic of the University Emergency Hospital in Bucharest. Results. Of the total 6 patients, 5 were male and 1 was a female with ages between 20 and 61 years old, with an average of 30.6 years. The localization of the tumor was at the distal femur (3 cases) and at the proximal tibia (3 cases). In 3 cases, the reattachment of the extensor apparatus of the knee to the prosthesis was needed, while for 3 of the cases, a musculocutaneous flap was created for the coverage of the implant. All the 6 patients were monitored and had postoperative follow-ups at 3, 6 and 12 months by having clinical and imagistic evaluations in search of the eventual local recurrences or metastases in other tissues and organs. The postoperative evaluation of the function of the joint was realized with the Knee Society Score Questionnaire and recorded very good results (76-91) with an average of 82 points. Conclusions. The short-term results of this study about the treatment of the knee osteosarcoma with modular prostheses show that this treatment has a low tumoral recurrence rate and restores the joint function.

Objective: The aim of this study was to asses the frequency of the deafness pathology in the Ear, Nose and Throath Clinic of the Emergency County Hospital in Tîrgu Mureș and two other private institutions that have an ear linked profile, with a special interest on those with indication for prosthesis. This is a pilot study, being conceived as a part of a larger one used to measure the number of possible cochlear implant recipients nationwide.
Methods: We gathered data from the interval 2011-2013, including in the study all the patients for which an audiometry testing was performed in this time interval. This was followed by a process of selection/exclusion applied to the original group in order to obtain significant statistical data.
Results: The most important part of the study was to quantify the different types of hypoaccusia and the relative number of candidates for various prosthesys available these days.
Conclusions: This study quantifies the rising need for hearing prosthesis and triggers a signal.

The decision-making model with basic fuzzy rule modus ponens is suggested in this paper to control the hand prosthesis. The hand movements are described by angles of finger and wrist flexion. Electromyogram (EMG) of hand muscles was used as a source of the input data. Software was developed to implement the decision-making model with fuzzy rule modus ponens. In particular, the software receives EMG data, executes calculations and visualises the output data. The key advantage of the model is smoothness of output data changes; this way a maximum approach to natural hand movements is reached.
