The surgical meshes selection, according to the structure and porosity of the biomaterial type and meshes design, is directly dependent on the surgical procedure used and interaction between biomaterial type and abdominal viscera. Surgical mesh must provide sufficient biomechanical strength in order to assure the physiological requirements in order to protect the soft tissue defects. The large variety of biomaterials used in abdominal surgery and the multitude of surgical fixation procedures show that we are still far from the ideal prosthesis. The main objective of this paper is to determine the effect of the sterilization procedures of some surgical meshes, with different design and made of different materials, on their structure and properties of interest. Experimental research was conducted on three types of surgical meshes, different from material and design point of view. Fourier Transform Infrared (FTIR) Spectroscopy was used to evaluate the structural characteristics of the samples. In the evaluation of the surface properties, scanning electron microscopy (SEM) was used for the qualitative assessment of surface morphology and contact angle determinations (CA) to determine the wettability properties. The sterilization process used was chemical sterilization with ethylene oxide, a procedure used by surgeons in clinical practice. According to the experimental research, the negative effects of the sterilization process on surgical meshes used in abdominal surgery are accentuated for the samples sterilized with ethylene oxide for three times, while their sterilization only one cycle does not significantly affect the surface properties and tensile strength of surgical meshes, regardless of the design and material of which they are composed.

Evolution of hernia surgery has led to polymeric biomaterials for replacement or reinforcement of the abdominal wall. Their selection, according to the structure and porosity of the material, is directly dependent on the surgical procedure used and interaction between material and abdominal viscera. The objective of the paper is to establish a protocol for the selection of hernia mesh fixation materials based on polymer structure related to the surgical procedure used. The biomaterials that promote infection should be avoided and those that do not provide a long-term mesh placement should be used in combination with other devices to compensate for this fault. In conclusion, is much better to adapt the fixation biomaterials used in clinical practice to the specific surgical procedure, given the physical and chemical characteristics of these polymers, in order to reduce the morbidity associated with this type of surgery.

Broad introduction and development of polymeric materials in abdominal hernia surgery led to the emergence and identification of secondary complications due to interaction between prosthetic material and human tissue. Whether identification of these reactions has led to the placement instructions of the prostheses into the wall structures of adbomen, there is no clear rule on fixation materials of these prosthesis; they generally follow the recommendations of the prosthesis materials.There are some situations in which the faulty choice of fixing materials can compromise such surgery, followed by chronic septic complications and negative effect on quality of life of these patients and increased risk of recurrence.The choice of fixing materials considering the structural characteristics of polymeric threads can prevent chronic suppuration secondary to this type of surgery.

The purpose of this article was to analyze bone metastases as being the most common site of recurrence of breast cancer. Bone metastases secondary to breast cancer have a negative impact on patient survival, mobility and quality of life. In addition, the clinical complications of bone cancer metastases of breast cancer are associated with a significant financial burden for the individual and society. This article summarized the implications of breast cancer musculoskeletal metastases based on clinical application in an emergency hospital, including patient workup, procedural strategy and techniques.
