Design of a perceived quality scale in orthopaedic surgery education.

Objectives: The experience of students contributes to proactively identifying the changes necessary in training approaches and activities. The main objective of the Institutional Evaluation Programme was to design and validate a tool that permits discerning the experience of students from traumatology teaching.

Methods: Lecturers from the Orthopaedic Surgery Teaching Unit and experts in quality evaluation methodology, prepared the initial items.

A Spanish-language patient safety questionnaire to measure medical and nursing students' attitudes and knowledge.

Objective: To design and validate a questionnaire for assessing attitudes and knowledge about patient safety using a sample of medical and nursing students undergoing clinical training in Spain and four countries in Latin America.

Methods: In this cross-sectional study, a literature review was carried out and total of 786 medical and nursing students were surveyed at eight universities from five countries (Chile, Colombia, El Salvador, Guatemala, and Spain) to develop and refine a Spanish-language questionnaire on knowledge and attitudes about patient safety. The scope of the questionnaire was based on five dimensions (factors) presented in studies related to patient safety culture found in PubMed and Scopus.

Injectable and self-curing composites of acrylic/bioactive glass and drug systems. A histomorphometric analysis of the behaviour in rabbits.

Injectable self-curing systems based on PMMA, phosphate-free bioactive glasses and the drug fosfosal, a phosphate derivative of salicylic acid with analgesic and moderate anti-inflammatory properties, have been tested in vivo to evaluate their biocompatibility. The model consisted of the injection of dough of cement into a defect created in the femur of rabbits, and the cure of the cement in situ after implantation. The biological response was studied in the short and long terms by macroscopic, radiological and histopathological examination, and quantitatively by histomorphometric and statistical analysis considering the most representative variables at the bone-cement interface: cement, bone marrow, newly formed bone and connective tissue.

Conservative management of burst fractures of the fifth lumbar vertebra.

Isolated fractures of the lumbar fifth vertebrae (L5) are very rare, and there is little information in the literature regarding comparisons between conservative management and surgical treatment of this entity. This retrospective analysis reports on five cases of isolated burst fractures of the fifth lumbar vertebra without neurologic deficit. All cases were managed nonoperatively with a short period of bed rest followed by protected mobilization.
