[Competence perception survey among residents of orthopedics and trauma in a hospital of Yucatán México].

Background: The competence model states that what is most important is to have the elements to solve problems since abstract training does not provide enough tools to solve them. Therefore, it uses key and auxiliary competences that are linked to values such as attitudes. This study was performed to explore these competences.

[Multiple cervical spine fractures. Case report].

Introduction: Multiple cervical spine fractures are a relatively infrequent entity and thus the available information on them is scarce worldwide. The cases reported are usually managed conservatively, with a combination of skeletal traction and various braces, with variable results. There are only a few reports of multiple fractures treated surgically.

[Effect of early versus late rehabilitation in patients with Achilles tendon tenorrhaphy].

Background: Achilles tendon tear is a prevalent condition in our setting. There is no consensus in the literature regarding the ideal treatment modality or the right immobilization period before starting physiatrics. The harmful effect of prolonged immobilization is widely known, so the functional results of early versus late physical therapy are compared in patients subjected to surgery for Achilles tendon tear.

[Effect of a short antimicrobial prophylaxis regimen on the prevalence of postoperative infection in elective orthopedics and traumatology surgery].

Objective: To assess the efficacy of two antimicrobial prophylaxis regimens, a short cycle and the standard one, on the prevalence of acute postoperative infection in orthopedic surgery for acute and chronic disease of a thoracic and a pelvic limb.

Material And Methods: Prospective, observational, experimental randomized, double-blind trial in patients undergoing orthopedic surgery due to acute or chronic disease, between April and September 2009. The sample size was determined using the formula to calculate the finite population.
