Experiencia en el uso de colgajo de Becker para manejo de defecto de cobertura en aspecto dorso-cubital de la mano: análisis retrospectivo de 5 casos / Experience in the use of the Becker flap to manage coverage defects in the dorso-ulnar aspect of the hand: retrospective analysis of 5 cases

INTRODUCTION: Coverage defects of the hand and wrist are usually secondary to high-energy trauma, these must be resolved quickly to protect the underlying vital structures, preserve hand functions and allow early rehabilitation. The dorsal ulnar artery flap (Becker flap), in addition to being a non-demanding surgical technique, has the main advantage of preserving the main vascular axes of the forearm. MATERIALS AND METHOD: Retrospective descriptive study in patients with post-traumatic coverage defect in the dorsum-ulnar aspect of the hand, who were managed with a Becker flap between January 2015 and December 2018.Was analyzed age, sex, mechanism of injury, surgical time, size of the defect, type of donor site closure, complications, and functional outcomes/pain/satisfaction/range of motion with the Mayo Modified Wrist score. RESULTS: In total there were 5 cases, all male, with an average age of 53 (31-58) years, who suffered a high-energy trauma. There were 2 complications, one partial epidermolysis and one deep infection with loss of the flap. Follow-up time was 12 weeks for all cases. The results of the Mayo Modified Wrist Score on average were 72 points. CONCLUSION: The Becker flap is a reproducible, rapid dissection, non-demanding, and one-stage technique. The early use of this flap allows the preservation of vital structures, decreases morbidity, allowing early rehabilitation and an early return to work.

Enfermedad por Coronavirus - 2019 (COVID-19) y Traumatología: Revisión de la literatura / Coronavirus Disease - 2019 (COVID-19) and Traumatology: Review of Literature

The Coronavirus pandemic (COVID-19) triggered a global health emergency, and as a response, institutions and medical services have implemented different measures regarding the management of these patients in order to maintain medical care, and reduce the spread of the virus in patients and medical staff. The following review aims to present the current recommendations made by international, national and local societies regarding medical action from Traumatology and Orthopaedics. A literature review was done on Medline / Pubmed platforms, The Journal Bone and Joint Surgery (JBJS), Journal of the American Academy of Orthopedic Surgeons (JAAOS), Sociedad Chilena de Ortopedia y Traumatología (SCHOT). The literature was in Spanish and English, comparing it with reality on a local level. The current COVID-19 pandemic led to the complete reform of the trauma care units, starting with the development of subspecialty teams that rotate periodically, which are in charge of the emergency area, treating patients with all personal protection elements (PPE) and categorizing those patients who require emergency trauma surgery, from those that can be managed in a delayed manner. Regarding patients who are hospitalized, a COVID-19 PCR (Polymerase Chain Reaction) test is taken as screening, except for emergency surgeries where all intraoperative protection measures are taken. In addition, for greater safety, all elective surgery was suspended, which reduces the flow of patients in the ward and in the inpatient unit. Outpatient care was optimized in order to protect patients in their periodic check-ups.
