Medial Proximal Tibia Physeal Overuse Injury of an Athlete.

Overuse injuries are well described for both upper and lower extremities among skeletally immature athletes. To our knowledge, there is no description in the literature of an overuse injury affecting the medial tibial physis that is different from the typical Osgood-Schlatter disease or tibial tubercle apophysitis. In this article we present a 13-year-old athlete with medial proximal tibial widening or epiphysiolysis from overuse playing soccer. We need to be aware that with increased early sports specialization we may see injuries we have not seen before. [Orthopedics. 2022;46(6):e345-e347.].

Rationale and process for N95 respirator sanitation and reuse in the coronavirus disease 2019 (COVID-19) pandemic.

OBJECTIVE: The novel severe acute respiratory coronavirus virus 2 (SARS-CoV-2) was first reported in Wuhan, China, in December 2019 and is notable for being highly contagious and potentially lethal; and SARS-CoV-2 is mainly spread by droplet transmission. The US healthcare system's response to the COVID-19 pandemic has been challenged by a shortage of personal protective equipment (PPE), especially N95 respirators. Restricted use, reuse, and sanitation of PPE have been widely adopted to provide protection for frontline healthcare workers caring for often critically ill and highly contagious patients. Here, we describe our validated process for N95 respirator sanitation. DESIGN: Process development, validation, and implementation. SETTING: Level 1, urban, academic, medical center. METHODS: A multidisciplinary team developed a novel evidence-based process for N95 respirator reprocessing and sanitation using ultraviolet (UV) light. Dose measurement, structural integrity, moisture content, particle filtration, fit testing, and environmental testing were performed for both quality control and validation of the process. RESULTS: The process achieved UV light dosing for sanitation while maintaining the functional and structural integrity of the N95 respirators, with a daily potential throughput capacity of ∼12,000 masks. This process has supported our health system to provide respiratory PPE to all frontline team members. CONCLUSIONS: This novel method of N95 respirator sanitation can safely enable reuse of the N95 respirators essential for healthcare workers caring for patients with COVID-19. Our high-throughput process can extend local supplies of this critical PPE until the national supply is replenished.

Utilization of an Orthopedic Hood as Personal Protective Equipment for Intubation of Coronavirus Patients: a Brief Technical Report.

BACKGROUND: The novel coronavirus disease (COVID-19) has afflicted millions of people worldwide since its first case was reported in December 2019. Personal protective equipment (PPE) has been tailored accordingly, but as of April 2020, close to 10 000 health care workers in the United States have contracted COVID-19 despite wearing recommended PPE. As such, standard guidelines for PPE may be inadequate for the health care worker performing high-risk aerosolizing procedures such as endotracheal intubation. In this brief technical report, we describe the integration of an orthopedic hood cover as an item for full barrier protection against COVID-19 transmission. TECHNICAL DESCRIPTION: The Coronavirus Airway Task Force at Virginia Commonwealth University Medical Center approved this initiative and went live with the full barrier suit during the last week of March 2020. The PPE described in this report includes a Stryker T4 Hood, normally used in conjunction with the Stryker Steri-Shield T4 Helmet. Instead of the helmet, the hood is secured to the head via a baseball cap and binder clip. This head covering apparatus is to be used as an accessory to other PPE items that include an N95 mask, waterproof gown, and disposable gloves. The motor ventilation system is not used in order to prevent airborne viral entry into the hood. DISCUSSION: An advantage of the full barrier suit is an additional layer of droplet protection during intubation. The most notable disadvantage is the absence of a ventilation system within the hood covering. CONCLUSION: Modification of existing PPE may provide protection for health care workers during high-risk aerosolizing procedures such as endotracheal intubation. Although the integration of this medical equipment meets the immediate needs of an escalating crisis, further innovation is on the horizon. More research is needed to confirm the safety of modified PPE.

Acute post-operative airway complications following anterior cervical spine surgery and the role for cricothyrotomy.

Anterior cervical spine surgery (ACSS) is a common procedure, but not without its own risks and complications. Complications that can cause airway compromise occur infrequently, but can rapidly lead to respiratory arrest, leading to severe morbidity or death. Knowing emergent post-operative airway management including surgical airway placement is critical. We aim to review the different etiologies of post-operative airway compromise following ACSS, the predictable timeline in which they occur, and the most appropriate treatment and management for each. We place special emphasis on the timing and proper surgical technique for an emergent cricothyrotomy. Angioedema is seen the earliest as a cause of post-operative airway compromise, typically within 6-12 hours. Retropharyngeal hematomas can be seen between 6-24 hours, most commonly within 12 hours. Pharyngolaryngeal edema is seen within 24-72 hours. After 72 hours, retropharyngeal abscess is the most likely etiology. Several studies have utilized delayed extubation protocols following ACSS based on patient risk factors and found reduced postoperative airway complications and reintubation rates. The administration of perioperative corticosteroids continues to be controversial with high-level studies recommending both for and against their use. Animal studies showed that after cardiac arrest, the brain can recover if oxygenation is restored within 5 minutes, but this time is likely shorter with asphyxia prior to cardiac arrest. Experience and training are essential to reduce the time for successful cricothyrotomy placement. Physicians must be prepared to diagnose and treat acute postoperative airway complications following ACSS to prevent anoxic brain injury or death. If emergent intubation cannot be accomplished on the first attempt, physicians should not delay placement of a surgical airway such as cricothyrotomy.

Diagnosis of lower-extremity deep vein thrombosis in outpatients with musculoskeletal disorders: a national survey study of physical therapists.

BACKGROUND AND PURPOSE: Prompt identification of outpatients who may have proximal lower-extremity deep vein thrombosis (PDVT) is important, in part, because of the risk of pulmonary embolism. The purposes of our study were to determine the degree of accuracy of physical therapists' estimates of the probability of PDVT in hypothetical patient vignettes and to determine whether physical therapists would contact the referring physician about the hypothetical patients' condition as recommended in published evidence. SUBJECTS AND METHODS: A survey instrument consisting of 6 vignettes was sent to a nationally representative random sample of 1,500 physical therapists. The clinical decision rule developed by Wells and colleagues served as the gold standard for PDVT probability. RESULTS: A total of 969 (65% response rate) physical therapists completed the survey. We found no evidence of nonresponse bias. For the 2 high-probability vignettes, 87% and 64% of the physical therapists underestimated the probability of PDVT. For the 2 high-probability cases, 32% and 27% of the physical therapists reported that they would not have contacted the referring physician. For the 2 moderate-probability cases, 15% and 30% of the physical therapists would not have contacted the referring physician. Therapist experience, certification status, place of practice, and region of the country did not explain the findings. DISCUSSION AND CONCLUSION: The care of outpatients who are at risk for PDVT could potentially be improved by use of the clinical decision rule developed by Wells and colleagues, although more study is warranted.
