RESUMO
Muscle injuries are the most common sports-related injuries, with hamstring involvement most common in professional athletes. These injuries can lead to significant time lost from play and have a high risk of reinjury. We review the anatomy, mechanisms of injury, diagnostic imaging modalities, and treatment techniques for hamstring injuries. We also present the latest evidence related to return to play (RTP) after hamstring injuries, including a review of articles targeted to RTP in European soccer (Union of European Football Associations), American football (National Football League), and other professional sports. Review of imaging findings in hamstring injury, grading systems for injuries, considerations for RTP, as well as advances in injury prevention, are discussed.

This review surveys concussion management, focusing on the use of neuroimaging techniques in return to play (RTP) decisions. Clinical assessments traditionally were the foundation of concussion diagnoses. However, their subjective nature prompted an exploration of neuroimaging modalities to enhance diagnosis and management. Magnetic resonance spectroscopy provides information about metabolic changes and alterations in the absence of structural abnormalities. Diffusion tensor imaging uncovers microstructural changes in white matter. Functional magnetic resonance imaging assesses neuronal activity to reveal changes in cognitive and sensorimotor functions. Positron emission tomography can assess metabolic disturbances using radiotracers, offering insight into the long-term effects of concussions. Vestibulo-ocular dysfunction screening and eye tracking assess vestibular and oculomotor function. Although these neuroimaging techniques demonstrate promise, continued research and standardization are needed before they can be integrated into the clinical setting. This review emphasizes the potential for neuroimaging in enhancing the accuracy of concussion diagnosis and guiding RTP decisions.

OBJECTIVE: The primary purpose of this study was to examine concussion management practice patterns among sports medicine physicians in the United States. DESIGN: Cross-sectional study using a web-based survey. PARTICIPANTS: Members of the American Medical Society for Sports Medicine (AMSSM). MAIN OUTCOME MEASURES: We distributed a questionnaire to physician members of the AMSSM assessing the current practices for evaluating and managing concussions sustained during sports. Specifically, we asked respondents about their use of management guidelines, medications, balance assessments, neuropsychological tests, and return-to-play strategies. RESULTS: Of the 3591 members emailed, 425 (11.8%) respondents responded. Ninety-seven percent of respondents reported basing current management of sport-related concussion on a published set of criteria, with a majority (91.9%) following the guidelines provided by the Fourth International Conference on Concussion in Sport. Seventy-six percent of respondents reported using medication beyond 48 hours postinjury. Acetaminophen was reported as the most commonly administered medication, although tricyclic antidepressants and amantadine were also commonly administered. Vitamins, minerals, and dietary supplements were also reported as commonly administered. Most respondents reported using a form of neuropsychological testing (87.1%). A majority of respondents (88.6%) reported allowing athletes to return to competition after concussion only once the athlete becomes symptom free and completes a return-to-play protocol. CONCLUSIONS: Most sports medicine physicians seem to use recently developed guidelines for concussion management, regularly use medications and neuropsychological testing in management strategies, and follow established return-to-play guidelines. CLINICAL RELEVANCE: Sports medicine physicians seem to have clinical expertise in the management of sport-related concussion.

BACKGROUND: Despite recent research, nonprescription pain medication use among collegiate athletes across all divisions of the National Collegiate Athletic Association (NCAA) is still not well understood. HYPOTHESIS: Non-Division I-A NCAA athletes have a different usage pattern of nonprescription pain medication than NCAA Division I-A football athletes. METHODS: A modified version of a nonprescription medication usage survey that had been used with Division I-A football athletes was distributed to Division II and Division III athletes during pre-participation exams. The statistics were analyzed by calculating the z-ratio for the significance of the difference between 2 independent proportions. RESULTS: A total of 198 athletes from 16 different sports were surveyed. It was found that 62% of athletes used nonprescription medications for sports-related pain, which was significantly lower than previous findings for Division I-A football athletes: 12% reported taking more than the recommended dose; 1.5% reported taking nonprescription pain medication for > 10 consecutive days; and 38% reported that they read the label the first time they took a new nonprescription pain medication. These results, when compared with findings on Division I-A football athletes, demonstrated that Division II and III athletes are less likely to take more than the recommended dose of nonprescription pain medications and are less likely to use the medications for > 10 consecutive days-characteristics that are used to define misuse. Similar results were found when comparing Division I-A football athletes with non-Division I-A football athletes. CONCLUSIONS: Athletes from NCAA Division II and Division III sports appear to use nonprescription pain medication for sports-related pain less often and have lower rates of misuse than do Division I-A football athletes. Division I-A football athletes may be more likely to misuse nonprescription pain medication than non-Division I-A athletes. Special attention should be paid to this population to help reduce adverse event risks.

Background Spinal stenosis is a degenerative narrowing of the spinal canal with encroachment on the neural structures by surrounding bone and soft tissue. This chronic low back condition can cause restrictions in mobility, impairment of daily activities, opioid dependence, anxiety, depression, and reduced quality of life. Spinal stenosis can be treated through surgical and nonsurgical methods, but neither has proven consistently reliable. Cannabidiol (CBD) has also been observed to have anxiolytic, anti-inflammatory, antiemetic, and antipsychotic behaviors. CBD may provide greater nonsurgical treatment options for the pain associated with spinal stenosis while minimizing the need for opioids. An observational study was undertaken to assess the effects of CBD on patients suffering from chronic spinal stenosis. Methodology This observational study was investigator-initiated and designed to determine the effect of hemp-derived CBD gel caps for patients with spinal stenosis related to low back pain and leg pain relative to patient outcomes, medication utilization, and quality of life outcome measures. A total of six physician visits would be required where a set of surveys would be filled out each four weeks apart. Results The study population consisted of 48 patients. The patient population's age ranged from 63 to 95 years and was normally distributed, with a mean age of 75 ± 7.13 years. The sex distribution was 33% male and 67% female patients. The pain was broken down between the six visits for each of the following four questions: pain right now, usual pain level during the week, best pain level during the week, and worst pain level during the week. Usual pain levels (p < 0.001) and worst pain levels (p < 0.005) demonstrated statistically significant improvement over time, while pain right now (p > 0.05) and best pain level (p > 0.05) stayed consistent throughout without statistical significance. Conclusions This open-label, prospective, observational study found that treatment with hemp-derived CBD gel caps was associated with significant improvements in pain scores and several quality-of-life measures for patients with lumbar spinal stenosis.
RESUMO
Nationwide perspectives on cannabis have changed dramatically over recent decades. Although cannabis remains illegal at the federal level, medical cannabis (MC) is now legal in most states, and research has continued to show its effectiveness in a variety of medical conditions. However, both perception and acceptance of MC by the general public are evolving and remain poorly understood. Treating patients effectively with these novel therapeutics requires an understanding of the complex interplay of social and legal factors that could affect patient use. This cross-sectional survey study of more than 2500 patients sought to assess current patient perspectives on MC and to investigate factors related to its use that may represent barriers to broader patient use. Most respondents would consider using MC for chronic pain or other medical conditions. Most respondents were aware of the legal status of MC in their state, and 9 of 10 respondents believed that MC should be legal throughout the United States. General public knowledge of the utility of MC is an area needing improvement because older patients were significantly less likely to believe that MC is safe to use or that MC is safer than prescription opioids. As has been reported in previous literature, social stigma and cost appear to remain barriers for patient use of MC. Our findings provide further insight into current patient perspectives on MC, aiding both medical providers and researchers as we continue to provide access to and research MC.

Some patients require emergent, urgent, or elective surgery in the time period immediately following diagnosis of concussion. However, changes in brain homeostatic mechanisms following a concussion and concern for secondary brain injury can complicate the decision as to whether or not a surgery should proceed or be postponed. Given the paucity of available evidence, further evaluation of the use of anesthesia in a patient with concussion is warranted. This article summarizes what is currently known about the relevant pathophysiology of concussion, intraoperative anesthesia considerations, and effects of anesthesia on concussion outcomes in an attempt to help providers understand the risks that may accompany surgery and anesthesia in this patient population. While most contraindications to the use of anesthesia in concussed patients are relative, there are nonetheless pathophysiologic changes associated with a concussion that can increase risk of its use. Understanding these changes and anesthetic implications can help providers optimize outcomes in this patient population.

Intention to resume high-risk sports activity is a major motivating factor for patients who elect anterior cruciate ligament (ACL) reconstruction rather than nonoperative treatment. Some patients are able to cope with an ACL-deficient knee and resume preinjury activity levels, including level-1 sports (football, basketball, soccer, etc.), following nonoperative treatment; however, activity levels correlate with injury risk in ACL-deficient knees. Patients who have an ACL injury along with concomitant meniscal injury are at increased risk for osteoarthritis. It is unclear what effect reconstruction of an isolated ACL injury has on future osteoarthritis risk in ACL-deficient patients who are identified as "copers." There are distinct biomechanical differences between copers and noncopers, but no reliable screening tools are currently able to predict which patients will become copers following nonoperative treatment of an ACL injury. A trial of nonoperative treatment, including perturbation exercises, to determine whether reconstruction is needed does not increase the risk of additional knee injury.
