Orthopedic sports injuries: advanced imaging modalities, return-to-play criteria, and injury prevention

Orthopaedic sports injuries encompass a wide range of musculoskeletal conditions resulting from the physical demands of athletic activities. These injuries can vary from acute, such as sprains and fractures, to chronic overuse syndromes like tendinopathies. Prevalent due to the global enthusiasm for sports, they affect bones, muscles, tendons, ligaments, and joints. The etiology of these injuries is multifactorial, stemming from biomechanical stressors, training methods, genetics, and environmental conditions. Advanced imaging modalities like magnetic resonance imaging and Computed tomography have revolutionized the assessment and diagnosis of these injuries, aiding in treatment decisions and return-to-play criteria. Injury prevention is paramount and involves understanding intrinsic (athlete-related) and extrinsic (environmental) risk factors. Strategies include pre-participation screening, strength and conditioning programs, biomechanical analysis, neuromuscular training, proper equipment use, rule changes, education, and creating a safety-conscious culture. Effective prevention reduces the burden of these injuries. Treatment strategies range from conservative approaches to surgery, depending on the type and severity of the injury. Emerging trends in sports medicine, including biologic therapies and telemedicine, offer promising avenues for improved diagnosis and recovery. The holistic approach to orthopaedic sports injuries encompasses prevention, diagnosis, and treatment, ensuring athletes' well-being and longevity in their chosen sports.

Therapeutic effect of work intensive training on workers with musculoskeletal injury / 中国职业医学

OBJECTIVE: To observe the therapeutic effect of work intensive training on workers with musculoskeletal injury(MSI). METHODS: A convenience sampling method was used to select MSI patients as research subjects. Patients were randomly divided into control group(179 cases) and experimental group(188 cases). On the basis of the conventional comprehensive rehabilitation treatment, the control group received the routine occupational rehabilitation intervention, and the experimental group received the work intensive training intervention. The intervention period was 4 weeks in both groups. We used the Post-Traumatic Stress Disorder(PTSD) Self-Rating Scale, the Fear-Avoidance Beliefs Questionnaire(FABQ) and the General Self-efficacy Scale(GSES) to assess the recovery of MSI patients. The statuses of return to work of patients were followed up by telephone after six months of discharge from hospital. RESULTS: Compared with the same group before intervention, the scores of PTSD, FABQ-P and FABQ-W in the control group and the experimental group decreased, and the score of GSES increased(P<0.01). After the intervention, the scores of PTSD, FABQ-P and FABQ-W in the experimental group were lower than those in the control group(P<0.01), and the score of GSES was higher than those in the control group(P<0.01). The rate of returning to work in the experimental group was higher than that in the control group(80.9% vs 59.2%, P<0.01). CONCLUSION: Work intensive training has curative effect on self-efficacy, physical activity, subjective pain, and post-traumatic stress disorder, and can improve the rate of resuming to work in patients with MSI.

Design and application of a new patient transfer device / 中华危重病急救医学

In daily medical work, most of the critically ill patients who cannot move by themselves are pulled and lifted by manpower, often relying on the cooperation of many doctors and nurses, which not only increases the risk of transfer and patients' discomfort, but also causes certain skeletal and muscle damage to the porters. The emergency department of the First Hospital of Jiaxing City, Zhejiang Province designed a kind of patient transfer device, and obtained the National Utility Model Patent (ZL 2018 2 0579844.X). The transfer device is composed of upper frame, lower frame and base. The upper frame and the lower frame are rectangular and in a horizontal position. The upper frame can slide laterally through the circular tubes which are fixed on the lower frame. The lower part of the base is provided with four universal foot brake wheels. During the usage, the booster frame facilitates the transfer of patients by the rolling and two sliding tracks of the circular tube, which can make patients move smoothly and comfortably, and reduce the working intensity of the transporter. This device has good practical value.
