We investigated the factors which influence the musculoskeletal symptoms in diagnostic medical sonographer. The Korean Society of Medical Sonographer conducted a survey through e-mail. Of the 400 subjects, 124 subjects responded(31%). The number of abdominal sonographer was 72(71.3%), obstetrics sonographer was 20(19.8%), echocardiographer was 9(8.9%) for effective 101 participant among themselves. According to the NIOSH diagnostic criteria, 86 subjects(85.1%) had musculoskeletal symptoms on their shoulders/neck, 73 subjects(72.3%) on their hands/wrists/arms/elbows, 44 subjects(43.6%) on their lower back. The factor of musculoskeletal symptoms were analyzed by the logistic regression analysis. The factors of symptoms for the hands/wrists/arms/ elbows were official autonomy, number of scans performed per week. The factors of symptoms for the shoulders/neck and the lower back were work break. However scan type were not observed as a significant factor. The study came to conclusion that many study subjects experienced musculoskeletal symptoms. These measures should be taken properly and promptly by the hospital's administrators.

Medial knee joint pain is a common problem in the field of orthopedics. In these patients, a high resolution ultrasound examination can reveal medial collateral ligament (MCL) bursitis, meniscal cyst, degeneration changes to the MCL and meniscal protrusion etc. Prolotherapy is effective in these patients. The author performed prolotherapy for MCL bursitis of the knee joint, and confirmed the disappearance of the bursitis using high resolution ultrasound.

Musculoskeletal ultrasound has unique advantages that may be free from exposure to radiation, low price compared to MRI, outpatient procedure that can be easily accessible, and better accuracy combined with physical examination. Dynamic ultrasound performed with stress tests are known to be useful for detecting the hidden lesions in the tendons, ligaments, nerves. Ultrasound in the elbow can be used easily in the outpatient for evaluation of the joint surface and synovial space; diagnosis for tendon diseases such as lateral epicondylitis, medial epicondylitis and morbidity of peripheral nerves; guide for anterior-posterior bursal and intra-articular injections.

Prolotherapy, the technology for strengthening lax ligaments, has found increased acceptance in recent years. Prolotherapy involves the injection of the irritant solutions into the weakened or stretched ligaments which are a source of chronic pain. This induces an inflammatory response which mimics the normal repair sequence. Various musculoskeletal disorders of lower extremities such as degenerative arthrtitis, ligament and tendon injuries can be treated with prolotherapy. Prolotherapy is a very good, powerful nonsurgical conservative treatment in various musculoskeletal disorders. Ultrasound exam is very useful to find and confirm the exact location of disorders and check the progress in prolotherapy practices.

To describe the background, mechanism, clinical results and complications of prolotheapy based on the literature review. Prolotherapy is a minimally invasive injection-based treatment of chronic musculoskeletal pain, including ligament and joint laxity. The mechanism of this injection-based technique is to initiate a local inflammatory response with resultant tissue healing. The used proliferants are classified by bio-mechanism to act in three different ways as osmotic, irritants, and chemotatics. The most commonly used proliferant is hyperosmolar (10~25%) dextrose to act by osmotic rupture of cells. High resolution ultrasound imaging of musculoskeletal structure provide a more accurate diagnosis. Also ultrasound-guided intervention provides a more high efficacy and low rate of complications. The most common complication is local pain at the injected site, that is self-limited and good responsive to anti-inflammatory agents. Other complications are rare. It is reported that prolotherapy appears safe when performed by an experienced clinician. Prolotherapy has grown in popularity and has received significant recent attention. However there are limited evidence-based data supporting the indication and efficacy of prolotherapy in the treatment of chronic musculoskeletal pain or soft tissue injuries. Future studies are necessary to determine whether prolotherapy can play an independent and definitive role in a treatment for chronic musculoskeletal pain.

Musculoskeletal sonography is rapidly developing due to the merits such as relatively low cost and possibility of dynamic study. Sonography can be helpful and easily introduced for the diagnosis of the foot and ankle disease. This review tried to clarify the cause and sonographic diagnosis of common foot and ankle diseases.

Ultrasound is a first line examination of the knee and useful diagnostic tool in assessing the various knee lesions. The advantages of ultrasound are that it is non-invasive, easily available at bed side, cheap, well accepted by patients, and that it has technical benefits including dynamic evaluation. Its limitations include reliability, which is largely operator dependent and its inability to evaluate deep structures. Technical guidelines of the ultrasound released by European Society of MusculoSkeletal Radiology (ESSR) and ultrasonographic findings of various knee lesions are described.

Rotator cuff tears are a leading cause of shoulder pain in adults. Due to the increase in social activities, the number of patients complaining of shoulder pain is increasing, and interest in shoulder diseases is also increasing. With the development of ultrasound equipment, the sensitivity and specificity of diagnosis are high, and it is used to diagnose rotator cuff tears in musculoskeletal disease. Ultrasound is recognized as a complementary method to MRI examination in rotator cuff tears. Therefore, this study aimed to find out the diagnostic usefulness of ultrasound and MRI examinations in the diagnosis of shoulder rotator cuff tears.A retrospective analysis was performed on 262 patients who were diagnosed with final rotator cuff damage by arthroscopy after completing ultrasound and MRI examinations. Sensitivity, feature, positive predictive value, image predictive value, and touch were disassembled for the test results. In addition, the degree of clavicular tear was scored and recorded in 5 stages. Ultrasound examination was similar to MRI examination results for both full-thickness and partial tears, and there was no statistically significant difference. Partial tear test results showed higher positive predictive value and accuracy than MRI test. In conclusion, ultrasound can be fully utilized as a screening test for rotator cuff disease, and it is thought that it will be selected and used clinically according to the patient's constitution and situation.

This study was to investigate the prevalence rate of musculoskeletal disorders in relation to general characteristic factors, living environment factors, and work environment factors for sonographer's. For the response questions, the guidelines for musculoskeletal burden work were used. For statistical analysis, SPSS 26.0 version was used. For the common body parts of the sonographer's who responded, the prevalence was investigated by dividing the group into a group with high pain or discomfort and a group with low pain or discomfort according to the degree to which they experienced symptoms during the past 12 months. Multiple logistic regression analysis was used to determine the variance inflation factor(VIF), odds ratio (OR) and corresponding 95% confidence interval (CI). A p-value of <0.05 was considered statistically significant. As a result, housework hours, examination history, regular physical activity, number of patient examinations per day, and sitting posture were investigated as variables for rate musculoskeletal disorders. The sonographer's occupational group was found to have a high prevalence rate of musculoskeletal disorders like various other occupational groups. Based on the results of this study, it is judged that musculoskeletal disorders can be reduced by recognizing musculoskeletal disorders and improving work environment factors.
