  • After the introduction of ultrasound enabling a detailed view of both neonatal hip instability and morphology, two different streams have developed: one arguing that neonatal hip instability is the major pathology warranting treatment, the other including acetabular dysplasia as an important feature. Graf's method including the acetabular dysplasia led to higher treatment and follow-up rate than that based upon neonatal hip instability only. Recent report suggested that improved examination techniques and a better understanding of the findings have enabled a more tailored approach, and no differences in treatment rates exist due to different ultrasound techniques. I'd like to emphasize that enough experiences and the understanding enabling standardized examination and high repeatbility is more important than the choice of different techniques. Here the mothods and meanings of different techniques of ultrasound and its usefulness in the diagnosis and treatment of DDH is discussed.

  • In this study, we evaluated the heating characteristics of single sonication and superposed two low-intensity ultrasonic sonication. Compare the results, the superposed sonication was showed a superior thermal effect than single sonication. And the maximum temperature was increased as 120-150%. The starting time of temperature rising has been shortened in superposed sonication. In addition, the time up to the maximum temperature has been shortened, too. In generally, as the ultrasonic intensity is higher, the more surface damage is occurred. However, in the case of superposed sonication, the same thermal effect had be confirmed without surface damage. Through the results of the study, we thought that the superposed sonication will be able to reduce the intensity of the ultrasonic treatment. And, by using the low-intensity, the more safe and more effect therapy will be possible in therapeutic ultrasound application.

  • Clonorchiasis is an important parasitic disease of humans in Korea. The present study intended to compare sonographic findings with histopathological changes in experimental clonorchiasis. Eighteen New Zealand white rabbits were infected with metacercariae of Cknorchis sinensis, and examined 4, 10, and 22 weeks post-infection (PI). Four infected rabbits were treated with praziquantel 10 weeks PI and were examined 12 weeks after treatment. Sonography revealed mild to severe dilatation of the intrahepatic ducts (IHDD) and slightly increased periductal echoes in 12 out of 14 rabbits at 4 weeks PI, and all of the animals after 10 and 22 weeks PI and 12 weeks after treatment. The histopathological lesions were duct dilatation, mucosal hyperplasia, and periductal fibrosis, which progressed from 4 weeks to 22 weeks PI and even in treated rabbits. The dilated intrahepatic ducts over 1 mm diameter were detected by sonography. The present results indicate that sonographic findings are well correlated with histopathological lesions in rabbit clonorchiasis except for early phase of light burden of infection. The sonography has a limitation in discriminating residual sequelae of the ducts after praziquantel treatment.

  • Purpose: The purpose of this study is to evaluate the clinical usefulness of ultrasound in treatment of patella fracture. Material and Methods: Twenty cases of twenty patients with patella fracture radiographically from March, 2006 to September, 2009 were involved in this study, there were 8 males and 12 females, there were 13 right knees, 7 left knees, the average age was 43 years (range, 14~72 years). We decided the methods of treatment by using the ultrasound in conjunction with Drayer's test that examining the intactness of patella retinaculum. There were 10 transverse, 8 vertical and 2 comminuted fractures, we examined the patella retinaculum by using the ultrasound and performed Drayer's test. Results: In 12 cases of intact retinaculum, Drayer's test was negative and we allowed patients ambulation without surgical fixation especially. In 4 cases of completely ruptured retinaculum, Drayer's test was positive and we treated the patella fractures by the use of ORIF (open reduction and internal fixation) method, in 2 cases of partially ruptured retinaculum, Drayer's test was negative but displacement of fractures were more than 2 mm, we treated the patella fractures by the use of CRIF (closed reduction and internal fixation) method and obtained clinically satisfactory results. Conclusion: In conjunction with radiographs and Drayer's test, an ultrasound would be one of the useful diagnostic modality for determining treatment method of the patella fracture.

  • Although surgical drainage has been performed in most reported cases of psoas abscess, ultrasonographically guided percutaneous drainage could be effective treatment for psoas abscess. However, utility of percutaneous drainge under ultrasound is less well established. We present a patient in whom fungal psoas abscess was managed by ultrasonographically guided percutaneous aspiration with literature review. Drainage was done by needle aspiration under ultrasound guidance and there was no procedural complication. After aspiration, Candida Albicans was found as a causing organism responsible for abscess and abscess could be successfully treated by repeated aspiration and appropriate antifungal therapy.

  • 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.

  • Study Design: Literature review. Objective: Ultrasound-guided injections are a common clinical treatment for lower lumbosacral pain that are usually performed before surgical treatment if conservative treatment fails. The aim of this article was to review ultrasound-guided injections in the lumbar and sacral spine. Summary of Literature Review: Ultrasound-guided injections, unlike conventional interventions using computed tomography or C-arm fluoroscopy, can be performed under simultaneous observation of muscles, ligaments, vessels, and nerves. Additionally, they have no radiation exposure and do not require a large space for the installation of equipment, so they are increasingly selected as an alternative method. Materials and Methods: We searched for and reviewed studies related to the use of ultrasound-guided injections in the lumbar and sacral spine. Results: In order to perform accurate ultrasound-guided injections, it is necessary to understand the patient's posture during the intervention, the relevant anatomy, and normal and abnormal ultrasonographic findings. Facet joint intra-articular injections, medial branch block, epidural block, selective nerve root block, and sacroiliac joint injections can be effectively performed under ultrasound guidance. Conclusions: Ultrasound-guided injections in the lumbar and sacral spine are an efficient method for treating lumbosacral pain.

  • We experienced three cases with chronic shoulder pain due to a knot impingement after arthroscopic rotator cuff tear repair and treated with arthroscopic revision surgery. Ultrasonography is commonly used for an imaging scan and an useful diagnostic tool to follow up after rotator cuff repair recently. We also could diagnose three cases with the knot impingement using ultrasonography obviously. And we report these cases with a review of current literature.
