The ultrasound can be used primarily to guide exact needle placement for aspirations of fluids, injections of steroid, and biopsies in musculoskeletal field. Recently, ultrasound-guided intervention is widely used because of several advantages such as real-time performance, relatively inexpensiveness, and getting multiple images without additional radiations. However, the modality is operator dependent and requires detailed knowledge of the relevant anatomy and there have been also reported serious complications related to the procedure. So, authors will discuss about the basic techniques, principles and cautions for the use of ultrasound-guided intervention in musculoskeletal field.

Nowadays shoulder ultrasound is commonly used in the assessment of shoulder diseases and is as accurate as magnetic resonance imaging in the detection of several pathologies. Operator dependence is the main disadvantage of shoulder ultrasound. After adhering to a strict examination protocol, good knowledge of normal anatomy and pathologic processes and an awareness of common pitfalls, it can be used as a focused examination providing rapid, real-time diagnosis, and treatment by ultrasound-guided interventions in desired clinical situations. Also shoulder ultrasound can help the surgeon decide whether treatment will be surgical or nonsurgical. If arthroscopy is planned, sonographic findings help to counsel patients regarding surgical and functional outcomes. If a nonsurgical approach is indicated, ultrasound can be used to follow patients. This review article presents the examination techniques, the normal sonographic appearances and the main pathologic conditions found in shoulder ultrasound. And also addresses a simplified approach to scanning and ultrasound-guided intervention. Knowledge of optimal techniques, normal anatomy, dynamic maneuvers, and pathologic conditions is essential for optimal performance and interpretation of images.

There are several kinds of regional nerve blockades, such as interscalene brachial plexus block, C5 root block, suprascapular nerve block, and axillary nerve block, which can be applied for anesthesia and postoperative pain control after shoulder surgeries. These regional nerve blockades have shown good results, but high failure rate and serious complications, such as phrenic nerve palsy, pneumothorax, and nerve injury, still remain. Ultrasound-guided intervention can increase the success rate of nerve blockades and reduce complications. We described the method of ultrasound-guided intervention for the regional nerve blockades around shoulder.

The use of ultrasonography has recently been increasing in musculoskeletal diagnosis or intervention treatment. Ultrasound guided procedure offers a reliable alternative to fluoroscopy or computed tomography for lumbar medial branch block, facet joint block and peripheral nerves of lower extremity. Further, there is no exposure to radiation and additional equipment necessary for the protection against radiation is required. And ultrasound guided procedure needs smaller space than fluoroscopy guided procedure with real time images in the outpatient department. This article reviews ultrasound guided procedure at lumbar vertebra and peripheral nerves of lower extremity.

Ultrasound (US) can depict of various anatomical structures, such as muscles, tendons, ligaments, nerve roots, and vessels, around the neck. The usage of US around the neck is increasing due to its quick and easy application for guided injection for nerves, tendons, and joints. This article elaborates the degenerative diseases causing neck pain, sonoanatomy, and the use of US for diagnosis and intervention; for example, small nerves around the neck, cervical root, stellate ganglion, medial branches, greater occipital nerve (GON), and third occipital nerve (TON). The aim of this review article is to lead readers to understand the anatomy around the neck and structural relations, and to get to know about several US-guided intervention of the neck.

Objective: Many studies have demonstrated that hydrosalpinx has a detrimental effect on the outcome of IVF. Treating hydrosalpinges prior to the IVF procedure in women with hydrosalpinges is thought to improve the likelihood of successful IVF outcome. Vaginal ultrasound-guided aspiration of hydrosalpinx fluid (HSF) with injection of the sclerosing agent in situ might be simpler than invasive procedures like salpingectomy. Therefore, we carried out a retrospective study on the effects of ultrasound-guided HSF aspiration and injection of the sclerosing agent of ultrasonically diagnosed hydrosalpinx on IVF outcome. Methods: In our retrospective study, 97 tubal factor infertile female patients that underwent IVF treatment between January 2005 and December 2012 at the Reproductive Medicine Center of CHA Hospital were divided into two study groups. Fifty-six patients underwent interventional ultrasound sclerotherapy (group 1), and the remaining 41 patients received laparoscopic salpingectomy (group 2) before IVF. We compared the IVF outcomes of the two groups. Results: The results showed that ultrasound-guided HSF aspiration and sclerotherapy have IVF outcomes comparable to laparoscopic salpingectomy. Conclusion: Interventional ultrasound guided sclerotherapy before IVF is an effective and less invasive prophylactic intervention alternative to salpingectomy with hydrosalpinx.

Background: Recently, ultrasound has been commonly used. Ultrasound-guided interscalene brachial plexus block (IBPB) by posterior approach is more commonly used because anterior approach has been reported to have the risk of phrenic nerve injury. However, posterior approach also has the risk of causing nerve injury because there are risks of encountering dorsal scapular nerve (DSN) and long thoracic nerve (LTN). Therefore, the aim of this study was to evaluate the risk of encountering DSN and LTN during ultrasound-guided IBPB by posterior approach. Methods: A total of 70 patients who were scheduled for shoulder surgery were enrolled in this study. After deciding insertion site with ultrasound, awake ultrasound-guided IBPB with nerve stimulator by posterior approach was performed. Incidence of muscle twitches (rhomboids, levator scapulae, and serratus anterior muscles) and current intensity immediately before muscle twitches disappeared were recorded. Results: Of the total 70 cases, DSN was encountered in 44 cases (62.8%) and LTN was encountered in 15 cases (21.4%). Both nerves were encountered in 10 cases (14.3%). Neither was encountered in 21 cases (30.4%). The average current measured immediately before the disappearance of muscle twitches was 0.44 mA and 0.50 mA at DSN and LTN, respectively. Conclusions: Physicians should be cautious on the risk of injury related to the anatomical structures of nerves, including DSN and LTN, during ultrasound-guided IBPB by posterior approach. Nerve stimulator could be another option for a safer intervention. Moreover, if there is a motor response, it is recommended to select another way to secure better safety.

Musculoskeletal ultrasound has evolved as the essential tool to diagnose and guide intervention procedures in people with neuromusculoskeletal conditions. Image optimization and understanding device operations are core components for ultrasound guided intervention procedure training. All ultrasound machines share the common operative features and there are various buttons for the features in the device control panel. Ultrasound "knobology" refers to the thorough understanding of imaging optimization. This review addressed basic information for the transducers, depth setting, gain and focus control, different modes focusing on brightness and doppler modes.

Ultrasound has emerged to become a commonly used modality in the performance of chronic pain interventions. It allows direct visualization of tissue structure while allowing real time guidance of needle placement and medication administration. Ultrasound is a relatively affordable imaging tool and does not subject the practitioner or patient to radiation exposure. This review focuses on the anatomy and sonoanatomy of peripheral non-axial structures commonly involved in chronic pain conditions including the stellate ganglion, suprascapular, ilioinguinal, iliohypogastric, genitofemoral and lateral femoral cutaneous nerves. Additionally, the review discusses ultrasound guided intervention techniques applicable to these structures.
