There are many wrist and hand diseases in which ultrasound can help in the diagnosis and treatment. Because many small structures are located, identifying anatomical locations and pathways is especially important. In De Quervain's syndrome, it is necessary to find tendon lesions located in the first compartment of the wrist. If injection therapy is required, administer the regimen accurately within the tendon sheath through ultrasound. In carpal tunnel syndrome, there are several methods to diagnose a disease by measuring cross-sectional area of the median nerve. Ultrasound has the advantage of administering injection therapy without damaging the nerve. Intersection syndrome can be diagnosed by observing swelling and hypoechoic appearances at the point where the tendons of the first compartment cross over the second compartment of the wrist. Ultrasound-guided injection is also safe and efficient. If there is a trigger finger lesion, the most representative findings is to observe a nodular hypoechoic thickening of the involved A1 pulley. When injection therapy is performed, it is effective to administer medication between pulley and flexor tendons as much as possible to reduce pressure on the attached structures.

Chronic postoperative inguinal pain (CPIP) is a major complication after inguinal herniorrhaphy. We report the treatment of CPIP using ultrasonography-combined with nerve stimulator for injection of the genitofemoral nerve (GFN). A 59-year-old man underwent laparoscopic herniorrhaphy and presented with numbness from the inguinal region to the scrotum after operation. In the pain clinic, ultrasonography-guided GFN block and pharmacological treatments had little effect. Six month after operation, patient was referred to the Department of Physical Medicine and Rehabilitation, and ultrasonography-combined with nerve stimulator for GFN injection underwent to enhance the accuracy of neural approach. The induction of scrotal contraction and paresthesia on the GFN distribution was monitored by nerve stimulator and local anesthetic was injected. After the block, pain relief lasted for 6 months without analgesic use. Ultrasonography-combined with nerve stimulator is an effective approach to treat CPIP as it enhances precise localization and injection of small peripheral nerve like GFN.

Nationally, flatfish vaccination has been performed manually, and is a laborious and time-consuming procedure with low accuracy. The handling requirement also makes it prone to contamination. With a view to eliminating these drawbacks, we designed an automatic vaccine system in which the injection is delivered by a Cartesian coordinate robot guided by a vision system. The automatic vaccine injection system is driven by an injection site location algorithm that uses a template-matching technique. The proposed algorithm was designed to derive the time and possible angles of injection by comparing a search area with a template. The algorithm is able to vaccinate various sizes of flatfish, even when they are loaded at different angles. We validated the performance of the proposed algorithm by analyzing the injection error under randomly generated loading angles. The proposed algorithm allowed an injection rate of 2000 per hour on average. Vaccination of flatfish with a body length of up to 500mm was possible, even when the orientation of the fish was random. The injection errors in various sizes of flatfish were very small, ranging from 0 to 0.6mm.

Objective: To find that the patients who conducted home self-exercise in conjunction with intra-articular corticosteroid injection will have better improvement in subacromial subdeltoid (SASD) bursitis symptoms than those who received only an injection. Method: A prospective, nonrandomized, comparison study was conducted in outpatient rehabilitation clinic in a tertiary university hospital. Patients diagnosed with SASD bursitis with physical examination and ultrasound evaluation were included and received ultrasound guided injection (UGI). Patients were divided into two groups according to the compliance of self-exercise: UGI-exercise group and UGI only group. Visual analog scale (VAS) was checked before, at 3 weeks, 3 months, and 6 months after the UGI. A patient's global impression of change (PGIC) survey was made at 3 months after the UGI. Results: A total of 82 patients with SASD bursitis were included. At 3 weeks after the injection, the mean VAS for the UGI-exercise group was 2.6 ± 1.7 and for UGI only group was 1.9 ± 1.3 (p=0.030). At 3 months after the injection, the mean VAS for the UGI-exercise group was 4.0 ± 1.3 and for UGI only group was 5.4 ± 1.4 (p<0.001). Conclusion: We concluded that home-based self-exercise of the shoulder provides an additional benefit for pain alleviation possibly with prolonging the effect of injection in SASD bursitis.

Background: The subacromial (SA) space is a commonly used injection site for treatment of impingement syndrome. For shoulder stiffness, glenohumeral (GH) injections are commonly performed. However, in cases of impingement syndrome with mild shoulder stiffness, the optimal site of steroid injection has yet to be identified. Methods: This prospective, randomized study compared the short-term outcomes of ultrasound-guided GH and SA steroid injections in patients who were diagnosed with impingement syndrome and mild stiffness. Each group comprised 24 patients who received either a GH or SA injection of 40 mg of triamcinolone. Range of motion and clinical scores were assessed before and 3, 7, and 13 weeks after the injection. Results: GH and SA injections significantly improved the range of motion and clinical scores after 13 weeks of follow-up. Notably, targeting the GH joint resulted in an earlier gain of forward elevation, external rotation, and internal rotation in 3 weeks (P<0.001, P=0.012, and P=0.002, respectively) and of internal rotation and a Constant-Murley score in 7 weeks (P<0.001 and P=0.046). Subsequent measurements were similar between the groups and showed a steady improvement in all ranges of motion and clinical scores. Conclusions: GH injections may be more favorable than SA injections for treatment of impingement syndrome with mild stiffness, especially in improving the range of motion in the early period. However, the procedures showed similar outcomes after 3 months. Level of evidence: I.

The objective of this study was to produce calves by transfer of embryos derived from slaughter house(SHD) and ultrasound-guided ovum pick-up (OPU). At 60 hrs after injection of 400 mg FSH dissolved in 25% polyvinylpyrrolidone(PVP) by single dose, ultrasound-guided follicular oocyte aspiration was ferformed. Day-7 and day-8 blastocysts produced by in vitro maturation (IVM), fertilization (IVF) and culture(IVC) of the oocytes derived from SHD and OPU were nonsurgically transferred into recipients. The results obtained were as follows. The cleavage rate and the development rate to blastocysts were not significantly (P<0.05) different between the oocytes obtained by SHD (72.9% vs. 34.1%) and OPU (75.9% vs. 38.4%). The oocyte recovery rate from the number of follicles by ultrasound-guided aspiration were not significantly (P<0.05) different between Holstein (61.7%) and Hanwoo (60.1%), but the rate of oocytes useful for IVF was significantly (P<0.05) higher in Hanwoo (69.3%) than Holstein (59.6%). The cleavage rate and the development rate to blastocysts was not significantly (P<0.05) different between Holstein (74.9% vs. 39.2%) and recipients on day 8 of estrus cycle resulted in 13 pregnancies (34.2%). One of them was sacrificed during gestation period due to mastitis and another was aborted spontaneous. The resulting 14 calves were morphologically normal at birth. Seventy eight fresh OPU-IVF embryos were transferred into 21 recipients on day 8 of estrus cycles, resulting in pregnancy of 12 recipients (41.4%). Two of them were sacrificed during gestation period due to mastitis and the other two were aborted. Nevertheless, the 11 OPU-calves have been born normally.
