Tenosynovitis of the extremities is not uncommon but its diagnosis is not easy owing to its non-specific clinical manifestation. Thus it was beyond the field of imaging diagnosis so far. Recently the development of high resolution ultrasonogram has aided preoperative imaging diagnosis of tenosynovitis. The authors performed a retrospective review of 27 patients who had ultrasonography due to tendon pathology(including 18 tenosynovites) by oserving sonographic finding and evaluation the diagnostic value of each finding. The overall diagnostic accuracy was 81.1% and common sonographic findings were focal swelling of the tendon. well-defined margin of the lesion, preserved fibrillar pattern, echo change of the lesion site and fluid collection. Above al,. fluid collection was the only statistically significant criterion for diagnosis of tenosynovitis (p<0.05). But its sensitivity was as low as 50%. In conclusion the ultrasonography is useful in diagnosis of tenosynovitis and fluid collection is of diagnostic value, but the differentiation between nodular tenosynovitis without fluid collection and other benign tumor is still beyond the scope of ultrasonographic diagnosis.

OBJECTIVE: To find the optimal needle insertion site for needle electromyography of the pronator teres (PT) muscle among commonly used sites. METHODS: Fifty forearms of 25 healthy subjects were evaluated. Four expected needle insertion points were designated as follows. Point 0 was positioned at the midpoint between the medial epicondyle and medial border of biceps tendon in the elbow crease. Points 1, 2, and 3 were located 2 cm, 3.5 cm and 5 cm distal to point 0, respectively. We assumed that the thickness of PT and the distances between a vertical line from each point to the medial margin of the PT were significant parameters for finding the optimal site. Thus, we measured these parameters through ultrasonographic examination. RESULTS: In men, the PT was thickest at point 2, and in women, at point 1. The distance between the expected needle insertion line and medial margin of PT was longest at point 1 in both men and women, and was statistically significant compared to points 2 and 3. Both men and women had neurovascular bundles located lateral to the expected needle insertion line. CONCLUSION: The most appropriate and safe needle electromyographic insertional site for the PT is 2-3.5 cm distal to the mid-point between the biceps tendon and medial epicondyle in the elbow crease and the needle should be inserted upward and medial.

Avulsion injury of the flexor digitorum profundus (FDP) tendon from the distal phalanx is considered as a rare injury. We report a patient who sustained a FDP tendon rupture insertion on her fifth finger as a result of a closed, hyperextension with no accompanying laceration or predisposing pathologic condition. Preoperative ultrasonography showed complete rupture of FDP and the gap between the tendon ends. According to the classification by Leddy and Pacter, this case is type II. The reconstruction of flexor tendon using pull-out suture and tie-over button. We are reporting a case with brief review of literatures.

PURPOSE: The purpose of this study is to assess the sonographic findings of Osgood-Schlatter disease with correlation to radiographic findings and to determine value of sonography in the diagnosis of Osgood-Schlatter disease. MATERIALS AND METHODS: The population consist of 22 cases of Osgood-Schlatter disease and 15 healthy subjects of the same age range for comparison. The sonographic study was carried out with real time units equipped with linear probe of 7 MHz frequency. Radiography and sonography were done in all cases and follow-up sonography was performed in 10 cases. RESULTS: The sonographic features of the Osgood-Schlatter disease were swelling of cartilage over the anterior tibial tuberosity ossification center in 16 cases, fragmentation and/or irregularities of the ossification center of the anterior tibial tuberosity in 14 cases, localized thickening of the pateliar tendon in 14 cases, ossicles in the thickened pateliar tendon in 3 cases, and distension of the infrapatellar bursa in 2 cases. Fifteen of 22 cases of Osgood-Schlatter disease had abnormal findings on radiographs and sonograms. Out of 7 cases which had normal radiograph and abnormal findings on sonogram, 6 cases showed pateliar tendon thickening, cartilage swelling, and/or distended infrapatellar bursa and one case showed fragmentation of anterior tibial tuberosity on sonogram. CONCLUSION: Sonographic evaluation of Osgood-Schlatter disease provided a clear picture about pathologic changes in the superficial soft tissues and in the cartilage and also yielded the same diagnostic information on bony change as radiography Sonography is a reliable and useful method for the evaluation of young patients with clinically suspected Osgood-Schlatter disease.

The ultrasonography (US) is an important modality in evaluating shoulder disease. It is accurate in diagnosing the various shoulder diseases including tendinosis, calcific tendinitis, and subacromial bursitis as well as rotator cuff tears. This article presents a pictorial review of US anatomy of the shoulder, the technical aspects of shoulder US, major types of shoulder pathology, and interventional procedure under US guidance.

A 16-year-old female weight-lifter with average records of 70 kg for the snatch event and 90 kg for the clean and jerk event suffered chronic ulnar collateral ligament injury, and underwent ulnar collateral ligament reconstruction. An ultrasonographic evaluation was performed at six weeks, three months, six months, nine months, and one year after the operation. The horizontal and vertical distances measured during the initial ultrasonographic examination as well as at six weeks, three months, six months, nine months, and one year after the operation were 8.4 mm, 2.0 mm, 2.6 mm, 2.8 mm, 2.7 mm, 2.7 mm, and -1.2 mm, 2.4 mm, 1.0 mm, 0.0 mm, 0.0 mm, 0.0 mm, respectively. The lifting records at one year after the operation were 65 kg for the snatch event and 90 kg for the clean and jerk event. The ultrasonographic method of serial examination was useful for evaluation of the rehabilitation program and for deciding on the time to return to competition.
