Synovial Hemangioma Mimicking a Meniscal Cyst of the Knee / 대한정형외과학회잡지

Synovial hemangioma is a vascular malformation that usually involves the knee. This paper presents the diagnostic ultrasound findings of a synovial hemangioma that could be mistaken for a medial meniscus cyst in a 37-year-old man and report the clinical result of the meniscal repair after an open excision.

Tibial Schwannoma Mimicking a Popliteal Cyst / 대한정형외과학회잡지

Schwannoma is the most common benign tumor of peripheral nerves and usually appears on the trunk, head and neck, or extremities. A mass arising at popliteal fossa can be misdiagnosed as a popliteal cyst. We report on a rare case of a popliteal schwannoma mimicking a popliteal cyst in a 39-year-old female who showed a clinical presentation similar to that of a popliteal cyst. Diagnosis was delayed until ultrasonographic evaluation was performed due to its anatomical location, the same as that of a popliteal cyst. We describe the clinical significance and ultrasonographic findings of the schwannoma for initial differential diagnosis from a popliteal cyst.

Treatment of Scapula Fractures of the Inferior Angle Causing Pseudowinging Scapula / 대한정형외과학회잡지

Nonoperative treatment of scapular body fractures has shown good clinical results. Although scapula fractures of the inferior angle, particularly with oblique lines from the medial proximal to lateral distally, are very rare, we believe that such a fracture pattern would be regarded as an avulsion fracture of the serratus anterior muscle requiring surgery. We have experienced three cases demonstrating pseudowinging of the scapula due to displacement of the inferior angle fracture of the scapula. Surgical repair or plating showed satisfactory clinical results. Through these cases, we describe the cause of winging scapula and the problems resulting from an avulsion fracture of the serratus anterior muscle with a review of the relevant literature and explain the reason that an operation is needed for this fracture pattern.

Sarcoidosis Presenting as Knee Pain / 대한정형외과학회잡지

Sarcoidosis is a multisystem granulomatous disease of unknown etiology with variable manifestations, which may affect virtually any organ. Muscular sarcoidosis is a rare entity, and among this group of muscular lesions, the mass-like muscular sarcoidosis type is extremely rare. We reported a muscular sarcoidosis case that presented with right knee pain and described the clinical results with an added review of the relevant literature.

Partial Rupture of Semitendinosus Muscle at Satba (Thigh Band) Wearing Area in a Ssireum Athlete / 대한정형외과학회잡지

High load is concentrated on Satba wearing area of Ssireum athletes during the tournament. Muscular injuries in this area may seriously affect the athletic performance. We report a case of a 21-year-old Ssireum athlete who was experiencing pain in his left thigh (Satba wearing area) during a tournament due to the migrating mass effect of a partial ruptured semitendinosus muscle occurred approximately 6 months before. Herein is described the clinical results after surgical intervention with an added review of the relevant literature.

Distal Radius Fractures Using Acu-Loc Volar Plate

OBJECTIVE: We determined the radiographic outcome of distal radius fractures with Acu-loc volar plate. METHODS: Forty-one patients were recruited between August 2009 and September 2010. There were 10 males and 31 females, with a mean age 61.2. Fractures were radiologically classification the Frykman. Fifteen fractures were group 8, eight were group 7, ten were group 6, four were group 5 and four were group 3. Distal part of the fractures was dorsally inclined in 37 wrists and inclined to volar side in four wrists. Lateral and anteroposterior radiographs taken after operated day, the fracture were compared with radiographs of the injured wrist and the differences in palmar tilt, ulnar variance; radial height; radial shift and radial inclination were measured. RESULTS: There was significant improvement in the measurements of radial height, radial inclination, volar tilt, ulnar variance and radial shift postoperatively. The radial height improved from an average of 8.5 mm (range, 3 to 15 mm) to 11.0 mm (range, 8 to 15 mm), the radial inclination improved from an average of 21.5 degree (range, 10 to 40 degree) to 28.1 degree (range, 19 to 44 degree), the palma tilt improved from an average of 12.9 degree (range, 6 to 22 degree) to 17.2 degree (range, 7 to 27 degree), the ulnar variance improved from an average of -2.3 mm (range, -6 to 4 mm) to 1 mm (range, -3 to 7 mm) and the radial shift improved from an average of 18.7 mm (range, 15 to 26 mm) to 17.3 mm (range, 12 to 21 mm). CONCLUSION: Acu-loc volar plate is a safe and effective device.

Arthroscopic Resection of the Chondroma in the Supraspinatus of the Shoulder / 대한정형외과학회잡지

Soft-tissue chondroma is rare a benign soft-tissue tumor that occurs mainly in hands and feet. There have been no reports of a chondroma in the supraspinatus tendon. We describe the clinical, histological and radiological features of the intratendinous chondroma of the supraspinatus occurring in a 30-year-old man who was managed arthroscopically and a review of the relevant literature review.

Multiple Rice Bodies in Subacromial Space: A Case Report

Multiple rice bodies are a rare disorder that is most commonly observed in chronic rheumatoid arthritis patients and as a complication of chronic inflammation in the bursa. However, it can occur in the absence of an underlying systemic disorder. Although it resembles synovial chondromatosis clinically and on imaging, the condition can be discriminated by an analysis of the radiographic and MR appearances. We encountered a case of multiple rice body formation with subacromial bursitis on the shoulder of a 37-year old man suffering from pain and motion limitation. The patient was treated by arthroscopic removal of the multiple rice bodies and a subacromial bursectomy. We present this case with a review of the relevant literature.
