Ultrasonography in Osteoarthritis / 대한내과학회지

Ultrasonography (US) is a valuable imaging modality used to assess joint and periarticular abnormalities in patients with osteoarthritis (OA). US can detect articular cartilage damage, bony changes, joint effusion, synovitis, and adjacent soft tissue lesions. In addition, US facilitates the monitoring of disease progression and effects of treatments. US is a safe and accessible bedside procedure that can improve diagnosis and management of patients. The objective of this article was to describe the clinical applications of US for patients with OA.

Bony Spur Formation Following Lateral Condyle Fracture of the Humerus in Children / 대한정형외과학회잡지

PURPOSE: The purpose of this study was to determine the incidence, location and contributing factors of the bony spur formation following lateral condyle fracture of the humerus in children. MATERIALS AND METHODS: Sixty four lateral condyle fractures of the humerus followed up until bony union were retrospectively reviewed in the type of fracture, accuracy of the reduction, and the formation, size, location of the bony spur on serial radiographs. Treatment method was recorded. RESULTS: In all children but one case showed bony spur formation in plain radiograph, be it large or small. The size of bony spur was not correlated with the extent of displacement nor treatment methods, but significantly related with the accuracy of reduction. In long term follow-up, the bony spurs decreased in size. CONCLUSION: Accuracy of reduction determinates the size of bony spur following lateral condyle fracture of the humerus in children. In order to prevent or minimize the bony spur formation, accurate reduction is desirable. Even if bony spur formation was present in early healing stage, it can be expected to decrease in size.

Anterior impingement of the Ankle Treated by Arthroscopic Removal of bony Spur / 대한정형외과학회잡지

From September 1992 to April 1994, we reviewed 7 patients after arthroscopic surgery for anterior impingement in the ankle, who complained ankle pain and limitation of motion. All patients were mem and main symptoms were severe pain at full dorsiflexion of ankle and limitation of motion. Bony spur was located on the anterior aspect of tibia, and it was possible to resect the tibial bony spur arthroscopically without distraction devices. Mean operation time was 55 minutes. Pain, swelling and limitation of motion were much improved. There was no postoperative complication. Arthroscopic resection of the anterior tibial bony spur is an effective treatment for anterior impingement in the ankle.

Mechanism of Formation of the Posterior Bony Spur of the Lumbar Spines in Young Adults

The bony spur formation without degenerative change in the lumbar spines in the young age group is quite interesting and is not uncommon. This bony spur is different from the degenerative spur in the old age group in shape and mechanism of formation. The authors analyzed 25 patients below 29 years old with such posterior lumbar bony spur. We concluded that posterioly located Schmorl's node is main cause of the bony pour in youn age group at lumbar region.
