Limbic bone or persistant epiphysis seen roentgenographically on the anterosuperior aspects of the vertebral bodies represents another form of discal extrusion, seperating a small fragment of bone from the body of the involved vertebra. Lindblom, in 1951, demonstrated the pathophysiology with discography. Anterior herniation of the nucleus pulposus was also revealed by discography by Cloword and Buzaid in 1952. The authors reviewed 3 cases of limbic bone of the vertebrae.

Chondroblastoma is an uncommon primary benign bone tumor that usually arises in the epiphyses of the long bones. Chondroblastoma of temporal bone is extremely rare. Its biological nature is often benign but is sometimes aggressive because of the local invasion. Recently, the authors have experienced two cases of chondroblastoma of temporal bone which were completely excised. We report these cases of chondroblastoma of the temporal bone with a review of literature.

Complete fractures of radial neck or proximal radial epiphysis with 90° displacement are very rare, and only several cases were reported in the literatures. We have experienced 2 cases of radial neck fracture with 90° posterior displacement and one case with anterior displacement. All of them were treated operatively. We followed up these 3 cases more than 15 months and report the results with review of literatures.

Chondroblastoma is an uncommon, benign, cartilaginous neoplasm originating in an epiphysis or apophysis of a long tubular bone. The rib is an unusual site for chondroblastoma. The authors describe a case of chondroblastoma of the rib and present a brief review of the literature.

Thiemann's disease is a form of idiopathic avascular necrosis of the immature epiphyses of the phalanges of the fingers and toes. Few cases of Thiemann's disease have been reported because the disease is rare and difficult to diagnose. To the best of our knowledge, magnetic resonance imaging (MRI) findings of Thiemann's disease have not been reported. Here, we report a case of Thiemann's disease diagnosed by typical clinical symptoms and characteristic MRI findings before radiologic bony abnormalities were apparent.

The triplane fracture has been described as a fracture of the distal tibial epiphysis occurring across three planes-sagittal, transverse and coronal. The characteristic pattern of fusion of distal tibial epiphysis explains the special configuration of the fragments in the triplane fracture. According to Dias.Tachdjian classification, triplane fracture is classified two part fracture, three part fracture, four part fracture and two part fracture with extension to the medial malleolus. Among four types, two part triplane fracture with extension to the medial malleolus is a relatively rare injury and generally is not treated by closed reduction. Such fractures should have an anatomic reduction and adequate fixation to restore the joint congruity and obtain an anatomic reduction of the growth plate to prevent a future growth deformity. This is usually best accomplished with an open reduction and screw fixation or k-wire fixation. We experienced two part triplane fracture with extension to medial malleolus and check the CT to define the extent of the injury completely. And then we underwent open reduction and screw fixation for the fracture. As a result, we present four cases of two part triplane fracture with extension with review of related literatures.

PURPOSE: To observe the morphological changes of the femoral head following vascular infarct produced by surgical devascularization of the capital femoral epiphysis in a mongrel puppy model. MATERIALS AND METHODS: Forty-six mongrel, weaned puppies, 7 to 9 weeks old, and between 1.5 to 2.5 kg in weight, were experimentedupon. They were divided into three groups: 12 underwent only simple capsular incision (Group A), 18 underwent ligamentum teres disruptionwith temporary subluxation of the hip joint (Group B), and 16 underwent both ligamentum teres and posterior retinacular arterydisruption (Group C). Three to five puppies in each experimental group were periodically sacrificed at 2 weeks and at 1, 2, 5 months, postoperatively. Both femurs, extracted from the sacrificed puppies, were studied by eye, radiographically and histologically. RESULTS: Puppies from the single (Group B) and double devascularization groups (Group C) showed definite findings of vascular infarct macroscopically, radiologically, and histologically. These findings were more frequent and severe in the group with the double infarct thanthe single infarct. CONCLUSION: Morphological changes similar to those seen in human Legg-Calve-Perthes' disease (LCPD) were observed in puppy specimens. This puppy model of LCPD may be useful for experimental studies.
