The purpose of this study was to investigate the immunohistochemical reaction of calcitonin-gene-related peptide (CGRP) and type II collagen and also morphological changes of cartilage implants and cultured chondrocytes isolated from the articular and costal cartilages. The chondrocytes were isolated from the head of the femur and the 11th costal cartilage of the 6 months old rabbits. De novo implants were prepared from the chondrocytes cultured on the perichondrium by culturing isolated articular chondrocytes. Cultured chondrocytes and implants were evaluated by immunohistochemical staining of CGRP and type II collagen and electron microscopy. Articular chondrocytes maintained the typical phenotype in the 1st and 2nd subcultures, but the costal chondrocytes were transformed into fibroblast-like cells. The articular chondrocytes cultured on the perichondrium were more flattened and formed the cartilage. Most chondrocytes were no loss of type II collagen immunostaining by culturing. Implants replaced by the cultured articular chondrocytes were generally increased CGRP and decreased type II collagen immunoreaction. Electron microscopically the cultured articular chondrocytes had a large euchromatic nucleus, a few granules, and abundant vesicles. During culture, the nucleus became atropy and the cytoplasm contained many large vacuoles. The chondrocytes cultured on the perichondrium showed a lot of segmented rough endoplasmic reticulum and fine short microvilli. During culture, articular chondrocytes maintained typical phenotype and type II collagen reaction. The cultured articular chondrocytes had some organelles and euchromatic nucleus with prominent nucleolus. The chondrocytes cultured on the perichondrium showed active secretion of the matrix with small vesicles and well developed endoplasmic reticulum. The implanted articular chondrocytes showed the decrease of their organelles after secretion of the marix and became increased CGRP and decreased type II collagen immunoreaction.

STUDY DESIGN: A case of brain infarction due to occlusion of vertebral artery after cervical spine fracture is reported. OBJECTIVES: Documentation of possibility and clinical significances of brain infarction as one of grave complications after cervical spine injury. SUMMARY OF LITERATURE REVIEW: Occlusion of vertebral artery and consequent brain infarction can be associated with cervical spine injuries because vertebral arteries course through the transverse foramina from sixth to second corvical vertebrae. Infarction of vertebrobasilar system may cause impairment of cerebral, cerebellar, or brain stem function and can occasionally bring grave functional loss, even death. MATERIALS AND METHODS: A case of occlusion of vertebral artery and consequent cerebral infarction after cervical spine fracture in a 66 year-old man. Brain CT and angiogram were performed. He was managed with anticoagulants. RESULTS: Neurologic deficits from brain infarction disappeared after 2 weeks. CONCLUSIONS: Attention to the possibility of these complications and awareness of their clinical features seem to be mandatory in managing cervical spine injury patients.

Total elbow arthroplasty is a relatively rare procedure compared with total knee or total hip arthroplasty. Total elbow arthroplasty for bony ankylosis is even rarer, and the results are often unsatisfactory. We report a patient who gained good mobility of the elbow after total elbow arthroplasty for the treatment of fractured arthrodesis site with which the patient had lived with for 12 years.

PURPOSE: To analyze results of treating acromioclavicular injuries using clavicle hook plates. MATERIALS AND METHODS: Between February 2008 and April 2010, 18 patients with acromioclavicular joint injury treated by clavicle hook plates were reviewed. Using the Rockwood classification, 7 dislocations were classified as type III injuries and 11 as type V injuries. Implant removal was done at least 3 months from initial fixation. Simple X-rays were taken for comparing the state of reduction, and clinical outcomes were evaluated by the Korean Shoulder Scoring System and the American Shoulder Elbow Society score. The average follow-up period was 9 months. RESULTS: On weight bearing X-rays, the average coracoclavicular distance showed a 114% increase compared to the contralateral side at the time of injury. It decreased to 23% by the last follow-up. The mean Korean Shoulder Scoring System and the American Shoulder Elbow Society score were 80 and 74 at the last follow-up. CONCLUSION: The immediate stability these plates provide allows rapid rehabilitation. Clavicle hook plate fixation for acromioclavicular joint dislocation is considered an effective method for ensuring satisfactory results both radiologically and clinically.
