STUDY DESIGN: The treatment of a stable fracture around thoracolumbarjunction is a controversial subject. OBJECTIVES: To evaluate the result from long term follow-up of the stable spinal fracture around thoracolumbar junction according to the operation, osteoporosis and in situ extension bar, respectively. SUMMARY OF BACKGROUND DATA: The thoracolumbar junction is a transitional zone in which the kyphotic angle of thoracic spine is continued to the lordotic angle of lumbar splne. So it is prone to be injured biomechanically, and the stability of the spine around thoracolumbar junction is not determined yet. METHODS: We studied retrospectively 105 cases of the stable fracture around thoracolumbar junction from January 1985 to December 1995. The criteria of the stability were a compression fracture by Denis F., a bursting fracture without involvement of posterior column, a neural enchroachment of bony fragment below 30%, fracture without subluxation or dislocation in spinal junction. RESULTS: The most common cause was traffic accident and, the first lumbar vertebrate was common site. Below 30% of initial compression, the progression was not exceded 5% in operative group. But in nonoperative group, anterior compression was more progressed than initial compression over 5%. The degree of anterior compression was affected by osteoporosis and in situ extension bar just after injury. CONCLUSIONS: We suggest an anterior compression abode 30% in spinal body of thoracolumbar junction for an additional operative indication. The prognosis may be affected by osteoporosis and in situ extension bar.

STUDY DESIGN: The purpose of this study was to determine whether facet joint orientation and/or tropism influences the prevalence of disc degeneration in MRI in young patients. OBJECTIVE: 41 patients with disc degeneration disease including HNP in MRI were assesed on facet joint angles and tropism between 18 and 30 years old. SUMMARY OF BACKGROUD DATA: The patients who had back pain had association between disc degeneration and facet tropism in adults. But some authors have suggested that facet tropism has no clinical relevance. Physiologic aging and premature disc degeneration induce a gradual loss of water and proteoglycan from nucleus pulposus. METHODS: We reviewed the 41 MRI of lumbar spine with disc degeneration and measured facet joint angles on the mid-disc cut, which was parallel to inferior vertebral end-plate of superior vertebra. In simple X-ray, we reviewed relation between the transitional vertebrae and disc degeneration. It was analyzed statistically the facet joint angles and facet tropism in each levels. RESULTS: The mean facet angles was more increased in upper vertebral facet joints but statistically nonspecific. The facet tropism was not significant in all lumbar levels and the effects of transitional vertebrae on disc degeneration were ignorable and unclear. CONCLUSIONS: No statistical relationship was found among the magnitude of the angle and facet tropism and the presence of disc degeneration at any levels in young patients.

A review of 15 cases of the modified Bristow operation for recurrent anterior shoulder dislocation from Jan. 1983 to Dec. 1988 was presented. Using arthroscopy, we could examined the pathologic feature of the recurrent anterior dislocation of the shoulder. The results are as following. 1. The ages at the initial dislocation were ranged from 15 to 26 years and operated from 19 to 61 years. 2. The most common injury mechanism of the dislocation was sports injury (5 cases) and followings were traffic accident, military training, hanging with one hand. 3. The 10 cases were dislocated above 10 times before operation and 3 were dislocated above 10 times per year. 4. Bony lesions were detected on routine X-ray at 8, that is A-P and lateral view, Hill-sach's view, Stryker-notch view and West point view, Hermoddson view, and apical obique view. 5. Arthroscopic examination was done at 7 cases and could detect the pathologic lesion more exactly. 6. All were treated with modified Bristow method 7. Mean follow up periods were 2 year and 4 monthes. 8. The range of motion was not limited but external rotation was done about 18. 9. Excellent results were obtained by Rowe's grading system, mean 88.8.

PURPOSE: To determine the accuracy of MRI on postoperative pain syndrome (POPS), including early complications such as hematoma or infection. MATERIALS AND METHODS: Of the 54 patients with the POPS, we analyzed pre-operative MRI findings compared with operative findings on 39 patients, excluding nonunion, instability, metal failure and pseudarthrosis, who underwent an operation for POPS from December 1994 to June 1997. There were 25 men (64.1%) and 14 women (35.9%), aged from 16 to 68 years (average 44.5 years). They were divided into 5 subgroups and calculated for sensitivity, specificity and positive predictability. RESULTS: MRI accuracy in recurred disc was 84%, scar adhesion, recurred or developed stenosis, infection and hematoma was 100% for each overall accuracy of MRI was 93%. Average interval of reoperation in POPS was 3.2 years. In 21 cases (53.8%), symptoms persisted without pain-free interval after first operation. CONCLUSIONS: Early complications, including hematoma and infection, are easily detected with MRI. Especially if patient complains of severe leg pain or neurologic deficit, MRI is a good diagnostic tool. MRI is a useful method for evaluation of most cases of POPS, but it is limited in evaluating recurred disc or scar adhesion only in T1, T2 weighted image. Therefore, Gd-DTPA enhancement is necessary for an accurate diagnosis.

Cubitus varus deformity is the late complication of the supracondylar fracture of humerus which is common in growing children. If the deformity is severe it causes tunctional problems as well as cosmetic ones necessitating conective osteotomy. Though many authors devised different methods of corrective osteotomy, the cosmetic results are not always satisfactory because of the development of the lazy S deformity hy the lateral prominence. Technically. the initial stahility of the osteotomy is also poor due to the poor contact of the osteotomy site. So we have devised a new quadrilateral displacement osteotomy to increase the initial stability of the osteotomy by creating a wedge on the osteotomy site & also to prevent the development of the lazy S deformity hy elimination of the Interal prominence. We treated 9 cases of cubitus varus deformity with the new quadrilateral displacement osteotomy. The correction technique was not difficult & the initial stahility of the osteotomy is rather good & the osteotomy is fixed by the conventional methods, & all of the cases were healed uneventfully. There developed no the lazy & deformity after osteotomy. We would like to report the details ot the supracondylnrquadrilateral displacemenl osteotomy.

A case of Lymphangiomatosis of the skeleton and soft tissue in a 23 years old woman is presented. Lymphangiomatosis are benign tumors formed of lymphatic vessel and like hemangiomatosis are probably best thought of as harmatomatous malformation. As term imply, the endothelial space in these lesions are lymph-rather than blood containing. Bone involvement are very rare condition that affect mainly the ilium and features a largely lytic pattern, consisting of tiny elliptical radiolucents slots. Treatment and Prognosis depend on the site and extent of involvement and progression. Although irradiation may be the treatment of choice, the lesions have not been usually successfully treated.

Ligament and tendon prostheses have all suffered because of failure of the particular material that has used in the past. Various materials, including, silk, nylon, Dacron, and combinstions of other synthetic substances, have all enjoyed temporary vogues and have vogues and have all passed out of habitual use because of collapse of the material employed. In an attempt to find an alternative material for use as a tendon or ligament prosthesis, a fundamentally new approach to the problem has been used, namely, that of tendon ligament induction. Carbon fiber has an attraction as a biologic implant because of its inherently inert nature when used in the pure form. Within recent years, it has been possible to manufacture filamentous carbon fiber of high purity and constant filament size, and this material has been examined as a tendon and ligament prosthesis. Both achilles tendons of 14 adult Korean rabbits were replsced with carbon fiber reinforced epoxies(CFRE, it was developed in department of chemical engineering, Chungnam national university, Daejeon, Korea) after artificially rupture, and serial histologic examination of neotendon formations and biologic responces in vivo were done during 8 weeks. The results obtained were as followings ;1. Hemorrhage and inflammatory reactions were observed at 2–3 weeks after operations. 2. Foreign body reactions were developed at 4 weeks after operation, also observed proliferations of foreign body giant cells and histiocytes. 3. Fibroblasts were increased at 4 weeks after operation, and most severe poliferations at 5–6 weeks. 4. Foreign body reactions and fibroblasts were markedly decreased at 7–8 weeks after operation, and examination of the collagen itself showed it to be closely similar to that found on the normsl side.5. Thus, it appeared that the carbon fiber initially acted as a tendon prosthesis.
