Long segmental fixation with TSRH posterior instrumentation for 19 patients who had unstable thoracolumbar fracture was performed between October 1992 and April 1995. The patients were followed for an average of 22 months. Measurements of the deformity angle, kyphosis, vertebral height, and the intervertebral angle were made. The patients were divided into 2 groups according to configurations of instruments for lower segmental fixation. For one group, only hooks were used, and for the others group pedicular screws and lateral offset hooks were used together at the same segment. Therefore, the purpose of this study is to anlyze the correctability following long segmental fixation and to compare one segmental fixation using both screws and lateral offset hook systems with two segmental fixation using hook systems for distal fixation. There was an overall correction of kyphosis at follow-up of 6.9degrees (27.1%) after a loss of 4.3degrees from operative correction. Overall correction of deformity angle was 8.2degrees (32.2%). Loss of vertebral height at final follow-up was 4.4%. And loss of intervertebral angle was 2.0degrees at follow-up. There was no difference of overall results between the hook group and the pedicular screw with lateral offset hook group. However, there was a significant improvement of the correction of kyphosis and restoration of vertebral height in patients who underwent operation within 7 days after injury, as compared to delayed operation. Therefore, the timing of surgery is the most important factor in order to correct the deformity caused by unstable thoracolumbar fractures. There was no significant loss of correction and no metallic failure. Therefore, rodding long with the method of one segment distal fixation using screws and lateral offset hook together can provide excellent correctability, maintenance of correction, preservation of distal lumbar joints, prevention of implant failure and complication.

Utile recently, osteotomy & reposition surgery of prominent zygoma have been performed by means of a coronal incision or intraoral preauricular incision. But penalties are paid, such as scar, the possibility of facial nerve injury and long operative time. Reflecting on our past experiences of facial bone surgery, we developed an alternative approach. In our method, the protrusion in the cheekbone is corrected by performing an osteotomy and reposition method through intraoral incision only. During the past 3 years we have operated on 23 patients of malar prominences. The amount of the bone to be removed is determined on preoperative interview, physical examination and x-rays. Intraoral incision provide access to the zygomatic body and lateral orbital rim. After L-shaped osteotomy, two paralle vertical and one transverse osteotomies, at medical part of the zygomatic body, the midsegment is removed. Posterior portion of zygomatic arch was approached through medical aspect and was outfractured using curved osteotome. After completion of triple osteotomy, the movable zygomatic complex was reduced medially and fixed with miniplates and screws on the zygomaticomaxillary buttress. The patients were followed for 9.5 months with acceptable result and little complication. The author concludes that this technique is effective and safe method in reduction malarpalsty.

Through the clinicopathologic study of pathergy test sites of 16 patients with Behrets disease in the active or inactive stage, the following results were obtained; 1. In the active stage, six of 16 patients (37.5%) showed positive reactions in clinical pathergy tests, which are much higher than that in the inactive stage when only one patient showed a positive reaction. The severity of the ciniral pathergy reaction was directly related to the activity of the disease. 2. The characteristic histopathologic finding in the active stag was a dermal inflammatory cellular infiltration composed mainly of polymorphonuclear lukocytes and of lymphomononuclear cells accompanied by leukoctocylasia. Two of 16 patients showed true leukocytoclastic vasculitis. 3. Although the type of disease and the reactivity of the clinical pathergy test were related in terms of the severity of the histopathologic findings, there were some notible histopathologic changes even in the cases with negative clinical pathergy reactions. We concluded that the histopathologic findings of the pathergy test sites were more reliable for the diagnosis of Behcet's disease than the clinical findinigs.

Bacteriological index(BI) was calculated by slit-skin smears taken from the earlobe and the dorsal surfaces of the proximal phalanges of the index finger and of the great toe in 110 lepromatous leprosy patients who have been treated regularly by antileprosy chemotherapy. The bacteriaI indices from the three sites were compared, and the results were as follows. 1) Sixteen patients whose BI of the earlobe smear was 4. 0 in average shawed the highest degree of positivity of M. leprae in the smears taken from the finger and the great toe. 2) ln seventy-four patients whose BI of the earlobe smear was l. 0 or higher, eight (10.8%) showed higher BI in smears taken from both the finger and the great toe, fifteen (20. 3%) and twenty-seven(36. 5%) showed approximately the same BI in smears taken from the finger and the great toe, respectively, 3) In thirty-six patients whose BI of the earlobe smear was negative, twelve (33. 3%) showed higher BI in smears taken from both the finger and the great toe. 4) The mean value of BI of the three sites was 3.7 in the earlobe, 3. 2 in the finger and 3. 0 in the great toe. Comparing the BI of the three sites, the finger and the great toe were found to have comparable BI with the earlobe, although the BI of the earlobe was highest. The authors concluded that it was quite reasonable to include the finger and the great toe in slit-skin smears for M. leprae identification, particularly when the BI of the earlobe was negative. A follow-up investigation seems mandatory.

PURPOSE: In order to know the clinical usefulness of the Bioscrew(Linvatec, USA) and the Semi-Fix (Arthrex, USA) technique for femoral fixation in ACL reconstruction using hamstring double loops, we scrutinized and compared the 24 knees. Materials and Methods: We compared Lysholm score, Hospital for Special Surgery(HSS) knee rating scores, Lachman tests, Pivot-Shift tests and KT side to side difference in 24 knees after arthroscopic ACL reconstruction using hamstring double loops from August 1996 to January 1998. We have used fourteen bio-absorbable interference screws and ten Semi-fixs for femoral tunnel fixation. RESULTS: We took the data; the Lysholm score of 96.1 and 94.1; HSS score of 98.6 and 98.1; KT differ- ence of 1.3 +- 2.13(mm) and 1.2 +- 1.89(mm) after ACL reconstruction using Bioscrew or Semi-Fix respec- tively. Femoral tunnel enlargement showed 2.51 +- 1.03(mm) and 1.95 +- 2.33(mm) respectively. And we got the similar results of Pivot-shift test, Lachman test and anterior drawer test after reconstructive surgery. CONCLUSION: Since we got the similar good data in comparative clinical study between the Bioscrews and the Semi-Fix technique, we anticipatd that either the use of Semi-fix technique or the biodegradable interference screws would be bright in the fixation to femoral tunnel in ACL reconstruction using ham- string double loops.

With an aging population, osteoporotic vertebral collapse is an increasingly common condition. This compression fractures has been considered a benign entity, quite responsive to conservative treatment. In a rare patients, however, a major neurologic complication and painful kyphosis despite conservative treatment can develop. Therefore, the purpose of this present study is to analyze the surgical results of 14 patients with severe back pain, an increasing kyphosis and neurologic deficits caused hy osteoporotic vertebral collapse following minor trauma, who were treated surgically. Presenting signs and symptoms included severe back pain with progression of kyphosis in 6 patients and increasing neural deficit in 8 patients. Of 14 patients, eight patients had an intravertebral cleft sign (vacuum sign). Indications for surgery included increasing kyphotic deformity, intractable pain, or increasing neurologic deficit. There was no correlation between intravertebral cleft sign and neurologic deficit. However, patients who had intravertebral cleft sign had not well respond to conservative treatment. As treatments, combined anterior and posterior fusion in 8, anterior fusion in 4, posterior instrumentation, and wide decompressive laminectomry in one patient, respectively, were carried out. The final correction of the deformity averaged 0.3 degrees. Therefore. correction of kyphosis was not favorably maintained because of variable surgical methods, and sinking of graft bone or instrumentation into the osteoporotic vertebral bodies. However, pain was reduced significantly in all patients. In addition neurological symptoms improved in 7 patients. One patient underwent reoperation with nnterior inierbody tusion together with anterior instrument because of an increasing kyphosis, neurologic. iymptoms and scvcre hack pain following wide decompressive laminectomy. There was no complication relatecl to instruments. The authors strongly helieved that surgical intervention has highly satisfactory results in patients who have intravertehral cleft sign with persistent back pain despite conservative treatment, and proressive or persistent neurologic deficits following osteoporotic vertebral collapse.
