This study aims at analyzing the articulator of human body and its composition using the Magnetic Resonance Image (MRI, 0.5 Telsa). The MRI images were photographed for 1cm per every cm of human body using TR 600ms and TE 20ms spin-echo sequence. For this test, 6 healthy male subjects were sampled. The subject's heights and weights were measured before photographing and then their entire bodies were photographed in the MRI whole body scanner which has a 56cm diameter. It took 90~120 minutes to scan every subject's body during scanning the subjects were allowed to put their both hand beside their femurs. According to his height, each subject were photographed for 180~200 MR slices and every image was analyzed on the tracing paper via X-ray reading View Box. Then, the traced images were all volumized through computer scanner and CAD program, and thereupon, each volume was multiplied by its density coefficient. The results of study can be summarized as follows ; The mass of the bones occupied 8.41±0.62kg, which accounted for 11% of the body mass. The femurs accounted for 19.73±2.73% of the bone mass in terms of bodily articulation. The muscle occupied 39.70±5.28kg which accounted for 51.28±8.98% of the body mass. The part which has the richest muscle mass was femur which accounted for 33.93±5.58% of entire muscle mass. The fat accounted for 24.61±11.6% of the body mass, among which the back waist including inside intestinal fat occupied 30.66±3.64%. It was suggested through this study that MRI analysis is the most suitable method to evaluate the composition of human body and that the data acquired through MRI analysis may apply as references to other indirect or estimated evaluation of human body.

STUDY DESIGN: A retrospective review of the patients who have a fixation failure of instrumentalion for the spinal fusion in lumbar region. OBJECTIVES: To assess the incidence and different types of the mechanical failure of fixation and to evaluate their managements and their influences on the progression of a spinal fusion and to the clinical outcomes. SUMMARY OF LITERATURE REVIEW: Most of the spine surgeons have been experiencing the mechanical failures after instrumentations for a spinal fusion, eden though the incidence is decreasing with a modification of the implants. Reports on this problem are sporadic in conjunction with the other topics, rarely focusing on their management and their influences on the final outcomes. MATERIALS AND METHODS: 338 consecutive patients who had a lateral fusion in the lumbar region with an instrumentation of pedicle screws and rods, mostly with decompression, were reviewed to analyse the fixation failures of instrumentation after surgery. RESULTS: There were 26 patients (7.7%) who had the fixation failures of instrumentation, in terms of loosening around the pedicle screws in 18 patients (5.3%), the breakage of the pedicle screws in fide patients (1.5%), and the migration of a rod in three patients (0.9%). They were managed by prolonged use of brace and ergonomic back cares. Even with the fixation failures, 19 patients (73.1%) disclosed solid union uneventfully, but one patient had re-operation to obtain solid fusion. The final outcomes were satisfactory in 22 patients (84.6%), including four of six patients who had pseudoarthrosis. CONCLUSIONS: The fixation failure of instrumentation after a spinal fusion in lumbar region was not rare, but the progression of a spinal fusion usually quite well achieved and the final outcomes were not so bad, even with the implant failures and pseudoarthrosi s. Except for the persistently symptomatic pseudoarthrosis, only a prolonged use of brace and the ergonomic back cares are recommended for symptomatic patients.

The soleal line in 115 (left; 61, right; 54) cases of tibiae was studied morphometrically by the method of Mysorekar and Nandedkar. 1. The soleal line showed a uniform character throughout in 26 cases and a mixed characters in 89 cases. The bones showing uniform character were seen generally as a lineal line or wide line. 2. The soleal line having mixed characters divided into three parts. In the upper and middle thirds, the major type of line was wide line. In the lower third, the line was commonly seen as a lineal line. In about 12% of the bones examined the line was seen as a groove, particularly in the middle and lower thirds. 3. The soleal line commenced 1-2cm below the fibular facet In about 61% of cases. 4. The length of the soleal line was 10.5cm, and the ratio to that of the tibia was about 30%. The results of this study provide the characters of the soleal tne of the tibia in Korean. The soleal line, unlike the textbook description, generally shows mixed characters of a line.

Homozygous Protein C deficiency is a rare genetic disease with catastrophic and fatal purpura fulminans like or thrombotic complication occurring during the neonatal period. Purpura fulminans is characterized by microvascular thrombosis in the dermis followed by perivascular hemorrhage, necrosis, and minimal inflammation. Laboratory findings are consistent with disseminated intravascular coagulopathy: We report a case of purpura fulminans in a neonate with the findings of disseminated intravascular coagulopathy and an undetectable level of protein C activity, whose parents proved to be heterozygous protein C deficiency.

Sixteen patients who underwent 18 modified Colonna capsular arthroplasty for old unreduced DDH1 between 1984 and 1992 were recalled and critically reviewed. The average age at operation was 11.5 years (range, 8.1 to 14.5 years). The average follow-up period was 7 years and 1 month (range, 5 to 13 years). All of the patients had pain or discomfort of the hip and limp. Femoral shortening was combined in all patients, and 13 hips required concurrent pelvic osteotomy (Chiari osteotomy in 5 hips Salter innominate osteotomy in 1 hips and Steel s osteotomy in 2 hips) or slotted shelf augmentation (5 hips) due to small and shallow acetabulum relative to the femoral head. In the remaining 5 hips which had thick medial acetabular wall acetabular reaming alone was performed. At the latest followup, 9 hips showed excellent 5, good; and 4, fair results according to the modified Harris hip score and IOWA hip score. In addition, all patients except one were satisfied with the outcome in terms of regaining hip stability and decrease in pain or discomfort and limp. Radiological evaluation revealed progressive, significant increase in size of the femoral head and sphericity improvement in 12 hips. The sphericity of the femoral head did not improve in other 2 hips. In the remaining 4 hips, in which preoperative femoral head shape was relatively aspherical, the sphericity worsened after affection of ischemic necrosis or osteoarthrosis. Complications included undisplaced femoral neck fracture during physiotherapy in 2, ischemic necrosis in 2, heterotropic ossification in 2, acetabular protrusio due to too much reaming in 3 hips, and residual subluxation requiring additional pelvic surgery in 2 hips, In conclusion, we believe that modified Colonna capsular arthroplasty with femoral shortening is valid, if properly done, in the reconsruction of painful hip with old unreduced DDH in late childhood and adolesence.

In a conservative treatment of lumbar disc herniation, authors customarily had included the flexion exercise untill 1991. Thereafter, the extension exercise started to be included for the selected patients and this study was designed to assess the clinical outcome of the extension exercise compared to the flexion exercise in the conservative treatments of lumbar disc herniations. 55 consecutive patients (31 males and 24 females having ages ranging from 19-68 years with a mean of 37.2) were included in this prospective study. Criteria for inclusion in this group were: 1. Contained herniations of a single lumbar disc, documented by CT or MRI; 2. no other concurrent spine pathology; 3. conservative treatments with an uniform program including the extension exercise; 4. follow-up for a minimum of one year. For comparison with this prospective group, another 62 consecutive patients (36 males and 26 females having ages ranging from 17-63 years with a mean of 35.7) were selected who were treated during 1991 with flexion exercise before this study was designed and who were matched with the designed criteria except for the direction of exercise. Apart from the therapeutic exercise, the conservative treatments also included medication, physiotheraphy, epidural injection, and back school in the both groups uniformly. The clinical outcome of the extension exercise group indicated that 28 (50.9%) patients excellent, 23 (41.8%) patients good, three (5.5%) patients fair, and one (1.8%) patient failed outcomes. In the flexion exercise group, there were 23 (37.1%) excellent, 27 (43.5%) good, seven (11.3%) fair, and five (8.1%) failed outcomes. From these results, it would seem to follow that the extension exercise group had superior clinical outcome compared to the flexion exercise, i.e. higher excellent and good outcomes (92.7% vs. 80.6%) and lower poor and failed outcomes (7.3% vs. 19.4%), respectively, Moreover, the excellent outcome in terms of full recovery without any pain and disability was more common in the extension exercise group (50.9% vs. 37.1%). A better clinical outcome was obtained in the extension exercise group of patients who were younger than 40 years and who had a history of three months or less compared with those who were older and had longer history of disease. The sizes of disc protrusion did not affect the clinical outcome. In conclusion, we would recommend that the extension exercise, instead of the flexion exercise, should be included in the conservative treatment of a contained herniation of lumbar disc for a better clinical outcome.

PURPOSE: To investigate changes in the size and degree of signal enhancement of reperfused myocardium during the subacute stage of an ischemic episode, using Gd-DTPA-polylysine enhanced magnetic resonance imaging. MATERIALS AND METHODS: In six cats, the left anterior descending artery was occluded for 150 minutes, and this was followed by reperfusion. Contrast enhanced T1-weighted spin echo magnetic resonance imaging using gadolinium diethylene triamine penta acetic acid-polylysine (Gd-DTPA-polylysine) was performed on the 1st , 2nd, and 6th days of the reperfusion period. The size of ischemic myocardium was estimated each day on MR images by measuring the size of signal enhanced area and the degree of signal enhancement according to time was measured. After sacrificing the animals on day 6, the myocardial specimen was histochemically stained with 2,3,5-triphenyltetrazoliumchloride(TTC). RESULTS: Signal enhancement and the size of the ischemic myocardium, as seen on MR images,decreased linearly during the six days of the subacute stage. On the 6th day, however, signal intensity was still higher than that of normal myocardium, and the size of signal enhanced area measured on MR images was significantly larger than on TTC-stained specimens (p<0.001). CONCLUSION: We conclude that the size of enhanced area and degree of signal enhancement decreased linearly during the subacute stage of reperfused myocardialinfarction and that the area of MR signal enhancement during the acute stage includes both irreversibly andreversibly damaged myocardium.
