1.Diagnosis and Management of Pulmonary Atresia with Major Aorto-Pulmonary Collateral Arteries.
Korean Circulation Journal 1989;19(3):473-482
Pulmonary atresia with major aorto-pulmonart collateral arteries(abbreviated as MAPCA in the following)as a route for pulmonary blood flow presents many problem in diagnosis and management and recently new approach to surgical management (unifocalization)was suggested and few reported it's application. Nineteen cases who had pulmonary with MAPCA, diagnosed at Seoul National University Children's Hospital from October 1987 to May 1989, were studied to lool at the relationship between MAPCA, central pulmonary artery and segmental pulmonary arteries. Also was observed the clinical course and operative management. The average number of MACPA in each patient was 4, two toward right lung and the other two toward left lung. MACPA arose most frequently from descending aorta and innominate artery contralateral to the side of aortic arch. Central pulmonary artery was identified in 86.7%. The number of bronchopulmonary segment connected to central pulmonary artery directly or indrectly was very variable so was the number of bronchopulmonary segment connected to MAPCA only. Three had a total correction and 14 had a various kinds of palliative operation once or twice. Seven had a called "unifocalization"(connection of MAPCA to central pulmonary artery) to correct arborization abnormality but the result was not satisfactory for technical reason.

2.PCL Reconstruction Using Semitendinosus Tendon
The Journal of the Korean Orthopaedic Association 1996;31(5):1007-1012
The posterior cruciate ligament(PCL) is one of the most important structures in the knee joing because it provides about 94% of the total restraint to posterior displacement of the tibia & posterior stability of the knee joint. If the posterior instability persisted, rotational instability, injury to meniscus and degenerative change develop within several years. The purpose of this study is to know the result of the posterior cruciate ligament reconstruction using semitendinosus tendon and to know the factors which affected to good result. During the period from January 1989 to December 1994, 16 cases with posterior cruciate ligament reconstruction using semitendinosus tendon were evaluated clinical and radiological results retrospectively and performed stastical analysis using the SPSS. The results were as follows; 1. The average preoperative posterior laxity was 14.1 mm and average postoperative laxity was 6.3 mm. It was improved 7.8 mm. 2. In other associated injured ligament group with or without fracture, above good was in 8 cases and below fair in 6 cases, but there was no significant difference between the two (X²=9.8, df=1, P>0.05). 3. In the poor result group, mean body weight was 80(±13.23)kg and there was significant difference between poor group & fair, good, excellent group(F=3.52, P < 0.05). From these results it would be suggested that PCL reconstruction using semitendinosus tendon is more effective in relatively light weighted group than heavier group.

STUDY DESIGN: This study analyzed the efficacy of the reduction and its maintenance using the posterior pedicular screw system in adult patients undergoing surgical treatment for symptomatic, isthmic spondylolisthesis. OBJECTIVE: To evaluate the effect of the reduction for lumbar isthmic spondylolisthesis in adult. SUMMARY OF LITERATURE REVIEW: If the increase of the shear force is approved as a main biomechanical feature of spondylolisthesis, reduction of the shear forces to the physiologic level must be regarded as the goal of surgical treatment. MATERIALS AND METHODS: 11 cases were treated with posterior monosegmental two point f;cation and posterolateral fusion (Group 1), 8 cases with a combined surgery of posterior monosegmental two point fixation, posterolateral fusion and anterior interbody fusion (Group 2), and 20 cases with posterior two segmental three point fixation and posterolateral fusion (Group 3). We assessed the clinical results and the radiologic objective parameters. RESULTS: The patients were followed up for more than 2 years (mean : 64 months). The satisfactory clinical results were 9 cases (81.8%) in Group 1 ,7 cases (87.5%) in Group 2 and 17 cases (85%) in Group 3. Radiologically, the efficacy of reduction and its maintenance were satisfactory results in Group 2, and the changes of the slip angle and the disc height showed that the loss of correction was greater than postoperative correction, although there were no statistical significant differences in the three groups. CONCLUSION: According to the our results, there was no significant relationship between the clinical result and the rdiological one. However, we think that the correcton of the deformity using the posterior pedicular screw system have some biomechanical advantages and seem to be recommendable for the treatment of isthmic spondylolisthesis in adults.

From September 1987 to June 1994, the authors had performed posterolateral fusion in one patient, anterior spinal fusion alone in four patients, anterior spinal fusion after posterior augmentation with Rectangle Luque and posterolateral fusion in four patients of tuberculosis of the lumbosacral junction. The purpose of this study was evaluated the reliability of the posterior augmentation with Rectangle Luque and posterolateral fusion. We divided into two groups: the study group was anterior spinal fusion after posterior augmentation with Rectangle Luque in four patients, the control group was anterior spinal fusion alone in four patients. The average follow up was obtained at 16 months(12 to 20 months) in study group, at 42.7 months in control group. Results were as follows: 1. Clinical results according to Moskowitz criteria were 2 patients with grade I. 2 patients with grade II in the study group; one patient with grade I, one patient with grade II, one patient with grade III, one patient with grade IV in the control group. Hypolordosis(less than 10 degree) at the lumbosacral junction was associated with a higher incidence of back pain. 2. Radiographically well consolidated anterior fusion was noted in all patients within average 6 months (5-7 months) in the study group and 7.2 months (5-10 months) in the control group. 3. Radiologically the lumbosacral saggital angle was corrected after operation and the mean angle was 16.5 degrees(12 to 20 degrees) in the study group, 7.2 degrees(3 to 20 degrees) in the control group. The mean loss of angular correction was 5 degrees(1 to 8 degrees) in the study group, 6.2 degrees(1 to 13 degrees) in the control group at postoperative one year follow up. In conclusion, this results suggest that the anterior spinal fusion concomitant with the posterior augmentation with Rectangle Luque is the recommendable methods for tuberculosis of the lumbosacral junction in adults.

Potentially, some donor site complications are associated with the harvesting of autogenous tricortical iliac bone grafts for anterior spinal fusion. The purpose of this study was to evaluate the reliability of the anterior iliac crest reconstruction after harvesting autogenous iliac grafts for anterior spinal fusion. We devided into two groups : the study group were the anterior iliac crest reconstruction in 57 patients with minimal twelve months follow up period, the control group were not the anterior iliac crest reconstruction in 21 patients who could not obtain the rib from retroperitoneal approach. The average follow up was obtained at 43.3 months(12 to 72 months) in study group, at 41.6 months(12 to 60 months) in control group. The study group had a tendency to improve the donor site pain after incorporation of the rib graft and the control group tend to remain the donor site pain till late especially in the thinner group and combined disease group. In residual deformity of the donor site, the study group was superior to the control group. Residual deformity of the study group was associated with the complications such as displacement and resorption of the grafts. Cosmetic residual deformity tends to be higher in the thinner group. Radiographically all rib gragts incorporated in situ in 51 patients despite of some cases of migration(Average 11 weeks and 4 days) and clinical results did not affect by biological behavior of rib grafts on the follow up radiogram. The authors attempted anterior iliac crest reconstruction using the implants (Mennen plate in 3 patients, threaded pin in 3 patients) after large harvesting of autogenous tricortical graft in 6 patients who could not obtain the rib from retroperitoneal approach or could not fit the rib too the defect. In those cases the results were satisfactory clinically. These results suggest anterior iliac crest reconstruction can minimize painful deformity after the harvesting of autogenous tricortical iliac grafts for anterior spinal fusion.

The Graf system has supposed advantages with its flexible nature, as compared with rigid fixation. But there have been no reports about effects in the adjacent motion segment after soft stabilization. The purpose of this study was to evaluate the radiologic changes occuring in the adjacent segments of the Graf system and to assess its ability stabilizing the lumbar spine. A retrospective review of radiographs and medical records was undertaken in 32 cases who had been treated with the Graf system in degenerative lumbar spinal disorders. The average age at operation was 52.5 years and the average follow up period was 49.6 months. The results of this study were as follows: clinical assesments based on the Kirkaldy-Willis criteria revealed excellent in 13 cases (40.6%), good in 16 cases (50%), fair in 2 cases (6.3%) and poor in 1 case (3.1%). Radiologically we analysed the adjacent segments in 25 cases except the cases which did not have the correspondence between the clinical findings and the radiological findings, and the fixated segments in 32 cases. The acceleration of degenerative changes were found in the above adjacent segments in 11 cases (44%) and in the below adjacent segments in 5 cases (27.7%). Also, those changes were found in the fixated segments with discectomy in 19 cases (50%) and in the fixated segments without discectomy in 9 cases (37.5%). In conclusion, we think that the Graf system in a lumbar region may biomechanically influence the adjacent segments. The mechanical effects of the device could be changed by the polyester bands which were followed for a longer period of time in the fixated segments. Therefore, randomized prospective studies comparing the Graf system to other treatement methods could provide clear indications for lumbar spinal disorders.
