Clinical Results after Percutaneous Surgical Treatment of Intra-articular Fracture of the Distal Radius

PURPOSE: To evaluate the clinical and radiologic results of percutaneous surgical treatment of the intra-articular fractures of the distal radius, we have compared the results of percutaneous pinning and the combination of percutaneous pinning with external fixation after closed reduction. MATERIALS AND METHODS: We analysed the results of 52 patients with intra-articular fracture who received the operative treatment with closed reduction in the period of June, 1995 to June, 2001 and also were in regular follow-up at least one year. We used the subjective analysis by Cole & Obletz and the objective analysis by Scheck. RESULTS: We have found the outcome that 83.3% of percutaneous pinning were graded above "Good" in type B and C1 and 82.2% of the combination treatment of percutaneous pinning with external fixation were graded above "Good" in type C2 and C3. CONCLUSION: The percutaneous pinning and external fixator after closed reduction in intra-articular fractures of the distal radius are considered useful to restore the articular congruity and make good clinical results.

LCS mobile bearing knee system in Total Knee Arthroplasty

PURPOSE: The results of total knee arthroplasties using LCS mobile bearing knee system were analysed clinically and radiologically. MATERIALS AND METHODS: 57 total knee arthroplasties using LCS mobile bearing knee system were per-formed from July, 1995 to Dec.2001. There were 44 female and 10 male patients, and mean age was 66.4 years (41 years to 78 years). There were 55 osteoarthritic knees, and 2 rheumatoid arthritic knees. The average follow up period is 5.4 years (2 years to 8.3 years). ROM, and HSS knee score were analysed to evaluate clinical results. The tibiofemoral angle and radiolucent line were analysed to evaluate radiologic results. RESULTS: The preoperative mean flexion contracture is 6.8 degree, further flexion is 93.8 degree and HSS knee score is 51.3. The postoperative mean flexion contracture, further flexion and HSS knee score are improved to 2.1 degree, 124.1 degree and 88.4 respectively at final follow up. The mean tibiofemoral angle was improved from varus 5.8 degree to valgus 5.0 degree. The radiolucent lines were found in 2 knees, but the sum of the widths of the radiolucent lines was less than 4mm respectively, and were not classified as loosening. There was 1 post-operative infection case. The infection was treated with arthroscopic irrigation, IV antibiotics and daily irrigation with super oxidized soft water. There was not polyethylene dislocation or failure. CONCLUSION: LCS mobile bearing knee system showed excellent or good results clinically & radiologi-cally in short term follow up. To evaluate the radiological results of the wear and loosening of total knee arthoplasties using LCS mobile bearing knee system, continuous observation and analysis under the con-dition which excludes the external factor are necessary.

Treatment of Degenerative Lumbar Stenosis with Minimal Decompression / 대한척추외과학회지

STUDY DESIGN: A retrospective study OBJECTIVES: In the operative treatment of lumbar spinal stenosis, the wide decompression and fusion method has many problems, such as a long operation time, large blood loss and the long time required to achieve solid fusion. As a solution to these problems, a minimal decompression method was been performed, which minimizes the resection of laminae and facet joints. SUMMARY OF LITERATURE REVIEW: In the operative therapy for lumbar spinal stenosis, favorable results can be obtained by simple decompression. MATERIALS AND METHODS: 42 cases of degenerative lumbar stenosis, with neither segmental instability nor spondylolisthesis, underwent a minimal decompressive surgery, without instrumentation. The mean operation time and amount of blood loss were analyzed, and the clinical results evaluated according to Kim's criteria and the postoperative segmental instability by the Dupuis method. The average follow-up period was 70 months. RESULTS: Transfusions were not required in all cases. The mean operative times were 1hour 5minutes and 1hour 46minutes in the one and two segment decompressions, respectively. The clinical results, according to Kim's criteria, were excellent in 24 cases and good in 12. There was no dynamic instability in the radiographs at the last follow-up. CONCLUSIONS: With the degenerative lumbar stenosis, without segmental instability or spondylolisthesis, minimal decompression was an effective surgical method.
