El ciclo repetitivo en la Odontología Restauradora / The repetitive cycle in Restorative Dentistry

Los cambios en la vida, así como también en el campo de la Odontología, deben ser para mejorar siempre en todos los aspectos posibles. Y muchos de los cambios recientes en la Odontología Restauradora están encaminados a la utilización de materiales estéticos para remplazo de restauraciones metálicas previas, sin generar certeza total de ser mejores opciones. Esto ha generado un marcado incremento en la tendencia a practicar, más enfáticamente, el remplazo de restauraciones previas (AU)

Changes in life, as so in the field of Dentistry, should always be for the improvement on most possible aspects. Many of the recent changes in Restorative Dentistry are focus on the use of cosmetic materials to replace previous metallic restorations, without total certainty of being better options. This has generated a marked increase in the tendency to practice, more emphatically, the replacement of previous restorations (AU)

Revision Anterior Cruciate Ligament Reconstruction: Analysis of the Causes of Failure, Associated Injuries and Clinical Results / 대한정형외과학회잡지

PURPOSE: The aim of this study was to analyze the causes of failure after a primary anterior cruciate ligament reconstruction (ACLR), associated injuries, and the clinical results of revision ACLR. MATERIALS AND METHODS: This study evaluated 46 patients (46 knees), who were followed at least two years after revision ACLR. The evaluations included the causes of failure after primary ACLR, associated injuries, 2000 International Knee Documentation Committee (IKDC) subjective knee scores, Lachman test, Pivot shift test, and KT-1000 arthrometer measurement. RESULTS: The most common cause of failure was trauma (27 patients, 58.7%) and 19 failures (19 patients, 41.3%) were caused using an inappropriate surgical technique. The associated injuries were meniscus tears in 29 cases (63.0%) and articular cartilage injuries of Outerbridge grade II to IV in 19 cases (41.3%). The IKDC scores, Lachman test, Pivot shift test, and KT-1000 arthrometer measurements were improved significantly at the final follow-up. CONCLUSION: The most common cause of failure after primary ACLR was trauma. One stage revision ACLR resulted in relatively satisfactory stability but less satisfactory clinical function than the primary reconstruction, as reported previously, which is believed to be due to the more associated injuries.

Clinical Analysis of Failed Back Surgery Syndrome

One hundred thirty-five patients undergone microdiscectomy of lumbar disc disease were analysed with soft-ware program which designed for effective analysis for spinal in-patients since February, 1990. Owing to that program, all the patients could be easily analyzed and get a regular follow-up. The surgical result was evaluated by our own score rating system which consists of 4 items:1) Frequency of medication, 2) Degree of social activity, 3) Post-operative symptom compared to pre-operative state and 4) Patient's satisfaction with the operation. According to that system, 21 patients(15.6%) were estimated with failure following microdiscectomy. Among them 6 patients of psychosocial problem, 4 patients of technical errors and 2 patients of recurrence were an important causes of failure. For the purpose of effective surgery for lumbar disc surgery, a careful analysis of the cases of surgical failure should be attempted and also a regular follow-up can be importment factor for more accurate estimation of surgical result.
