Surgical Treatment for Pathologic Fracture of Skeletal Metastatic Lesion of the Proximal Femur: Comparison of Clinical Outcomes for Prosthetic Joint Replacement and Osteosynthetic Fixation / 대한골관절종양학회지

PURPOSE: To compare clinical outcomes of the tumor prosthetic replacement and osteosynthetic fixation for pathologic fracture of skeletal metastatic lesion of the proximal femur. MATERIALS AND METHODS: From 1994 May to 2009 May, medical records of 22 patients who underwent tumor prosthetic replacement with tumor resection (group 1) and 15 others (16 hips) who underwent osteosynthetic fixation without tumor resection (group 2) were reviewed. The mean age of overall patients were 59 (group 1) and 60 (group 2). Mean follow up periods were 23 and 11 months. The oncological and functional results were evaluated with Kaplan-Meier methods and Musculoskeletal Tumor Society (MSTS) scoring system, 1993. The statistical evaluation was assessed with Log rank test and t-test. RESULTS: The mean survival periods were 24 months in group 1 and 11months in group 2. The 1 year survival rates were 86% in group 1 and 50 % in group 2, and 2 year survival rates were 29.7% in group 1 and 9.4% in group 2. The mean MSTS functional score were 26.4 (19-30), 87.9% in group 1 and 15.3 (10-23), 51.0% in group 2. CONCLUSION: The results of tumor resection and prosthetic replacement in selected cases was better than osteosynthetic fixation without tumor resection for metastatic bone tumors around proximal femur in oncological and functional aspects.

Comparison of Early and Delayed Reconstruction of the ACL in Combined Injuries of the ACL and MCL of the Knee

PURPOSE: The aim of this study was to compare the results between early and delayed reconstruction of the anterior cruciate ligament (ACL) in patients with combined medial collateral ligament (MCL) injuries. MATERIALS AND METHODS: From February 2001 to January 2007, fifty-five patients who had undergone ACL reconstruction for combined ACL and MCL injuries and who were followed for more than 18 months were included in this study. The Tegner Activity Score, the Lysholm Knee Scoring Scale, the interval to recover 90degrees of motion, the Lachman test, the anterior and valgus laxity noted on stress radiograph, and the International Knee Documentation Committee (IKDC, 1993) documentation were recorded and compared between the early reconstruction group, which underwent ACL reconstruction within 3 weeks, and the delayed reconstruction group, which underwent ACL reconstruction after 3 weeks. RESULTS: At the final follow up, the Tegner score was 7.4 in the early reconstruction group and 7.6 in the delayed reconstruction group. The Lysholom score was 90.5 and 91.3, respectively (p>0.05). All the cases were rated near normal or normal on the IKDC subjective assessment. The early reconstruction group needed a longer time to recover motion and especially in the female patients. However, there was no statistical difference between the groups for the final range of motion, in addition to the Lachman test and the anterior or valgus laxity. CONCLUSION: In this study, satisfactory clinical and radiological results were obtained in both the early and delayed reconstruction groups. The early reconstruction of the ACL seems to be one of the surgical options for reconstruction of acute ACL injury combined with torn MCL.
