Benign soft tissue tumors in children.

Orthop Clin North Am. 2013 Jul;44(3):433-44

Authors: Thacker MM

Abstract
Soft tissue masses in children are common, yet can pose a diagnostic dilemma for the orthopedic surgeon who is asked to evaluate them. Although most lesions are dysplastic or benign, some soft tissue sarcomas are seen in the pediatric population. An understanding of the clinical presentation and imaging findings can guide the surgeon decide on the need for a biopsy and formulate an appropriate treatment plan.

Risk Factors for Metastatic Disease at Presentation with Osteosarcoma: An Analysis of the SEER Database.

J Bone Joint Surg Am. 2013 Jul 3;95(13):e891-8

Abstract
BACKGROUND: Osteosarcoma is the most common primary bone sarcoma and affects all ages. There are substantial differences in management and outcomes for patients who have localized disease compared with distant spread at the time of diagnosis. Our goal was to examine potential risk factors predictive of metastatic disease at presentation.
METHODS: The Surveillance, Epidemiology, and End Results (SEER) Program database was used to identify all patients diagnosed with osteosarcoma from 2000 to 2008 and to classify each patient as having metastatic or localized disease at the time of diagnosis. Patient-based characteristics, tumor characteristics, and county-level socioeconomic measures were analyzed to determine which factors were predictive of an increased rate of distant metastatic disease at presentation. These factors were analyzed as univariate characteristics as well as in a multivariate logistic regression model.
RESULTS: We identified 2017 cases of high-grade osteosarcoma, and 464 (23.0%) of the patients presented with metastatic disease. In the unadjusted logistic regression analysis, patients had increased odds of metastatic disease at presentation if they had an age of sixty years or more (odds ratio [OR] = 2.22; 95%

Accuracy of 3-d planning and navigation in bone tumor resection.

Abstract
Surgical precision in oncologic surgery is essential to achieve adequate margins in bone tumor resections. Three-dimensional preoperative planning and bone tumor resection by navigation have been introduced to orthopedic oncology in recent years. However, the accuracy of preoperative planning and navigation is unclear. The purpose of this study was to evaluate the accuracy of preoperative planning and the navigation system. A total of 28 patients were evaluated between May 2010 and February 2011. Tumor locations were the femur (n=17), pelvis (n=6), sacrum (n=2), tibia (n=2), and humerus (n=1). All resections were planned in a virtual scenario using computed tomography and magnetic resonance imaging fusion. A total of 61 planes or osteotomies were performed to resect the tumors. Postoperatively, computed tomography scans were obtained for all surgical specimens, and the specimens were 3-dimensionally reconstructed from the scans. Differences were determined by finding the distances between the osteotomies virtually programmed and those performed. The global mean of the quantitative comparisons between the osteotomies programmed and those obtained through the resected specimen was 2.52±2.32 mm for all patients. Differences between osteotomies virtually programmed and those achieved by navigation intraoperatively were minimal.
