Risk factors for metastatic disease at presentation with osteosarcoma: an analysis of the SEER database.
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. ⋯ Osteosarcoma patients with advanced age, a tumor in the axial skeleton, a larger tumor size, and a residence in a less affluent county were more likely to have metastatic disease at presentation.

Functional and radiographic outcomes of nonoperative treatment of displaced adolescent clavicle fractures.
Studies of adult patients suggest that nonoperative treatment of clavicle fractures may result in functional disability, but this has not been demonstrated in adolescents. The purpose of this study was to determine the functional outcomes after nonoperative treatment of displaced, shortened, midshaft clavicle fractures in adolescents. ⋯ Regardless of patient age, sports participation, and final clavicle shortening, no differences in pain, strength, shoulder range of motion, or subjective outcome scores were found between the injured and uninjured limbs of adolescents treated nonoperatively for a displaced, shortened, midshaft clavicle fracture.
