OBJECTIVE Granulocyte colony-stimulating factor (GCSF) is used to stimulate myeloid cell production and function in children undergoing chemotherapy for osteosarcoma. We hypothesize that GCSF can cause reconversion of marrow from fatty to hematopoietic and that this change can be detected by MR imaging at sites away from the primary tumor. This benign(More)
BACKGROUND Treatment of open fractures continues to be a challenge for orthopedic and trauma surgeons, and early treatment recommendations, which persist in the literature for decades, often do not have supporting data. METHODS This is a critical review of the literature surrounding controversies in the initial management of open fractures. It also(More)
BACKGROUND Despite the large number of anterior cruciate ligament reconstructions performed each year, there remains a significant controversy regarding the effect of the graft source on the functional outcome of patients. HYPOTHESIS There is no difference in outcomes of autograft versus allograft anterior cruciate ligament reconstructions. STUDY DESIGN(More)
OBJECTIVES The purpose of this study is to evaluate the change in quantitatively scored knee pain during union. DESIGN This is a retrospective review of prospectively collected data over a 15-year period. SETTING Academic medical center. PATIENTS All patients treated with an intramedullary nail were evaluated for knee pain and union. Four hundred(More)
OBJECTIVES To review a large series of tibial metaphyseal fractures treated with nailing in semi-extension (20-30 degrees) using a superomedial portal. To report on the quality and maintenance of reduction. To compare knee pain at final follow-up with a group nailed in hyperflexion (>90 degrees) with a standard inferior incision and parapatellar approach.(More)
PURPOSE The purpose of this study is to analyze the safety of outpatient treatment for cancer patients with chemotherapy-induced neutropenic fever in a community hospital setting and to compare the costs of outpatient treatment with those of inpatient treatment for such patients. PATIENTS AND METHODS We reviewed charts and charges for 32 consecutive(More)
OBJECTIVES Controversy exists regarding the effect of operative treatment on mortality after acetabular fracture in elderly patients. Our hypothesis was that operative treatment would confer a mortality benefit compared with nonoperative treatment even after adjusting for comorbidities associated with death. DESIGN Retrospective study. SETTING Three(More)
OBJECTIVES To report functional outcomes of displaced acetabular fractures treated nonoperatively in the geriatric patient population. DESIGN Retrospective case series. SETTING Two Level I trauma centers. PATIENTS Twenty-seven patients age 60 years or older who sustained displaced acetabular fractures during an 11-year period. INTERVENTION(More)
OBJECTIVES To assess whether plate bending at a hole significantly changes the biomechanical properties of a locked screw. METHODS Coronal plane bends of 5-, 15-, or 45-degree angles were placed in 3.5-mm locking compression plates with the apex at a locking hole. An additional 45-degree angle test group was created in which a threaded screw head insert(More)
OBJECTIVES To report the safety and clinical outcomes of placing current magnetic resonance imaging (MRI) components inside and outside the MRI bore during MRIs. DESIGN Retrospective case series. SETTING Four trauma centers (3 Level I and 1 Level II), from January 2005 to January 2015. PATIENTS All patients who had MRIs with external fixators in place(More)
