OBJECTIVES The objective of this study was to obtain preliminary data on the relative clinical utility of direct coronary angioplasty compared with that of intravenous thrombolytic therapy for patients with acute myocardial infarction. BACKGROUND The relative merits of intravenous thrombolytic therapy and direct coronary angioplasty as treatment for acute(More)
STUDY DESIGN A prospective, randomized study. OBJECTIVE To compare the clinical results of posterior spinal fusion (PSF) with allograft augmentation versus no graft for patients with adolescent idiopathic scoliosis (AIS). SUMMARY OF BACKGROUND DATA The use of allograft has become a standard means of augmenting a PSF. Many studies have shown equal rates(More)
Anterior removal of a lumbar total disc replacement implant is often a very technically demanding procedure. The anterior retroperitoneal anatomy is prone to scarring, limiting remobilization and making a direct anterior exposure above the L5–S1 level difficult if not impossible to achieve safely. Anterolateral approach strategies can be more safely(More)
STUDY DESIGN Cohort. OBJECTIVE To compare the perioperative morbidity of patients with cardiac stents after spine surgery who continue to take aspirin before and after the operation with a similar group of patients who preoperatively discontinued aspirin. SUMMARY OF BACKGROUND DATA The preoperative discontinuation of anticoagulant therapy has been the(More)
Objective. The purpose of this study was to evaluate a new questionnaire to assess outcomes related to the midline anterior lumbar approach and to identify risk factors for negative patient responses. Methods. A retrospective review of 58 patients who underwent anterior lumbar surgery at a single institution for either degenerative disc disease or(More)
PURPOSE To study the value of Doppler echocardiography as a tool for the evaluation of left internal thoracic artery graft (LITAG) patency in patients who underwent coronary revascularization using minimally invasive bypass surgery without extracorporeal circulation. METHODS The first 12 consecutive patients were studied after coronary artery bypass(More)
PURPOSE Analysis of the first 20 patients with acute myocardial infarction (AMI) who were treated with intravenous APSAC. METHODS Twenty patients with AMI less than 6 hours of duration of symptoms were treated with IV APSAC bolus of 30 mg. Seventeen were males, ages ranging between 40 and 73 (mean 54) years. The first angiographic study was performed in(More)
The purpose of this study was to investigate the potential of a high-throughput, easily implemented, cost-effective, video analysis software-based mobility protocol to quantify spine kinematics. This prospective cohort study of clinical biomechanics implemented 2-dimensional (2D) image processing at a tertiary-care academic institution. Ten healthy,(More)
Many developing tissues display regenerative capability that allows them to compensate cell loss and preserve tissue homeostasis. Because of their remarkable regenerative capability, Drosophila wing discs are extensively used for the study of regenerative phenomena. We thus used the developing wing to investigate the role played in tissue homeostasis by the(More)
BACKGROUND Standardized pediatric hospitalist and orthopaedic co-management of spinal fusion patients may improve quality processes and outcomes. This approach has not been studied in a general academic center. OBJECTIVE Estimate relative effects and feasibility of the interventions on quality outcomes, length of stay (LOS), catheter-acquired urinary(More)
