OBJECTIVE To develop current birth weight norms by gestational age for singleton and twin births in Canada. METHODS Birth weight data were obtained from vital statistics and health department birth registrations for over one million live births in Canada from 1986-1988. Unlikely combinations of birth weight and gestational age were defined within each(More)
The records of 140 patients with histologically verified Ewing's sarcoma of bone treated between 1969 and 1982 were studied retrospectively. Various factors thought to be relevant to prognosis were analyzed. Three statistically significant factors were found: presence of metastatic disease, elevation of the sedimentation rate, and location of the tumor in(More)
UNLABELLED A prospective study using a dose-intensified neoadjuvant intra-arterial chemotherapy regimen was designed to improve survival rates of young patients with primary, nonmetastatic osteosarcoma of the extremity. Arteriography was implemented to individualize duration of therapy by serially assessing change in tumor neovascularity. Intravenous(More)
Metastatic lesions to bone outnumber primary bone malignancies. Osseous metastases to the tibia tend to be less common than osseous metastases to other long bones. This study examined the treatment options for a population of patients with metastatic disease to the tibia, with surgical intervention being the cornerstone of treatment for the osseous lesion.(More)
Unicameral, or solitary, bone cysts are unusual tumors seen in the ends of long bones in skeletally immature persons. The etiology of these lesions is poorly understood. Various hypotheses have included dysplastic processes, synovial cysts, and abnormalities in the local circulation. Most patients present with a nondisplaced pathologic fracture, but(More)
Long bone defects due to nonunion or surgical excision of benign bone tumors result in areas that require rapid regeneration of local bone. This clinical and radiographic article details the results of a commercially prepared allograft demineralized bone matrix in patients with long bone voids or gaps. Of the 76 patients included for study, 41 (54%)(More)
Background: A protocol to treat osteosarcoma of the extremity was developed at two local institutions. Methods: The study involved a dose-intensified neoadjuvant protocol of intravenous doxorubicin and intra-arterial cisplatin administered repetitively until maximum angiographic response was noted. Definitive surgery was delayed until ≥90% reduction in(More)
A noninvasive expandable prosthesis for skeletally immature children after limb salvage surgery has been developed. Between 1998 and 2001, 18 Phenix prostheses were implanted in 15 pediatric patients who had been diagnosed and treated for osteosarcoma about the knee. Of the 15 original prostheses, 10 were implanted at the time of primary tumor resection and(More)
Sixty-six patients with 69 "stiff" nonunions (no gross motion) of long bones were entered into a prospective study. The only therapeutic intervention was the percutaneous administration of a mixture of autologous bone marrow and allograft demineralized bone matrix on an outpatient basis. Sixty-one of the percutaneous treatments (88%) resulted in union at an(More)
