The case definition, community incidence, and characteristics of atypical femoral shaft fractures (FSFs) are poorly understood. This retrospective study utilized electronic medical records and radiograph review among women ≥50 years of age and men ≥65 years of age from January 1996 to June 2009 at Kaiser Permanente Northwest to describe the incidence rates(More)
OBJECTIVES The purpose of this study was to characterize demographics, healing time, and complications of a large series of operatively treated atypical femur fractures. DESIGN Retrospective multicenter review. SETTING Seventeen academic medical centers. PATIENTS Bisphosphonate-related fractures as defined by American Society of Bone and Mineral(More)
Various traditional surgical treatment methods for displaced proximal humerus fractures were compared with locking plates. Ninety-eight patients were reviewed and functional outcomes were obtained. After a mean 45-month follow-up, trends were noted toward better fracture reduction with locking plates and greater range of motion (ROM) with percutaneous(More)
STUDY DESIGN The accuracy and interobserver agreement of fine detail radiography and computed tomography (CT) determination of spinal fusion were evaluated in an established animal spine fusion model. OBJECTIVE To determine the accuracy and interobserver agreement of radiographic determinations of spinal fusion in rabbit posterolateral spine fusion. (More)
The orointestinal yeast colonization of 46 children with newly diagnosed malignancies was studied prospectively and longitudinally with quantitative cultures during remission induction chemotherapy. The initial colonization rate was 24%; only 28% of the patients remained free of yeasts during their entire treatment although all of them continuously received(More)
We reviewed 46 patients who underwent salvage hip arthroplasty (SHA) for revision of failed cannulated screws (CS), sliding hip screws (SHS), or intramedullary nails (IMN). The primary objective was to determine differences in operative difficulty. SHA after failed femoral neck fixation was associated with lower intra-operative demands than after failed(More)
OBJECTIVES To examine the frequency of intra-articular placement of distal femoral traction pins and their proximity to the superficial femoral artery (SFA). METHODS Wires were placed in the distal femurs of 28 cadaveric knees at the adductor tubercle (ADT), the superior pole of the patella (SPP), and 2 cm proximal to SPP (SPP+2). A lateral fluoroscopic(More)
STUDY DESIGN Posterolateral spinal fusion with allogeneic demineralized bone graft-hyaluronan putty in addition to autogenous iliac crest bone graft in a rabbit model. OBJECTIVES To determine the potential efficacy of demineralized bone graft-hyaluronan putty as a bone graft enhancer. SUMMARY OF BACKGROUND DATA Autograft bone is the material of choice(More)
STUDY DESIGN We describe a surgical radiographic technique during anterior cervical corpectomy to define the safe lateral limit of dissection. OBJECTIVE To assess the radiographic technique accuracy using computed tomography (CT) measurements on cadaveric specimens. Two clinical cases are presented. SUMMARY OF BACKGROUND DATA During anterior cervical(More)
