Fractures of the distal femur, proximal tibia, and patella that occur adjacent to a total knee replacement may be very difficult to treat. Fixation options are compromised because of the short articular segment, frequent comminution, pre-existing osteoporosis, previous surgical incisions, and the presence of the knee implant itself.

OBJECTIVES Open fractures are one of the injuries with the highest rate of infection that orthopaedic trauma surgeons treat. The main purpose of this survey was to determine current practice and practice variation among Orthopaedic Trauma Association (OTA) members and make treatment recommendations based on previously published resources. DESIGN Survey.(More)
As is the case in adults, the timing and type of emergent treatment of fractures in children can be controversial. Some emergent conditions, such as compartment syndrome, pelvic fractures with hemodynamic instability, and open fractures, are managed similarly in adults and children. However, other types of fractures are unique to children or are managed(More)
Periarticular fractures in elderly patients are challenging to manage because the fractures are typically comminuted and the bone is osteopenic, which often result in the failure of internal fixation. Patients who sustain these fractures demand immediate mobilization or they often do not recover their preinjury level of function. In geriatric patients,(More)
The placement of iliosacral screws for the stabilization of pelvic ring lesions is technically demanding. The postoperative computed tomography scans of 31 patients who had 57 iliosacral screws placed for various indications were studied to determine the proximity of these screws to neurovascular structures. The closest distance of the screws from the S1(More)
The aim of this study was to characterize a new model of chronic osteomyelitis with clinically relevant features. A segmental defect of critical size was surgically created in the rat femur, stabilized with a polyacetyl plate and Kirschner wires, and contaminated with bacteria. The animals were allowed to recover while the contamination progressed to a(More)
OBJECTIVES To determine if there are differences in healing, complications, or number of procedures required to obtain union among open and closed tibia fractures treated with intramedullary (IM) nails inserted with and without reaming. DESIGN Prospective, surgeon-randomized comparative study. SETTING Level One trauma center. PATIENTS Ninety-four(More)
Periprosthetic fractures of the femur represent a heterogeneous and challenging problem for the orthopedic surgeon. The incidence of these fractures is dramatically increasing, as there are more and more patients with aging total joint replacements. The fractures may occur as the result of a traumatic event, but more often are the result of minor trauma(More)
BACKGROUND Recombinant human osteogenic protein-1 (rhOP-1), combined with a collagen carrier, has been shown to induce new-bone formation in a variety of animal models. The purpose of the present investigation was to test the hypotheses that rhOP-1 would accelerate bone formation in an internally stabilized, chronically infected, critical-size defect in the(More)
Closed tibial shaft fractures are common injuries that remain challenging to treat because of the wide spectrum of fracture patterns and soft-tissue injuries. Understanding the indications for surgical and nonsurgical treatment of these fractures is essential for good outcomes. Although cast treatment of stable tibial shaft fractures has traditionally been(More)
