OBJECTIVE To analyze and describe the distance from the popliteal artery to three specific areas of the proximal region of the tibia, with the knee extended, by means of magnetic resonance. METHODS Images of 100 knees of patients who underwent magnetic resonance examinations were analyzed. The location of the popliteal artery was measured in three different areas of the posterior proximal reg...

Traumatic dislocation of the hip or knee can occur after high-energy trauma and is often associated with concomitant injuries and secondary complications. Concomitant traumatic dislocation of both hip and knee is rare. We describe a case of combined ipsilateral posterior hip dislocation with a posterior acetabular fracture and a complete open knee dislocation with disruption of the popliteal ar...

BACKGROUND Popliteal artery war wounds can bleed severely and historically have high rates of amputation associated with ligation (72%) and repair (32%). More than before, casualties are now surviving the initial medical evacuation and presenting with severely injured limbs that prompt immediate limb salvage decisions in the midst of life-saving maneuvers. A modern analysis of current results m...

More than 1 million knee injuries are treated annually in North American emergency departments (EDs). These injuries range in severity from minor contusions to limb-threatening injuries to the popliteal artery. The knee joins the longest mechanical levers in the body, the femur and tibia, and is therefore subject to high forces. It is the largest and most complex joint in the body and functions...

The lower-extremity vascular injuries and neuropathy are the most salient complications of diabetes which could lead to the poor prognosis, especially for the type II diabetes. The lower extremity vascular injuries and neuropathy usually coexist, yet their correlation in the pathogenesis of lower extremity lesions has received little attention in previous studies. To investigate the correlation...

Fractures of the proximal epiphysis of the tibia are rare, representing 0.5 to 3.0% of all epiphyseal injuries. These injuries can damage the popliteal vessels and their bifurcation, affecting the blood supply of the lower limb, as well as the nerves below the knee. Epiphyseal growth arrest is also a potential complication, leading to various angular deformities. We present a case of a 13-year-...

This guide to ultrasound imaging of the knee describes basic scanning planes and contains corresponding high-resolution images. The patient probe positionings are explained in a simplified step-by-step manner using schematic drawings. standard simple examination technique seems be an appropriate way improve learning curve novice musculoskeletal sonographers. In this manuscript, emphasis is plac...

BACKGROUND Limb amputation due to lower extremity arterial injury is not uncommon and multilevel arterial injury is even more limb-threatening and easily missed with potentially devastating consequences. There is limited information on multilevel arterial injuries. PURPOSE We undertook a review of our experience to gain insight on multilevel arterial injury patterns associated with lower extr...

PURPOSE The purpose of this study was to evaluate our experience with the diagnosis and management of vascular injuries in a group of high-performance athletes. METHODS Between June 1994 and June 2000, we treated 26 patients who sustained vascular complications as a result of athletic competition. Clinical presentation, type of athletic competition, location of injury, type of therapy, and de...
