UNLABELLED This study was performed to determine whether patients who sustain an intertrochanteric fracture have better outcomes when stabilized using a sliding hip screw or an intramedullary nail. A 20% sample of Part A and B entitled Medicare beneficiaries 65 years or older was used to generate a cohort of patients who sustained intertrochanteric femur fractures between 1999 and 2001. Two fra...

Although clavicle fractures often heal well with nonoperative management, current literature has shown improved outcomes with operative intervention for specific fracture patterns in specific patient types. The 2 most common methods of midshaft clavicle fracture fixation are intramedullary and plate devices. Through retrospective analysis, this study performed a direct cost comparison of these ...

A 19-year-old female patient sustained a closed spiral midshaft femoral fracture and subsequently underwent femoral intramedullary nail insertion. At followup she complained of difficulty in walking and was found to have a unilateral in-toeing gait. CT imaging revealed 30 degrees of internal rotation at the fracture site, which had healed. A circumferential osteotomy was performed distal to the...

Intramedullary spinal cord tumors (IMSCTs) are lethal diseases to many patients. The lack of adequate animal model has hampered the development of novel treatments. In the current study, a rodent intramedullary glioma model is established to study IMSCT progression. Fischer 344 rats received a intramedullary implantation of RG2 glioma cells. The neurological state of each rat was evaluated on d...

STUDY DESIGN A retrospective analysis of a prospective database. OBJECTIVE To compare preoperative symptoms, ambulatory ability, intraoperative spinal cord monitoring, and pathologic cell proliferation activity between intramedullary only and intramedullary plus extramedullary hemangioblastomas, with the goal of determining the optimal timing for surgery. METHODS The subjects were 28 patien...

Prophylactic intramedullary fi xation of impending pathologic fractures is an important preventative technique. Intramedullary rods provide longitudinal structural support, protecting weakened cortices from fracture displacement, providing pain relief, and allowing for restoration of function.1,2 In the femur, prophylactic stabilization of an impending fracture in a metastatic tumor population ...

background & importance: acute autonomic system impairment can be dangerous and life-threatening, and a clinician should be aware of its occurrence possibility. according to the anatomy of this system, spinal cord lesions could disturb its function. there are many reports of autonomic dysreflexia in spinal cord i njuries especially spinal cord trauma. case presentation: a 28 year-old man with a...

BACKGROUND AND PURPOSE Tibial tubercle osteotomy (TTO) is an established surgical technique for exposing the stiff kneein revision total knee arthroplasty (RTKA). The osteotomy is usually performed through the anterior metaphyseal cancellous bone of the tibia but it can be extended into the intramedullary canal if tibial stem and cement removal are necessary. Furthermore, repeat osteotomy may b...

BACKGROUND AND PURPOSE It is not known whether there is a difference in bone healing after external fixation and after intramedullary nailing. We therefore compared fracture healing in rats after these two procedures. METHODS 40 male rats were subjected to a standardized tibial shaft osteotomy and were randomly assigned to 2 treatment groups: external fixation or intramedullary nailing. Evalu...

Neurocysticercosis is the most common central nervous system (CNS) parasitic disease worldwide, but spinal cysticercal infection is relatively rare, especially in the United States. Because of increased immigration to the United States from endemic areas, the incidence of neurocysticercosis has risen, especially in California, Texas, Arizona, and other southwestern states, but not in Wisconsin....
