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....

Introduction: The restoration material commonly used as core material for pulpless posterior teeth is mostly amalgam due to its high strength and low cost and it can be used with or without pin. The aim of this study was to evaluate the influence of post material on stress distribution in mandibular second premolar tooth by finite element analysis. Method: The stress distribution was analyzed i...

The study evaluated the incidence of and complications associated with the use of an intramedullary nail vs open reduction and internal fixation (ORIF) with a sliding compression hip screw and plate in treating intertrochanteric fractures. The authors hypothesized that the biomechanically stronger and less invasive intramedullary nail would have superior results and fewer complications compared...

This study compared the radiographic and clinical outcomes of pediatric diaphyseal femur fractures treated by submuscular plating, flexible retrograde intramedullary nailing, or rigid antegrade intramedullary nailing with a trochanteric entry point in skeletally immature patients who were 8 years and older. A retrospective review was conducted of skeletally immature patients 8 years and older w...

BACKGROUND Several different surgical techniques have been described to address the coracoclavicular (CC) ligaments in acromioclavicular (AC) joint injuries. However, very few techniques focus on reconstructing the AC ligaments, despite its importance in providing stability. The purpose of our study was to compare the biomechanical properties of two free-tissue graft techniques that reconstruct...
