Using a new tool developed in our laboratory to quantify local pressure changes on an artificial spinal cord, quantitative results correlating fracture/soft tissue pathology with cord pressure changes, was accomplished. Human cadaveric head-neck complexes were dynamically loading by fixating the inferior of the preparation and removing the cadaver spinal cord The instrumented artificial spinal ...

OBJECTIVE The diagnosis of insufficiency fractures of the sacrum in an elder population increases annually. Fractures show very different morphology. We aimed to classify sacral insufficiency fractures according to the position of cortical break and possible need for intervention. METHODS Between January 1, 2008 and December 31, 2014, all patients with a proven fracture of the sacrum followin...

UNLABELLED BACKGROUND Ankylosing spondylitis (AS) is a rheumatoid disease leading to progressive ossification of the spinal column. Patients suffering from AS are highly susceptible to unstable vertebral fractures and often require surgical stabilisation due to long lever arms. Medical treatment of these patients improved during the last decades, but until now it is unknown whether the annua...

Nonunion and C1-C2 instability of odontoid fractures usually result from delayed diagnosis and inappropriate treatment. However, the available treatment options for odontoid fractures remain controversial. The authors evaluated the effectiveness of internal screw fixation via the C1 and C2 pedicle in cases of old odontoid fractures. This retrospective study included 21 patients with old odontoi...

STUDY DESIGN Retrospective chart review. OBJECTIVES To determine the frequency of stable and unstable cervical spine fractures after gunshot wounds to the head or neck; to identify potential risk factor(s) for an unstable versus stable cervical spine fracture. SUMMARY OF BACKGROUND DATA Cervical spine fractures after gunshot wounds to the head and neck are common. Because of the nature of t...

OBJECTIVE To evaluate the applicability of the WHO densitometric criteria for the diagnosis of spinal osteoporosis in men and to compare it with women with vertebral fractures, as well as to analyze the role of vertebral dimensions in the development of spinal fractures. METHODS For these purposes we analyzed, using DXA, vertebral projected area and lumbar bone mineral density (BMD), as well ...

BACKGROUND Spinal cord injury (SCI) is a devastating condition often affecting young and healthy individuals around the world. This debilitating condition not only creates enormous physical and emotional cost to individuals but also is a significant financial burden to society at large. The Objective was to study the outcome of spinal fixation with fixateur interne in cases of thoracolumbar spi...

The increased rate of fracture healing and abundant callus formation of long bone fractures in patients with concomitant severe acute traumatic head injury is a well-known orthopedic phenomenon, Few studies, however, have reported these phenomena being induced by acute traumatic Spinal Cord Injury (SCI). There is also a well-established clinical relationship between spinal cord injuries and het...

background and aims: one of the most common injuries around the world is the traumatic injury of the spine and spinal cord with unknown worldwide situation of traumatic spinal cord injury (tsci) affecting on the effectiveness of preventive policy programs. in addition, because of possibility of making paralysis, the potential injury to the spine could be one of the most important traumas and a ...

Study Design In vitro biomechanical study. Objective To investigate the biomechanics of thoracolumbar burst and Chance-type fractures during fall from height. Methods Our model consisted of a three-vertebra human thoracolumbar specimen (n = 4) stabilized with muscle force replication and mounted within an impact dummy. Each specimen was subjected to a single fall from an average height of 2.1 m...
