The results and complications of pedicle screw plate (PSP) stabilizations were investigated in lumbar fresh fractures, malunions, lumbar metastases, primary tumors, lumbosacral fusions, and highgrade spondylolisthesis. The low incidence of neurologic complications of PSP is noteworthy, and a reason for recommending the method.
This article describes a technique of plating thoracic, thoracolumbar, and lumbar injuries with pedicle screw plates. The shape of the plates is premolded to the spine curvature. The strength of the pedicles where the screws are implanted explains the good results of reduction and stabilization. This technique allows the surgeon either to reduce and fix a(More)
Thirteen patients with transverse fractures of the upper sacrum were studied to determine fracture anatomy, clinical presentation, and therapeutic approaches. The injury results from falls from a height and is usually associated with suicidal attempts by jumping. The position of the lumbar spine in lordosis or kyphosis at the time of impact determines which(More)
Data for patients with bone metastases (BMs) of differentiated thyroid carcinoma (DTC) were retrospectively studied to identify factors associated with survival. We especially studied the impact of therapies. Among the 1977 patients followed for DTC in our department from 1958 to 1999, 109 (77 females and 32 males; age range, 20--87 yr) presented BMS: All(More)
The authors believe that it is not possible to remove a thoracic vertebra completely by a lateral transthoracic approach. They have operated on three patients in which a thoracic vertebra has been removed completely using an extended posterior approach. The technique described utilizes an extra-pleural bilateral thoracotomy through a single posterior(More)
Recording of cortical somatosensory evoked potentials (CSEP) enables monitoring of spinal cord function. We studied the effects of propofol, propofol-nitrous oxide or midazolam during sufentanil anaesthesia on CSEP monitoring during major spinal surgery. Thirty patients with normal preoperative CSEP were allocated randomly to one of the following(More)
Lumbo-sacral orientation in the sagittal plane is of utmost importance, as it plays a critical role in the function of the spine and the hip joints. Equilibrium of the trunk influences the tridimensional orientation of the acetabulum and the functional range of motion of the hips. Each patient is characterized by a "morphological" parameter named incidence(More)
A detailed 3D FE model of the human neck was used to assess a possible relationship between risk of injury and cervical spine curvature for various impacts. A FE model was previously developed, representing the head and neck of a 50th percentile human with a normal lordotic curvature. The model behaviour was omni-directionally validated for various impacts(More)
STUDY DESIGN The utility of the Tokuhashi score was assessed in a retrospective study in 71 patients with vertebral metastases. OBJECTIVES To study the importance of the site of the primary tumor as a parameter in the preoperative prognostic Tokuhashi score. SUMMARY OF BACKGROUND DATA A preoperative score composed of six parameters, each rated from zero(More)
Spinal epidural lipomatosis associated with Cushing's syndrome is an uncommon complication (11 reported cases). Two additional symptomatic cases with neurologic deficit are described. Steroid treatment was systemic in the first case and local with epidural injections in the second. The second case is unique because no similar observations have yet been(More)
