STUDY DESIGN Prospective randomized study. OBJECTIVES.: To compare the results of the combined anterior-posterior surgery (Group A) with posterior "short-segment" transpedicular fixation (SSTF) (Group B) in mid-lumbar burst fractures. SUMMARY OF BACKGROUND DATA There are no comparative randomized clinical studies on the outcome following operative(More)
BACKGROUND Authors of recent studies have reported early periprosthetic osteolysis in patients who have been treated with a contemporary metal-on-metal total hip arthroplasty and have suggested that metal hypersensitivity associated with an immunologic response to metal may be of etiologic importance. We evaluated the results and histologic findings in(More)
Delayed complications following lumbar spine fusion may occur amongst which is adjacent segment degeneration (ASD). Although interspinous implants have been successfully used in spinal stenosis to authors’ knowledge such implants have not been previously used to reduce ASD in instrumented lumbar fusion. This prospective controlled study was designed to(More)
STUDY DESIGN A prospective study conducted on several roentgenographic parameters of the standing sagittal profile of the spine in an asymptomatic Greek population. OBJECTIVES To perform segmental analysis of the sagittal plane alignment of the normal thoracic, lumbar, and lumbosacral spines and to compare the findings with those derived from similar(More)
STUDY DESIGN Prospective consecutive series. OBJECTIVE To evaluate the outcomes of the treatment of acute thoracolumbar burst fractures by transpedicular balloon kyphoplasty with calcium phosphate cement and posterior instrumented fusion. SUMMARY OF BACKGROUND DATA In the surgical treatment of thoracolumbar fractures, the major problem after posterior(More)
STUDY DESIGN Prospective controlled cohort study of 27 adult osteoporotic patients who underwent kyphoplasty for fresh osteoporotic spinal fractures. OBJECTIVES To define the evolution of vertebral bone mineral density (BMD) at kyphoplasty and adjacent levels along with sagittal spinal alignment to contribute to the etiology of adjacent vertebral(More)
This prospective longitudinal randomized clinical and radiological study compared the evolution of instrumented posterolateral lumbar and lumbosacral fusion using either coralline hydroxyapatite (CH), or iliac bone graft (IBG) or both in three comparable groups, A, B and C, which included 19, 18 and 20 patients, respectively, who suffered from symptomatic(More)
This cross-sectional study was carried out to investigate any correlation between backpack carrying, spinal curvatures, and athletic activities on schoolchildren's dorsal (DP) and low back pain (LBP). Three thousand four hundred forty-one students aged from 9 to 15 years who carried backpacks to school were included in this study and asked for DP and LBP(More)
STUDY DESIGN A prospective study was conducted in a young homogenous adolescent population, with the use of the scoliometer. OBJECTIVES To create a mathematic formula that provides the accurate Cobb angle of idiopathic scoliosis with the use of the scoliometer only. SUMMARY OF BACKGROUND DATA The scoliometer is an accepted method for detection and(More)
