BACKGROUND Short-segment U-shaped pedicle screw fixation has been widely used to treat thoracolumbar burst fracture. Some studies have reported the disadvantages of traditional U-shaped pedicle screw, which included a relatively high rate of adjacent segment degeneration and screw failure, including screw pullout and breakage. The purpose of this study was to assess the efficacy of open reducti...

Surgical correction with corpectomy and subsequent fusion of neighboring levels is a commonly practiced treatment for thoracolumbar burst fractures. Different fixation constructs are currently implemented to fuse the injured level. However, little is known about the implications of such constructs on the biomechanics of the adjacent spine segments. The objective of this study is to compare the ...

Interbody fusion with posterior instrumentation is a common method for treating lumbar degenerative disc diseases. However, the high rigidity of the fusion construct may produce abnormal stresses at the adjacent segment and lead to adjacent segment degeneration (ASD). As such, biodegradable implants are becoming more popular for use in orthopaedic surgery. These implants offer sufficient stabil...

Aim: The current study aimed to evaluate the late-term results of patients operated for lumbar spine fractures in our clinic. 
 Material and Method: 134 from January 2012 2020 were treated with “short-segment pedicle instrumentation” neurosurgery department. Patients a burst fracture single vertebra included. final sample consisted 67 who followed up over years radiographs before after sur...

Objective The purpose of this study is to evaluate the efficacy and safety of 3-level hybrid surgery (HS), which combines fusion and cervical disc replacement (CDR), compared to 3-level fusionin patient with cervical spondylosis involving 3 levels. Methods Patients in the anterior cervical discectomy and fusion (ACDF) group (n=30) underwent 3-level fusion and the HS group (n=19) underwent com...

t I I Study Design. For in vitro studies, there is no basis t for choosing a "load control study" over a "displace: ment control" study. This study qualitatively compared f results from in vitro and in vivo tests, allowing the au€ : thors to address the experimental assumptions that in vitro testing contributes to the understanding of the in vivo condition. Objectives. To compare motion changes...
