pedicle screws provide rigid fixation for instabilities in the lumbar and lumbosacral spine. anatomical consideration and potential risk of neurologic complications are the reasons to hesitate using pedicle screws in the thoracic spine. twenty moulages similar to human vertebrae were instrumented with cotrel-dubousset (cd) system pedicle screw by intratransverse process, extrapedicular and intr...

Background & Importance: Spinal deformity is one of the most common disorders among the vertebral diseases that results from unnatural curvatures of spine, such as scoliosis and kyphosis. Spinal fusion surgery is used most commonly to treat certain types of spinal deformity. Herein, we reported the efficacy of posterior spinal fusion accompanied by instrumentation in patients with the...

OBJECTIVE To analyze the surgical outcome of traumatic lumbosacral spondylolisthesis treated using posterior lumbar interbody fusion, and help spine surgeons to determine the treatment strategy. METHODS We reviewed retrospectively five cases of traumatic lumbosacral spondylolisthesis treated in our hospital from May 2005 to May 2010. There were four male and one female patient, treated surgic...

A novel cortical bone trajectory (CBT) screw technique provides an alternative fixation technique for lumbar spine. Trajectory of CBT screw creates a caudo-cephalad path in sagittal plane and a medio-lateral path in axial plane, and engages cortical bone in the pedicle. The theoretical advantage is that it provides enhanced screw grip and interface strength. Midline lumbar fusion (MIDLF) is com...

case presentation an 85 years old patient presented because of intractable right leg pain with minimal activities. she was diagnosed with significant right foraminal stenosis and she failed conservative non-invasive therapies. conclusions percutaneous lumbar hydro decompression can be a promising method for the treatment of the patients with lumbar spinal stenosis and neurogenic claudication se...

PURPOSE To compare the results of screw fixation plus capsular decompression versus screw fixation alone for managing intracapsular hip fractures. METHODS Of 201 patients with intracapsular hip fractures, 99 underwent screw fixation with capsular decompression (capsular decompression group) and 102 underwent screw fixation alone (control group). The incidence and time to development of avascu...

OBJECTIVE To investigate the incidence of C5 nerve root palsy after multi-segmental cervical decompression through different approaches. METHODS This study was conducted among 375 patients undergoing multi-segmental cervical decompression in anterior corpectomy and fusion fixation, anterior cervical corpectomy and fusion fixation + posterior decompression and fusion fixation, posterior cervic...

OBJECTIVE High-grade metastatic epidural spinal cord compression from radioresistant tumor histologies is often treated with separation surgery and adjuvant stereotactic body radiation therapy. Historically, long-segment fixation performed during posterior transpedicular of a minimum 2 levels superior inferior to the decompression. Previous experience minimal access techniques percutaneous stab...

Abstract Background The decision to treat multilevel cervical spondylotic myelopathy (MCSM) remains controversial. purpose of this study is compare the biomechanical characteristics intervertebral discs at adjacent segments and internal fixation, provide scientific experimental evidence for surgical treatment MCSM. Methods An intact C2-C7 spine model was developed validated. Four additional mod...

Complete traumatic fracture-dislocation of the lumbar spine is a rare spinal injury often leading to death. Surgical intervention is an effective treatment modality to decrease mortality. Our patient was a 16 year old boy who had a collision caused by fall from a construction material lifter. He was referred to our hospital with waist trauma. Later, the patient underwent posterior surgical deco...
