T he normal lordotic curvature of the cervical spine is critical to maintaining sagittal alignment and spinal balance. 9 , 17 , 18 The reversal of normal cervical curvature, as seen in kyphosis, can occur through a variety of mechanisms and can lead to mechanical pain, neurological dysfunction, and functional disabilities. 1 , 2 , 4 , 11 , 12 When patients present with sufficient symptomatic deformity, surgical intervention may be warranted. It is believed that the neurological symptoms seen in cervical kyphosis are a result of deformity

thoracolumbar spine describes a subset of fractures with posterior ligamentous complex disruption in response to a flexion and distraction moment imparted to the thoracolumbar spine. These injuries are mechanically and neurologically unstable and surgical stabilization is frequently necessary to prevent neurological deterioration and maintain sagittal alignment. Conventionally, open posterior fixation and fusion have been utilized as the standard surgical treatment. Recently, percutaneous techniques with pedicle screws insertion are becoming popular as they provide

Background/Introduction: Transforaminal lumbar interbody fusion (TLIF) has become a popular surgical option to complement posterolateral fusion (PLF) for treatment of degenerative spinal conditions. Purported advantages of TLIF over PLF alone include enhanced fusion rates, improved sagittal alignment, and direct decompression of the neuroforamen. Earlier studies have examined these issues and yielded inconclusive results. Another often suggested advantage, that TLIF provides superior immediate stability and protects against early pedicle screw loosening, has never been
