Object The long-term outcome of lumbar dynamic stabilization is uncertain. This study aimed
to investigate the incidence, risk factors, and outcomes associated with screw loosening in a …

Objective To analyze the biomechanical changes of lumbar adjacent segment by comparing
the biomechanics after the surgery of transforaminal lumbar interbody fusion (TLIF) and …

BACKGROUND CONTEXT: Recently, nonfusion pedicle-based dynamic stabilization
systems (PBDSs) have been developed and used in the management of degenerative …

The Dynesys dynamics stabilisation system was developed to maintain the mobility of
motion segment of the lumbar spine in order to reduce the incidence of negative effects at …

Background Two types of screw trajectories are commonly used in lumbar surgery. Both
traditional trajectory (TT) and cortical bone trajectory (CBT) were shown to provide …

Arthrodesis is a recommended treatment in advanced stages of degenerative disc disease.
Despite dynamic fixations were designed to prevent abnormal motions with better …

Background This study aims to compare radiographic and clinical outcomes of Dynesys and
posterior lumbar interbody fusion (PLIF) for the treatment of multisegment disease. Methods …

Posterior nonfusion pedicle‐screw‐based stabilization remains a controversial area of spine
surgery. To date, the Dynesys system remains the most widely implanted posterior …

BACKGROUND: Although posterior lumbar interbody fusion (PLIF) has a successful fusion
rate, the long-term outcome of PLIF is occasionally below expectations because of adjacent …

Dynamic semirigid stabilization of the lumbar spine was introduced in 1994 in an attempt to
overcome the drawbacks of fusion. It is supposed to preserve motion at the treated levels …
