The aim of the study was to investigate the changes of the lumbar intervertebral disc degeneration by magnetic resonance imaging (MRI) after the implantation of interspinous device and the fusion of the adjacent segment. A total of 62 consecutive patients suffering L5/S1 lumbar disc herniation (LDH) with concomitant disc space narrowing or low-grade instability up to 5 mm translational slip in ...

STUDY DESIGN Retrospective cohort study. OBJECTIVE To review the clinical outcome, implant survivorship and reasons for failure after X-Stop implantation. SUMMARY OF BACKGROUND DATA Conflicting data exist concerning clinical outcome of the X-Stop interspinous spacer and little information is being published about implant survivorship and the need for revision surgery. METHODS This retrosp...

Recent studies from Finland reported that maternal pelvic size predicted daughters’ breast and ovarian cancer, possibly because maternal pelvic size is a marker for in utero hormone exposure. We sought to replicate this association in 3845 women born 19151929 in Uppsala, Sweden, and followed from 1960 to 2002. Archived obstetric records provided the standard measures of maternal pelvic size (in...

BACKGROUND One technique in radiofrequency neurotomies uses 2 electrodes that are simultaneously placed to lie parallel to one another. Comparing lesions on cadaveric interspinous ligament tissue and measuring the temperature change in egg white allows us to accurately measure quantitatively the area of the lesion. METHODS Fresh cadaver spinal tissue and egg white tissue were used. A series o...

Purpose: This study aimed to compare the efficacy and safety of stand-alone placement of interspinous spacers (IPS) with decompressive surgery (DS) for the treatment of lumbar spinal stenosis. Methods: Medline, Embase, and the Cochrane Central Register of Controlled Trials databases were searched until February 2016 to identify relevant randomized controlled trials (RCTs) and comparative cohort...

The concept of dynamic stabilisation of the lumbar motion segment using an interspinous device was first introduced by Professor Jacques Sénégas in the 1980s. His original first-generation implant comprised a titanium interspinous process spacer to accommodate load sharing and to limit extension. This was combined with two Dacron bands that controlled flexion movements. In contrast with other f...

The authors hypothesized that the placement of the interspinous implant would show a similar clinical outcome to the posterior lumbar interbody fusion (PLIF) in patients having spinal stenosis with mild segmental instability and that this method would be superior to PLIF without significantly affecting degeneration at the adjacent segments. Forty two adult patients having degenerative spinal st...
