STUDY DESIGN Retrospective analysis of prospectively collected clinical data. OBJECTIVE To assess the long-term outcome of patients with monosegmental L4/5 degenerative spondylolisthesis treated with the dynamic Dynesys device. SUMMARY OF BACKGROUND DATA The Dynesys system has been used as a semirigid, lumbar dorsal pedicular stabilization device since 1994. Good short-term results have bee...

Traumatic lumbar spondylolisthesis is a rare lesion and frequently noted in patients with multiple traumatic injuries. We report one case of L5 traumatic spondylolisthesis, which obtained successful decompression, reduction, interbody fusion and fixation by posterior lumbar interbody fusion, and got satisfactory outcome. We recommend early decompression, reduction, interbody fusion and fixation...

The patient was a 32-year-old woman diagnosed with grade III spondylolisthesis at the age of 18. While the patient had not experienced back pain in recent years, she anticipated a recurrence of symptoms during her final trimester of pregnancy. Lumbar magnetic resonance imaging was used to confirm the presence of grade IV spondylolisthesis. J Orthop Sports Phys Ther 2010;40(5):324. doi:10.2519/j...

A 14-year-old boy presented with symptomatic high-grade dysplastic type spondylolisthesis, with a presence of spina bifida occulta, not diagnosed by plain radiographs, but confirmed on preoperative CT and MR. Circumferential fusion with partial reduction of L5/S1 was performed. Awareness of the coexistence of spondylolisthesis and spina bifida by an accurate preoperative planning is paramount t...

Spondylolisthesis consists of the slippage of a vertebra in relation to the one beneath. It is caused by separation of the neural arch from the vertebral body (spondylolysis), and predominantly occurs at the isthmus (pars interarticularis). Originally thought to be a congenital anomaly, its strict correlation with certain activities that seem to exert stress on lower spine was later demonstrate...

Most unilateral pedicle stress fractures occur on the contralateral side of patients with unilateral spondylolysis. However, there are few reports of unilateral pedicle stress fractures in patients with bilateral spondylolysis and spondylolisthesis. We report a unique case of unilateral pedicle stress fracture in a long-term hemodialysis patient with isthmic spondylolisthesis. A 65-year-old man...

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...

Purpose: Over 170 years ago, traumatic spondylolisthesis of the axis or hangman’s fracture was described. Most descriptions of this entity have focused on adult presentations. Methods: We review the literature on pediatric cases of hangman’s fracture emphasizing the embryological as well as presentation aspects. Results: The majority of cervical spine fractures in children occur at C 1 and C 2 ...
