The purpose of this study was to investigate and determine whether there are differences in L5 pedicles morphology between isthmic degenerative L5–S1 spondylolisthesis. One hundred nineteen patients with spondylolisthesis 45 at were enrolled the IS group DS group, respectively, 164 lumbar disc herniation without spondylolysis or classified into normal (NL) group. A series pedicle parameters fif...

Lumbosacral degenerative disc disease is a common cause of lower back and leg pain. Conventional T1-weighted imaging (T1WI) and T2-weighted imaging (T2WI) scans are commonly used to image spinal cord degeneration. However, these modalities are unable to image the entire lumbosacral spinal nerve roots. Thus, in the present study, we assessed the potential of diffusion tensor imaging (DTI) for qu...

Spondylolysis is a defect of the pars interarticularis, eventually causing low back pain. It mostly occurs as a stressfracture, but can be congenital as well. The incidence in the adult Caucasian population is around 6%. It’s more common in males then in females [1]. Young athletes are most vulnerable, especially in sports requiring repetitive hyperextension and rotational loading: gymnasts, fo...

A 79-year-old woman was seen due to low back pain and severe right hip pain. The pain was radiating to the right calf. The patient reported numbness of her right ankle and toes. On detailed questioning, she reported that her hip pain worsened with sitting and walking. She stated that her hip pain improved when lying supine. Her medical history revealed hypertension and osteomalacia, but no trau...

STUDY DESIGN  Systematic literature review. RATIONALE  Many authors have postulated on various risk factors associated with the pathogenesis of degenerative spondylolisthesis (DS), yet controversies regarding those risk factors still exist. OBJECTIVE  To critically appraise and summarize evidence on risk factors for DS. METHODS  Articles published before October 15, 2011, were systematica...

Multilevel lumbar fusion usually requires a large quantity of iliac crest bone graft but the supply is usually insufficient, so an alternative bone graft substitute for autograft is needed. This prospective study investigated the efficacy of calcium sulfate by comparing the fusion rates between the experimental material (calcium sulfate pellets with bone chips from laminectomy) and autologous i...

We analysed the complications encountered in 102 consecutive patients who had posterolateral lumbosacral fusion performed with transpedicular screw and rod fixation for non-traumatic disorders after a minimum of two years. Of these, 40 had spondylolysis and spondylolisthesis, 42 a degenerative disorder, 14 instability after previous laminectomy and decompression, and six pain after nonunion of ...

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 C1 and C2 v...

Spondylolisthesis is a common condition that can be managed both nonsurgically and surgically. More than 80% of children treated nonsurgically have resolution of symptoms. For those patients requiring surgical treatment, fusion in situ may provide adequate treatment for young patients. Patients with neural compression may require decompression to relieve symptoms, and fusion is also usually ind...

Lumbar spondylolysis and spondylolisthesis are common spinal disorders that most of the times are incidental findings or respond favorably to conservative treatment. In a small percentage of the patients, surgical intervention becomes necessary. Because too much attention has been paid to novel surgical techniques and new modern spinal implants, some of fundamental concepts have been forgotten....
