Unilateral pedicle stress fracture accompanying spondylolytic spondylolisthesis is rare even in the elderly. Most are associated with major trauma, previous spine surgery, or stress-related activity. Here, the authors describe an unique case of unilateral pedicle fracture associated with spondylolytic spondylolisthesis at the L5 level, which was successfully treated by posterior lumbar interbod...

Introduction The incidence of degenerative osteoarthritis of the hip or knee joint and degenerative changes in the lumbar spine both increased with age. It was reported that lumbar lordosis and sacral inclination were related to the degree of extension of the hip, there may be an associated loss of lumbar lordosis. Many patients also have degenerative changes of the knee with loss of extension ...

We report a case of rare cervical isthmic spondylolisthesis of C6-7 combined occult spinal bifida at C6, and review the radiologic finding, different diagnosis and treatment. A 23-year old female presented nuchal, back pain after traffic accident. Radiologic finding showed the 6(th) cervical isthmic defect, spondylolisthesis and dysplasia. The patient was conservatively treated about 8 weeks, a...

High-grade dysplastic spondylolisthesis is extremely rare and always involves the L5-S1 level. It is attributed to congenital dysplasia of the superior articular process of the sacrum. It can remain asymptomatic for a long time and can progress to a more severe grade of olisthesis and spondyloptosis. Surgical treatment has varied from posterior-only in situ fusion to anterior and posterior fusi...

A system is presented for the analysis of failure after spinal operations: 1) outright failure; 2) temporary relief; 3) failure in spondylolisthesis; and 4) infections. With this system it is possible to trace the causes of failure and to correct some of them. When they are used as a guide before operation, the recommendations made should help to prevent many failures.

BACKGROUND Early stages of scoliosis and spondylolisthesis entail changes in the intervertebral disc (IVD) structure and biochemistry. The current clinical use of MR T2-weighted images is limited to visual inspection. Our hypothesis is that the distribution of the MRI signal intensity within the IVD in T2-weighted images depends on the spinal pathology and on its severity. Therefore, this study...

A systematic review of the literature was performed to establish whether direct repair of the pars defect or intervertebral fusion achieves better Oswestry Disability Index scores in adolescent spondylolysis or low-grade spondylolisthesis. Nine studies fulfilled the inclusion criteria, reporting a minimum total of 80 direct repairs and 108 fusions because of presumed replication of data between...

A patient with Rubinstein-Taybi syndrome complicated by tetraplegia secondary to cervical spondylolisthesis is reported. The abnormalities presenting in this condition are reviewed.
