Abstract Background Bony fusion rate was significantly lower in patients with type 3 Modic change than normal endplates. It is not known whether there are relevant differences efficiency among 2 sclerotic or non-sclerotic change, no change. Methods A retrospective study contained 196 lumbar segments 123 subjects undergoing posterior interbody (PLIF) pedicle screw instrumentation (PSI) to assess...

Solid bony fusion of large joints affected with active chronic infections, is still the most effective surgical solution to establish a useful function of the affected limb. Even with extensive peri-articular bone loss and severe deformities, arthrodesis in a functional position can provide effective stability. The reported fusion rates in such patients are not encouraging however, and secondar...

BACKGROUND There have been several imaging studies of cervical radiculopathy, but no three-dimensional (3D) images have shown the path, position, and pathological changes of the cervical nerve roots and spinal root ganglion relative to the cervical bony structure. The objective of this study was to introduce a technique that enables the virtual pathology of the nerve root to be assessed using 3...

Introduction: In contrast to endochondral growth with ossification of a pre-existing cartilaginous matrix, cranial sutures act as intramembranous bone growth sites. New bone is produced at the sutural edges by proliferation of mesenchymal cells and subsequent differentiation into osteoblasts. The suture itself remains in an unossified stage in which maintenance of growth at the osteogenic front...

BACKGROUND Cervical facet dislocation injuries typically present shortly after occurrence due to the pain and neurologic deficit that can be associated with this injury. Bilateral dislocations of the facet joint require prompt evaluation, reduction, and surgical intervention. Rare case reports present bilateral dislocations presenting in a delayed fashion. CASE REPORT We report the case of a ...

BACKGROUND CONTEXT Conditions requiring posterior lumbar spinal fusion remain a clinical challenge. Achieving arthrodesis using autogenous bone graft is inconsistent when rigid internal fixation such as transpedicular instrumentation is applied. Synthetic materials, particularly calcium phosphate-based ceramics, have shown promise for spine fusion applications, especially when combined with aut...

PURPOSE To compare radiographic and clinical outcomes after anterior cervical discectomy in patients with cervical degenerative disc disease using PEEK cages or PMMA spacers with a minimum 1-year follow-up. METHODS Anterior cervical discectomy was performed in 107 patients in one or two levels using empty PEEK cages (51 levels), Sulcem PMMA spacers (49 levels) or Palacos PMMA spacers (41 leve...

STUDY DESIGN A retrospective study. PURPOSE We evaluated the results of the use of anterior debridement and interbody fusion followed by posterior spinal instrumentation. OVERVIEW OF LITERATURE An early diagnosis of pyogenic spondylitis is difficult to obtain. The disease can be treated with various surgical methods (such as anterior debridement and bone graft, anterior instrumentation, and...
