Expansive cervical laminoplasty began its evolution in the 1970s in Japan for the treatment of cervical spondylotic myelopathy secondary to ossification of posterior longitudinal ligament or cervical spondylosis. The goal of the procedure is to reduce the complications associated with the inherent destabilization associated with laminectomy while preserving cervical spine range of motion [1]. I...

Interspinous spacers were developed to treat local deformities such as degenerative spondylolisthesis. To treat patients with chronic instability, posterior pedicle fixation and rod-based dynamic stabilization systems were developed as alternatives to fusion surgeries. Dynamic stabilization is the future of spinal surgery, and in the near future, we will be able to see the development of new de...

ISP fixation has been shown to be a safe and efficacious alternative to traditional methods of posterior spinal fixation. A high degree of biomechanical stability and reliable fusion rates are achieved with preservation of adjacent level structures when using new iterations of rigid interspinous fixation. Since ISP devices do not violate adjacent facet joints, they potentially can decrease the ...

The authors describe a 48-year-old woman suffering from bilateral upper-extremity numbness and axial radiating pain. Magnetic resonance imaging revealed soft-tissue edema and enhancement surrounding the dorsal tip of the C7 spinous process. Excisional biopsy of the lesion revealed a mildly inflamed bursa, with no evidence of an active infection. Removal of the inflamed bursa resulted in complet...

A 62-year-old woman presented with 4 months of neck, shoulder, and hip pain, morning stiffness, and elevated inflammatory markers compatible with polymyalgia rheumatica (PMR). Cervical spine imaging demonstrated ill-defined enhancement in posterior neck soft tissues (figure 1), consistent with interspinous bursitis. She reported right-sided headache. Brain magnetic resonance angiography demonst...

The diagnosis of transverse spinal fractures in patients with ankylosing spondylitis and Forestier's disease (DISH) may be difficult. The MRI features of 9 such fractures at the disk, vertebral body, spinal canal and posterior elements are presented. Fractures of the posterior elements (posterior arch fractures and/or rupture of interspinous or supraspinous ligaments and contiguous soft tissue ...
