Intrathecal baclofen therapy is a highly effective treatment option for patients with medically refractory spasticity. The catheter, pump, and wound are subject to numerous complications both at the time of implantation and throughout the life of the implanted system. Careful technique, close observation, and aggressive evaluation and correction of problems can reduce the incidence and severity of the complications when they occur.

The past several decades have been the setting for a remarkable evolution of spinal instrumentation technology. The advancements that have been made have allowed previously complex disorders of the cervical spine, the atlantoaxial articulation, and the occipitocervical junction to be managed more effectively with direct methods of internal fixation and arthrodesis. This has resulted in improvements in patient outcomes and fusion success rates. The improved strength of instrumentation constructs allows minimal, if any, external bracing, obviating the need for a halo orthosis in many cases. In this paper the authors review key events that have occurred in neuroimaging, biomechanical testing, and the development of fusion and instrumentation constructs.

Object. Management of infection in the hardware system—fixated spine has proven to be problematic. In many cases, instrumentation is required to provide stability or to maintain correction of deformity, and removal could be hazardous. The authors describe the use of closed continuous irrigation to treat spinal wound infections in patients with fixation systems; irrigation can be used in all parts of the spine with excellent results. Methods. The authors conducted a retrospective chart-based review of cases in which spinal instrumentation procedures were performed consecutively during a 10-year period. Infection developed in 36 patients. The infections involved the cervical, thoracic or thoracolumbar, and lumbar regions. Anterior and posterior drains were placed in one patient. In one patient refractory infections responded to replacement of the dual-inflow port drainage system. In all cases the wound infection completely resolved. There were no cases that required the removal of the fusion mass or instrumentation. In all cases progression to solid fusion was achieved. Conclusions. Closed irrigation systems can be used effectively to manage anterior or posterior cervical, thoracic, and lumbar wound infections. These systems preclude the explantation of the instrumentation and allow spinal stability to be preserved. The authors noted no evidence of recurrent infection or failed fusion.

Hemostatic options available to the surgeon in the late 19th and early 20th centuries were limited. The surgical ligature was limited in value to the neurological surgeon because of the unique structural composition of brain tissue as well as the approaches and operating angles used in this type of surgery. In this manuscript the authors review the options available and the evolution of surgical hemostatic techniques and electrosurgery in the late 19th and early 20th centuries and the impact of these methods on the surgical management of tumors of the brain and its coverings.

Study DesignA literature review.Purpose To explore the utility of laminoplasty in combination with instrumented fusion, with a focus on neurological outcomes and changes in kyphotic deformity.Overview of LiteratureManagement of cervical spondylotic myelopathy (CSM) to reduce morbidity within the neurosurgical population.MethodsA US National Library of Medicine PubMed search was conducted for manuscripts pertaining to cervical laminoplasty and fusion for the management of CSM. Several relevant studies were shortlisted for review, and the bibliographies of the articles were searched for additional references. The search was limited to human studies, English-language literature, and reports on more than one patient.ResultsCombined laminoplasty and fusion was found to provide at least comparable, if not superior, neurological outcomes in specific patient populations with CSM. The Japanese Orthopedic Association scores, local kyphosis, and C2–C7 angle have been reviewed in several manuscripts, and improvement in each of these categories was found with laminoplasty and fusion.ConclusionsThe treatment of CSM necessitates an individualized approach based on the pathoanatomical variation. Laminoplasty and fusion can be appropriately used for patients with CSM in a setting of local kyphotic deformity, ossification of the posterior longitudinal ligament, associated segmental instability, and the need for strong stabilization.
