Laminectomy for Cervical Spondylotic Myelopathy

Posterior cervical decompression has been available as a treatment option for cervical spondylotic myelopathy since the 1940s. Patients may present with axial neck pain, radiculopathy, myelopathy, or a combination of these symptoms. The natural history of cervical spondylotic myelopathy is generally defined by slow, progressive deterioration. Posterior surgical options include multilevel laminectomy and fusion or laminoplasty. Laminectomy without fusion has also been extensively used in the past, but is less commonly used now because of a high rate of postoperative complications. The choice of posterior procedure is based on multiple factors, including the severity of disease and levels of compression, the presence of degenerative changes, preoperative sagittal alignment, instability, and other patient factors.

Congratulations to our 2017 Senior Achievement Award and Achievement Award Winners!

Active volunteer involvement is at the heart of AAOS activities. Our meetings, courses, educational materials, clinical practice guidelines, and advocacy efforts are just a few of the many activities that depend on participation by volunteers for their success. Volunteers are vital—not only to the AAOS, but also to orthopaedic specialty societies; national, state, and local orthopaedic societies; and the broader medical community.

Complications of Spine Surgery: Neurodeficits of the Spinal Cord and Nerve Roots

Neurodeficits associated with spinal cord injury may arise intraoperatively or postoperatively. Such neurologic complications are classified by the American Spinal Injury Association (ASIA) based on lesion type and affected motor and/or sensory function. Epidural hematomas are among the most common postsurgical complication; rarer complications include epidural abscesses, pseudomeningoceles, and cauda equina syndrome. Singh addresses spinal cord syndromes, mechanisms of injury, and specific insults to nerve roots that can result from spine surgery, including complications related to instrumentation. In assessing for possible postoperative injury, careful patient evaluation in the post-anesthesia care unit is essential. Although steroid therapy for management of acute spinal cord injuries is recommended according to specified guidelines, the use of corticosteroids (methylprednisolone) nevertheless remains controversial. This article also provides a discussion on the modalities of intraoperative monitoring, including somatosensory-evoked potentials, motor-evoked potentials, and stimulated electromyography, which can aid in the prevention of spinal cord and nerve root injuries.
