Can Prophylactic Foraminotomy Prevent C5 Palsy

Description

C5 palsy (C5P) is a well-known, although rare complication of cervical spine decompression surgery. In severe forms, C5P causes debilitating upper extremity weakness involving the deltoids and/or biceps brachii muscles, ultimately diminishing these patients' quality of life. Furthermore, about half of patients with C5P present with sensory deficits and/or intractable pain in addition to the muscle weakness. Prophylactic bilateral foraminotomy at the C5 level during cervical decompression surgery has been studied recently with the hope that it will minimize the risk of developing a C5 nerve root palsy postoperatively. Although the current literature provides some support for this claim, there are insufficient data establishing this technique as a proven measure to reduce the incidence of C5P. In the present study, we seek to evaluate the effect of bilateral foraminotomy on postoperative C5P incidence rates. Bilateral foraminotomy has been correlated with a reduced risk of developing C5P following cervical decompression surgery, but an identical foraminotomy procedure has never been applied in a randomized manner to all qualifying patients in a study. Additionally, prophylactic foraminotomy has only been prospectively studied during laminoplasty. In the proposed study, bilateral foraminotomy will be randomized to patients receiving cervical decompression surgery (laminoplasty, laminectomy, fusion). This is a multicenter randomized trial, including the following sites: Cleveland Clinic, Columbia University Medical Center, and University of Southern California Spine Center. Patients undergoing cervical decompression surgery will be consented and enrolled if they meet the inclusion and exclusion criteria. Subsequently, incidence of C5P will be monitored to determine efficacy of prophylactic C5 bilateral foraminotomy during cervical decompression.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • * Cleveland Clinic patients who have been diagnosed with cervical myelopathy, without radiculopathy, and will undergo posterior cervical decompression involving the C4-C5 interspace between 2016 and 2018. This includes patients undergoing cervical laminoplasty and cervical laminectomy and fusion.
  • * Any patient younger than 18 years of age will not be included on the basis of skeletal immaturity. Patients with C5 radiculopathy - defined in our study as the existence of preoperative deltoid muscle weakness in grade 3 or less by MMT - will be excluded. Any patients who have undergone previous cervical spine surgery, or who have any spinal malignancy, trauma or infection will be excluded in order to eliminate the confounding effect of multiple surgical interventions.
