Impact of Posterior Cervical Foraminotomy Before or After Cervical Disk Replacement: Current Evidence
1Department of Orthopaedic Surgery, Vanderbilt University Medical Center, Nashville, TN.
Study Design:
Narrative review.
Objectives:
The purpose of this study was to provide a review of the current evidence on the impact of posterior cervical foraminotomy (PCF) performed before or after cervical disk replacement (CDR).
Summary Of Background Data:
The impact of PCF on outcomes in the setting of CDR is an evolving field, given the recent widespread adoption of CDR and the relative rarity of patients who have undergone both procedures.
Methods:
A literature search was conducted using PubMed to determine current evidence regarding the indications, outcomes, and biomechanical effects of CDR and PCF when performed alone or in combination.
Results:
When radicular symptoms persist following PCF, a CDR can be safely performed to provide further decompression. Conversely, a PCF can be safely performed following CDR for these same indications. The biomechanical effects of these procedures in combination demonstrate maintained stability when the facetectomy is less than 50% of the facet joint. Studies demonstrate that stability is not significantly decreased by the presence, amount, or level of posterior foraminotomies in the setting of CDR.
Conclusions:
A PCF can be safely performed before or after cervical disk arthroplasty for recurrent radicular symptoms.
Level Of Evidence:
Level V.
