Clinical Implementation of Tissue-Sparing Posterior Cervical Fusion: Addressing Market Access Challenges.

The traditional open midline posterior cervical spine fusion procedure has several shortcomings. It can cause soft tissue damage, muscle atrophy, compromise of the lateral masses and painful prominent posterior cervical instrumentation or spinous process if there is dehiscence of the fascia. Additionally, patients frequently experience the rapid development of adjacent segment disease, which can result in the reemergence of debilitating pain and functional impairment.

Perioperative and safety outcomes following tissue-sparing posterior cervical fusion to revise a pseudarthrosis: A multicenter retrospective review of 150 cases.

Background: Posterior cervical fusion (PCF) with lateral mass screws is a favorable treatment option to revise a symptomatic pseudarthrosis due to reliable rates of arthrodesis; however, this technique introduces elevated risk for wound infection and hospital readmission. A tissue-sparing PCF approach involving facet fixation instrumentation reduces the rates of postoperative complications while stabilizing the symptomatic level to achieve arthrodesis; however, these outcomes have been limited to small study cohorts from individual surgeons commonly with mixed indications for treatment.

Materials And Methods: One hundred and fifty cases were identified from a retrospective chart review performed by seven surgeons across six sites in the United States.

Long-term outcomes in patients treated with tissue-sparing posterior cervical fusion to revise a 1-level pseudarthrosis following ACDF.

Study Design: Observational Study BACKGROUND: Symptomatic pseudarthrosis is one long-term complication in patients treated with anterior discectomy and fusion (ACDF). When revising a pseudarthrosis, a surgeon must decide to intervene posteriorly and/or anteriorly. Open posterior cervical fusion (PCF) is attractive for high rates of arthrodesis, however this technique introduces risks of added complications resulting from extensive soft tissue dissection.

Length of stay associated with posterior cervical fusion with intervertebral cages: experience from a device registry.

Background: Using a multi-center medical device registry, we prospectively collected a set of perioperative and clinical outcomes among patients treated with tissue-sparing, posteriorly-placed intervertebral cage fusion used in the management of symptomatic, degenerative neural compressive disorders of the cervical spine.

Methods: Cervical fusion utilizing posteriorly-placed intervertebral cages offers a tissue-sparing alternative to traditional instrumentation for the treatment of symptomatic cervical radiculopathy. A registry was established to prospectively collect perioperative and clinical data in a real-world clinical practice setting for patients treated via this approach.

Perioperative complications in patients treated with posterior cervical fusion and bilateral cages.

Context: Posterior cervical cages have recently become available as an alternative to lateral mass fixation in patients undergoing cervical spine surgery.

Aims: The purpose of this study was to quantify the perioperative complications associated with cervical decompression and fusion in patients treated with a posterior cervical fusion (PCF) and bilateral cages.

Settings And Design: A retrospective, multicenter review of prospectively collected data was performed at 11 US centers.

Anterior Cervical Pseudarthrosis Treated with Bilateral Posterior Cervical Cages.

Background: Pseudarthrosis after anterior cervical discectomy and fusion (ACDF) causes persistent pain and related disability. Posterior revision surgery results in higher healing rates, but is more extensive compared to anterior surgery.

Objective: To evaluate minimally disruptive, tissue sparing posterior fusion via bilateral placement of posterior cages between the facet joints as an alternative treatment option.

Novel instrumentation and technique for tissue sparing posterior cervical fusion.

Authors have developed a simple, disposable instrument set for posterior cervical fusion (PCF). The instruments and technique minimize soft tissue disruption and facilitate access for cervical facet joint cartilage decortication. Technique is proposed for select patients not requiring laminectomy.

Percutaneous posterior cervical fusion with the DTRAX Facet System for single-level radiculopathy: results in 60 patients.

Object: The authors present 1-year results in 60 patients with cervical radiculopathy due to spondylosis and stenosis that was treated with a bilateral percutaneous facet implant. The implant consists of a screw and washer that distracts and immobilizes the cervical facet for root decompression and fusion. Clinical and radiological results are analyzed.
