Clinical effects of the bridge-type ROI-C interbody fusion cage system in the treatment of cervical spondylosis with osteoporosis

Abstract

ObjectiveTo investigate the early and mid-term efficacy and safety of the bridge-type ROI-C interbody fusion cage system in the treatment of cervical spondylosis with osteoporosis during anterior cervical discectomy and fusion (ACDF).Patients and methodsThe clinical data from 24 cervical spondylosis patients with osteoporosis treated with ACDF were retrospectively analyzed. All patients were treated with ROI-C cage. Double-energy X-ray absorptiometry (DEXA) was used to measure the bone mineral density (BMD). The cervical sagittal radiographic parameters were measured and compared using X-ray including C2–C7 Cobb angle, segmental angle (SA), cervical vertebral bow depth, and height of operation segment (HOS). Postoperative dysphagia was recorded according to the Bazaz score. The Japanese Orthopedic Association (JOA) scores and Neck Disability Index (NDI) scores were used to evaluate the clinical outcomes at different time points. Odom and Vaccaro criteria were used to assess the surgical effects and to evaluate the fusion of the bone graft.ResultsThe mean duration of the postoperative follow-up was 27.4±5.7 months (ranging from 21 to 36 months). The JOA scores and NDI scores at 3 months post operation and at the time of final follow-up were significantly different from those before surgery (P<0.05). Two patients had mild dysphagia after surgery, but it disappeared after symptomatic treatment for 3–5 days. Sagittal radiographic outcomes were significantly improved at 3 months post operation (P<0.05). At the time of final follow-up, the radiographic parameters were well maintained and were not significantly different compared with 3 months post operation (P>0.05).ConclusionThe ROI-C cage system is safe and effective for use in patients undergoing anterior cervical spondylosis surgery for osteoporosis treatment. It results in a positive effect on bone graft fusion, is able to effectively improve cervical curvature, restores intervertebral height, and reduces the incidence of postoperative dysphagia. The clinical effects were positive at the early and middle postoperative stages.

Comparing the Bridge‐Type Zero‐Profile Anchored Spacer (ROI‐C) Interbody Fusion Cage System and Anterior Cervical Discectomy and Fusion (ACDF) with Plating and Cage System in Cervical Spondylotic Myelopathy

“…Cervical spondylotic myelopathy (CSM) is the most common progressive degenerative disease of the spine among the geriatric population 1,2 . Cervical spondylosis generally begins with degenerative alterations in the disk space causing secondary changes in the surrounding soft tissue and bony structures, which leads to progressive narrowing of the spinal canal, followed by subsequent compression of the dural sac, resulting in neurologic symptoms like hypaesthesia and muscle weakness 3 . Common conservative treatment methods include drug therapy, neck brace protection and traction therapy.…”

However, these treatments are not effective for severe CSM, which can lead to spinal cord dysfunction and significantly reduce patients' quality of life.…”

<p>Cervical intradural disc herniation with Brown-Séquard syndrome: case report and literature review</p>

“…From previous reports, anterior bone graft fusion appears to be superior to posterior decompression (Table 1). Anterior discectomy is the preferred treatment because it directly addresses the problem 43. Vertebral resection may be required depending on the size and location of the compressed disc fragments and the degree of adhesion between the dura and the posterior longitudinal ligament.…”

Preliminary outcomes of allograft and hydroxyapatite as substitutes for autograft in anterior cervical discectomy and fusion with self-locking standalone cages

“…A C-arm X-ray machine was used to locate the cervical segment of the lesion, and the corresponding intervertebral space was opened and completely decompressed. After the cartilage endplate was treated, an appropriate type of zero notch self-stability cervical fusion cage (ROI-C) was placed into the decompressed intervertebral space, fixed by double anchoring wings [ 29 ]. Patients would wear the cervical for most of time when they got up for the first 2 weeks, and they wear it only when they are outdoors in the next 4–6 weeks.…”
