AI Article Synopsis

  • This study compares the effectiveness of 3D-printed artificial discs (CADR) versus anterior cervical discectomy and fusion (ACDF) in treating cervical spondylosis in 73 patients.
  • Both methods showed significant improvement in clinical symptoms, but CADR resulted in better postoperative range of motion (ROM) and fewer adverse effects.
  • The findings suggest that 3D-printed artificial discs provide a safer and more effective treatment option, with less blood loss and a lower incidence of additional surgery for complications compared to ACDF.

Article Abstract

Purpose: To compare the clinical efficacy of 3D-printed artificial discs with that of ACDF for treating cervical spondylosis.

Methods: This was a retrospective analysis of 73 patients with single-level cervical spondylosis who met the inclusion criteria between January 2020 and December 2022 at XX Hospital. The patients were divided: 38 patients in the ACDF group and 35 patients in the CADR group. Patient general information, including operation time and intraoperative blood loss, was collected. The clinical effect of the combination therapy was evaluated by the VAS, JOA, and NDI. The radiological effect was evaluated using the ROM test. Ethics No. 201,606,009.

Results: The average follow-up times in the ACDF and CADR groups were 28.24 ± 4.65 and 29.11 ± 5.06 months, respectively (P = 0.443). Clinical symptoms (evaluated by VAS, NDI, and JOA) are significantly improved in both the ACDF and CADR groups with similar efficacy. The preoperative ROM of the ACDF group was 40.03 ± 8.79, while that of the CADR group was 42.11 ± 7.98 (P = 0.293). However, the postoperative ROM in the ACDF group was 35.29 ± 7.23, which was lower than that in the CADR group (40.43 ± 6.98) (P = 0.003). Furthermore, only one patient in the ACDF group experienced mild dysphagia after surgery, and the patient recovered within three days. ASD occurred in nine patients in the ACDF group and in two patients in the CADR group (Χ²=4.597, P = 0.032).

Conclusions: Compared with ACDF, 3D-printed artificial discs for treating single-level cervical spondylosis have proven to be clinically effective; it associated with less blood loss and a lower incidence of ASD, and maintain a better cervical ROM.

Cervical spondylotic myelopathy (CSM) is a neurological disorder characterized by degenerative changes in the spinal cord and compression of the spinal cord and its adjacent structures due to various reasons, such as intervertebral disc herniation. The Japan Orthopaedic Association score is a disease-specific outcome tool that provides quantitative measurements for CSM patients. At present, no scholars have developed a model that can directly predict the prognosis of CSM patients.

Background: C5 palsy is a frequent complication following cervical spine surgery, particularly after posterior approaches. Although several risk factors have been proposed, the incidence of C5 palsy after anterior cervical discectomy and fusion (ACDF) remains less well understood. This study aims to elucidate the risk factors and neurological recovery associated with C5 palsy following ACDF.

Objective: To compare the effectiveness of different measurement methods on bone miner density (BMD), including cervical HU of CT, MRI-based cervical vertebral bone quality (C-VBQ), and value of DEXA, for predicting cage subsidence after single-level ACDF.

Methods: This is a retrospective study, and patients who underwent single-level ACDF from June 2019 to June 2022 were recruited. We collected preoperative total segmental vertebral height (pre-TSVH), cage subsidence height, cervical angle (CA), T1-slope, straight or reverse cervical curvature, mean HU value of C3-7 (C-HU), mean HU of segment (seg-HU), C-VBQ, segmental C-VBQ (seg-VBQ), and total lumbar value ( value).

Does two-level hybrid surgery promote early fusion compared with two-level anterior cervical discectomy and fusion?

Spine J

December 2024

Department of Orthopedics, Orthopedic Research Institute, West China Hospital, Sichuan University, Chengdu, China. Electronic address:

Background Context: Hybrid surgery (HS), which involves both anterior cervical discectomy and fusion (ACDF) and cervical disc replacement (ACDR), is increasingly used to treat multilevel cervical disc degenerative disease, yielding satisfactory clinical outcomes. Early fusion is critical after anterior cervical fusion surgeries, but there are no studies comparing the rate of early fusion of HS with that of ACDF.

Purpose: The purpose of this study was to compare the rate of early fusion (3-6 months postoperatively) of two-level HS with that of two-level ACDF surgery.
