Follow-up of a new titanium cervical plate for fusion of the cervical spine.

ABSTRACT: Cervical plates are in use since the 1990ies for anterior cervical discectomy and fusion (ACDF). The latest step in development was a dynamic plate that allows sliding of the screws facilitating the natural settling of the bone after surgery. We investigated the clinical and radiological results of such a dynamic plate in a patient cohort that underwent single or multi-level ACDF for various cervical degenerative indications, including revision cases, from 2014 to 2019. Clinical and radiological outcome were assessed in 60 eligible patients after a mean of 2.9 years. The assessed neck disability index (NDI), and the visual analogue scale (VAS) of neck and arm pain show comparable results to the literature of ACDF, and specifically other plate designs. Forty-eight Adverse and Serious Adverse Events do not show a link to the product used. Clinical and radiological outcomes of ACDF with dynamic, third generation cervical plates show comparable results to the literature. Careful reporting of all Adverse Events revealed a variety of concomitant diseases, but could not be correlated to the implant used.

Project description:BackgroundAnterior cervical corpectomy and fusion (ACCF) is a standard surgical procedure for cervical spondylosis with spinal cord compression (CSWSCC), especially in patients with intensity on T2-weighted imaging high signal (T2WIHS). The titanium mesh cage (TMC) utilized in this procedure is essential in stabilizing the spine; however, the optimal slotting width of the TMC remains unclear.ObjectiveThis study aimed to investigate the impact of TMC slotting width on the clinical and radiological outcomes of ACCF in patients with spinal cord compression type cervical spondylosis with intensity on T2WIHS (CST2WIHS).MethodsWe retrospectively analyzed 69 patients who underwent single-level ACCF between December 2010 and October 2021. The patients were divided into narrower (< 2 mm) and wider (> 2 mm) groups based on the slotting width of the TMC. The Neck Disability Index (NDI) and Japanese Orthopedic Association (JOA) scores were used to assess clinical outcomes. Radiological outcomes included cervical lordosis (CL), functional spinal unit (FSU) height, transverse decompression range (TDR), spinal canal area (SCA), TMC alignment, and subsidence and fusion rates.ResultsPatients in both groups exhibited significant postoperative improvement in NDI and JOA scores (P < 0.05). Radiologically, patients in the wider slotting group exhibited better decompression, evidenced by a larger TDR (P < 0.01) and smaller postoperative SCA (P < 0.01) than the narrow group. Regarding CL, FSU height, TMC alignment, subsidence, or fusion rates, the groups did not differ significantly. Although statistically non-significant, patients in the wider group exhibited a trend towards improvement in spinal cord signal intensity than those in the narrower group.ConclusionThe study demonstrated that a wider TMC slotting width offers superior decompression and may improve postoperative spinal cord signal; it does not compromise spinal stability or fusion outcomes. These findings indicate that slotting width should be carefully considered in ACCF procedures to optimize decompression and spinal cord recovery.

Project description:Long-term outcome studies are frequently hindered by a decreasing frequency of patient follow-up with the treating surgeon over time. Whether this attrition represents a "loss of faith" in their index surgeon or the realities of a geographically mobile society has never been assessed in a population of patients undergoing spinal surgery. The purpose of this article is to determine the frequency with which patients who have undergone prior surgery and develop new problems attempt to follow-up with their index spine surgeon. The study design was a population survey. All patients seen at two university-based spine centers over a 3-month period were surveyed regarding prior spine surgery. The questionnaire asked details of the previous operation, whether the patient had sought follow-up with their index surgeon, why the patient did not continue treatment with that surgeon, and whether the patient was satisfied with their prior treatment. Sixty-nine patients completed the survey. Prior operations were lumbar (53 patients) and cervical (16). When asked the reason for not seeing their prior surgeon, 10 patients (15%) stated that they (the patient) had moved and 16 (23%) responded that their surgeon no longer practiced in the area. Thirteen (19%) were unhappy with their previous care, 22 (32%) were seeking a second opinion, and 7 (10%) were told they needed more complex surgery. Thirty-seven (54%) discussed their symptoms with their original surgeon before seeking another surgeon. Although 32 patients (46%) had not discussed their new complaints with their index surgeon, only 3 patients (4%) chose not to return to their prior surgeon despite having the opportunity to do so. Forty-nine patients (71%) were satisfied with their prior surgical care, and 42 patients (61%) would undergo the index operation again. Most of the patients seen at the authors' practices after undergoing prior spine surgery elsewhere failed to follow up with their prior spine surgeon for geographical reasons. It appears that the majority of patients who develop new spinal complaints will seek out their treating surgeon when possible. This suggests that patient attrition over long-term follow-up may reflect a geographically mobile population rather than patient dissatisfaction with prior treatment.
