Prof. Li Zhongshi's speech

Professor Li Zhongshi delivered a speech, saying that although artificial disc replacement has been popular for more than 20 years, it is still a new thing in history, and because of the limitations in its development, all aspects need to be studied in depth. Through unremitting efforts, the special committee has successfully established its brand image and achieved excellent results. We hope that experts in related fields, led by Professor Liu Hao, will actively carry out various tasks, play a leading and promoting role, promote academic exchanges, standardise consensus guidelines, and make a Chinese voice for the academic community.

Prof. Xu Lin's speech

In his speech, Prof. Xu Lin thanked for the invitation and expressed his congratulations on behalf of the Chinese Society of Rehabilitation Medicine on the success of the conference. Replacement surgery, which is controversial and bottlenecked, is not only an important direction for the development of spinal surgery, but also a critical developmental juncture. The conference was a milestone event across the ages, recalling the stormy changes in the development of orthopaedics in China, the historical dedication of the old experts and the future of the young talents, and he stressed that practice is the only test of truth.

Professor Liu Hao's speech

In his speech, Professor Liu Hao emphasised the importance of popularising science and technology and the cultivation of talent, the increasing incidence of cervical spondylosis in recent years, the declining age of patients and the significant increase in the number of operations. To better meet these challenges, we need to bring together the experiences and perspectives of all. He hoped that the young staff would work more and actively carry out thematic case discussions and academic exchange activities in order to enhance their capacity for independent innovation in surgical operations, clinical rehabilitation and industry-academia-research development, so that they could jointly meet the challenges and achieve even better results.

Special presentations

Experts at the conference conducted in-depth discussions and research on the treatment, surgery and rehabilitation of cervical spondylosis, which provided important references and guidance for clinical practice.

The Chinese Contribution of Non-Fusion Technology in the Spine

Non-fusion technology of the spine can effectively restore the physiological forward flexion of the cervical spine and preserve the mobility of the non-fused segment; it has obvious advantages in maintaining the mobility of the cervical spine and its impact on the mobility of the adjacent segments; there are few biomechanical and clinical studies on Hybrid surgery, the clinical evidence level is low, and the intermediate and late results of Hybrid surgery need to be further observed.

The 18-Year Path of Exploring Artificial Cervical Discs in West China

Based on 18 years of experience, Prof. Liu has a few points to re-understand about ACDR - was ACDR introduced to replace ACDF and slow down the degeneration of the adjacent segment?

Can artificial cervical disc replacement be performed for severe degenerative cervical spondylosis?

CTDR can be applied to the treatment of a proportion of patients with severe degenerative cervical spondylosis; combined with relevant surgical techniques, CTDR can effectively restore interbody height, physiological curvature and mobility; correct postoperative functional exercises can achieve better clinical outcomes; it is an optional surgical procedure under the premise of good communication with patients and their families; follow-up of long-term efficacy period in large cases has yet to be accumulated.

Case sharing on Mobi-C artificial cervical disc replacement

Professor Li concludes with a thought: how much does heterotopic ossification affect the outcome after ACDR? With the increasing variety of prostheses available, more experience has been gained recommending no more than three artificial cervical disc prostheses for replacement. There are currently only two FDA-approved prostheses for two-segment disc replacement, and artificial cervical disc replacement is still on the way, with the hope that more bionic artificial cervical disc prostheses will soon be available.

Analysis of the reasons for the "coldness" of artificial cervical discs

Cervical artificial disc replacement is no worse than anterior cervical fusion surgery in terms of post-operative recovery, overall treatment outcome, and other post-operative complications such as degeneration of adjacent segments, swallowing difficulties and secondary surgery. Heterotopic ossification remains the most important long-term follow-up complication after cervical artificial disc replacement, and its occurrence influences the initial choice of surgery. The types of artificial discs available, expected clinical outcomes, indications, surgical technique, and surgical efficiency are the main reasons for the current decline in the number of cervical artificial disc procedures.

Will double-segment artificial disc replacement become mainstream?

Thorough decompression and fine intervertebral management are prerequisites for good implantation; ideal/acceptable indications for artificial disc replacement based on the Chinese population need to be explored in the future; evidence-based health economics needs to be improved.

Why are we doing less and less artificial discs in the cervical spine?

Professor Liu summarised the following five points after reflection: long-term follow-up showed that the reoperation rate of CDR is lower than that of ACDF; optimisation of prosthesis design and surgical protocol should reduce the incidence of HO and spontaneous fusion; optimised CDR prosthesis and surgery should better preserve the motion of the cervical spine; long-term follow-up showed that CDR surgery or overall satisfaction is higher than that of ACDF; CDR surgery with strict control of indications still has a broad The clinical application of CDR surgery is still promising.

Evidence-based Cervical Artificial Disc Replacement

CDA and ACDF in a 10-year retrospective: single-segment CDA: no difference in long-term outcome from ACDF; dual-segment CDA: significantly lower long-term revision rate than ACDF; high incidence of HO in CDA but no impact on functional scores; CDA or ACDF: need to consider physician factors, patient factors, etc.
