Background: The pathogenesis of cervical spondylotic is degenerative changes of the cervical intervertebral disc, or bone hyperplasia of the posterior and hook joints, and instability of the joints of the cervical vertebrae. It causes the nerve roots to be stimulated and oppressed. The clinical manifestations are the sensation, movement, and reflex disorder of the cervical spinal nerve roots that are stimulated and oppressed, especially the numbness and pain of the neck, shoulders, upper limbs, and fingers. In this systematic review, we aimed to evaluate the efficacy and safety of acupuncture and chiropractic in the treatment of cervical spondylotic. Methods and analysis: We will search for PubMed, Cochrane Library, AMED, Embase, WorldSciNet; Nature, Science online and China Journal Full-text Database (CNKI), China Biomedical Literature CD-ROM Database (CBM), and related randomized controlled trials included in the China Resources Database. The time is limited from the construction of the library to September 2019. We will use the criteria provided by Cochrane 5.1.0 for quality assessment and risk assessment of the included studies, and use the RevMan 5.3 and Stata 13.0 software for meta-analysis of the effectiveness, recurrence rate, and symptom scores of cervical spondylotic. Ethics and dissemination: This systematic review will evaluate the efficacy and safety of acupuncture and chiropractic for cervical spondylotic. Because all of the data used in this systematic review and meta-analysis have been published, this review does not require ethical approval. Furthermore, all data will be analyzed anonymously during the review process trial.

Background: The incidence of proximal humeral fracture is increasing gradually. Many patients choose open reduction and internal fixation. With the maturity of surgical technology and thought, people begin to think about the optimization of surgical effect from the surgical incision, including less trauma, less bleeding, less postoperative complications and fast postoperative recovery. However, due to the complexity of shoulder anatomy, scholars have created different surgical approaches from different perspectives. Objective: Although the effect of open reduction and internal fixation is confirmed, there are still some differences in the effect of different surgical approaches. We need to study the summary and research progress of surgical approach for proximal humeral fracture, which is conducive to the selection of the optimal approach for incision, so as to improve the prognosis. Method: Selective literature review. Result: At present, common surgical approaches include lateral approach, anteromedial approach, anterolateral approach, small incision approach and other approaches. This paper describes and compares the advantages and disadvantages of each approach, so as to choose the best approach for different fracture types. Conclusion: Based on the complexity of the anatomical relationship of the shoulder joint, the displacement, classification of the fracture, the proximal humerus are opened and exposed from different perspectives. Choosing a safe surgical approach is one of the key links of the whole operation and plays an important role in the postoperative effect. In this paper, the common approaches and new approaches of open reduction and internal fixation for proximal humeral fracture are reviewed, which provides new ideas for the design of surgical scheme.
