Objective To investigate the development and appl ication of the computer aided surgery systems in the joint surgery field. Methods The l iteratures were extensively reviewed to analysis the usefulness of current active, semi-active and passive computer aided surgery systems in solving the cl inical problems of joint surgery. Results Several computer aided surgery systems have met the high technique demands, such as the precision of anatomical position and orientation, the accuracy of normal l imb al ignment restoration, the optimum of instrumentation control in arthroplasty, peri-articular osteotomy and minimally invasive procedure. Conclusion Computer aided joint surgery systems facil itate precise surgical techniques to achieve ideal operative outcome.
ObjectiveTo summarize the application status of three-dimensional (3-D) printing technique in joint surgery and look forward to the future research directions. MethodsThe recent original articles about the application and research of 3-D printing technique in joint surgery were extensively reviewed and analyzed. ResultsIn clinical applications, 3-D printing technique can provide "tailored" treatment and custom implants for patients, which helps doctors to perform the complex operations easier and more safely; in fundamental research, tissue engineered scaffolds with desirable external shape and internal organization are easily fabricated with 3-D printing technique, which can meet the demand of cell adherence and proliferation. Even more, cells may be deposited with the biomaterials during the printing. ConclusionWith the development of medical imaging, digital medicine and new materials, 3-D printing technique will have a wider range of applications in joint surgery.
Objective To explore the nursing quality standards of joint surgery based on “structure-process-outcome” three-dimensional quality evaluation model, and provide a reference for improving the quality of joint surgery nursing. Methods From March to July 2023, based on the “structure-process-outcome” three-dimensional quality structure model as the theoretical framework, combined with systematic literature review and semi-structured interviews, the quality standards of joint surgery specialist nursing were preliminarily formulated. The Delphi method was used for screening, demonstration, and correction, then the analytic hierarchy process was used to determine the weights. Results The recovery rates of the two rounds of expert letter consultation were 93.75% and 100.00%, respectively. The expert authority coefficients of both rounds were 0.95. The positive coefficients of experts in the two rounds were 0.93 and 1.00, respectively. The coefficients of variation after the second round of correspondence were 0-0.20. In the second round of correspondence inquiry, the Kendall harmony coefficients of primary standards, secondary standards and tertiary standards were 0.156, 0.115 and 0.285, respectively, with statistical significance (P<0.05). Finally, the quality standards of joint specialty nursing included 3 primary standards, 23 secondary standards and 99 tertiary standards. Conclusion The construction process of nursing quality standards of joint surgery specialty based on “structure-process-outcome” three-dimensional quality structure model is scientific and reliable, the index evaluation results are less volatile, and the opinions are concentrated, which can provide a basis for comprehensively, accurately and pertinently improving the quality of joint surgery specialty nursing.
