Abstract:

OBJECTIVE: To investigate the biomechanical characteristics of shoulder joint bone injury, to classify and summarize the treatment approach and mechanism underlying artificial biomate4rial intervention after shoulder joint bone injury.
METHODS: A computer-based online search of PubMed database (http://www.ncbi.nlm.nih.gov/PubMed) and CNKI database (www.cnki.net / index.htm) was performed using key words of “shoulder joint, fracture, biological materials, treatment” to search the title and abstracts. Studies related to the biomechanical characteristics of should joint, shoulder joint injury and treatment of artificial biomaterials were included, and those recently published or published in the authority journals were preferred in the same field.
RESULTS: A total of 24 studies were involved in analysis. Shoulder joint is the most flexible joint with the largest movement range, Shoulder joint bone injury is common in gymnastics due to sudden force or violence in the process of upper extremity supporting. Present repair technology for serious shoulder injury is mostly shoulder prosthesis, with the advanced modern medicine, artificial biological engineering has been gradually applied to the field of sports medicine, artificial biomaterials are becoming mature and diversified in bone injury treatment, but rarely reported in the shoulder joint fracture repair.
CONCLUSION: In the shoulder joint prosthesis design process, the goal is to restore the physiological structure and function of shoulder joint before injury. Therefore, the basic parameters that prosthesis design requires should be obtained by means of continuous in-depth study of anatomy, while the development of prosthesis can also promote morphology research and progress, plays a promoting role in development and in-depth study of bone morphology and surface modification. In addition, researchers have achieved good results in bone repair material selection, processing and surface modification. With the cell biology and molecular biology methods and technology advance, as well as the use of gene therapy, researches on shoulder joint bone injury repair will enter a new phase, and offer a new research direction for the proper use of artificial materials for should joint fracture repair.
