Abstract:
BACKGROUND: Olecranon fracture-dislocations are complicated fractures and dislocations of the elbow, which adds certain challenges to clinical diagnosis and treatment. Although the continuous improvement of medical standards has made some progress in the clinical diagnosis and treatment of olecranon fracture-dislocations, some controversial issues need to further discuss. OBJECTIVE: To consult and sort out the relevant literature about the clinical diagnosis and treatment of olecranon fracture-dislocations, and give a summary. METHODS: The first author searched the relevant documents collected by Web of Science, PubMed and CNKI databases from 2000 to 2020. The key words were “olecranon; elbow; fracture dislocation; 3D printing” in English and Chinese. The massive relevant literature was reviewed and collected. The literature was classified and analyzed from the aspects of anatomical mechanics, injury characteristics, diagnostic typing and surgical treatment. RESULTS AND CONCLUSION: (1) The anatomy of the olecranon, coronoid process, radial head, and the anatomical mechanical characteristics between the soft tissues affect the clinical diagnosis and treatment of olecranon fracture-dislocations. (2) Both anterior and posterior dislocations have their own injury characteristics and are easily confused with Monteggia fractures. Accurate grasp of physical examination and auxiliary imaging examination is conducive to clinical diagnosis. (3) The posterior midline approach is more commonly used, and other approaches should be combined if necessary. Proper fixation and repair of bone and soft tissue, as well as timely auxiliary external fixator, are conducive to improving the clinical efficacy of olecranon fracture-dislocations. (4) However, the damage mechanism of the rear olecranon fracture-dislocations needs to be further explored, and whether to establish independent classification of olecranon fracture-dislocations needs further discussion. The effectiveness of the indirect fixation of the coronoid process behind the olecranon still needs further research. (5) In addition, the emerging three-dimensional printing technology is of great significance for preoperative planning and simulation of bone trauma, and will be more conducive to the development of clinical diagnosis and treatment of olecranon fracture-dislocations.
