ObjectiveTo review the causes of Latarjet surgery failure and various revision surgeries, in order to provide the reference for the revision of treatment options for Latarjet surgery failure.MethodsLiterature on the causes of Latarjet surgery failure and revision surgeries was extensively reviewed and analyzed. ResultsLatarjet surgery is widely used in clinical practice for recurrent anterior dislocation of shoulder with glenoid defects, especially for the defects of more than 25%. The main reasons for its failure are ununion, bone resorption, graft dislocation, trauma, and graft fracture, etc. The revision surgeries are diverse, the standard treatment has not yet been formed. The revision surgeries include open iliac bone grafting, microscopic Eden-Hybinette surgery, soft tissue reconstruction, open or arthroscopic bone grafting, etc. The differences among the revisions are mainly reflected in grafts, complications, and their costs.ConclusionLatarjet surgery is difficult to operate and requires high technical requirements for the surgeons. It is necessary to continuously improve the surgical technology to reduce the complications related to Latarjet surgery and its revision surgery.
Objective To summarize surgical procedures of hip-preservation based on peri-collapse stage of osteonecrosis of the femoral head (ONFH). Methods The basic points of peri-collapse stage theory was expounded. The related literature on surgical procedures was summarized and analyzed based on the theory. Results Surgical procedures of hip-preservation tend to emphasize on mechanical repair, giving consideration to biological repair. It is consistent with the essence of peri-collapse stage theory, which attaches great importance to biomechanical stability. Conclusion Peri-collapse stage theory has a guiding significance to the choice of surgical timing and approach, and it is one of the important theoretical basis for hip-preservation treatment.
