[Research progress of interphalangeal arthrodesis].

OBJECTIVE: To review the research progress of interphalangeal arthrodesis in the treatment of interphalangeal joint deformity.
METHODS: The literature about interphalangeal arthrodesis at home and abroad was extensively consulted, and the indications, fusion methods, fixation methods, complications, and so on were summarized and analysed.
RESULTS: The indications of interphalangeal arthrodesis are hammer toe, claw toe, and mallet toe. From the different forms of fusion surface, fusion methods include end-to-end, peg-in-hole, conical reamer type, and V-shape arthrodesis. There are three kinds of fixation methods: Kirschner wire fixation, stainless-steel wire suture fixation, and intramedullary fixation, and there are many kinds of intramedullary fixation. The complications of interphalangeal arthrodesis include vascular injury, fixation related complications, and postoperative complications.
CONCLUSION: Interphalangeal arthrodesis is a good way to correct some deformities of toes, but the incidence of various complications can not be ignored, and there is still a lack of clinical research on interphalangeal arthrodesis.
