Comparative study of suture anchor and Kirschner wire tension band internal fixation for the treatment of Fifth humeral base fracture

Abstract

Objective Comparison of suture anchor and Kirschner wire tension band internal fixation for the treatment of Fifth humeral base fracture. Methods Retrospective analysis of 33 patients with a fifth tibiofibular basal fracture in Lawrence-I were underwent treatment and complete follow-up from June 2013 to October 2018 according to the way of internal fixation, patients were divided into suture anchor group (15 cases) and Kirschner wire tension band group (18 cases). The intraoperative time, fracture reduction satisfaction, injury healing time and postoperative functional excellence rate were recorded and compared between two groups. Results There was no difference in the degree of fracture reduction, healing time, and postoperative complications between the suture anchor group and the Kirschner wire tension band group, The difference between the operation time of two groups was statistically significant (t=-8.714, P<0.05). The length of the surgical incision was statistically significant (t=-13.867, P<0.05). Comparison of intraoperative perspectives is statistically significant(t=-6.834, P<0.05). At the last follow-up, according to the forefoot function score of the American Foot and Ankle Association (AOFAS), the difference in functional recovery between the two groups was statistically significant (t=4.948, P<0.05). Conclusion Suture anchor is simple, minimally invasive, effective and no need to take internal fixation. Compared with Kirschner wire tension band, the operation time is reduced, the length of the surgical incision is shortened, and the number of fluoroscopy is reduced. It is an effective method for the treatment of the fifth metatarsal humeral fracture. Key words: Metatarsal Bones; fracture, Bone; Suture anchors; Bone Wires; Treatment Outcome
