Objective: To explore the effect of the fixation of the bone plate, the hollow screw and the band anchorage in the large segmental fracture of the humerus.

Methods: A total of 108 patients with displaced large fissure of the humerus were selected as the study subjects from January 2015 to January 2017, and they were randomly divided into fixation group (group A), hollow screw fixation group (group B) and bandline anchor fixation group (group C), 36 cases in each group. The intraoperative blood loss, operation time, length of stay and fracture healing time were recorded for the three groups of patients. The shoulder function of the three groups was scored. The complications were recorded in three groups of patients follow up for 2 years.

Results: The intraoperative blood loss and operation time of groups B and C were significantly lower than those of group A (P<0.05). The operation time of group C was significantly lower than that of group B (P<0.05). The time of fracture healing in groups B and C was significantly lower than that in group A (P<0.05). The time of fracture healing in group C was significantly lower than that in group B (P<0.05). The scores of group C were significantly higher than those of groups B and C, and there was significant difference between the two groups (P<0.05). A group of 6 cases of complications, B group of 2 cases, C group of 2 cases.

Conclusion: Compared with the fixation of the plate and the fixation of the hollow screw, the clinical effect of the line anchorage fixation is better, the patient is well recovered and worthy of clinical promotion.
