Abstract

Abstract:

BACKGROUND: The headless reduction screw is an improved hollow screw. The clinical data are few compared with the common headless compression screws in the treatment of internal malleolus fracture.

OBJECTIVE: To compare the postoperative effects of headless reduction screws and common headless compression screws in the treatment of medial malleolus fractures.

METHODS: Totally 100 patients with medial malleolus fracture at the Department of Orthopedics, Affiliated Hospital to Chengdu University from July 2016 to October 2018 were retrospectively analyzed. Patients in the headless reduction screw group (n=50) were treated with headless reduction screw for internal fixation. Patients in the common headless compression screw group (n=50) were treated with common headless compression screws. Ankle radiographic examination was performed in each group after surgery to assess fracture healing time, complications, and AOFAS score.

RESULTS AND CONCLUSION: (1) There was no significant difference in fracture healing time and AOFAS score between the two groups 6 weeks to 18 months after surgery (P > 0.05). (2) Analysis of complications: delayed healing appeared in one case 7 months after operation, and internal fixation fracture in one case 12 months after operation in the headless reduction screw group. Wound infection appeared in one patient 2 days after operation, vein thrombosis in one patient 3 months after operation, delayed healing in two patients 6 and 9 months after operation, overpressure in one patient 1 day after operation, and internal irritation in one patient 5 months after operation in the common headless compression screw group. There was no statistical difference in the number of complications between the two groups (P > 0.05). The number of complications was less in the headless reduction screw group than in the common headless compression screw group. (3) These results conclude that the clinical effect of applying headless reduction screw is similar to that of common headless compression screw group in the treatment of medial malleolus fracture. Headless reduction screws can reduce the complications properly.
