Application value of wire anchor in repairing triangular ligament rupture in ankle fracture treated with internal fixation

ObjectiveTo explore the clinical advantages of open reduction and internal fixation combined with wire anchor in the treatment of ankle fracture complicated with deltoid ligament rupture.

MethodsThe clinical data of 72 patients with ankle fracture complicated with deltoid ligament rupture treated with open reduction and internal fixation were retrospectively analyzed.Thirty-six deltoid ligament rupture cases repaired with wire anchor and 36 deltoid ligament rupture cases without repair were divided into the observation group and control group, respectively.Two groups were followed up for 6 to 16 months, and the therapeutic effects of the related indicators were compared between two groups.

ResultsThe operations in all cases were successful, and the fracture reduction in two groups was good.The difference of the medial distance of ankle points between two groups was statistically significant(P < 0.05).Six cases with medial instability of ankle joint in control group after operation were found, and the movement of plantar flexion in 3 cases of control group was obviously limited.No medial instability of ankle joint and screw out in observation group were found.The motion range of ankle metatarsal flexion and dorsiflexion in observation group were better than those in control group(P < 0.01).The AOFAS ankle-hind foot function score in observation group was significantly higher than that in control group(P < 0.01).The total excellent and good rate in observation group and control group were 86.1% and 75.0%, respectively, and the difference of which was not statistically significant(P>0.05).

ConclusionsOpen reduction and internal fixation combined with wire anchor in repairing ankle fracture complicated with deltoid ligament rupture can improve the ankle stability, and help to restore the ankle mobility.
