Assessment of the trauma degree and bone metabolism after minimally invasive subtalar arthrodesis treatment of traumatic subtalar arthritis caused by calcaneal fracture

摘要

Objective:To analyze the trauma degree and bone metabolism after minimally invasive subtalar arthrodesis treatment of traumatic subtalar arthritis caused by calcaneal fracture. Methods:A total of 76 patients with traumatic subtalar arthritis caused by calcaneal fracture were randomly divided into observation group and control group (n=38), control group received open talocalcaneal arthrodesis treatment, observation group received minimally invasive subtalar arthrodesis, and then the differences in postoperative trauma degree as well as the values of bone metabolism indexes and imaging parameter indexes was compared between two groups of patients.Results: 7 d after operation, serum SP, IL-6, PGE2,β-EP, MYO, IMA and MDA levels of observation group were significantly lower than those of control group while TAC level was significantly higher than that of control group; 1 month after operation, serum ALP, BGP and CT levels of observation group were significantly higher than those of control group while ACP and PTH levels were significantly lower than those of control group; 3 months after operation, talocalcaneal height under X-ray of observation group was higher than that of control group, and calcaneus-talus angle, talar tilt angle and calcaneal compensation angle were greater than those of control group.Conclusions:Minimally invasive subtalar arthrodesis helps to relieve the trauma degree and promote osteogenesis process in patients with traumatic subtalar arthritis, eventually improving patients' quality of life.
