Abstract

Objective: This study aimed to compare the clinical efficacy and prognosis of internal fixation with hollow screw and fixation with absorbable cartilage nail in the treatment of tibia intercondylar eminence fracture.

Patients and methods: A total of 116 patients with tibia intercondylar eminence fracture treated in our hospital from June 2014 to September 2016 were collected. Among them, 54 patients in the control group were fixed with hollow screws and 62 patients in the observation group were fixed with absorbable cartilage nails. Lvsholm score and tegner activity rating were compared after 6 months of treatment, so was time of operation, healing time of fracture, and adverse reactions of patients in the two groups after treatment; besides, logistics regression analysis was used to analyze the risk factors of poor prognosis of patients, and ROC curve was used to analyze the predictive value of independent risk factors in poor prognosis.

Results: There was no significant difference in Lvsholm score and tegner activity rating between the two groups. The healing time of fracture and time of operation of patients in the observation group were significantly higher than those in the control group, there was no difference in the occurrence of adverse reactions, and higher course of disease (OR: 1.370, 95%CI: 1.224-2.482), Meyers-McKeever classification type IV (OR: 1.474, 95%CI: 1.137-1.376), and old fracture (OR: 1.468, 95%CI: 1.362-1.835) were independent risk factors for poor prognosis of patients and had certain predictive value.

Conclusions: Internal fixation with hollow screw and fixation with absorbable cartilage nail have good efficacy and prognosis, and there is no significant difference. However, fixation with hollow screw has a short recovery time, and higher course of disease, old fracture and Meyers-McKeever type IV are independent risk factors for poor prognosis of patients with tibia intercondylar eminence fracture.
