Objective: To compare the clinical effects of two kinds of internal fixation methods in the treatment of Sanders II and type III calcaneal fractures.

Methods: 80 patients with Sanders from January 2015 -2016 year in January in our hospital were II-III type of calcaneal fractures, according to number table method, all patients were randomly divided into two groups by treating physicians, the steinmann pin group underwent steinmann pin poking closed reduction axial combined with lateral multiple hollow screws internal fixation, Open reduction group underwent conventional open reduction and internal fixation. Observe two groups of patients in hospital stays and costs; X-ray measurement of calcaneus Böhler angle, Gissane angle 2 months treatment before and after; Incidence of complications after 3 months of operation; two groups of patients with Maryland score after the operation of 1 years.

Results: the hospital stay and cost in steinmann pin group was significantly superior to that of the open reduction group (P<0.05); comparing the two groups of patients for 1 year Maryland scores, the pain, line, single item score and total score function in STEADITE needle group was no significant difference from the groups of patients with open reduction (P>0.05); the clinical curative effect of Steinmann pin patients was significantly higher than the open reduction group (P<0.05); the two groups of patients after treatment of Bohler angle and Gissane angle were significantly improved after treatment (P<0.05); the two groups of patients before treatment, Bohler 2 months after the treatment of angle, Gissane angle comparison, no statistically significant difference (P>0.05), compared two groups of postoperative complications, STEADITE needle group after treatment, complication rate (12.5%) was significantly lower than that of the open reduction group (30%), the difference was statistically significant (P<0.05).

Conclusion: In this study, we performed traditional open reduction and steinmann pin poking closed reduction axial combined with lateral multiple hollow screws internal fixation for the treatment of Sanders type II-III patients with calcaneal fractures, patients can obtain good clinical curative effect after operation, steinmann pin poking closed reduction axial combined with lateral multiple hollow screws internal fixation can be shortened the duration of hospitalization, reduce hospitalization costs and lower incidence of postoperative complications, it is suitable for clinicians to choose the application.
