Abstract:Objective To explore the efficacy of longitudinal incision without bone grafting and locking plate internal fixation in the treatment of Sanders type Ⅱ and Ⅲ calcaneal fractures with subtalar articular surface collapse. Methods 23 patients with Sanders typeⅡ and Ⅲ calcaneal fracture combined with subtalar joint surface collapse admitted to our hospital from April 2019 to December 2020 were selected. Among them,12 eligible patients were selected as the study subjects, and they were divided into a control group of 7 patients and an observation group of 5 patients based on different surgical methods.The observation group was treated with longitudinal incision without bone grafting and internal fixation with steel plates. The control group was treated with an expanded L-shaped incision on the lateral side of the calcaneus and bone grafting combined with locking steel plate internal fixation. Postoperative evaluation indicators such as time of operation, Bohler angle, Gissane angle, ankle-hindfoot score(AOFAS), and etc. were compared between the two group. Results There was no statistically significant difference in the operative time between the two groups (t=1.977, P>0.05). The postoperative Bohler angle and Gissane angle improved in both groups compared with those before treatment, and the differences within the groups were statistically significant (t=-4.281, -9.037, 5.413, 7.634, all P<0.05); and the improvement of Bohler angle in the observation group was better than that in the control group, and the differences between the groups were statistically significant (t=2.304, P<0.05), but the postoperative Bohler angle in both groups were within the normal range and was not considered clinically significant. The differences in the postoperative Gissane angle and AOFAS scores were not statistically significant when compared between the two groups (t=-0.712, 0.017, both P>0.05). Conclusion For Sanders typeⅡ and Ⅲ calcaneal fractures combined with subtalar joint collapse, the longitudinal incision without bone grafting and internal fixation with steel plates has similar surgical effects compared to the traditional lateral expansion L-shaped incision of the heel, and is one of the treatment methods for calcaneal fractures.
