Abstract:
Objective:To compare the efficacy of minimally invasive steel plate combined with percutaneous hollow nail fixation through the sinus tarsi incision versus "L"-shaped incision steel plate fixation in the treatment of calcaneal fractures.Methods:A retrospective analysis was conducted on 103 cases of Sanders type II-IV calcaneal fractures treated with minimally invasive steel plate combined with percutaneous hollow nail fixation through sinus tarsi incision from January 2017 to March 2024 at the orthopedic department of Hangzhou Sir Run Run Shaw Hospital (minimally invasive group). An additional 103 cases treated with "L"-shaped incision steel plate fixation during the same period were included as controls (open group). The preoperative hospital stay, surgical time, postoperative hidden blood loss, postoperative hospital stay, postoperative infection rate, postoperative Bohler angle, Gissane angle, calcaneal mid-width, sustentacular effective fixation rate, and American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score at 6 and 12 months postoperatively were compared between the two groups.Results:There were no statistically significant differences in age, gender, diabetes, smoking history, and body mass index between the minimally invasive group and the open group ( P>0.05). In the minimally invasive group, the preoperative hospital stay (3.1±1.5 days), postoperative hospital stay (3.5±1.5 days), hidden blood loss (293.3±71.4 ml), surgical time (64.4±13.2 min), and AOFAS score at 6 months postoperatively (79.9±3.9) were superior to those in the open group (7.1±0.7 days, 5.6±0.9 days, 408.3±101.7 ml, 91.5±24.3 min, and 70.5±6.1, respectively) ( P<0.05), with no significant difference in AOFAS score at 1 year postoperatively ( P>0.05). Additionally, the preoperative hospital stay (3.7±1.5 days), postoperative hospital stay (4.0±2.0 days), hidden blood loss (336.3±75.3 ml), and AOFAS score at 6 months postoperatively (77.4±3.8) in the minimally invasive group were superior to those in the open group (7.6±0.9 days, 8.2±2.6 days, 441.3±89.2 ml, and 64.6±8.4, respectively) ( P<0.05), with no significant difference in surgical time and AOFAS score at 1 year postoperatively ( P>0.05). Within-group comparisons indicated that as fracture severity increased, preoperative ( P<0.05) and postoperative hospital stays ( P<0.05) increased in the open group, while surgical time increased in the minimally invasive group ( P<0.05). AOFAS scores at 6 months postoperatively varied between complex and simple fractures in both groups ( P<0.05). There were no statistically significant differences in postoperative Bohler angle, Gissane angle, and calcaneal mid-width between the two groups ( P>0.05). The sustentacular effective fixation rate in the minimally invasive group was 85.4%, superior to 47.4% in the open group for simple fractures ( P<0.05), with no statistically significant difference for complex fractures ( P>0.05). The incision infection rate was 0 in the minimally invasive group compared to 3 cases (3%) in the open group, with no statistically significant difference ( P=0.246). Conclusion:Minimally invasive steel plate combined with percutaneous hollow nail fixation through sinus tarsi incision for calcaneal fractures offers the advantages of shorter hospital stay, reduced surgical trauma, lower incision infection rate, and better short-term efficacy compared to open incision. It is suitable for most Sanders type II-IV calcaneal fractures.
