Minimally invasive fixation with a locking plate for Sanders Ⅱ and Ⅲ calcaneal fractures via the tarsal sinus approach / 中华创伤骨科杂志

Objective:To evaluate the minimally invasive fixation with a locking plate via the tarsal sinus approach in the surgical treatment of Sanders Ⅱ and Ⅲ calcaneal fractures.Methods:A retrospective study was conducted to analyze the 65 patients who had been surgically treated for Sanders Ⅱ and Ⅲ calcaneal fractures at Department of Foot and Ankle Surgery, Binzhou Medical College Hospital from April, 2019 to September, 2020. There are 44 males and 21 females with an age of (42.5±10.4) years, and 46 Sanders type Ⅱ fractures and 19 Sanders type Ⅲ ones. The patients were divided into group L and group S according to surgical methods. Group S of 35 cases was fixated with a minimally invasive locking plate through the tarsal sinus incision while group L of 30 cases fixated with a locking plate through the L-shaped incision. The 2 groups were compared in terms of waiting time before surgery, surgical time, hospital stay, intraoperative bleeding, visual analogue scale (VAS) at 3 days after surgery, American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score at 1 year after surgery, excellent and good rate by the Maryland foot function score, B?hler angle, Gissane angle, varus angle, and complications.Results:There was no significant difference in the general data before surgery between the 2 groups, showing comparability ( P>0.05). All patients were followed up for (13.3±1.6) months after surgery. The waiting time before surgery [(2.8±1.8) d], surgical time [(80.7±9.9) min], hospital stay [(6.7±1.9) d], intraoperative bleeding [(54.3±14.2) mL], and VAS at 3 days after surgery [6 (5, 7) points] in group S were all significantly less or lower than those in group L [(8.2±2.8) d, (105.0±15.7) min, (14.6±3.4) d, (74.3±12.8) mL, and 7 (6, 8) points] (all P<0.05). At one year after surgery, the AOFAS ankle-hindfoot score [(90.1±3.5) points] in group S was significantly higher than that in group L [(83.5±6.7) points] ( P<0.05), but there was no statistically significant difference in the excellent and good rate by the Maryland foot function score between the 2 groups [91.4% (32/35) versus 86.7% (26/30)] ( P=0.695). The B?hler angle, Gissane angle, and varus angle were significantly improved in all patients one year after surgery compared with the values before surgery ( P<0.05), but there were no statistically significant differences within either group or between the 2 groups at 3 days or 1 year after surgery ( P>0.05). Peroneal muscle pain was reported in 1 case in group S; there were 2 cases of skin necrosis, 1 case of incision hematoma and 1 case of sural nerve injury in group L. Conclusion:The minimally invasive fixation with a locking plate via the tarsal sinus approach is an effective treatment for Sanders Ⅱ and Ⅲ calcaneal fractures.

Efficacy of Sinus Tarsal Approach Compared With Conventional L-Shaped Lateral Approach in the Treatment of Calcaneal Fractures: A Meta-Analysis.

Background: This study aims to compare the efficacy of the sinus tarsal approach (STA) with that of the conventional L-shaped lateral approach (CLSLA) in the treatment of calcaneal fractures by meta-analysis. Methods: PubMed, Embase, Web of Science, the Chinese National Knowledge Infrastructure, and China Wanfang database were searched to collect clinical randomized or non-randomized controlled trials of STA and CLSLA in the treatment of calcaneal fractures from January 2010 to May 2020. The data were analyzed by Stata 15.0 software. Results: A total of 12 clinical trials were included, all of which were retrospective studies, including 961 patients. The results showed that when STA was compared with CLSLA, there was no difference in operation time with mean difference (MD) = -5.51 [95% confidence interval (CI): -12.57 to 1.55, P > 0.05], less bleeding during operation with MD = -18.49 (95% CI:-23.79 to -13.18), no difference in Böhler angle after an operation with MD = 0.78 (95% CI: -0.09 to 1.65) and in Gissane angle with MD = -0.07 (95% CI: -1.90 to 1.77), no difference in American Orthopedic Foot and Ankle Society score with MD = 2.16 (95% CI: -1.07 to 5.38), higher-excellent and better rate of Maryland food function with relative ratio = 1.12 (95% CI: 1.04 to 1.20), and lower of incidence of postoperative complications with relative ratio = 0.23 (95% CI: 0.14-0.37). Conclusion: STA was more effective than CLSLA in the treatment of calcaneal fractures. Moreover, STA had advantages in less intraoperative bleeding, higher-excellent and better rate of Maryland foot function, lower incidence of postoperative complications, and higher safety.

Research progress concerning the sinus tarsal approach for treatment of calcaneal fractures / 中华创伤骨科杂志

Treatment of calcaneal fractures has always been the focus of many clinical researchers.The goals of traditional surgical treatment are not only to restore the integrity of calcaneal articular surface but also to reconstruct the anatomy of the calcaneus.More importantly,we need to reduce postoperative soft tissue swelling and incidence of postoperative complications.In recent years,scholars have reported satisfactory clinical efficacy and prognosis resulting from a sinus tarsal approach for treatment of calcaneal fractures.This paper reviews the latest research progress concerning the sinus tarsal approach for treatment of calcaneal fractures at home and abroad,intending to provide helpful information for the clinical surgeons.
