Objective To compare sinus tarsi approach(STA) and extensile L shape approach (ELA) in the surgical treatment of calcaneal fractures. Methods A total of 51 cases of calcaneal fractures treated from May 2014 to December 2016 were enrolled. Twenty of them were performed ORIF via the sinus tarsi approach, while the other 31 cases were performed ORIF via lateral extensile L shape approach. X-ray films were taken postoperatively to record the changes of B?hler angle and Gissane angle. The AOFAS, VAS and SF-36 scores were adopted to assess the therapeutic effect. Results The average follow-up period of STA group was 15.5 months. And patients in ELA group were followed up for an average period of 18.4 months. All the fractures in the series had a boney union at or before the final follow-up. The final correction of B?hler angle (34.60 ± 2.91)° , and Gissane angle (114.45 ± 2.91)° was significantly increased in the STA group; and the final correction of B?hler angle (33.55 ± 2.73)° , and Gissane angle (112.81 ± 4.15)° was also significantly increased in the ELA group; while there was no significant difference between the two groups. The final AOFAS scores , VAS scores and SF-36 scores of the STA were (83.56 ± 7.13), (1.78 ± 0.89), (88.95 ± 4.31) scores, while those in ELA group were (81.91 ± 9.89), (2.01 ± 1.33) and (86.65 ± 4.95) scores. There was no significant difference between the two groups (P>0.05). No wound problem happened in STA group, but there were 2 cases who had wound complications in ELA group. Conclusions No significant difference is found between the two groups in the short-term efficacy of the treatment for calaneal fracture. However, STA has the advantages of lower soft tissue complication rate.

Objective To study the effects of intermittent low?dose administration of recombinant human parathyroid hor?mone (1-34) [rhPTH(1-34)] in the expression of Osterix (Osx) during early stage of fracture healing. Methods Forty?eight 2?month old male Sprague?Dawley rats were underwent close unilateral femoral fracture and intramedullary nail fixation. The sub?jects were divided into 2 equal groups randomly:treatment group undergoing subcutaneous injection of rhPTH(1-34) 10 mg/kg/d immediately after the operation and control group undergoing subcutaneous injection of normal saline of the same dose. Six rats in each group were sacrifice at 2, 7, 14, and 21 days after operation. X?ray photography study was conducted at 7, 14 and 21 days. Tissue RNA and protein were extracted from the bone tissues of bilateral femurs and the expression levels of Osx mRNA and pro?tein were evaluated via real time quantitative PCR and Western?blotting. Results Fracture healing was significant at 14 days af?ter operation, and the progress of fracture healing was better in the rhPTH(1-34) group than in the control group at 14 and 21 days. The relative expression of Osx mRNA and protein in the fractured femurs of the rhPTH(1-34) group (5.02±0.5 and 10.03±0.8 for Osx mRNA, 3164.03±131 and 3509.02±126 for protein) at 14 and 21 days after the operation were significantly higher than those of the control group (2.30±0.4 and 4.01±0.7 for Osx mRNA, 1053.04±121 and 2721.03±123 for protein). However, there was no significant difference at 2 and 7 days after operation between the rhPTH(1-34) and control group. Conclusion Intermittent low?dose administration of rhPTH(1-34) up?regulates the expression levels of osteogenesis?specific Osx mRNA and protein in rats. It will accelerate the early phase of fracture healing process.
