Abstract: Objective To compare the clinical efficacy of the trans-fibular approach locking plating versus fibular strut combined with hollow screw for tibial pitch and calcaneal arthrodesis. Methods A retrospective study was performed on the 87 patients who had undergone tibial pitch and calcaneal arthrodesis from June 2016 to June 2019 in our department. 41 were treated by fibular strut combined with hollow screw (fibular flap group) and 46 by locking plating (locking plate group). The operation time, drainage volume, fusion rate, American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hind foot Scale, visual analogue scale(VAS) and complications were compared between the two groups. Results All patients received successful operation. There was no statistical difference in the operation time between the two groups (P>0.05). Postoperative drainage volume of fibular flap group was (253.6±34.7) mL and locking plate group (212.8±20.1) mL, there were statistical differences in the postoperative drainage volume between the two groups (P<0.05). The fusion rate at 10 weeks after operation of the locking plating group was (73.9 %) significantly lower than that of the fibular strut combined with hollow screw group (95.1 %) (P<0.05). There was no statistical difference in the fusion rate at 6 months after operation, AOFAS score, VAS score at 12 months after operation (P>0.05). All incisions were healed in the first stage and the fibula osteotomy site irritation appeared in 3 patients in the locking plate group. Conclusions Both open lateral ankle locking plating and fibular strut combined with hollow screw are effective procedure to tibial pitch and calcaneal arthrodesis. The fibular strut combined with hollow screw preserves part of the blood supply of the fibula and can achieve faster fusion. In addition, the irritation symptoms of the fibula osteotomy site is not obvious, and the shape of the ankle joint after fusionalso has advantages.
