859 A Single Center Retrospective Study Comparing Retrograde TibioTaloCalcaneal Nailing vs Open Reduction Internal Fixation of Ankle Fractures in a Comorbid Elderly Population

Abstract Aim The aim of this paper is to compare the functional outcomes and complication rates ankle fractures treated with retrograde tibiotalocalcaneal nail (TTC) open reduction internal fixation (ORIF). Method Matched cohorts according age Charlson Comorbidities Index (CCI) (mean=6) were established by performing a retrospective search prospectively collated Bluespier® database for patients within our unit who underwent TTC nailing (ORIF) acute trauma from 2015 2021. Results 32 (8 males/ 24 females) identified in both ORIF groups mean ages 78.4 (55–96) 78.3 (52–93) respectively. Mean follow-up length was 6 months groups. All classified AO classification. 3.1% 44A, 71.9% 44B, 25% 44C group compared 59.4% 44B 37.5% group. Surgical site infection rate 9.4% 6.3% Both had similar implant failure 9.4%. 2/32 (6.3%) suffered periprosthetic 1 them required re-operation. 45% returned their pre-injury level mobility 40.6% at last follow up. Conclusions Our study showed that can be useful treatment option comorbid elderly, restoring function enabling return full weight bearing immediately after surgery.
