Mid-term Incidence of Tarsometatarsal Joint Arthrodesis Following Open Reduction With Internal Fixation (ORIF) of Lisfranc Injuries.

Open reduction with internal fixation (ORIF) of Lisfranc injuries are associated with an increased risk for secondary surgery including hardware removal and salvage arthrodesis. In the current literature, rates of salvage arthrodesis vary due to small sample sizes and a low incidence of Lisfranc injuries. There is little evidence to identify specific surgical and patient-related variables that may result in later arthrodesis. The purpose of this study is to determine the rate of tarsometatarsal joint arthrodesis following Lisfranc ORIF in a relatively large sample size. This retrospective review included patients who underwent ORIF for a Lisfranc injury between January 2007 and December 2012. A total of 146 patients met our criteria. Trans-articular fixation was used in 109 (74.6%) patients, 33 (22.6%) received percutaneous fixation and 4 (2.7%) extraarticular fixation. Five out of 120 (4.2%) patients required a salvage arthrodesis for post-traumatic arthritis that had a follow-up greater than 5 y but up to 10 y. The mean age of patients who underwent arthrodesis after ORIF was 24.5 ± 11.95 (16-48) y compared to 40.9 ± 15.8 (16-85) y. Patients who required an arthrodesis also had earlier hardware removal than patients who did not have an arthrodesis, 71.2 ± 28.3 (38-100) days and 131.4 ±101.2 (37-606) days, respectively. Patients who required salvage arthrodesis tended to be younger and hardware was removed earlier compared to those patients who did not require an arthrodesis. Four of the 5 patients who underwent a secondary arthrodesis had a loss of correction after hardware removal.
