Treatment of Lisfranc injuries with open reduction internal fixation or ORIF was associated with lower costs and fewer complications than primary arthrodesis, but there were higher hardware removal rates with ORIF, according to results presented at the American Orthopaedic Foot & Ankle Society Annual Meeting.
“Open reduction internal fixation is definitely an option that you can use, and it is a beneficial option you can use overall,” Bryan Vopat, MD, assistant professor at University of Kansas Hospital, told Orthopedics Today. “It is not saying that fusion is necessarily bad, but for a while there was a run of a lot of people who were saying that fusion is the answer and I think that the study’s overall message is that open reduction internal fixation still has a role when fixing Lisfranc injuries and is something someone should consider.”
ORIF vs arthrodesis
Vopat, Brandon Barnds, MD, and colleagues used Pearl Diver datamining software to identify patients with Lisfranc fractures who were treated nonoperatively or who underwent primary ORIF or primary arthrodesis. Researchers performed a cost analysis, which was based on insurance companies’ reimbursement rates
Barnds, who presented the findings, said at the meeting, “We then split these up into subgroups based on patients having at least one complication after the initial surgical management, patients having subsequent hardware removal and if the revision or fusion came right after.”
Of 2,200 patients identified with Lisfranc injuries, 30% underwent ORIF and 10% underwent arthrodesis. Cost, complication rate and hardware removal was significantly different between the ORIF and arthrodesis group. Primary arthrodesis was more expensive by about $1,000, Barnds said.
“There was apparent complication rate in the arthrodesis group [of] about 7% and [in the] hardware removal category, the primary ORIF had a higher rate by about 25%,” he said.
Patients in the ORIF group had a low progression to a secondary fusion of about 2.5% which occurred at an average of 308 days. Barnds noted.
Comparison studies needed
The study has limitations in that it is a database study and researchers were unable to review patient outcomes, Vopat, whose teaching affiliation is with the University of Kansas Medical Center, said.
“Also, it is only a 7-year follow-up in the database, so some of the open reduction internal fixations may have went on to fusions and we would not catch those patients,” Vopat said. “It is difficult to tell how the patients did because there were no outcomes for this, so it does not tell how their pain scores were, what activities they were able to return back to.”
He noted future research should include a review of prospective outcomes and costs in either a comparative or randomized controlled study. – by Casey Tingle
