“…Bone autograft and orthobiologics are commonly used for arthrodesis procedures about the foot and ankle to optimize union rates. 13,15,20 Buda et al 3 evaluated 189 TMT joints and found that the use of bone autograft significantly lowered the risk of nonunion (OR = 0.2). Not surprisingly, our results demonstrated that the use of bone graft was a positive predictor of union.…”

Background: Primary arthrodesis of Lisfranc fracture-dislocations is a reliable treatment option, yet concerns remain about nonunion. Nitinol staple use has recently proliferated in midfoot arthrodesis. The purpose of this study is to examine the union rate of primary arthrodesis of acute Lisfranc fracture-dislocations treated with nitinol staples compared with traditional plate-and-screw fixation. The secondary objective is to assess the difference in operative times and reoperation rates. Methods: Midfoot fracture-dislocations treated with primary arthrodesis by 7 foot and ankle orthopaedic surgeons were reviewed. Of 160 eligible patients, 121 patients (305 joints) met the required 4-month minimum radiographic follow-up. Radiographic outcomes were analyzed at the individual joint level. Each joint was classified as either staples alone (45 patients, 154 joints), staples plus plates and screws (hybrid) (45 patients, 40 joints), or plates and screws alone (31 patients, 111 joints). The primary outcome was arthrodesis union at each joint fused. Results: Nonunion was more common (9.0%, 10/111) among joints fixed with plate and screws than with hybrid (2.5%, 1/40) or staples only (1.3%, 2/154) ( P = .0085). Multivariable regression demonstrated that autograft use was independent associated with union ( P = .0035) and plate-and-screw only fixation was an independent risk factor for nonunion ( P = .0407). Median operating room and tourniquet times were shorter for hybrid (92 and 83 minutes) and staple only (67 and 63 minutes) constructs compared to plate-and-screw only fixation (105 and 95 minutes) ( P ≤ .0001 and .0003). There was no difference in reoperation rates among patients with different fixation types. Conclusion: We found that use of nitinol compression staple and bone autograft in primary arthrodesis of Lisfranc and midfoot fracture-dislocations was associated with both improved union rates and shorter tourniquet and operative times compared to traditional plate-and-screw fixation techniques. Level of Evidence: Level III, therapeutic.
