Surgical Treatment of Lisfranc Injury With Plantar Plate Approach.

Midfoot injuries are the second most common athletic foot injury documented in the published data. High-energy Lisfranc dislocations are commonly seen secondary to traumatic etiologies and disrupt the strong midfoot ligaments supporting the arch. These injuries require immediate surgical intervention to prevent serious complications such as compartment syndrome and amputation. The present case series reports a new Lapidus plate system used in 3 patients who underwent arthrodesis procedures for Lisfranc joint dislocation. Three patients in their fourth to fifth decade of life presented with a traumatic injury at the Lisfranc joint and subsequently underwent open reduction and internal fixation using the plantar Lapidus Plate System (LPS; Arthrex, Naples, FL). The LPS was placed in a predetermined safe zone, with measures taken to avoid the insertional points of the tibialis anterior and peroneus longus tendons. Radiographs were obtained for ≤6 months postoperatively and revealed consolidation across the fusion site, intact hardware, and satisfactory alignment. On examination, the corrections were well maintained and free of signs of infection. Clinical evaluation showed no indication of motion within the tarsometatarsal joint and no tenderness to palpation surrounding the fusion sites. All 3 patients successfully returned to their activities of daily living without discomfort or pain. Modern surgical treatment of Lisfranc injuries most commonly includes open reduction and internal fixation, accompanied by arthrodesis. The present case series has demonstrated that the LPS provides relief, stability, and compression of the joint in our small cohort of patients who experienced a traumatic injury to the Lisfranc joint.
