Clinical study on the surgical treatment of atypical Lisfranc joint complex injury

Figure 1 A 30-year-old male with a right foot injury due to a heavy crush. A and B: X-ray images of the injured foot in the orthophoria and oblique positions, showing the avulsion fracture line of the metatarsal base and the displacement of the fracture; dislocation is not obvious; C: The postoperative incision; D-F: Preoperative computed tomography scans, showing multiple avulsion fracture fragments of the metatarsal base; G and H: X-ray images after operation in the orthophoria and oblique positions.

Figure 2 A 47-year-old female with sprains. A and B: X-ray images of the injured foot in the orthophoria and oblique positions, showing the avulsion fracture line of the metatarsal base and the displacement of the fracture; dislocation is not obvious; C: Lateral X-ray image under weight-bearing circumstances before surgery, showing no obvious displacement; D-G: Preoperative computed tomography scans showing multiple avulsion fracture fragments of the metatarsal base; H and I: X-ray images after operation in the orthophoria and oblique positions.

Figure 3 A 37-year-old female injured in a car accident. A and B: X-ray images of the injured foot in the orthophoria and oblique positions, showing the avulsion fracture line of the metatarsal base; displacement of the fracture and dislocation is not obvious; C-E: Preoperative computed tomography scans showing multiple avulsion fracture fragments of the metatarsal base; F: Signs of ecchymosis on the sole; G and H: X-ray images after operation in the orthophoria and oblique positions.

Figure 4 A 54-year-old female injured in a car accident. A and B: X-ray images of the injured foot in the orthophoria and oblique positions showing the avulsion fracture line of the metatarsal base and the displacement of the fracture and dislocation is not obvious; C: Signs of ecchymosis on the sole; D and E: Preoperative computed tomography scans, showing multiple avulsion fracture fragments of the metatarsal base; F and G: X-ray images after operation in the orthophoria and oblique positions; H: Incision and exploration during the operation showing tears in the dorsal joint capsule and ligament; the joint is unstable.
