Lisfranc fracture radiology

There is lateral displacement of the lesser metatarsals with respect to the first metatarsal with widening of the space between the 1st and 2nd metatarsal base, lisfranc fracture radiology, with an intra-articular fracture from the medial margin of the base of the 2nd metatarsal. Homolateral Lisfranc fracture dislocation.

At the time the article was last revised Ramon Olushola Wahab had no financial relationships to ineligible companies to disclose. Lisfranc injuries , also called Lisfranc fracture-dislocations , are the most common type of dislocation involving the foot and correspond to the dislocation of the articulation of the tarsus with the metatarsal bases. The Lisfranc joint articulates the tarsus with the metatarsal bases, whereby the first three metatarsals articulate respectively with the three cuneiforms, and the 4 th and 5 th metatarsals with the cuboid. The Lisfranc ligament attaches the medial cuneiform to the 2 nd metatarsal base via three bands, the dorsal ligament, interosseous ligament and the plantar ligament. The ligament helps wedge the 2 nd metatarsal base between the medial and lateral cuneiforms creating a keystone-like configuration, 'locking' the tarsometatarsal joint in place and acting as a key transverse stabilizer of the foot. Its integrity is crucial to the stability of the Lisfranc joint. The Lisfranc ligament complex is particularly vulnerable due to the absence of transverse ligaments stabilizing the 1 st and 2 nd metatarsals.

Lisfranc Fracture Dislocation. Capsule Retention Following Capsule Endoscopy. Chalk Stick Fracture in Ankylosing Spondylitis. Updated: Nov 15, Trauma due to falling off a roof. Figure 1. Figure 2. Type B2 Lisfranc injury. B Arrow demonstrates the increase in distance between the first and second metatarsals. The red lines show the misalignment or lateral displacement of the 2nd metatarsal bone over the second cuneiform bone and the preserved alignment of the first metatarsal with the first cuneiform bone. The first cuneiform bone is also fractured and there is lateral shift of the 2nd, 3rd, 4th, and 5th metatarsals. C Lateral radiograph demonstrates dorsal sub dislocation of the metatarsal base red circle. A Lisfranc Fracture is a relatively rare injury, with an incidence of 1 per 55, persons per year and 0. The trapezoidal shape between these bones, the transverse arch, provides stability. Injury can encompass minor ligamentous lesions and fracture dislocations with more severe trauma, as in this case [2].

Clinical History: A 17 year-old male presents with the history of pain due to a football injury incurred three days prior. What are the findings? What is your diagnosis? Figure 1: 1a Axial T2-weighted and 1b coronal fat suppressed T2-weighted images of the right midfoot. Figure 2: The axial image demonstrates mid substance disruption of the interosseous component of the Lisfranc ligament complex arrow. Figure 3: The coronal image demonstrates mid substance disruption of the dorsal arrowhead and interosseous arrow components of the Lisfranc ligament complex. In the general population, injuries to the Lisfranc ligament complex are uncommon, occurring in approximately 1 in 50, people.

To systematically review current diagnostic imaging options for assessment of the Lisfranc joint. PubMed and ScienceDirect were systematically searched. Thirty articles were subdivided by imaging modality: conventional radiography 17 articles , ultrasonography six articles , computed tomography CT four articles , and magnetic resonance imaging MRI 11 articles. Some articles discussed multiple modalities. The following data were extracted: imaging modality, measurement methods, participant number, sensitivity, specificity, and measurement technique accuracy.
