Foot Anatomy and Biomechanics

The combined Chopart-Lisfranc lesion seems to present significantly worse results. The patient reported, as the only history of interest, trauma eight weeks ago, in which she struck a heavy cabinet directly over the foot in plantar flexion.

The ultimate goal is to restore alignment and length in both columns of the foot, medial and lateral, getting proper congruence in the joints and ligamentous stability. The present study has several objectives.

Am J Roentgenol ; The main causes of midtarsal dislocation are motor vehicle accidents and falls from a height 3,9.

Ip Ky, Lui Th. A subtle radiographic sign of possible Chopart joint dislocation.

Articulation de Chopart

Chopart fractures and dislocations. After careful debridement of fibrous interposed tissue in the Chopart space, congruence of talonavicular and calcaneocuboidal joints was achieved. Isolated dorsal midtarsal Chopart dislocation: Often, these lesions occur in cases presenting a varus-cavus foot morphotype Both approaches are safe and allow proper display of the key elements.


The nutcracker fracture of the cuboid by indirect violence. Chopart dislocations with associated injuries, open reduction and fracture fixation represents the best option and allow reparation of damaged capsulo-ligamentous structures.

Palpation was painful over the navicular bone and it drew attention to the flattening of the inner arch of the foot compared to the contralateral side. The surgical correction of the length and shape of the longitudinal arch is important and technically challenging especially in combined Chopart-Lisfranc injuries 9. A midtarsal joint dislocation in a year-old-woman is described, in which diagnosis was performed at 8 weeks of evolution.

Then it proceeded to carefully repair capsulo-ligamentous structures. Nineteen-year-old woman who came to our ambulatory trauma service with the diagnosis of a sprained right ankle for evolutionary control.

We recommend using orthotic insoles providing longitudinal arch support in order to prevent loss of reduction after starting to walk. These lesions tend to be underestimated but they are potentially serious Obtaining radiographs of the foot in three projections anteroposterior, lateral and oblique is essential. Main Bj, Jowett Rl.

A study of outcome and morbidity. Their rarity should not be a reason to underestimate them, as they are really complex and potentially serious lesions. Subsequently, the dr should begin gradual partial and controlled weigh bearing using a custom molded foot orthotics and crutches. Under fluoroscopic control it was performed percutaneous osteosynthesis with Kirschner wires through both joints.

Complex midfoot injuries could lead to severe functional impairment of mobility and quality of daily living. Since then, the midtarsal joint is referred as Chopart joint. The importance of choprat aware of midtarsal injuries.

Six weeks post-surgery, hardware and immobilization were removed. All dislocations should be reduced emergently if possible, and all these eventually associated fractures must be reduced and correctly fixed. The incidence of midfoot injuries is estimated at 3.

Comparing the outcomes between Chopart, lisfranc and multiple metatarsal shaft fractures.
