A subtle radiographic sign of possible Chopart joint dislocation. CT offers additional information when associated lesions or to plan future treatments and is not hesitating to apply if lisffranc is unclear. The patient reported, as the only history of interest, trauma eight weeks ago, in which she struck a heavy cabinet directly over xrticulacion foot in plantar flexion.
Both joints together with the subtalar joint are involved fundamentally in the inversion and eversion movements 5,6.

Hermel Mb, Gershon-Cohen J. Complex midfoot injuries could lead to severe functional impairment of mobility and quality of daily living. In the delayed setting careful cnopart of the Chopart space is essential.
Advanced balance and proprioceptive training for lower-extremity function is also important 6. In the present study a midtarsal joint dislocation of eight weeks of evolution is reported which it was reduced choart a double medial and lateral approach. An open reduction was performed by a double approach medial and lateral and a Kirschner wire joint stabilization. There was not swelling on the inspection, there were neither bruising nor skin changes.
Both approaches are safe and allow proper display of the key elements. J Foot Ankle Surg ; Tibiotalar joint mobility was preserved, and no painful. Finally, the related literature is reviewed.
The cuboid and distal calcaneus fractures, typically associated to midtarsal dislocations, produced by forced abduction or adduction lateral or medial stress are known as Nutcracker fractures. Often, these lesions occur in cases presenting a varus-cavus foot morphotype Also, good outcomes can be achieved performing initially a midtarsal adticulacion, and this could represent the best solution in case of massive articular surface destruction.
Articulation de Chopart
Clin Biomech ; Three months postoperatively may be the time to begin normal shoe wearing 5. Main Bj, Jowett Rl. It exposes perfectly the calcaneocuboidal joint. Open reduction and internal fixation is the most precisely method restoring the anatomy and thus gets the best functional outcomes. Subsequently, the patient should begin gradual partial and controlled weigh bearing using a custom molded foot orthotics and crutches.
The surgical correction of the length and shape of the longitudinal arch is important and technically challenging especially in combined Chopart-Lisfranc injuries 9.
Computed tomography CT was requested. Past 12 months after surgery loss of reduction was not observed. Fractures and dislocations of the midfoot: It is composed of the condyloid talonavicular joint and the saddle-shaped calcaneocuboidal joint.

Discussion The midtarsal is a low mobile but essential joint for proper mechanics and architecture of the foot. The heterogeneity and complexity of midtarsal dislocations and fracture-dislocations hampers the existence of an international consensus classification. Finally deserves special attention the combined Chopart and Lisfranc dislocation, rare but especially serious. Obtaining radiographs of dhopart foot in three projections anteroposterior, lateral and oblique is essential.
Nineteen-year-old woman who came to our ambulatory trauma service with the diagnosis of a sprained right ankle for evolutionary control.
Comparing the outcomes between Chopart, lisfranc and multiple metatarsal shaft fractures. She immediately felt local pain and swelling. All dislocations should be reduced emergently if possible, and all these eventually associated fractures must be reduced and correctly fixed.
