Main Bj, Jowett Rl. From that moment partial load bearing was allowed using an orthopedic hard-soled shoe with an orthotic medial arch support insole. In conclusion, handling Chopart injuries is challenging and even more in the delay setting.

Avulsion fracture of the dorsal talonavicular ligament: Introduction The midtarsal joint constitutes the anatomic limit between hindfoot and midfoot.

Greater series reported 3,7,9 agree on a set of conclusions in terms of outcomes but they all refer to acute lesions.

Given the poor evolution, with persistent pain and walking impairment, the patient returned to the ER at 6 weeks of the trauma suffered.

The nutcracker fracture of the cuboid by indirect violence. Since then, the midtarsal joint is referred chopaet Chopart joint. Foot Ankle Int ; Firstly the reevaluation of emergency radiographs was performed, finding a midtarsal joint plantar dislocation and an associated calcaneal fracture that had gone unnoticed Fig.

La importancia de reconocer las lesiones mediotarsianas. Past 12 months after surgery loss of reduction was not observed. Inveterate dislocations are also an indication of open reduction.


Joint stabilization with Kirschner wires 1,mm once the congruence is restored, may provide additional stability and could be performed after either open or close reduction. Discussion The midtarsal is a low mobile but essential joint for proper mechanics and architecture of the foot.

In most of the cases are due to axial loads or torsional forces acting on the foot in plantar flexion. Hermel Mb, Gershon-Cohen J. She was immobilized with a cast and cited at the ambulatory trauma service.

Definitive diagnosis after evaluation of CT images was midtarsal dislocation of the right foot with associated fracture of the anterolateral calcaneus process Nutcracker fracture and osteochondral fracture of the talar head of approximately 8 weeks of evolution.

Ankle and foot articulackon All dislocations should be reduced emergently if possible, and all these eventually associated fractures must be reduced and correctly fixed.

Three months postoperatively may be the time to begin normal shoe wearing 5.

Articulation de Chopart

It is composed of the condyloid talonavicular joint and the saddle-shaped calcaneocuboidal joint. Nineteen-year-old woman who came artifulacion our ambulatory trauma service with the diagnosis of a sprained right ankle for evolutionary control. Fractures and dislocations of the midfoot: Isolated dorsal midtarsal Chopart dislocation: In the present study a midtarsal joint dislocation of eight weeks of evolution is reported which it was reduced through a double medial and lateral approach.

Besides describing the treatment of this particular injury, this study is aimed lisfdanc increasing the level of clinical suspicion in order to avoid misdiagnosis such as occurred in our case. Complex midfoot lidfranc could lead to severe functional impairment of mobility and quality of daily living. It exposes perfectly the calcaneocuboidal joint. We recommend using orthotic insoles providing longitudinal arch support in order to prevent loss of reduction after starting to walk.

Case report Nineteen-year-old woman who came to our ambulatory trauma service with the diagnosis of a sprained right ankle for evolutionary control. Their rarity should not be a reason to underestimate them, as they are really complex and potentially serious lesions. J Foot Ankle Surg ; According to Klaue 10 we thought the double approach is the best way to treat these injuries by ensuring accessibility to both joints.

The frequency is by far the highest for the medial and plantar dislocations. Advanced balance and proprioceptive training for lower-extremity function is also important 6.

Secondly, several key points for a proper diagnosis are given with the aim of reducing cases of misdiagnosis. Clin Biomech ; The injury severity was reported to the patient and a surgical reduction of the dislocation was scheduled for two days later. Subsequently, the patient should begin gradual partial and controlled weigh bearing using a custom molded foot orthotics and crutches.
