Articulation de Chopart
Routine postoperative measures include rigid immobilization and no-weight bearing for a period of six to eight weeks. Also, good outcomes can be achieved performing initially a midtarsal arthrodesis, and this could represent the best solution in case of massive articular surface destruction. Inveterate dislocations are also an indication of open reduction. Case report Nineteen-year-old woman who came to our ambulatory trauma service with the diagnosis of a sprained right ankle for evolutionary control.
Then it proceeded to carefully repair capsulo-ligamentous structures. Under fluoroscopic control it was performed percutaneous osteosynthesis with Kirschner wires through both joints. The talus-medial cuneiform-first metatarsal axis should be lined up on both a lateral and anteroposterior radiograph.
Wrticulacion 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. In most of the cases are due articulaciom axial loads or torsional forces acting on the foot in plantar flexion. Often, these lesions occur in cases presenting a varus-cavus foot morphotype In the delayed setting careful debridement of the Chopart space is essential. Isolated dorsal midtarsal Chopart dislocation: Past 12 months after surgery loss of reduction was not observed.
The combined Chopart-Lisfranc lesion seems to present significantly worse results. Firstly the reevaluation of emergency radiographs was performed, finding a midtarsal joint plantar dislocation and an associated calcaneal fracture that had gone unnoticed Fig.
We lisffanc 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 Ip Ky, Lui Th. On her second visit to ER also a not clear diagnosis was achieved. The importance of being aware of midtarsal injuries. Several series of cases of midtarsal fracture-dislocations are reported in the literature; however the data available on inveterate injuries is still scarce and its management it is not well defined.
Advanced balance and proprioceptive training for lower-extremity function is also important 6. J Bone Joint Surg Br ; The patient had no foot pain either at rest or walking, but referring some functional limitation when running. Avulsion articullacion of the dorsal talonavicular ligament: The midtarsal is a low mobile but essential joint for proper mechanics and architecture of the foot.
There are not great differences in prognostic terms comparing pure dislocations and fracture-dislocations. Kirschner wires in appropriate oisfranc are left equally implanted during this period.
Furthermore, these injuries are frequently missed or misdiagnosed, often leading to a poor functional outcome 3. Greater series reported 3,7,9 agree on a set of conclusions in terms of outcomes but they all refer to acute lesions.
CT offers additional information when associated lesions or to plan future treatments and is not hesitating to apply if diagnosis is unclear. Given the poor evolution, with persistent pain and walking impairment, the patient returned to the ER at 6 weeks of the trauma suffered.

Clinical rating systems for the ankle-hindfoot, midfoot, hallux, and lesser toes. A midtarsal joint dislocation in a year-old-woman is described, in which diagnosis was performed at 8 weeks of evolution.
An alternative to this method of treatment may be external fixation, especially given the existence of serious soft tissue injury or when the lateral and medial columns are seriously fractured and shortened.
J Foot Ankle Surg ; Three months postoperatively may be the time to begin normal shoe wearing 5. Computed tomography CT was requested. Articulaacion incidence of midfoot injuries is estimated at 3.
Close reduction is a valid procedure in subluxations, acute dislocations when anatomy could be perfectly restored or in cases where surgery is contraindicated 5,9. Chopart midtarsal joint dislocations are relatively rare but potentially serious injuries. The intervention ended with the limb immobilization with a short leg cast.
Foot Ankle Int ; Their low prevalence and the possible absence of evident radiological findings cannot justify misdiagnosis because an adequate and correct treatment is required to achieve a proper clinical outcome.

Comparing the outcomes between Chopart, lisfranc and multiple metatarsal shaft fractures. Secondly, several key points for a proper diagnosis are given with the aim of reducing cases cjopart misdiagnosis. 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. At one-year of follow-up, loss of reduction was not observed and the patient was pain-free, although she referred to functional limitation when running.
A subtle radiographic sign articulacjon possible Chopart joint dislocation. J Orthop Surg Hong Kong ; Main Bj, Jowett Rl. An open reduction was performed by a double approach medial and lateral and a Kirschner wire joint stabilization.
