The midtarsal joint constitutes the anatomic limit between hindfoot and midfoot.

Articulation de Chopart

Under fluoroscopic control it was performed percutaneous osteosynthesis with Liwfranc wires through both joints. Advanced balance and proprioceptive training for lower-extremity function is also important 6. The frequency is by far the highest for the medial and plantar dislocations. Chopart fractures and dislocations. According to Klaue 10 we thought the double approach is the best way to treat these injuries by ensuring accessibility to both joints.

Ip Ljsfranc, Lui Th. Three months postoperatively may be the time to begin normal shoe wearing 5. At 48 hours after surgery the patient was discharged, after skin condition and postoperative radiographs were controlled.

J Foot Ankle Surg ; In most of the cases are due to axial loads or torsional forces acting on the foot lizfranc plantar flexion. The importance of being aware of midtarsal injuries.

Clin Biomech ; We hope the reported case may be helpful to orthopedic surgeons facing similar cases and increasing awareness about this rare but serious entity.

Firstly the reevaluation of articulaclon radiographs was performed, finding a midtarsal joint plantar dislocation and an associated calcaneal fracture that had gone unnoticed Fig. Often, these lesions occur in cases presenting a varus-cavus foot morphotype Am J Roentgenol ; Agticulacion same day was attended at the Emergency Room ER and after a physical exam and X rays is diagnosed with a sprained ankle.

The injury severity was reported to the patient and a surgical reduction of the dislocation was scheduled for two days later.

Palpation was painful over the navicular bone and it drew attention to the flattening of the inner arch of xhopart foot compared to the contralateral side. 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.

Isolated dorsal midtarsal Chopart dislocation: Then it proceeded to carefully repair capsulo-ligamentous structures. La importancia de reconocer las lesiones mediotarsianas. An open reduction was performed by a double approach medial and lateral and a Kirschner wire joint stabilization.

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.

She immediately felt local pain and swelling. 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 aticulacion.

The intervention ended with the limb immobilization with a short leg cast. 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.

The talus-medial cuneiform-first metatarsal axis should be lined up on both a lateral and choparg radiograph. Tibiotalar joint mobility was preserved, and no painful.

Discussion The midtarsal is a low mobile but essential joint for proper mechanics and architecture of the foot. Since then, the midtarsal joint is referred as Chopart joint.

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. In conclusion, handling Chopart injuries is challenging and even more in the delay setting.

They can be pure dislocations i. Inveterate dislocations are also an indication of open reduction.

The incidence of midfoot injuries is estimated at 3. 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. In cases of poor outcome and at the persistence of pain will be indicated salvage procedures including osteotomies and arthrodesis.

The combined Chopart-Lisfranc lesion seems to present significantly worse results. The present study has several objectives.

These lesions tend to be underestimated but they are potentially serious The reasons for misdiagnosis could be their low prevalence and the absence of artixulacion radiological signs in lisfrranc to a third of cases 5, Another important marker of midfoot injury is the S-shaped Cyma line on lateral radiographs, sign of congruence of the talonavicular and calcaneocuboidal joints.

The first aim is to present the case and its treatment. Greater series reported 3,7,9 agree on a set of conclusions in terms of outcomes but they all refer to acute lesions. It requires careful dissection and protection of the peroneus superficialis and suralis nerves Fig.
