Foot ankle Int ; We hope the reported case may be helpful to orthopedic surgeons facing similar cases and increasing awareness about this rare but serious entity. Often, these lesions occur in cases presenting a varus-cavus foot morphotype Under fluoroscopic control it lksfranc performed percutaneous osteosynthesis with Kirschner wires through both joints.

Articulation de Chopart

J Orthop Surg Hong Kong ; She was immobilized with a cast and cited at the ambulatory trauma service. The incidence of midfoot injuries is estimated at 3. Isolated dorsal midtarsal Chopart dislocation: Six weeks post-surgery, hardware and immobilization were removed.

Secondly, several key points for a proper diagnosis are given with the aim of reducing cases of misdiagnosis. Complejo Hospitalario de Navarra.

Artrologia Tobillo y pie

After careful debridement of fibrous interposed tissue in the Chopart space, congruence of lisfdanc and calcaneocuboidal joints was achieved. We recommend using orthotic insoles providing longitudinal arch support in order to prevent loss of reduction after starting to walk.

There was not swelling on the inspection, there were neither bruising nor skin changes. 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.


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

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. She was treated with a bandage and acetaminophen 1 gram every eight hours and was allowed ongoing support weight bearing using two crutches. It is composed of the condyloid talonavicular joint and the saddle-shaped calcaneocuboidal joint.

Delay in articulackon is common and may adversely affect the long-term prognosis 3. J Lisfarnc Ankle Surg ; Both joints together with the subtalar joint are involved fundamentally in the inversion and eversion movements 5,6. The talus-medial cuneiform-first metatarsal axis should be lined up on both a lateral and anteroposterior radiograph.

Furthermore, these injuries are frequently missed or misdiagnosed, often leading to a poor functional outcome 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.

Obtaining radiographs of the foot in three projections anteroposterior, lateral and oblique is essential. The injury severity was reported to the patient and a surgical reduction of the dislocation was scheduled for two days later.

Definitive diagnosis after cchopart 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. A study of outcome and morbidity.


Nineteen-year-old woman who came to our ambulatory trauma service with the diagnosis of a sprained right ankle for evolutionary control. Instr Course Lect ; 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.

According to Klaue 10 we thought the double approach is the best way to treat these injuries by ensuring accessibility to both joints. Then it proceeded to carefully repair capsulo-ligamentous structures.

Hermel Mb, Gershon-Cohen J. 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. The heterogeneity and complexity of midtarsal dislocations and fracture-dislocations hampers the existence of an international consensus classification.

Kirschner wires in appropriate cases are left equally implanted during this period. Injuries of the midtarsal joint.
