Complex midfoot injuries could lisfran to severe functional impairment of mobility and quality of daily living. Am J Roentgenol ; There are not great differences in prognostic terms comparing pure dislocations and fracture-dislocations. The midtarsal is a low mobile lisfrahc essential joint for proper mechanics and architecture of the foot. Subsequently, the patient should begin gradual partial and controlled weigh bearing using a custom molded foot orthotics and crutches.

Isolated dorsal midtarsal Chopart dislocation: She immediately felt local pain and swelling. The incidence of midfoot injuries is estimated at 3. Ankle and foot injuries: J Bone Joint Surg Br ; Tibiotalar joint mobility was preserved, and no painful. A subtle radiographic sign of possible Chopart joint dislocation.

An alternative to this method of treatment may be external artiiculacion, especially given the existence of serious soft tissue injury or when the lateral and medial columns are seriously fractured and shortened.

We hope the reported case may be helpful to orthopedic surgeons facing similar cases and increasing awareness about this rare but serious entity. At 48 hours after surgery the patient was discharged, after skin condition and postoperative radiographs were controlled.

Fractures and dislocations of the midfoot: Foot Ankle Int ; After careful debridement of fibrous interposed tissue in the Chopart space, congruence of talonavicular and calcaneocuboidal joints was achieved. It chopwrt composed of the condyloid talonavicular joint and the saddle-shaped calcaneocuboidal joint.


A midtarsal joint dislocation in a year-old-woman is described, in which diagnosis was performed at 8 weeks of evolution. Comparing the outcomes between Chopart, lisfranc and multiple metatarsal shaft fractures. Chopart midtarsal joint dislocations are relatively rare but potentially serious injuries.

There was not swelling on the inspection, there were neither bruising nor skin changes. Nineteen-year-old woman who came to our ambulatory trauma service with the diagnosis of a sprained right ankle for evolutionary control. 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.

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. Finally, the artiuclacion literature is reviewed.

It exposes perfectly the calcaneocuboidal joint.

Discussion The midtarsal is a low mobile but essential joint for proper mechanics and architecture of the foot. Often, these lesions occur in cases presenting a varus-cavus foot morphotype Under fluoroscopic control it was performed percutaneous osteosynthesis with Kirschner wires through both joints.

Another important marker of midfoot injury is the S-shaped Cyma line on lateral radiographs, sign of congruence of the talonavicular and calcaneocuboidal joints.

In the supine position, under general anesthesia, access to the midtarsal joint was performed through a two-way medial and lateral approach.

Foot Anatomy and Biomechanics

The patient had no foot pain either at rest or walking, but referring some functional limitation when running. The first aim is to present the case and its treatment. From that moment partial lisrranc bearing was allowed using an orthopedic hard-soled shoe with an orthotic medial arch support insole.

Given the poor evolution, with persistent pain and walking impairment, the patient returned to the ER at 6 weeks of the trauma suffered. Ip Ky, Lui Th. The intervention ended with the limb immobilization with a short leg cast. We recommend using orthotic insoles providing longitudinal arch support in order to prevent loss of reduction after starting to walk. The main causes of midtarsal dislocation are motor vehicle accidents and falls from a height 3,9.


Chopart dislocations with associated injuries, open reduction and fracture fixation represents the best option and allow reparation of damaged capsulo-ligamentous structures.

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. J Orthop Surg Hong Kong ; Secondly, several key points for a proper diagnosis are given with the aim of reducing cases of misdiagnosis.

The talus-medial cuneiform-first metatarsal axis should be lined up on both a lateral and anteroposterior radiograph. 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.

La importancia de reconocer las lesiones mediotarsianas. Then it proceeded to carefully repair capsulo-ligamentous structures.

Finally, the avulsion fracture of the dorsal talonavicular ligament caused by additional plantar flexion forced serves as radiological marker for serious ligamentous injury with midtarsal instability The midtarsal joint constitutes the anatomic limit between hindfoot and midfoot. The importance of being aware of midtarsal injuries. Delay in diagnosis is common and may adversely affect the long-term prognosis 3. These lesions tend to be underestimated but they are potentially serious Six weeks post-surgery, hardware and immobilization were removed.

In the delayed setting careful debridement of the Chopart space is essential. In cases of poor outcome and at the persistence of pain will be indicated salvage procedures including osteotomies and arthrodesis.
