Main and Jowett 11 attempted to classify these injuries into five types according to re direction of the deforming force and the resulting displacement: According to Klaue 10 we thought the double approach is the best way to treat these injuries by ensuring accessibility to both joints.

Furthermore, these injuries are frequently missed or misdiagnosed, often leading to a poor functional outcome 3.

Chopart fracture | Radiology Reference Article |

At 48 hours after surgery the patient was discharged, after skin condition and postoperative radiographs were controlled. The incidence of midfoot injuries is estimated at 3. Clinical rating systems articuoacion the ankle-hindfoot, midfoot, hallux, and lesser toes. Complex midfoot injuries could lead to severe functional impairment of mobility and quality of daily living.

Clin Biomech ; 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. Obtaining radiographs of the foot in three projections anteroposterior, lateral and oblique is essential.

The frequency is by far the highest for the medial and plantar dislocations. The midtarsal is a low mobile but essential joint for proper mechanics and architecture of the foot. Close reduction is articukacion valid procedure in subluxations, acute dislocations when anatomy could be perfectly restored or in cases where surgery is contraindicated 5,9.


Secondly, several key points for a proper diagnosis are given with the aim of reducing cases of misdiagnosis. It is composed of the condyloid talonavicular joint and the saddle-shaped calcaneocuboidal joint.

In most of lksfranc cases are due to axial loads or torsional forces acting on the foot in plantar flexion. Advanced balance and proprioceptive training for lower-extremity function is also important 6. Then it proceeded to carefully repair capsulo-ligamentous structures. A study of outcome and morbidity.

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.

These lesions tend to be underestimated but they are potentially serious The importance of being aware of midtarsal injuries. The combined Chopart-Lisfranc lesion seems to present significantly worse results. Since then, the midtarsal joint is referred as Chopart joint. 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.

We recommend using orthotic insoles providing longitudinal arch support in order to prevent loss of reduction after starting artidulacion walk. 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.

Articulation de Chopart

A midtarsal joint dislocation in a year-old-woman is described, in which diagnosis was performed at 8 weeks articjlacion evolution. Greater series reported 3,7,9 agree on a set of conclusions in terms of outcomes but they all refer to acute lesions.

The ultimate goal is to restore alignment and length in both columns of the chopar, medial and lateral, getting proper congruence in the joints and ligamentous stability. Fractures and dislocations of the midfoot: Past 12 months after surgery loss of reduction was not observed. Arch Orthop Chopat Surg ; La importancia de reconocer las cchopart mediotarsianas. Discussion The midtarsal is a low mobile but essential joint for proper mechanics and architecture of the foot.


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. Hermel Mb, Gershon-Cohen J.

Foot ankle Int ; Complejo Hospitalario de Navarra. Besides describing the treatment of this particular injury, this study is aimed at increasing the level of clinical suspicion in order to avoid misdiagnosis such as occurred in our case. 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 nutcracker fracture of the cuboid by indirect violence. Loss of joint congruence and stability in this region jeopardizes the whole function of the foot and a normal gait 7,8.

J Orthop Surg Chpoart Kong ; Six weeks post-surgery, hardware and immobilization pisfranc removed. There are not great differences in prognostic terms comparing pure dislocations and fracture-dislocations.

The reasons for misdiagnosis could be their low prevalence and the absence of obvious radiological signs in up to a third of cases 5, J Bone Joint Surg Br ; Ip Ky, Lui Th.

Foot Anatomy and Biomechanics

Finally, the related literature is reviewed. That same day was attended at the Emergency Room ER and after a physical exam and X rays is diagnosed with a sprained ankle. An open reduction was performed by a double approach medial and lateral and a Kirschner wire joint stabilization.
