Fractures and dislocations of the midfoot: Then it proceeded to carefully repair capsulo-ligamentous structures. 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 xe seriously fractured and shortened.

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.

Comparing the outcomes between Chopart, lisfranc and multiple metatarsal shaft fractures. We hope the reported case may be helpful to orthopedic surgeons facing similar cases and increasing awareness about this rare but serious entity.

There are not great differences in prognostic terms comparing pure dislocations and fracture-dislocations.

Foot Anatomy and Biomechanics

The midtarsal joint constitutes the anatomic limit between hindfoot artiulacion midfoot. Obtaining radiographs of the foot in three projections anteroposterior, lateral and oblique is essential. They can be pure dislocations i. 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. Ip Ky, Lui Th.

Complex midfoot injuries could lead to severe functional impairment of mobility and quality of daily living. Secondly, cgopart key points for a proper diagnosis are given with the aim of reducing cases of misdiagnosis.

Given the poor evolution, with persistent pain and walking impairment, the patient returned to the ER at 6 weeks of the trauma suffered.

The first aim is to present the case and its treatment. Artkculacion fracture of cholart dorsal fhopart ligament: Inveterate dislocations are also an indication of open reduction. Am J Roentgenol ; 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.

Hermel Mb, Gershon-Cohen J. The surgical correction of the length and shape of the longitudinal arch is important and technically challenging especially in combined Chopart-Lisfranc injuries 9. 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. Advanced balance and proprioceptive training for lower-extremity function is also important 6.

Routine postoperative measures include rigid immobilization and no-weight bearing for a period of six to eight weeks. Finally, the related literature is reviewed. Complejo Hospitalario de Navarra.

Main and Jowett 11 attempted to classify these injuries into five types according to the direction of the deforming force and the resulting displacement: Arch Orthop Trauma Surg ; The reasons for misdiagnosis could be their low prevalence and the absence of obvious radiological signs in up to a third of cases 5, The heterogeneity and complexity of midtarsal dislocations and fracture-dislocations hampers the existence of an international consensus classification.

Chopart fractures and dislocations. Greater series reported 3,7,9 agree on a set of conclusions in terms of outcomes but they all refer to acute lesions. 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. The midtarsal is a low mobile but essential joint for proper mechanics and architecture of the foot. 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.

Since then, the midtarsal joint is referred as Chopart joint. Foot ankle Int ; Another important marker of midfoot injury is the S-shaped Cyma line on lateral radiographs, sign of congruence of the talonavicular and calcaneocuboidal joints.

Chopart midtarsal joint dislocations are relatively rare but potentially serious injuries. It is composed of the condyloid talonavicular joint and the saddle-shaped calcaneocuboidal joint. A study of outcome and morbidity. After careful debridement of fibrous interposed tissue in the Chopart space, congruence of talonavicular and calcaneocuboidal joints was achieved.

It exposes perfectly the calcaneocuboidal joint. Main Bj, Jowett Rl. Both joints together lusfranc the subtalar joint are involved fundamentally in the inversion and eversion movements 5,6.

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 Articulacioon 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.
