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 importance of being aware of midtarsal injuries. The frequency is by far the highest for the medial and plantar dislocations. Clin Biomech ; A midtarsal joint dislocation in a year-old-woman is described, in which diagnosis was performed at 8 weeks of evolution.

Complejo Hospitalario de Navarra. Definitive diagnosis after evaluation of CT articculacion 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. 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 xrticulacion occurred in our case.

It is composed of the condyloid talonavicular joint and the saddle-shaped calcaneocuboidal joint. Instr Course Lect ; J Orthop Surg Hong Kong ; It requires careful dissection and protection of the peroneus superficialis and suralis nerves Fig. Ip Ky, Lui Th. The nutcracker fracture of the cuboid by indirect violence.

Foot Anatomy and Biomechanics

Ankle and foot injuries: An open reduction was performed by a double approach medial and lateral and a Kirschner wire joint stabilization. Secondly, several key points for a proper diagnosis are given with the aim of reducing cases of misdiagnosis. The main causes of midtarsal dislocation are motor vehicle accidents and falls from a height 3,9.


J Foot Ankle Surg ; The first aim is to present the case and its treatment.

CT offers additional information when associated lesions or to plan future treatments and is not hesitating to apply if diagnosis is unclear. Then it proceeded to carefully repair capsulo-ligamentous structures. A study of outcome and morbidity. Joint stabilization with Kirschner wires 1,mm once the congruence is restored, may provide additional stability and could be performed after either open choaprt close reduction.

After careful debridement of fibrous interposed tissue in the Chopart space, congruence of talonavicular and calcaneocuboidal joints was achieved. Obtaining radiographs of the foot in three projections anteroposterior, lateral and oblique is essential. According to Klaue 10 we thought the double approach is the best way to treat these injuries by fhopart accessibility to both joints.

Computed tomography CT was requested. Kirschner wires in appropriate cases are left equally implanted during this period. In cases of poor outcome and at the persistence of pain will be indicated salvage procedures including osteotomies and arthrodesis. Injuries of the midtarsal joint. Both joints together with the subtalar joint are involved fundamentally in the inversion and eversion movements 5,6.

Under fluoroscopic control it was performed percutaneous osteosynthesis with Kirschner wires through both joints. Foot Ankle Clin ; Articylacion J Roentgenol ; Advanced balance and proprioceptive training for lower-extremity function is also important 6.

On her second visit to ER also a not clear diagnosis was achieved.

Articulation de Chopart

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

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


Open reduction and internal fixation is the articylacion precisely method restoring the anatomy and thus gets the best functional outcomes. We recommend using orthotic insoles providing longitudinal arch support in order to prevent loss of reduction after starting to walk.

Three months postoperatively may be the time to begin normal shoe wearing 5. At one-year of follow-up, loss of reduction was not observed and chipart patient was pain-free, although she referred to functional limitation when running. Classification and epidemiology of mid-foot fractures.

Complex midfoot injuries could lead to severe functional impairment of mobility and quality of daily living. Chopart midtarsal joint dislocations are relatively rare but potentially serious injuries. Both approaches are afticulacion and allow lsfranc display of the key elements.

Several series of cases of midtarsal fracture-dislocations are reported lisgranc the literature; however the data available on inveterate injuries is still scarce and its management it is not well defined. Main and Jowett 11 attempted to classify these injuries into five types according to the direction of the deforming force and the resulting displacement: Firstly the reevaluation of emergency radiographs was performed, finding a midtarsal joint plantar dislocation and an associated calcaneal fracture cbopart had gone unnoticed Fig.

Six weeks post-surgery, hardware and immobilization were removed.

Since then, the midtarsal joint is referred as Chopart joint.
