Foot Anatomy and Biomechanics

There was not swelling on the inspection, there were neither bruising nor skin changes. In the present study a midtarsal joint dislocation of eight llisfranc of evolution is reported which it was reduced through a double medial and lateral approach. 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. Foot ankle Int ; Main and Jowett 11 attempted to classify these injuries listranc five types according to the direction of the deforming force and the resulting displacement: Three months postoperatively may be the time to begin normal shoe wearing 5. That same day was attended at the Emergency Room ER and after a physical raticulacion and X rays is diagnosed with a sprained ankle.

Nineteen-year-old woman who came to our ambulatory trauma service with the diagnosis of a sprained right ankle for evolutionary control. In the delayed setting careful debridement of the Chopart space is essential. Ankle and foot injuries: The heterogeneity and complexity of midtarsal dislocations and fracture-dislocations hampers the existence of an international consensus classification.


Finally deserves special attention the combined Chopart and Lisfranc dislocation, rare but chppart serious. Instr Course Lect ; A midtarsal joint dislocation in a year-old-woman is described, in which diagnosis was performed at 8 weeks of evolution. According to Klaue articulwcion we thought agticulacion double approach is the best way to treat these injuries by ensuring accessibility to both joints.

Foot Ankle Int ; 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.

Hermel Mb, Gershon-Cohen J. Their rarity should not be a reason to underestimate them, as they are really complex and potentially serious lesions.

She was treated with a bandage and acetaminophen 1 gram every eight hours and was allowed ongoing support weight bearing using two crutches. Both approaches are safe and allow proper display of the key elements.

The midtarsal joint constitutes the anatomic limit between hindfoot and midfoot. Arch Orthop Trauma Surg ; Isolated dorsal midtarsal Chopart dislocation: Delay in diagnosis is common and may adversely affect the long-term prognosis 3. Firstly the reevaluation of emergency radiographs was performed, finding a midtarsal joint plantar dislocation and an associated calcaneal fracture that had gone unnoticed Fig.

Am J Roentgenol ; Finally, the avulsion fracture of the dorsal talonavicular ligament caused by additional plantar flexion forced serves as radiological marker for articulacioh ligamentous injury with articuladion instability Furthermore, these injuries are frequently missed or misdiagnosed, often leading to a poor functional outcome 3. Clin Biomech ; Chopart midtarsal joint dislocations are relatively rare but potentially serious injuries. In cases of poor outcome and at the persistence of pain will be indicated salvage procedures including osteotomies and arthrodesis.


Complejo Hospitalario de Navarra.

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.

An open reduction was performed by a double approach medial and lateral and a Kirschner wire joint stabilization. The cuboid and distal calcaneus fractures, typically associated to midtarsal dislocations, produced by forced abduction or adduction articjlacion or medial stress are known as Nutcracker fractures.

Past 12 months after surgery loss of reduction was not observed. They can be pure dislocations i. The patient reported, as the only history of interest, trauma eight weeks ago, in which she struck a heavy cabinet directly over the foot in plantar flexion.

The ultimate goal is to restore alignment and length in copart columns of the foot, medial and lateral, getting proper congruence in the joints and ligamentous stability. 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.

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. The present study has several objectives. J Orthop Surg Hong Kong ; The frequency is by far the highest for the medial and plantar dislocations.

It exposes perfectly the calcaneocuboidal joint. After careful debridement of fibrous interposed tissue in the Chopart space, congruence of talonavicular and calcaneocuboidal joints was achieved.
