Firstly the reevaluation of emergency radiographs was performed, finding a midtarsal joint plantar dislocation and an associated calcaneal fracture that had gone unnoticed Fig.

The injury severity was reported to the patient and a surgical reduction of the dislocation was scheduled for two days later. Lisfranc and Chopart injuries.

Past 12 months after surgery loss of reduction was not observed. Main Bj, Jowett Rl. Ip Ky, Lui Th. Am J Roentgenol ; Foot ankle Int ; Nineteen-year-old woman who came to our ambulatory trauma service with the diagnosis of a sprained right ankle for evolutionary control.

Articulación Transversa del Tarso. (Chopart) by Rebeca perez on Prezi

Complex midfoot injuries could lead to severe functional impairment of mobility and quality of daily living. Delay in diagnosis is common and may adversely affect the long-term prognosis 3. It is composed of the condyloid talonavicular joint and the saddle-shaped calcaneocuboidal joint. The midtarsal is a low mobile but essential joint for proper mechanics and architecture of the foot.


The heterogeneity and complexity of midtarsal dislocations and fracture-dislocations hampers the existence of an international consensus classification. 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. Main and Jowett 11 attempted to classify these injuries into five types according to the direction of the deforming force and the resulting displacement: Inveterate dislocations are also an indication of open reduction.

Exercises that strengthen and stretch the gastrocnemius should be emphasized to the patient.

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

Complejo Hospitalario de Navarra. Obtaining radiographs of the foot in three projections anteroposterior, lateral and oblique is essential. Instr Course Lect ; The ultimate goal is to restore alignment fe length in both columns of the foot, medial and lateral, getting proper congruence in the joints and ligamentous stability.

They can be pure dislocations i.


In conclusion, handling Chopart injuries is challenging and even more in the delay setting. The talus-medial cuneiform-first metatarsal axis should be lined up on both a lateral and anteroposterior radiograph. Kirschner wires in appropriate cases are left equally implanted during this period. Chopart midtarsal joint dislocations are relatively rare but potentially serious injuries.

Arch Orthop Trauma Surg atriculacion Clin Biomech ; J Orthop Surg Hong Kong ; Introduction The midtarsal joint constitutes the anatomic limit between hindfoot and midfoot. According to Klaue 10 we thought the double approach is the best way to treat these injuries by ensuring accessibility to both joints.

Injuries of the midtarsal joint.

She immediately felt local pain and swelling. Classification and epidemiology of mid-foot fractures. She was treated with a bandage and acetaminophen 1 gram every eight hours and was allowed ongoing support weight bearing using two crutches.

We hope the reported case may be helpful to orthopedic surgeons facing similar cases and increasing awareness about this rare lisfracn serious entity.
