Advanced balance and proprioceptive training for lower-extremity function is also important 6. Hermel Mb, Gershon-Cohen J.

Foot Anatomy and Biomechanics

Foot Ankle Int ; Subsequently, the patient should begin gradual partial and controlled weigh bearing using a custom molded foot orthotics and crutches. In the supine position, under general anesthesia, access to the midtarsal joint was performed through a two-way medial and lateral approach. 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. It is composed of the condyloid talonavicular joint and the saddle-shaped calcaneocuboidal joint.

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


Another important marker of midfoot articulacikn is the S-shaped Cyma line on lateral radiographs, sign of congruence of the talonavicular and calcaneocuboidal joints. J Orthop Surg Hong Kong ; The intervention ended with the limb immobilization with a short leg cast. Close reduction is a valid procedure in subluxations, acute dislocations when anatomy could articuulacion perfectly restored or in cases where surgery is contraindicated 5,9.

Fractures and dislocations of the midfoot: Injuries of the midtarsal joint. According to Klaue 10 we thought the double approach is the best way to treat these injuries by ensuring accessibility to both joints.

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. The incidence of midfoot injuries is estimated at 3. Chopart midtarsal joint dislocations are relatively rare but potentially serious injuries.

Under fluoroscopic control it was performed percutaneous osteosynthesis with Kirschner wires through both joints. The 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.

Chopart fractures and dislocations. On her second visit to ER also a not clear diagnosis was achieved. J Bone Joint Surg Br ; Past 12 months after articulafion loss of reduction was not observed.


Articulation de Chopart

Ip Ky, Lui Th. She was treated with a bandage and acetaminophen 1 gram every eight hours and was allowed ongoing support weight bearing using two crutches. All dislocations should be reduced emergently if possible, and all these eventually associated fractures must be reduced and correctly fixed. The importance of cuopart aware of midtarsal injuries.

Exercises that strengthen and stretch the gastrocnemius should be emphasized to the patient. At 48 hours after surgery the patient was articulaccion, after skin condition and postoperative radiographs were controlled. Three months postoperatively may be the time to begin normal shoe wearing 5. J Foot Ankle Surg ; A subtle radiographic sign of possible Chopart joint dislocation.

Articulaicon surgical correction of the length and shape of the longitudinal arch is important and technically challenging especially in combined Chopart-Lisfranc injuries 9.

Main Bj, Jowett Rl. La importancia de reconocer las lesiones mediotarsianas. The cuboid and distal calcaneus fractures, typically associated to midtarsal dislocations, produced by forced abduction or adduction lateral or medial stress are known as Nutcracker lidfranc.

She was immobilized with a cast and cited at the ambulatory trauma service.
