All dislocations should be reduced emergently if possible, and all these eventually associated fractures must be reduced and correctly fixed.

The first aim is to present the case and its treatment. According losfranc Klaue 10 we thought the double approach is the best way to treat these injuries by ensuring accessibility to both joints. Joint stabilization with Kirschner wires 1,mm once the congruence is restored, may provide additional stability and could be performed after either open or close reduction.

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

Six weeks post-surgery, hardware and immobilization were removed. A study of outcome and morbidity. It exposes perfectly the calcaneocuboidal joint. 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 fractures.

Several series of cases of midtarsal fracture-dislocations are reported in the literature; however the data chopaet on inveterate injuries is still scarce and its management it is not well defined. Subsequently, the patient should begin gradual partial and controlled weigh bearing using a custom molded foot orthotics and crutches. The importance of being aware of midtarsal injuries.


Complex midfoot injuries could lead to severe functional impairment of mobility and quality of daily living. The main causes of midtarsal dislocation are motor vehicle accidents and falls from a height 3,9. Routine postoperative measures include rigid immobilization and no-weight bearing for a period of six to eight weeks. 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.

Secondly, several key points for a proper diagnosis are given with the aim of reducing cases of misdiagnosis. 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.

A subtle radiographic sign of possible Chopart joint dislocation. chpart

Delay in diagnosis is common and may adversely affect the long-term prognosis 3. They can be pure dislocations i. J Bone Joint Surg Br ; Clinical rating systems for the ankle-hindfoot, midfoot, chopary, and lesser toes.

Exercises that strengthen and stretch the gastrocnemius should be emphasized to the patient. Furthermore, these injuries are frequently missed or misdiagnosed, often leading to a poor functional outcome 3. Loss of joint congruence and stability in this region chpoart the whole function of the foot and a normal gait 7,8. Foot ankle Int ; Advanced balance and proprioceptive training for lower-extremity function is also important 6. In most of the cases are due to axial loads or torsional forces acting on the foot in plantar flexion.


In conclusion, handling Chopart injuries lisfranv challenging and even more in the delay setting.

Foot Anatomy and Biomechanics

Case report Nineteen-year-old woman who came to our ambulatory trauma service with the diagnosis of a sprained right ankle for evolutionary control. Injuries of the midtarsal joint. Another important marker of chopsrt injury is the S-shaped Cyma line on lateral radiographs, sign of congruence of the talonavicular and calcaneocuboidal joints.

Ankle and foot injuries: The injury severity was reported to the patient and a surgical reduction of the dislocation was scheduled for two days later. An open reduction was performed by a double approach chlpart and lateral and a Kirschner wire joint stabilization.

We recommend using orthotic insoles providing longitudinal arch support in order to prevent loss of reduction after starting to walk. Nineteen-year-old woman who came to our ambulatory dw service with the diagnosis of a sprained right ankle for evolutionary control. Discussion The midtarsal is a low mobile but essential joint for proper mechanics and architecture of the foot.

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