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

Delay in diagnosis is common and may adversely affect the long-term prognosis 3. That same day was attended at the Emergency Room ER and after a physical exam and X rays is diagnosed with a sprained ankle. Three months postoperatively may be the time to begin normal shoe wearing 5. Greater series reported 3,7,9 agree on a set of conclusions in terms of outcomes but they all refer to acute lesions. Both approaches are safe and allow proper display of the key elements.

The nutcracker fracture of the cuboid by indirect violence. At 48 hours after surgery the patient was discharged, after skin condition and postoperative radiographs were controlled.

In chopadt, handling Chopart injuries is challenging and even more in the delay setting. 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. Isolated dorsal midtarsal Chopart dislocation: 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. There was not swelling on the inspection, there were neither bruising nor skin changes.

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 chopaart flexion lsifranc serves as radiological marker for serious ligamentous injury with midtarsal instability The midtarsal is a low mobile but essential joint for proper mechanics and architecture of the foot.


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

Foot Anatomy and Biomechanics

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 as occurred in our case.

She was immobilized with a cast and cited at the ambulatory trauma service. Am J Roentgenol ; J Foot Ankle Surg ; The surgical correction of the length and shape of the longitudinal arch is important and technically challenging especially in combined Chopart-Lisfranc injuries 9.

From that moment partial load bearing was allowed using an orthopedic hard-soled shoe with an orthotic medial arch support insole. She was treated with a bandage and lisfranx 1 gram every eight hours and was allowed ongoing support weight bearing using two crutches.

Nineteen-year-old woman who came to our ambulatory trauma service with the diagnosis of a sprained right ankle for evolutionary control. There are not great differences in prognostic terms comparing pure dislocations and fracture-dislocations. Finally deserves special attention the combined Chopart and Lisfranc dislocation, rare but especially serious.

Instr Course Lect ; The patient chopxrt no foot pain either at rest or walking, but referring some functional limitation when running. Open reduction and internal fixation is the most precisely method restoring the anatomy and thus gets the best functional outcomes. 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.

Arch Orthop Trauma Surg ; Finally, the related literature is reviewed. Inveterate dislocations are also an indication of open reduction.

We recommend using orthotic insoles providing longitudinal arch support in order to prevent loss of reduction after starting to walk. Clin Biomech lisfrnac These lesions tend to be underestimated but they are potentially serious Complex midfoot injuries could lead to severe functional impairment of mobility and quality of daily living. The cuboid and distal calcaneus fractures, typically associated to midtarsal dislocations, produced by forced abduction or adduction lateral or medial dhopart are known as Nutcracker fractures.


Complejo Hospitalario de Navarra. It requires careful dissection and protection of the peroneus superficialis and suralis nerves Fig. J Bone Joint Surg Br ; Introduction The midtarsal joint constitutes the anatomic limit between hindfoot and midfoot.

A study of outcome and morbidity.

Foot ankle Int ; Main Bj, Jowett Rl. The first aim is to present the case and its treatment. Exercises that strengthen and stretch the gastrocnemius should be emphasized to the patient. According to Klaue 10 we thought the double approach is the best way to treat these injuries by ensuring accessibility to both joints. 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.

Often, these lesions occur in cases presenting a pisfranc foot morphotype La importancia de reconocer las lesiones mediotarsianas. Subsequently, the patient should begin gradual partial and controlled weigh bearing using a custom molded foot orthotics and crutches.

Several series of cases of midtarsal fracture-dislocations are reported in the literature; however the data available on inveterate injuries is still scarce and its chopaart it is not well defined. Foot Ankle Clin ; Advanced balance and proprioceptive training for lower-extremity function is also important 6.
