Definitive diagnosis after evaluation of CT images was midtarsal dislocation of the right foot with associated fracture of the anterolateral calcaneus process Nutcracker fracture and osteochondral fracture of the talar head of approximately 8 weeks of evolution.
Three months postoperatively cchopart be the time to begin normal shoe wearing 5. A midtarsal joint dislocation in a year-old-woman is described, in which diagnosis was performed at 8 weeks of evolution.
Discussion The midtarsal is a low mobile but essential joint for proper mechanics and architecture of the foot. The intervention ended with the limb immobilization with a short leg cast. Fractures and dislocations of the midfoot: The talus-medial cuneiform-first metatarsal axis should be lined up on both a lateral and anteroposterior radiograph.
After careful debridement of fibrous interposed tissue in the Chopart space, congruence of talonavicular and calcaneocuboidal joints was achieved.
On her second visit to ER also a not clear diagnosis was cuopart.
Foot Anatomy and Biomechanics
It choart perfectly artciulacion calcaneocuboidal joint. CT offers additional information when associated lesions or to plan future treatments and is not hesitating to apply if diagnosis is unclear. Isolated dorsal midtarsal Chopart dislocation: 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 surgical correction of the length and shape of the longitudinal arch is important and technically challenging especially in combined Chopart-Lisfranc injuries 9.
Foot Ankle Clin ; La importancia de reconocer las lesiones lisftanc. Classification and epidemiology of mid-foot fractures. Subsequently, the patient should begin gradual partial and controlled weigh bearing using a custom molded foot orthotics and crutches. In the present study a midtarsal joint dislocation of eight weeks of evolution is reported which it was reduced through a double medial and lateral approach.
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. Foot Ankle Int ; The combined Chopart-Lisfranc lesion seems to present significantly worse results.
Often, these lesions occur in cases presenting a varus-cavus foot morphotype 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. There are not great differences in prognostic terms comparing pure dislocations and fracture-dislocations.
Chopart fractures and dislocations. Delay in diagnosis is common and may adversely affect the long-term prognosis 3. Loss of joint congruence and stability in this region jeopardizes the whole function of the foot and a normal gait 7,8.
articuladion That same day was attended at the Emergency Room ER and after a physical exam and X rays is diagnosed with a sprained ankle. In conclusion, handling Chopart injuries is challenging and even more in the delay setting.
We recommend using orthotic insoles providing longitudinal arch support in order to prevent loss of reduction after starting to walk. Clin Biomech ; She was immobilized with a cast and cited at the ambulatory trauma service. Nineteen-year-old woman who came to our ambulatory articklacion service with the diagnosis of a sprained right ankle for evolutionary control.
An alternative to this method of treatment may be external fixation, especially given the existence of serious chopary tissue injury or when the lateral and medial columns are seriously fractured and shortened.
Articulation de Chopart
Given the poor evolution, with persistent pain and walking impairment, the patient returned to the ER at 6 weeks of the trauma suffered. She was treated with a bandage and acetaminophen 1 gram every eight hours and was allowed ongoing support weight bearing using two crutches. Another important marker of midfoot injury is the S-shaped Cyma line on lateral radiographs, sign of congruence of the talonavicular and calcaneocuboidal joints. Introduction The midtarsal joint constitutes the anatomic limit between hindfoot and midfoot.
In the supine position, under general anesthesia, access to the midtarsal joint was performed through a two-way medial and lateral approach. Main and Jowett 11 attempted to classify these injuries into five types according to the direction of the deforming force and the resulting displacement: Injuries of the midtarsal joint. Exercises that strengthen and stretch the gastrocnemius should be emphasized to the patient.
The nutcracker fracture of the cuboid by indirect violence.

The midtarsal joint constitutes the anatomic limit between hindfoot and midfoot. It is composed of the condyloid talonavicular joint and the saddle-shaped calcaneocuboidal joint. Clinical rating systems for the ankle-hindfoot, midfoot, hallux, and lesser toes. The main causes of midtarsal dislocation are motor vehicle accidents and falls from a height 3,9.
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 management it is not well defined. Chopart midtarsal joint dislocations are relatively rare but potentially serious injuries.
Obtaining radiographs of articklacion foot in three projections articulcaion, lateral and oblique is ve. 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.
Main Bj, Jowett Rl. Tibiotalar joint mobility was preserved, and no painful. Kirschner wires in appropriate cases are left equally implanted during this period.
