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. Both joints together with the subtalar joint are involved fundamentally in the inversion and eversion movements 5,6. That same day was attended at the Emergency Room ER and after a physical exam and X rays is diagnosed with a sprained ankle.

Classification and epidemiology of mid-foot fractures. Kirschner wires in appropriate cases are left equally implanted during this period.

Chopart fracture | Radiology Reference Article |

She was immobilized with a cast and cited at the ambulatory trauma lksfranc. Chopart dislocations with associated injuries, open reduction and fracture fixation represents the best option and allow reparation of damaged capsulo-ligamentous structures. At 48 hours after surgery the patient was discharged, after skin condition and postoperative radiographs were controlled. Case report Nineteen-year-old woman who came to our ambulatory trauma service with the diagnosis of a sprained right ankle for evolutionary control.


Another important marker of midfoot injury is the S-shaped Cyma line on lateral radiographs, sign of congruence of the talonavicular and calcaneocuboidal joints. The midtarsal is a low mobile but essential joint for proper choparh and architecture of the foot.

Comparing the outcomes between Chopart, lisfranc and multiple metatarsal shaft fractures. In cases of poor outcome and at the persistence of pain will be indicated salvage procedures including osteotomies and arthrodesis.

Foot Anatomy and Biomechanics

It is composed of the condyloid talonavicular joint and the saddle-shaped calcaneocuboidal joint. La importancia de reconocer las lesiones mediotarsianas. Avulsion fracture of the dorsal talonavicular ligament: 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.

Arch Orthop Trauma Surg ; Under fluoroscopic control it was performed percutaneous osteosynthesis with Kirschner wires through both joints.

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

The patient had no foot pain either cholart rest or walking, but referring some functional limitation when running. 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.

Three months postoperatively may be the time to begin normal shoe wearing 5. Finally, the avulsion fracture of the dorsal talonavicular ligament caused by additional plantar flexion forced serves as radiological marker articuladion serious ligamentous injury with midtarsal instability The midtarsal joint constitutes the anatomic limit between hindfoot and midfoot.

Hermel Mb, Gershon-Cohen J. The reasons for misdiagnosis could be their low prevalence and the absence of obvious radiological signs in up to a third of cases 5, She immediately felt local pain and swelling.

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. The nutcracker fracture of the cuboid by indirect violence. She was treated with a bandage and acetaminophen 1 gram every eight hours and was allowed ongoing support lixfranc bearing using two crutches. Open reduction and internal fixation is the most precisely method restoring the anatomy and thus gets the best functional outcomes.

Nineteen-year-old woman who came to our ambulatory trauma service with the diagnosis of a sprained right ankle for evolutionary control. Then it proceeded to carefully repair capsulo-ligamentous structures.

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