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. A midtarsal joint dislocation in a year-old-woman is described, in which diagnosis was performed at 8 weeks of evolution. Close reduction is a valid procedure in subluxations, acute dislocations when anatomy could be perfectly restored or in cases where surgery is articulacio 5,9.
Artrologia Tobillo y pie
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. Foot Ankle Int ; Both joints together with the subtalar joint afticulacion involved artjculacion in the inversion and eversion movements 5,6. At 48 hours after surgery the patient was discharged, after skin condition and postoperative radiographs were controlled.
Finally deserves special attention the combined Chopart and Lisfranc dislocation, rare but especially serious. Tibiotalar joint mobility was preserved, and no painful.
She was immobilized with a cast and cited at the ambulatory trauma service. The patient had no foot pain either at rest or walking, but referring some functional limitation when running. They can be pure dislocations i.
Another important marker of midfoot injury is the S-shaped Cyma line on lateral radiographs, sign of congruence of the talonavicular and calcaneocuboidal joints. Then it proceeded to carefully repair capsulo-ligamentous structures. 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 It exposes perfectly the calcaneocuboidal joint.

According to Klaue 10 we thought the double approach is the best way to treat these injuries by ensuring accessibility to both joints. Lisfranc and Chopart injuries.
CT offers additional choaprt when associated lesions or to plan future treatments and is not hesitating to apply if diagnosis is unclear. The first aim is to present the case and its treatment. We recommend using orthotic insoles providing longitudinal arch support in order to prevent loss of reduction after starting to walk.
Their rarity should not be a reason to underestimate them, as they are really complex and potentially serious lesions.
Exercises that strengthen and stretch the articulqcion should be emphasized to the patient. Under fluoroscopic control it was performed percutaneous osteosynthesis with Kirschner wires through both joints.
Furthermore, these injuries are frequently missed or misdiagnosed, often leading to a poor functional outcome 3.
We hope the reported case may be helpful to orthopedic surgeons facing similar cases and increasing awareness about this rare but serious entity. Joint stabilization with Kirschner wires 1,mm once the congruence is restored, may provide additional stability articculacion could be performed after either open or close reduction.
In cases of poor outcome and at the persistence of pain will be indicated salvage procedures including osteotomies and arthrodesis.
Articulation de Chopart
It requires careful dissection and protection of the peroneus superficialis and suralis nerves Fig. Definitive diagnosis after dhopart 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. The reasons for misdiagnosis could be their low prevalence and the absence of obvious radiological signs in up to a third of cases 5, Advanced balance and proprioceptive training for lower-extremity function is also important 6.
She was treated with a bandage and acetaminophen 1 articulafion every eight hours and was allowed ongoing support weight bearing using two crutches. Avulsion fracture of the dorsal talonavicular ligament: Classification and epidemiology of mid-foot fractures.
Ankle and foot injuries: Clinical rating systems for the ankle-hindfoot, midfoot, hallux, and lesser toes. 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.
Chopart fractures and dislocations. Isolated dorsal midtarsal Chopart dislocation: Introduction The midtarsal joint constitutes the anatomic limit between hindfoot and midfoot.
Greater series reported 3,7,9 agree on a set of conclusions in terms of outcomes but they all refer pisfranc acute lesions.
Often, these lesions occur in cases presenting a varus-cavus foot morphotype listranc Computed tomography CT was requested. Complex midfoot injuries could lead to severe functional impairment of mobility and quality of daily living. Inveterate dislocations are also an indication of open reduction.
Foot Anatomy and Biomechanics
In the supine position, under general anesthesia, access to the midtarsal joint was performed through a two-way medial and lateral approach. 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.
Foot Ankle Clin ; The injury severity was reported to the patient and a surgical reduction of the dislocation was scheduled for two days later. After careful debridement of fibrous interposed tissue in dhopart Chopart space, congruence of talonavicular and calcaneocuboidal joints was achieved.
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.
