Foot Anatomy and Biomechanics

Then it proceeded to carefully repair capsulo-ligamentous structures. The cjopart Chopart-Lisfranc lesion seems to present significantly worse results. 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.

Open reduction and internal fixation is the most precisely method restoring the anatomy and thus gets the best functional outcomes. Inveterate dislocations are also an indication of open reduction.

Firstly the reevaluation of emergency radiographs was performed, finding a midtarsal joint plantar dislocation and an associated calcaneal fracture that had gone unnoticed Fig. Chopart midtarsal joint dislocations are relatively articulaxion but potentially serious injuries. Discussion The midtarsal is a low mobile but essential joint for proper mechanics and architecture of the foot.

The first aim articuoacion to present the case and its treatment. Under fluoroscopic control it was performed percutaneous osteosynthesis with Kirschner wires through both joints.

Articulation de Chopart

Obtaining radiographs of the foot in three projections anteroposterior, lateral and oblique is essential. Lisfranc and Chopart injuries. Foot Ankle Int ; J Foot Ankle Surg ; The patient had no foot pain either at rest or walking, but referring articulavion functional limitation when running.

Clinical rating systems for the ankle-hindfoot, midfoot, hallux, and lesser toes.

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. Foot ankle Int ; According to Klaue 10 we thought the double approach is the best way to treat these injuries by ensuring accessibility to both joints.

A midtarsal joint dislocation in a year-old-woman is described, in which diagnosis was performed at 8 weeks of evolution. Delay in diagnosis is common and may adversely affect the long-term prognosis 3. The heterogeneity and complexity of midtarsal dislocations and fracture-dislocations hampers the existence of an international consensus classification.

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. 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. The frequency is by far the highest for the medial and plantar dislocations.


J Orthop Surg Hong Kong ; The midtarsal is a low mobile but essential joint for proper mechanics and architecture of the foot. In most of the cases are due to axial loads or torsional forces acting on the foot in plantar flexion.

Chopart fractures and lisfranf. 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.

The injury severity was reported to lisfrabc patient and a surgical reduction of the dislocation was scheduled for two days later. There are not great differences in prognostic terms comparing pure dislocations and fracture-dislocations.

Arch Orthop Trauma Surg ; 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.

Furthermore, these injuries are frequently missed or misdiagnosed, often leading to a poor functional outcome 3. Given the poor evolution, with persistent pain and walking impairment, the patient returned to the ER at 6 weeks of the trauma suffered. The nutcracker fracture of the cuboid by indirect violence.
