Dislocations of the foot are uncommon but potentially incapacitating injuries. The mechanism of injury may vary from a simple fall to a major motor vehicle collision (MVC). The foot is a complex structure, and injuries often occur in patients who sustain multiple trauma. The clinician must understand common patterns of injury and maintain a high index of suspicion in examining the appropriate radiographs to avoid missing foot dislocations.

Injuries of the Mid-Tarsal Joint

Main and Jowett — 2010-11-02 07:01:32 GMT

Injuries involving the midtarsal joint, which are frequently misdiagnosed, have been studied to clarify the mechanism, classification and treatment. The necessity for routine antero-posterior, lateral and oblique radiographs is emphasised. Seventy-one injuries have been classified according to the direction of the deforming force : medial,longitudinalcompression,lateral, plantar and crush types are described. Included in the medial and lateral types is a hitherto undescribed tarsal rotation or “swivel” injury. The mechanism whereby longitudinal compression causes fractures of the body of the navicular is described, and two varieties having different prognoses are defined : one due to purely longitudinal compression and the other due to longitudinal compression with a medial component. The results of treatment have been assessed clinically and radiologically. Reduction, open if necessary, with internal fixation, is recommended for displaced fractures : primary arthrodesis is not indicated. For severe persistent symptoms from medial and longitudinal force injuries triple arthrodesis is recommended, and from lateral force injuries, calcaneo-cuboid arthrodesis.

Lisfranc injury caused by a pedal brake perforating the foot

Kacou et al — 2009-05-26 07:01:32 GMT

T he tarsometatarsal joint or Lisfranc joint is a complex articulation whose stability is provided by the osseous, capsular and ligamentous attach- ments. Lisfranc lesions (LFLs) are commonly fracture-dislocations of the Lisfranc joint and are generally caused by high-energy trauma.1 Since publica- tion of the classification of LFLs by Hardcastle and colleagues,2 based on the work by Qenu and Kuss, many papers have dealt with their anatomic patterns, treatment and prognosis, each of which is open to questions. However, the main area of controversy has been the modalities of surgical stabilization.2–4 We report the case of a patient with fracture-dislocation of the Lisfranc joint, treated surgically with the use of K-wires, in which the mechanism of injury was unusual.

Medial swivel dislocation of the talonavicular joint

Datt et al — 2010-11-02 07:01:32 GMT

Medial swivel dislocation, a variant of subtalar dislocation is uncommon. A 35 years old male presented after 6 weeks old injury to left ankle following motor cycle accident. He had pain, swelling around ankle and was unable to bear weight on left foot. Clinical examination revealed diffuse swelling and tenderness in mid foot region. His plain X rays and CT scan showed talonavicular dislocation with compression defect of the head of the talus. He was treated by open reduction and K-wire fixation. At 32 months follow up foot was painless, stable with normal range of ankle and subtalar motion.

Turf Toe Dislocation of MTP Great Toe Wheeless

C.R.Wheeless — 2002-01-31 07:01:32 GMT

Turf Toe is a tear of joint capsule from MT head which results in subluxation or dislocation of first MTP joint
- caused by hyperextension (most common), hyperflexion, or valgus injury;
- associated with decreased ROM at first MTP joint & its sequele can include hallux rigidus, and can exacerbate sesamoiditis;

Turf Toe eMedicine Orthopedics

Ohlson & O'Connor — 2008-03-31 07:01:32 GMT

Although several variations exist, the classic definition of turf toe is a hyperdorsiflexion injury of the first metatarsophalangeal (MTP) joint. Since approximately the 1980s, turf toe has received increased attention in the media because of its effect on college-level and professional athletes.
