Unusual Supero-Lateral Dislocation of Intact Bilateral Mandibular Condyles Associated with Right Parasymphysis Mandibular Fracture:A Case Report and Review of Literature

The dislocation of the mandibular condyle / condyles occurs most commonly in an anterior direction due to trauma. This is a known fact as due to pull of lateral pterygoid muscle. On the contrary, posterior, superior, or lateral dislocations of the intact mandibular condyle occur rarely, and very few such cases have been reported in the English language literature. The rarity of these dislocations can be attributed to the varying anatomy of the condyle, the direction of pull of muscles attached to the condyle and low incidence of skull base fractures from an indirect blow. A case of bilateral supero-lateral dislocation of the condyle associated with a symphyseal fracture is presented. We discuss the dynamics, diagnostic features and clinical management of such dislocations with extensive review of literature

Reduction of superior-lateral intact mandibular condyle dislocation with bone traction hook

Lateral and superior-lateral dislocations of the intact condyle are a rare complication, following traumatic insult to the mandible. We report an unusual case of a 54-year-old male patient who experienced both types of dislocations of the intact condyles with symphysis fracture following a road-traffic accident. Under general anesthesia, conventional manipulation was unsuccessful in relocating the condyles into the glenoid fossa. After applying a percutaneous traction force, using a bone traction hook placed at the sigmoid notch, the displaced intact mandibular condyles were repositioned, and the symphyseal fracture was finally reduced and fixed. The mouth opening was within normal limits, and favorable occlusion was confirmed one month postoperatively. To our knowledge, this is the first case of dislocation of both intact condyles--associated with symphysis fracture--being reduced with bone traction hook.

Irreducible Posterolateral Dislocation of the Knee Joint with Lateral Dislocation of the Patella: A Report of Two Cases

Reduction of the knee is impossible if the medial femoral condyle is caught in the medial soft tissue while posterolateral dislocation of the knee happens. Irreducible posterolateral dislocation with buttonholing of the medial femoral condyle through the torn vastus medialis muscle has rarely been reported. Furthermore, such a case associated with patella lateral dislocation has very seldom been reported. We report here on 2 such cases that were treated with open reduction.

Lateral Dislocation of the First Metatarsophalangeal Joint: A Case Report

Dislocation of the metatarsophalangeal joint is rare due to the stability of the ligaments and soft tissue surrounding the joint. The authors have experienced lateral dislocation of the first metatarsophalangeal joint, which required surgery, accompanied by complete injuries of medial collateral ligament and capsule, contributing to medial stability, differing from posterior dislocation with intersesamoid complex rupture, with a review of the relevant literature and previous reported cases.
