The patella is the largest sesamoid bone in the body. As the patella bone is responsible for the strong extensor mechanism of the knee joint, its reconstruction and anatomical restoration after fracture is always desirable over excision. Extra articular fracture of lower pole of patella accounts for less than 10 percent of all patellar fractures. The treatment of these fractures is complicated,...

MR imaging of the cervical spine is valuable for assessing traumatic injuries to the spinal cord and bony ligamentous structures. MR is also useful for detecting such long-term complications of spinal cord injury as syrinx, arachnoid cyst, cord adhesion, and persistent mechanical impingement on the spinal cord or spinal nerve roots. Treatment of cervical spine injuries that are mechanically uns...

PURPOSE Tension band wiring is commonly used for fixation of simple transverse fractures. The popular configuration is parallel Kirschner wires (K-wires) and a stainless steel wire loop placed in a vertically oriented figure-of-8. METHODS We used a wooden model of a patella with a midway transverse fracture and compared four different types of fixation. The first construct had a vertical figu...

The hybrid fixators, or the fixators that use the thin wire fixation in the periarticular fragment combined with the half-pin fixation in the diaphysis, have made the multiplanar external fixation easier to use and thus growing in popularity. However, the configuration of the ideal hybrid has not been elucidated yet. The purpose of this study was to determine the stiffness characteristics affec...

A sixty-year-old man was admitted due to chest pain. He had a history of pelvic bone fracture fixation with Kirschner wire about 20 years earlier. On examination, we detected a Kirschner wire that had migrated into the right ventricle. Without cardiopulmonary bypass, we removed the migrating Kirschner wire via median sternotomy. The patient recovered without complications and was discharged on ...

Migration of Kirschner wires after fracture fixation is a rare complication. Several cases of intrathoracic migration after humeral or clavicle fixation with this technique have been reported though. We describe an even rarer case where a wire migrated from the proximal humerus to the abdomen perforating the left thoracic cavity and hemidiaphragm. The distal end of the wire was located next to ...

Management of type II distal clavicle fractures has always been a challenge. Non-operative treatment has a high risk of complications and should be considered only for elderly and frail patients. For younger and active patients there is a wide variety of operative options, each with advantages and disadvantages. According to our unit's experience the first choice could be hook plate fixation, w...

Wire breakage and migration is a known complication of using a wire tension band construct to treat displaced patella fractures. We report a case of a broken K-wire that migrated from the patella completely into the proximal tibia without complication 9 years after the index surgery. This report highlights the fact that wire migration can occur long after fracture healing and be relativel...
