The distal radius is one of the commonest sites of fracture, and this injury is sometimes associated with fracture of the distal ulna. In recent years, surgical treatment of distal radius fractures has consisted increasingly in internal fixation with locking plates followed by early functional postoperative treatment. The associated injury to the distal ulna has so far not received much attention in the literature. ⋯ No length differences of more than 2 mm and no functionally relevant deviations of the ulnar axis were observed. Apart from 3 cases of nail perforation at the distal end of the ulna, which had no clinical manifestations, there were no complications. ESIN offers a minimally invasive option for the treatment of unstable fractures of the distal ulna associated with distal radius fractures; it allows functional aftertreatment and can be regarded at least as an alternative to open reduction with internal fixation.

Proximal fracture of the humeral head is the third most frequent fracture in humans. Most (70%) of those affected are over 60 years old. It is hoped that advanced locking medullary screws or plates will reduce the risk of secondary dislocation of screws or fracture segments when the bone of the humeral head is osteoporotic. ⋯ The new implant provides superior stability in the fixation of humeral head fragments and has proved its worth in everyday clinical practice when additional indirect fixation of the tubercle is needed, as it frequently is in elderly patients.

The purpose of this study was to assess the risk of knee injuries among vulnerable road users, such as pedestrians, bicyclists and motorcyclists. ⋯ The highest risk for knee injuries among vulnerable road users is encountered by motorcyclists followed by bicyclists and pedestrians. Over time, the knee injury risk for pedestrians could be significantly reduced due to aerodynamic changes of current car fronts. Further modification of the exterior car design might decrease the risk for knee injuries among vulnerable road users.

Dislocated combined injuries of the upper cervical spine such as C 1/2 fractures require occipitocervical fusion, especially if the dislocation can not be redressed using halo vest immobilisition. We report on the clinical course and outcome of a young woman who sustained complex cervical spine injuries. Closed reduction and a percutaneous transfixation of C 1/2 with k-wires (Magerl) and an additional halo vest immobilisition was performed to avoid permanent fusion. ⋯ Complex injuries of the upper cervical spine that cannot be retained by external fixation often require an occipitocervical fusion or fixation of C1/2. In the case presented, the temporary percutaneous fixation (Magerl) with k-wires was terminated after 3 months to avoid significant functional impairment. Younger patients benefit most from temporary fusion of the upper cervical spine, which results in better functional outcome and only minor pain.

Midfoot injuries of children are rare entities and often caused by high energy trauma mechanisms. Foot fractures in children may pose a diagnostic challenge but they usually have a good prognosis. In special cases computed tomography is necessary to find the right diagnosis in addition to plain X-rays. Based on two cases of midfoot injuries, a type II open Lisfranc fracture dislocation and a dislocation of a Chopart's joint, we describe the causes, diagnosis, and possibilities for treatment of juvenile midfoot injuries.
