Distal tibial fractures can be divided by mechanism into injuries caused by torsion trauma or by compression trauma. The latter ones are often associated with a complete destruction of the tibial joint surface, so-called tibial plafond fractures. Another group of fractures are the distal metaphyseal fractures of the tibia with only minimal involvement of the ankle as a result of low energy torsion trauma. ⋯ Fractures with severe soft tissue injury should be initially fixed with an external fixator. Definitive fixation and reconstruction should here be performed in subsequent operations. Early functional therapy can be attempted if fractures are reliably stabilized.

Controlled Clinical Trial
[Computer-aided discectomy and corpectomy in anterior reconstruction of the injured thoracolumbar spine. A prospective, controlled clinical trial].
In anterior reconstruction of the unstable thoracolumbar spine, discectomy and corpectomy are technically demanding steps requiring maximal surgical precision. This study investigated the feasibility of computer-aided guidance for discectomy and corpectomy. It also analysed the precision, advantages, and disadvantages of the procedure. ⋯ Computer-aided guidance for anterior reconstruction of the thoracolumbar spine is a technically feasible option that may help in performing discectomy and corpectomy. However, this technique significantly prolongs the operating time. There were no differences in the precision of implant positioning between the groups. However, during discectomy the use of computer navigation may possibly add to the protection of adjacent end plates.

Case Reports
[Calcaneonavicular coalition fracture. A rare differential diagnosis of post-traumatic ankle pain].
The causes of chronic posttraumatic ankle pain are manifold, ranging from ligament and tendon injuries and fractures to joint degeneration. Calcaneonavicular coalition, a bridge between the calcaneus and navicular bones, is a rare disease with an incidence below 1%. The morphology of this coalition is variable. ⋯ Symptoms usually occur in adolescence with chronic pain around the ankle, mainly lateral and anterior, following distortion trauma. Patients often claim to have a lateral ankle sprain. We report 2 cases of a fracture of the calcaneonavicular coalition as the cause of chronic posttraumatic ankle pain and demonstrate the characteristics of tarsal coalitions with a review of the literature.

Case Reports
[Pseudoaneurysm - a rare complication after insertion of a distal locking bolt of an intramedullary femur nail].
A pseudoaneurysm is caused by an extravasal hematoma after vessel injury. Persistent blood supply via the afferent artery can lead to aneurysm growth with potential rupture of the lesion. ⋯ Successful treatment consisted of endovascular embolization (coiling) with injection of a platinum coil into the aneurysm's supplying vessel. Pseudoaneurysm after fracture or fracture fixation represents a rare complication, but the risk of acute bleeding by pseudoaneurysm rupture should not be neglected.
