Alterations in the immune response after multiple trauma, posttraumatic sepsis and surgery are recognized as physiological reactions of the organism to restore homeostasis. The level of these immunological changes correlates with the degree of tissue damage as well as with the severity of haemorrhage and ischaemia. Cytokines are known to be integral components of this immune response. ⋯ Therefore, in several clinical studies, cytokine levels during the posttraumatic course have been determined with the aim of finding predictive markers of patient outcome. The purpose of this review was to highlight our current knowledge on the interaction of posttraumatic immune reactivity and the development of complications. A better understanding of these mechanisms might lead to the introduction of preventive and therapeutic strategies into clinical practice.

At last, flexor tendon injuries of the hand and digit are no longer nearly impossible to treat. Many recent studies have reported a more than 75% success with excellent results, in particular in zone 2, in some cases reaching 98% satisfactory outcomes. The challenge inherent in treating and rehabilitating the zone 2 flexor tendon injury remains, however, even for the skilled hand surgeon. We must remain diligent, obeying principles outlined earlier by the first surgeons willing to attempt these repairs, while carefully gleaning the helpful and critical recommendations of the now sophisticated researchers in the subject of flexor tendon repair and rehabilitation.

Comparative Study Controlled Clinical Trial
[Treatment of mid-clavicular fractures in adults. Early results after rucksack bandage or elastic stable intramedullary nailing].
The aim of this prospective study was to compare the results achieved in two groups of patients treated for mid-clavicular fracture. ⋯ Intramedullary nailing of mid-clavicular fractures is a safe and minimally invasive operation technique. Early functional and cosmetic results are not worse than results after nonoperative treatment with a rucksack bandage.

Although screw or plate fixation of the fractured calcaneus was first described in the 1920s, surgical treatment using open anatomical reduction and stable internal fixation only commenced at the start of the 1980s. This treatment was made possible by the introduction of new imaging methods such as CT which allowed better detection of the fracture pathology and provided the basis for new surgical strategies. New procedures, including modified surgical approaches related to vascular anatomy, arthroscopic control of the subtalar joint during open or closed reduction, early free flap coverage in severe open or closed fractures with full-thickness skin necrosis, increasingly available (3)D intraoperative radiographic monitoring, and the use of interlocking calcaneus plates, have significantly improved the functional outcome in the treatment of fractures of the calcaneus.

Clinical Trial
[ACL reconstruction with bone-patellar tendon-bone graft and proximal fixation with the EndoButton: a 2- to 5-year follow-up].
Interference screw fixation in ACL reconstruction with bone-patellar tendon-bone graft (BPTB) is a potential source of intraoperative complications such as graft laceration. Further problems are artifacts on MRI and screw removal in revision surgery. These problems can be avoided by using distant fixation with the EndoButton. We designed this study to evaluate the clinical as well as the subjective outcome of ACL reconstruction with BPTB graft and femoral fixation with the EndoButton. ⋯ The clinical outcome of ACL reconstruction with EndoButton fixation is comparable to other studies on ACL reconstruction with interference screw fixation. However, since the EndoButton avoids potential problems of the interference screw fixation, we recommend this fixation technique for ACL reconstruction with BPTB graft.
