[Elastic stable intramedullary nailing of clavicular midshaft fractures: comparison of open vs closed fracture reduction]. / Die elastisch stabile intramedulläre Osteosynthese der diaphysären Klavikulafraktur : Offene vs. geschlossene Reposition.

BACKGROUND: The aim of this study was to compare the outcome of open reduction versus closed reduction of midclavicular fractures using elastic stable intramedullary nailing (ESIN) in both groups. METHODS: Titanium elastic nails were used to treat 40 patients undergoing minimally invasive ESIN between December 2006 and July 2009. A total of 19 patients were treated with a closed reduction and 21 patients required open reduction. RESULTS: The Constant Score revealed no significant differences between the two groups (closed 87.4±9.0; open 85.3±7.1) nor did the DASH Score (closed: 5.0±6.5; open 5.8±7.3). The strength measurement of shoulder abduction was consistent in each group: 75.7±22.0 N in the closed reduction group and 74.2±26.0 N in the group with open treatment. CONCLUSION: There was no difference comparing right- and left-sided injuries and the outcomes were consistent irrespective of the treatment method. When appropriately indicated open and closed intramedullary nailing are very successful modalities of treatment. There were no significant differences in shoulder function after either procedure.

[Winter sports injuries of the thoracic and lumbar spine : Etiology, classification and stage-specific therapy]. / Wintersportverletzungen der Wirbelsäule : Ätiologie, Klassifikation und stadiengerechte Therapie.

BACKGROUND: Overall, spinal injuries in winter sports are extremely rare. The incidence is given as approximately 0.01/1000 ski days. While falls and collisions at high speed are the main concerns for skiers, spinal injuries for snowboarders occur primarily on landing after a jump. The age of a typical spinally injured skier is 40, which is older than that of the average snowboarder at 23. CLASSIFICATION: Primarily, the thoracolumbar junction is injured and hereby mainly anterior compression fractures (type A1) and burst fractures (types A3 and A4) occur. Injuries caused by flexion or distraction mechanisms (Type B) or rotation injuries (Type C) are less common. Injuries to the cervical spine are rare overall, but they are also represented in the very few cases with neurological deficits. THERAPY: With appropriate X­ray diagnostics, including CT and, if necessary, MRI, the appropriate therapy can be initiated so that a return to sport is possible in most cases. Furthermore, there is ongoing scientific discussion as to when conservative therapy is superior and when surgery is superior.

[Therapy-resistant tibial pseudarthrosis. Treatment success with BMP-7 combined with autologous bone]. / Therapieresistente Unterschenkelpseudarthrose. Behandlungserfolg durch BMP-7, kombiniert mit autologem Knochen.

Delayed union or non-union of long bone shaft fractures still presents a surgical challenge. Especially if there is a predisposition for pseudarthrosis such as adiposity, diabetes mellitus, local disruption of blood supply or lack of hormones, the established procedures of autologous cancellous bone grafting or plate fixation with compression often lead to insufficient results. In the following article the successful use of bone morphogenetic protein BMP-7 [recombinant human osteogenetic protein-1 (rhOP-1)], combined with autologous bone grafting for therapy of a therapy-resistant tibial non-union is described. In a patient with multiple risk factors the tibial fracture was completely cured after two attempts of osteosynthesis and autologous bone grafting had failed. The patient achieved self-mobility with full weight bearing and absence of pain 10 months after adjuvant implantation of BMP-7.

[Fractures of the lower extremity in the emergency room. Analysis of a new immobilization and x-ray splint]. / Frakturen der unteren Extremität in der Notaufnahme. Anwendungsanalyse einer Lagerungs- und Röntgenspezialschiene.

BACKGROUND: Fractures of the lower extremity are a common reason for presentation to an emergency room. The aim of this study was to evaluate a new immobilization and x-ray splint (Andante®, ForMed) in the emergency room. METHODS: From April 2010 to August 2010 all patients presenting with a fracture of the lower extremity were included in the study. Pain perception (visual analog scale; VAS) was measured before and after splint application. The handling of the splint during radiography was assessed and the quality of the diagnostic x-ray was evaluated. RESULTS: The study comprised 61 patients. Subjective pain perception was reduced significantly (3.96±1.9 vs. 6.38±2.2; p<0.001). The handling of the splint was graded at 1.73±0.96 (1, very good; 5, poor). There was no difference in the diagnostic quality of the x-rays between the Andante® and the control group; however, significantly poorer results were found for x-rays of ankle fractures (p<0.038). CONCLUSION: The Andante® splint is a useful tool in the emergency room that combines simple handling and pain relief due to immobilization. However, the quality of the diagnostic x-rays was not better compared with the control group.

[Plantar Lisfranc dislocation fracture]. / Plantare Lisfranc-Luxationsfraktur.

We report a 30-year-old patient suffering a plantar dislocation fracture after he dropped a heavy weight on his foot. The patient was treated immediately after diagnosis was secured by CT scan. Median approach and dermatofasciotomy of the foot were followed by anatomic reduction of the fractures and the Lisfranc dislocation and fixed by internal osteosynthesis. After 3 months the patient was able to ambulate pain free without walking aids. Plantar dislocation is a very rare direction of comminuted Lisfranc dislocation fractures. The outcome may be favorable with early reduction and stable internal fixation of the fractures. One always has to be aware of the major soft tissue trauma associated with complex Lisfranc dislocation fractures.
