The rising incidence of osteoporotic fractures requires novel treatment strategies. ⋯ Implant augmentation offers high biomechanical potential to prevent mechanical complications after fracture fixation in osteoporotic bone. Early and confident mobilization of elderly patients therefore appears to be possible. With appropriate handling, associated risks seem controllable; however, implant augmentation cannot be applied as a routine concept for osteoporotic fracture management. The application requires careful evaluation on a case by case basis under comprehensive consideration of mechanical and biological factors.

Proximal femur fractures are common and treatment is expensive. The aim of the present study was - after matching of hospital and health insurance data - to evaluate the influence of early operation on certain outcome parameters. Data from a German health insurance were used to identify then influence of the day of operation after admittance on the rate of mortality, decubitus, and revision surgery during the hospital stay and on the care level of the patients up to 1 year and in some cases longer after operation. ⋯ The present study clearly presents the importance of analysis of routine records after discharge and it demonstrates that longer periods up to 1 year and more can be evaluated. The data show that a longer time period between hospital admission and operation negatively influences all outcome parameters. The care data give impressive evidence for a significant loss of quality of life and the importance of intense postoperative rehabilitation.

We report on two cases of posttraumatic ileus after pelvic ring fracture in two patients aged 73 and 74 years, respectively. Although all conservative measures were exhausted, in both cases the ileus resulted in additional operative procedures and a significant extension of the hospital stay. ⋯ Only the trauma-related motility disorder led to a clinical manifestation. Pathophysiological mechanisms and their implications on prophylaxis and therapy are discussed.

Case Reports
[Bony avulsion of the extensor carpi radialis longus tendon from the base of the second metacarpal : A rare injury.]
We report on a 19-year-old male patient with a rare injury: a basis fracture of the second metacarpal with avulsion of the extensor carpi radialis longus (ECRL) tendon. The patient was treated with open reduction and internal plate fixation of the fragment. The functional results after 10 months of follow-up were pronation/supination 90/0/90° (90/0/90°), extension/flexion 70/0/70° (70/0/70°) radial/ulnar duction 20/0/40° (25/0/40°), bilateral grip strength was 115 kPa. ⋯ The Mayo wrist score reached 100 points. Radiologically, the fracture was consolidated. Consistent diagnostics and surgical therapy lead to functional and radiological recovery following fracture of the second metacarpal base with avulsion of the extensor carpi radialis longus tendon.

Cements based on polymethyl methacrylate (PMMA) can be used without any problem in a variety of clinical augmentations. Cement-related complications in surgical procedures involving PMMA cements, such as embolism, thermal necrosis, toxicity and hypersensitivity, are often due to other causes. Knowledge about the properties of the cement helps the user to safely employ PMMA cements in augmentations. ⋯ In patients with hypersensitivity to antibiotics, there is no need to avoid the use of PMMA as there are sufficient PMMA-based alternatives. The PMMA cements are local drug delivery systems and antibiotics, antiseptics, antimycotics and also cytostatics can be mixed with the cement. Attention must be paid to antagonistic and synergistic effects.
