The requirements for treatment of femoral fractures are increasing with the rising age of the patients. The aim of this study was to evaluate femoral stiffness and the fracture risk after inserting different implants and implant combinations. ⋯ Taken together these results clearly indicate that a hip prosthesis significantly weakens the femur, whereas two stems produce the most stable situation at all. The situation of a hip prosthesis and an retrograde nail should be avoided or covered by a bridging-osteosynthesis. In clinical practice an extramedullary fixation technique for distal femoral fractures should be preferred.

Today, lumbar disc disease is a very common disease, which will be often seen in both the family practice as well as in the consultations of orthopedics, neurology, rheumatology or neurosurgery. Furthermore, lumbar disc surgery is one of the most common spinal surgical procedures worldwide. But, for many centuries, physician had no clear understanding of the anatomical condition and the pathomechanism of this disease. ⋯ In 1742, a contemporary of Cotugno, the German Josias Weitbrecht (1702-1747) has to be credited for the first precise description of the intervertebral disc. Nearby a hundred years later, the German Hubert von Luschka (1820-1875) described for the first time a herniated disc in a pathologic specimen. With the landmark report of the New England Journal of Medicine in 1934, the two American surgeons, William Jason Mixter (1880-1958) and Joseph Seaton Barr (1901-1963), finally cleared the pathomechanism of lumbar disc disease.

This article presents a retrospective look at spinal implants of the 1970s and 1980s. ⋯ The basic principle of spinal fixators (internal and external) is contained in the complete product range of dorsal stabilizing implants from practically all manufacturers worldwide and has become taken for granted.
