Due to the complex anatomy of the knee joint, its proximity to nerves, vessels, ligament structures and muscles, there is a wide range of possible complications and associated lesions. Luxation fractures and comminuted fractures, which occur in young patients in the context of high-speed traumas, are often associated with ligament lesions and injur...
This paper reviews the epidemiology and fracture classification of supracondylar fractures of the femur. Supracondylar fractures comprise between 4% and 31% of all femoral fractures. The incidence is 4.5/105 per year, with a prevalence of 0.4%. Supracondylar fractures typically result from high-energy trauma, such as motor vehicle accidents, in you...

Background:
Calcaneal malunions lead to a considerable loss of global foot function through the loss of the physiological hindfoot lever arm, bony and soft tissue impingement, and involvement of the subtalar joint. In the majority of cases correction of the malunion has to be combined with subtalar fusion because of a rapid development of posttrau...
Hintergrund
Da fehlverheilte Metatarsalia bei nicht axial belasteten, vor- und nachgeschalteten Gelenken nur selten operative Korrekturen erfordern, sind dennoch, wie an diversen Fallbeispielen gezeigt, operative Korrekturen bei schmerzhaften Pseudarthrosen, besonders des 5. proximalen Metatarsale zur Schmerzbehebung nicht allzu selten notwendig....

The use of locking plates has become wide-spread in the United States since the utility in the femur and tibia has been demonstrated. Specifically, the use of these plates in the foot and ankle has also become pervasive. The locking plate technology has morphed into anatomic site–specific locking plates in the foot and ankle. As one would expect, t...
Tendinosis of the Achilles tendon is a degenerative-reparative structural change of the tendon with microdefects, increases in cross-section due to cicatricial tendon regeneration, neoangiogenesis and reduction of elasticity. The previously used term tendinitis is only rarely used for the chronic form since signs of inflammation such as redness and...
Transfer of the flexor hallucis longus (FHL) tendon is an established method to replace a dysfunctional Achilles tendon. When using a single incision, the FHL tendon has to be transferred as a single stranded graft into the calcaneus and the distal FHL stump cannot be directly attached to the flexor digitorum longus tendon (FDL). Another concern wi...
