Systeme des endoprothetischen Gelenkersatzes des Großzehengrundgelenkes

We compare the different systems for a joint replacement of the first metatarsophalangeal joint. The main aim for the development and redesign of the different arthroplasty systems was to restore the anatomic and physiological function of the foot when the metatarsophalangeal joint is destructed. Former types of implants like spacers often had problems with osteointegration or biological reactions. The up to date modular implant systems allow the surgeon to perform an anatomic and functional arthroplasty or hemiarthroplasty which fit the different patient requirements and have good long term results. The authors compare different implants and their advantages and disadvantages in context of their development over the last years.
