Postoperative bone density changes with the MiniHip™ short-stem prosthesis

With the introduction of short-stem endoprostheses over the last decade the range of indications has been increasingly expanded to include a significantly younger patient population although long-term results are scarce. In addition to bone preservation during primary implantation the concept of short-shaft prostheses also focuses on better reconstructability of the individual patient's anatomy and the long-term osteological competence of the implants with the aim of achieving a longer service life. Numerous clinical and radiological studies support the use of short-shaft prostheses. The MiniHip™ has shown good results in early and medium-term clinical outcomes to date. Radiological follow-up examinations for an interpretation of the long-term prospects of success are still pending. The aim of this study was to evaluate the osseous integration of the cementless MiniHip™ short-stem hip endoprosthesis and its influencing factors.
