Development of a new modular titanium femoral prosthesis consisting of a head and shaft component. Indications, operation and optimization of the tapered socket connection

Abstract

Summary: The development and clinical indications of a new modular femoral endoprosthesis consisting of a head and shaft component is discribed. Components are available in different lengths and diameters and therefore can be joined individually depending on the patients anatomy and surgery required. Both parts are joined by a unique optimized taper socket with a groove, avoiding fretting and corosion. Fatigue tests showed no loosening of the tapered connection and no prosthesis fracture. The material and surface structure as weU as the philosophie of the distal fixation are discussed.

Outcome of Trochanteric Femoral Fracture Treatment with Gamma Nail Procedure is Independent of Bone Density

“…If, however, the femoral fracture is combined with osteoarthrosis of the hip, arthroplasty should be performed and the fracture stabilized in one operation. This procedure shows comparable results to the use of the gamma nail [1].…”

Experience with a modular hip prosthesis consisting of a separate head and shaft component in patients with femoral bone defects

“…Eine Konussteckverbindung sichert die Verbindung zwischen Kopf-und Schaftteil ohne die Gefahr des Frettings [1]. Durch die unterschiedlich dicken und langen Schaftanteile zeichnet sie sich somit durch die Kombination aus Marknagel und Htfftprothese aus.…”
