Titanium implant for the osteosynthesis of massive allograft reconstruction to improve follow-up by magnetic resonance imaging.

In twelve patients with local aggressive or malignant bone tumors allograft reconstruction after limb sparing procedures were performed using titanium implants for osteosynthesis. In eleven of these patients magnetic resonance imaging studies could be completed. Distortions of the images were limited to the vicinity of the implants and did not preclude detailed analysis of the gross anatomy and of fine articular structures involving and adjacent to the allografts used. Titanium implants therefore can be recommended whenever magnetic resonance imaging can be anticipated to be of importance for follow-up studies, such as after limb saving procedures for malignant musculoskeletal tumors. Aspects of high interest and importance in such cases include early recognition of local recurrence, bone fusion and healing of soft tissue structures, incorporation of allografts, and viability of cartilage.
