Bone marrow pressure chamber: a permanently inserted titanium implant for intramedullary pressure measurements.
We describe a titanium implant for repeated intramedullary pressure measurements. The implant has been inserted permanently in the tibia of rabbits. Pressure is transmitted through a membrane in the chamber to a transducer connected to a meter. During the recordings no penetration of the cortex is necessary. The measured intact intramedullary pressure in the tibia was approximately 12 cmH2O.
