Leventhal's 1951 paper asks a foundational question: can titanium serve as an inert, mechanically adequate metal for surgical implants? Using rabbit subcutaneous tissue and rat femora, he evaluates tissue reaction, bone response, corrosion resistance, and material properties against the stainless-steel alloys then dominating fracture fixation.
Every titanium fracture plate, intramedullary nail, and cementless femoral stem used today traces its scientific legitimacy to this 2-page paper. Leventhal identified the two properties that define titanium's surgical value: biological inertness in soft tissue, and the tendency for bone to fuse with it over time.
That second property — initially flagged as a potential drawback for temporary implants. Became the cornerstone of cementless arthroplasty and dental implantology once Brånemark formalized osseointegration in the 1960s–70s.
When you choose titanium over stainless steel for a fracture plate or an uncemented femoral stem, this paper is the experimental basis for that decision: proven inertness, superior strength-to-weight ratio, no eddy current risk, and a reliable capacity to bond with host bone.
