Key result
During prosthetic hip surgery, impaction of the femoral prosthesis caused a significant drop in arterial oxygen tension that strongly correlated (r = -0.97) with lung 125I deposition.
Why the study?
Does prosthetic hip surgery by the Charnley method induce pulmonary microembolism and dysfunction in patients?

Does prosthetic hip surgery by the Charnley method induce pulmonary microembolism and dysfunction in patients?
Effect estimate: Correlation coefficient -0.97
Prosthetic hip surgery by the Charnley method is associated with intraoperative pulmonary microembolism and a significant reduction in arterial oxygen tension.
Modig et al. (1974) conducted an observational in Prosthetic hip surgery. Prosthetic hip surgery (Charnley method) was evaluated on Deposition of 125I radioactivity in the lung and arterial oxygen tension (PaO2) reduction (Correlation coefficient -0.97). During prosthetic hip surgery, impaction of the femoral prosthesis caused a significant drop in arterial oxygen tension that strongly correlated (r = -0.97) with lung 125I deposition.
