Intra-operative gap detection

Abstract

Disclosed herein are joint implants and methods for intra-operatively detecting joint implant gap. A method for detecting a joint implant gap may include coupling a first implant to a first bone of a joint, coupling a second implant to a second bone of the joint, measuring an amplitude of a magnetic flux density using a magnetic sensor to determine a gap between the first and second implants. The first implant may include at least one magnetic marker. The second implant may be configured to contact the first implant. The second implant may include at least one magnetic sensor to detect the magnetic flux density of the magnetic marker. The gap between the first and second implant may be intra-operatively determined using the measured amplitude of the magnetic flux density.
