摘要：
The present disclosure provides an external fixation strut for an external fixation device having a ball joints that can be attached to the outer or inner surface of the ring and locked to increase overall stability of the external fixation device. Some embodiments of the fixation strut include a first ball joint coupled to a first end portion of a strut housing, the strut housing having an axial bore defined therethrough. A second ball joint is coupled to a second end portion of an elongated member. The elongated member is coupled to an adjustment mechanism, which is coupled to an upper end portion of an adjustment sleeve. The adjustment sleeve is slidably disposed in the axial bore of the strut housing, and is used to effect coarse strut length adjustments. Gradual strut adjustments are effected by translating the elongated member.
