1. A length-adjustable strut assembly comprising:
an externally threaded rod portion including a first externally threaded rod member;
a strut barrel assembly including a strut barrel portion with an internal cavity and an adjustment portion, the rod portion extending within the internal cavity of the strut barrel portion and selectively threadably coupled with at least one key of the adjustment portion;
a first joint assembly at an end of the first externally threaded rod member, the first joint assembly configured to removably couple to a first platform and allow angulation and rotation between the first externally threaded rod member and the first platform;
a second joint assembly at an end of the strut barrel portion, the second joint assembly configured to removably couple to a second platform and allow angulation and rotation between the strut barrel assembly and the second platform, and
wherein at least one portion of the second joint is configured to be selectively disassembled from the end of the strut barrel portion to expose the internal cavity of the strut barrel portion and an end of the rod portion,
wherein selective rotation of the adjustment portion rotates the strut barrel portion, and wherein rotation of the strut barrel portion rotates the at least one key about the rod portion to thereby adjust an axial length of the strut assembly between the first and second joint assemblies.
