High-strength, anodized aluminum circular fixation rings are available in full, 5/8, 1/3 arches, stretch, D2, and spinal arches. Utilized to provide frame design simplicity.

Full Rings
Basic building blocks of the IMEX™ circular ESF system.

5/8 Rings
Can be closed with 1/3 arch. Typically used alone to avoid anatomical constraints.

1/3 Ring Arches
Can be utilized alone as a supporting element, or can be utilized to close a 5/8 ring or stretch ring if additional mechanical properties are desired.

Stretch Rings
Popular around hock and elbow to allow range of motion without a larger ring diameter being used. Can be closed with a 1/3 ring if desired.

D2 Rings
D2 rings feature a dual hole pattern. These rings are useful for a variety of hybrid frames and one may be included in some true circular frames. The inner diameter and inside hole pattern are the same as standard full rings. The outer hole pattern features many choices for maximum flexibility and is not compatible with the IMEX™ hybrid adapter. Spacing between hole patterns allows addition of wire fixation bolts, hinges or other hardware at an otherwise unavailable position.

Spinal Arches
A structural element for the IMEX™ Circular ESF System. The large radius of the spinal arch allows temporary or permanent placement of fine wire or hybrid frames along the spine for reduction or repair of spinal injuries. Often used with part number 2.80001 (small SK™ clamps for 6mm threaded rod).
