Provided herein is a
system (1000) for assisting a surgical intervention on a bone of a subject comprising: - a jig holder (100), JH, comprising at least one JH bracelet (112, 142) wherein each JH bracelet (112, 142) comprises: - a longitudinal JH bracelet body (114, 144) having a proximal end, a distal end, a central direction towards a central longitudinal axis (A-A'), and a
peripheral direction away in a
perpendicular direction from the central longitudinal axis (A-A'); - a JH passageway (116, 146) disposed in the JH bracelet body (114, 144) between the proximal end and the distal end, and having a shape complementary to a target region of the bone of the subject for the surgical intervention; - a JH
coupling region (118, 148) comprising a ring of exterior surface of the JH bracelet body (114, 144) for repeatable dismountable
coupling to and alignment with a jig (200); wherein each JH bracelet body (114, 144) has an assembled state (114ASM, 144ASM) and disassembled state (114DASM, 144DASM), wherein: - each JH bracelet body (114, 144) comprises a plurality of JH bracelet body segments (144a; 144b); - the plurality of JH bracelet body segments (144a; 144b) of each JH bracelet body (144) in the disassembled state (114DASM, 144DASM), co-operate to form the assembled state (114ASM, 144ASM) for a form-fit
coupling by the JH passageway (116, 146) to the target region of the bone of the subject for the surgical intervention; wherein each JH bracelet
body segment (144a; 144b) is a longitudinal segment of the JH bracelet body (114, 144).
