A crosspiece for use in forming a link or frame to embrace a group of segments of a spinal column in the treatment of spinal disorders has a pair of tubular side members joined by a spacing member intermediate their ends and the axes of the tubular side members and the axis of the spacing member are coplanar. A pair of crosspieces can be combined with a pair of rods to form a link or frame which will cater for spinal growth. The rod members can be plain rods or L-shaped rods or ratchet rods or combinations thereof. The bores in the tubular through bores are closed ended.
