Medical devices having one or more rotatable linkable components or segments, delivered in a first orientation relative to a component guide into a tissue cavity, such as the interbody vertebral space. After delivery, each segment may be rotated to a second, different orientation relative to the component guide, such as into a permanent vertical standing position. The segments achieve maximum distraction of the cavity space such as adjacent vertebra end plates, while using a minimal invasive surgical (MIS) approach. When the segments are tightened in place, the device provides long-term stability. The device can be used as a distraction instrument and/or permanent implant that can be used for interbody fusion, nuclear replacement, or anywhere in the body where a stable distraction of tissue and/or the implantation of material such as a device with an MIS approach is desired.
