Sacrospinous ligament Sacrospinous ligament The sacrospinous ligament (small or anterior sacrosciatic ligament) is a thin, triangular ligament in the human pelvis. The base of the ligament is attached to the outer edge of the sacrum and coccyx, and the tip of the ligament attaches to the spine of the ischium, a bone in the human pelvis. Its fibres are intermingled with the sacrotuberous ligament. The sacrotuberous ligament passes behind the sacrospinous ligament. In its entire length it covers the equally triangular coccygeus muscle, to which its closely connected. The presence of the ligament in the greater sciatic notch creates an opening (foramen),
Artificial bone α-TCP is biocompatible and helps form new bone, which is better for patients in the long term. Artificial bone designs must be biocompatible, have osteoconductivity, and last for long periods of time inside a patient in order to be a viable solution compared to autologous and allogeneic bone implants. Artificial grafts maintain comparable compressive strength, but occasionally lack similarity to human bone in response to lateral or frictional forces. In particular, the topographyof artificial bone is inaccurate compared to its natural counterpart. In Grant et al., artificial bone grafts produced by fused deposition had on average a 20% lower coefficient
