Internal obturator muscle it surrounds the greater part of the obturator foramen, being attached to the inferior pubic ramus and ischium, and at the side to the inner surface of the hip bone below and behind the pelvic brim, reaching from the upper part of the greater sciatic foramen above and behind to the obturator foramen below and in front. It also arises from the pelvic surface of the obturator membrane except in the posterior part, from the tendinous arch which completes the canal for the passage of the obturator vessels and nerve, and to a slight extent from the obturator fascia, which
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
