Posterior compartment of the forearm Posterior compartment of the forearm The posterior compartment of the forearm (or extensor compartment) contains twelve muscles which are chiefly responsible for extension of the wrist and digits, and supination of the forearm. It is separated from the anterior compartment by the interosseous membrane between the radius and ulna. There are generally twelve muscles in the posterior compartment of the forearm, which can be further divided into a superficial, intermediate, and deep layer. Most of the muscles in the superficial and the intermediate layers share a common origin which is the outer part of the elbow, the lateral epicondyle of
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
