Resorbable medical implants and related methods are disclosed for placement against bone and/or for filling a void such as a void between bones. The resorbable medical implants can be structured and configured as desired, for example, to conform to surfaces of adjacent bones and/or to conform to a desired bone shape for replacement otherwise. Short-term fixation of the resorbable medical implants can advantageously assist in promoting and allowing growth of new bone tissue into the implant as the implant gradually resorbs. The implant can comprise a material that is porous with microscopic and non-microscopic pores. In one aspect, the resorbable implant can be shaped and used as a trapezium bone replacement.
