Implant systems and methods treatment of a joint include a distal portion, a middle portion, and a proximal portion. The distal portion may include a thread having a first thread minor, a first thread major, and a first pitch. The distal portion also may have a reverse cut, helical fenestration formed through the thread. The middle portion may be devoid of threads and may include a porous outer surface structure to promote bony integration, the porous outer surface structure having a leading end and a trailing end, with the leading end having a diameter larger than the first thread minor. The proximal portion may include a proximal thread having a second thread minor, a second thread major, and a second pitch. The second thread minor may be substantially the same width as the trailing end of the middle portion.
