An assessment by the BlueCross BlueShield Association Technology Evaluation Center (BCBSA, 2014) stated: "The choice of bone material for interbody fusion in [anterior cervical discectomy and fusion] ACDF has important clinical implications. Allograft bone has several drawbacks, including a minute (albeit unproven) risk of infectious disease transmission; possible immunological reaction to the allograft; and possible limited commercial availability of appropriate graft material. In contrast, the use of autograft bone in ACDF has potentially substantial morbidities at the harvest site, generally the iliac crest. These include moderate-to-severe, sometimes prolonged pain; deep infection; adjacent nerve and artery damage; and increased risk of stress fracture. Although there may be slight differences between autograft and allograft sources in the postoperative rate of union, clinical studies have demonstrated similar rates of postoperative fusion (90%–100%) and satisfactory outcomes for single-level, anterior-plated ACDF using either bone source. Thus, the choice of graft material involves a trade-off between the risks specific to autograft harvest versus those specific to use of allograft material."
The smart prepper understands well that going it alone is not an option, at least not for the long term. Thus, we are required to build relationships with those who live near us. If we cannot find enough like-minded souls in our immediate vicinity, then we must relocate to a place where this process is more viable (at least, if we want to survive). Staying put, wrapped in a web of tract homes or city dwellings filled with dangerously unaware and unprepared people is not an intelligent post collapse strategy. Retreat planning without proper group support and indigenous support is not only a logistical nightmare but a surefire avenue to discomfort of the terminal variety.
