Postamputation pain affects a large number of individuals living with major limb loss. Regenerative peripheral nerve interfaces are constructs composed of a transected peripheral nerve implanted into an autologous free muscle graft. The authors have previously shown that regenerative peripheral nerve interfaces can be used to treat symptomatic end neuromas that develop after major limb amputation. In this study, they investigated the potential of prophylactic interfaces to prevent the formation of symptomatic neuromas and mitigate phantom limb pain.
Prophylactic regenerative peripheral nerve interfaces in major limb amputees resulted in a lower incidence of both symptomatic neuromas and phantom limb pain compared with control patients undergoing amputation without regenerative peripheral nerve interfaces, suggesting that prevention of peripheral neuromas following amputation may diminish the central pain mechanisms that lead to phantom limb pain.
