| Popis: | Background and importance The standard clinical technique for repairing peripheral nerve gaps is the use of autologous sensory nerve grafts. The present study tested whether a collagen tube filled with autologous platelet-rich fibrin could induce sensory and motor recovery across a 12-cm nerve gap repaired 3.25 years post trauma, and reduce or eliminate neuropathic pain. Clinical presentation Two years postrepair, good ring and small finger motor function had developed that could generate 1 kg of force, and topographically correct 2-point discrimination and sensitivity to vibration in the small and ring finger and proximal but not distal wrist had developed. The patient's excruciating neuropathic pain was reduced to tolerable, and he avoided the indicated extremity amputation. The 12-cm-long nerve gap was bridged with a collagen tube filled with autologous platelet-rich fibrin. Conclusion We demonstrate that a conduit filled with platelet-rich fibrin can induce limited, but appropriate, sensory and motor recovery across a 12-cm nerve gap repaired 3.25 years post trauma, without sacrificing a sensory nerve, can reduce existing excruciating neuropathic pain to tolerable, and allow avoidance of an indicated upper-extremity amputation. We believe the technique can be improved to induce more extensive and reliable neurological recovery. |
