The goal of this study was to test the efficacy of local analgesic (lidocaine) loaded hemostatic putty in reducing donor site pain following the harvest of pelvic bone grafts. In 14 patients undergoing harvest of a pelvic bone graft during foot surgery, the bone defect at the pelvis was either filled with a lidocaine loaded hemostatic putty (Orthostat-L) or the same putty without lidocaine (Orthostat, currently marketed as Hemabsorb). Postoperatively, foot pain was eliminated with a peripheral nerve block, while pelvis pain was quantified with two commonly used pain rating scales (VAS and Wong Baker). Blood samples were collected at regular time intervals to measure lidocaine levels. Patients which received the lidocaine loaded putty experienced significantly less pain during the first 12 hours after surgery as compared to those patients who received the lidocaine deficient putty. Blood lidocaine levels always stayed below the toxic threshold.
