The Pubic Bone Graft: Rationale and Technique in a Cleft Patient

W. Jason Martin, MD

Historically, the ilium has been the preferred harvest site for cancellous bone grafts. This procedure, however, has well documented morbidity, including lateral femoral cutaneous nerve injury with potential for painful neuroma, significant post-operative pain, unsightly scar formation and iliac crest contour deformities. To avoid these complications, we propose an alternative harvest site for cancellous bone, the pubic tubercle and the superior ramus of the pubis. Utilizing the experience from fresh cadaver dissections, the procedure includes a 3cm transverse midline incision superior to the pubic tubercle, minimal soft tissue dissection to the tubercle, a pubic cortical window and procurement of the desired volume of cancellous bone. This procedure has now been successfully completed on 12 alveolar cleft patients. Post-operative clinical evaluations revealed no wound complications and minimal pain. An adequate volume of cancellous bone was easily obtained and the scar is hidden in the hair bearing area of the pubis. This technique is safe, simple and avoids the morbidity associated with iliac grafts.
