title: Bone Anchor Fixation in Abdominal Wall Reconstruction: A Useful Adjunct in Suprapubic and Para-iliac Hernia Repair.
abstract: Suprapubic hernias, parailiac or flank hernias, and lumbar hernias are difficult to repair and are associated with high-recurrence rates owing to difficulty in obtaining substantive overlap and especially mesh fixation due to bone being a margin of the hernia. Orthopedic suture anchors used for ligament reconstruction have been used to attach prosthetic material to bony surfaces and can be used in the repair of these hernias where suture fixation was impossible. A prospective, single institution study of ventral hernia repairs involving bone anchor mesh fixation was performed. Demographics, operative details, and outcomes data were collected. Twenty patients were identified, with a mean age 53 (range: 35-70 years) and mean body mass index 28.4 kg/m(2) (range 21-38). Ten lumbar, seven suprapubic, and three parailiac hernias were studied. The majority were recurrent hernias (n = 13), with one to seven previously failed repairs. The mean hernia defect size was very large (270 cm(2); range: 56-832 cm(2)) with average mesh size of 1090 cm(2) (range 224-3640 cm(2)). Both Mitek GII (Depuy, Raynham, MA) and JuggerKnot 2.9-mm (Biomet, Biomedical Instruments, Warsaw, IN) anchors were used, with an average of four anchors/case (range: 1-16). Mean operative time was 218 minutes (120-495). There were three minor complications, no operative mortality, and no recurrences during an average follow-up of 24 months. Pelvic bone anchors permit mesh fixation in high-recurrence areas not amenable to traditional suture fixation. The ability to safely and effectively use bone anchor fixation is an essential tool in complex open ventral hernia repair.
