The success of the procedure is related to decompression of the femoral head, excision of the necrotic bone, and addition of cancellous bone graft with osteoinductive and osteoconductive properties, which augments revascularization and neoosteogenesis of the femoral head. Free vascularized fibula graft, especially in younger

patients, is a salvaging procedure of the necrotic femoral head in early precollapse stages. In postcollapse osteonecrosis, the procedure appears to delay the need for total hip arthroplasty in the majority of patients. The purpose of this review article is to update knowledge about treatment strategies in femoral head Ponatinib ic50 osteonecrosis and to compare free vascularized fibula grafting to traditional and new treatment modalities. © 2010 Wiley-Liss, Inc.

“Some sensation to the breast returns after breast reconstruction, but recovery is variable and unpredictable. We primarily sought to assess the impact of different types of breast reconstruction selleckchem [deep inferior epigastric artery perforator (DIEP) flaps versus implants] and radiation therapy on the return of sensation. Thirty-seven patients who had unilateral or bilateral breast reconstruction via a DIEP flap or implant-based reconstruction, with or without radiation therapy

(minimum follow-up, 18 months; range, 18–61 months) were studied. Of the 74 breasts, 27 had DIEP flaps, 29 had implants, and 18 were nonreconstructed. Eleven breasts with implants and 10 with DIEP flaps had had prereconstruction radiation therapy. The primary outcome was mean patient-perceived static

and moving cutaneous pressure threshold in nine areas. We used univariate and multivariate analyses to assess what independent factors affected the return of sensation (significance, P < 0.05). Implants provided better static (P = 0.071) and moving sensation (P = 0.041) than did DIEP flaps. However, among irradiated breasts, skin over DIEP flaps had significantly better sensation than did that over implants (static, P = 0.019; moving, P = 0.028). Implant reconstructions with irradiated skin had significantly worse static (P = 0.002) and moving sensation (P = 0.014) than did nonirradiated implant reconstructions. Without irradiation, skin overlying implants is PIK3C2G associated with better sensation recovery than DIEP flap skin. However, with irradiation, DIEP flap skin had better sensation recovery than did skin over implants. Neurotization trended toward improvement in sensation in DIEP flaps. © 2013 Wiley Periodicals, Inc. Microsurgery 33:421–431, 2013. “
“We report a case of Fournier’s gangrene, where we used the greater omentum as a free flap for scrotal reconstruction and outline the advantages over previously described methods. The greater omentum was harvested using a standard open technique. The deep inferior epigastric vessels were passed through the inguinal canal into the scrotal area as recipient vessels.
