https://www.selleckchem.com/products/ca-170.html Large bone defects or complex pseudarthrosis represent an interdisciplinary challenge. Established surgical procedures include autogenous cancellous bone graft, the Masquelet technique or bone transfer via segment transport as well as free microvascular bone transplantation. However, the successful use of all these techniques requires a specialized center with great interdisciplinary expertise. In the following case series we describe the technique of free fibula transplantation and additional allograft. In both cases a good functional result with full mechanical strength of the affected extremity and satisfactory patient comfort has been achieved. In the second case, implant failure with the necessity of revision endoprosthetics occurred during the procedure.Background The abdomen remains the most preferable donor site for autologous breast reconstruction. Many patients in this population will have had prior abdominal surgery, which is the chief risk factor for having a ventral hernia. While prior studies have examined the impact of prior abdominal surgery on breast reconstruction, limited data exist on the management of patients with a preexisting ventral hernia. The objective of this study was to investigate outcomes of performing ventral hernia repair concurrent with abdominally based microsurgical breast reconstruction. Methods A 5-year retrospective review of patients undergoing abdominally based microsurgical breast reconstruction was performed. The experimental group consisted of patients with a preexisting ventral hernia that was repaired at the time of breast reconstruction, and was compared with a historical cohort of patients without preexisting hernias. Results There were a total of 18 and 225 patients in the experimental and control groups, respectively. There was a higher incidence of prior abdominal surgery in the experimental group (p = 0.0008), but no other differences. Mean follow-up was 20.5 ± 5.2
