Here, we report a case of reconstruction of the right midfoot with the trauma-related osteomyelitis using a free chimeric scapula and LD muscle flap in a 59-year-old
woman with diabetes mellitus. After radical debridement and sequestrectomy, a 7 × 3 cm2 wound with a 5 × 3 cm2 bony defect was reconstructed with the chimeric scapula and LD muscle flap. The postoperative course was Ruxolitinib uneventful. The bony union was achieved 6 months after surgery. In 14 months follow-up, no clinical complications including a new ulcer or stress fracture were noted. At the end of follow-up, the gait analysis showed an unbalanced stress distribution on the right foot and a valgus gait. We suggest that this chimeric scapula and LD muscle flap may be an alternative option for midfoot reconstruction. © 2012 Wiley Periodicals, Inc. Microsurgery, 2012. “
“Whether post-traumatic regeneration can eventually result in rat peripheral nerve fibers regaining their pretrauma size is still an open question. While it has been shown that, after a sufficient duration in post-traumatic time, the number of regenerated rat peripheral nerve fibers can return to
pretrauma numbers and the animal can regain normal prelesion function, no information regarding long-term changes in the size parameters of PF-02341066 datasheet the regenerated nerve fibers is available. To fill this gap, we have investigated the post-traumatic changes in myelinated axon and nerve fiber diameter, myelin thickness, and g-ratio (the ratio of the inner axonal diameter to the fiber diameter) at three different time points following nerve injury: week-6, week-8, and week-24. A standardized nerve crush injury of the rat median nerve obtained using a nonserrated clamp was used for this study. The results showed that, consistent with previous studies, fiber number returned to normal values at week-24, but both axon and fiber diameter and myelin thickness oxyclozanide were still
significantly lower at week-24 than prelesion, and the g-ratio, which remained unchanged during the regeneration process, was significantly reduced at week-24 in comparison to the prelesion value. On the basis of these results, the hypothesis that regenerated rat peripheral nerve fibers are able to return spontaneously to their normal pretrauma state, provided there is a sufficiently long recovery time postaxonotmesis, is not supported. © 2012 Wiley Periodicals, Inc.

“The biology behind vascularized bone allotransplantation remains largely unknown. We aim to study cell traffic between donor and recipient following bone auto-, and allografting. Vascularized femoral transplantation was performed with arteriovenous bundle implantation and short-term immunosuppression.
