Medial sural artery perforator free flap: legitimate use as a solution for the ipsilateral distal lower extremity defect.
The medial sural artery perforator (MSAP) flap captures the cutaneous territory of the medial calf, and can potentially be advantageous as a thin free flap, even in the most obese individual, for coverage of most foot and/or ankle defects where bulk is a liability. The anatomy is fairly constant, as usually at least one reasonably large perforator can always be found emanating from the medial head of the gastrocnemius muscle. As a microsurgical tissue transfer, a long vascular pedicle of large caliber is routinely possible which facilitates any requisite microanastomoses. ⋯ The study concluded the major disadvantage of the MSAP flap is the nonaesthetic scar left at the donor site which can be quite conspicuous, especially if a skin graft had to be used. Yet even this detriment can be acceptable for ipsilateral distal lower extremity defects where reconstruction of the defect itself may be cosmetically unappealing. This may be the best indication for the MSAP flap to be considered first as the free flap of choice.

Modified pathological classification of brachial plexus root injury and its MR imaging characteristics.
The authors described a modified pathological classification (PC) of brachial plexus injury (BPI) and its magnetic resonance (MR) imaging characteristics. The reliability and diagnostic accuracy of MR imaging for detecting nerve injury was discussed. Between 2006 and 2010, 86 patients with BPI were managed surgically in our department. ⋯ The main MR imaging characteristics of BPI included traumatic meningocele, displacement of spinal cord, the absence of nerve root, "Black line" sign, nerve root/trunk injury in continuity, and thickening and edema of nerve root. The accuracy of MR imaging for detecting C5, C6, C7, C8, and T1 nerve roots injury were 93.3, 95.2, 92.3, 84, and 74.4%, respectively. The modified PC provides a detailed description of nerve root injury in BPI, and MR imaging technique is a reliable method for detecting nerve root injury.
