Treatment of complex soft-tissue defects at the metacarpophalangeal joint of the thumb using the bilobed second dorsal metacarpal artery-based island flap.

Background: The purpose of this study is to report on reconstruction of complex soft-tissue defects around the metacarpophalangeal joint of the thumb using a bilobed second dorsal metacarpal artery-based island flap taken from the dorsum of the proximal phalanges of the index and long fingers.

Methods: From March of 2007 to October of 2009, the bilobed second dorsal metacarpal artery-based island flap was transferred in 13 patients. There were two defects on the metacarpophalangeal joint of the thumb.

Temporary ex vivo posterior tibial artery bypass for iliofemoral artery injury.

Background: The objective of this study is to report a temporary, ex vivo, distal extremity revascularization technique providing distal perfusion and allowing for a staged repair of complex iliofemoral injury. In addition, the objective of this report is to provide outcome data after this novel procedure including mortality, limb salvage, and quality of limb assessment.

Methods: From February 1993 to December 2005, temporary ex vivo posterior tibial artery revascularization from the uninjured (donor) to the injured extremity was performed in 14 patients.
