    Perforator artery repair in revascularization of extremity degloving injuries
    Kabakas, F; Özçelik, IB; Mersa, B; Dagdelen, D; Aksakal, IA; Özalp, T
    Introduction: This article aims to expand the microsurgical treatment options for extremity degloving injuries with perforator artery repairs of the specific degloved angiosomes in upper and lower extremity. Methods: Fourteen perforator arteries were repaired in seven patients. Four of them had circumferential degloving and 3 of them have non circumferential degloving injury. All had repair of the perforator arteries of the specific degloved segments. Four patients had additional vein repairs but none of the patients had AV shunts. Results: All perforators provided adequate arterial supply to their specific angiosomes with some necrotic areas in neighboring angiosomes. Conclusions: Perforator artery repair within the degloved tissues provides a direct arterial supply successfully even if one could not find an intact venous plexus. (C) 2019 Elsevier Ltd.

    A novel nerve transfer: The first palmar interosseous motor branch of the ulnar nerve to the recurrent motor branch of the median nerve
    Ozcelik, IB; Yildiran, G; Mersa, B; Sutcu, M; Celik, ZE; Ozalp, T
    Introduction: The recovery of recurrent motor branch of the median nerve might be delayed in high level median nerve injuries due to the long reinnervation distance. The aim of this study is to define a novel nerve transfer to restore the opposition and pinch. Methods: Two fresh frozen hand cadavers were used for the study. The motor branch of the first palmar interosseous muscle of the ulnar nerve was identified and dissected. Thenar branch of the median nerve was dissected from its insertion site. The motor branch of the first palmar interosseous muscle of the ulnar nerve was transferred to the thenar motor branch of the median nerve. Axon counts were examined histopathologically. Clinically this nerve transfer was performed for two female patients with a high-level median nerve injury. Mehta opposition scores were 21 and 20, respectively and the results were satisfactory six months after the surgery. Discussion: Although exploration and repair are recommended as the first treatment for median nerve injuries, the waiting time until the motor branch is reinnervated is critical in high level lesions. Nerve transfers become very important for fast recovery. Conclusions: This new nerve transfer proposal may be an important step in nerve transfer surgery. (C) 2020 Elsevier Ltd. All rights reserved.
