Impact of single versus dual arterial supply on perfusion and function in finger replantation after complex hand injuries.

Finger amputations following complex hand injuries (CHI) pose a significant challenge in hand surgery due to severe tissue trauma and neurovascular damage, necessitating precise arterial repair. While restoring arterial perfusion is critical, it remains unclear whether reconstructing both proper palmar digital arteries is required for optimal outcomes. This study evaluates whether restoring one or both arteries in finger replantation after complex injuries impacts perfusion and overall outcomes.

Shifting trends in outpatient hand trauma care: a 16-year analysis at a major center in northern Germany.

Background: Hand injuries are a leading cause of emergency department visits. Recent trends in hand trauma management reflect a shift toward outpatient care, driven by factors such as a shortage of skilled personnel or increasing cost pressures. This study analyzed these trends to propose updated management strategies for hand injuries.

Suboxides and subselenides: intermediate reaction products to form GaO, GaSe, InO, InSe, SnO, and SnSe during molecular-beam epitaxy.

The molecular-beam epitaxial (MBE) growth of III-O and IV-O materials (, GaO, InO, and SnO) is known to be reaction-limited by complex 2-step kinetics and the desorption of volatile suboxides (, GaO, InO, SnO). We find that the different surface reactivities of suboxides and respective elements (, Ga, In, Sn) with active oxygen define the film-growth-windows (FGWs) and suboxide-formation-windows (SFWs) of III-O and IV-O materials, respectively. To generalize, we provide elementary reaction pathways and respective Gibbs energies to form binary III-O, III-Se, IV-O, and IV-Se ground-states as well as their subcompounds during their MBE growth.
