[Effectiveness of dorsal perforator flap of cross-finger proper digital artery in treatment of high-pressure injection injuries of the finger].

Objective: To investigate the effectiveness of dorsal perforator flap of cross-finger proper digital artery in the treatment of finger soft tissue defect caused by high-pressure injection injury.

Methods: Between July 2011 and June 2020, 14 cases of finger soft tissue defect caused by high-pressure injection injury were repaired with dorsal perforator flap of cross-finger proper digital artery. All patients were male, with a mean age of 36 years (range, 22-56 years).

Flow-through Dorsoulnar Perforator Flap Repair of Soft-Tissue Defect of the Finger with Segmental Digital Arterial Defect.

The aim of this study was to investigate the feasibility of transferring the free flow-through dorsoulnar perforator flap to reconstruct severely injured fingers. From January 2015 to March 2019, 16 patients, 16 thumb or fingers volar partial defects concomitant with segmental digital arterial defects, were included in this study. The flow-through dorsoulnar perforator flaps were used to repair the finger wounds and reconstruct digit arteries.

[Effectiveness of combined tissue transplantation to repair serially damaged injuries on radial side of hand].

Objective: To investigate the effectiveness of combined tissue transplantation for repair of serially damaged injuries on radial side of hand and function reconstruction.

Methods: Between May 2013 and May 2017, 34 cases of serially damaged injuries on radial side of hand were treated. There were 29 males and 5 females; aged 17-54 years, with an average of 32.
