Clinical study on vacuum assisted closure combined with multiple flaps in the treatment of severe hand trauma

Objectives: To investigate the effect and clinical value of the application of vacuum assisted closure (VAC) combined with multiple flaps in the treatment of severe hand trauma.

Methods: A total of 100 patients with severe hand trauma admitted to Harrison International Peace Hospital from September 2015 to September 2020 were selected and randomly divided into two groups according to the randomized block method: the single flap repair group and the combined repair group, with 50 patients in each group. Patients in the single flap repair group underwent flap repair according to their condition, while those in the combined repair group were treated with VAC prior to flap repair. The range of motion and hand sensation scores were compared between the two groups, and their levels of interleukin-8 (IL-8), tumor necrosis factor (TNF) and lipopolysaccharide (LPS) were tested by enzyme-linked immunosorbent assay (ELIS). Moreover, the flap survival rate and the incidence of adverse events were recorded and compared between the two groups.

Results: Compared with the single flap repair group, the combined repair group had higher range of motion and hand sensation score (p<0.05), lower levels of IL-8, TNF and LPS (p<0.05), higher flap survival rate (p<0.05), and lower incidence of adverse events (p<0.05).

Conclusion: VAC combined with multiple flaps boasts significant trauma repair effect and preferable clinical application value in the treatment of patients with severe hand trauma, which is principally reflected in significantly improving the hand function of patients and remarkably alleviating the inflammatory response of patients.
