The Research Of Repairing Class Ⅰ Degloving Injuries Of Fingers By Combining The Flaps Of The Second Toes

Objective: To explore the new surgical treatment and curative effect forclassⅠdegloving injuries of fingers．Methods:Basic research and clinical application were needed.The former includesexperiments of living body measurement and cadaveric model.The experiment of livingbody measurement:the skin beyond the middle section of50people’s middle fingers wasdivided into dorsal part and palmar part,according to both sides of the center line. Thelength, the proximal width and the distal width of them were measured. Also,that of thewrap around flap of one second toe and the tibial flap of another second toe weremeasured,and compared with each other. The experiment of cadaveric model:25cadaversmodel of classⅠdegloving injuries of fingers were made.Measuring the size of skin andwound partly. Flap coefficient was calculated. Designing and cutting the flap according toflap coefficient,and repairing model of classⅠdegloving injury of finger, observing therepairing effects. Clinical application of15fingers of15patients were followed up for6-24months.Results： The experiment of living body measurement pointed out that thecorresponding diameter size of the wrap around flap of one second toe and the tibial flap ofanother second toe was higher than that of skin of finger. The flap coefficient of the palmarpart was1.5,and that of the dorsal part was1.3after measured.The appearance of fingermodel was similar to normal finger after repaired.Flaps of clinical application were allsurvived, After6-24months of follow-up，the repaired fingers were similar to normalfingers with Good feeling, two-point discrimination was6to10mm. According to thefunctional evaluation standard，The functional results were encouraging in all patients(10excellent,4good，and1fair),with an excellent and good rate of93.3%. Donor sites of thetoes healed well without scarring, walking completely normal. Conclusions: Using wrap around flaps of the second toe and tibial flaps of theopposite second toe to repair class I degloving Injuries of fingers is an ideal method. Flapcoefficient was a simplified new tool for the clinical treatment of class I degloving injuryof finger.
