Dorsal Metacarpal Artery Flap And Abdominal Skin Flap To Repair The Dorsal Skin Defect Analysis Of Clinical Efficacy

Prone to dorsal skin and soft tissue and tendon defect of finger injury, clinicaltreatment is a bit trickier,and requires the use of more skin flap, dorsal metacarpal area,similar in color、quality、feel, repair dorsal skin defects ideal for the District fingerinjury, this article will repair back two flap of skin defects do a comparison ofexposition.Objective: To evaluate the palm dorsal artery island flap and abdominal flap repairthe finger dorsal skin and soft tissue defects clinical efficacy, the best surgical programto explore the clinical treatment of dorsal defects.Methods: This paper collected in the period from March2011to October2012,Dalian Central Hospital Hand Surgery admitted to the dorsal skin defects in40patientswith46fingers.Male patients29cases,11cases of female patients，aged18to56yearsold, an average of38.3years. According to the number of hospitalized were randomlydivided into two groups,the observation group：this group includes20cases of24fingers, the clinical application of the dorsal metacarpal artery island flap fortreatment;control group：there were20cases in this group22, treatment of clinicalapplication of abdominal skin flap method.In preparation for the two groups of patientswith preoperative and postoperative treatment were the same,postoperative functionalexercise timing began suffering means,the timing begins after suffering refers tofunctional training required to conduct regular follow-up, follow-up period of6to12months,a score by the sum of the scores of each to an objective evaluation of the clinicaleffect of the flap.(Only assessed by the District)Results：All flaps survived and the patients were followed up for6to12months,an average of8.6months, satisfied with the shape of the flap of the observation group,the flap is not bloated, good skin texture and elasticity, abrasion, the two-pointdiscrimination was5~7mm. For the area without obvious complications, PIP and MP activities in the normal skin flap area, the excellent and good rate was91.6%.Controlgroup repaired flap slightly bloated appearance, soft texture, flaps point discriminationfor10~13mm excellent rate of71.9%. Between the two groups (for example, number,gender, average age, etc.) the difference was not statistically significant (P>0.05),twosets of flaps comparable flaps developed more credible, the two groups of patients Theoperation time was no significant difference (P>0.05), two flap surgery time isbasically the same. Postoperative hospital stay, hospital costs difference was statisticallysignificant (P <0.01), the observation group, fewer hospital days, total cost ofhospitalization was significantly lower than the control group after6months follow-up,according to one by one comparison,10observation index concluded,concluded, theobservation group and control group of patients with hand function after significantdifference was statistically significant (P <0.05), after the observation group appearance,function, feel, etc. than the control group.Conclusion: Dorsal metacarpal artery island flap is an effective treatment fordorsal skin tissue defects,flap and the recipient site closer flap soft, beautiful appearance,by area high similarity, clinical anatomy studies have proved that the back of the handside of the dorsal metacarpal artery position is relatively constant, less clinicalvariability, flap blood supply (dorsal metacarpal artery8-12skin vessel), simpleoperation, high survival rate, back with tissue defect in the finger skin and tendon bonea feasible transfer to repair when necessary, and the operation is finished in one time,safe and reliable treatment effect, low cost, less damage to the donor,it is worthy ofclinical promote in clinical.but in some special conditions (Dorsal injury combined withdorsal metacarpal injury), abdominal skin flap is a good choice.
