ABSTRACT

Objective To explore the clinical curative effect for wound surface of hand heatcompression injury treated by improved posrerior interosseous artery reversed island flap.Methods Between January,2010 and September,2015,20 patients were treated for wound surface of hand heatcompression injury.Of 20 cases,there were 16 males and 4 females,aged 18-45 years (mean,32 years);and the left hand was involved in 9 cases and the right hand in 11 cases.Two-stage repair was performed in 20 cases after emergency admission.The locations of heatcompression injury were dorsal hands in 12 cases,first webs in 6 cases,and dorsal thumb in 2 cases.The wound area of hand heatcompression injury were 4.0 cm×5.0 cm-6.0 cm×8.0 cm,which were all repaired by improved interosseous dorsal artery retrograde island flap whose area were 3.5 cm ×4.5 cm-7.0 cm×8.0 cm.One week after operation,fingers and thumb-index web began to promote rehabilitation functional training in the protection of orthosis.All patients were followed-up at regular intervals.Results All postoperative flap and the grafted skin at donor sites survived.Twenty patients were followed-up for 3-12 months (mean,6.5 months).The flaps had satisfactory appearance and soft texture.The thumb web widing and flexion and extension of the fingers were fine.According to Trial Standard Evaluation of the Upper-Limb Part Function of the Hand Surgery Association of the Chinese Medical Association,the results were excellent in 12 cases,good in 6 cases,and fair in 2 cases at 3 months after operation.Conclusion To repair wound surface of hand heatcompression injury by improved posterior interosseous artery reversed island flap is a fairly ideal operative approach.The type of operations is simple in operation,has high survival rate of postoperative skin flap.
