Usage of Dermal Substitutes for Hand Coverage and Reconstruction

Abstract

Abstract Background Hand coverage and reconstruction gives a challenge for plastic surgery. In this study we introduce a method for hand coverage and reconstruction by dermal substitutes which easy and simple to use. Objectives The aim of this study is to know the versatility of dermal substitutes in reconstruction & coverage of complex hand defects. Patients and Methods This was a cohort study conducted on 20 patients with hand tissue loss; to evaluate the versatility of dermal substitutes in reconstruction & coverage of complex hand defects. Patients attending El Helmeia armed forces hospital (plastic and reconstructive department) & Ain shams university hospital with follow up duration up to 6 months. All patients had clean wound & complex hand defects with exposed tendon and/or bone, Defects post trauma and after tumour excision and Post burn hypertrophic scars, keloid or contractures. Results We found that; the mean age of all patients was (23.5 ± 8.82) years. Regarding gender of the patients, the majority (80%) of patients were males; while (20%) were females. Regarding side of raw area; (55%) of patients had Rt-sided raw area, and (45%) had Lt-sided raw area. Regarding site of raw area; (20%) of patients had Finger-tip raw area, (20%) had Palm raw area, (10%) had Volar surface of little and ring raw area, (10%) had Volar surface of little finger raw area, (25%) had Dorsum raw area, (10%) had Dorsum of lateral 4 fingers raw area, while (5%) had Dorsum of middle finger raw area. Regarding Etiology of raw area; (70%) of raw areas caused by Trauma, (15%) caused after burn keloid removal, (10%) caused after burn contracture, and (5%) caused by donor site. Regarding Intervention data; (50%) of patients used Integra dermal substitute; and (50%) used Pelnac dermal substitute. Regarding follow up data; the average Time of removal was (3.65 ± 0.49) weeks, and the average Time for follow up was (3.25 ± 1.12) months. Comparative study between 20 hand tissue loss patients revealed; highly significant increase in Post-operative STSG satisfaction rate (70%); with highly significant statistical difference (p < 0.01), highly significant increase in Post-operative STSG good movement (80%); with highly significant statistical difference (p < 0.01). Conclusion The use of dermal substitutes cons gives an alternative reconstructive option for managing extended skin avulsion injuries of the upper extremity; it reduces postoperative immobilization, minimizes donor site morbidity and provides good functional and esthetic results in a single surgical procedure.
