Usage of Dermal Substitutes for Hand Coverage and Reconstruction.

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.
