Artificial dermal repair for larger finger pulp defects: Satisfactory coverage with limitations in sensation and inevitable scar formation.

ABSTRACT

BACKGROUND: This prospective study aimed to evaluate the outcomes of the use of dermal templates for lengthy volar soft tissue defects (1.5-4 cm) in the fingers. METHODS: The volar soft tissue defects of 15 patients (19 fingers) were treated with Lando dermal template coverage between June 2022 and November 2022. We evaluated sensory recovery, scar formation, and overall appearance of the repair site at an average of 13 months (range, 12-17 months) of follow-up. RESULTS: The defect healed in all cases. We found an average static 2-point discrimination of 7 mm (range 4 to 14 mm). Scar formation was evident in all cases. The repair did not restore the bulkiness of the volar finger, especially in the finger with the bony exposure. Nail deformities and joint contracture were observed in some cases. CONCLUSION: Dermal template repair does not restore normal sensation and inevitably leads to scar formation when the defect is longer (>1.5 cm). Bulkiness of the volar finger is not restored in most patients, especially when there was bone or tendon exposure in the initial wound site.
