Abstract:
Objective To explore the clinical application effects of artificial dermis in the repair of traumatic finger skin defects with bone exposure.Methods From January 2022 to January 2024,10 patients with fingertip skin defects and bone exposure,totaling 10 fingers,were treated.The defect areas ranged from 0.5 cm × 1.0 cm to 1.0 cm × 1.5 cm.After debridement,the wounds were covered with artificial dermis,and regular dressing changes were performed postoperatively.The artificial dermis was removed 3-4 weeks post-surgery.The wound healing,skin appearance,and sensory recovery of the fingertip were evaluated.Results All 10 fingertip wounds healed successfully,with a healing time of 3 to 4 weeks.Patients were followed up for more than 3 months,and the wound healing was satisfactory.The finger pads appeared full,the skin was smooth and flat with no obvious scarring,and the texture was soft.Skin sensory ability recovered well,with no pain or hypersensitivity,and the two-point discrimination ability reached 3 to 8 mum.According to the upper limb function evaluation standards set by the Hand Surgery Society of the Chinese Medical Association,the sensory recovery of all 10 fingertips achieved an S3+level,with a good to excellent rate of 100％.Conclusion The primary repair of fingertip skin defects with bone exposure using artificial dermis resulted in no donor site damage.The surgical procedure is safe and simple,and the appearance and sensory function of the fingers have recovered well,demonstrating reliable efficacy.
