Observation on the clinical efficacy of personalized design of free skin flap for precise repair of hand and wrist thermal compression wounds
Objective To explore the clinical efficacy of personalized design of free skin flaps for precise repair of hand and wrist thermal compression injuries.Methods From January 2013 to November 2021,32 patient with hand and wrist thermal compression injuries were treated.Based on the location,degree,and size of the wound,combined with the different needs of patients,personalized design of free skin flaps was applied to accurately repair 15 cases of simple finger wounds,3 cases of simple palm wounds,3 cases of simple wrist wounds,4 cases of palm combined finger wounds,3 cases of palm combined wrist wounds,and 4 cases of palmar combined finger wounds,3 cases of palmar combined wrist wounds,and 4 cases of palm combined finger and wrist wounds.The incision area of the skin flap was 2.0 cm × 1.5 cm to 30.0 cm x 8.0 cm.The donor area of the skin flap was directly sutured or skin graft,and surgery was performed within 1 to 3 weeks after the injury.Results After surgery,all 55 skin flaps from 32 patients in this group survived and were follow-up for a period of 6 months to 6 years,with an average of 14 months.The skin flap had a rosy color,a soft texture,and a non-bulky appearance(21 skin flaps were thinned).The limb function was well restored.The temperature,pain,and tactile sensation of the skin flap recovered,with a two-point discrimination of 5 to 11 mm and an average of 8 mm.The skin flaps without reconstructed sensation all restored protective sensation.Conclusion Based on the location,severity,and size of the thermal compression injury,personalized design of free skin flaps can accurately repair hand and wrist wounds,resulting in more targeted treatment and satisfactory results.
