Comparison of clinical efficacy of two types of mini-flaps in repairing finger-tip soft tissue defects
Objective To investigate the clinical efficacy of two types of mini-flaps in repairing the degree Ⅱ finger-tip soft tissue defects.Methods From January 2018 to June 2021,based on the nature and severity of the injury,the type of injury,and the patient's wishes,we used a composite tissue flap from the fibular and dorsal side of the toe to reconstruct 20 patients with degree Ⅱ finger defects(Group A),and another 20 patients were repaired using a free radial artery wrist transverse perforator flap(Group B).The survival of the skin flap after surgery was followed up and observed,and the two-point discrimination(2PD)testing on the skin flap was performed.The recovery of sensory function between the two groups of patients was compared.Results All 40 flaps survived after surgery,and the follow-up time was 18 to 36 months,with an average of(20.05±10.36)months.The texture of the flaps was good,and their appearance and function were satisfactory.At postoperative follow-up of 6,12,and 18 months,there were statistically significant differences between the 2PD of the A and B groups of skin flaps and the healthy side of the normal finger(P＜0.05).Conclusion Two types of mini-flaps are ideal for repairing finger-tip soft tissue defects,with high survival rates and good sensory function recovery.The reasonable selection and application are necessary.
