Use of partial nail carried by great toe fibular flap for repairing the defect of fingertip soft tissue and nail bed: 12 cases report / 中华显微外科杂志

Objective To investigate the method and clinical outcome of partial nail carried by great toe fibular flap for repairing the defect of fingertip soft tissue and nail bed.Methods From June,2016 to October,2017,12 cases suffered the defect of fingertip soft tissue and nail bed.The injury fingers included 5 index fingers,6 mindle fingers and 1 ring finger.All cases were complicated with nail bed defect of different degrees.The nail matrix was intact.The area of fingertip defect ranged from 1.0 cm×1.0 cm to 1.5 cm×2.5 cm.The area of nail bed defect ranged from 0.2 cm×0.8 cm to 0.5 cm×1.5 cm.Great toe fibular flap combine with partial nail was harvested.Donor site was directly sutured or skin grafting according to the size.The regular preoperative followed-up was performed.Results All flaps survived with donor sites healing good.The average followed-up time was 7 (ranging from 2 to 10) months,and cosmetically acceptable results were achieved for all patients.The mean static 2-PD in the flaps was 7.5 (range,6.0 to 8.0) mm.No obvious deformity of the great toe nail.Conclusion Findings proved that using partial nail carried by great toe fibular flap is a beneficial microsurgical alternative for reconstructing defect of fingertip soft tissue and nail bed.

Transplantation of slice nail bed flap of great toe with vascular anastomosisin repairing nail bed and soft tissue defect of fingers / 中华显微外科杂志

Objective To discuss the clinical effect of transplantation of slice nail bed flap of great toe with vascular anastomosis in repair of partial nail-bed and soft tissue defect at fingers.Methods From January,2015 to March,2018,16 cases (16 fingers) of partial nail-bed defect at fingers were repaired with transplantation of slice nail bed flap of great toe with vascular anastomosis.All cases were combined with palmar soft tissue defect at distal segment fingers.The area of nail bed defects were from 0.8 cr×0.5 cm to 1.2 cm×1.0 cm.The area of soft tissue defects were from 1.2 cm×1.0 cm to 2.5 cm×1.5 cm.The average time from injury to operation was 3.6 hours after injuries (ranging from 1 hour to 8 hours).The area of slice nail bed flap incised during operation were from 2.5 cm×1.2 cm to 3.2 cm×1.8 cm,and the donor site was sutured directly.All patients were followed-up regularly for nail appearance,function and donor healing.Among them,11 cases were followed-up by clinic,4 cases by WeChat,and telephone follow-up was performed in 1 case.Results The nail-bed flap after transplantation survived successfully.The followed-up time were from 6 to 18 months,the average time was 9 months.Longitudinal spine and rough appearance occurred in 1 case.Others were flat,smooth,complete attachment of nail body and nail bed.The flaps had good appearance,texture and elasticity at 6 months after surgery,and two-point discrimination was 6-12 mm(average,8 mm).The toenails at donor sites grew well.No walk-associated pain after long-term following-up.Six months after surgery,according to standard for efficacy evaluation of nail regeneration,12 cases were excellent,3 cases were good and 1 case was acceptable.Conclusion Transplantation of slice nail bed flap of great toe with vascular anastomosis in repair of partial nail-bed and soft tissue defect at fingers is one of the effective methods for repairing nail-bed defect at fingers.

Decorative repair of nail-bed defect at finger by partial nail-bed flap at second toe with blood-vessel anastomosed / 中华显微外科杂志

Objective To discuss the clinical effect of partial nail-bed flap at second toe with blood-vessel anastomosed in repair of different types of nail-bed defects at finger.Methods From July,2010 to July,2015,25 cases of partial nail-bed flap at second toe with blood-vessel anastomosed were treated,including 14 males and 11 females,with an age range from 18 to 45 years old (average 25 years old).Eleven cases at index finger,6 cases at middle finger,5 cases at ring finger and 3 cases at little finger.According to the classification of nail bed defect site,9 cases at lateral,5 cases at nail root and 11 cases at distal.All cases were combined skin and soft tissue defect.The area of defects were from 1.1 cm × 2.0 cm to 2.5 cm × 3.2 cm.The time from injury to admission were from 1 hour and 12 minutes to 3 hours and 12 minutes,the average time was 2.1 hours.The area of incised nail flap during operation were from 1.2 cm × 2.2 cm to 2.6 cm × 3.5 cm.The donor site was sutured directly or repaired with free skin graft.The toe length in all cases were retained.The nail shape,nail gloss,fine function of finger such as pinch,grip,grasp and restoration of the donor toes were compared in the follow-up.All patients were followed-up at regllar intervals.Results The nail-bed flap after transplantation and skin graft at donor site survived successfully,and primary healing of the wounds occured in all cases.The follow-up time were from 6 to 26 months(average 9 months).Longitudinal spine or transverse groove occurred in 3 cases at the nail-bed boundary between toe and finger,nail thickened and distal tilted occurred in 1 case,flat,smooth,no deformity nail and glossy deck occurred in others.The flap had good appearance,texture and elasticity.Two-point discrimination was 5-9 mm,averageal of 6 mm.The donor toe had no shortening and no pain after long-term following.According to effectiveness standard for fingernail regeneration:19 cases were excellent and 6 cases were good.Conclusion Partial nail-bed flap at second toe wih bloodvessel anastomosed in repairing nail-bed defects at finger,nail appearance is realistic and function recovered well postoperatively.
