Objective:To explore the method and effect of aesthetic reconstruction of distal segment of finger with modified second toe nail flap while retains the full length of the second toe.Methods:From April 2018 to June 2020, 16 patients with degloving injury of distal segment of fingers were treated. The patients were 11 males and 5 females aged 18 to 45 years in an average of 29 years. All injuries were degloving injury of the distal segment of finger, including 5 index fingers, 7 middle fingers, 3 ring fingers and 1 little finger. The time from injury to operation was 0.5-3.0 hours, with an average of 1.5 hours. The second toe nail flap was used for the reconstruction. After the dorsal flap of the second toe was rotated to the plantar side of the foot, the donor site defect was repaired by a skin graft. The regular follow up reviews were carried out.Results:All 16 flaps survived except 1 flap had necrosis and underwent toe amputation of the distal segment of the second toe. All patients entered follow-up for 4-12 months, with an average of 5.7 months. The blood supply of all flaps was good. After the flaps having atrophied, they were equivalent to the diameter of the body of normal fingers with the TPD at 6.5(4-10) mm; All patients returned to work. According to the Evaluation Standard of Upper Limb Function of Chinese Hand Surgery Society, 13 cases were graded as excellent, 2 were good and 1 was fair.Conclusion:The techniques of modified second toe toenail flap in aesthetic reconstruction of the distal segment of a finger can effectively restore the length and aesthetic appearance of the affected finger, without sacrificing the donor toe. Clinical application of it should be promoted.
摘要
The aim of extremity reconstruction has focused on early wound coverage and functional recovery but rarely aesthetics. As the quality of life improves, however, the request for aesthetics has been growing. The authors has conducted retrospective reviews on the 86 cases that had extremity reconstruction using free flap, considering the characteristics of parts that had been assessed in primary operation between May 1996 and December 2010. Aesthetic grading was performed in four categories; color, texture, contour and marginal scar. Recipient sites were 42 hands, 19 feet, 14 lower extremities excluding feet and 10 upper extremities apart from the hand. Types of free flap were 16 latissimus dorsi free flaps, 13 anterolateral thigh free flaps, 12 dorsalis pedis free flaps, 8 transvers rectus abdominis free flaps, 7 gracillis free flaps, and 5 superficial temporal fascia free flaps. Total flap necrosis was seen in 8 cases(9.3%) and partial necrosis in 5 cases(5.8%). Secondary revision was done in 24 cases(27.9%) and the most common revision, debulking was done in 14 cases(16.3%). The authors has considered cosmetic aspects along with wound coverage and functional recovery in primary reconstruction. The results of aesthetic grading was 16.2 out of 20, and the secondary revision rate was reduced.
