    Journal of Traumatic Surgery, 2012
    Co-Authors: Xue Gang
    Abstract:

    Objective To assess the effect of reverse sural Neurovascular Island Flap in reconstructing soft tissue loss on foot and explore the effective measure for preventing from venous related complications.Methods The pedicle was reserved to be 3 cm in width,which was as same as the Flap in design.Small saphenous vein was ligated around the Flap rotation point.The Flap was transferred through open tunnel.Then rubber bandage was utilized to achieve depression after operation.Results All Neurovascular Island Flaps survived completely without any venous related complications.Conclusion The use of the reverse sural Neurovascular Island Flap for repairing soft tissue defects of the foot is safe and reliable,and the venous related complications could be prevented and managed.

  • Modified Heterodigital Neurovascular Island Flap for Sensory Reconstruction of Pulp or Volar Soft Tissue Defect of Digits.
    The Journal of hand surgery, 2019
    Co-Authors: Hui Wang, Xiaoxi Yang, Chen Chao, Yongxin Huo, Bin Wang, Wei Wang
    Abstract:

    Purpose We report the efficacy of a modified heterodigital Neurovascular Island Flap innervated by the dorsal branch of the proper digital nerve and the proper digital nerve, for repairing either pulp or volar defects in the fingers. Method We repaired 14 digits of 14 patients who had a complex defect involving soft tissue and digital nerve in the pulp or volar surface of the digit using the modified heterodigital Neurovascular Island Flap. Cases were divided into 2 groups: a pulp defect group including 5 thumbs and 1 little finger; and a volar defect group with a digital nerve defect, involving one thumb, 3 index and 3 middle fingers, and one ring finger. At the recipient site, nerve stumps of the PDNs in the pulp defect group were coapted with the proximal ends of the dorsal branch of the PDN and the proper digital nerve in the Flap. The distal and proximal ends of the PDN in the Flap were intercalated into the defect of the PDN in volar defect group, and the proximal end of dorsal branch of PDN in the Flap was also coapted to the proximal end of the proper digital nerve of the recipient finger. At the donor site, the defect of the proper digital nerve was repaired with nerve graft harvested from the proximal portion of the dorsal branch of the same proper digital nerve, and a full-thickness skin graft covered the donor site. Results All Flaps and the skin grafts of the donor site survived completely. At the final follow-up, 9 of 14 Flaps had a static 2-point discrimination result below the normal threshold ( Conclusions The modified heterodigital Neurovascular Island Flap is a useful and reliable treatment option for a digital pulp or volar defect, especially when the digital nerve defect requires repair. Type of study/level of evidence Therapeutic IV.

  • Applied anatomy of antegrade Neurovascular Island Flap from the same finger
    Chinese Journal of Hand Surgery, 2013
    Co-Authors: Xiao-hui Liao, Wei Wang, Ping Wang, Ya-di Guo, Cheng Zhu, Jie Min
    Abstract:

    Objective To investigate the micro-anatomical structures of the antegrade Neurovascular Island Flap and provide anatomical basis of using this Flap from the same finger for repairing finger pulp defects.Methods Twenty adult cadaver hand specimens were dissected under a surgical microscope.Anatomical structures of the Neurovascular bundle of the Flap were observed and the Flap advancing distance was measured.Results The advancing distance of the Island Flap was (16.7± 1.4) mm in the thumb,(18.5± 1.2) mm in the index finger,(19.7± 1.8) mm in the middle finger,(18.1 ± 1.0) mm in the ring finger and (15.8 ±1.2) mmin the little finger.Overall the Flap could be advanced about 1.5 to 2.0 cm.Another 0.5 cm advancement could be achieved when the metacarpophalangeal joint and proximal interphalangeal joint were flexed for 15° to 20°.The maximum advancing distance should not exceed 2.0 to 2.5 cm.Conclusion Advancement of antegrade neurovasctlar Island Flap from the same finger offers a sensate skin Flap for coverage of finger pulp defect.The surgical technique is simple,and the clinical results are satisfactory.It is an ideal method for reconstruction of thumb or finger pulp defects.

  • Transfer of Neurovascular Island Flap from the same finger for repairing pulp defect
    Zhongguo xiu fu chong jian wai ke za zhi = Zhongguo xiufu chongjian waike zazhi = Chinese journal of reparative and reconstructive surgery, 2006
    Co-Authors: Li-rong Zhou, Wei Wang
    Abstract:

    OBJECTIVE: To observe the clinical effects of Neurovascular Island Flap from the same finger for repairing pulp defect. METHODS: From November 2003 to February 2005, 32 pulp defects in 30 cases were covered with Neurovascular Island Flap from the same finger. There were 25 males and 5 females. The age ranged from 18 to 56 years. The operation was performed after debridement and 2-8 days antibiotics therapy. The defect area ranged from 1.5 cm x 1.2 cm to 3.5 cm x 2.1 cm. The Flap was harvested on the dorsal part of the finger ulnarly or radially. The distal end of the Flap should be more than 5 mm away from the nail base to avoid nail injury. The ventral and dorsal cut should not exceed the middle line respectively. The Flap size ranged from 2.0 cm x 1.5 cm to 4.0 cm x 2.5 cm. The donor site was covered with Flap of subdermal vascular plexus from the medial side of the upper arm. RESULTS: All 32 transferred Flaps survived after operation. There was no vascular crisis. Twenty-five cases were followed up from 2 to 8 months. The Flaps had good appearance and texture and blood circulation. Two-point discrimination was 7-10 mm. The function of finger motion was returned to normal. CONCLUSION: Transfer of Neurovascular Island Flap from the same finger offered a sensational skin Flap for reconstruction of pulp defect. The technique was simple, and the clinical result was satisfactory. It is an ideal method for reconstruction of thumb or finger pulp defects.

  • Repair of the thumb pulp loss with six Flaps: a long period follow-up
    Chinese Journal of Hand Surgery, 2006
    Co-Authors: Wang You-hua
    Abstract:

    To investigate the results of six Flaps for repair of the thumb pulp defects. Methods The 142 patients who had accepted thumb reconstruction with 6 Flaps before Dec, 2001 were made a long period follow-up . The subclavian pedicle Flap, the volar digital advancement Flap, the lateral digital Neurovascular Island Flap, the dorsal digital Flap, the approximate radial thenar Flap and the big toe skin Flap had been undergone for 142 patients, and summarized the results of 142 patients whose data were completely acquired, according to the shapes ,sweating, sensory and motor functions etc. Results The shapes , sweating and sensory of the thumb pulp with the subclavian pedicle Flap and the dorsal digital Flap repair were poor compared with the others Flaps. Conclusion The volar digital advancement Flap, the lateral digital Neurovascular Island Flap, the approximate radial thenar Flap and the big toe skin Flap were good methods for repair the thumb pulp defects, but the lateral digital Neurovascular Island Flap was more trauma procedure than the others, and influenced the sensory of donor site.

  • Ulnar Thumb Pulp Reconstruction Using the Anterograde Homodigital Neurovascular Island Flap
    The Journal of hand surgery, 2017
    Co-Authors: Valeriy Shubinets, River M. Elliott
    Abstract:

    The thumb ulnar pulp is a critical component of key pinch and precision manipulation. Injuries to this area should be reconstructed with robust, sensate tissue that restores bulk and contour. The existing reconstructive options, however, have substantial risks and drawbacks. We describe an anterograde homodigital Neurovascular Island Flap that provides both sensate and durable coverage of the ulnar thumb pulp. The Flap uses innervated glabrous tissue, limits donor site morbidity to the thumb and first web space, and does not require microvascular anastomoses or nerve coaptation. The Flap has been previously described for nonthumb fingertip injuries, but it has not been applied to the thumb. We discuss several important technical modifications that are essential to raising and insetting this Flap in the thumb, review potential pitfalls, and highlight key steps to ensuring judicious intraoperative decision making and success.
