The Second Toe Toe Toe Side Of Tandem Composite Tissue Flap Finger Defects In Basic And Clinicalresearch

Objective: Explore the second toe toe toe side of tandem composite tissue flap efficacy of vascular anatomy and clinical application of basic finger defects.Methods:Studies include basic research and clinical application of two parts. Basic research, including autopsy: In this study, six fresh adult lower extremity limb side, four side with red latex arterial perfusion, direct anatomical side after two thaw frozen corpse. Toe plantar artery anatomy under the microscope, the distal to the toe. With a vernier caliper to measure toe plantar artery caliber wear parts and support given. 16 refers to the 16 cases of clinical thumb, finger fingertip patient composite tissue defects, designed to toe plantar artery- A plica vascular pedicle fascia second toe toe toe side tandem composite tissue flaps were a tile repair.Results:All of the samples can be found in the toe plantar artery and its terminal branches of the nail bed and fibrous support. A toe plantar artery in the folds of nearly 7.6 ± 0.7mm at the terminal nail bed support issue, fibrous branches in armor folds nearly 3.3 ± 0.1mm at issue. Them with the epidermal side Periungual distance 3.8 ± 1.0mm. Terminal branches of the nail bed and fibrous branch diameter were 0.8 ± 0.2mm and 0.7 ± 0.1mm, toe plantar artery diameter was 1.4 ± 0.2mm. Clinical application of 16 cases, 16 cases of flaps survived up for 4 to 17 months, an average of 12 months. Finger excellent function, sensory recovery flaps grade S2-S3 +, lifelike appearance, nail growth in good shape for the area toenail grow well, no toe pain, no skin graft rupture occur.Conclusions: Terminal branches of the nail bed and fibrous plantar artery branch toe anatomical constant, designed to toe end artery- A plica vascular pedicle pedicle second toe toe toe side tandem composite tissue flaps were a tile repair fingertip composite tissue defects by area shape, and less damage for the area.
