A novel surgical method for total nail ablation: Use of triple flap technique

<p>Total nail ablation for the treatment of onychodystrophies can be performed by using chemicals, surgical resection or laser ablation of nail matrix.<strong> </strong>A female patient with bilateral severe onychodystrophy as a result of inadvertent previous nail surgeries was treated surgically. Proximal complete nail matrix resection and distal 10 mm wide transverse strip partial nail bed resection were performed. A 5 mm wide transverse strip of nail bed was left intact proximally. Proximal nail matrix defect was closed by using the skin of proximal nail fold. The distal nail bed defect was reconstructed by using triple flap technique which was composed of a main central advancement flap containing ventral toe skin and two side flaps containing nail fold skin. The patient healed without any problem and her nail problem was treated successfully. The cosmetic appearance of her first toes was acceptable. Surgical nail ablation followed by volar skin coverage of dorsal surface of the distal phalanx bone by using triple flap technique is an effective surgical treatment method for the correction of advanced nail plate deformities requiring total nail ablation. </p>

Effects of the Stress Annealing on Magnetic Properties of Nanocrystalline Fe73.5Cu1Nb3Si15.5B7 Alloy

Magnetic properties of nanocrystalline Fe73.5Cu1Nb3Si15.5B7 ribbons with anisotropy induced by stress-annealing at different temperatures have been investigated.The results show that the magnetic properties were improved with the increase of temperature and excellent DC bias property was obtained after annealing above 580°C due to the transverse strip domain structure.
