Purpose: We had proceeded seven iIpsilateral dorsalis pedis vascularized pedicle flaps in the distal leg and foot to cover the restricted size defects and followed-up average for 5 years and 9 months to evaluate the survival rate, neurosensory function and cosmesis in final results. Materials and Methods: From January 1999 through October 2012, we have performed iIpsilateral dorsalis pedis vascularized pedicle flaps in the distal leg and foot to cover the restricted size defect (average around $3.6{\times}2.4cm$) in 7 cases and average age was 41.6 years (21.5 to 59.0 years). Lesion site was posterior heel in 4 cases, distal anterior leg in 3 cases. Donor structure was the dorsalis pedis artery and the first dorsal metatarsal vessel and deep peroneal nerve in 3 cases and the dorsalis pedis artery and the first dorsal metatarsal vessel in 4 cases. Results: Seven cases (100%) were survived and defect area was healed with continuous dressing without skin graft. The sensory function in the neurovascular flap was restored to normal in 3 cases. Cosmesis was good and fair in 7 cases (85.7%). Conclusion: Ipsilateral dorsalis pedis vascularized pedicle flap in the distal leg and foot is one of the choice to cover the exposed bone and soft tissues without microsurgical procedure.

Purpose: We present clinical usefulness of saphenous neurocutaneous island flap for reconstruction of soft tissue defect of the lower leg, especially anteromedial aspect, including foot and ankle. Materials and Methods: Thirteen cases of soft tissue defects in the lower leg including foot and ankle which were 6 cases of pretibial area, 2 cases of anteromedial aspect of distal two third, 2 cases of ankle, and 3 cases of foot were treated saphenous neurocutaneous island flap. They were proximally based flap 3 cases and distally based flap 10 cases. Clinically the flaps ranged in size from $4{\times}5\;cm$ to $6{\times}12\;cm$. Results: All of the flaps except 1 case survived completely. Three cases, however, had marginal necrosis. One case of flap failure was proximal tibia fracture accompanied with injury of the flap pedicle which was difficult in flap elevation, subsequently. Conclusion: The saphenous neurocutaneous island flap is a simple, reliable procedure with a versatility for soft tissue coverage of the lower leg, especially anteomedial aspect, including foot and ankle. In case of another injuries accompanied near the saphenous nerve, careful attention should be made.
Purpose : Soft tissue defect and exposed tendons and bones with concomitant infection in the foot and lower leg have to be covered with vascularized flap as the one stage treatment. Authors have performed 6 cases of pedicled dorsalis pedis island flaps under the loupes magnification and evaluated the benefits. Materials and methods : From 1994 through 2003, we have performed 6 pedicled dorsalis pedis island flaps for reconstruction of soft tissue defects in the foot and lower leg. The causes were trauma in 3 cases, skin necrosis and secondary infection after Achilles tendon repair in 2 cases and acute osteomyelitis in 1 case. Average age was 38 years and 5 cases were male and 1 female. The results of the procedure was evaluated by survival of the island flap, comfort in putting on shoes and walking, comfort in the donor site, comfort in the recipient site and range of motion of the ankle joint. Results : All pedicled dorsalis pedis island flaps survived except 1. Three cases felt discomfort in the dorsum of foot as the donor site and 1 case of the Achilles tendon ruptured and repaired showed limited dorsiflexion of ankle joint. Conclusion : Nonmicrosurgical pedicled dorsalis pedis island flaps under the loupes magnification are one of the useful treatment methods because procedure is rapid, survival is confident and overall reconstructive results are good.

A wide range of applications for Foot Print Recognition System is discussed in this paper. The whole concept works under the principle that foot print is a parameter associated with biometrics that is very common as well as distinct. Its foremost application is at the government hospitals in the under developed and third world nations where there aren't the best of facilities. This system can be applied in the maternity ward of the hospitals for the identification or differentiation of the infants. Till date there has been no specialized system adopted for this purpose. The Foot Print Recognition System will overcome all the defects of any biometrics when applied here. Since the child will be very delicate for an iris scan and it will not be able to open its eyes wide or to correctly place its finger print on the sensor since the hands of a new born infant will be closed for a while. The Foot Print Recognition system can also be implemented in temples where there are cases of theft often reported. This can be used to grant access to the karpagraham of the deity by authorized users alone. These 2 applications of FPRS are discussed in this paper.
Purpose : Our clinical experiences in distally based sural artery island flap is presented to show the usefulness and the reliability as an alternative to flaps currently used for defect in lower extremity. Materials and Methods : From February 1998 to September 2001, nine cases of soft tissue defects in the lower leg, the foot, and around the ankle were treated with distally based sural artery island flap. The cause of the wound was trauma in 6 cases, and osteomyelitis in 3 cases. Defects were located at the lower leg in 2 cases, at the foot in 3 cases and around the ankle in 4 cases. The results were retrospectively analyzed. Results : The defect size ranged from $3{\times}3cm\;to\;20{\times}3cm$. Among 9 cases, 7 cases survived and 2 cases were failed. Flap failure was due to not including the deep fascia in one case and due to extensive soft tissue damage in the other case. Both failed cases were reoperated with the split thickness skin graft. Conclusion : The advantages of distally based sural artery island flap follows (1) reliable blood supply, (2) ease of flap elevation, (3) preservation of the major arteries, (4) less donor site morbidity. Owing to the advantages of this flap, we think it is useful for the soft tissue coverage of the lower leg, the foot and around the ankle. Also we believe it will continue to gain acceptance and use in the majority of lower leg reconstruction.

Background The distally based sural artery flap is a reliable, local reconstructive option for small soft tissue defects of the distal third of the leg. The purpose of this study is to describe an adipofascial flap based on a single sural nerve branch without sacrificing the entire sural nerve, thereby preserving sensibility of the lateral foot. Methods The posterior aspect of the lower limb was dissected in 15 cadaveric limbs. Four patients with soft tissue defects over the tendo-achilles and ankle underwent reconstruction using the adipofascial flap, which incorporated the distal peroneal perforator, short saphenous vein, and a single branch of the sural nerve. Results From the anatomical study, the distal peroneal perforator was situated at an average of 6.2 cm (2.5-12 cm) from the distal tip of the lateral malleolus. The medial and lateral sural nerve branches ran subfascially and pierced the muscle fascia 16 cm (14-19 cm) proximal to the lateral malleolus to enter the subcutaneous plane. They merged 1-2 cm distal to the subcutaneous entry point to form the common sural nerve at a mean distance of 14.5 cm (11.5-18 cm) proximal to the lateral malleolus. This merging point determined the pivot point of the flap. In the clinical cases, all patients reported near complete recovery of sensation over the lateral foot six months after surgery. All donor sites healed well with a full range of motion over the foot and ankle. Conclusions The distally based sural artery adipofascial flap allowed for minimal sensory loss, a good range of motion, an aesthetically acceptable outcome and can be performed by a single surgeon in under 2 hours.
Purpose: Open fractures of the foot and ankle require prompt repair of the wound due to the complexity of anatomy, insufficiency of soft tissues and inadequate blood supply. Early flaps and skin grafts are used for this purpose yet general condition of the patient as well as local wound environment often precludes such treatment options. Vacuum- Assisted Closure (VAC) is recently being used in such cases. This study was done to validate the use of VAC together with silver antimicrobial dressing materials in contaminated open fracture wounds. Materials and Methods: We have selected 10 patients with Gustillo-Anderson type III open fractures of the foot & ankle treated with VAC and silver antimicrobial dressing materials from March 2007 to January 2008. The relationship between duration of treatment with wound size, contamination, and degree of soft tissue damage was analyzed. Results: The average age of patients was 36.6 years. The average amount of VAC application time was 23.4 days. Silver dressing materials were used for 16.8 days. Average wound healing time was 51.9 days. Statistically significant relationship was found between wound size, VAC application time and silver dressing material application time. No complications such as osteomyelitis were found after treatment. Conclusion: VAC technique is recently being used in open fractures with wide skin and soft tissue defects, producing good results. A wide array of dressing materials such as silver dressing is in development. We have incorporated the VAC technique together with silver dressing materials in the treatment of open fractures and achieved complication free results.

Purpose: Various kinds of local flap or free flap have been used for coverage for soft tissue defects with bone exposure over the ankle and dorsum of foot. Adipofascial flaps, nourished by vascular plexuses of the subcutaneous tissue and deep fascia originating from the local perforators of the major vessels, appear particularly to be indicated for the reconstruction of these areas. Our experience with this flap on the dorsum of foot and ankle has also been quite encouraging. Methods: The design of the flap is determined by the size and the location of the defect. The base of the flap is chosen depending on the availability of the soft tissue around the defect. The ratio of the area of the flap to the area of the base wound be more reliable to predict the survival of the turnover flap by the conventional length-to-width ratio. Nineteen patients with defect over the dorsum of the foot and ankle were resurfaced with adipofascial turn-over flaps and skin graft. Results: The average age of the patients was 38.2 years(3 - 81 years). The flap size was from $2{\times}3cm$ to $8{\times}5cm$. The average follow-up time was 6 months. All flaps survived completely except one case who suffered distal necrosis of the flap. The additional skin graft was required for partial skin loss in the five cases. Other functional impairment was not noted. Conclusion: Dissection of the local adipofascial turnover flap is quite easy, quick, requires less time and sacrifice of surrounding muscle itself, and maintains major arteries. In most cases, donor-site morbidity is minimal with an acceptable scar, and both functional and esthetical results were satisfactory. Therefore, Adipofascial flap could be an option for the difficult wounds around the foot and ankle.

Background In the extremities of premature infants, the skin and subcutaneous tissue are very pliable due to immaturity and have a greater degree of skin laxity and mobility. Thus, we can expect wounds to heal rapidly by wound contraction. This study investigates wound healing of full-thickness defects in premature infant extremities. Methods The study consisted of 13 premature infants who had a total of 14 cases of full-thickness skin defects of the extremities due to extravasation after total parenteral nutrition. The wound was managed with intensive moist dressings with antibiotic and anti-inflammatory agents. After wound closure, moisturization and mild compression were performed. Results Most of the full-thickness defects in the premature infants were closed by wound contraction without granulation tissue formation on the wound bed. The defects resulted in 3 pinpoint scars, 9 linear scars, and 2 round hypertrophic scars. The wounds with less granulation tissue were healed by contraction and resulted in linear scars parallel to the relaxed skin tension line. The wounds with more granulation tissue resulted in round scars. There was mild contracture without functional abnormality in 3 cases with a defect over two thirds of the longitudinal length of the dorsum of the hand or foot. The patients' parents were satisfied with the outcomes in 12 of 14 cases. Conclusions Full-thickness skin defects in premature infants typically heal by wound contraction with minimal granulation tissue and scar formation probably due to excellent skin mobility.

Soft tissue defect on heel area of the foot present difficult problems particularly because of anatomic property of plantar surface of the foot. There is a paucity of available local tissue in the foot for coverage. In addition to having little expandable tissue, the foot's plantar surface has a unique structure, making its replacement especially challenging. Plantar skin is attached to the underlying bone by fibrous septa, preventing shear of the soft-tissue surfaces from the underlying skeleton. Plantar surface of foot is in constant contact with the environment. Protective sensibility also would be maintained or restored in the ideal reconstruction. So the ideal flap for reconstruction of the heel should include thin, durable hairless skin with potential for reinnervation. The aim of this article is to present a clinical experience of free lateral arm neurosensory flap for reconstruction of the heel. From March 1995 to December 1997, a total 16 lateral arm free flaps were performed to soft tissue defects on the weight-bearing area of the hindfoot. we used tibial nerve as recepient nerve in 11 and calcaneal branch of tibial nerve in 5 for restoration of sensibility of flap. All cases survived completely. A static two-point discrimination of 14 to 34mm was detected in the flap. Radial nerve palsy which was caused by hematoma in donor site occured in one case, but recorverd in 3 weeks later completely. In conclusion, the lateral arm free flaps are versatile, reliable and sensible cutaneous flap and especially indicated for soft tissue defect on plantar surface of the hindfoot which are not good indications for other better-known flaps.
