One of the major advantages of microsurgical reconstruction for defects of the hand is that these techniques allow for selection of the most ideal tissue to reconstruct a particular defect, thus optimizing the functional and aesthetic outcome. The dorsalis pedis free flap is an excellent reconstructive tool for various hand reconstructions. It has a reliable vasculature with vessels that are relative large on a long pedicle. It provides thin pliable tissue and be innervated by deep peroneal nerve. Coupled with its thinness and pliability, it is ideal for innervated cover of critically sensitive area, especially such as the hand. Thus it can be used as a cutaneotendinous flap, or an osteocutaneous flap. Otherwise, the major criticism with this flap is related to its uncertain vascularity and the donor defect. It is the purpose of this paper to outline our technique of flap elevation and donor site closure and to indicate our current use of this flap in hand reconstruction. We have treated 10 cases (6 burn scar contracture cases, 4 acute hand trauma cases) of hand reconstruction from Dec. 3, 1997 to Mar. 4, 2004 using dorsalis pedis free flap. The key points for sucess in terms of a viable flap and acceptable donor site are the preservation of the critical dorsalis pedis-first dorsal metatarsal vascular axis and the creation of a viable bed for grafting. In addition, we substituted preserved superficial fat skin graft for split thickness skin graft and wet environment was offered for good graft take. Preserved superficial fat skin is defined as composite graft containing epidermis, dermis and superficial fat layer. With sufficient care in flap elevation and donor site closure, a good graft take of preserved superficial fat skin under wet environment can be achieved with no functional disability and minimal cosmetic deformity in donor site. This flap has proved itself to be a best choice for hand reconstruction.

The authors analyzed the clinical results of the reconstructive surgery for injuried hand with microsurgery in 33 patients, 35 cases at the department of orthopaedic surgery, school of medicine, Kyung Hee university from 1985 to 1992 and the results were as followings. 1. There were 31 men and 4 women who had a mean age of 23 years(range, 3 to 44 years) and the follow up evaluations averaged 19 months. 2. The causes of the injury were machinery injury in 25 cases, traffic accident in 2, frostbite in 4, burn in 3 and fall down in 1. 3. For the reconstructive procedure, scapular free flap was applied in 6 cases, radial forearm flap in 7, dorsalis pedis free flap in 4, neurovascular island flap in 6, gracilis free flap in 1, wrap around flap in 6, toe to thumb in 5. 4. 32 cases(91.4%)were successful in reconstructive surgery with microsurgery exept the failure of scapular free flap in 2 cases and dorsalis pedis free flap in 1. 5. The causes of failure in scapular free flap were infection in 1 case and thrombosis in 1. In dorsalis pedis free flap, the cause of failure was infection. In the analysis of above results, the reconstruction with microsurgery was effective procedure for reconstruction of injuried hand.

Reconstructive surgical procedures for hypopharyngeal and cervical esophageal defects have still a lot of technical defficulties and varieties to be performed as a optimal treatment according to the clinical situation patient faced. We have experienced a case of successful reconstruction of cervical esophageal defect, which was resulted from graft failure of free jejunal transfer in 43 year old male with eso-phagocutaneous fistula, using free fasciocutaneous dorsalis pedis flap. This article describes the review of our case and literature relevant the reconstructive maneuvers of cervical esophageal defects.

The extensor digitorum brevis (EDB) muscle island flap is a reliable, safe method for coverage of foot and ankle. There are many variation in approach such as curvilinear, zigzag, L-shaped or vertical longitudinal incision for exposure of the EDB muscle. These approaches use only single incision excluding the distal incision for exposure of the distal tendon. Since dorsalis pedis artery vascular bundle and sinus tarsi branch of the lateral tarsal artery both requires careful dissection, single incision alone may cause not only difficulty in exposure but also skin sloughing at donor site. So we tried to modify the approach into two parallel longitudinal incision, one for dorsalis pedis vascular bundle and the other for sinus tarsi branch exposure. The author treated 9 patient with EDB muscle flap. We used single incision in six patients, and two parallel incision in three patients. All the flap survived. In two parallel incision group, dissection was more easy and rapid. So we would like to suggest that two parallel longitudinal incision approach is better method than the single incision technique for exposure of the EDB muscle flap.

Purpose: The purpose of this study was to identify the change in foot care knowledge, self care behavior, and physiologic indexes after foot reflexomassage education program, and the related factors. Method: Data were collected from 20 patients who were visited out patients clinic. The change and difference were analyzed with non-parametric statistics. Result: There were significant differences in foot care knowledge(P=.001), self care behavior(P=.000), dosalis pedis blood flow volume (P=.011), skin temperature of foot(P=.001), dorsalis pedis pulse(P=.000), capillary filling time of foot (P=.000) between pre and post. The level of changes of foot care knowledge was significant differences according to admission experience (P=.049), and negative related to systolic blood pressure(P=.028). The level of changes of self care behavior was related to age(P=.049), that of dosalis pedis blood flow was significant difference according to smoking(P=.042), that of skin temperatureof foot(P=.002) and dosalis pedis pulse(P=.038) were significant difference according to weight. The level of changes of capillary filling time of foot was related to diagnosis period(P=.014). Conclusion: Foot-Reflexo-Massage education program is an effective nursing intervention to promote foot care in diabetic patients. And the related factors can be recommended for the management of diabetic patients.

Free flap reconstruction of the foot has become one of the standard procedures at the present time, but choice of a free flap for the soft tissue defect of the foot according to location and size remains controversial. We evaluated the results of free flap reconstruction for the soft tissue defects of the foot. Twenty seven free flaps to the foot were performed between May 1986 and December 2000 in the department of Orthopedic Surgery. Patient age ranged from 3 to 60 years. Male to female distribution was 20:7. Mean follow-up period was 30.5 months which ranged from 12 months to 60 months. The indications for a specific flap depended on the location and extension of the foot defect. In weight-bearing area and amputation stump, the authors chose the sensate (reinnervated) dorsalis pedis flaps (n=7) and sensate radial forearm flaps (n=2). In nonweight-bearing area including dorsum of the foot and area around Achilles tendon, we performed nonsensate (non-reinnervated) free flap reconstructions which included dorsalis pedis flaps (n=5), groin flap (n=1), radial forearm flaps (n=6), scapular flaps (n=4), latissimus dorsi flaps (n=2). Twenty-six flaps transferred successfully (96.3%). The sensate flaps which were performed in weight-bearing area and amputation stumps survived in all cases and recovered protective sensation. Mean two-point discrimination was 26 mm at the last follow up. As a conclusion, the selection of a proper flap depends on the location and extension of the foot defect and patient's age. Fasciocutaneous flap including radial forearm flaps and dorsalis pedis flaps were the best choice in nonweight-bearing area. The sensate free flaps which are performed in the weight-bearing area and amputation stumps can produce better outcome than nonsensate free flap.

Microsurgical reconstruction of the hand demands recovery of the sensation of the reconstructed free flap as well as microsurgeon's intelligence, technique and experience. Even with adequate soft tissue coverage and skeletal mobility, an insensate hand is prone to further injury and is unlikely to be useful to the patients. Authors have performed 8 cases of neurosensory free flaps in the hand, 4 cases of wrap around, 3 dorsalis pedis and 1 lateral arm flap, from July 1992 through June 1999 and followed up average 4 years and 4 months. Wrap around flap was performed for reconstruction of 4 cases of thumb, repairing deep peroneal nerve and superficial radial nerve by epineurial neurorrhaphy, and followed up for average 3 years and 10 months and calculated 9mm in the static 2 point discrimination test. Dorsalis pedis flap were 3 cases for reconstruction of the ray amputation, extensor tendon exposure and wrist exposure. Deep peroneal nerve and branch of the ulnar nerve was repaired by epineurial neurorrhaphy calculating 6mm and superficial peroneal nerve and superficial radial nerve averaging 18mm in the static 2 point discrimination test for follow up average 2 years and 9 months. Lateral arm flap was 1 case for reconstruction of the ray amputation in the hand repairing posterior cutaneous nerve to the arm to the superficial radial nerve calculating 20mm for follow up 6 years and 8 months.

Objectives: The pulse diagnosis to identify the symptoms has been considered important in Korean medicine. The position and character of disease would be confirmed by pulse diagnosis of left and right radial artery. This paper is to analyze the characteristics and differences of left and right blood vessels. Methods: In this study, left and right radial artery and dorsalis pedis artery was measured and analyzed by using condenser typed pulse analyzer. Commercially available pulse analyzer was used to measure the radial artery. The pulse wave was measured in 20 laboratory healthy men and women. The blood vessel aging degree and index of augmentation of blood vessel was obtained from the measured pulse wave graph and the characteristics and differences of the left and right blood vessel was analyzed. Results: The significant difference of pulse transit time between the right handed and non-right handed was not found. The correlation of radial artery and dorsalis pedis artery had no significant difference. By obtaining the blood vessel aging index (AGI) and augmentation index (AI) of blood vessel at the left and right radial artery, the significant difference between right handed and non-right handed was not found. Conclusions: The result of this study would help to explain the characteristic of blood vessel with respect to the left and right handed. We suggest that research of pulse wave of the left and right blood vessel using pulse analyzer should be needed in further study.

We report two patients whose acute soft tissue and tendon defects in the hand were treated by the dorsalis pedis tendocutaneous delayed arterialized venous flap between 1994 and 1997. The surviving surface area was 100% in both patients. The flap size was $10{\times}10cm\;and\;6{\times}6cm$. At two weeks postoperatively, active flextion and passive extension commenced, and progressive resistance exercises were performed for an additional 5 weeks. Flaps showed a similar color match and skin texture compared with the normal skin of the hand. Advantages of the tendocutaneous delayed arterialized venous flap are developing a larger flap than can be obtained with pure venous flap or arterialized venous flap, increasing survival rate of the arterialized venous flap which permits using a composite flap, preservation of main artery of the donor site, taking thin non-bulky tissue and easy elevation without deep dissection. The disadvantages are the requirement of a two stage operation, donor site scarring and weak extension of the toe.
