Introduction: The hand and wrist are particularly susceptible to electrical burn. Skin defect with damage or exposure of underlying vital structure requires coverage by skin flap especially in case of the need for late reconstruction. We are reporting 4 cases of electrical burned hand treated by posterior tibial arterial free flap. The commonly used skin flaps such as scapular flap or groin flap are too bulky so that they are not satisfactory in function and cosmetic appearance. So we tried to cover them with a more thin skin flap. Materials and Method: From January 2002 to June 2003, four cases of hand and wrist electrical burn were covered using posterior tibial arterial free flap. All the cases were due to high voltage electrical burn. Age ranged from 31 years to 38 years old and all the cases were male patients. Recipient sites were 2 wrist, one thenar area and one knuckle of 2.3rd MP joint. Additional procedures were flexor tenolysis (simultaneous), FPL tenolysis and digital nerve graft (later) and extensor tendon reconstruction (later). Result: All the flap have survived totally without any complication including circulatory concern about the donar foot. Posterior tibail arterial free flap was so thin that debulking procedure was not required. Conclusion: For skin coverage of the hand & wrist region, posterior tibial arterial free flap have many advantages such as reliable anatomy, easy dissection and easy anastmosis with radial or ulnar artery and possibility of sensory flap. The most helpful advantage for hand coverage is its thinness. So we think this flap is one of the very useful armamentarium for reconstructive hand surgery.

Objectives : Wrist ganglion is one of the most common diseases on the wrist joint. So far acupuncture, medication, drainage and local anesthetic excision therapy have been used for this disease, but the development of more effective treatment method is being expected because of frequent recurrence and side effect. Considered that most ganglion is polycystic, on the basis of classic centro-square acupuncture, newly transformed centro-square acupuncture was applied to this report. Methods : All the patients with wrist ganglion was divided into two groups. Newly transformed centro-square acupuncture was app(ied to one group composed of 11 patients and classic centro-square acupuncture to the other group with 19 patients. Classic centro-square acupuncture is made up of slanting and straight insertion. the former is a method that tips of 4 needles are inserted from the outersurface of wrist ganglion oriented to the center of the ganglion, the latter is that tip of one needle is inserted on the center of the ganglion straightly. In the newly transformed centro-square acupuncture, straight insertion of dry needle was taken place of by syringe needle in order to drain phlegm. In this report, classic and newly transformed centro-square acupuncture were used somewhat differently from original ones. Moxibustion was applied after removing all the needles. In newly transformed centro-square acupuncture, moxibustion was also applied after drainage of phlegm and slanting insertion. Results : 1. Wrist ganglion was frequently developed around the acupoint of Tae-Yeon(Tai Yuan, LU9) and Yang-Ji(Yang Chi, TE4) and the difference between occurrence of development on the left and right hand had no significancy. 2. The mean number of treatment for recovery : The newly transformed centro-square acupuncture had fewer treatment than classic one. 3. The newly transformed centro-square acupuncture was more effective than classic one. 4. As a result of following up 6 to 72 months after wrist ganglion had been eliminated, there was no recurrence. Conclusion : In the treatment of wrist ganglion, newly transformed centro-square acupuncture can be regarded as more useful method in the clinical practice, because it has comparatiely shorter duration of treatment and is more effective.

Purpose: High tension electrical injuries result in major tissue(eg. bones, tendons, vessels and nerves) destruction. Therefore, the management of mutilating wrist caused by electrical injuries still represents a challenge. There are various approaches to this problem including local and regional flaps as well as pedicled distant flaps and microsurgical free tissue transfer. Although it has not gained wide acceptance, because of the technically demanding dissection of the pedicle, posterior interosseous flap is now well accepted for the reconstruction of hand and wrist in hand surgery. The principal advantages of this flap are minimal donor site morbidity, minimal vascular compromise, one stage operation. This flap also offers the advantages of ideal color match and composition. In this report, we describe our experience with the reverse posterior interosseous island flap for reconstruction of mutilating wrist with main vessel injuries. Methods: From October, 2004 to June, 2006, we treated 11 patients with soft tissue defects and main vessel injuries on the wrist that were covered with reverse posterior interosseous island flap. Results: These 11 patients were all male. The ages ranged from 27 to 67 years(mean age 41.75) and the follow-up period varied from 4 to 19 months. Complete healing of the reverse posterior interosseous island flaps were observed in 11 patients(12 flaps). The majority of these flaps showed a certain degree of venous congestion, which in a flap was treated with medical leech. 1 flap has partial necrosis owing to sustained venous congestion, requiring secondary skin graft. flap size varied from $3.5{\times}8cm$ to $10{\times}12cm$(mean size $6.4{\times}8.9m$). The donor site defect was closed directly in 5 flaps, and by skin graft in 7 flaps. Conclusion: We found that the reverse posterior interosseous island flap is reliable and very useful for reconstruction of mutilating wrist and we recommend it as first choice in coverage of soft tissue defects in the wrist with electrical arc injuries.

This paper describes the development of a six-axis force/moment sensor with rectangular taper beams for an intelligent robot's wrist and ankle. In order to accurately push and pull an object with an intelligent robot's hand, and in order to safely walk with an intelligent robot's foot, the robot's wrist and ankle should measure three forces Fx, Fy, and Fz, and three moments Mx, My, and Mz simultaneously from the mounted six-axis force/moment sensor to the intelligent robot's wrist and ankle. Unfortunately, the developed six-axis force/moment sensor utilized in other industrial fields is not proper for an intelligent robot's wrist and ankle in the size and the rated output of the six-axis force/moment sensor. In this paper, the structure of a six-axis force/moment sensor with rectangular taper beams was newly modeled for an intelligent robot's wrist and ankle, and the sensing elements were designed by using the derived equations, following which the six-axis force/moment sensor was fabricated by attaching strain-gages on the sensing elements. Moreover, the characteristic test of the developed sensor was carried out by using the six-component force/moment sensor testing machine. The rated outputs from the derived equations agree well with those from the experiments. The interference error of the sensor is less than 2.87%.

The wrist and forearm are a frequently damaged area in high tension electrical injury as an input or output of the current. Electrical burns affecting the wrist and forearm may produce full thickness necrosis of the skin and damage deep vital structures beneath the eschar, affecting the local tendons, nerves, even bones and joints which result in serious dysfunction of the hand. From January 1997 to December 2001, we had treated 20 patients with high tension electrical burn in the wrist and forearm using anterolateral thigh free flap. Average follow up period were 24 months and we get satisfactory results both in functional and aesthetic aspects. This flap is considered useful in one-stage reconstruction of wide and large soft tissue defect combined with arterial injuries.

This paper deals with a Capstone Design project which is a wearable haptic wrist massage device design carried out within the 'Designeer' education program. Following design thinking process is recommended throughout a year in order to ensure a desirable, feasible and viable product. Dealing with a real problem of the field requires open-minded and flexible attitudes both from students and professors. Integrating design in an engineering project does not mean always making better looking product. User experience design allows wider opportunity to engineers to deal with design. A case study of developing a wearable wrist massage device shown in this paper demonstrate haptic design and how haptic properties can be optimized to offer best user experience of hand massaging. This study identified that starting lateral pressure movements from the center in larger area using air tubes gives better feeling as self-massage using wrist wearing devices.
