Purpose: Fingertip amputations are the most common type of upper limb amputations. Composite grafting is a simple and cost-effective technique. Although many factors have investigated the success of composite grafting, the success rate is not high. Therefore, this study was conducted to investigate whether the microscopic procedure process during composite grafts improves the success rate. Materials and Methods: Thirteen cases of unreplantable fingertip amputation underwent a microscopic resection procedure for composite graft in the operating room. The principle of the procedure was to remove the least devitalized tissue, maximize the clean tissue preservation and exact trimming of the acral vessel and to remove as many foreign bodies as possible. Results: All fingertips in the thirteen patients survived completely without additional procedures. Conclusion: Composite grafting allows for the preservation of length while avoiding the donor site morbidity of locoregional flaps. Most composite grafts are performed as quickly as possible in a gross environment. However, we take noticed the microscopic resection. This process is thought to increase the survival rate for the following reasons. First, the minimal resection will maximize the junction surface area and increase serum imbibition. Second, sophisticated trimming of injured distal vessels will increase the likelihood of inosculation. Third, accurate foreign body removal will reduce the probability of infection and make it possible to increase the concentration and efficiency in a microscopic environment. Although there is a need for more research into the mechanisms, we recommend using a composite graft under the microscopic environment.
Pulp and palm of the hand and heel of the sole are anatomically unique. Satisfactory reconstruction of these areas presents the plastic surgeon with many challenges and requires durable and sensible skin coverage, minimal donor morbidity and reliable operative procedure. We presents 7 clinical cases of sensate instep free flap transfer in this paper during the last 2 years. Three cases were soft tissue defects due to crushing and avulsion injury on the pulp of finger. 1 case was unstable scar and redundant flap after reconstruction of soft tissue dect of palm and 1 case was contracture of first web of hand. One case was a soft tissue defect due to avulsion injury on heel. Lastly, one case was chronic osteomyelitis with open wound on lateral malleolar area. Follow-up period ranged from 3 months to 2 years. Through the whole follow-up period, all flaps were viable and durable to persistant stress or weight bearing and were sensible enough to porotect the recocstructed area from injuries and maintain functions. In conclusions, the instep free flap should be considered as a valuable tool in reconstruction of hand and extremity requiring durability and sensation.
To assess the status of industrial injuries, a large scale textile company located around Taegu city was selected. And it was investigated from January 1981 to December 1982. After the department for workers safety was established, frequency rate of injury was 9.70 in 1981 and 4.15 in 1982, incidence rate per 1,000 workers was 27.11 in 1981 and 12.96 in 1982, and then, intensity rate was 0.33 in 1981 and 0.01 in 1982. The average duration of working loss was 36.64 days in 1981 and 3.34 in 1982. The incidence rate per 100 workers was 2.3 in annual average, 2.7 in men and 2.0 in women. The monthly incidence rate per 1,000 workers was highest as 3.6 in June; daily incidence rate, lowest as 1.8 on Sunday; and the highest as 14.7 from 10 to 12 o'clock in a day. The frequency by injured parts of body was highest as 42.3% on finger and 14.4% on the other part of hand, and the lower extremities as 14.4% followed. According to the kind of injuries, the laceration was the highest as 46.1%, the next was contusion as 15.4%, and the third was superficial injuries as 6.7%, According to the cause of injuries, the machinery accidents showed the highest as 47.1% and the accidents due to hand tool followed as 16.3%. By underlying cause of injuries, the environmental factors were 13.5% and the human factors 86.5%. The psychologic factors among human factors were the most common as 60.6%.

Lesch-Nyhan syndrome is a rare X-linked recessively inherited disorder, caused by complete absence or decrease in activity of hypoxanthine guanine phosphoribosyl transferase(HPRT), an enzyme involved in purine metabolism. This enzyme deficiency gives rise to nephropathy symptoms, such as hyperuricosuria and hyperuricemia by excessive uric acid production and neuropathy symptoms, such as mental retardation, choreoathetosis and self mutilation behavior. Patients with Lesch-Nyhan syndrome have tendency to bite their lip, tongue and finger. In severe cases, partial or even total amputation of tongue or finger occur. Self-inflicted bites are often complicated by secondary infection to the injured site as well as pain. Furthermore tissue loss by biting results in esthetic problems. The dental management of self mutilation includes treatment with appliances such as soft mouth guard or lip bumper, extraction of all the teeth, and orthognathic surgery. We report a case of a 13 year-old boy with Lesch-Nyhan syndrome, who severely injured himself on his tongue. At first, conservative treatment using soft mouth guard was considered, but it could not prevent trauma on his tongue. Therefore, extraction of the lower anterior and posterior teeth was carried out.

Background Pediatric hand burns are a difficult problem because they lead to serious hand deformities with functional impairment due to rapid growth during childhood. Therefore, adequate management is required beginning in the acute stage. Our study aims to establish surgical guidelines for a primary full-thickness skin graft (FTSG) in pediatric hand burns, based on long-term observation periods and existing studies. Methods From January 2000 to May 2011, 210 patients underwent primary FTSG. We retrospectively studied the clinical course and treatment outcomes based on the patients' medical records. The patients' demographics, age, sex, injury site of the fingers, presence of web space involvement, the incidence of postoperative late deformities, and the duration of revision were critically analyzed. Results The mean age of the patients was 24.4 months (range, 8 to 94 months), consisting of 141 males and 69 females. The overall observation period was 6.9 years (range, 1 to 11 years) on average. At the time of the burn, 56 cases were to a single finger, 73 to two fingers, 45 to three fingers, and 22 to more than three. Among these cases, 70 were burns that included a web space (33.3%). During the observation, 25 cases underwent corrective operations with an average period of 40.6 months. Conclusions In the volar area, primary full-thickness skin grafting can be a good indication for an isolated injured finger, excluding the web spaces, and injuries of less than three fingers including the web spaces. Also, in the dorsal area, full-thickness skin grafting can be a good indication. However, if the donor site is insufficient and the wound is large, split-thickness skin grafting can be considered.
Purpose: We evaluated the physical stress and pain to the musculoskeletal system of a dental practitioner when engaging in a dental scaling training exercise to prevent the development of musculoskeletal injuries. Methods: The 18 female (average age: 21$\pm$1 years) subjects were voluntarily picked from a group of juniors who have completed a one-and-a-half year training course that includes training exercises on the dentiform and on live subjects (other trainees). The test is done by measuring pain, activity, grip strength, and finger dexterity for each subject's hand and wrist. Before the test all subjects were confirmed to be right-handed and were informed of the study and its objective. Measuring was done before and after each subject performed dental scaling for one hour using the scaler and the curet. Results: Pain levels increased for both hand and shoulders, but hand pain was often greater than shoulder pain. Grip strength significantly declined in the right hand but not the left. For joint mobility, the flexion and the extension for the shoulder joint did not change; but the range of motion for both wrist joints significantly increased. For the dexterity test, both hands showed increased dexterity after the exercise. Conclusion: Dental scaling can affect the shoulders and wrists/hands. Therefore, a musculoskeletal injury prevention program for dental practitioners, which may include encouraging them to assume correct body posture when at work, must be sought. This study evaluated only the shoulders, wrists, and hands; but future studies should include areas such as the cervical area, the back, and the lower limbs.

Background : Electrical burns are one of the most devastating types of injuries, and can be characterized by the conduction of electric current through the deeper soft tissue such as vessels, nerves, muscles, and bones. For that reason, the extent of an electric burn is very frequently underestimated on initial impression. Methods : From July 1999 to June 2006, we performed 15 cases of toe tissue transfer for the reconstruction of finger defects caused by electrical burns. We performed preoperative range of motion exercise, early excision, and coverage of the digital defect with toe tissue transfer. Results : We obtained satisfactory results in both functional and aesthetic aspects in all 15 cases without specific complications. Static two-point discrimination results in the transferred toe cases ranged from 8 to 11 mm, with an average of 9.5 mm. The mean range of motion of the transferred toe was $20^{\circ}$ to $36^{\circ}$ in the distal interphalangeal joint, $16^{\circ}$ to $45^{\circ}$ in the proximal interphalangeal joint, and $15^{\circ}$ to $35^{\circ}$ in the metacarpophalangeal joint. All of the patients were relatively satisfied with the function and appearance of their new digits. Conclusions : The strategic management of electrical injury to the hands can be both challenging and complex. Because the optimal surgical method is free tissue transfer, maintenance of vascular integrity among various physiological changes works as a determining factor for the postoperative outcome following the reconstruction.

Background Volar plate avulsion fracture of the proximal interphalangeal (PIP) joint is one of the most common hand injuries. In this study, we divided patients into two groups: patients with pure volar plate avulsion fracture, and patients with volar plate avulsion fracture concomitant with collateral ligament rupture. The purpose of this study was to compare long-term surgical outcomes between the two groups. As a secondary measure, the Mitek bone anchoring and polydioxanone (PDS) bone suturing techniques were compared. Methods A single-institutional retrospective review of the surgical treatment of volar plate avulsion fracture was performed. The cases were divided into those with pure volar plate avulsion fracture (group A, n=15) and those with volar plate avulsion fracture concomitant with collateral ligament rupture (group B, n=15). Both groups underwent volar plate reattachment using Mitek bone anchoring or PDS bone suturing followed by 2 weeks of immobilization in a dorsal protective splint. Results The average range of motion of the PIP joint and extension lag were significantly more favorable in group A (P<0.05). Differences in age; follow-up period; flexion function; visual analog scale scores; disabilities of the arm, shoulder, and hand scores; and the grip strength ratio between the two groups were non-significant. No significant differences were found in the surgical outcomes of Mitek bone anchoring and PDS bone suturing in group A. Conclusions Overall, the surgical outcomes of volar plate reattachment were successful irrespective of whether the collateral ligaments were torn. However, greater extension lag was observed in cases of collateral ligament injury.
Purpose: Many fingertip injuries are associated with nail injury and it is hard to repair to original shape due to its unique characteristic. Mucosal graft is used for a defect of the nail bed injury. Hereby, we introduce a DAP flap and buccal mucosal graft, with which we could reduce the defect size of the injured fingertip and donor site morbidity at the same time, without any need for harvesting additional skin from other part of hand. Also, mucosal graft makes good cosmetic and functional outcome of nail. Methods: This method was performed in a 56-year-old man with fingertip injury on dorsal side of left thumb due to electrical saw. First, DAP flap was performed on the injured finger to reduce the size of the defect of fingertip and cover the bone exposure. Second, nail bed part of the DAP flap was de-epithelized and buccal mucosal graft was done from left side of intraoral cavity wall. Results: Flap and graft survived without any necrosis but some nail bed could not be covered with flap due to insufficient flap size. All wounds healed well and did not present any severe adversary symptoms. Conclusion: DAP flap with mucosal graft is an effective method that we can easily apply in reconstruction of fingertip injury. We suggest that the combination of the two procedures makes good functional and cosmetic outcome compared to the usual manner, especially in cases of nail bed injury without distal phalanx bone defect.

Background Digital amputation is a common upper extremity injury and can cause significant impairment in hand function, as well as psychosocial stigma. Currently, the gold standard for the reconstruction of such injuries involves autologous reconstruction. However, when this or other autologous options are not available, prosthetic reconstruction can provide a functionally and aesthetically viable alternative. This study describes a novel technique, known as a tripod titanium mini-plate, for osseointegrated digit prostheses, and reviews the outcomes in a set of consecutive patients. Methods A retrospective review of patients who underwent 2-stage prosthetic reconstruction of digit amputations was performed. Demographic information, occupation, mechanism of injury, number of amputated fingers, and level of amputation were reviewed. Functional and aesthetic outcomes were assessed using the quick disabilities of the arm, shoulder, and hand (Q-DASH) scale and a visual analog scale (VAS) score, respectively. In addition, complications during the postoperative period were recorded. Results Seven patients were included in this study. Their average age was 29 years. Five patients had single-digit amputations and 2 patients had multiple-digit amputations. Functional and aesthetic outcomes were assessed using the Q-DASH score (average, 10.4) and VAS score (average, 9.1), respectively. One episode of mild cellulitis was seen at 24 months of follow-up. However, it was treated successfully with oral antibiotics. No other complications were reported. Conclusions When autologous reconstruction is not suitable for digit reconstruction, prosthetic osseointegrated reconstruction can provide good aesthetic and functional results. However, larger series with longer-term follow-up are required in order to rule out the possibility of other complications.
