  • A Soil Nail is a structural element which provides load-transfer to the ground in excavation reinforcement applications. The nail may simply consist of a steel tendon, but most commonly the tendon is encapsulated in a cement grouted body to provide corrosion protection and improved load- transfer to the ground. For temporary excavation support in a congested urban area, the steel bar of Soil Nails should be removed to get permission of the private land to install Soil Nails. Several removable nail systems were developed and evaluated by pull-out load tests. The Soil Nail pull-out tests were performed on five nails installed in soft and hard rock at a 00 housing-redevelopment area in seoul. Two nails are plastic socket type and two are complex socket type mixed steel and plastic. The nail was 0.1mm in diameter, 4m long. In this study verification tests, and steel bar removing tests of plastic socket type nails and complex socket type nails were performed and presented.

  • Background: Facial palsy treatment comprises static and dynamic techniques. Among dynamic techniques, local temporalis transposition represents a reliable solution to achieve facial reanimation. The present study describes a modification of the temporalis tendon transfer using a cryopreserved fascia allograft. Case presentation: Between March 2015 and September 2018, seven patients with facial palsy underwent facial reanimation with temporalis tendon transfer and fascia lata allograft. Patients with long-term palsy were considered, and both physical and social functions were evaluated. The mean follow-up time was 21.5 months. No immediate complications were observed. Patients reported improvement in facial symmetry both in static and dynamic. Improvement was noticed also in articulation, eating, drinking, and saliva control. The Facial Disability Index revealed an improvement both in physical function subscale and in the social/well-being function subscale. Conclusions: This modified orthodromic technique allows to reduce the operative time and the risk of complications connected to the use of autologous tissues. The use of the cryopreserved fascia allografts from cadaveric donors seems to provide promising and long-standing results in the treatment of facial palsy.

  • In this study, the static load test and the load transfer test were carried out to evaluate the structural performance of the circular anchorage proposed by the previous study. Specimens were fabricated according to KCI-PS101 and ETAG 013. As a result of the static load test, it was verified that the displacement of the wedge and the strand was kept constant when the tensile force of 80% of the nominal strength of the strand was applied. In the load transfer test, it was confirmed that all the specimens satisfied the stabilization formula of KCI-PS101 and ETAG 013. Post-tensioned one-way slab with circular anchorage were fabricated to evaluate the flexural behavior. All specimens exhibited the same flexural behavior and maximum load. However, the specimen with circular anchorage were advantageous than the rectangular anchorage one in terms of crack control of the anchorage zone.

  • Tendocutaneous free flap transfer has been usually used to treat troublesome wounds, which had extensive defect of skin and tendons, since Daniel and Taylor had reported successful free flap transfer in 1973. Among the numerous types of free flap, the dorsalis pedis flap, which could include superficial peroneal nerve, extensor tendon and second metatarsus, was widely used as composite free flap. The authors analysed 13 cases of tendocutaneous free flap transfer from dorsum of the foot which were operated at Korea University Hospital from March 1981 to August 1991. The results were as follows: 1. The average size of these flaps was $53.7cm^2$(mazimum $82cm^2$, minimum $30cm^2)$, the average number and length of tendons were 2.9(maximum, 5, minimum 1), and 9.2cm (maximum 17cm, minimum 5cm). 2. The survival rate of flaps was 100%, and functional results by Dargan's criteria were 4 in excellent, 4 good, 3 fair and 2 poor. 3. The delayed healing on donor site could prevented by the meticulous skin graft and repair of extensor retinaculum. 4. The cases of electrical burn were more worse than the traumatic cases in functional results.

  • Background The temporalis muscle flap transfer with fascia lata augmentation (FLA) is a promising method for smile reconstruction after facial palsy. International literature lacks a detailed anatomical analysis of the temporalis muscle (TPM) combined with fascia lata (FL) augmentation. This study aims to describe the muscle's properties and calculate the length of FL needed to perform the temporalis muscle flap transfer with FLA. Methods Twenty nonembalmed male (m) and female (f) hemifacial cadavers were dissected to investigate the temporalis muscle's anatomy. Results The calculated minimum length of FL needed is 7.03cm (f) and 5.99cm (m). The length of the harvested tendon is 3.16cm/± 1.32cm (f) and 3.18/± 0.73cm (m). The length of the anterior part of the temporalis muscle (aTPM) is 4.16/± 0.80cm (f) and 5.30/± 0.85cm (m). The length of the posterior part (pTPM) is 5.24/± 1.51cm (f) and 6.62/± 1.03cm (m). The length from the most anterior to the most posterior point (aTPMpTPM) is 8.60/± 0.98cm (f) and 10.18/± 0.79cm (m). The length from the most cranial point to the distal tendon (cTPMdT) is 7.90/± 0.43cm (f) and 9.79/± 1.11cm (m). Conclusions This study gives basic information about the temporalis muscle and its anatomy to support existing and future surgical procedures in their performance. The recommended minimum length of FL to perform a temporalis muscle transfer with FLA is 7.03cm for female and 5.99cm for male, and minimum width of 3 cm. We recommend harvesting some extra centimeters to allow adjusting afterward.

  • Anchorage devices play an important role in post-tensioned bridge structures since they must sustain heavy loads in order to permit the transfer of the prestressing force to the structure. In external prestressing, the situation is even more critical since the anchorage mechanisms, with the deviators, are the only links between the structure and the tendons throughout the service life of the structure. The behaviour of anchorage devise may be studied by using the finite element method. To do so, each component of the anchorage must be adequately represented in order to approximate the anchor mechanism as accurately as possible. In particular, the modelling of the jaw/tendon device may be carried out using the real geometry of these two components with an appropriate constitutive contact law or by replacing these components by a single equivalent. This paper presents the numerical study of a mono-strand anchorage device. The results of a comparison between two different representations of the jaw/tendon device, either as two distinct components or as a single equivalent, will be examined. In the double-component setup, the influence of the wedge configuration composing the jaw, and the influence of lubrication of the anchor, will be assessed.

  • Patients with facial paralysis, in whom nerve damage is irreparable or in whom the innervation of the paralyzed musculature cannot be restored by nerve suture, grafting, or cross-face nerve transplantation, should be offered some form of reconstructive static and dynamic aid. Temporalis muscle-fascia unit used as a circumorbital sling and motor unit is a dynamic controlled reconstructive procedure, but it has several disadvantages such as wide surgical exposure, bulky-looking at lateral canthal area, insufficient voluntary control. This is a case report of facial palsy of posttraumatic lagophthalmos of 41-year-old male, which was corrected by temporalis muscle-tendon transfer with plantaris tendon transplantation.

  • Acquired Hallux varus is defined radiographically by a negative metatarsophalangeal angle and clinically by adduction of the hallux on the first metatarsal and most commonly occurs after hallux valgus surgery. It's the prevalence has ranged from 2% to 17%. We report a case of hallux varus resulted from weakening of support of lateral soft tissue and resection of an excessive amount of the metatarsal head during a bunionectomy after initial correction of hallux valgus. We corrected the hallux varus deformity using transfer of extensor hallucis brevis tendon with reconstruction os lateral capsule.
