Purpose: The purpose of this study was to evaluate the clinical results of anterolateral thigh free flap on soft tissue defect following wide excision in malignant soft tissue tumor of lower extremities. Methods: Between February 2005 to April 2010, we followed up 19 cases who were undergoing anterolateral thigh free flap because of soft tissue defect following wide excision of malignant soft tissue tumor in lower extremity, including 9 cases were heel, 5 cases in foot, 3 cases in ankle, 2 cases in knee and leg. We observed that of implanted area's color, peripheral circulation at 3, 5, 7 days after operation and evaluated operating time, amount of hemorrhage, implanted skin necrosis, additional operations, complications. And we also evaluated the oncologic results, including local recurrence, metastasis, and morbidity. Results: Average operation time of wide excision and anterolateral thigh free flap was 7 hour 28 minutes. 18(94.7%) of total 19 cases showed successful engraftment, on the other hand, failure of engraftment due to complete necrosis of flap in 1 case. In 18 cases with successful engraftment, reoperation was performed in 4 cases. Among them, removal of hematoma and engraftment of flap after bleeding control was performed in 3 cases, because of insufficient circulation due to the hematoma. In the remaining 1 case, graft necrosis due to flap infection was checked, and grafted after combination of wound debridement and conservative treatment such as antibiotics therapy, also skin graft was performed at debrided skin defect area. Skin color change was mainly due to congestion with hematoma, flap was not observed global congestion or necrosis except 4 cases which shows partial necrosis on margin that treated with conservative therapy. Conclusions: Anterolateral thigh free flap could be recommended for reconstruction of soft tissue defect following wide excision of malignant soft tissue tumor in lower extremity.

정형외과적 영역에서 족부 족관절 부의의 손상은 흔한 문제이다. 비록 손상들이 생명을 위협하지는 않지만 정확한 진단이나 치료가 지연됐을 시에는 하지의 기능에 장애를 유발 할 수 있으므로 정확한 진단이 장기간의 합병증을 예방 할 수 있다. 초음파는 비용-효과면에서 우수하고 방사선 피폭의 염려가 없으며 연부 조직의 검사에 유용하고 역동적 검사를 시행할 수 있어서 아킬레스건 파열에서 그 유용성이 증가하고 있다. 초음파 영상은 아킬레스건 파열의 진단적 도구이다. 영상의학적 검사 없이 아킬레스건 파열을 진단하기 위해서는 신체 검사와 환자의 병력에 필요하지만 개인 의원에서는 약 20%에서 파열을 놓지는 것으로 알려져 있다. 초음파 영상 하에서 정상적인 섬유 구조의 단절이 아킬레스건 파열의 진단이 되며 실시간으로 족배 굴곡 및 족저 굴곡을 함으로써 단절이 더 확대되는 것을 관찰 할 수 있다. 그리고 수술 후나 보존적인 치료를 시행하는 경우에도 추시 관찰 기간 동안 지속적으로 초음파를 통해 건의 상태를 관찰할 수 있는 유용한 도구이다.

Purpose : The purpose of study was to find out the environmental risk factor that can be easily occurred imbalance muscle activities according to direction for using the ramp during one legged standing. Method : The subjects were 20 normal adults with a mean age of $23.15{\pm}2.14years$ and a Body Mmass Index (BMI) of $22.74{\pm}1.07$. Participants were measured muscle activities on vastus medialis, vastus lateralis, tibialis anterior, peroneus longus during one legged stance at four conditions ramp (down ramp, up ramp, medial ramp, lateral ramp). The statistical analyses were performed using IBM SPSS(Ver. 23) and p-value less than .05 were considered statistically significant for all cases. Result : In this study, the activity of the lower extremity muscle and the ratio of the vastus medial and lateral muscles according to the direction of use of the ramp were investigated. The changes in the muscle activity of the lower limbs along the direction of the ramp were significantly different between the vastus medial muscle and the peroneus longus muscle. Conclusion : For a short time on a ramp or a pedestrian crossing, a clerk in a ramp can move or stand by placing the lower limbs in various directions, but if performed in consideration of the individual's disease characteristics or unstable foot position, It is thought that there will be an effect to prevent on the ankle and knee unstability.

The purpose of this study was to examine the effect of step length on the joint moment. The subjects were 4 undergraduate and graduate students in their 20s with normal legs. The subjects were individually tested by the running timer at the walking speed of 0.67m/s, 134m/s, and 2.46m/s. The step length was regulated to -10% of normal, normal and +10% of normal step length using foot print. The walking performances of each subjects were filmed using a high speed video camera. The raw data were analyzed by LabVIEW Graphical Program and these data were analyzed by ANOVAs and Scheffe. The results of this study were as follows: The maximum dorsiflexion moment of the ankle joint increased as the step length increased only at the fast walking speed. Although there wasn't significant difference shown in the plantar flexion moment, regular pattern in the plantar flexion moment which increased as the step length increased was found. The first maximum extension moment of the knee joint increased only at the normal walking speed, but there appeared no significant difference in the maximum flexion and second extension moment. The maximum extension moment of the hip joint increased at the normal and fast walking speed. Although there wasn't significant difference, regular pattern in flexion moment which increased as the step length increased was found.

인체 해석모델은 주로 인간이 의식적으로 행하는 운동을 중심으로 발전해 왔다. 의식적 운동과 달리 슬개건 반사는 뇌를 거치지 않고 일어난다. 본 연구는 건강한 성인의 슬개건 반사로 인한 대퇴부의 근력과 근활성도를 해석적으로 예측하고자 하였다. 해석 모델은 시상면에서 평면운동을 하고, 앉은 자세에서 상체와 허벅지를 고정시켜 종아리만 진자 운동이 가능하도록 모델링 하였다. 무릎은 레볼루트 조인트로 모델링 하였고, 발목관절은 고정시켜 종아리와 발을 하나의 강체로 가정하였다. 근력은 Mamizuka 의 실험 결과로부터 얻은 운동학 정보를 이용하여 역동역학 해석을 통해 구하였으며, 근활성도는 Hill-type 근육 모델을 이용하여 예측하였다. 해석 결과는 실험결과를 통해 검증되었다.

Latissimus dorsi(LD) muscle is the largest transplantable block of vascularized tissue. Since LD free flap was introduced in 1970's, this flap has been widely used for the reconstruction of large soft tissue defect of the limb. From 1981 to 1996, we had experienced 37 cases of LD free flap. Serratus anterior muscle was combined with LD in three of them whose defects were very large. The average age of the patients was 31 years(range : 4-74 years), and thirty one patients were male. Trauma was cause of the defect in every case. For the recipient sites, the foot and ankle was the most common(22 cases); and the knee and lower leg(11 cases), the elbow and forearm(2 cases), the hand(2 cases) were the next. The duration of follow-up was averaged as 16 months(range: 6 months-12 years). Thirty one cases(84%) out of 37 were successful transplantations. In one case the failure of the flap was due to heart attack and subsequent death of the patient. One failure was caused by sudden violent seizure of the patient who had organic brain damage. Immediate reexploration of the flap was performed in 4 patients, and the flap survived in three of them. There was one necrosis of the grafted split-thickness skin on the survived LD flap. LD free flap was considered as one of the good methods, for the reconstruction of the large soft tissue defect of the limb.

The authors studied 74 patients with cal therapy Kosin University Medical March 1994 through February 1995. The results were, as follows: 1. Average age of the subject patients was 59.3 years old, their age ranged from 20 to 84 years old, and the incidence between male and female was 1:1.24 2. In respect to the economy level the middle class revealed the highest incidence, 40(54%) in 74cases. 3. The cause of injury revealed the highest incidence in hypertension 52 patients(72 %), more than all revealed the highest incidence 23 patients(44 %) in 60th years old. 4. The form of injury revealed the highest incidence in infarction 36 patients(49 %), more then all revealed the highest incidence 13 patients (36 %) in 60th years old. 5. As for the region cerebral artery of infarction patients, middle cerebral artery was the highest region of injury 72 %. 6. As for the physical paralysis side, the left side showed higher incidence 40 patients(54 %) compared to the right side 31 patients (42 %). 7. The period of therapy was 56 days, in average extending from 7 days to II months, nore then all there were the most numerous patients within 3 weeks 28 patients(38 %). 8. The upper side of the upper lims had improved 67 patients(91 %), the lower side 48(65 %). In the cases of the lower limb, the upper side had improved 70(95 %), the lower side 58(78 %). In short, patients had improved more the lower limb than the upper limb, the upper side(elbow and shoulder part) then the lower side(wrist and finger) of the upper limb. In the cases of the lower limb, patients had improved more the upper side (knee and hip part) then the lower side(foot and ankle) 9. In the cases of patients can be walking among subject patients 55(74 %) and patients cannot be walking 19 (26 %), In the cases of patients utilized assistant apparatus 34 (62 %) among self-walking, completely patients can be self-walking 21(28 %).
