이준모,이주홍,Lee, Jun-Mo,Lee, Ju-Hong 대한미세수술학회 1998 Archives of reconstructive microsurgery Vol.7 No.1

전북대학교병원 정형외과에서 1994년 6월부터 1998년 3월까지 하퇴부 원위 1/3 및 족부에 시행하였던 박근 유리조직 이식술 12례에 대하여 최소 6개월부터 최고 4년 9개월까지 추시하여 다음과 같은 결과를 얻었다. 1. 하퇴부 원위 1/3의 손상원인은 개방성 골절에 의한 뼈 및 연부조직노출이 4례(33.3%)였으며, 골절수술후 연부조직 괴사로 인한 2차 뼈 및 내고정물노출이 2례(16.7%)였고, 족부의 손상원인은 압궤손상 5례(41.7%), 골절치료시 발뒤꿈치의 압박괴사 1례(8.3%)였다. 2. 수여혈관은 하퇴부 원위 1/3에서는 전경골 동맥이 4례, 비골동맥과 족배동맥이 각각 1례였으며, 족부의 수여혈관은 족배동맥이 4례, 후 경골동맥이 2례였다. 수여정맥은 2개를 봉합함을 원칙으로 하였으나 하퇴부 원위 1/3에서 총 6례중 3례, 족부에서도 총 6례중 3례에서만 2개의 수여정맥 봉합술이 가능하였다. 3. 총 12례중 11례(91.7%)에서 술후 3주까지 관류(perfusion)가 가능하여 성공하였으며, 피부 이식술은 술 후 평균 22일만에 시행하였고, 재활운동은 술후 평균 32일만에 가능하였다. The gracilis muscle is well suited to small and medium-sized soft tissue defects that cannot be adequately handled by simple rotational flaps and it will conform well to irregular contours, can be split longitudinally at both ends to allow cavities and awkwardly shaped spaces and can be transferred in part or in whole. The gracilis muscle used as a free muscle or musculocutaneous flap is small with a long, narrow contour and its vascular pedicle is a terminal branch of the medial femoral circumflex artery and vein. The aims of soft tissue reconstruction are to cover soft tissue defects, to clear up infection and to prepare for further surgical procedures. Authors have performed 12 gracilis muscle flaps in the lower extremities at Chonbuk National University Hospital from June 1994 through March 1998. The results were as follows. 1. 11 cases of 12(91.7%) were sustained from the crushing injury and secondary complications from the traffic accident. 2. The microsurgical anastomosis of one artery and two veins have performed in 6 cases(50%) of 12 and 11(91.7%) cases of 12 were successful at the third postoperative week and in the final result. 3. Gracilis muscle flap is the infetion-resistant and aesthetically acceptable performed in the lower leg 1/3 and the foot.

저자들은 1992년 7월부터 수부에서 연부 조직이 손상되어 결손된 부위를 신경감각 유리 피부판을 이용하여 재건하여 평균 5년 11개월 추시하였다. 수부에서 적절한 신경감각 유리 피부판은, 절개와 문합시 미세 수술이 가능하도록 충분한 직경과 길이를 가진 혈관이 존재하여야 하며, 피부판에 존재하는 신경은 임계 감수성이 가장 중요하며, 때로는 방어 감수성을 향상시키기 위하여 선택되어져야 한다. 포장 주위 유리 피부판은, 족부의 제 1 협부-공간 피부판과 족지-수질 피부판과 함께 임계 감수성을 향상시키기 위한 중요한 피부판이지만, 수부에서 결손 부위, 그리고 결손 부위의 특수한 상황과 결손 부위가 넓은 경우에는, 2차적으로 방어 감수성의 향상을 위하여 족 배유리 피부판이나 외 상완 피부판 등이 선택되어 질수 있다. 저자들이 치험한 수부 무지의 재건에 이용한 포장 주위 피부판 4례는 임계 감수성이 우수하고, 2점 감별 검사에서 양호한 결과를 보였다. 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.

In this paper, state equation approximation method of multivariable system is studied and minimum order estimation is used in approximation. In this method, state equation of the system is approximated and rational function of the state equation is stablized, therefore controllable, observable system equation is obtained. If the rational function is unstable in approximation procedure, pole of the retional function must be moved, the system to be stable. In this case, to determine coefficients of numerator polynomial squared error method is used.

李俊模 관동대학교 1985 關大論文集 Vol.13 No.3

Two phase Switched-Capacitor networks containing the Norator and Nullator as the active elements can be considered the network to control by means of the total 4 graphs because they are composed of two network-constructions which differ from period and define the graph of current and voltage each other. This paper describes topological formulations of the network functions in Z-domain for this Switched-Capactior networks, and defines Switched-Capacitor common tree in the graph of current and voltage. Denominator polynomial for the response of function is presented by the sum of common tree-branch product to the all Switched-Capacitor common tree. And, describes graphical analysis to the complexity and soulution of network by formulations. As the result, it can be described topologically that the condition for solution of the networks and some kind of eigen complexity of networks.

In the high radial nerve palsy caused by displaced humeral shaft fracture, radial nerve have to be explored in the fracture site. 5 cases of the ruptured radial nerve at the fracture site of the humerus from January 1993 through January 2005 were treated at first by open reduction and internal fixation with plates and screws fixation and then defective radial nerves were grafted with autogenous sural nerves by microsurgical epineurial and or perineurial neurorrhaphy. At average 30.4 months follow-up, 5 cases were recovered from motor and sensory deficit with solid bony union of the humerus shaft fracture. Authors have confirmed that ruptured radial nerve in the humerus shaft fracture grafted with autogenous sural nerve with microsurgical epineurial and or perineurial neurorrhaphy would be expected good motor and sensory recovery.

The bridging of nerve gaps is still one of the major problems in peripheral nerve surgery. To evaluate the role of silicon tube in nerve regeneration, gaps were made by resection of tibial components of sciatic nerves of twenty-five New Zealand rabbits. The gaps were divided into five groups. In group I, the tibial components of sciatic nerves were isolated and the incision immediately closed. In group II, 1-cm segments of the nerve were removed and the silicon tubes filled with autogenous skeletal muscle were sutured in place. In group III, 1-cm segments of the nerve were removed and the silicon tubes filled without muscle were sutured in place. In group IV, 2-cm segments of the nerve were removed and the silicon tubes filled with autogenous skeletal muscle were sutured in place. In group V, 2-cm segments of the nerve were removed and the silicon tubes filled without muscle were sutured in place. At 16th week, the eletromyography, the light and transmission electron microscopy were performed. Nerve conduction study stimulating sciatic nerve proximal to the lesion and recording at gastrocnemius muscle showed that the compound muscle action potentials of the group II with 1 cm nerve defect filled with muscle were higher amplitudes than the group III without muscle. Compound muscle action potentials of the group IV with 2 cm defect filled with muscle showed similar results in comparison with the group V. The light and transmission electron microscpy showed that a good morphological pattern of nerve regeneration in 1 cm gap than 2 cm and in gap with muscle than gap without muscle.

Introduction: To cover the exposed tendons and bones in the foot and hand which need coverage and abundant vascular flow, lateral arm flaps were transferred. Lateral arm flap is a thin and innervated fasciocutaneous flap with a lower lateral cutaneous nerve and posterior radial collateral artery. Materials and methods: From October 1992 through September 2003, we have performed 5 lateral arm flaps for reconstruction of the exposed achilles tendons in 2 cases and the exposed forearm extensors, 2nd to 5th metacarpal bones and scaphoid each 1 case. The causes were traffic accident in 2 cases and machinary injury in 3 cases. Age range was between 31 to 74 (average 50) and all male except 1. Posterior lateral collateral artery and venae comitantes were anastomosed by end to end in 3 cases and vena comitante in 2 cases. Lower lateral cutaneous nerve was anastomosed with a branch of superficial radial nerve in 2 cases. Results: The results were evaluated by survival of the flap, sensory discrimination, cosmesis and comfort in the activities of the daily living. All flaps were survived. Sensory recovery was graded as deep cutaneous pain sensibility in 2 cases. Cosmesis was moderately satisfied and comfort was good except 1 as moderate. Postoperative defatting procedure was done in 1 case and skin abrasion was occurred in 1 case. Conclusion: Lateral arm flap was suitable for coverage of the exposed achilles tendons and exposed forearm extensors, metacarpals and scaphoid in the wrist.
