RECOVERY OF LOCOMOTION AFTER DORSAL HEMISECTION OF SPINAL CORD IN ADULT RAT
Chun, Churl-Hong,Song, Ha-Heon,Kim, Jong-Hwan,Shim, Dae-Moo,Kim, Sang-Soo,Ko, Myoung-Chul 圓光大學校 醫科學硏究所 1995 圓光醫科學 Vol.11 No.1
성숙한 12마리의 횐쥐에서 제6번 흉추의 척수 후방 편측손상을 일으킨 후, 족부 직교절선(the kinematics of foot trajectories)의 운동역학을 컴퓨터에 의한 운동 분석기술을 이용하여, 정량적으로 분석한바 놀랍게도 이 동물들에서 운동이 3∼4주 이내에 거의 정상으로 회복되었다. 후방편측 절단후 즉시 횡적 및 수직적 족후부 운동은 극적으로 감소 되었으나, 3주째, 횡적운동의 진폭은 손상전의 수준으로 회복 되었다. 상-하지 협동작용도 초기에는 손상 되었지만 3주내에 정상으로 회복 되었다. 하지 유각기(swing phase)의 기전은 절단후 증가되어 점차로 회복되었으나 완전히 정상으로 회복되지는 못하였다. 족후부 수직운동의 최고 증폭(1.84±0.34)은 후방 편측성 절단후에 0.56±0.21㎝까지 감소 되었다. 이 연구에서 다양하게 분석된 모든 영역의 운동역학은 3∼4주 이내에 손상된 기준으로 회복 되었으나 수직운동의 진폭과 속도는 거의 회복되지 않았다. 따라서 수직 운동의 진폭과 속도가 운동기능을 평가하는 아주 중요한 변수들인 것을 알수있었다. 결론적으로 컴퓨터와 비디오영상을 이용한 운동역학 분석은 신경손상후 운동결손을 발견하기 위한 유용한 방법으로 생각되었다. Using computerized motion analysis techniques, the kinematics of foot trajectories was quantitatively analyzed in twelve rats before and after T6 dorsal spinal cord hemisection. Surprisingly, locomotion in these animals were nearly normal within four weeks. Immediately following dorsal hemisection, horizontal and vertical hindfeet movements were dramatically reduced. By three weeks, the amplitudes of horizontal movement (stride length) returned to pre~lesion levels. Forelimb-hindlimb coordination was also initially disrupted but returned to normal within three weeks. The duration of hindlimb swing phase increased after sectioning, gradually recovered, but never returned to pre-lesion levels. Peak amplitudes (1.84±0.34 ㎝) of hindlimb vertical movement declined to 0.56±0.21 ㎝ after dorsal hemisection. Similarly, peak velocities of hindlimb vertical movement dramatically decreased from 32.688±7.02 ㎝/s to 8.62±3.24 ㎝/s after the hemisection. Although all other kinematic variables analyzed in this study returned to prelesion values within three to four weeks, the amplitude and velocity of vertical movements showed very little recovery, suggesting that these are the most important parameters in assessing locomotor function. This video assisted, computerized kinematic analysis is a sensitive technique for the detection of minor motor deficits following nerve injuries.

새로운 Y-Anatomical Plate 를 이용한 상완골 원위부 골절의 치료
김상수,노성만,전철홍,문은선,고명철 대한골절학회 1996 대한골절학회지 Vol.9 No.4
Objectives; The characteristics of comminuted fractures of the distal end of the humerus in adult are severe comminution of bony fragments. loss of bony continuity and displaced fragments by muscle action. The ideal treatment is to reestabilish a normal elbow-that is to reestablish the articular congruity, the alignment and early motion as soon as possible. But no matter what treatment is used perfect results are seldom obtained. The purpose of this study is to analyze the clinical results of the new Y-Anatomical plate, which has well adaptable and more malleable characteristics for the fracture of the distal humerus. Materials and methods; The fracture types of the distal humerus was 5 supracondylar and 12 intercondylar. which were classification according to the Riseborugh & Radin classification 4 type II, 2 type III and 6 type IV. The patpatients who have been treated by new Y-Anatomical plate from September 1992 to January 1995. Results; Fourteen of the 17 cases(812%) were considered acceptable results for a mean follow-up 26 months study according to the functional motion of the elbow by Cassebaum and criterise by Jupiter J.B.etc. The patient who did exercise the elbow joint within two weeks from post-operation, gathered better results than other patients who did it after four weeks from post-operation. Complications are nonunion ankylosing elbow and mettal failure. Conclusion; In de study reported here, new Y-Anatomical plate was sufficiently obtained the anatomical w4ction with stable fixation, so it would allow early motion of the elbow joint to be possible and decrease the complication compared to Tri-radiate plates. Also the nest important' indicator of end result was the starting time of physiotherapy.
