【摘要】： 一、研究背景和目的: 前交叉韌帶(Anterior Cruciate Ligament, ACL)是人體中最為復(fù)雜的結(jié)構(gòu)之一,其損傷的治療越來越引起人們的重視。但隨著近年來對(duì)ACL在膝關(guān)節(jié)運(yùn)動(dòng)生物力學(xué)中功能研究的進(jìn)一步深入,人們逐漸認(rèn)識(shí)到,目前ACL臨床重建技術(shù)已無法滿足日益增長(zhǎng)的對(duì)恢復(fù)ACL精妙生物力學(xué)功能的要求。只有更加仿真地模擬生理ACL解剖結(jié)構(gòu)和力學(xué)特性進(jìn)行重建,才能夠最大程度地重現(xiàn)生理ACL的生物力學(xué)功能,最終達(dá)到滿意的臨床效果。 多纖維束重建是目前開展較為廣泛的研究之一,雙束重建已在解剖結(jié)構(gòu)和運(yùn)動(dòng)控制功能上更加接近生理。但由于多個(gè)纖維束起止點(diǎn)的最佳組合方式和對(duì)應(yīng)纖維束在運(yùn)動(dòng)中的張力協(xié)調(diào)更為復(fù)雜,給多纖維束重建帶來了較大困難,目前此方面開展的研究尚不足以闡明其關(guān)系。本研究擬從ACL起止點(diǎn)的解剖和定位方法入手,采用全新設(shè)計(jì)的國(guó)人交叉韌帶張力測(cè)試系統(tǒng)對(duì)ACL的4纖維束動(dòng)態(tài)應(yīng)力進(jìn)行測(cè)量研究,進(jìn)一步了解ACL起止點(diǎn)與其多纖維束動(dòng)態(tài)生物力學(xué)之間的相關(guān)性,為臨床重建ACL提供更詳細(xì)的解剖和力學(xué)數(shù)據(jù)。 二、研究方法: 1.國(guó)人膝關(guān)節(jié)ACL起止點(diǎn)形態(tài)和定位的解剖與放射學(xué)對(duì)比研究 (1)32側(cè)正常國(guó)人膝關(guān)節(jié)解剖數(shù)據(jù)測(cè)量:參照Tiburtius法制作標(biāo)本后測(cè)量ACL股、脛骨側(cè)止點(diǎn)的基本解剖數(shù)據(jù)(印跡中心、徑向偏角、最大長(zhǎng)徑、最大橫徑)。 (2)12側(cè)正常國(guó)人膝關(guān)節(jié)標(biāo)本放射學(xué)測(cè)量:使用金屬標(biāo)記物定位ACL股、脛骨側(cè)止點(diǎn),在CR片上將股骨側(cè)骨性標(biāo)記組成4對(duì),分別為:①股骨干遠(yuǎn)端解剖軸(A)與平行的雙后髁切線(B);②雙前髁切線(C)與雙后髁切線(B);③Blumensaat’s線(D)和與之平行的雙股骨髁遠(yuǎn)端切線(E);④與股骨干遠(yuǎn)端解剖軸垂直的雙髁遠(yuǎn)端切線(F)和與股骨干遠(yuǎn)端解剖軸垂直的雙后髁切線(G)。脛骨側(cè)使用平臺(tái)內(nèi)外緣和前后緣作為骨性標(biāo)記。使用X-Caliper測(cè)量ACL止點(diǎn)印跡與以上骨性標(biāo)記的距離,計(jì)算其在各組骨性標(biāo)記間距離的比值。
[Abstract]:I. background and purpose of the study:. Anterior cruciate ligament (ACL) is one of the most complex structures in human body, and the treatment of ACL injury has attracted more and more attention. However, with the further research on the function of ACL in knee motion biomechanics in recent years, People have come to realize that at present, the clinical reconstruction technology of ACL can not meet the increasing requirement of restoring the delicate biomechanical function of ACL. Only by simulating the anatomical structure and mechanical properties of physiological ACL more simulatively, In order to reproduce the biomechanical function of physiological ACL to the maximum extent, the satisfactory clinical effect can be achieved. Multi-fiber bundle reconstruction is one of the most extensive researches. The double bundle reconstruction has been more close to physiology in anatomical structure and motion control function. However, the optimal combination of the starting and ending points of multiple fiber bundles and the coordination of the tension of the corresponding fiber bundles in motion are more complicated. It has brought great difficulties to the reconstruction of multi-fiber bundles, but the current research in this field is not enough to clarify its relationship. This study will begin with the anatomical and localization methods of the starting and ending points of ACL. A new Chinese cruciate ligament tension testing system was used to measure the dynamic stress of 4 fiber bundles of ACL. The correlation between the starting and ending points of ACL and the dynamic biomechanics of ACL was further understood. Provide more detailed anatomical and mechanical data for clinical reconstruction of ACL. Second, research methods:. 1. Comparative anatomical and radiologic study on the morphology and location of the starting and ending point of ACL in Chinese knee joint. Measurement of anatomical data of the knee joint of 32 normal Chinese: the basic anatomical data of ACL strands and tibia were measured with reference to the Tiburtius method (imprinted center, radial deviation angle, maximum length diameter, maximum transverse diameter). Radiometric measurement of 12 normal Chinese knee joint specimens: using metal markers to locate the ACL strands and tibia lateral insertion points, 4 pairs of femur bone markers were made up of CR films. The anatomic axis of the distal femoral shaft (A1) and the parallel double posterior condylar tangent (BJ) and the double posterior condylar tangent (C) and the double posterior condylar triangulation (BJ 3 Blumensaatos) and the parallel double femur condylar distal condyle (Ef4) perpendicular to the distal double condyle of the distal femoral shaft. The tibial side was marked by the external and outer margins of the platform and the anterior and posterior edges of the platform. X-Caliper was used to measure the distance between the ACL insertion and the above bone markers. The ratio of the distance between the bone markers in each group was calculated.
