PURPOSE The purpose was to clarify the load-bearing functions of the fibers of the femoral anterior cruciate ligament (ACL) attachment in resisting tibial anterior drawer and rotation. METHODS A sequential cutting study was performed on 8 fresh-frozen human knees. The femoral attachment of the ACL was divided into a central area that had dense fibers(More)
PURPOSE The purpose of this study is to evaluate the morphology of the mid-substance and fan-like extension fibres of ACL during knee motion with reference to the femoral attachment. METHODS This study used six fresh-frozen cadaveric knees and 22 embalmed cadaveric knees to macroscopically evaluate morphological changes in the ACL attachment during knee(More)
In order to investigate the effect of the ectoderm on the pattern of mesodermal components in the chick leg, the ectoderm of the early limb bud was dorsoventrally reversed with respect to the mesoderm. The dorsoventral pattern was assessed by examination of the muscles, skeleton and epidermal differentiation. The earlier the stage at which the recombinants(More)
INTRODUCTION Pancreatic cancer invasion via neural routes (perineural invasion) has been studied extensively, but detailed research on the morphology of innervation of the pancreas related to perineural invasion is scarce. AIMS To clarify the morphology of neural distribution in the human pancreas. METHODOLOGY The pancreas and surrounding structures(More)
BACKGROUND It is generally believed that the supraspinatus is the most commonly involved tendon in rotator cuff tears. Clinically, however, atrophy of the infraspinatus muscle is frequently observed in patients with even small to medium-size rotator cuff tears. This fact cannot be fully explained by our current understanding of the anatomical insertions of(More)
Interactions between Wnts, Fgfs and Tbx genes are involved in limb initiation and the same gene families have been implicated in mammary gland development. Here we explore how these genes act together in mammary gland initiation. We compared expression of Tbx3, the gene associated with the human condition ulnar-mammary syndrome, expression of the gene(More)
For an accurate assessment of jaw movement, it is crucial to understand the comprehensive formation of the masticatory muscles with special reference to the relationship to the disc of the temporomandibular joint. Detailed dissection was performed on 26 head halves of 14 Japanese cadavers in order to obtain precise anatomical information of the positional(More)
BACKGROUND Double-bundle anterior cruciate ligament (ACL) reconstruction has several potential advantages over single-bundle reconstruction with hamstring tendons. However, there are still controversies regarding tunnel placement in tibial and femoral attachments. HYPOTHESIS The macroscopically normal ACL consists of small bundles about 1 mm in diameter.(More)
BACKGROUND Detailed anatomical information of the infraspinatus is important in order to discuss muscle function. The aim of this study was to investigate the morphology, histology and innervation of the infraspinatus muscle, in order to construct an anatomical basis for diagnoses and operative procedures. MATERIALS AND METHODS We used 51 shoulders(More)
PURPOSE The aim of this study was to investigate the attachment of the medial patellofemoral ligament (MPFL) using cadaver specimens and establish an anatomic basis for optimal MPFL reconstruction to achieve better patella stability. METHODS Sixteen knees of eight cadavers were used in this study. The relationship of the MPFL with quadriceps muscles was(More)
