The purpose of this article is to define the relations of the symphysis pubis and capsular tissues to the adductor and rectus abdominis soft-tissue attachments on cadaver dissection and correlate with MRI of the anterior pelvis.
Seventeen cadavers (8 males and 9 females; mean age, 80 years) were dissected bilaterally. Rectus abdominis and adductor muscles were traced to the pubis and further attachments to the pubic symphysis were defined. Ten asymptomatic (mean age, 17; age range, 16.5-29 years) male athletes underwent 1.5-T MRI of the anterior pelvis with two surface microcoils (each 42 mm in diameter). An axial T2-weighted turbo spin-echo (TSE) sequence (TR/TE, 2,609/106; voxel size, 0.4 mm) was obtained. Axial and sagittal 3D T1-weighted fast-field echo (FFE) sequences (25/4.9; voxel size, 0.3 mm) were obtained. Sequences were repeated incorporating fat suppression and i.v. gadolinium. The relation of the symphysis pubis, disk, and capsular tissues to the insertions of the rectus abdominis, adductor muscles, and gracilis were independently evaluated by two experienced radiologists blinded to all clinical details.
In all 17 cadaver specimens, the adductor longus and rectus abdominis attached to the capsule and disk of the symphysis pubis, whereas the adductor brevis had an attachment to the capsule in seven specimens and the gracilis in one. All adductor tendons attached to the pubis. In all 10 athletes, the adductor longus and rectus abdominis bilaterally contributed to the capsular tissues and disk. This was only the case for the adductor brevis in four athletes. No other tendons involved the capsular tissues.
Cadaver and MRI findings show an intimate relationship between the adductor longus; rectus abdominis; and symphyseal cartilage, disk, and capsular tissues.
本文旨在通过尸体解剖明确耻骨联合及关节囊组织与内收肌和腹直肌软组织附着点之间的关系，并与骨盆前部的磁共振成像（MRI）结果进行对比。
对17具尸体（8例男性和9例女性；平均年龄80岁）进行双侧解剖。追踪腹直肌和内收肌至耻骨，并明确其与耻骨联合的进一步附着情况。10名无症状男性运动员（平均年龄17岁；年龄范围16.5 - 29岁）接受了使用两个表面微线圈（每个直径42毫米）的骨盆前部1.5-T MRI检查。获得了轴位T2加权快速自旋回波（TSE）序列（TR/TE，2609/106；体素大小0.4毫米）。还获得了轴位和矢状位3D T1加权快速场回波（FFE）序列（25/4.9；体素大小0.3毫米）。重复进行序列检查，包括脂肪抑制和静脉注射钆对比剂。两名对所有临床细节不知情的经验丰富的放射科医生独立评估耻骨联合、椎间盘和关节囊组织与腹直肌、内收肌和股薄肌附着点之间的关系。
在所有17个尸体标本中，长收肌和腹直肌附着于耻骨联合的关节囊和椎间盘，而短收肌在7个标本中附着于关节囊，在1个标本中附着于股薄肌。所有内收肌腱均附着于耻骨。在所有10名运动员中，长收肌和腹直肌双侧均与关节囊组织和椎间盘有关。只有4名运动员的短收肌是这种情况。没有其他肌腱与关节囊组织有关。
尸体解剖和MRI结果显示长收肌、腹直肌与耻骨联合软骨、椎间盘和关节囊组织之间存在密切关系。
