[Abstract]:Objective: (1) to observe the anatomical characteristics of the posterior interosseous ligament (interosseous talocalcaneal ligament, ITCL) and analyze its clinical significance. (2) to study the biomechanical characteristics and clinical significance of the anterior and posterior interosseous ligaments of the calcaneus.
Materials and methods: (1) 10% formaldehyde fixed adult normal cadaver foot specimens 20 pairs, without gender, side, to the posterior interosseous ligament, the shape of the posterior fasciculus. After disconnecting the ankle joint, cut off the lateral and lateral ligaments of the outer side of the lower joint and the medial ligament of the medial side of the medial surface and the medial ligament. Bone ligament - calcaneus specimens were dissected to separate the structure of the tarsal sinus and reveal the three roots and the lateral margin of the intercalcaneal ligament under the extensor. The talus was sawed along the posterior edge of the tarsal canal and the posterior part of the tarsal canal was removed. The posterior fasciculus of the ligaments of the calcaneus was revealed, and the shape was observed and the vernier caliper (0.02) was observed. Mm) gross measurement. After the resection of the posterior fasciculus, the posterior fasciculus of the interosseous ligament was exposed and the anterior fascicles of the interosseous ligament were exposed and observed. The length of the ligament length was two between the middle points of the attachment, and the width and thickness were measured at the point of the ligament length. (2) 12 sides of adult fresh lower extremities were isolated. The ankle joint was broken and the soft tissues such as the skin, muscle, and tendon in the calcaneus nodules were removed from the lower part of the lower part of the joint. The medial and lateral malleolus and the middle posterior part of the calcaneus were revealed. The talus and the posterior part of the calcaneus were covered with polymethacrylate methyl acrylate. In this experiment, the front was 0 degrees, the lateral was 90, the rear was 180, and the medial was 27. 0 degrees. The specimen is fixed on the universal biomechanics machine. The specimen is rotated at 30 degrees, and the mechanical load is loaded along the foot parallel to the foot for three times (the pressure of 60N is applied to the specimen at the speed of 5N/ seconds). Then the 6 sides of the specimen are cut off the front bundle and the other 6 sides are cut off and the experimental steps are repeated.
Results: (1) the intercalcaneal ligaments are short and toughened, located in the tarsal canal between the anterior and posterior joints of the heel. The ligament and the tarsal sinus on the coronal plane mean an average of 45 degrees, and the direction from the posterior oblique forward is through the tarsal canal. The ligament consists of the front and the latter two. The anterior bundle fiber is the posterior part of the calcaneus groove, the front of the tarsal canal wall, attached to the front of the tarsal canal. The anterior calcaneal surface and the middle distance of the articular surface, the lateral and the cervical ligaments, go forward and go forward out of the talus neck and attached to the top wall of the canal. The anterior bundle is closer to the anterior side than the posterior bundle. The lateral view is more inclined than the posterior bundle. The anterior bundle is rhombic or broad stripe. The posterior bundle fibers attach to the posterior of the calcaneus to the front of the articular surface and tarsus. The posterior lateral part of the canal, ascending or posterior, stops at the front of the talus posterior articular surface, the top wall of the tarsal canal, the base of the talus sulcus. The posterior bundle fiber is located below the articular motor axis and adjacent to the medial root of the extension of the extensor. The ligament is closely attached to the anterior part of the joint capsule to form the local thickening of the joint capsule. The posterior bundle is relative to the anterior bundle. It is closer to the latter. The lateral view shows that the ligament is close to the foot plane and is slightly biased. The shape can be trapezoid or broad "V". (2) the amount of the talar displacement and the amount of the talus displacement is related to the experimental direction. The increase of the talar displacement is 30, 90, 120 and 150 degrees after cutting off the anterior bundle. The size of the talus is significantly greater than that in the other directions (P0.01). The talus mainly increases the displacement of the anterolateral, and the amount of the increase of the talus displacement in the direction of 180, 300, and 330 is obviously larger than that in the other directions (P0.01), and the increase of the talus is mainly the forward side.
Conclusion: (1) broad hypertrophy of the interosseous ligaments is located in the middle of the subtalar joint and under the motor axis of the joint. The anatomical indication of the ligaments in this experiment may be mainly to maintain close contact with the intercalcaneal ligament, and to prevent the internal and outward movements of the subcalcaneal joints. In addition, the posterior bundle of intercalcaneal ligaments is relative to the anterior bundle fiber. Closer to the latter, shorter and larger than the anterior bundle, it is more important to limit the talus varus. (2) before and after the interosseous ligaments, the functions of the bundles are focused on their anatomy and the function of the posterior fasciculus is more important. The posterior bundle should be the main treatment for the reconstruction of the ligaments and should be rebuilt according to the walking of the posterior bundle.
