目的通过对内侧楔骨与第2跖骨底间韧带进行形态学相关参数测量,为其重建提供解剖学依据。方法 8只新鲜成年尸体足部标本,测量跗跖背侧及跖侧韧带、Lisfranc韧带的长、宽、面积,Lisfranc韧带附着点距关节面距离及其走行角度。根据测量数据,建立内侧楔骨-第2跖骨底间骨隧道。结果 Lisfranc在3条韧带中形态学数据最大,长、宽、面积分别为(9.11~12.03 mm)、(7.36~10.16 mm)、(92.01~120.01 mm2)。骨隧道进针点在第2跖骨底,距第2跖骨-中间楔骨关节面距离为(8.25~11.22 mm),角度与Lisfranc韧带走行一致,与矢状面呈(39.2°~47.6°),水平面呈(12.5°~19.8°),出针点为Lisfranc韧带在内侧楔骨上的附着点。结论 Lisfranc韧带在3条韧带中最为粗壮,重建通道应按照其附着点和走行角度重建背侧韧带和Lisfranc韧带,而跖侧韧带由于位置较深,受技术所限,此为类解剖重建。
Objective To study the morphological parameters of the medial cuneus and the second metatarsal interosseous ligament, and to provide anatomical basis for the reconstruction. Methods Eight fresh adult cadaver foot specimens were used to measure the length, width and area of Lisfranc ligament, the distance between the ligaments of Lisfranc ligament and articular surface and their walking angles. Based on the measurement data, a medial cuneiform-second metatarsal medullary tunnel was established. Results The Lisfranc had the largest morphological data in three ligaments with length, width and area of (9.11-12.03 mm), (7.36-10.16 mm) and (92.01-120.01 mm2), respectively. The distance from the second metatarsal bone to the second metatarsal-medial cuneiform articular surface was (8.25-11.22 mm), and the angle was consistent with the Lisfranc ligaments, with the sagittal plane (39.2 ° -47.6 °) The horizontal plane (12.5 ° ~ 19.8 °), the needle point for the Lisfranc ligament in the medial cuneiform attachment point. Conclusions The Lisfranc ligament is the most extensive of the three ligaments. The reconstructed channel should reconstruct the dorsal ligament and Lisfranc ligament according to its attachment point and walking angle. However, the ligament of the Lisfranc ligament is limited by the technique due to its deep location, which is anatomic reconstruction.
