跖跗关节损伤融合板Metatarsal joint injury fusion plate

技术领域technical field

本实用新型涉及医疗器械领域，尤其是一种跖跗关节损伤融合板。The utility model relates to the field of medical equipment, in particular to a fusion plate for tartartarsal joint damage.

背景技术Background technique

Lisfrance关节，即跖跗关节，是前中足之间的关节。即第一、第二、第三跖骨基底部与相应楔骨所形成的关节，以及第四、第五跖骨基底部与骰骨所形成的关节。跖跗关节参与组成足内侧纵弓(第一跖骨与内侧楔骨)、外侧纵弓(第5跖骨与骰骨)和中间横弓(内中外楔骨与骰骨)，对于维持足正常形态起重要作用。Lisfranc关节损伤即跖跗关节骨折-脱位，为一种广义的关节内损伤。The Lisfrance joint, or metatarsal joint, is the joint between the forefoot and midfoot. That is, the joints formed by the bases of the first, second, and third metatarsals and the corresponding cuneiform bones, and the joints formed by the bases of the fourth and fifth metatarsals and the cuboid. The metatarsal joints are involved in the formation of the medial longitudinal arch (the first metatarsal and the medial cuneiform), the lateral longitudinal arch (the fifth metatarsal and the cuboid) and the middle transverse arch (the medial and lateral cuneiform and the cuboid), which play an important role in maintaining the normal shape of the foot. important role. Lisfranc joint injury is a fracture-dislocation of the metatarsal joint, which is a generalized intra-articular injury.

目前临床上对于移位明显的Lisfranc损伤，主张切开复位、坚强内固定。内固定材料主要采用螺丝钉，但螺钉固定强度不够且不稳定，随着术后患者负重下功能锻炼，容易出现复位丢失或螺钉断裂，最终导致手术失败。且经典Lisfranc螺钉需跨关节固定，可进一步加重跖楔关节及楔骨间关节面软骨损伤，增加术后创伤后骨关节炎风险。At present, open reduction and strong internal fixation are advocated clinically for Lisfranc injuries with obvious displacement. Screws are mainly used as internal fixation materials, but the fixation strength of the screws is not strong enough and unstable. With the postoperative functional exercise of the patient under load, it is easy to lose the reduction or the screw breaks, which eventually leads to the failure of the operation. In addition, classic Lisfranc screws need to be fixed across the joint, which can further aggravate the damage of the articular cartilage between the metatarsal wedge joint and the intercuneiular bone, and increase the risk of post-traumatic osteoarthritis after surgery.
