Description
技术领域 technical field
本发明涉及一种接骨板，主要用于腓骨远端骨折（外踝部位的骨折、Danis-Weber分型：A/B/C型）、下胫腓联合损伤等。 The invention relates to a bone plate, which is mainly used for fractures of the distal end of the fibula (fractures at the lateral malleolus, Danis-Weber classification: type A/B/C), syndesmosis injuries and the like.
背景技术 Background technique
作为下肢最为主要的负重关节之一的踝部，其发生损伤是临床中最为常见的，占到关节内骨折的首位，而单踝骨折又以外踝骨折也就是腓骨远端骨折最为常见，约占踝关节损伤的57.6%。而随着高能量损伤的发生，多数复杂的踝关节损伤都伴有外踝骨折。因此，腓骨远端骨折的治疗逐渐倍受临床骨科医师及社会广泛关注。腓骨远端不仅与胫骨远端构成下胫腓关节，同时与距骨构成距腓关节，同时在其后下方有腓骨长短肌腱沟，在其末端有距腓前后韧带、跟腓韧带的起点，腓骨远端不稳定骨折不仅破坏了外踝的骨性结构的完整，同时影响韧带起止点的连续性。研究表明步态姿势中20％的向上力量由外踝吸收，外踝的长度和对位是踝关节整复中最重要的环节，其次者是对内踝及下胫腓韧带的修复。因此，腓骨远端骨折的解剖重建与踝关节稳定性的恢复极具相关性。踝部骨折的治疗要求解部复位恢复外踝正常外翻角及长度等解剖结构，以适应距骨前下宽、后上窄形态，并且要求达到有效、坚强固定，为早期活动提供稳定性，以防止创伤性关节炎及退变性关节炎的发生，而外踝骨折的处理对踝关节的稳定性起关键作用。 As one of the most important weight-bearing joints of the lower limbs, the ankle is the most common injury in clinical practice, accounting for the first place in the intra-articular fracture, and the single malleolus fracture is the most common fracture of the lateral malleolus, which is the fracture of the distal end of the fibula, accounting for about 57.6% of ankle injuries. With the occurrence of high-energy injuries, most complex ankle injuries are accompanied by fractures of the lateral malleolus. Therefore, the treatment of distal fibular fractures has gradually attracted widespread attention from clinical orthopedic surgeons and society. The distal end of the fibula not only forms the inferior tibiofibular joint with the distal end of the tibia, but also forms the talofibular joint with the talus. At the same time, there is a tendon groove of the long and short fibular tendon below it. The unstable fracture of the end not only destroys the integrity of the bony structure of the lateral malleolus, but also affects the continuity of the starting and ending points of the ligament. Studies have shown that 20% of the upward force in gait posture is absorbed by the lateral malleolus. The length and alignment of the lateral malleolus are the most important links in the rehabilitation of the ankle joint, followed by the repair of the medial malleolus and the inferior tibiofibular ligament. Therefore, anatomic reconstruction of distal fibula fractures is highly relevant to restoration of ankle stability. The treatment of ankle fractures requires partial reduction to restore the anatomical structure such as the normal valgus angle and length of the lateral malleolus to adapt to the shape of the talus, which is wide anteriorly and inferiorly and posteriorly superiorly narrow, and requires effective and strong fixation to provide stability for early activities to prevent The occurrence of traumatic arthritis and degenerative arthritis, and the treatment of lateral malleolus fractures play a key role in the stability of the ankle joint.
目前，治疗外踝骨折的固定装置及方式较多。传统克氏针、张力带以及单纯螺钉等固定均因缺乏对骨折远端的坚强固定而不能完全满足临床要求。近年来出现的普通1/3管型、重建板虽然有一定的强度，但并不符合外踝的解剖特点而必须塑形，尤其针对下胫腓联合以远的Weber A、B型骨折或骨质疏松性、粉碎性骨折，由于并非专门设计用于外踝，使得骨折远部的螺钉固定数量有限而难以满足坚强有效固定的要求。而近年来三叶草型普通接骨板虽在远端固定的螺钉数量有所增加，但因远端接触面过大，需软组织彻底剥离而损伤较大，且普通螺钉抗把持能力较弱，仍难以满足粉碎骨折或骨质疏松性骨折的力学要求。现有的专门用于腓骨远端的解剖型接骨板或普通锁定接骨板，虽达到解剖学要求，但其螺纹孔设计均为同向固定，并且骨折远端实际能够固定的螺钉数量也非常有限，且螺钉均由外侧向内侧关节内植入，临床中时常当心螺钉进入关节内，使得操作中螺钉长度上均要小于实际测量值，使得临床应用及操作上带来不便，且影响固定的有效强度而导致易于松动，往往因此需制动而造成患者不能过早功能锻炼，尤其是针对Weber A、B型骨折或骨质疏松性、粉碎性骨折的固定一直较为棘手。对此，不论是骨科医师还是患者都迫切希望能够针对外踝骨折创造一款固定把持力更强、临床操作更加简便、软组织张力影响小的专用外踝解剖接骨板，以提高治疗效果和改善患者不得已而长时间制动的痛苦。 At present, there are many fixation devices and methods for treating lateral malleolus fractures. Traditional Kirschner wires, tension bands, and simple screws cannot fully meet the clinical requirements due to the lack of strong fixation of the distal end of the fracture. Although the ordinary 1/3 tube shape and reconstruction plates that have appeared in recent years have certain strength, they do not conform to the anatomical characteristics of the lateral malleolus and must be shaped, especially for Weber A and B fractures or bone fractures far from the inferior tibiofibular syndesmosis. For loose and comminuted fractures, since they are not specially designed for use on the lateral malleolus, the number of screw fixations in the distal part of the fracture is limited, making it difficult to meet the requirements for strong and effective fixation. In recent years, although the number of screws fixed at the distal end of the clover-shaped common bone plate has increased, the contact surface of the distal end is too large, which requires a complete stripping of the soft tissue, resulting in greater damage, and the anti-grip ability of ordinary screws is weak, which is still difficult to meet. Mechanical requirements for comminuted or osteoporotic fractures. Although the existing anatomical bone plate or common locking bone plate specially used for the distal end of the fibula meets the anatomical requirements, the threaded holes are all designed to fix in the same direction, and the number of screws that can actually fix the distal end of the fracture is also very limited , and the screws are all implanted into the joint from the outside to the inside. In clinical practice, the screws are often inserted into the joint, so that the length of the screws during operation is smaller than the actual measured value, which makes clinical application and operation inconvenient, and affects the effectiveness of fixation. It is easy to loose due to the high strength, and often needs to be braked so that the patient cannot exercise prematurely, especially for Weber A and B fractures or osteoporotic and comminuted fractures. It has always been difficult to fix. In this regard, both orthopedic surgeons and patients are eager to create a special lateral malleolus anatomical bone plate with stronger fixation and holding force, easier clinical operation, and less influence of soft tissue tension for lateral malleolus fractures, so as to improve the treatment effect and improve the patient's last resort. Painful braking for long periods of time.

所述的主板由三段板体一体构成，且第二板体、第三板体侧面相对第一板体侧面朝向相反的方向弯曲，这样主板与腓骨的连接更加符合解剖特点并且对皮肤软组织的张力更小，其上的锁定孔设计的螺纹使得锁定螺钉减少进入关节内的风险，通过锁定螺钉连接后非常牢固，各个方向上都不容易产生移位；第三板体位置通过设置两个翼板与外踝部分之间形成多方向的固定，连接强度高，尤其适合用于下胫腓联合以下的腓骨远端骨折的固定。所述的第二锁定孔、第三锁定孔和第四锁定孔靠近两个翼板的位置，通过不同角度的锁定螺钉进行固定之后，加之配合两个翼板，不但其上的螺钉方向避开进入关节内，而且更能保证接骨板对外踝骨折固定起到三维立体多向稳定固定，有利于患者更快地康复如初，保证治疗效果。 The main board is composed of three sections of boards, and the sides of the second board and the third board are bent in the opposite direction relative to the side of the first board, so that the connection between the main board and the fibula is more in line with the anatomical characteristics and can protect the skin and soft tissues. The tension is smaller, and the thread design of the locking hole on it reduces the risk of the locking screw entering the joint, and the connection through the locking screw is very firm, and it is not easy to shift in all directions; the position of the third plate body is set by setting two wings Multidirectional fixation is formed between the plate and the lateral malleolus, and the connection strength is high, which is especially suitable for the fixation of distal fibula fractures below the tibiofibular syndesmosis. The second locking hole, the third locking hole and the fourth locking hole are close to the positions of the two wing plates, and after being fixed by locking screws at different angles, coupled with the two wing plates, not only the direction of the screws on them is avoided It enters the joint, and it can better ensure that the bone plate can achieve three-dimensional and multi-directional stable fixation of the lateral malleolus fracture, which is conducive to the faster recovery of the patient and ensures the treatment effect.
