骨折是指骨结构的连续性完全或部分断裂。老年人由于骨质较为疏松，在没有外力作用，也就是在日常生活活动的情况下也极易发生骨折。而对于青少年或者是成年人来说，在平常一般不会发生骨折，只有在骨头受到极大的外力作用的情况下，如：撞击、高处跌落、车祸等，都会多骨头造成很大的伤害，从而产生骨折。而在骨折中，关节骨折和胫骨平台的骨折是最为常见的，随着现在医疗技术的发展，CT诊断的应用越来越广泛，对于骨折中的胫骨平台的骨折的诊断率也随着这些技术的发展而不断提高。其中又属胫骨平台后外侧骨折的占比率最高，一般的保守治疗中，患者后期的外侧关节面高度无法完全恢复，导致在治疗后形成创伤性关节炎，因此在现如今的治疗中，手术治疗的应用越来越广泛。但是采用手术治疗时通常在手术时的切口较大，并且很容易对病人腿上的神经、血管等造成严重的损伤，并且其康复的时间较长，对于膝关节后外侧的支撑固定的稳定效果弱，极易发生二次损伤，增加患者痛苦并且延长治疗时间。并且其钢板固定时螺钉的旋入角度固定，只能相对于钢板垂直旋入，在一些发生裂损的情况下治疗较为麻烦。 A fracture is a complete or partial break in the continuity of the bone structure. Due to the relatively loose bone quality of the elderly, fractures are also extremely prone to occur in the absence of external force, that is, in the case of activities of daily living. For teenagers or adults, fractures do not usually occur, and only when the bones are subjected to a huge external force, such as: impact, falling from a high place, car accident, etc., will cause great damage to the bones. , resulting in a fracture. In fractures, joint fractures and tibial plateau fractures are the most common. With the development of medical technology, CT diagnosis is more and more widely used, and the diagnostic rate of tibial plateau fractures in fractures is also increasing with these technologies. development and continuous improvement. Among them, posterolateral fractures of the tibial plateau account for the highest proportion. In general conservative treatment, the height of the lateral articular surface cannot be fully recovered in the later stage of the patient, resulting in the formation of traumatic arthritis after treatment. Therefore, in the current treatment, surgical treatment application is becoming more and more widespread. However, when surgical treatment is used, the incision is usually larger, and it is easy to cause serious damage to the nerves and blood vessels on the patient's leg, and the recovery time is longer, which has a stable effect on the support and fixation of the posterolateral knee joint. Weak, prone to secondary damage, increased patient suffering and prolonged treatment time. And when its steel plate is fixed, the screw-in angle of the screw is fixed, and can only be screwed in vertically relative to the steel plate, and the treatment is relatively troublesome in some cases of crack damage.
