Internal radiocarpal distraction plating is a versatile tool in the treatment of distal radius fractures that are not amenable to nonoperative treatment or operative fixation with standard volar or dorsal implants. Internal distraction plates may also be indicated in the setting of polytrauma or osteopenic bone. The plate functions as an internal fixator, using ligamentotaxis to restore length and alignment while providing relative stability for bony healing. The plate can be fixed to either the second or the third metacarpal, and anatomic and biomechanical studies have assessed the strengths and weaknesses of each strategy. This operative fixation technique leads to acceptable radiographic results and functional outcomes. Following fracture union, the plate is removed, and wrist range of motion is resumed.
桡骨内辐射状撑开固定是治疗不适合非手术治疗或标准掌侧或背侧植入物手术固定的桡骨远端骨折的多功能工具。在多发伤或骨质疏松性骨的情况下,内部撑开板也可能是指征。该板作为内部固定器,利用韧带牵引术恢复长度和对线,同时为骨愈合提供相对稳定性。该板可固定在第二或第三掌骨上,解剖学和生物力学研究评估了每种策略的优缺点。这种手术固定技术可获得可接受的影像学结果和功能结果。骨折愈合后,取出钢板,恢复腕关节活动度。
