The aim of this study was to compare the time to radiological bony union of simple A-type fractures of the forearm, treated with either a locking compression plate (LCP) or a dynamic compression plate (DCP). For each fracture, the relation between the use of compression and radiological healing time was studied. Nine fractures were treated with LCP and 10 fractures with DC plates. The mean time to definite radiological bony union in the LCP group was 33 weeks and in the DCP group 22 weeks. Compression was used in 7 fractures in the DCP group and in 3 fractures in the LCP group. The compressed fractures, irrespective of the type of plate, healed 10 weeks faster than the non-compressed fractures. Time to definite radiological bony union of simple A-type fractures does not depend on the type of plate used, but on the application of axial or interfragmentary compression.
本研究的目的是比较采用锁定加压钢板（LCP）或动力加压钢板（DCP）治疗的单纯A型前臂骨折达到影像学骨愈合的时间。针对每例骨折，研究了加压使用情况与影像学愈合时间之间的关系。9例骨折采用LCP治疗，10例骨折采用DCP治疗。LCP组达到明确影像学骨愈合的平均时间为33周，DCP组为22周。DCP组7例骨折使用了加压，LCP组3例骨折使用了加压。无论使用何种类型的钢板，加压的骨折比未加压的骨折愈合快10周。单纯A型骨折达到明确影像学骨愈合的时间不取决于所使用钢板的类型，而是取决于轴向或骨折块间加压的应用。
