In surgical fixation of distal radius fractures with metaphyseal comminution, volar tilt can be restored using an anatomical volar locking plate as a reduction tool. The purpose of our study is to assess the degree of over or under correction of volar tilt that can result with our 'lift' technique and to determine the ratio between theoretical and actual angular correction. We retrospectively reviewed 24 patients who underwent distal radius fracture fixation using this technique and assessed intra-operative radiographs for parameters including pre-'lift' and post-'lift' volar tilt and pre-'lift' plate-shaft angles. The ratio between actual angular correction and theoretical angular correction was calculated. The 'lift' technique is found to be reliable in restoring volar tilt in most fractures. Over- or under-correction does occur due to errors in visual estimation and actual angular correction is generally less than the theoretical angular correction.
在采用解剖型掌侧锁定钢板作为复位工具进行桡骨远端骨折伴干骺端粉碎的手术固定时，掌侧倾斜度可得以恢复。我们研究的目的是评估采用我们的“提拉”技术可能导致的掌侧倾斜过度或矫正不足的程度，并确定理论角度矫正与实际角度矫正之间的比例。我们回顾性分析了24例采用该技术进行桡骨远端骨折固定的患者，并评估术中X线片的参数，包括“提拉”前和“提拉”后的掌侧倾斜度以及“提拉”前钢板-骨干角度。计算实际角度矫正与理论角度矫正之间的比例。结果发现，“提拉”技术在恢复大多数骨折的掌侧倾斜度方面是可靠的。由于视觉估计误差，确实会出现过度矫正或矫正不足的情况，并且实际角度矫正通常小于理论角度矫正。
