Despite the recent trend toward the internal fixation of distal radial fractures in older patients, the currently available literature lacks adequate randomized trials examining whether open reduction and internal fixation (ORIF) with a volar locking plate is superior to nonoperative (cast) treatment. The purpose of the present randomized clinical trial was to compare the outcomes of two methods that were used for the treatment of displaced and unstable distal radial fractures in patients sixty-five years of age or older: (1) ORIF with use of a volar locking plate and (2) closed reduction and plaster immobilization (casting).
A prospective randomized study was performed. Seventy-three patients with a displaced and unstable distal radial fracture were randomized to ORIF with a volar locking plate (n = 36) or closed reduction and cast immobilization (n = 37). The outcome was measured on the basis of the Patient-Rated Wrist Evaluation (PRWE) score; the Disabilities of the Arm, Shoulder and Hand (DASH) score; the pain level; the range of wrist motion; the rate of complications; and radiographic measurements including dorsal radial tilt, radial inclination, and ulnar variance.
There were no significant differences between the groups in terms of the range of motion or the level of pain during the entire follow-up period (p > 0.05). Patients in the operative treatment group had lower DASH and PRWE scores, indicating better wrist function, in the early postoperative time period (p < 0.05), but there were no significant differences between the groups at six and twelve months. Grip strength was significantly better at all times in the operative treatment group (p < 0.05). Dorsal radial tilt, radial inclination, and radial shortening were significantly better in the operative treatment group than in the nonoperative treatment group at the time of the latest follow-up (p < 0.05). The number of complications was significantly higher in the operative treatment group (thirteen compared with five, p < 0.05).
At the twelve-month follow-up examination, the range of motion, the level of pain, and the PRWE and DASH scores were not different between the operative and nonoperative treatment groups. Patients in the operative treatment group had better grip strength through the entire time period. Achieving anatomical reconstruction did not convey any improvement in terms of the range of motion or the ability to perform daily living activities in our cohorts.
尽管最近有将桡骨远端骨折患者进行内固定的趋势,但目前的文献缺乏足够的随机试验来比较切开复位内固定(ORIF)与掌侧锁定板和非手术(石膏)治疗是否更优。本随机临床试验的目的是比较两种治疗 65 岁及以上桡骨远端移位不稳定骨折的方法的结果:(1)掌侧锁定板 ORIF 和(2)闭合复位和石膏固定(石膏固定)。
进行了前瞻性随机研究。73 例桡骨远端移位不稳定骨折患者随机分为掌侧锁定板 ORIF 组(n=36)或闭合复位和石膏固定组(n=37)。根据患者腕关节评价(PRWE)评分、上肢功能障碍(DASH)评分、疼痛程度、腕关节活动范围、并发症发生率以及影像学测量(背侧桡骨倾斜、桡骨倾斜和尺骨变异)来评估结果。
在整个随访期间,两组之间的活动范围或疼痛水平没有显著差异(p>0.05)。手术组患者在术后早期的 DASH 和 PRWE 评分较低,表明腕关节功能更好(p<0.05),但在术后 6 个月和 12 个月时两组之间无显著差异。在所有时间点,手术组的握力均明显更好(p<0.05)。在末次随访时,手术组的背侧桡骨倾斜、桡骨倾斜和桡骨缩短明显优于非手术组(p<0.05)。手术组的并发症数量明显高于非手术组(分别为 13 例和 5 例,p<0.05)。
在 12 个月的随访检查中,手术组和非手术组的活动范围、疼痛水平、PRWE 和 DASH 评分没有差异。手术组患者在整个随访期间握力更好。在我们的研究人群中,解剖重建并不能改善活动范围或日常生活活动能力。
