The purpose of this study was to evaluate the changes in alignment during the course of treatment for extra-articular distal radius fracture and the relationship of initial and intermediate radiographs, with the final radiograph taken at fracture union. A cohort of 96 consecutive patients who were conservatively managed for extra-articular distal radius fracture in an 18-month period was undertaken. The radiographs analysed were taken at prereduction, postreduction, a week later and at fracture union. The radiological parameters analysed were radial tilt, radial length, radial inclination, dorsal comminution and ulnar styloid fracture. There was a significant change in radiographic alignment between initial and immediate postreduction radiographs, and between postreduction 1 week later radiographs (p < 0.05), but the number of patients in the 1 week later and fracture union groups remained similar (p > 0.05). All patients with poor radiological outcome had ulnar styloid fractures. This was also associated with dorsal comminution in 86% of patients. Patients with satisfactory radiological outcome had ulnar styloid fracture and comminution in 34% and 43% of patients respectively. The final radiological outcome was not found to be influenced by initial unsatisfactory alignment of radial tilt, radial length and radial inclination individually or in combination. We suggest that two clinic visits after initial reduction of the fracture should be sufficient to manage such injuries; the first visit 1 week after manipulation to detect unacceptable displacement and if found satisfactory, the last visit at fracture union for final review, advice and referral to physiotherapy.
本研究的目的是评估桡骨远端关节外骨折治疗过程中的对线变化,以及骨折复位前、复位中期的X线片与骨折愈合时最终X线片之间的关系。我们纳入了一组在18个月内接受保守治疗的96例连续桡骨远端关节外骨折患者。分析的X线片包括复位前、复位后、复位后1周及骨折愈合时的片子。分析的放射学参数包括桡骨倾斜度、桡骨长度、桡骨倾角、背侧粉碎及尺骨茎突骨折情况。复位前与复位后即刻的X线片之间,以及复位后1周与复位后即刻的X线片之间,在放射学对线方面均有显著变化(p<0.05),但复位后1周组与骨折愈合组的患者数量仍相似(p>0.05)。所有放射学结果不佳的患者均有尺骨茎突骨折。这在86%的患者中还伴有背侧粉碎。放射学结果满意的患者中,分别有34%和43%的患者存在尺骨茎突骨折及粉碎。最终放射学结果未发现受桡骨倾斜度、桡骨长度及桡骨倾角初始对线不佳单独或联合影响。我们建议,骨折初次复位后进行两次门诊就诊应足以处理此类损伤;第一次就诊在手法复位后1周,以检测不可接受的移位,若结果满意,最后一次就诊在骨折愈合时进行最终评估、提供建议并转诊至物理治疗。
