A total of 118 consecutive patients with a fracture of the distal radius were treated with a volar locking plate; 50 patients had no ulnar styloid fracture, 41 had a basal ulnar styloid fracture, and 27 had a fracture of the tip of the ulnar styloid. There were no significant differences in radiological and clinical results among the three groups. The outcome was good and was independent of the presence of a fracture of the ulnar styloid. A total of five patients (4.2%) had persistent ulnar-sided wrist pain at final follow-up. Nonunion of the ulnar styloid fracture did not necessarily lead to ulnar wrist pain. Patients with persistent ulnar pain had a higher mean initial ulnar variance and increased post-operative loss of ulnar variance. The presence of an associated ulnar styloid fracture of the ulnar styloid does not adversely affect the outcome in patients with a fracture of the distal radius treated by volar plating.
共有118例桡骨远端骨折患者接受了掌侧锁定钢板治疗；50例患者无尺骨茎突骨折，41例有尺骨茎突基底骨折，27例有尺骨茎突尖端骨折。三组之间的影像学和临床结果无显著差异。结果良好，且与尺骨茎突骨折的存在无关。共有5例患者（4.2%）在最终随访时仍有尺侧腕部疼痛。尺骨茎突骨折不愈合不一定会导致尺侧腕部疼痛。持续尺侧疼痛的患者初始尺侧平均变异度较高，术后尺侧变异度丢失增加。伴有尺骨茎突骨折并不对接受掌侧钢板固定治疗的桡骨远端骨折患者的预后产生不利影响。
