Conservative management of 166 Colles' fractures was associated with a 12% rate of late compression neuropathies (mean follow-up period, 28 months). Compression of the median nerve (8%) was twice as common as ulnar nerve compression (4%). Eighty-five percent of the patients with median nerve compression had malunion with radial collapse with or without other deformities (dorsal angulation/radial displacement). Patients with ulnar nerve compression had either malunion with radial collapse or volar subluxation of the ulnar head in those fractures that healed with dorsal angulation. Patients without nerve complications showed a significantly lower rate of malunions. These results demonstrate that anatomic derangements play a role in the development of late compression neuropathies following Colles' fractures.
166例科莱斯骨折的保守治疗与12%的迟发性压迫性神经病变发生率相关（平均随访期为28个月）。正中神经受压（8%）的发生率是尺神经受压（4%）的两倍。85%的正中神经受压患者存在伴有或不伴有其他畸形（背侧成角/桡侧移位）的桡骨塌陷畸形愈合。尺神经受压的患者在伴有背侧成角愈合的骨折中，要么存在桡骨塌陷畸形愈合，要么存在尺骨头掌侧半脱位。没有神经并发症的患者畸形愈合率显著较低。这些结果表明，解剖结构紊乱在科莱斯骨折后迟发性压迫性神经病变的发生中起作用。
