To determine the incidence of clinically diagnosable post-traumatic syringomyelia (PTS).
A population of 815 consecutive patients with traumatic spinal cord injuries was studied between January 1990 and December 1992.
Reviews of all records, full clinical evaluation, and thorough neurological examination of all patients disclosed 28 patients in whom PTS was confirmed radiologically (3.43%). The incidence of the presenting symptoms, including bladder dysfunction, is described. The level and density of cord lesion was correlated with incidence and it was found that posttraumatic syringomyelia was twice as common in patients with complete injuries than in patients with incomplete injuries. The highest incidence was found in patients with complete dorsal and complete dorsolumbar injuries. The interval between injury and diagnosis ranged from six months to 34 years (mean 8.6 years). This interval was shortest in patients with complete dorsal and incomplete cervical and dorsolumbar cord injuries.
Reduction of the size of the syrinx seen on postoperative MRI correlated well with a satisfactory clinical outcome in 85% of patients.
确定临床可诊断的创伤后脊髓空洞症(PTS)的发病率。
对1990年1月至1992年12月期间连续收治的815例创伤性脊髓损伤患者进行研究。
对所有患者的记录进行回顾、全面临床评估及详细神经学检查后,发现28例患者经影像学证实患有PTS(3.43%)。描述了包括膀胱功能障碍在内的首发症状的发生率。脊髓损伤的水平和密度与发病率相关,发现完全性损伤患者创伤后脊髓空洞症的发生率是不完全性损伤患者的两倍。完全性背侧损伤和完全性背腰段损伤患者的发病率最高。受伤至诊断的间隔时间为6个月至34年(平均8.6年)。完全性背侧损伤、不完全性颈段和背腰段脊髓损伤患者的这一间隔时间最短。
术后MRI上脊髓空洞大小的缩小与85%患者的良好临床结局密切相关。
