Spinal cord injuries due to penetrating wounds are not uncommon. The management of these injuries remains controversial especially with regard to the effect of laminectomy on the neurological outcome.
Between 1980 and 1989, 64 patients injured by bullets and shell fragments to the spinal cord were reviewed. There were 58 males and 6 females: 24 injuries (37.5%) involved the cervical spine, 37 (57.8%) the dorsal spine, and 3 (4.7%) the lumbar spine. One group (group I) consisted of 47 patients (73.4%) who had immediate and complete sensorimotor loss of function. Another group (group II) contained 13 patients (20.3%) who presented with incomplete and non-progressive spinal cord deficit. One patient (1.6%) (group III) had progressive spinal cord deficit. Three patients (4.7%) (group IV) had injuries to the cauda equina.
The results were analyzed using a chi-squared test when possible. In group I, 20 patients (42.5%) underwent laminectomy with no recovery, and 27 (57.5%) were treated conservatively, with 1 patient (3.7%) achieving marked improvement (p > 0.05). In group II, 3 patients (23.1%) underwent laminectomy with the 3 (100%) improved, and 10 patients (76.9%) were treated conservatively, with 8 (80%) recovering (p > 0.05).
Our data in groups I and II agree with previously published literature that shows no significant advantage of performing laminectomies following penetrating spinal cord injuries. Moreover, group I patients had a poor prognosis whether laminectomy was done or not, and group II patients had a good prognosis whether laminectomy was done or not.
穿透伤导致的脊髓损伤并不罕见。这些损伤的处理仍存在争议,尤其是椎板切除术对神经功能预后的影响。
回顾1980年至1989年间64例因子弹和弹片导致脊髓损伤的患者。其中男性58例,女性6例:24例(37.5%)损伤累及颈椎,37例(57.8%)累及胸椎,3例(4.7%)累及腰椎。一组(I组)由47例患者(73.4%)组成,这些患者立即出现完全性感觉运动功能丧失。另一组(II组)包含13例患者(20.3%),他们表现为不完全性且非进行性脊髓功能缺损。1例患者(1.6%)(III组)有进行性脊髓功能缺损。3例患者(4.7%)(IV组)有马尾神经损伤。
尽可能使用卡方检验分析结果。在I组中,20例患者(42.5%)接受了椎板切除术但无恢复,27例(57.5%)接受保守治疗,1例患者(3.7%)有明显改善(p>0.05)。在II组中,3例患者(23.1%)接受了椎板切除术且3例(100%)均有改善,10例患者(76.9%)接受保守治疗,8例(80%)恢复(p>0.05)。
我们I组和II组的数据与先前发表的文献一致,即穿透性脊髓损伤后进行椎板切除术没有显著优势。此外,I组患者无论是否进行椎板切除术预后都很差,II组患者无论是否进行椎板切除术预后都很好。
