Spinal osseous tuberculosis, or Pott's spine, although very common in endemic countries, has a lower incidence in very young children. However, the infection has the propensity to cause greater vertebral destruction in this age group, leading to severe structural kyphotic deformity and associated neurologic deficits. We report the case of a 19-month-old child with severe tubercular kyphotic deformity of the upper thoracic spine managed with posterior vertebral column resection (VCR) and nonfusion posterior pedicle screw instrumentation.
This 19-month-old boy presented with 1-month history of spontaneous-onset, progressive, painful rigid kyphotic deformity of the upper back associated with spastic paraparesis with bowel and bladder incontinence. Magnetic resonance imaging showed severe destruction of bodies of D4-D7 vertebrae with cord edema and draping of the spinal cord over the internal gibbus at D4-D7. Surgery was performed with a restricted anterior fusion via single-stage posterior VCR at D4-D7 with nonfusion pedicle screw instrumentation from D1 to D9, with subsequent extension of instrumentation to D10 after 4 months.
Multilevel posterior VCR with a restricted fusion and nonfusion pedicle screw instrumentation beyond the resection site can be safely done in young children (age <3 years) requiring rigid tubercular kyphotic deformity correction. However, these patients require regular follow-up and may need multiple surgeries.
脊柱骨结核,又称波特氏脊柱,虽然在流行地区很常见,但在非常年幼的儿童中发病率较低。然而,这种感染在这个年龄段有更大的椎体破坏倾向,导致严重的结构性后凸畸形和相关的神经功能缺损。我们报告了一例 19 个月大的儿童,患有严重的胸上段结核性后凸畸形,采用后路脊柱全长切除(VCR)和非融合后路椎弓根螺钉内固定治疗。
这名 19 个月大的男孩因 1 个月前突发、进行性、疼痛性僵直性后凸畸形就诊,伴有痉挛性截瘫,伴有大小便失禁。磁共振成像显示 D4-D7 椎体严重破坏,脊髓水肿,脊髓在 D4-D7 处的内脊柱弯曲处呈褶皱状。手术采用单阶段后路 D4-D7 的 VCR 进行有限前路融合,从 D1 到 D9 采用非融合椎弓根螺钉内固定,4 个月后将内固定物延长至 D10。
多节段后路 VCR 联合有限融合和非融合椎弓根螺钉内固定可安全应用于需要矫正僵硬性结核后凸畸形的年幼儿童(年龄<3 岁)。然而,这些患者需要定期随访,可能需要多次手术。
