A 6-year-old, female spayed Pomeranian was presented with acute hind-limb paraplegia with the presence of deep pain perception and urinary incontinence. Myelography showed a Hansen type I herniation of the12th to 13th thoracic intervertebral space (T(12-13)). Articular facets of the T(12-13) and T(13) to first lumbar vertebra (L(1)) were absent. The spinal cord was decompressed using a bilateral T(12-13) modified lateral hemilaminectomy (pediculectomy). The aplastic sites were associated with minimal instability of the vertebral column, and stabilization of the vertebral column was not required. Familiarity with this condition is important, because articular facet aplasia may cause vertebral instability and may require an adjusted surgical approach or vertebral reduction and fusion following decompression.
一只6岁已绝育的雌性博美犬因急性后肢截瘫伴深部痛觉存在及尿失禁前来就诊。脊髓造影显示第12至13胸椎间隙（T(12 - 13)）为汉森I型椎间盘突出。T(12 - 13)以及T(13)至第一腰椎（L(1)）的关节突缺失。采用双侧T(12 - 13)改良外侧半椎板切除术（椎弓根切除术）对脊髓进行减压。发育不全部位与脊柱最小程度的不稳定相关，无需进行脊柱稳定术。熟悉这种情况很重要，因为关节突发育不全可能导致脊柱不稳定，减压后可能需要调整手术方法或进行椎体复位和融合。
