Abstract

Traumatic lumbosacral joint dislocation (TLSJD) without L7 vertebral body fracture is a rare injury in dogs. This report describes clinical presentation, therapy and outcome in 3 dogs. Three crossbreed dogs with non-ambulatory paraparesis and lumbar pain were referred. Radiographs confirmed TLSJD and dorso-ventral displacement (DVD) was measured pre and postoperatively. Case 1 was treated by percutaneous transilial pinning. Cases 2 and 3 were treated by internal fixation with pins and PMMA. Within 72h after surgery all dogs were able to stand and walk, and faecal incontinence resolved. To the author’s knowledge this is the first description of a case series of TLSJD in the dog. The biomechanics of TLSJD in animals have not been investigated. It is likely that a single trauma severely hyper-extends L7-S1 causing disruption of the supra and inter-spinous ligaments with simultaneous shear and compression forces that cause ventral slipping of the sacrum. Pins and PMMA compared to percutaneous transilial pinning, provided more strength and stability. In conclusion, TLSJD requires appropriate surgical reduction and stabilization to allow fibrous healing of the L7-S1 junction, resulting in satisfactory neurological recovery
3只犬外伤性腰骶关节脱位:临床表现、诊断、治疗及短期随访
无L7椎体骨折的外伤性腰骶关节脱位(TLSJD)是犬中罕见的损伤。本文描述了3只狗的临床表现、治疗和结果。本文介绍了3只非活动截瘫和腰痛的杂交犬。x线片证实了TLSJD,并在术前和术后测量了背腹位移(DVD)。病例1采用经皮经睫状体钉扎术。病例2、3采用针内固定加PMMA治疗。术后72小时内,所有犬均能站立行走,大便失禁消失。据作者所知,这是犬类TLSJD系列病例的首次描述。TLSJD在动物体内的生物力学尚未研究。单一创伤可能导致L7-S1严重过伸,导致棘上韧带和棘间韧带断裂,同时产生剪切和压缩力,导致骶骨腹侧滑动。针和PMMA相比,经皮经尿道针,提供了更多的强度和稳定性。总之,TLSJD需要适当的手术复位和稳定,以允许L7-S1连接处的纤维愈合,从而获得令人满意的神经恢复
