Traumatic spondyloptosis of L3 with incomplete neurological involvement: A case report

Intraoperative Closed Reduction of Traumatic Lateraloptosis: Operative Nuances

BACKGROUND AND IMPORTANCE

Traumatic lateral spondyloptosis, or lateraloptosis, is the complete lateral dislocation of the spine. Reduction in these dislocations presents unique challenges, especially in cases of preserved neurological function. Open techniques carry significant risks of cerebrospinal fluid leak and neurological injury. For traditional spondyloptosis, off-table closed techniques have been described but may result in loss of the reduction when the patient is transferred to the operative table. An on-table closed reduction technique has potential advantages over previously described open reduction or off-table techniques for the treatment of lateraloptosis.

CLINICAL PRESENTATION

The authors describe an on-table closed reduction technique for lateraloptosis, presenting an illustrative case in which the technique was applied. This technique is compared with alternative open and off-table reduction techniques described in the literature. The patient had good mechanical and neurological outcomes. At 14 months postoperatively, she is neurologically intact, back to work involving heavy lifting, and has only moderate back pain.

CONCLUSION

On-table closed reduction before open fixation should be considered in cases of lateraloptosis, particularly when there is preserved neurological function.

Irreducible L5/S1 Spondyloptosis in Over 20 Years After Neglected Trauma Treated with Modified Grob's Technique - Case Report

Introduction

Spondyloptosis, characterized by complete slippage of the upper vertebral body relative to the lower vertebral body, is an exceedingly rare condition. Typically, it occurs as a result of a high-energy injury and is promptly managed. It is uncommon for a patient to present to a spinal surgery unit several decades after the initial incident.

Case Report

In this case report, we describe the case of a 62-year-old man who experienced a lumbosacral injury from a fall twenty years prior to seeking treatment. The patient had multiple comorbidities, including obesity and internal medicine conditions. He presented with severe back pain radiating to the lower extremities, accompanied by significant neurogenic chroma and lower extremity weakness. Imaging studies revealed spondyloptosis at the L5/S1 level, along with bony fusion and spinal canal stenosis at the L3/L4 level.

Conclusion

The patient underwent surgical intervention using Grob's direct pediculo-body fixation technique. The postoperative period was uneventful, and over the course of one year of follow-up, the patient experienced a resolution of symptoms and significant improvement in functional capacity.

Traumatic Spondyloptosis: Neurological, Surgical, and Outcome Perspectives in a Tertiary Care Center

Objective To evaluate traumatic spondyloptosis cases for neurological, surgical, and outcome perspectives.

Materials and Methods This retrospective study includes 17 patients of spondyloptosis admitted in our department between August 2016 and January 2020. Each patient was evaluated in terms of demographic profile, clinical presentation, duration of injury, mode of injury, associated injuries, level and type of spondyloptosis, spinal cord status, nociceptive and neuropathic pain severity, severity of injury based on International Standards for Neurological Classification of Spinal Cord Injury (ISNCSI) assessment, surgical approaches, complications, and outcome. Unpaired t- test and Chi-square test were used for statistical analysis. Values with p < 0.05 were considered statistically significant.

Results Fall from height (58.8%) was the most common mode of injury. Most common level of spondyloptosis was T12–L1 (41.1%). Sagittal–plane spondyloptosis (76.5%) were more common than coronal–plane spondyloptosis (23.5%). Most common associated injury was musculoskeletal (64.7%). Neurological status of the patient at presentation (p = 0.0007) was significantly associated with outcome after 3 months of surgery/conservative management. Residual listhesis was present in 53.3% of patients postoperatively. Postoperative nociceptive pain (p = 0.0171) and neuropathic pain (0.0329) were significantly associated with residual listhesis. Duration of injury (p = 0.0228) was also significantly associated with postoperative residual listhesis.

Conclusion Complete reduction of spondyloptosis should be the goal of surgery. Overall prognosis of spinal cord injury (SCI) due to traumatic spondyloptosis is poor.

Traumatic lateral spondyloptosis of L2 with complete neurological deficit: A case report

Traumatic spondyloptosis of the lumbar spine is an uncommon and severe clinical entity, which is defined as complete fracture dislocation and subluxation (>100%) of one vertebral body in the coronal or sagittal plane from its adjacent vertebra. In coronal spondyloptosis the subluxated vertebral bodies lie beside each other, and the condition is lateraloptosis.

CLINICAL CASE

A male patient aged 56 years had multiple injures with complete neurological deficit. Computed tomography(CT) revealed as spondyloptosis, which L2 detached from the rest of the spine, spinal canal stenosis, sagittal imbalance, and angular kyphosis. We performed an en bloc corpectomy and iliac bone combined part of the vertebra body replanted in situ with posterior transpedicular fixation of T12-L4, with the sagittal balance recovered and motor function improved progressively.

CONCLUSION

Traumatic spondyloptosis requires an early resolution by a trained surgical team to ensure sagittal re-alignment for a progressive neurological recovery.
