    Notes: Abstract Chylous leakage is an unusual complication following anterior spinal surgery. This leakage can occur as a result of traumatic injury to the thoracic duct, the cisterna chyli, or the retroperitoneal lymphatic vessels. The authors present case reports of three patients who underwent anterior spinal surgical procedures in advertently complicated by an injury to the lymphatic system. All patients were managed nonoperatively with tube drainage and hyperalimentation and had uneventful recoveries.

    Notes: Abstract This retrospective study evaluated a single surgeon's series of patients treated by multilevel cervical disc excision (two or three levels), allograft tricortical iliac crest arthrodesis, and anterior instrumentation. The objective of this retrospective study was to compare fusion success and clinical outcome between multilevel Smith-Robinson interbody grafting and tricortical iliac strut graft reconstruction, both supplemented with anterior instrumentation in the cervical spine. The incidence of nonunion for cervical discectomy and fusion varies widely depending on the number of disc levels involved, type of bone graft used, and whether the anterior grafting is supplemented with instrumentation. An alternative to multilevel interbody fusion is corpectomy and strut grafting, in which the incidence of nonunion has been reported to be 27% with autograft and 41% with allograft. Sixty-four consecutive patients who underwent allograft tricortical iliac crest reconstruction and anterior cervical plating were studied. The average follow-up was 39 months. There were 38 patients in the discectomy and interbody grafting group and 26 patients in the corpectomy and strut graft reconstruction group. Pseudoarthrosis occurred in 42% of the anterior cervical interbody fusion patients and 31% of the corpectomy patients. Nonunion in two-level interbody fusions occurred in 36% of the patients as compared to 10% for patients with one-level corpectomies; while 54% of patients with three-level interbody fusions and 44% of patients with two-level corpectomies were noted to have pseudoarthrosis. Higher percentages of nonunion were noted in multilevel interbody grafting than in corpectomy with strut grafting and when more vertebral levels were involved. These radiographic and clinical findings underscore the shortcomings of multilevel anterior cervical allograft reconstruction with plating. Corpectomy may be the preferred method when multiple disc levels are fused. In addition, anterior corpectomy affords decompression of significant osteophytes in a safer and quicker manner. In retrospective studies, there is a need for long-term follow-up before accurate statements can be made about the study population.

    Notes: Abstract Various conditions such as fracture, dislocation, tumor, or infection adversely affect the vertebral body and lead to instability. Restoration of a stable anterior column is essential for normal spinal biomechanics. Various biological and mechanical spacers have been used to reconstruct the anterior column after corpectomy. In this retrospective review, the authors evaluated clinical charts and radiographs of 13 patients receiving titanium surgical mesh (TSM)-bone graft composite to reconstruct the anterior spinal column in the thoracic or lumbar region. The objective of this review was to evaluate the stability and efficacy of the TSM-bone graft composite in the anterior spine after a complete or partial corpectomy. Sixteen patients with involvement of the thoracic or lumbar vertebral column after trauma, tumor, or infection underwent partial or complete corpectomy. In all patients the anterior defect was reconstructed using a TSM-bone graft composite. Three patients died within 12 months postoperatively due to primary malignant process. Thirteen of 16 patient charts and radiographs were evaluated for anterior fusion status, settling of the TSM-bone graft composite, and hardware failure. No pseudoarthroses were noted. Evidence of solid anterior fusion was noted in all patients. The average settling of the TSM-bone graft construct was 3 mm. All patients presenting with only pain and no neurological symptoms (n = 9) experienced early pain relief. For patients presenting with neurological symptoms (n = 4), the recovery was complete in three and partial in one. No patient was made neurologically worse, and there were no vascular injuries intra- or postoperatively. The study suggests that TSM-bone graft composite offers excellent biomechanical stability in the immediate postoperative period, permitting progressive maturation of the fusion mass.
