Symptomatic adjacent segment disease (ASD) is a common challenge after anterior cervical discectomy and fusion (ACDF). The objective of this study was to compare the biomechanical effects of a second ACDF and laminoplasty for the treatment of ASD after primary ACDF. We developed a finite element (FE) model of the C2-T1 based on computed tomography images. The FE models of revision surgeries of ACDF and laminoplasty were simulated to treat one-level and two-level ASD after primary ACDF. The range of motion (ROM) and intradiscal pressure (IDP) of the adjacent segments, and stress in the cord were analyzed to investigate the biomechanical effects of the second ACDF and laminoplasty. The results indicated that revision surgery of one-level ACDF increased the ROM and IDP at the C2–C3 segment, whereas two-level ACDF significantly increased the ROM and IDP at the C2–C3 and C7-T1 segments. Furthermore, no significant changes in the ROM and IDP of the laminoplasty models were observed. The stress in the cord of the re-laminoplasty model decreased to some extent, which was higher than that of the re-ACDF model. In conclusion, both ACDF and laminoplasty can relieve the high level of stress in the spinal cord caused by ASD after primary ACDF, whereas ACDF can achieve better decompression effect. Revision surgery of the superior ACDF or the superior and inferior ACDF after the primary ACDF increased the ROM and IDP at the adjacent segments, which may be the reason for the high incidence of recurrent ASD after second ACDF.

Abstract Introduction Traumatic brain injury (TBI) is a major cause of mortality around the world. Few advances regarding surgical approaches have been made in the past few years to improve its outcomes. Microsurgical cisternostomy is a well-established technique used in vascular and skull base surgery and recently emerges as a suitable procedure with lesser costs and morbidity when compared with decompressive craniectomy in patients with diffuse TBI. This study aims to describe the technique, indications, and limitations of cisternostomy and to compare it with decompressive craniectomy (DC). Methods A prospective study is being conducted after obtaining approval of the local human ethics research committee. Once the inclusion and exclusion criteria are applied, the patients are submitted to microsurgical cisternostomy, pre and postoperative neurological status and brain computed tomography (CT) evaluation. A detailed review was also performed, which discusses diffuse TBI, DC, and cisternostomy for the treatment of TBI. Results Two patients were submitted to cisternostomy after TBI and the presence of acute subdural hematoma and huge midline shift at admission computed tomography. The surgery was authorized by the family (the informed consent form was signed). Both patients evolved with a good recovery after the procedure, and had a satisfactory control brain CT. No further surgeries were required after the initial cisternostomy. Conclusions Cisternostomy is an adequate technique for the treatment of selected patients affected by diffuse TBI, and it is a proper alternative to DC with lesser costs and morbidity, since a single neurosurgical procedure is performed. A prospective study is being conducted for a better evaluation and these were the initial cases of this new protocol.
