Hybrid construction (HC) may be an ideal surgical strategy than noncontinuous total disc replacement (TDR) and noncontinuous anterior cervical discectomy and fusion (ACDF) in the treatment of noncontinuous cervical spondylopathy. However, there is still no consensus on the segmental selection for ACDF or TDR in HC. The study aims to analyse the effects of different segment selection of TDR and ACDF on cervical biomechanical characteristics after HC surgery.

Biomechanical effects of hybrid constructions in the treatment of noncontinuous cervical spondylopathy: a finite element analysis.

 The treatment of skip-level cervical degenerative disease (CDD) with no degenerative changes observed in the intervening segment (IS) is complicated. This research aims to provide a reference basis for selecting treatment approaches for noncontiguous CDD.  To establish accurate finite element models (FEMs), this study included computed tomography (CT) data from 21 patients with CDD (10 males and 11 females) for modeling. The study primarily discusses four cross-segment surgical approaches: upper (C3/4) anterior cervical discectomy and fusion (ACDF) and lower (C5/6) cervical disc arthroplasty (CDA), FA model; upper CDA (C3/4) and lower ACDF (C5/6), AF model; upper ACDF (C3/4) and lower ACDF (C5/6), FF model; upper CDA (C3/4) and lower CDA (C5/6), AA model. An initial axial load of 73.6 N was applied at the motion center using the follower load technique. A moment of 1.0 Nm was applied at the center of the C2 vertebra to simulate the overall motion of the model. The statistical analysis was conducted using STATA version 14.0. Statistical significance was defined as a  value less than 0.05.  The AA group had significantly greater ROM in flexion and axial rotation in other segments compared to the FA group ( < 0.05). The FA group consistently exhibited higher average intervertebral disc pressure in C2/3 during all motions compared to the AF group ( < 0.001); however, the FA group displayed lower average intervertebral disc pressure in C6/7 during all motions ( < 0.05). The AA group had lower facet joint contact stresses during extension in all segments compared to the AF group ( < 0.05). The FA group exhibited significantly higher facet joint contact stresses during extension in C2/3 ( < 0.001) and C6/7 ( < 0.001) compared to the AF group.  The use of skip-level CDA is recommended for the treatment of non-contiguous CDD. The FA construct shows superior biomechanical performance compared to the AF construct.

Segment selection for fusion and artificial disc replacement in the hybrid surgical treatment of noncontiguous cervical spondylosis: a finite element analysis.

This study aims to analyze the diagnosis and treatment conditions of polytrauma patients with spinal injuries, to clarify the site of the first surgical intervention, the timing of the surgery, and factors influencing prognosis.

Analysis of factors influencing the surgical treatment outcomes of spinal injuries in polytrauma patients.

This study aims to explore the connections between risk factors and clinical outcomes in octogenarian patients diagnosed with adult degenerative scoliosis (ADS). A total of 394 patients participated in this study, with 206 individuals in the younger group and 188 in the octogenarian group. We meticulously gathered patient demographics, including basic information, comorbidities, radiographic data, clinical scoring systems, and details on medical and surgical complications as well as revision surgeries. Univariable linear regression analysis revealed positive correlations between age and several postoperative outcomes: Sagittal vertical axis (SVA) (B = -0.572, P = 0.001), Oswestry Disability Index (ODI) (B = 0.145, P < 0.001), and Japanese Orthopaedic Association (JOA) score (B = 0.035, P < 0.001). Additionally, a positive relationship was observed between age and both proximal junctional kyphosis (PJK) (B = 0.055, P = 0.039) and internal fixation loosening (B = 0.253, P < 0.001). Receiver operator characteristic (ROC) curve analysis indicated that the age threshold values for predicting PJK and internal fixation loosening were 71.5 and 79.5, respectively. In octogenarian patients with ADS, the cost associated with spinal deformity surgery is accompanied by a greater incidence of surgical complications. Compared to younger patients, surgical intervention tends to be more effective at enhancing objective motor functions while having a lesser impact on the subjective experiences of octogenarian patients.
