, spinal cord injury (SCI), VA injury, fracture of lateral mass, facet violation, and malposition that required revision or removal. Late screw-related complications included screw loosening, screw pullout, screw breakage, plate/rod breakage, loss of reduction, pseudarthrosis, required revision surgery, and adjacent-segment disease (ASD) requiring surgery. Only complications that were specifically stated as having occurred or not having occurred in the articles were used in the analysis. Complications were not assumed to be absent just because they were not discussed

A djacent -segment degeneration (ASD) after cervical fusion is theorized to occur in part due to a compensatory hypermobility above and below a stiff segment. 40 In multilevel cases, ASD may be a more significant problem, as neighboring segments become more mobile due to the increased construct stiffness. 10 , 26 , 34 , 40 Biomechanical and clinical studies have shown differences in construct stiffness and arthrodesis rates with various multilevel reconstruction techniques; 13 , 46 however, the behavior of the adjacent segments as a function of the

the total 511 patients, 502 (98.24%) presented with back pain, 376 (74.17%) with radiculopathy, 76 (14.87%) with motor weakness, and 32 (6.26%) with pre-operative bowel/bladder dysfunction. An average of 2.04 1.03 spinal levels were fused. Post-operatively, patients experienced a significant improvement in back pain (p<0.0001) and radiculopathy (p<0.0001). Patients with fusions excluding the sacrum (floating fusions) were statistically more likely to develop ASD compared with those with fusion constructs ending at S1 distally (p=0.030), but less likely to develop

A dult spinal deformity (ASD) is a significant source of disability worldwide. 8 , 10 , 12 In the absence of significant or progressive neurological deficits, initial treatment is usually nonoperative, with conversion to surgery for nonresponders; the idea is that successful nonoperative management can spare the risks and pain of more invasive treatment. 9 , 20 The nonoperative approach generally consists of a combination of treatments including bracing, physical therapy and exercise, narcotic and nonnarcotic pain medications, interventional procedures

S urgery for adult spinal deformity (ASD) is a challenging undertaking with significant complexity and technical demand. The surgical treatment of fixed sagittal and/or coronal plane deformities typically involves multilevel arthrodesis with one or more osteotomies for the restoration of global spinopelvic alignment. Three-column resection osteotomies (3COs) are powerful techniques allowing for simultaneous multiplanar deformity correction from a single posterior surgical approach. 21 These techniques involve Grade 3–5 resections and encompass pedicle

O ver the past several decades, surgical treatment options for adult spinal deformity (ASD) have expanded, including both minimally invasive and open techniques. 3 , 12 , 14 , 18 , 27 Determining the most suitable approach in patients should take into account the risks and benefits of each surgical technique. Unfortunately, studies comparing the different operative techniques are lacking. Moreover, outcomes and complications of ASD are largely reported in terms of patient characteristics following traditional open techniques with little published data
