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

I ndividuals who have adult spinal deformity (ASD) typically experience pain and disability. 2 , 14 , 26 , 28 , 29 The pain typically affects the back, legs, or both, and its etiology is multifactorial. 26 , 28 , 29 Over the last decade, most research into ASD has focused on patient-reported outcomes and on general measures of health status and function, such as the Oswestry Disability Index (ODI), the 36-Item Short Form Health Survey (SF-36), and the Scoliosis Research Society 22-question Questionnaire (SRS-22). However, pain is the primary concern for

A dult spinal deformity (ASD) is a pathological condition defined as spinal malalignment in the axial, coronal, or sagittal plane and is derivative of congenital, iatrogenic, degenerative, or idiopathic etiology. 30 The restoration of sagittal alignment, as established by the sagittal vertical axis (SVA; target < 5 cm) and pelvic tilt (PT; target < 20°) on sagittal radiography, is important in surgical deformity correction. 6 , 21 , 22 Although coronal plane correction also has clinical relevance, sagittal corrections appear to have greater importance, 5

Background/Introduction: Pseudarthrosis after adult spinal deformity (ASD) surgery may result in instrumentation failure and need for revision. However, the correlation between fusion grade with or without rod fractures and HRQoL is not known. We assessed the association between HRQoL, fusion grade, and rod fracture with and without revision surgery. Materials/Methods: A prospective, multi-center ASD database with 2 year followup data was reviewed. Fusion grade was determined on plain films using published criteria; Grade III or IV at one or more segments was

Antifibrinolytic agents such as tranexamic acid (TXA) have been used in an attempt to reduce intraoperative blood loss. However, there is no universally accepted dosing protocol for TXA in spine surgery. Moreover, there are very few reports in the literature regarding high

T he morbidity of adult spinal deformity (ASD) surgery has been well proven through several large multiinstitutional studies. 6 , 9 , 14 Although these operations carry inherent risk, the benefits of such interventions have been shown as well, provided that the tenets of the surgical goals have been met. 2 , 10 , 11 Given these conditions, substantial enthusiasm has been demonstrated for minimally invasive surgery (MIS) options. 5 , 7 , 18 , 22 Various technical methods have been developed to achieve these ends, including 1) leveraging alternate access routes
