“…Pelvis inclination ranged from À21 to 5 in the supine and standing positions, respectively, and there was a strong correlation between the two positions (R ¼ 0.88). Another study [34] was conducted to evaluate the differences between the two positions using lateral x-ray images. Twenty-three patients were imaged and the results showed no significant differences in lumbar lordosis (P ¼ .06), sacral inclination (P ¼ 1.00).…”

“…It should be noted that a number of studies [27][28][29][30]34,44] have reported on the use of lateral pelvis images and their utility in the management of hip pathologies. The purpose of our review was to compare likely variations between erect and supine AP pelvic imaging and not to evaluate the utility of a lateral projection.…”

Aim: Pelvic radiography is used for the identification of hip joint changes, including pathologies such as osteoarthritis. Several studies have recommended that the position for this radiological procedure should be standing, not supine, to reflect the functional appearances of the hip joint. The aim of this review was to evaluate pelvis radiography positioning with respect to the image appearances and information provided for clinical decision-making. Aside from this, potential recommendations to the radiographic technique for an erect pelvis projection will be considered. Method: A literature search was performed using databases/abstract systems (ScienceDirect, Web of Science, PubMed, and MEDLINE). Only articles written in English were included. Results: Twenty-five articles were identified. Findings from the review describe the effect of repositioning from supine to erect on a series of specific hip measurements. These include pelvic tilt, joint space width, and the acetabular component.

“…These are then used to measure sagittal plane intervertebral motion. A myriad of patient positioning protocols have been tested or deployed (11,58,70,(97)(98)(99)(100)(101)(102)(103)(104)(105) extension with a mechanically controlled device provokes more translation than the "standard of care" exionextension they analyzed. The list goes on, and the research continues while the "standard of care" remains unstandardized.…”

Background Lumbar spinal instability is very commonly discussed in research studies and is routinely used in clinical practice to make treatment decisions. That practice must be reconciled with expert consensus in the peer-reviewed literature: there is currently no validated diagnostic test for spinal instability. Some treatments for instability can have serious complications, so correct diagnosis is important. Biomechanically rational and clinically effective diagnostic tests for instability are needed, where instability is defined as incompetence of the intervertebral motion restraints forming the passive part of the motion control system.Methods This study critically examines and identifies deficiencies in previously employed metrics and criteria for diagnosing spinal instability. New metrics are described that account for the deficiencies. The new metrics were retrospectively applied to 7621 lumbar spine flexion-extension studies to document the prevalence of abnormalities in different patient populations.Results Traditional measurements, such as intervertebral rotation or translation, may fail to find abnormalities in intervertebral motion due to factors such as inconsistent patient effort and radiographic magnification. The proposed biomechanically grounded metrics for lumbar spine sagittal plane shear and vertical instability appear more adept at finding abnormalities in patient populations where abnormalities might be expected and not in patients where instability would not be expected.Discussion New approaches to detecting abnormal sagittal plane intervertebral motion may lead to enhanced and standardized diagnosis of lumbar spine instability. Further clinical research is imperative to validate the efficacy of these metrics in diagnosis and treatment algorithms.

“…Several studies have suggested that recumbent radiographs are inferior to standing films for lumbar spondylolisthesis, with a significant difference in percentage slip between standing and supine imaging. 15,16 Furthermore, a study by Gardner et al 17 demonstrated that supine MRI often underestimates the extent of rotary subluxation. The author's suggestion that it is beneficial to include long spine or full-body AP radiographs as a standard component of preoperative imaging for deformity patients is therefore a good one and may be critical to operative planning.…”
