“…Incorporation of a supine lateral radiograph in place of extension radiograph can improve the understanding of segmental mobility when evaluating degenerative spondylolisthesis. [ 1 ] Landi suggested that DXR in flexion and extension performed in recumbent position (RDXR). With the patient lying along his side, it can reduces the augmented muscular tone of the paravertebral muscles in patients with low back pain or sciatic pain and might discover hypermovements hidden by antalgic contractions when investigated with DXR obtained in standing position.…”

Objective: Lumbar segmental instability (LSI) is due to a pathologic movement of the vertebral body on the vertebra below and often causes clinical symptoms. The study was to achieve the research progress of diagnosing methodology for lumbar segmental instability and help clinicians make treatment choices. Methods: The data for this study were collected from the MEDLINE, Springer, Web of Science, PubMed, EMBASE, the Cochrane Central Register of Controlled Trials, Evidence Based Medicine Reviews, VIP, and CNKI. The search terms were integrated as follows: “(∗lumbar instability∗ OR ∗lumbar spondylolisthesis∗) and (∗image∗ or ∗diagnosis∗)”. Studies without clear radiographic instable criteria, case reports, letter, and basic research were excluded. Result: In total, 39 articles published met our inclusion criteria. The various modalities were used to diagnosis LSI in these studies included radiographs, facet joint degeneration and physical examination tests. Conclusion: Overall, there have been a variety of researches to develop the diagnosing methodology for LSI, and many have been successful, although no consensus has been reached yet. However, it is believed that the diagnosis of LSI will become easier and more accurate in the near future.

“…Spondylolisthetic parameters: 1) slip degree (SD), measured as the slipped distance of L4 divided by the length of L5 upper endplate; 2) anterior disc height (ADH), measured as the distance from L5 anterior upper corner to L4 lower endplate; 3) posterior disc height (PDH), measured as the distance from L4 posterior lower corner to L5 upper endplate; 4) slip angle (SA), de ned as the angle between L4 lower endplate and L5 upper endplate; 5) slip angle motion (SAM), de ned as the absolute value of subtraction between slip angles in radiograph (standing) and T2-weighted MR image (supine); and 6) slip degree motion (SDM), de ned as the absolute value of subtraction between slip degrees in radiograph and T2weighted MR image. [15,16] Spino-pelvic parameters: 1) lumbar lordosis (LL), measured as the angle subtended between tangents of T12 lower endplate and S1 sacral endplate; 2) sacral slope (SS), measured as the angle subtended between tangent of S1 endplate and horizontal line; 3) pelvic tilt (PT), de ned as the angle between the vertical and a line from the center of the femoral heads to the midpoint of the sacral endplate; 4) pelvic incidence (PI), de ned as the angle subtended between a line perpendicular to the sacral plate at its midpoint and a line connecting this point to the axis of the femoral heads; 5) thoracic kyphosis (TK), de ned as the angle between the perpendicular of T5 upper endplate and the perpendicular of T12 lower endplate; and 6) sagittal vertical axis (SVA), de ned as the distance from C7 plumb line to superior corner of the sacral endplate ( Figure 2).

Background: Degenerative lumbar spondylolisthesis (DLS) has been a common disease that make increasing patients suffer from different degrees of low back pain and radicular symptoms. At present, the incidence of kyphosis in DLS and the differences in spinal sagittal morphology between kyphotic and non-kyphotic DLS still remain unclear. Our study aimed to determine the incidence of kyphosis in DLS, explore the characteristics of spondylolisthetic and spino-pelvic sagittal parameters, and evaluate the impact of kyphosis on the life quality of patients with DLS.Methods/Design: All 108 patients with L4/5 low-grade DLS were enrolled and divided into kyphotic and non-kyphotic group. 2 spine surgeons who have certain clinical experience were selected to measure the spondylolisthetic and spino-pelvic parameters, as well as visual analogue scale (VAS) and Oswestry disability index (ODI). Differences between the 2 groups and characteristics of measurements were analyzed.Results: The inter-observer agreement of all parameters between the 2 spine surgeons were excellent with each ICC > 0.75. Kyphotic group had higher SA, SD, SDM, SAM, PDH, PT and SVA, and lower ADH, SS and LL than those in non-kyphotic group (p < 0.01). There was no significant difference in PI and TK between the two groups (p > 0.05).Conclusion: The incidence of kyphotic spondylolisthesis in patients with L4/5 low-grade DLS is 16.7%. Compared with those in non-kyphotic group, patients with kyphosis show inferior results of spondylolisthetic parameters, more severe loss of LL, more obvious pelvic retroversion and trunk anteversion, which indicates worse spino-pelvic sagittal balance. In addition, their quality of life was significantly lower than that of patients in non-kyphotic group.
