Summary: The study showed that Mobidisc implantation led to improvement in lumbar lordosis (LL) and segmental lordosis (SL) at the treated level, with an increase in both anterior and posterior disc height. However, disc height at the adjacent level decreased.

Summary: Based on the summary of research evidence, this review found that changes in spinopelvic alignment may occur after total hip arthroplasty (THA) and may improve with time. Pelvic tilt was the most frequently measured parameter and was associated with increased risk of THA dislocation. Furthermore, there was no significant change observed in lumbar spine scoliosis in patients with bilateral hip osteoarthritis after THA. In addition, the study found that postoperative changes in spinopelvic alignment parameters were not correlated with improvement in low back pain (LBP).

Summary: The relationship between acetabular dysplasia and spino-pelvic alignment was explored in this study. The results showed no significant association between acetabular dysplasia and spino-pelvic parameters, but a higher pelvic incidence may be a factor associated with acetabular dysplasia.

Summary: This study aims to propose a quantitative definition of hip flexion contracture and analyze its impact on sagittal alignment. The results demonstrate that patients with hip flexion contracture exhibit a specific pattern of spinopelvic alignment and head position. Although the surgical outcome improves, hip mobility is not always restored.

Summary: This study used MRI-based muscle measurement technique to compare the muscle composition of patients with normal and malalignment in terms of sagittal spinal and spinopelvic alignment. Significant differences were found in muscle composition between the two groups, and ROC analysis indicated that FIPPM could predict sagittal spinal malalignment with moderate sensitivity and specificity.

Summary: This study aims to identify patients with sagittal spinopelvic imbalance or spinal stiffness using radiographic markers on standing anteroposterior (AP) pelvis radiographs. The study found that the overlap of the sacrococcygeal junction and pubic symphysis and the presence of lumbosacral hardware were associated with an increased risk of combined sagittal imbalance and stiffness.

Summary: A study was conducted to investigate the effect of pelvic tilt on the risk of dislocation after total hip arthroplasty (THA) using a novel radiographic measurement. Patients who experienced dislocation had more posterior pelvic tilt and smaller PSCD compared to controls. Patients with a PSCD <0 had 9-fold odds of dislocation, highlighting the importance of evaluating pelvic tilt and PSCD for identifying increased risk of dislocation.

Summary: More female participants experienced sacroiliac joint pain than male participants. The study showed that higher pelvic incidence and sacral slope values were related to sacroiliac joint pain among low back pain patients.

Summary: The study compares sagittal alignment between patients with degenerative lumbar spondylolisthesis (DLS) who reached or missed the minimal clinically important difference (MCID) for clinical outcomes following lumbar fusion surgery (LFS) and identifies radiographic predictors associated with MCID achievement in DLS patients. The study findings demonstrate that DLS patients who reached MCID following LFS showed improved post-op spinopelvic alignment. Higher triangle SLL, higher triangle SS, and higher post-op SS were identified as critical parameters associated with MCID achievement in patients with DLS.

Summary: An analysis of revision lumbar fusions found that surgeries performed by a different surgeon may achieve better functional outcomes compared to those performed by the same surgeon. The study also identified factors such as patient age, length of time since last surgery, and surgical approach that can impact the likelihood of achieving clinically important differences in outcomes.

Summary: This study investigated spinal alignment parameters in the largest multi-ethnic cohort of asymptomatic adult volunteers. The results showed that spinal alignment was related to age and sex, with differences in the angles of spinal lordosis and kyphosis in different regions. These findings are important for predicting the ideal spinal alignment of individuals.

Summary: In this study, it was found that 46% of patients had spinopelvic pathology driven by one or more risk factors, with 13% exhibiting adverse spinopelvic mobility. The presence of multiple risk factors was positively correlated with the risk of adverse spinopelvic mobility, with 57% of patients with all three risk factors experiencing this complication.

Summary: The manual measurement technique of spinal sagittal alignment on X-rays is susceptible to rater-dependent variability. This study found that different raters had different significance levels when evaluating the pre- to postoperative change of lumbar lordosis in patients receiving lumbar spondylodesis. Therefore, it is important to describe the evaluation process and validate the consistency of results through multiple raters in every publication.

Summary: This study examined the influence of global balance on spinopelvic motion in patients undergoing THA. It found that lumbosacral and hip motions played major roles in global alignment postural change, with paradoxical motion posing a rare but dangerous clinical condition in THA. The findings suggest that paradoxical motion may increase the risk of hip impingement and instability compared to spinopelvic stiffness.

Summary: This study found significant differences in spinopelvic parameters between patients with hip primary osteoarthritis and healthy controls, including reduced hip flexion and increased lumbar flexion in patients. Patients showed a higher percentage of spinopelvic hypermobility. Therefore, the impact of spinopelvic differences should be considered before total hip arthroplasty.
