Abstract Background: The observational study aimed to investigate the change and correlations of the spinopelvic parameters as well as the relationships with the related symptoms in unilateral developmental dysplasia of the hip (DDH) patients. Methods: The clinical data of 22 unilateral DDH patients and 20 healthy volunteers were collected from 2016 to 2021. All patients and volunteers were taken the antero-posterior pelvic radiograph and the frontal and lateral radiography of the whole spine as a routine examination. And the clinical symptoms, signs and functions were measured according to Oswestry Disability Index and Low Back Pain Scoring System. Then the t test and Pearson correlation were used to analyze the data. Results: The Cobb(8.68±6.21°), L3(4.79±5.47°), CB(1.65±1.57cm), PT(15.02±9.55°) and TLK (7.69±6.66°) were significantly larger in the DDH patients, whereas LL(37.41±17.17°) were significantly smaller (P<0.05). As for the coronal spinopelvic parameters, CB was found to be associated with L3 (R=0.58, P<0.01). Of the sagittal spinopelvic parameters, SS was found to be associated with LL (R=0.48, P=0.02), and TLK was found to be related to ST and TK, respectively (R=0.49, P=0.02; R=-0.45, P=0.04). In terms of relations between the spinal and pelvic parameters, PI were found to be related to the SS (R=0.58, P<0.01). An analysis of relations revealed a correlation between the Oswestry Disability Index and Cobb(R=0.59, P<0.01), PT(R=0.49, P=0.02), TK(R=-0.46, P=0.03) and TLK(R=0.44, P=0.04). Furthermore, an analysis of relations revealed a correlation between Low Back Pain Scoring System and Cobb (R=-0.44, P=0.04), L3(R=-0.53, P=0.01), PT (R=-0.44, P=0.04), TK(R=0.46, P=0.03) and TLK(R=-0.43, P=0.05). Conclusion: The parameters are related to each other and compensate each other to maintain the balance of the coronal and sagittal planes of the spine. In addition, the change of some parameters is closely related to the quality of life of the patients, and can provide some clues for the clinical diagnosis and treatment of DDH.

Background: Improved medical care and increased life expectancy have led to a focus on the impact of adult spinal deformity (ASD) on health-related quality of life (HRQoL) in the field of the spine. Recently, there has been a paradigm shift in the evaluation and management of ASD regarding the important correlation between sagittal imbalance and clinical outcomes.Current Concepts: Loss of lumbar lordosis is recognized as a key driver of ASD followed by forward-leaning of the trunk, reducing thoracic kyphosis, pelvic retroversion, and knee flexion. Radiological assessment has been critical for evaluating ASD from the anteroposterior and lateral view of the whole spine radiograph. Important parameters include coronal, regional, global, and sagittal spinopelvic parameters. Especially, sagittal spinopelvic parameters significantly correlate with disability and HRQoL in patients with ASD, which can influence the process of decision-making with respect to the choice between conservative treatment and surgery.Discussion and Conclusion: Sagittal imbalance has been recently emphasized in patients with ASD. Therefore, the decision-making of ASD treatment should be focused on restoring harmonious alignment to prevent catastrophic complications and improvement of HRQoL.

Abstract Background Adult spinal deformities (ASD) represent a growing clinical condition related to chronic pain, disability and reduction in quality of life (QoL). A strong correlation among spinal alignment, spinopelvic parameters and QoL after spinal fusion surgery in ASD patients was thoroughly investigated over the last decade, However, only few studies focused on the relationship between lumbo-pelvic-femoral parameters - such as Femoral Obliquity Angle (FOA), T1 Pelvic Angle (TPA) and QoL. Methods Radiological and clinical data from 43 patients surgically treated with thoracolumbar posterior spinal fusion for ASD between 2015 and 2018 were retrospectively analyzed. The primary outcomes were the correlation between preoperative spino-pelvic-femoral parameters and postoperative clinical, functional outcomes and QoL. Secondary outcomes were: changes in sagittal radiographic parameters spino-pelvic-femoral, clinical and functional outcomes and the rate of complications after surgery. Results Using Spearman’s rank correlation coefficients, spinopelvic femoral parameters (FOA, TPA, pre and post-operative) are directly statistically correlated to the quality of life (ODI, SRS-22, pre and post-operative; > 0,6 strong correlation, p <  0.05). Stratifying the patients according pre preoperative FOA value (High FOA ≥ 10 and Normal/Low FOA <  10), those belonging to the first group showed worse clinical (VAS: 5.2 +/− 1.4 vs 2.9 +/− 0.8) and functional outcomes (ODI: 35.6+/− 6.8 vs 23.2 +/− 6.5) after 2 years of follow-up and a greater number of mechanical complications (57.9% vs 8.3% p <  0.0021). Conclusion Based on our results, preoperative FOA and TPA could be important prognostic parameters for predicting disability and quality of life after spinal surgery in ASD patients and early indicators of possible spinal sagittal malalignment. FOA and TPA, like other and better known spinopelvic parameters, should always be considered when planning corrective surgery in ASD patients.

Abnormal spinopelvic movements are associated with inferior outcomes following total hip arthroplasty (THA). This study aims to (1) characterize the agreement between dynamic motion and radiographic sagittal assessments of the spine, pelvis, and hip; (2) determine the effect of hip osteoarthritis (OA) on kinematics by comparing healthy individuals with pre-THA patients suffering from uni- or bilateral hip OA. Twenty-four OA patients pre-THA and eight healthy controls underwent lateral spinopelvic radiographs in standing and seated bend-and-reach (SBR) positions. Lumbar-lordosis (LL), sacral-slope (SS), and pelvic–femoral (PFA) angles were measured in both positions, and the differences (Δ) between SBR and standing were computed to assess spine flexion (SF), pelvic tilt (PT), and hip flexion (HF), respectively. Dynamic SBR and seated maximal trunk rotation (STR) tasks were performed at the biomechanics laboratory. Peak sagittal and axial kinematics for spine, pelvis, and hip, and range of motion (ROM), were calculated for SBR and STR. Radiograph readings correlated with sagittal kinematics during SBR for ΔLL and SFmax (r = 0.66, p < 0.001), ΔPT and PTmax (r = 0.44, p = 0.014), and ΔPFA and HFmax (r = 0.70, p < 0.001), with a satisfactory agreement in Bland–Altman analyses. Sagittal SBR spinal (r = 0.33, p = 0.022) and pelvic (r =0.35, p = 0.018) flexions correlated with the axial STR rotations. All axial spinopelvic parameters were different between the OA patients and controls, with the latter exhibiting significantly greater mobility and less variability. Bilaterally affected patients exhibited lower peak and ROM compared to controls. The biomechanics laboratory performed reliable assessments of spinopelvic and hip characteristics, in which the axial plane can be included. The sagittal and axial pelvic kinematics correlate, illustrating that pelvic rotation abnormalities are likely also contributing to the inferior outcomes seen in patients with abnormal spinopelvic flexion characteristics. Axial rotations of the pelvis and spine were least in patients with bilateral hip disease, further emphasizing the importance of the hip–pelvic–spine interaction.

Abstract Aim Reports have shown that spinopelvic mobility influences the outcome following total hip arthroplasty. The aim of this scoping review was to investigate the relationship between spinopelvic parameters (SPP) and symptomatic femoroacetabluar impingement (FAI). Method A systematic computer search of EMBASE, PubMed and Cochrane for literature related to SPPs and FAI was undertaken as per PRISMA guidelines. Clinical outcome studies and prospective/retrospective studies that investigated the role of SPPs in symptomatic FAI were included. Review articles, case reports and book chapters were excluded. Information extracted pertained to symptomatic cam deformities, pelvic tilt, deviations in acetabular version, decreases in pain-free hip range of motion (ROM) on dynamic hip movements and radiological signs of FAI. Results The literature search identified 46 papers out of 1168 investigating the link between SPPs and pathological processes characteristic of FAI. Anteior pelvic tilt was associated with radiographic over-coverage parameters of FAI. Three studies associated FAI pathology with a greater pelvic incidence (PI), while four associated it with a smaller PI. In dynamic movements, decreased posterior pelvic tilt and reduced saggital pelvic ROM was found in symptomatic FAI patients during hip flexion. Conclusions Our study shows that spinopelvic parameters can influence radiological and clinical manifestations of FAI, with pelvic incidence, acetabular version and muscular imbalances being aetiologically implicated. Individual spinopelvic mobility may predispose to the development of FAI, which may be amenable to non-surgical management. If FAI pathoanatomy already exists however, sagittal pelvic parameters can influence whether FAI symptoms develop, and the extent to which they do so.
