“…only 11% were unbalanced after the surgery. No significant variation of the SS as the SSA was associated to this restoration, in concordance with the lack of variation reported by others [16]. They had shown improvement of the sagittal balance in unbalanced preoperative population of patient after L5-S1 TDR, in particular in case of unbalanced patients with low SS values (Roussouly type 1 and 2).…”

The goal of this study was to evaluate the impact of anterior lumbar interbody fusion (ALIF) on L5-S1 level for restitution of distal segmental lordosis and to investigate its consequences on spino-pelvic parameters and the global sagittal balance. Overview of Literature: Lumbar surgery must be adapted to the spinal morphology in order to restore an adequate relation between pelvic and spinal parameters and especially to the pelvic incidence. Methods: An observational, prospective study was conducted between January 2013 and May 2017. Eighty-six patients were treated by L5-S1 ALIF procedure regardless of disc replacement above L5-S1 level. Thirty-seven patients were included and subset analyses were performed on 25 patients operated on an isolated ALIF L5-S1 (group 1), and 12 patients with hybrid surgery consisting of an L5-S1 ALIF procedure and a L4-L5 lumbar disc replacement (group 2). Clinical parameters were analyzed using Visual Analog Scale (VAS) and Oswestry Disability Index (ODI) at M0 (preoperative) and M12 (12 months). Lumbo-pelvic parameters were assessed on a standing full-spine X-ray, preoperatively and at M12 after surgery. Results: We observed a significant evolution of L1-S1 lumbar lordosis (p<0.001) with a significant increase of the distal arch L4-S1 lordosis (p<0.001) and decrease of the proximal arch lordosis (p=0.03). Preoperatively, 27% of the patients were unbalanced. Significant variation in sagittal balance parameters was observed, with a decrease of the sagittal vertebral axis (p<0.001). VAS and ODI improved significantly but no correlation was found. An evolution in the same direction was found in the two subgroup analyses. Conclusions: ALIF procedure on L5-S1 level allowed a reconstruction of lumbosacral segmental lordosis, modification of global lordosis, without variation of spino-pelvic parameters except an improvement in sagittal balance.

“…It has been considered for several decades that the cup should be oriented within a safe zone defined as 15° ± 10° of anteversion and 40° ± 10° of inclination according to the anterior pelvic plane (APP) . Some authors mentioned that this safe zone is not suitable because of the extreme interindividual variation of the pelvic kinematics . During daily activities such as in the sitting, standing, and supine positions, the pelvic tilt varies substantially to modify the functional orientation of the acetabulum and to adjust the range of motion of the hip according to these different positions.…”

“…5 Some authors mentioned that this safe zone is not suitable because of the extreme interindividual variation of the pelvic kinematics. [9][10][11][12] During daily activities such as in the sitting, standing, and supine positions, the pelvic tilt varies substantially to modify the functional orientation of the acetabulum and to adjust the range of motion of the hip according to these different positions. When the pelvis posteriorly tilts, as, for instance, in the sitting position, the acetabular anteversion is increased to enable higher flexion but reducing extension at the same time.…”

Objectives A new ultrasound‐based device is proposed to measure the patient‐specific pelvic tilt in different daily positions. The aim of this study was to assess the accuracy of this device as well as the intraobserver and interobserver precisions. Methods The accuracy was assessed by performing several tilt measurements with the device on a testing mechanical bench. The error was defined as the difference between the tilt measured with the device and the tilt provided by this test bench. Three physicians, a novice, an intermediate, and an expert user, were also asked to perform 10 measurements on 3 healthy volunteers with low, medium, and high body mass indices to analyze the intraobserver and interobserver precisions. These 10 measurements were performed in the standing, sitting, and supine positions. Results The mean accuracy of the device ± SD was 1.1° ± 0.7° (range, 0°–4.0°). The interobserver and intraobserver precisions were excellent whatever the body mass index and good to excellent according to the positions. There was no learning curve, and the time required to complete the measurements was approximately 5 minutes. Conclusions This study presents an accurate and precise noninvasive device for measurement of the pelvic tilt in different positions.

“…The systematic review by Riviere et al . includes 12 articles, which has demonstrated that high pelvic mobility is a risk factor for the sign of prosthetic impingement and dislocation after THA. Nonetheless, the high pelvic mobility causes an increase in acetabular anteversion from the supine position to the standing or sitting position.…”

The concept of the “safe area” of the acetabular prosthesis has a long history and has been recognized by many scholars. It is generally believed that postoperative hip dislocation rate is low, when the acetabular anteversion angle is placed in the range of 15° ± 10°. Despite this, hip dislocation is a common complication after total hip arthroplasty. In recent years, more and more scholars have paid attention to the influence of pelvic tilt on the acetabular anteversion angle. The concept of acetabular anteversion changes as the pelvic tilt changes, and is challenging the traditional acetabular prosthesis “safe area.” This study summarized the potential influencing factors of pelvic tilt and discussed the influence of the phenomenon on the anteversion angle of total hip arthroplasty (THA) acetabular prosthesis based on the literature review. We conclude that from the supine position to standing, followed by sitting, the pelvis tends to move backward. Pelvic sagittal activity, lumbar disease (ankylosing spondylitis), lumbar fusion (lumbar fusion, spine‐pelvic fusion), and other factors related to the tilt are THA risk factors for postoperative dislocation and revision. With the change of body position, the degree of acetabular anteversion is directly related to the degree of pelvic tilt. The acetabular anteversion varies greatly, which leads to increased hip prosthesis wear and even hip dislocation. The lateral X‐ray of the spine and pelvis is recommended in supine, standing, and sitting positions before THA. In addition, the pelvic tilt should be regarded as a reference of the acetabular prosthesis in the preoperative planning of THA.
