Recently spinopelvic balance and mobility, i.e. the dynamic interaction of the spine, pelvis and the femur in the sagittal plane between different postures, has been identified as a relevant factor influencing the outcome of primary total hip arthroplasty (THA). Individual spinopelvic balance and mobility seem to affect patient reported outcome and the risk of impingement and dislocation following THA. The aim of this article is to provide a concise overview of normal and pathologic spinopelvic alignment, to characterize relevant spinopelvic parameters and the diagnostic assessment in patients with hip OA and to discuss potential implications for THA with respect to implant selection and component orientation...

Background: Prior spinal fusion significantly increases the risk of dislocation in patients after total hip arthroplasty (THA). Owing to these high risks, surgeons may use dual-mobility (DM) constructs in these patients to optimize hip stability. However, there is a paucity of data on the outcomes of DM constructs in patients who underwent prior spinal fusions. Methods: We retrospectively identified 80 patients (86 THAs) who underwent a spinal arthrodesis and a subsequent posterior approach THA with a DM construct...

Morel-Lavallée lesions are chronic seromas due to closed degloving injuries, resulting from blunt trauma. They most commonly occur over the greater trochanteric, gluteal and flank regions. We present a case of retrosacral Morel-Lavallée lesion. Initial ultrasound demonstrated a fluid collection lying between the subcutaneous fat and the underlying fascia superficial to the sacrum. Following repeated ultrasound-guided aspirations, further recurrence of a superficial pre-sacral seroma was confirmed with MRI...

Adolescent idiopathic scoliosis (AIS) is a complex deformity that often leads to loss of coordination and dynamic posture. However, there is a lack of understanding on inter-segmental coordination in AIS. The purpose of this study was to compare spinal range of motion (ROM), as well as the relations to coupling angles (CA) in the spinal region during trunk rotation, between AIS and control subjects. There were 14 subjects with right thoracic AIS and 18 control subjects who participated in the study. All subjects were asked to perform five repeated axial trunk rotations in standing while holding a bar...

BACKGROUND: Vaginal vault prolapse is the most frequent long-term complication in patients undergoing hysterectomy and sacralcolpopexy is considered the gold standard. We report our surgical strategy maintaining single-arm mesh when the sacral promontory is not accessible to fix the mesh for an unknown sacral osteophytosis during a laparoscopic sacralcolpopexy. This is significant because, to our knowledge, the bone variant as a procedure limiting factor has never been described before...

Background: The technique of a percutaneous transpedicular biopsy of spinal lesions has been shown to be a useful alternative to paraspinal biopsy for vertebral body lesions in the thoracic and lumbosacral spine. Percutaneous vertebral biopsy is less invasive, cost-effective, and is suitable for patients with intractable back pain and vertebral body lesions that are detected with noninvasive imaging modalities. Objective: The purpose of this study was to establish the diagnostic utility and spectrum of fluoroscopy-guided percutaneous transpedicular biopsies of the thoracolumbar spine performed at our institution...

The aim of this study was to investigate the variability of the slope of the pelvis in different dog breeds and the correlation between pelvic slope and femoral subluxation. The sacrum-pelvis angle (SPA), the angulation between the sacrum and the axis of the ilium was created to represent the differences in the slope of the pelvis on lateral pelvic radiographs. The Norberg angle (NA) was used to quantify the femoral subluxation on hip-extended radiographs. Archived standard ventrodorsal hip radiographs and lateral lumbosacral radiographs of the same dogs were retrieved and a single observer measured the SPA and the NA in each case...

PURPOSE: Some clinical situations, such as great sagittal imbalance, high-grade isthmic spondylolisthesis or sacral malunion could require a sacral osteotomy to decrease pelvic parameters, horizontalize the sacrum or correct sacral malunion. Here is described a novel technique to perform a sacral osteotomy to decrease pelvic parameters with a lumbo-pelvic construct, with first a sacral slope decrease, then a pelvic tilt decrease. METHODS: Simulations have been performed using tridimensional reconstructions of the lumbar spine and pelvis, made from CT-scan images of a healthy individual...

BACKGROUND: Neoplasms of the sacrum and pelvis are challenging to manage due to their complex vascularity and size and are at high risk of bleeding during resection. Intra-aortic balloon occlusion (IABO) has been used in trauma to control massive blood loss, but its efficacy and safety in oncologic sacral and pelvic surgery are unknown. The primary objective of this systematic review and meta-analysis was to assess the effectiveness of IABO in providing hemorrhage control during resection of sacral and pelvic tumors...

STUDY DESIGN: Retrospective single-center study. OBJECTIVE: Investigate the effect of posterior instrumentation on the relationship between lordosis and kyphosis. METHODS: Surgically treated patients with a minimum of 6 months of follow-up were analyzed. Asymptomatic volunteers served to show the normal anatomical relationship between thoracic and lumbar curves. Patients were stratified based on postoperative instrumentation: "Thoracic Fusion" = complete fusion of thoracic spine; "Lumbar Fusion" = complete fusion of lumbar spine; and "Complete Fusion" = fusion from sacrum to at least T5...

STUDY DESIGN: Retrospective study. OBJECTIVE: To report the incidence of revision surgery due to mechanical failure following pedicle subtraction osteotomy (PSO) in adult spinal deformity (ASD) patients. PSO allow major surgical correction of ASD, although; the risk of mechanical complications remains considerable. Previous reports have been based on smaller cohorts or multicenter databases and none have utilized competing risk (CR) survival analysis. METHODS: All ASD patients undergoing PSO surgery from 2010 to 2015 at a single, tertiary institution were included...

BACKGROUND/AIM: Chordomas often affect the sacrum with a high predilection for local-regional recurrence. Patients typically retain their ability to ambulate, and the development of metastatic disease in the periacetabular region can have significant morbidity and pain with ambulation. The purpose of the study was to describe the outcome of patients undergoing a hip arthroplasty following resection of a sacral chordoma. PATIENTS AND METHODS: From 1990 to 2015, 84 patients underwent sacrectomy for chordoma, while four of these (5%) patients underwent hip arthroplasty...
