Congenital Uterine Anomaly and Pelvic Organ Prolapse: A Rare Case of Pelvic Organ Prolapse in a Complete Bicornuate Uterus with Successful Pregnancy Outcomes Undiagnosed until the Time of Sacrocolpopexy.

Gina Nam Sa Ra Lee

J Menopausal Med 2021 Apr;27(1):32-36

Department of Obstetrics and Gynecology, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Korea.

Müllerian development anomalies (MDAs) are most commonly diagnosed in the reproductive period. A bicornuate uterus is the result of a fusion defect of the Müllerian ducts, causing an abnormal fundal outline. Most of the cases are diagnosed early in life and present with obstetrical complications, such as recurrent pregnancy loss, preterm birth, intrauterine growth restriction, placental abruption, and cervical incompetence.

Radiological Outcomes and Complications of Vertical Expandable Titanium Rib Instrumentation in Congenital Scoliosis With or Without Rib Fusion: A Retrospective Study.

Cureus 2021 Mar 29;13(3):e14167. Epub 2021 Mar 29.

Division of Orthopaedic Surgery, Department of Surgery, McMaster University, Hamilton, CAN.

Introduction: In congenital anomalies of the thoracic spine, fusion in situ and hemi-epiphysiodesis are unsuitable surgical options, because three-dimensional thoracic deformity and insufficiency are uncorrectable. We aimed to evaluate the radiological outcome of vertical expandable titanium rib (VEPTR) application after follow-up in children with congenital scoliosis with or without rib fusion.

Methods: In our study, we included 58 patients with congenital scoliosis with or without fused ribs; all treated with VEPTR from 2005 to 2015 at our institute. Read More

Complications in ambulatory pediatric patients with nonidiopathic spinal deformity undergoing fusion to the pelvis using the sacral-alar-iliac technique within 2 years of surgery.

J Neurosurg Pediatr 2021 Apr 30:1-8. Epub 2021 Apr 30.

Objective: Significant investigation in the adult population has generated a body of research regarding proximal junctional kyphosis (PJK) and proximal junctional failure (PJF) following long fusions to the sacrum and pelvis. However, much less is known regarding early complications, including PJK and PJF, in the ambulatory pediatric patient. As such, the objective of this study was to address the minimal literature on early complications after ambulatory pediatric patients underwent fusion to the sacrum with instrumentation to the pelvis in the era of sacral-alar-iliac (S2AI) instrumentation.

Heel Lift for Skiing to Compensate for Corrected Sagittal Vertical Axis After Spinal Surgery: A Case Report.

Int J Spine Surg 2021 Feb 18;14(s4):S33-S36. Epub 2021 Jan 18.

Department of Orthopedic Surgery, Spine and Scoliosis Service, Hospital for Special Surgery, Weill Cornell Medical College, New York, New York.

Lateral lumbar interbody fusion (LLIF) and pedicle subtraction osteotomy are common procedures to correct adult spinal deformities. Little is known about returning postoperatively to a high-performance sport such as skiing after spinal surgery. We report a case of an alpine skier who underwent a LLIF procedure combined with a posterior corrective osteotomy and posterior instrumentation, who had difficulties returning to skiing postoperatively because of new spinal biomechanics.

Novel Graft Technique for Lumbopelvic Reconstruction After Sacral Tumor Resection: A Case Report.

Robert F McLain

JBJS Case Connect 2021 04 16;11(2). Epub 2021 Apr 16.

Spine and Orthopaedic Institute, St Vincent Charity Medical Center, Adjunct, Biomedical Engineering, Cleveland State University.

Case: Reconstruction after sacral tumor resection carries a high risk of nonunion and requires a slow return to weight-bearing. A bilateral iliac-crest graft, mobilized on a muscular pedicle, was used to graft and fuse the spine and pelvis after resection of a massive sacral schwannoma. Long-term follow-up and three-dimensional computed tomography imaging demonstrate rapid incorporation and solid fusion, with hypertrophy of the graft struts and excellent return to function.

Evaluation of Global Alignment and Proportion Score in an Independent Database.

Spine J 2021 Apr 12. Epub 2021 Apr 12.

Department of Orthopedic Surgery, Barnes-Jewish Institute of Health, Washington University, St Louis, Missouri, USA.

Background Context: Sagittal spinopelvic alignment has been associated with patient-reported outcome measures and mechanical complication rates. Recently, it was claimed that linear numerical values of pelvic tilt and lumbar lordosis measurements may be misleading for patients that have different magnitudes of pelvic incidence. The use of "relative" measurements embedded in a weighted scoring of Global Alignment and Proportion (GAP) was proposed. Read More

A Hybrid Tracking System of Full-Body Motion Inside Crowds.

Sensors (Basel) 2021 Mar 17;21(6). Epub 2021 Mar 17.

Institute for Advanced Simulation 7, Civil Safety Research, Forschungszentrum Jülich, 52428 Jülich, Germany.

For our understanding of the dynamics inside crowds, reliable empirical data are needed, which could enable increases in safety and comfort for pedestrians and the design of models reflecting the real dynamics. A well-calibrated camera system can extract absolute head position with high accuracy. The inclusion of inertial sensors or even self-contained full-body motion capturing systems allows the relative tracking of invisible people or body parts or capturing the locomotion of the whole body even in dense crowds.

Global sagittal alignment after surgery of right thoracic idiopathic scoliosis in adolescents and adults with and without thoracic hypokyphosis.

Sci Rep 2021 Mar 18;11(1):6294. Epub 2021 Mar 18.

Department of Imaging and Interventional Radiology, Faculty of Medicine, The Prince of Wales Hospital, The Chinese University of Hong Kong, Shatin, Hong Kong SAR, China.

This study aimed to characterize global sagittal alignment in adolescent idiopathic scoliosis (AIS) with normal kyphosis (NTK, kyphosis > 10°) and with thoracic hypokyphosis (THK, kyphosis < 10°), before and after posterior spinal fusion, and compare them with asymptomatic controls. 27 AIS girls and young adults with right thoracic curves were included (seventeen with age ≤ 18 years, then age > 21). Biplanar radiographies were acquired at baseline, immediate post-operatively, 1-year and 2-year follow-up, and 3D reconstruction of the spine and pelvis was performed. Read More

Sacroiliac joint arthropathy in adult spinal deformity patients with long constructs to the pelvis.

Clin Neurol Neurosurg 2021 Apr 3;203:106593. Epub 2021 Mar 3.

Department of Neurosurgery and Brain Repair, University of South Florida Morsani College of Medicine, Tampa, FL, USA. Electronic address:

Objective: Sacroiliac joint (SIJ) arthropathy is an increasingly recognized problem in adult spinal deformity patients undergoing long construct surgery. S2-alar-iliac (S2AI) screw instrumentation is thought to reduce morbidity from pelvic fixation in these patients.

The role of imaging in computer assisted tumor surgery of the sacrum and pelvis.

Curr Med Imaging 2021 Mar 2. Epub 2021 Mar 2.

IRCCS Policlinico di Sant'Orsola, Bologna. Italy.

The use of a navigation system allows precise resection of a tumor and accurate reconstruction of the resultant defect thereby sparing important anatomical structures and preserving function. It is an "image-based" system where the imaging (computed tomography and magnetic resonance imaging) is required to supply the software with data. The fusion of the preoperative imaging provides pre-operative information about local anatomy and extent of the tumor, so that it allows an accurate preoperative planning. Read More

The role of the fractional lumbosacral curve in persistent coronal malalignment following adult thoracolumbar deformity surgery: a radiographic analysis.

Spine Deform 2021 May 2;9(3):721-731. Epub 2021 Mar 2.

Department of Orthopaedic Surgery, Washington University School of Medicine in St. Louis, 660 Euclid Avenue, Campus Box 8233, Saint Louis, MO, 63110, USA.

Instrumentation of the sacroiliac joint with cylindrical threaded implants: A detailed finite element study of patient characteristics affecting fixation performance.

J Orthop Res 2021 Feb 23. Epub 2021 Feb 23.

Department of Mechanical Engineering, Polytechnique Montréal, Montreal, Quebec, Canada.

The sacroiliac joint (SIJ) is a known pain generator that, in severe cases, may require surgical fixation to reduce intra-articular displacements and allow for arthrodesis. The objective of this computational study was to analyze how the number of implants affected SIJ stabilization with patient-specific characteristics such as the pelvic geometry and bone quality. Detailed finite element models were developed to account for three pelvises of differing anatomy. Read More
