BACKGROUND: A wide clinicopathologic spectrum of a chordoma exists. Brachyury constitutes as its most useful diagnostic immunohistochemical (IHC) marker. METHODS: During a 7-year-period, 4 unusual histopathologic types of chordomas were identified. Immunohistochemistry was performed by polymer technique. RESULTS: Clinicopathologic features of the 4 cases are as follows: Cases 1 and 2: Two tumors occurred in the sacrococcygeal and lumbosacral regions of a 42-year-old male and a 34-year-old female, respectively...

PURPOSE: To determine the incidence of pseudarthrosis at the osteotomy site after three-column spinal osteotomies (3-COs) with posterior column reconstruction. METHODS: 82 consecutive adult 3-COs (66 patients) with a minimum of 2-year follow-up were retrospectively reviewed. All cases underwent posterior 3-COs with two-rod constructs. The inferior facets of the proximal level were reduced to the superior facets of the distal level. If that was not possible, a structural piece of bone graft either from the local resection or a local rib was slotted in the posterior column defect to re-establish continual structural posterior bone across the lateral margins of the resection...

BACKGROUND: Sacrum is a triangular bone placed in the base of the spine and formed by the synostosis of five sacral vertebrae (S1-S5). Its upper part is connected with the inferior surface of the body of L5 vertebra forming the lumbosacral joint, while its lower part is connected with the base of the coccyx forming the sacrococcygeal symphysis, an amphiarthrodial joint. The existence of four pairs of sacral foramen in both anterior and posterior surface of the sacrum is the most common anatomy...

This study tested the hypothesis that sacral neuromodulation, i.e. electrical stimulation of afferent axons in sacral spinal root, can block pudendal afferent inhibition of the micturition reflex. In α-chloralose anesthetized cats, pudendal nerve stimulation (PNS) at 3-5 Hz was used to inhibit bladder reflex activity while the sacral S1 or S2 dorsal root was stimulated at 15-30 Hz to mimic sacral neuromodulation and to block the bladder inhibition induced by PNS. The intensity threshold (T) for PNS or S1/S2 dorsal root stimulation (DRS) to induce muscle twitch of anal sphincter or toe was determined...

Postcranial remains of Boreogomphodon from the Upper Triassic of North Carolina are described and compared to those of other known traversodontid cynodonts. The postcranial skeleton of Boreogomphodon is characterized by four sacral ribs, simple ribs lacking costal plates, the extension of the scapular neck below the acromion process, a short scapular facet on the procoracoid, a concave anterior margin of the procoracoid, humerus entepicondyle with smooth corner, and the presence of a fifth distal carpal. Four types of ribs are identified among traversodontids: 'normal' form, tubercular rib, costal plate, and Y-shaped rib...

A monolateral sacrum fracture was primarily diagnosed with a CT and treated with PMMA augmented SI screw fixation. The following CT showed an unexpected contralateral fracture which led to the need for a lumbopelvic stabilization. In the course of 6 months, successively occurring adjacent fractures required recurrent vertebroplasty. Most of these fractures could only be diagnosed through MRI. It remains unclear, whether initially even the contralateral sacral ala was fractured.

Introduction Pedicle screw insertion is the mainstay of thora-cic and lumbosacral posterior spinal instrumentation. However, it may be associated with complications such as screw mal-positioning. The purpose of this study was to develop a pilot study to compare the accuracy of robot-guided screw insertion versus hand-guided screw placement for spinal instrumentation. The hand-guided screws were placed with assistance from computerized tomography (CT) stealth guidance or fluoroscopy. Materials and methods A retrospective analysis of medical records was done for all patients that had pedicle screw insertion for instrumentation between the dates of December 2013 and January 2016 with post-screw placement CT imaging...

OBJECTIVES: This study aimed to evaluate surgical and clinical outcomes of laparoscopic mesh-less cervicosacropexy for the treatment of uterovaginal prolapse. METHODS: This single institutional review board-approved prospective cohort study enrolled 46 consecutive, sexually active symptomatic women requiring surgical correction of uterovaginal prolapse, from July 2013 to March 2016. After supracervical laparoscopic hysterectomy, the cervix was suspended to the anterior longitudinal ligament of the sacral promontory through a continuous suture with plication and shortening of the right uterosacral ligament...

OBJECTIVES: The aim of this prospective, randomized, multicenter, single-blind, 4 × 4 crossover study was to estimate the effect of 4 InterStim cycling settings (continuous, 16 seconds on/8 seconds off, 10 minutes on/10 minutes off, and 30 minutes on/23.5 hours off) on efficacy, Global Response Assessment, and safety. METHODS: Eligible women implanted for at least 3 months for urgency urinary incontinence (UI) were enrolled, and daily diaries were collected. General linear mixed models were used to estimate the cycling effect on efficacy...

INTRODUCTION: The arterial basket of the conus medullaris is one of several anastomoses between the anterior and posterior spinal arteries. The anatomy of this structure has attracted little attention. This work sought to investigate its configuration in human spinal cords. MATERIALS AND METHODS: Spinal cords from male and female cadavers (n=32) were injected with colored latex through the intercostal, lumbar, medial sacral and the posterior trunks of the hypogastric arteries...

OBJECTIVE: A hydatic cyst (HC) is a zoonotic infection affecting the liver and lungs, with rare spinal involvement. We discuss the long-term results of 8 spinal HC patients who were monitored at our clinic for 7-15 years. METHODS: The demographic data and clinicopathological parameters of 8 spinal HC patients diagnosed between 2000-2016 were evaluated for their contribution to recurrence and long-term follow-up results were examined. RESULTS: Four male and 4 female patients with a median age of 30...

BACKGROUND: We aimed to explore the prognosis and risk factors influencing tumor recurrence in surgery-treated patients with primary sacral tumors. METHODS: Fifty-six patients between February 2011 and December 2016 in Yishui Central Hospital with primary sacral tumors were selected and treated with radical surgeries. The perioperative outcomes and postoperative neurological functions were observed. After postoperative follow-up, the overall survival time (OS), disease-free survival time (DFS), and recurrence were recorded to analyze the potential risk factors influencing tumor recurrence...

BACKGROUND: Male urinary incontinence adversely affects health-related quality of life and is associated with significant psychosexual and financial burden. The two most common forms of male incontinence are stress urinary incontinence (SUI) and overactive bladder (OAB) with concomitant urge urinary incontinence (UUI). OBJECTIVE: The objectives of this article are to briefly review the current understandings of the pathophysiological mechanisms in SUI and OAB/UUI, and offer a set of practical, action-based recommendations and treatment strategies...

Sacral-iliac fixation techniques may be indicated in the management of various lumbosacral pathologies including spinal degeneration, infection, tumour resection, fracture, pseudarthrosis, correction of spinal deformities involving long fusion constructs to the sacrum and cases with poor sacral fixation. There are a number of options for lumbosacral fixation each with their own advantages and disadvantages. Though S2-alar-iliac (S2AI) have demonstrated promising advantages over alternatives, the complex anatomy of the spinopelvic region demands precise insertion of the screws to create a biomechanically robust construct safely...
