CASE DESCRIPTION A 14-week-old 7.7-kg (16.9-lb) sexually intact female Golden Retriever was evaluated because of urine dripping from the caudoventral aspect of the abdomen. CLINICAL FINDINGS Ultrasonography, radiography, excretory CT urography, and vaginocystourethroscopy were performed. Results indicated eversion of the bladder through the ventral abdominal wall with exposure of the ureterovesicular junctions, pubic diastasis, and an open vulva and clitoral fossa. Clinical findings were suggestive of bladder exstrophy, a rare congenital anomaly...

BACKGROUND: Direct anterior approach total hip arthroplasty (THA) with fluoroscopic assistance is growing in popularity. Variables such as pelvic tilt, c-arm technique, and patient positioning can affect the perceived fluoroscopic view. This study evaluates the effect of these variables on the position of the acetabular component. METHODS: Forty-one hips in 40 patients undergoing direct anterior arthroplasty THA with fluoroscopic assistance underwent routine postoperative radiographs and postoperative pelvic computed tomography scan...

Numerous new fossils have driven an interest in reproduction of early birds but direct evidence remains elusive. No Mesozoic avian eggs can be unambiguously assigned to a species, which hampers our understanding of the evolution of contact incubation, which is a defining feature of extant birds. Compared to living species eggs of Mesozoic birds are relatively small, but whether the eggs of Mesozoic birds could actually have borne the weight of a breeding adult has not yet been investigated. We estimated maximal egg breadth for a range of Mesozoic avian taxa from the width of the pelvic canal defined by the pubic symphysis...

BACKGROUND CONTEXT: Fusion typically consists of joint preparation, grafting and rigid fixation. Fusion has been successfully used to treat symptomatic disruptions of the SIJ and degenerative sacroiliitis using purpose-specific, threaded implants. The biomechanical performance of these systems is important but has not been studied. PURPOSE: To compare two techniques for placing primary (12.5mm) and secondary (8.5mm) implants across the SIJ. STUDY DESIGN: A human cadaveric biomechanical study of sacroiliac joint (SIJ) fixation...

Transperineal ultrasound (TPUS) allows for objective quantification of mid-sagittal urogenital mechanics, yet current practice omits dynamic motion information in favor of analyzing only a rest and a peak motion frame. This work details the development of UROKIN, a semi-automated software which calculates kinematic curves of urogenital landmark motion. A proof of concept analysis, performed using UROKIN on TPUS video recorded from 20 women with and 10 women without stress urinary incontinence (SUI) performing maximum voluntary contraction of the pelvic floor muscles...

INTRODUCTION: Radiographic abnormalities of the symphysis as well as the formation of accessory clefts, indicating injury at the rectus-adductor aponeurosis, reportedly relate to longstanding groin pain in athletes. However, yet, no systematic classification for clinical and scientific purposes exists. We aimed to (1) create a radiographic classification based on symphysography; (2) test intra- and interobserver reliability; (3) characterise clinical significance of the morphologic patterns by evaluating success of injection therapy...

Objectives. The present study addresses the following two main questions: a) Is the pattern of skeletal ageing observed in well-known western European reference collections applicable to modern eastern Baltic populations, or are population-specific standards needed? b) What are the consequences for estimating the age-at-death distribution in the target population when differences in the estimates from reference data are not taken into account? Materials and methods. The dataset consists of a modern Lithuanian osteological reference collection, which is the only collection of this type in the eastern Baltic countries (n = 381); and two major western European reference collections, Coimbra (n = 264) and Spitalfields (n = 239)...

Penile Mondor's disease is a rare condition characterized by sclerosing thrombophlebitis of the superficial dorsal penile vein. Usually its causes are benign, but it is also evident in cancer patients. We report the case of a 62-year-old man with a cT4 anal cancer (infiltration of corpora spongiosa and penile bulb), associated with extensive loco-regional lymphadenopathy, who developed painful lumps in the midline of the anterior penile surface while receiving radical chemoradiotherapy. Physical examination revealed two palpable cord-like swellings located 2 cm from the pubic symphysis...

Patients with pubic symphysis instability who had failed nonoperative treatments may benefit from surgical repair. This disease process is rare, most commonly seen in postpartum women and athletes, and its surgical treatment is invasive and nonphysiological. Currently described surgical interventions, although limited, include plating, which provides an overly rigid construct with the risk of failure and possibly poor long-term outcomes particularly in athletes, and treatments such as curettage, more commonly used in the treatment of osteitis pubis...

OBJECTIVE: Recent clinical study suggests an advantage to adding an iliosacral screw to the anterior fixation construct for anteroposterior compression type-2 (OTA/AO type 61-B1), partially unstable open-book pelvic ring injuries. Others have described stress examination to determine any required supplemental fixation. However, biomechanical studies investigating iliosacral fixation requirements for this injury are lacking. Our objective was to determine whether adding an iliosacral screw to symphyseal plate fixation decreases displacement in a well-defined open-book pelvic ring injury model...

PURPOSE: To study correlations between sonographic and urodynamic findings after suburethral sling surgery. METHODS: This is a retrospective study on 141 women who had multichannel urodynamic testing and translabial 4D ultrasound after suburethral sling surgery between 2006 and 2016. The sling-pubis gap, i.e., the distance between sling and infero-posterior margin of the pubic symphysis on Valsalva, and urethral motion profile were determined. The urethral motion profile was assessed by calculating the mobility vectors of 6 equidistant points along the length of urethra from bladder neck to external urethral meatus, against the dorsocaudal margin of the symphysis pubis on Valsalva...
