INTRODUCTION: The medial thighplasty is a procedure where patients may attain superior mobility, hygiene, and cosmesis. Most surgeons use attachment of the superficial fascial system (SFS) of the thigh flap to the Colles fascia, whereas others attach the SFS to the pubic ramus periosteum. Because of a high complication profile, we aim to elucidate the clinical, biomechanical, and anatomic qualities of the Colles fascia versus the pubic ramus periosteum. MATERIALS AND METHODS: We performed a 17-year retrospective review documenting clinical complications, a biomechanical analysis of sutures placed in different tissue layers of the thigh, and a histologic analysis surrounding the ischiopubic ramus...

Pre-eclampsia is a hypertensive disorder that is associated with adverse maternal and perinatal outcomes. It has been proposed that specific trace and macro elements associated with antioxidant activities may also play a contributory role in aetiology of pre-eclampsia. The aim of this study was to measure the concentrations of thirteen different elements in hair and serum samples from women with a diagnosis of pre-eclampsia and compare them with normotensive controls. Venous blood and pubic hair samples were collected from forty-three pre-eclamptic and twenty-three normotensive pregnant women...

OBJECTIVE: Our goal is to develop an interface that integrates chronic monitoring of lower urinary tract (LUT) activity with stimulation of peripheral pathways. APPROACH: Penetrating microelectrodes were implanted in sacral dorsal root ganglia (DRG) of adult male felines. Peripheral electrodes were placed on or in the pudendal nerve, bladder neck and near the external urethral sphincter. Supra-pubic bladder catheters were implanted for saline infusion and pressure monitoring...

BACKGROUND: While recent studies have addressed the biomechanical function of the ligamentum teres and provided descriptions of ligamentum teres reconstruction techniques, its detailed quantitative anatomy remains relatively undocumented. Moreover, there is a lack of consensus in the literature regarding the number and morphology of the acetabular attachments of the ligamentum teres. PURPOSE: To provide a clinically relevant quantitative anatomic description of the native human ligamentum teres...

PURPOSE: Although abdominal-based flaps remain the first choice for autologous breast reconstruction, alternative donor sites are necessary when the abdomen is unavailable. Abdominal donor site suitability is determined, at times, according to deep inferior epigastric perforator (DIEP)-protocol computed tomographic angiography (CTA) results. CTA provides information about the pelvis/upper thigh that can be used to evaluate the suitability of other donor sites. This study aimed to examine the utility of DIEP-protocol CTA in the assessment of a lateral thigh perforator (LTP) flap...

OBJECTIVE: To observe the effects of boundary conditions and connect conditions on biomechanics predictions in finite element (FE) pelvic models. METHODS: Three FE pelvic models were constructed to analyze the effect of boundary conditions and connect conditions in the hip joint: an intact pelvic model assumed contact of the hip joint on both sides (Model I); and a pelvic model assumed the hip joint connecting surfaces fused together with (Model II) or without proximal femurs (Model III)...

INTRODUCTION: Infectious osteomyelitis of the symphysis pubis, known as pubic osteomyelitis is a rare condition with potentially devastating consequences. To the best of our knowledge, this article is the first reported case of a military trainee presenting with pubic osteomyelitis. MATERIALS AND METHODS: We present a unique case of a patient who simultaneously suffered a combination of local recurrent stress to the symphysis pubis area, and slow-healing multiple palm and finger lacerations which probably acted as distant ports of bacterial entry that concomitantly led to his illness...

PURPOSE: Pubic arch interference (PAI), when it occurs, is often a limiting factor for patients pursuing brachytherapy treatment of prostate cancer. Pre-brachytherapy pubic arch evaluation is often performed by CT or transrectal ultrasound (TRUS), but MRI has increasingly replaced these modalities for prostate cancer evaluation. The purpose of this study was to determine if staging MRI could be used to evaluate PAI and compare it with these other imaging methods. METHODS AND MATERIALS: Forty-one consecutive patients undergoing brachytherapy evaluation had pelvic MRI-, CT-, and TRUS-based brachytherapy simulation...

BACKGROUND: Floating pubic symphysis (FPS) is a relatively rare injury caused by high-energy mechanisms. There are several fixation methods used to treat FPS, including external fixation, subcutaneous fixation, internal fixation, and percutaneous cannulated screw fixation. To choose the appropriate fixation, it is necessary to study the biomechanical performance of these different methods. The goal of this study was to compare the biomechanical characteristics of six methods by finite element analysis...

BACKGROUND: Although internal fixation is the definitive treatment in unstable pelvic fractures with disruption of the anterior arch and a vertical fracture of the sacrum (AO type C1.3), there have been no agreement of the best technique of internal fixation yet. We aimed to derive comparable objective data on stiffness and load to failure in this type of fracture fixations. METHODS: Synbone was modified into AO type C1.3 fracture model, while treatments were divided into six internal fixation treatment groups using tension band plate (TBP), symphysis pubis plate (SP) with iliosacral screw at S1 and S2 (IS S1-S2), pubic screw (PS) with iliosacral TBP, PS and IS S1-S2, SP and IS S1-S3, PS and S1-S3 and finally PS and IS S1-S3...

Spondyloepiphyseal dysplasia congenita (SEDC, OMIM #183900) is one of the type II collagenopathies caused by a heterozygous mutation in the COL2A1 gene. Although typical SEDC shows delay of pubic bone ossification on radiographs, atypical SEDC exists without this finding. We identified an atypical SEDC patient with a novel missense mutation in the C-propeptide region of COL2A1. This case suggests that a COL2A1 C-propeptide mutation can cause atypical SEDC.

The use of finite element analysis (FEA) to investigate the biomechanics of anatomical systems critically relies on the specification of physiologically representative boundary conditions. The biomechanics of the pelvis has been the specific focus of a number of FEA studies previously, but it is also a key aspect in other investigations of, for example, the hip joint or new design of hip prostheses. In those studies, the pelvis has been modelled in a number of ways with a variety of boundary conditions, ranging from a model of the whole pelvic girdle including soft tissue attachments to a model of an isolated hemi-pelvis...

OBJECTIVES: A warning from Health Canada suggests that testosterone increases blood pressure (BP). No evidence from large randomized controlled trials is available, and observational studies are confounded by ill-health lowering serum testosterone. To address the evidence gap, we assessed the association of pubertal testicular volume, as a reflection of testosterone production, with BP. METHODS: We examined whether testicular volume was associated with sex-, age-, and height-standardized BP z-score at ∼13 years in a population-representative Chinese birth cohort (n = 5195, 63% follow-up)...

The external oblique musculo-aponeurotic complex is an important contributor to the strength of the inguinal canal. The present case report describes the bilateral absence of the external oblique muscle in a patient. A 40-year-old male patient presented with a history of intermittent lower abdominal pain for 15 years which had increased over the past 2 years. Abdominal examination revealed bilateral reducible, incomplete, direct inguinal hernia. Elective bilateral Lichtenstein's mesh hernioplasty was planned for the patient...

AIM AND OBJECTIVE: To evaluate the effect of rehabilitation exercises combined with Direct Vagina Low Voltage Low Frequency Electric Stimulation (DES) on pelvic nerve electrophysiology and tissue function after delivery. BACKGROUND: Whether and how DES effects pelvic floor dysfunction (PFD) are not known clearly. DESIGN: This was a randomised, controlled clinical trial. METHODS: The 189 primiparous women 20-35 years old and with an episiotomy or second degree episiotomy tear were divided into three groups: the control group (n=60) received routine postpartum guidance 2 hours postpartum, the training group (n=63) performed rehabilitation exercises (Kegel exercises and pelvic movements) from 2 days postpartum until 3 months postpartum, and the combination group (n=66) received DES 15 times (3 times a week for 30 min at a time) beginning at the sixth week postpartum in addition to performing rehabilitation exercises...

RATIONALE: Obturator pyomyositis is a rare condition in children. Diagnosis is often delayed because of its rarity, and the vagaries of its presentation cause it to be easily be missed. Physicians should therefore familiarize themselves with this condition and consider it as a possible differential diagnosis in patients presenting with an acutely painful hip. Inflammatory syndrome is also frequent among sufferers and the MRI is a very sensitive diagnostic tool for obturator pyomyositis...

In forensic anthropology, age-at-death estimation typically requires the macroscopic assessment of the skeletal indicator and its association with a phase or score. High subjectivity and error are the recognized disadvantages of this approach, creating a need for alternative tools that enable the objective and mathematically robust assessment of true chronological age. We describe, here, three fully computational, quantitative shape analysis methods and a combinatory approach that make use of three-dimensional laser scans of the pubic symphysis...
