Purpose To develop and test a computed tomography (CT)-based predictive model for major arterial injury after blunt pelvic ring disruptions that incorporates semiautomated pelvic hematoma volume quantification. Materials and Methods A multivariable logistic regression model was developed in patients with blunt pelvic ring disruptions who underwent arterial phase abdominopelvic CT before angiography from 2008 to 2013. Arterial injury at angiography requiring transarterial embolization (TAE) served as the outcome...

BACKGROUND: Cranial cruciate ligament (CrCL) insufficiency is a degenerative condition that is a common cause of pelvic limb lameness and osteoarthritis in dogs. Surgical therapies developed to treat dogs with naturally occurring CrCL insufficiency aim to address the resultant instability, but the in-vivo alterations in stifle kinematics associated with CrCL insufficiency have not been accurately defined. The objective of this study was to quantify the 3-dimensional femorotibial joint kinematics of dogs with naturally occurring cranial cruciate ligament (CrCL) insufficiency during ambulation...

BACKGROUND: Cup malposition is a common cause of impingement, limitation of ROM, acceleration of bearing wear, liner fracture, and instability in THA. Previous studies of the safe zone based on plain radiographs have limitations inherent to measuring angles from two-dimensional projections. The current study uses CT to measure component position in stable and unstable hips to assess the presence of a safe zone for cup position in THA. QUESTIONS/PURPOSES: (1) Does acetabular component orientation, when measured on CT, differ in stable components and those revised for recurrent instability? (2) Do CT data support historic safe zone definitions for component orientation in THA? METHODS: We identified 34 hips that had undergone revision of the acetabulum for recurrent instability that also had a CT scan of the pelvis between August 2003 and February 2017...

BACKGROUND: Giant invasive spinal schwannomas (GISS) comprise a rare, specific subtype of schwannomas that extend over two spinal levels, erode vertebral bodies and invade extraspinal tissues. Optimal surgical management of resulting spinal instability has yet to be determined, and overall there is limited published literature on GISS. We report an innovative method used to treat a rare case of lumbosacral GISS using a triangular frame reconstruction to reconnect the spinal column to the pelvis after tumor debulking...

In recent years, it has become evident that tumor cells have immune escape mechanisms, and immune checkpoint inhibitor therapy (anti-PD-1/PD-L1 antibody) has shown benefit in various cancers. In endometrial tumors with microsatellite-instability (MSI), somatic mutations have the potential to encode ''non-self'' immunogenic antigens, and lymphocytes have been shown to infiltrate the tumor. Therefore, immune checkpoint inhibitor therapy might be effective in endometrial cancers with MSI. Expression of mismatch repair (MMR) proteins (MLH1, PMS2, MSH2, and MSH6), the presence of tumor-infiltrating lymphocytes (CD8+), and PD-1/PD-L1 expression were assessed by immunohistochemistry in 149 patients with endometrial cancer...

INTRODUCTION: Hip arthroscopy has become a standard procedure in the treatment of hip joint pain not related to osteoarthritis or dysplasia in the young and active patient. There has been increasing focus on the contribution of the hip capsule to function and on stability following hip arthroscopy. It has been suggested that capsular closure after hip arthroscopy may prevent microinstability and macroinstability of the hip joint and reduce revision rate. However, it remains unknown whether capsular closure should be performed as a standard procedure when performing hip arthroscopies, especially in patients without additional risk factors for instability such as hypermobility or dysplasia of the hip...

A 53-year-old obese woman was referred because of sudden onset of dyspnea and chronic vaginal bleeding. In addition to severe anemia, multiple pulmonary emboli were identified. Pelvic imaging showed an irregular-shaped mass in the region of the endocervix extending to the lower uterine segment. After successful anticoagulant therapy, followed by placement of an inferior vena cava filter, transabdominal hysterectomy and bilateral salpingo-oophorectomy were performed. An immunopathological study resulted in the diagnosis of endocervical serous carcinoma...

Obturator artery injury (OAI) from pelvic gunshot wounds (GSW) is a rarely reported condition. Hemorrhages from pelvic trauma (PT) are mostly venous. Arterial hemorrhages represent about 10-20% of PTs. When arterial hemorrhages from PT occur, they are a severe and deadly complication often causing significant hemodynamic instability and eventual shock. A 23-year-old male presented to our emergency service via a private vehicle with multiple gunshot wounds to both thighs and to the lower back, resulted in rectal and obturator artery (OA) injuries...

BACKGROUND: In the late stage of Spinal tuberculosis, the bony destruction and vertebral collapse often leads to significant kyphosis, presenting clinically as a painful gibbus deformity, with increased instability, vertebral body translations and increased risk of neurologic involvement. Vertebral column decancellation is thought to be suitable for most patients with severe rigid kyphosis. Surgimap Spine, could offer a pragmatic graphical method for the surgical planning of osteotomies...

BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is increasingly used as a noninvasive clamp of the aorta after diverse posttraumatic injuries. Balloon inflation in zone 3 (from the lower renal artery to the aortic bifurcation) can be performed to stop ongoing bleeding after severe pelvic trauma with life-threatening hemorrhage. The aim of our study was to describe our 20-year experience with REBOA in terms of efficacy and safety in patients with a suspicion of severe pelvic trauma and extreme hemorrhagic shock...

PURPOSE: Despite using a multidisciplinary treatment approach, the mortality rate of patients with hemodynamic instability from severe pelvic fractures is still 40-60%. We evaluated the improvement of outcomes in this patient population after the establishment of a regional trauma center in Korea. METHODS: We retrospectively reviewed the medical charts of 50 patients with hemodynamic instability due to pelvic fractures between March 2011 and November 2016. Patients were divided into two groups: the pre-trauma center (PTC) group (n = 23) and trauma center (TC) group (n = 27)...

Chondrosarcoma is a malignant cartilage-forming neoplasm. It is difficult to treat because of resistance to both chemotherapy and radiation, making wide local excision the only treatment. This report presents an active, 43 year-old man who was diagnosed with recurrent clear cell chondrosarcoma of the proximal left femur, previously reconstructed with a total hip prosthesis, extending to the weight-bearing dome of the acetabulum. Cancer staging study revealed no signs of tumor dissemination at distance. Given the excellent functional status of the patient, the authors performed a Enneking-Dunham type periacetabular pelvic resection and resected en bloc, with the total hip prosthesis including 22 cm of the femur and a portion of the hip abductor apparatus...

Interventional radiologists are often called for emergent control of abnormal uterine bleeding. Bleeding, even heavy bleeding as a result of uterine fibroids is not a common emergent procedure; instead, pregnancy and pregnancy related conditions, trauma and malignancy associated with bleeding can be the source of many interventional radiology on call events or procedures. Postpartum hemorrhage (PPH) is the most common cause, and is defined as blood loss of 500mL after vaginal delivery or 1000mL after cesarean section...
