In the last decade, there has been renewed interest in the study of the right ventricle. It is now well established that right ventricular function is a strong predictor of mortality, not only in heart failure but also in pulmonary hypertension, congenital heart disease, and cardiothoracic surgery. The right ventricle is part of a cardiopulmonary unit with connections to the pulmonary circulation, venous return, atria, and left ventricle. In this context, ventriculoarterial coupling, interventricular interactions, and pericardial constraint become important to understand right ventricular adaptation to injury or abnormal loading conditions...

BACKGROUND: Magnetically controlled growing rod (MCGR) concept was introduced with the premise of minimizing the repetitive lengthening surgeries, which is default in traditional growing rod (TGR) treatment for early-onset scoliosis (EOS). Despite good radiographic outcomes, previous studies did not compare identical patient groups in terms of etiology and deformity characteristics; therefore, a true comparison of the MCGR and TGR is essential. This study was designed to compare 2 techniques in terms of clinical, radiologic, and health-related quality of life (HRQoL) outcomes...

BACKGROUND: Nonsurgically treated patients with AIS demonstrate altered scapular kinematics and decreased patient-reported shoulder function compared with typically developing adolescents. It is unknown whether surgical correction of the spine deformity has beneficial or detrimental effects on scapulothoracic joint function, as previous assessments of shoulder function following surgery have only focused on humerothoracic motion. The objective of this study was to perform a comprehensive analysis of scapular kinematics before and after PSF and compare postoperative scapular kinematics in AIS to those of a typically developing cohort...

BACKGROUND: Breast implants may be responsible for secondary deformities produced by parenchymal atrophy. However, few studies in the literature have reported changes in breast tissue after augmentation surgery. In this study, the breast thickness of patients undergoing breast augmentation was monitored by ultrasound, and correlations with surface, volume and projection measurements were examined. METHODS: We studied the parenchymal thickness at the lower pole of the breast with ultrasound in 36 women (72 breasts)...

BACKGROUND: Interportal and T-capsulotomies are popular techniques for exposing femoroacetabular impingement deformities. The difference between techniques with regard to the force required to distract the hip is currently unknown. PURPOSE: To quantify how increasing interportal capsulotomy size, conversion to T-capsulotomy, and subsequent repair affect the force required to distract the hip. STUDY DESIGN: Controlled laboratory study. METHODS: Eight fresh-frozen cadaveric hip specimens were dissected and fixed in a materials testing system, such that pure axial distraction of the iliofemoral ligament could be achieved...

A subtrochanteric fracture of the femur accompanying pre-existing osteoarthritis of the ipsilateral hip is rare. A deformity of the hip joint complicates the insertion of the intramedullary nail and varus malreduction is anticipated when surgery is performed on a fracture table with a perineal post. We report a successful case of intramedullary fixation performed in the lateral decubitus position and discuss the importance of avoiding varus and the superiority of the lateral position in surgery.

BACKGROUND: Standard open calcaneal osteotomies to correct hindfoot malalignment have been associated with high complication rates, including nerve damage and wound infection. This has resulted in the development of minimally invasive techniques such as the percutaneous endoscopically assisted calcaneal osteotomy (PECO), which in cadaver studies has been shown to be potentially safer than open surgeries. The aim of this study was to demonstrate the safety and effectiveness of PECO in a clinical setting, with regard to neurovascular injury rates, infection, and short-term radiographic and functional outcomes...

Importance: Autologous fat transfer (AFT or fat grafting) has become an invaluable tool for the correction of disfiguring deformities after breast cancer surgery. However, clinical and animal studies have shown conflicting results regarding its oncologic safety. Objective: To determine whether exposure to AFT vs conventional breast reconstruction is associated with increased rates of cancer relapse in patients with breast cancer. Design, Setting, and Participants: This matched cohort study involved retrospective medical record review to identify all patients in a local patient database receiving AFT between 2006 and 2014...

Anterior abdominal wall reconstruction surgery in patients who have undergone multiple laparotomies is associated with a high risk of complications. For this reason, minimally invasive surgery techniques are used to avoid abdominal compartment syndrome, to enhance wound healing and to reduce postoperative pain and blood loss. This paper presents a case of a patient who was admitted to the Department of General Surgery in Puck Hospital as a result of extensive anterior abdominal wall deformation with an end descending colostomy...

Bilateral sagittal split ramus osteotomy (BSSO) surgery is used to correct various dento-skeletal deformities. Clinical outcomes are critically dependent on accurate and proper positioning of skeletal units created by BSSO. Monitoring skeletal changes postoperatively is a major part of follow-up. Between January 2015 and December 2015, 24 patients underwent BSSO surgery without any other segmental osteotomy (mean age, 29.9 ± 14.2 [range, 17-67] years; 18 females). Cephalometric X-rays and cone-beam computed tomography scans were performed 6 weeks and 12 months postoperatively...

There is an increased trend in complex spine deformity cases toward a two attending surgeon approach, but the practice has not become widely accepted by payers. Multiple studies have shown that spine surgery complications increase with the duration of case, estimated blood loss, and use of transfusions, as well as in certain high-risk populations or those requiring three-column osteotomies. Dual-surgeon cases have been shown to decrease estimated blood loss, transfusion rate, surgical times, and therefore complication rates...

BACKGROUND CONTEXT: Previous studies have found an association between mental illness and poor outcomes in spine surgery, but little is known about the effects of depression and/or anxiety on the adult spinal deformity population. In addition, most relevant studies exclusively focused on the lumbar spine and had relatively small patient sizes. PURPOSE: The aim of this study was to investigate whether adult spinal deformity patients with depression and/or anxiety have an increased risk of postoperative complications and reoperation following posterior thoracolumbar spinal surgery...
