INTRODUCTION: The goal in the treatment of developmental dysplasia of the hip (DDH) is to achieve a stable and concentric reduction and to create a congruent relationship between the femoral head and the acetabulum. This study discusses the causes of loss of reduction in DDH patients who had a concentrically reduced hip at the time of removal of the hip spica cast and cessation of brace use and who later appeared with hip redislocation after mobilisation and ambulation. In addition, the possible interventions in such cases are also discussed...

The ability to control the body's center of mass (CoM) is critical for preventing falls, which are a major health concern in aging populations. Control of the CoM has been assessed by characterizing dynamic margins of stability (MoS) which capture the dynamic relationship between the CoM and the base of support. Accurate estimation of CoM dynamics is best accomplished using a full-body marker set. However, a number of simplified estimates have been used throughout literature. Here, we determined the biases and sources of bias when computing MoS using four simplified CoM models, and we characterized how these biases varied in straight walking versus turning...

BACKGROUND: Testing for mechanical stability in pelvic ring fractures is advocated for the initial assessment and management of pelvic ring fractures. A survey among trauma surgeons showed that 91% agree with this recommendation. The aim of the present study was to describe the actual workup of patients with a high risk for unstable pelvic fractures in daily routine. METHODS: We performed a prospective multicenter observational study on patients admitted to the emergency room with suspected pelvic ring fractures...

Musculoskeletal complaints are highly prevalent in clarinetists and are related to high arm load while playing. It is hypothesized that postural exercise therapy may be used to adapt muscle activity patterns while playing and thus contribute to better sound quality. The goal of the present study was to investigate the relationship between body posture, muscle activity, and sound quality in clarinetists while playing the instrument in two different postures, their habitual sitting posture (control, CO) vs an experimental sitting posture (EXP) based on Mensendieck postural exercise therapy, method Samama...

In 2002, the U.S. Food and Drug Administration approved the Essure system for permanent birth control. Implantation with this device offers a minimally invasive option for permanent female contraception that is placed during a brief office visit. Unlike laparoscopic tubal sterilization, the Essure procedure requires no hospitalization or general anesthesia, resulting in minimal recovery time. After a decade of stability in the report of adverse effects, the U.S. Food and Drug Administration noted a sharp increase in patient-reported adverse events, including chronic pelvic pain, irregular bleeding, allergic reactions, and autoimmune-like reactions...

Surgical treatment of unstable pelvic fractures Type C, has a vertical instability that is not controlled by traction and supine; therefore, orthopedic and functional treatments undertaken by default are sources of complications. The closed reduction with percutaneous sacroiliac fixation solves the problem of vertical instability; but at the cost of learning the method. Five patients with unstable pelvic fractures; were treated by percutaneous sacroiliac fixation. This reliable and useful method in the stabilization of unstable pelvic fractures...

Severe pelvic traumatisms are associated with elevated mortality because of the high risk of exsanguination from multiple sources of bleeding. Treatment should encompass resuscitation, bone stabilization and hemorrhage control by arterio-embolization or surgery. Pre-peritoneal packing has been described in hemodynamically unstable patients who need damage control. The surgical technique of this simple and effective procedure is fully described by the authors with some complementary useful technical advices.

INTRODUCTION: Pelvic organ prolapse can significantly reduce quality of life of affected women, with many cases requiring corrective surgery. The rate of recurrence is relatively high after conventional prolapse surgery. In recent years, alloplastic meshes have increasingly been implanted to stabilize the pelvic floor, which has led to considerable improvement of anatomical results. But the potential for mesh-induced risks has led to a controversial discussion on the use of surgical meshes in urogynecology...

BACKGROUND: Determining whether a Tile-B2 pelvic fracture is stable is very challenging. We sought to identify the role of ultrasonography in determining the stability of Tile-B2 pelvic fractures. METHODS: We collected the clinical data of patients with Tile-B2 pelvic fractures who presented at Xi'an Hong-Hui Hospital between June 1, 2016, and August 5, 2016. The treatment strategy of each patient was determined by a team of senior surgeons in the department. A single sinologist observed the movement of the fracture sites in patients during rest, under compression, and during separation to determine fracture stability...

Pelvic fractures are uncommon in children and account for between 0.3 and 7.5% of all pediatric injuries. Open pelvic fractures only account for up to 12.9% of all pediatric pelvic fractures. An unusual case of open complete anterior sacro-iliac joint dislocation in a 4-year-old boy is presented with a long-term follow-up. The multidisciplinary approach is reported with review of the current literature. A 4-year-old male presented to our institution in January 2012 after having been run over by a tractor. He presented with gross hemodynamical instability, MISS of 25, and an unstable lateral compression type III pelvic fracture with complete anterior dislocation of the left hemipelvis and a groin wound extending into the left thigh...
