The authors describe a novel suture fixation technique that combines a doubled suture with a sliding knot. The knot can be tied in both open and arthroscopic surgery to fix torn tendons/ligaments and fractured/osteotomized bones. The advantages of the doubled-suture Nice knot include strength, adjustability, simplicity, and versatility. This technique, which has proven useful in the authors' pr...

In adolescents and young adults, femoral neck fractures often result from high-velocity trauma. These fractures are usually of vertical shear pattern. There is an increased incidence of avascular necrosis and non-union, which is difficult to treat. Non-union of fractured neck of femur in young adults is a serious problem. There is growing evidence that these fractures should be treated with an ...

INTRODUCTION In cases where the patient experiences trauma, the teeth may be fractured or a bone segment could be fractured causing misplaced teeth. Ceramic veneer restorations may be a solution for re-establishing the ideal position. The treatment of misplaced dental arch segment is presented and treatment options are discussed. CASE PRESENTATION A 30-years-old female Turkish patient had a h...

We present an approach for estimating the relative transformations between fragments of a broken cylindrical structure in 3d. To solve this problem, we first measure the orientation and position of the cylinder axes for each fragment by an adapted kind of Hough Transformation. The cylinder axes are an important feature for separation of fractured areas and for calculation of an initial repositi...

PURPOSE Bisphosphonates have been used to treat osteoporosis for more than ten years. However, complications associated with long-term administration of bisphosphonates, such as nonunion after pelvic insufficiency fracture or osteonecrosis of the jaw, have been recently reported in the literature. We investigated the relationships among the mechanical properties of the intact rat femur as well ...

Fragility fractures, those fractures which result from low level trauma, have a large and growing socio-economic cost in countries with aging populations. Bone-density-based assessment techniques are vital for identifying populations that are at higher risk of fracture, but do not have high sensitivity when it comes to identifying individuals who will go on to have their first fragility fractur...

Hachisu T, et al. BMJ Case Rep 2017. doi:10.1136/bcr-2017-222288 Description A 74-year-old man presented to the emergency department with slightly impaired consciousness (Glasgow Coma Scale (GCS): E3V5M6) after a fight while drinking alcohol. The next day, he developed a strong headache and gradually deteriorating consciousness (GCS: E3V4M6) with watery rhinorrhoea (see online supplementary vid...

Sixty-three fractures of the femur occurring in Paget’s disease of bone have been studied to elucidate the mechanism of fracture and to compare methods of treatment and results with those of other series. Although Paget’s disease is commonly symptomless, fracture, particularly of the femur, is one of the most frequent complications (Brailsford 1938, Lake 1951). Many small series offractures hav...

Figure 2. Extrusion after 1 week. A subgingivally fractured incisor presents a restorative challenge. Orthodontic eruption is a good alternative to crown lengthening for restoring the biological width, maintaining the alveolar bone, and restoring esthetics. The technique requires a hook to serve as the attachment system, fixed to the fractured tooth root, and an anchorage bar to allow movement ...

Successful fracture repair requires restoration of bone morphology and mechanical integrity. Recent evidence shows that fractured bones of neonatal mice undergo spontaneous realignment, dubbed "natural reduction." Here, we show that natural reduction is regulated by the proprioceptive system and improves with age. Comparison among mice of different ages revealed, surprisingly, that 3-month-old ...
