The city of Malm#{246}has about 220,000 inhabitants, and more than 99 per cent of all the children are born in the city’s one obstetrical department. Since 1952 the routine paediatric examination, performed within two days and again seven days after birth, has included the hip joints. The well known snapping or clicking phenomenon of the hip has been regarded as a symptom of congenital dislocat...

Inertial sensors have gained relevance as wearable to acquire the kinematics of human limbs through fusion sensor algorithms and biomechanical models. However, there are some limitations use Measurement Units in control robotic devices: 1) Some approaches magnetometer readings estimate orientation sensor, and, a result, they prone errors due electromagnetic interferences; 2) Biomechanical model...

abstract background: osteoporosis is a major public health threat, and hip fracture is a serious consequence of osteoporosis. apatient with an osteoporosis-related hip fracture has an increased risk for a second hip fracture. the effect of osteoporosis management on the risk of recurrent hip fracture was evaluated in this study. methods: 58 hip fracture patients older than 50yr and bmd < 2.5 we...

The Turing reaction-diffusion model explains how identical cells can self-organize to form spatial patterns. It has been suggested that extracellular signaling molecules with different diffusion coefficients underlie this model, but the contribution of cell-autonomous signaling components is largely unknown. We developed an automated mathematical analysis to derive a catalog of realistic Turing...

conclusions a neglected hip dislocation with acetabular fracture can be managed satisfactorily with uncemented thr. bone reconstruction using chunk grafts and use of cementless components ensures long-term survival and also preserves adequate bone stock for revision, especially in young patients. introduction posterior hip dislocation of the hip with acetabular fracture is a challenging problem...

We have compared the energy expenditure during walking in three patients, aged between 51 and 55 years, with unilateral disarticulation of the hip when using the mechanical-controlled stance-phase control knee (Otto Bock 3R15) and the microprocessor-controlled pneumatic swing-phase control knee (Intelligent Prosthesis, IP). All had an endoskeletal hip disarticulation prosthesis with an Otto Boc...

Several investigators have pointed out that electron and neutron contamination from high-energy photon beams are clinically important. The aim of this study is to assess electron and neutron contamination production by various prostheses in a high-energy photon beam of a medical linac. A 15 MV Siemens PRIMUS linac was simulated by MCNPX Monte Carlo (MC) code and the results of percentage depth ...

The distribution, pharmacology and function of the arginine vasopressin (Avp) 1b receptor subtype (Avpr1b) has proved more challenging to investigate compared to other members of the Avp receptor family. Avp is increasingly recognised as an important modulator of the hypothalamic-pituitary-adrenal (HPA) axis, an action mediated by the Avpr1b present on anterior pituitary corticotrophs. The Avpr...

BACKGROUND The purpose of this study was to investigate the stability of dual-taper modular implants following impaction forces delivered at varying locations as measured by the distraction forces required to disassemble the components. METHODS Distraction of the head-neck and neck-stem (NS) tapers of dual-taper modular implants with 0°, 8°, and 15° neck angles were measured utilizing a custo...

BACKGROUND In the running community, a forefoot strike (FFS) pattern is increasingly preferred compared with a rearfoot strike (RFS) pattern. However, it has not been fully understood which strike pattern may better reduce adverse joint forces within the different joints of the lower extremity. PURPOSE To analyze the 3-dimensional (3D) stress pattern in the ankle, knee, and hip joint in runne...
