Survivors of infantile meningococcal septicaemia often develop progressive skeletal deformity as a result of physeal damage at many sites, particularly in the lower limb. Distal tibial physeal arrest typically occurs with sparing of the distal fibular physis leading to a rapidly progressive varus deformity. There have been reports of isolated cases of this deformity, but to our knowledge there ...

BACKGROUND A triad of deformities-thoracolumbar scoliosis, pelvic obliquity, and femoral head (hip) subluxation/dislocation-occurs frequently in non-ambulatory neuromuscular patients, but their close inter-relationship is infrequently appreciated or quantified. We propose a deformity documentation approach to assess each component simultaneously. METHODS The documentation assesses each compon...

Methods The following were used in the evaluation: Bad Sobernheim Stress Questionnaire (Brace and Deformity), Trunk Appearance Perception Scale (TAPS), and Knee – Feet Perception Scale (KFPS). The BSSQ Brace estimates the stress scoliosis patients have whilst wearing brace, the BSSQ Deformity estimates the stress involved with body deformation. Minimal points number equals 0 (the greatest stres...

STUDY DESIGN Descriptive study of the Scoliosis Research Society (SRS) Classification for Adult Spinal Deformity using interobserver reliability measures for validation of the system. OBJECTIVES To propose and validate a classification system for adult spinal deformity that will have utility in reporting on treatment options and outcomes for affected adults. SUMMARY OF BACKGROUND DATA Class...

Popcorn noise is a large transient noise spike at the reader shortly after writing due to unstable domains in writer yoke. The popcorn noise was found to dependent on write frequency. It is firstly reported that the popcorn noise occurred by the write instability of shielded-single-pole head (SSPH) can be captured in row-bar level QST which is experimentally confirmed. Thus, a PMR head can be r...

The article presents a new method of counteracting shaft voltages and currents in AC electrical machines. It is based on the use an auxiliary winding located stator machine. design test stand adapted to measurement machine, prototype synchronous machine with permanent magnets, has been presented. model was used conduct number laboratory tests aimed at confirming functionality various operating ...

Permanent magnet synchronous motors (PMSMs) are highly affected by magnetization, which determines the magnetization level in permanent (PM). There three main methods: single-unit, stator coil, and post-assembly magnetization. Post-assembly is widely used PMSM mass production due to its ability achieve high performance using a separate magnetizing yoke. However, spoke-type PMSMs with ferrite PM...

When the uniformity of magnetization yoke is low, a mismatch occurs between physical rotation center and due to magnetic force after magnetization. This discrepancy in can cause issues such as vibration noise during high-speed rotation, which long term leads decrease lifespan motor. In addition, order minimize problem motor when vehicle used for more than 10 years purchase, problems caused by s...

Total hip arthroplasty (THA) in proximal femoral deformity represents a relatively uncommon challenge. Proximal femoral deformity is classified depending on the etiology and location and geometry of the deformity. Classification by etiology includes developmental processes, previous trauma, or previous surgery (osteotomy or THA). The latter, previous surgery, is the most common cause of femoral...
