We conducted a retrospective study to investigate the effect of femoral bowing on the placement of components in total knee replacement (TKR), with regard to its effect on reestablishing the correct mechanical axis, as we hypothesised that computer-assisted total knee replacement (CAS-TKR) would produce more accurate alignment than conventional TKR. Between January 2006 and December 2009, 212 p...

Congenital bowing of many long bones in a single individual is comparatively rare and Angle (1954), in a review of the English literature, found only eight reported cases. On the other hand, bowing of individual long bones occurs with greater frequency, the same author reviewing 12 cases of anterior and 14 cases of posterior tibial angulation and three cases with bilateral involvement of the fe...

A skilled string performer is able to play a series of spiccato notes (short strokes played by a bouncing bow) with each onset showing little or no aperiodic motion before a regular slip/stick pattern (Helmholtz motion) is triggered. Kinematic analysis reveals that a well-behaving bow gives nearly vertical impacts on the string, and that the first slip of each note takes place when the normal b...

We present an experimental study on articulation in bowed strings, that provides important elements for a discussion about sound synthesis control. The study focuses on bow acceleration profiles and transient noises, measured for different players for the bowing techniques detaché and martelé. We found that maximum profiles of these profiles are not synchronous, and temporal shifts are dependan...

The treatment of anterolateral bowing with an intact tibia is directed toward prevention of the fracture and subsequent pseudoarthrosis. Patients with anterolateral bowing of the tibia are usually treated with an ankle-foot orthosis until the deformity is improved. There is no documentation that an orthosis can prevent the fracture or correct the deformity, and if the deformity is not corrected...

OBJECTIVE To determine factors affecting actual inguinal ligament course in live human subjects. INTRODUCTION AND HYPOTHESIS Although the expected inguinal ligament course is supposedly a straight line extending from anterior superior iliac spine to pubic tubercle, the actual inguinal ligament course is frequently depicted a priori by a downward bowing dotted line. There are no studies in a l...

The variety of echographic features associated with the mitral valve prolapse syndrome (MVPS) is not yet completely understood. Therefore, ultrasound recordings were obtained in 33 patients in whom mitral prolapse had been documented by biplane left ventricular cineangiography. Echographic abnormailities of the mitral leaflets during systole were recorded in 26/27 MVPS patients and 6/6 with rup...

The study of bowing is critically important for string players. Traditional bowing annotations are a valuable part of orchestral and individual documentation, but they do not help the performer to search a piece for other passages that should be bowed the same way, or to identify alternative bowing styles. We introduce a notation based on regular expressions that describes patterns of notes in ...
