Management of bow legs in children: A primary care protocol.
Objective To reduce unnecessary orthopedic referrals by developing a protocol for managing physiologic bow legs in the primary care environment through the use of a noninvasive technique that simultaneously tracks normal varus progression and screens for potential pathologic bowing requiring an orthopedic referral. Methods Retrospective study of 155 patients with physiologic genu varum and 10...
متن کاملAdvances in growth plate modulation for lower extremity malalignment (knock knees and bow legs).
PURPOSE OF REVIEW Lower extremity angular deformities are among the most common nontraumatic conditions in children being referred to pediatric orthopedists. Understanding of this abnormality is essential for pediatricians and primary caregivers. There is a development in the surgical management of these problems that has improved the quality of care of affected children and adolescents. RECE...
متن کاملViolin bow vibrations.
The modal frequencies and bending mode shapes of a freely supported tapered violin bow are investigated by finite element analysis and direct measurement, with and without tensioned bow hair. Such computations are used with analytic models to model the admittance presented to the stretched bow hairs at the ends of the bow and to the string at the point of contact with the bow. Finite element co...
متن کاملThe Social Bow Tie
Understanding tie strength in social networks, and the factors that influence it, have received much attention in a myriad of disciplines for decades. Several models incorporating indicators of tie strength have been proposed and used to quantify relationships in social networks, and a standard set of structural network metrics have been applied to predominantly online social media sites to pre...
متن کاملModelling Non-axisymmetric Bow Shocks
I present an extension of the thin layer approximation to non-axisymmetric bow shocks. By choosing a suitable set of curvilinear coordinates that matches the geometry of a generally distorted bow shock surface, I derive the fluid equations for the flow. Analytical expansions are given for the matter flow near the bow shock stagnation point. Numerical solutions are also obtained, by using a revi...
