THE MORPHOMETRY OF THE CORACOID PROCESS - ITS AETHIOLOGIC ROLE IN THE SUBCORACOID IMPINGEMENT SYNDROME

Abstract: Anatomical morphometric studies of the coracoid process and coraco-glenoid space were carried out on 204 dry scapulae. No statistically significant correlations were found between length, or thickness of the coracoid process, prominence of the coracoid tip, coracoid slope, coraco-glenoid distance, or position of the coracoid tip with respect to the uppermost point of the glenoid. These anatomical characteristics were independent. of the dimensions of the scapulae. Three configurations of the coraco-glenoid space were identified. Type I configuration was found in 45% of scapulae and Type II and Type III, in 34% and 21% of specimens, respectively. The lowest value of the coraco-glenoid distance were seen in Type I scapulae. Morphometric characteristics which might predispose to subcoracoid impingement were found in 4% of Type I scapulae. A total of 27 scapulae, nine with each type of configuration were submitted to CT scanning. Scapulae with a Type I configuration were found to have low values for the coraco-glenoid angle and coracoid overlap, which are known to be associated with a short coraco-humeral distance. Subjects with a Type I configuration, and severe narrowing of the coraco-glenoid space, appear to be predisposed to coraco-humeral impingement. These morphometric characteristics may be easily evaluated on CT scans

Semilinear equations with exponential nonlinearity and measure data

We study the existence and non-existence of solutions of the problem [GRAPHICS] where Omega is a bounded domain in R-N, N >=, 3, and it is a Radon measure. We prove that if it 4 pi HN-2, then (0.1) has a unique solution. We also show that the constant 4 pi in this condition cannot be improved. (c) 2005 Elsevier SAS. All rights reserved

Foreign Policy and the Ideology of Post-ideology: The Case of Matteo Renzi’s Partito Democratico

The post-communist Italian Left has experienced a long phase of ideational misalignment between ideas placed at different levels, as a qualified discursive institutionalist approach demonstrates. Background public philosophies have often clashed with post-communist political ideology, while foreign policy programmes have often contradicted specific policies. Under the leadership of Matteo Renzi, however, the PD is now experiencing a moment of remarkable ideational consistency. Rather than being founded on entirely new premises, this new consensus folds old elements into new ones and shows all the defining traits of post-ideology. Yet, by espousing post-ideology, Renzi is making an ultimately ideological move whose limitations may soon start to show

Very singular solutions for linear Dirichlet problems with singular convection terms

We study the existence of distributional solutions for the boundary value problems (1.1) and (1.2) if E does not belong to LN, namely [Formula presented], A∈R. The size of A plays an important role: if α(N−2)≤|A

A weak minima approach to the study of the existence of saddle points of integral functionals

We study of the existence of saddle points of the functional [Formula presented] defined in (1.1) both in the regular case, i.e., if [Formula presented] belongs to [Formula presented], and in the singular one, i.e., if [Formula presented] belongs to [Formula presented]

Existence Results for a System of Kirchhoff–Schrödinger–Maxwell Equations

In this paper, we study existence, nonexistence, and properties of solutions for some Kirchhoff–Schrödinger–Maxwell systems as (1.3). The solutions can be seen as saddle points of functionals which are unbounded both from above and from below

A consequence of Djairo’s Lectures on the Ekeland variational principle

In this paper we prove that if a functional has bounded minimum u, then is is possible, using Ekeland’s ε-variational principle, to build a minimizing sequence which is uniformly convergent to u

Uniformly elliptic Liouville type equations: Concentration compactness and a priori estimates (Communications on Pure and Applied Analysis (2005) 4 (499-522))

We analyze the singular behavior of the Green’s function for uni- formly elliptic equations on smooth and bounded two dimensional domains

A semilinear system of Schrödinger–Maxwell equations

In this paper we are going to prove existence and regularity results for positive solutions of the following elliptic system: −div(M(x)∇u)+rφur−1=f+φr,−div(M(x)∇φ)+ruφr−1=ur.where Ω is a bounded open subset of RN, M is a bounded, uniformly elliptic matrix, r>1, and f≥0 belongs to some Lebesgue space Lm(Ω), with m≥1. We will also prove the relationships of the solutions of the system with saddle points of the integral functional [Formula presented
