In this paper, we first introduce some new Morrey-type spaces containing generalized Morrey space and weighted Morrey space with two weights as special cases. Then we give the weighted strong type and weak type estimates for fractional integral operators [Formula: see text] in these new Morrey-type spaces. Furthermore, the weighted strong type estimate and endpoint estimate of linear commutator...

In this paper we give new characterization of the classical Morrey space. Complementary global Morrey-type spaces are introduced. It is proved that for particular values of parameters these spaces give new pre-dual space of the classical Morrey space. We also show that our new pre-dual space of the Morrey space coincides with known pre-dual spaces.

Objective To evaluate the functional and radiographic results of patients who underwent surgical treatment for terrible triad-type elbow injuries (TTE). Methods We retrospectively evaluated 20 patients, including one case with bilateral injuries (total of 21 elbows) that were surgically treated from January 2004 to July 2014. We evaluated the functional results of treatment by measuring the r...

BACKGROUND The purpose of this study is to retrospectively evaluate the clinical outcomes of 18 patients with large coronal shear fractures of the capitellum and lateral trochlea that underwent open reduction and internal fixation with headless compression screws. METHODS Eighteen patients were identified (16 women, 2 men) with an average age of 45 years and an average follow-up of 26 months....

BACKGROUND In patients managed with plate fixation for the treatment of an olecranon fracture, the placement of an axial intramedullary screw may obstruct the placement of bicortical screws in the ulnar shaft. To overcome this problem, unicortical screws can be applied with use of a contoured locking compression plate. The present study was designed to assess the effectiveness of this fixation ...

OBJECTIVE Terrible triad injury of the elbow (TTIE), comprising elbow dislocation with radial head and coronoid process fracture, is notoriously challenging to treat and has typically been associated with complications and poor outcomes. The objective of this systematic review was to summarize the most recent available evidence regarding functional outcomes and complications following surgical ...

BACKGROUND The aim of this study was to compare radial head prosthesis replacement with open reduction and internal fixation (ORIF) in the surgical treatment of Mason type III radial head fractures in 72 elderly patients. MATERIAL/METHODS Seventy-two elderly patients (mean age, 67.1±1.25 years, range, 62-81 years) with Mason type III radial head fractures were treated from January 2001 to Jun...

Between 1993 and 1999, we treated ten patients with comminuted fractures of the olecranon by multiple tension-band wiring and a graft from the iliac crest. Their mean age was 35 years (19 to 56). The mean follow-up was for 28.5 months (15 to 46) and the mean time to union of the fractures was four months (3 to 7). No patient reported difficulties with activities of daily living or symptoms of i...

Les fracture-luxations transolécraniennes sont une entité rare des fracture-luxations du coude. Il s'agit d'une lésion complexe qui peut compromettre le pronostic fonctionnel du coude. Dix patients étaient diagnostiqués dans notre service entre janvier 2005 et novembre 2012. Tous nos patients étaient de sexe masculin, l'âge moyen était de 29 ans. Les fractures de l'olécrane étaient complexes et...

This study aimed to explore the clinical effect of the coronoid process fractures with anteromedial approach. 18 cases of coronoid process fractures treated with the anteromedial approach were enrolled. Causes of injury included traffic injuries in 3 cases and fall on the ground in 15 cases. There were 6 cases of type I, 10 cases of type II, and 2 cases of type III according to the O’Driscoll c...
