Purpose: To investigate whether epinephrine in irrigation fluid improves visual clarity in arthroscopic shoulder surgery.

Methods: We performed a systematic review and meta-analysis of randomized controlled trials (RCTs) that compared the surgical outcomes of patients who did and did not receive epinephrine during arthroscopic shoulder surgery. We searched the Cochrane Central Register of Controlled Trials, MEDLINE, and Embase for relevant RCTs.

This paper presents an experimental study conducted to investigate the effect of fiber reinforcement on the mechanical properties and shrinkage cracking of recycled fine aggregate concrete (RFAC) with two types of fiber-polyvinyl alcohol (PVA) and nylon. A small fiber volume fraction, such as 0.05% or 0.

Background: In daily practice, we discovered one of the secondary magnetic resonance (MR) findings of the subscapularis (SSC) tendon tear, the "bridging sign", which has not been previously described.

Purpose: To describe the "bridging sign" on shoulder MR imaging and its radiological and clinical significance in patients with SSC tendon tear.

Material And Methods: Twenty-nine patients who had undergone shoulder arthroscopy and had full-thickness tear of the subscapularis tendon were enrolled.

Background: Over 60 repair/reconstruction techniques have been described for the treatment of coracoclavicular (CC) ligament injuries.

Purpose: To report the functional and radiological outcomes of single-tunnel CC ligament reconstruction using autogenous semitendinosus tendon.

Study Design: Case series; Level of evidence, 4.

Objective: To compare the diagnostic value of indirect magnetic resonance arthrography (I-MRA) with that of direct MR arthrography (D-MRA) for labral tears, rotator cuff tears, and long head of biceps tendon (LHBT) tears using a 3-T MR unit.

Materials And Methods: Institutional review board approval was given; written informed consent was obtained from all patients. From November 2005 to June 2006, 19 patients (eight men and 11 women; mean age, 51 years) who had undergone both I-MRA and D-MRA underwent arthroscopic surgery.

Purpose: To compare the diagnostic accuracy of three-dimensional (3D) isotropic magnetic resonance (MR) arthrography with two-dimensional (2D) MR arthrography for the diagnosis of labral lesions of the shoulder performed by using a 3.0-T imager.

Materials And Methods: Institutional review board approval was given for this retrospective study and informed consent was waived.

Objective: The purpose of our study was to prospectively compare the diagnostic accuracy of 3D isotropic indirect MR arthrography with conventional sequences of indirect MR arthrography for the diagnosis of labral and rotator cuff lesions on a 3-T MR unit.

Subjects And Methods: Thirty-six consecutive patients who were scheduled for shoulder arthroscopic surgery at our institution underwent indirect MR arthrography. Both conventional sequences and an additional 3D isotropic sequence were obtained 1 day before arthroscopic surgery.

Meningioma en plaque (MEP) is a rare tumor characterized more by its clinical and biological behavior than its histological appearance. Hyperostosis of the skull is one of the characteristic signs of MEP. This bony change can produce clinical symptoms and signs in MEP by pressing against adjacent structures.

Purpose: The purpose of this article is to report a new clinical entity of posterior instability of the shoulder and the results of its treatment.

Type Of Study: Case series.

Methods: The Kim's lesion, which is an incomplete and concealed avulsion of the posteroinferior labrum, was arthroscopically identified in 15 patients who presented with posterior or multidirectional posteroinferior instability.

Background: The purpose of this study was to evaluate the results of arthroscopic treatment of traumatic unidirectional recurrent posterior subluxation of the shoulder.

Methods: We treated twenty-seven patients who had traumatic unidirectional recurrent posterior subluxation of the shoulder with arthroscopic labral repair and posterior capsular shift, and we evaluated them at a mean of thirty-nine months postoperatively. Patients who had posteroinferior instability, multidirectional instability, or an atraumatic onset or who were undergoing revision were excluded.
