Calcific tendinitis of the shoulder in the Korean population: demographics and its relation with coexisting rotator cuff tear.

Background: To evaluate the demographics, clinical and radiographic features of calcific tendinitis of the shoulder in the Korean population, specifically focusing on the incidence of coexisting rotator cuff tear.

Methods: Between October 2014 and January 2015, we performed a prospective multicenter study with 506 patients from 11 training hospitals in Korea. We collected data of demographics and radiographic analysis based on simple radiographs, clinical assessments based on visual analog scale (VAS) and the American Shoulder Elbow Surgeons (ASES) score, and treatment modalities that are used currently.

Does a Partial Rotator Cuff Tear Affect Pitching Ability? Results From an MRI Study.

Background: Numerous studies have examined changes in the athletic performance of baseball pitchers after rotator cuff surgery. However, only a few studies have evaluated changes in athletic performance caused by partial rotator cuff tears that are not treated surgically.

Purpose: To examine the course of partial-thickness rotator cuff tears and its possible effect on the athletic performance of professional pitchers.

Does anchor insertion angle or placement of the suture anchor affect glenoid rim fracture occurrence after arthroscopic Bankart repair?

Background: The purposes were to compare the characteristics of 2 groups of patients who underwent revision Bankart repair with and without glenoid rim fractures and to examine risk factors for glenoid rim fractures.

Methods: We retrospectively analyzed 39 patients who needed revision surgery after arthroscopic Bankart repair and identified 19 patients with and 20 patients without glenoid rim fractures. The insertion angle of the suture anchor, anchor position on the glenoid, and demographic data were compared between the groups.

Does Anchor Placement on the Glenoid Affect Functional Outcome After Arthroscopic Bankart Repair?

Background: In arthroscopic Bankart repair, anchor positions can affect glenoid labral height and functional outcomes.

Purpose: To evaluate anchor placement on the glenoid during Bankart lesion repair and determine which placement would lead to better functional outcomes.

Study Design: Cohort study; Level of evidence, 3.

Bennett lesions in baseball players detected by magnetic resonance imaging: assessment of association factors.

Background: The purpose of this study was to evaluate the characteristics of Bennett lesions in baseball players compared with those without a Bennett lesion and to identify other possible factors associated with Bennett lesions on magnetic resonance imaging (MRI).

Methods: We investigated 388 male baseball players with a career >1 year. Demographic factors and a routine physical examination, including glenohumeral internal rotation difference, scapular dyskinesis, and various pathologic changes, were reviewed on MRI to identify relative factors for Bennett lesions.
