ANTEGRADE NAILING VERSUS LOCKING PLATE OF 2-AND 3-PART PROXIMAL HUMERUS FRACTURES.

Objective: To evaluate and compare the proportions of complications and radiographic findings of osteosynthesis of 2- and 3-part proximal humerus fractures with two methods of treatment: third-generation antegrade nailing and locking plate.

Methods: 46 patients with a mean age of 58.9 ± 16.

Influence of the glenoid track and glenoid bone loss on the apprehension test for shoulder instability.

Background: The investigation of Hill-Sachs and bony Bankart lesions continues to evolve. Patients with large bone lesions can present with a positive apprehension test even at ranges below 45° of abduction and external rotation of the shoulder. Modern concepts, such as glenoid track and quantification of glenoid bone loss, have been increasingly applied to shoulder instability.

Evaluation of the Glenoid Track Tomographic Method in Magnetic Resonance Imaging/Arthro-MRI.

 To evaluate and compare the glenoid track method in 3D-reconstructed computed tomography (3D-CT) scans with magnetic resonance imaging (MRI) and/or arthro-MRI.  Forty-four shoulders with clinical and radiographic diagnosis of traumatic anterior instability were assessed using 3D-CT, MRI, and/or arthro-MRI scans. Glenoid track (GT), Hill-Sachs interval (HSI), and glenoid bone loss (GBL) were determined by a radiologist using 3D-CT images, and classified as on-track/off-track.
