Bony Increased Offset-Reversed Shoulder Arthroplasty (BIO-RSA).

Introduction: Bony increased offset-reversed shoulder arthroplasty (BIO-RSA) is an effective and safe means of achieving lateralization of the prosthetic center of rotation in reverse shoulder arthroplasty.

Step 1 Preoperative Planning: Confirm the indication for surgery and obtain radiographs and 3-dimensional (3D) imaging (computed tomography [CT] or magnetic resonance imaging [MRI] scans) to confirm the suitability for a BIO-RSA.

Step 2 Patient Positioning And Surgical Approach Video 1: With the patient in the beach-chair position, approach the shoulder via a standard deltopectoral approach.

Metal-backed glenoid implant with polyethylene insert is not a viable long-term therapeutic option.

Background: The aims of this study were to determine the survival of anatomic total shoulder arthroplasty with uncemented metal-backed (MB) glenoid components with a polyethylene (PE) insert in primary osteoarthritis, to assess the reasons for revision surgery, and to identify patients and diagnostic factors that influence failure rates.

Methods: Between 1994 and 1999, 165 patients (mean age, 68 years) with primary osteoarthritis were treated with anatomic total shoulder arthroplasty using an uncemented MB/PE glenoid component. Outcomes were assessed both clinically and radiologically with a minimum of 2 years of follow-up.

Revision surgery of reverse shoulder arthroplasty.

Background: There is limited knowledge regarding revision of reverse shoulder arthroplasty (RSA). This study assesses reasons for failure in RSA and evaluates the outcomes of revision RSA.

Materials And Methods: Between 1997 and 2009, 37 patients with RSA had revision surgery.

Prognostic factors and limitations of anatomic shoulder arthroplasty for the treatment of posttraumatic cephalic collapse or necrosis (type-1 proximal humeral fracture sequelae).

Background: The aim of this study was to evaluate the prognostic factors and limitations of anatomic unconstrained shoulder arthroplasty, performed without tuberosity osteotomy, for the treatment of secondary glenohumeral arthritis following posttraumatic cephalic collapse or necrosis of the humeral head, defined as type-1 fracture sequelae.

Methods: Fifty-five patients with type-1 fracture sequelae treated with anatomic shoulder arthroplasty were included in this retrospective single-center cohort study. All anatomic humeral prostheses were implanted without performing a greater tuberosity osteotomy.

Bony increased-offset reversed shoulder arthroplasty: minimizing scapular impingement while maximizing glenoid fixation.

Background: Scapular notching, prosthetic instability, limited shoulder rotation and loss of shoulder contour are associated with conventional medialized design reverse shoulder arthroplasty. Prosthetic (ie, metallic) lateralization increases torque at the baseplate-glenoid interface potentially leading to failure.

Questions/purposes: We asked whether bony lateralization of reverse shoulder arthroplasty would avoid the problems caused by humeral medialization without increasing torque or shear force applied to the glenoid component.

Detection of occult wrist fractures by quantitative radioscintigraphy: a prospective study on selected patients.

Objective: To determine the value of quantitative radioscintigraphy (QRS) in the diagnosis of wrist trauma occult fractures.

Purpose: Because of the risk of non-union, the diagnosis of wrist fractures, including scaphoid fractures, is essential but remains difficult despite many imaging modalities. The aim of the study was to assess the benefits of QRS in the diagnosis of occult post-trauma wrist fractures.

Ectopic insertion of the pectoralis minor: implication in the arthroscopic treatment of shoulder stiffness.

Although ectopic insertion of the pectoralis minor has been previously described in the literature, the role of such anatomical variations in producing shoulder symptoms (i.e., pain and/or stiffness) remains controversial.
