Software simulations of changing offsets and thus soft tissue tension when revising anatomic to reverse total shoulder arthroplasty in convertible platform systems.

Background: Revision shoulder arthroplasty may involve the need to remove a well-fixed humeral stem. To avoid this, convertible platform systems have been introduced. The biomechanics of reverse total shoulder arthroplasty (rTSA) differs from anatomic shoulder arthroplasty (aTSA).

Shoulder proprioception following reverse total shoulder arthroplasty.

Unlabelled: Joint replacement affects the proprioception, as shown in knees, elbows, and shoulder studies.

Aim: The aim was to evaluate shoulder joint position sense (JPS) following reverse total shoulder arthroplasty (rTSA) for patients with cuff arthropathy.

Methods: Twenty-nine patients that underwent unilateral rTSA (19 females, 10 males) and 31 healthy volunteers evaluated for JPS of shoulder using a dedicated high accuracy electronic goniometer.

Do elderly patients gain as much benefit from arthroscopic rotator cuff repair as their younger peers?

Background: This study was conducted to ascertain whether patients aged older than 75 years achieve outcomes after arthroscopic rotator cuff repair comparable to younger patients.

Methods: Arthroscopic cuff repair was performed in 60 shoulders of 59 patients aged older than 75 years. A control group of 60 younger patients, matched for sex, tear size, and American Society of Anesthesiology Functional Classification grade were included.

The "Parachute" Technique: A Simple and Effective Single-Row Procedure to Achieve an Increased Contact Area Between the Cuff-Tendon and Its Footprint.

Many techniques of arthroscopic rotator cuff repair have been described. No significant differences in clinical outcomes or rerupture rates have been observed when comparing single-row with double-row methods. Not all single- and double-row repairs are the same.

The "Purse String" Procedure for Recurrent Anterior Glenohumeral Instability: A Simple Technique to Achieve Bankart Repair, Capsular Shift, and a Good Labral Bumper.

Failure of arthroscopic techniques in cases of recurrent anterior glenohumeral instability may result from inadequate treatment of capsular injury. The use of few anchors has been cited as a cause of failure in arthroscopic stabilization techniques. This applies to the use of the suture anchors as spot-welding points in conventional techniques.

Clinical factors that affect perceived quality of life in arthroscopic reconstruction for acromioclavicular joint dislocation.

Objective: To analyse the results of arthroscopic repair of acromioclavicular dislocation in terms of health-related quality of life.

Material And Method: Prospective study of patients with acromioclavicular dislocation Rockwood grade iii-v, treated arthroscopically with a mean follow up of 25.4 months.

Bilateral reverse total shoulder arthroplasty-functional outcome and activities of daily living.

Background: Reverse total shoulder arthroplasty (rTSA) has gained popularity in recent years, providing good shoulder elevation, yet less predictable rotations. Good rotations are crucial for performance of activities of daily living (ADLs), including personal hygiene. Concerns remain regarding bilateral rTSA over lack of rotations bilaterally and resultant difficulties with ADLs.

Reverse shoulder arthroplasty with a cementless short metaphyseal humeral implant without a stem: clinical and radiologic outcomes in prospective 2- to 7-year follow-up study.

Background: Reverse shoulder prostheses are increasingly used in recent years for treatment of glenohumeral arthropathy with deficient rotator cuff. Bone preservation is becoming a major goal in shoulder replacement surgery. Metaphyseal humeral components without a stem were developed to minimize bone resection and preserve bone.

Revision shoulder arthroplasty: does the stem really matter?

Background: The management of a failed shoulder arthroplasty represents a complex and difficult problem for the treating surgeon, with potential difficulties and complications that are related to the need to remove a well-fixed stem. The aim of this study is to compare the intraoperative complications, postoperative complications, and outcome of revisions from stemmed arthroplasties (STAs) with those from surface replacement arthroplasties (SRAs).

Methods: From 2005 to 2012, 40 consecutive revision shoulder arthroplasties were performed at our institute: 17 from STAs and 23 from SRAs.

Thoracoscapular Fusion for Winging of the Scapula with Screw Fixation for Fascioscapulohumeral Dystrophy (Modified Copeland-Howard Procedure).

Introduction: This article describes our technique of thoracoscapular fusion with screw fixation for treatment of winging of the scapula in patients with fascioscapulohumeral dystrophy.

Step 1 Preoperative Evaluation: Perform the Horwitz test.

Step 2 Position The Patient And Mark The Skin For The Operation: With the patient on a Montreal mattress, position the arms in 90° to 110° of elevation in the scapular plane and approximately 90° of external rotation and mark the skin.
