Scapular notching, erosion of the scapular neck related to impingement by the medial rim of the humeral cup during adduction, is a radiographic sign specific to reverse shoulder arthroplasty (RSA). Its clinical and radiological consequences remain unclear. QUESTIONS/
Therefore, we: (1) determined the incidence of notching in a large series, (2) described the natural history of notching, (3) determined whether notching is related to functional scores or (4) radiographic signs of failure, and (5) identified factors related to notch development. PATIENTS AND
We retrospectively reviewed 448 patients who underwent a Grammont-type RSA (461 shoulders) with a mean followup of 51 months (range, 24-206 months). RSA was implanted for cuff tear arthropathy or osteoarthritis with cuff deficiency. We assessed scapular notching using AP views standardized under fluoroscopy. Clinical assessment included Constant-Murley score and range of motion. Aside from notching, radiographic assessment included evaluation of humeral and glenoid radiolucent lines.
Notching occurred in 68% of cases. It appeared early, but its later evolution was variable. Notching was associated with followup, strength, passive and active elevation, humeral radiolucent lines, and glenoid lucent lines. It also correlated with a higher rate in patients with preoperative superior erosion.
Scapular notching is frequent, generally progresses, and is associated with deterioration of some clinical parameters and radiolucent lines. We believe the preoperative pattern of glenoid erosion is of particular importance due to its influence on the surgeon's glenoid preparation and base-plate positioning. It is crucial to avoid cranial position and superior tilt. LEVELS OF

Impingement after reverse shoulder arthroplasty (RSA) is believed to occur from repetitive contact in adduction between the humeral component and the inferior scapular pillar. The primary purpose of t...
Reverse shoulder arthroplasty (RSA) was designed for the treatment of elderly patients with cuff tear arthropathy. Because of its success, the indications for RSA have expanded beyond cuff tear arthro...
As the volume of shoulder arthroplasty procedures performed in the United States continues to increase, the predicted number of revision shoulder arthroplasties grows even higher. Conversion of failed...
The increase of shoulder replacements will lead to a higher revision rate of shoulder arthroplasties. The aim of this study is to evaluate the clinical results of revision surgery performed in our hos...
The sequelae of proximal humeral fractures can produce severe shoulder dysfunction. We assessed the results of reverse shoulder arthroplasty (RSA) for these complex problems.
The purpose of this study is to determine if stabilizing the scapula (shoulder blade) during a common shoulder stretch is more effective at improving shoulder range of motion than not stab...

The purpose of this study is to prospectively evaluate two FDA approved implant designs for the Tornier Reverse Shoulder arthroplasty. The small difference in design is the amount of offse...

Unilateral or bilateral pain of the shoulder. It is often caused by physical activities such as work or sports participation, but may also be pathologic in origin.
The application of drug preparations to the surfaces of the body, especially the skin (ADMINISTRATION, CUTANEOUS) or mucous membranes. This method of treatment is used to avoid systemic side effects when high doses are required at a localized area or as an alternative systemic administration route, to avoid hepatic processing for example.
A variation of the PCR technique in which cDNA is made from RNA via reverse transcription. The resultant cDNA is then amplified using standard PCR protocols.
DNA sequences that form the coding region for retroviral enzymes including reverse transcriptase, protease, and endonuclease/integrase. "pol" is short for polymerase, the enzyme class of reverse transcriptase.
A ribonuclease activity that is a component of the HIV REVERSE TRANSCRIPTASE. It removes the RNA strand of the RNA-DNA heteroduplex produced by reverse transcription. Once the RNA moiety is removed a double stranded DNA copy of the HIV RNA can be synthesized.
