Dr. Chalmers is invited to speak at the Nice Shoulder Course in France
The high-flying Red Rocks will soon take the floor to start their 2018 season. They will compete at the top of their abilities on the vault, the balance beam, the uneven bars, and in floor routines. While they make it look easy, gymnastics is one of the most challenging sports out there. Injuries are common, especially to certain areas of the body.
Structural glenoid grafting during primary reverse total shoulder arthroplasty using humeral head autograft
Large glenoid bone defects in the setting of glenohumeral arthritis can present a challenge to the shoulder arthroplasty surgeon. The results of large structural autografting at the time of reverse total shoulder arthroplasty (RTSA) are relatively unknown.
Reasons for Retirement Following Ulnar Collateral Ligament Reconstruction Among Major League Baseball Pitchers
Ulnar collateral ligament reconstruction (UCLR) has become an increasingly common procedure among Major League Baseball (MLB) pitchers. The long-term effects of this procedure on the career of an MLB pitcher are largely unknown.
In cartoons a bulge in the bicep is the symbol of muscularity – and that someone has been eating their spinach. In real life though, such a bulge signals something very different – and it isn’t caused by muscles at all. “It’s the biceps tendon,” said Peter Chalmers, MD, an orthopedic surgeon with University of Utah Health. “When it tears that causes the muscle to slump leading to what’s known as the ‘Popeye sign.’”
Baseball Sports Medicine: Game-Changing Concepts
Are the hamstrings from the drive leg or landing leg more active in baseball pitchers? An electromyographic study
Ulnar collateral ligament reconstruction (UCLR) has become a common procedure among baseball players of all levels. There are several graft choices in performing UCLR, one of which is a hamstring (gracilis or semitendinosus) autograft. It is unclear whether the hamstring muscle from a pitcher's drive leg (ipsilateral side of the UCLR) or landing leg (contralateral side of the UCLR) is more active during the pitching motion. We hypothesized that the landing leg semitendinosus will be more electromyographically active than the drive leg.
Continuous interscalene brachial plexus blockade is associated with reduced length of stay after shoulder arthroplasty
Catheter-delivered continuous interscalene anesthesia has demonstrated improved pain control in randomized clinical trials. The purpose of this study is to determine whether the introduction of continuous catheter anesthesia was associated with a change in length of stay (LOS), readmission, rates of discharge home without home health or nursing services, or opioid administration. We hypothesized that the introduction of continuous catheter anesthesia would be associated with a decrease in LOS, readmission, non-home discharge, and opioid administration.

Angled BIO-RSA (bony-increased offset–reverse shoulder arthroplasty): a solution for the management of glenoid bone loss and erosion
Glenoid deficiency and erosion (excessive retroversion/inclination) must be corrected in reverse shoulder arthroplasty (RSA) to avoid prosthetic notching or instability and to maximize function, range of motion, and prosthesis longevity. This study reports the results of RSA with an angled, autologous glenoid graft harvested from the humerus (angled BIO-RSA).
