Impact of Reverse Shoulder Arthroplasty Design and Patient Shoulder Size on Moment Arms and Muscle Fiber Lengths in Shoulder Abductors
Reverse shoulder arthroplasty (RSA) increases the moment arm of the deltoid, however there is limited knowledge on the accompanying changes in muscle architecture that play a role in muscle force production. The purpose of our study is to use a geometric shoulder model to evaluate the anterior deltoid, middle deltoid, and supraspinatus regarding 1) differences in moment arms and muscle-tendon lengths in small, medium, and large native shoulders, and 2) impact of three RSA designs on moment arms, muscle fiber lengths, and force-length (F-L) curves.
Orthobiologics: An Updated Definition
Orthobiologics is a subset of regenerative medicine, which focuses on treating the musculoskeletal system. The main therapeutics utilized include platelet-rich plasma, stem cells, exosomes, and scaffolding matrices. Continuous discoveries and new innovations have led to an increase in both popularity and usage of these therapeutics by various medical and scientific communities.
5 Long-Term Problems After Meniscus Surgery
Although arthroscopic surgery of the meniscus is minimally invasive, you may still experience knee pain after surgery. For some people, other problems can occur after surgery, such as arthritis, re-injury, incomplete rehabilitation, and more.
Common to Serious Arm Pain Causes
Arm pain can be in the upper or lower arm. You may feel arm pain on the outside of your shoulder. Arm pain can also travel further down the arm toward the elbow.
Isolated Primary Latarjet Procedures for Anterior Shoulder Instability Results in High Rates of Graft Resorption and Glenohumeral Degenerative Changes with Low Rates of Failure at a Minimum 2-Year Follow-Up: A Systematic Review
To evaluate the incidence of postoperative complications after an isolated primary Latarjet procedure for anterior shoulder instability at a minimum 2-year follow-up.
