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.
Predicting the need for collateral ligament repair in transolecranon fractures of the elbow: a traffic light model
Biomechanical studies have shown translation of the proximal radius relative to the capitellum in the sagittal plane can predict integrity of the collateral ligaments in a transolecranon fracture model; no studies have examined this in clinical practice.
An Overview of Shoulder Blade Pain
Shoulder blade pain can have many different causes. Although you may assume you sustained an injury or simply slept in the wrong way, the pain might actually be related to your heart, lungs, spine, abdomen, or pelvis. In cases like these, the pain may be referred, meaning that a problem in one part of the body excites nerves that trigger pain in another part of the body, such as your shoulder blade.
What foods can help with carpal tunnel?
While there are specific treatment options for carpal tunnel syndrome (CTS), dietary changes are gaining attention. For example, foods that reduce inflammation may help CTS symptoms.
Shoulder Dislocation Symptoms and Treatment
A shoulder dislocation is an injury that occurs when the ball of the ball-and-socket shoulder joint is separated from its normal position. The ball comes out of the socket of the shoulder. When this occurs, the ball may stay out of the shoulder and need to be put back into place, or it can slide back into normal position on its own.
Treatment Options for Calcific Tendonitis of the Shoulder
Calcific tendonitis is a common source of shoulder pain and can be a frustration given the severity of pain and the duration of symptoms. However, the news is not all bad! On a positive note, the vast majority of patients do find relief with nonsurgical treatments for this condition. In fact, studies have shown about 75 percent success with simple steps for treatment. While treatment often takes 3 to 6 months, there are typically improvements without having to undergo a surgical procedure.
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.
How Depression Affects Hand And Arm Symptoms
Studies have shown that 1 in 8 patients who see a hand surgeon have symptoms of depression. This means that many patients can have hand issues and depression at the same time.
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.
Repetitive Pitching Decreases the Elbow Valgus Stability Provided by the Flexor-Pronator Mass: The Effects of Repetitive Pitching on Elbow Valgus Stability
Baseball pitching induces a large elbow valgus load, stressing the ulnar collateral ligament. Flexor-pronator mass contraction contributes to valgus stability; however, repetitive baseball pitching may weaken the flexor-pronator mass contractile function. The present study investigated the effects of repetitive baseball pitching on the medial valgus stability measured using ultrasonography.
