This means we spent a lot of time refining our report to be as readable and comprehensible as possible. The approach mn and the release are divided into the throwing phases shown in table 1. While the prototypical throwing athlete in the United States is a baseball player, many athletes use similar motions, including softball players, American football quarterbacks, javelin throwers, cricket bowlers, and water polo players. ex: pushing heavy doors, bench press, push-ups. Understanding the elbow anatomy is vital for differential diagnosis within the joint. Occurs in the overhead athlete or throwing athlete as a result of chronic overuse ... Biomechanics.

Elbow Injuries in the Throwing Athlete High valgus and extension loads imparted to the athleteâs elbow during repetitive overhead throwing can lead to acute and chronic pathology. Professional Athletes / Olympians. In the throwing athlete who continues the repetitive, throwing motion despite valgus laxity from ulnar collateral ligament insufficiency, the authors believe that these results provide a plausible mechanism for injury throughout the entire throwing motion secondary to ulnohumeral chondral and ligamentous overload. Olecranon Stress Fracture . 5 th Annual San Francisco Giants Sports Medicine Conference. Operative Techniques in Sports Medicine. Biomechanics of the elbow in tennis. Sports Health 2009;1(2):108â120. A basic understanding of biomechanics of tennis and analysis of the forces, loads and motions of the elbow during tennis will improve the understanding of the pathophysiology of these injuries. Injuries to the throwing elbow and shoulder are common among youth baseball athletes.1 Collins and Comstock2 reported an estimated 131 555 injuries were sustained during the 2005â2006 and 2006â2007 academic years in high school play alone. The stress of repetitive throwing does predispose athletes to certain conditions with which treating clinicians need to be familiar. Disclosure Neither I, Jonathan Santana DO, nor any of my family members have any relevant financial relationships to be discussed, directly or indirectly, referred to or illustrated with or without recognition with the presentation. The forces generated in the various phases of the throwing arc are distributed through the soft tissue and bone of the elbow joint. These processes setup youth pitchers to sustain throwing injuries at their shoulder and elbow in ways that differ from their adult counterparts. Anatomically, the UCL functions as a soft tissue restraint that stabilizes the elbow joint from valgus stress associated with the throwing motion (3, 5). 1998 Mar;27(3):187-8. Most commonly associated with throwing sports such as baseball and softball, medial sided elbow pathology is due to repetitive valgus stress on the medial stabilizers of the elbow.

Elbow Biomechanics and Rehab of the Overhead Throwing Athlete. The biomechanics of the windmill pitch places a large demand on the shoulder joint, This demand leads to increased flexion at the elbow joint leaving the shoulder structure vulnerable to chronic injuries. Arthroscopic surgery for the elbow in the throwing athlete has evolved and has proven successful results. In competitive events each athlete will throw four to sic times per competition. Adult phases of throwing and the forces generated in each phase are compared with the developmental phases of throwing in children. The pull begins in the final steps of the approach and is important to the development of young throwers (Valleala, 2009, p.16). Occurs in the overhead athlete or throwing athlete as a result of chronic overuse.

Sport Specific Population. The cameras were set-up on a rigid tripod and secured to the floor in the location. Extension at the elbow can be seen during a throwing action or tennis stroke. The athlete tries to achieve this objeetive, which is gen erally called the "maximization of throwing distance", via the following throwing elements: approach mn, re lease, braking (final phase), and the flight of the javelin. Baseball: Throwing Basic Biomechanics 1. BIOMECHANICS AND KINEMATICS To more thoroughly explore the causes and potential treatments for anterior elbow pain in the overhead athlete, a discussion of the throwing motion is warranted. Over time, normal soft tissue and bony stabilizing structures of the elbow undergo progressive structural changes and can succumb to injury.

Whiteley's review entitled: "Baseball throwing mechanics as they relate to pathology and performance - A review," does an exceptional job relating the biomechanics of throwing to physical therapy based on the research of over 100 articles. Medial sided elbow injuries fit under the umbrella term of âvalgus overload injuriesâ with the specific pathology dependent on the skeletal maturity of the athlete. Within the biomechanics reports, we obtain various kinematic metrics of the upper and lower body during the throwing motion. The most important aspects of the evaluation of the throwing athlete are the history and physical examination. The UCL is a complex com-posed of the anterior oblique, posterior oblique, and transverse ligaments. During overhead throwing, there are tremendous forces placed on the medial elbow that can result in injury to the ulnar nerve. Treatment / Technique Today, a wide array of less expensive, user-friendly platforms for 2D video analysis of the throwing athlete is available to the sports medicine clinician for assessing youth and adolescent throwing biomechanics. Most specific injuries of overhead throwing athletes occur at the shoulder and elbow. Medial elbow injuries, such as ulnar collateral ligament sprains, are often caused by excessive elbow valgus and shoulder external-rotation torques occurring during the late cocking phase of throwing. Arthro-scopic treatment includes debridement of posteromedial synovitis, loose-body removal, and excision of the olecra- non spur. The elbow joint is composed of 3 articulations: the proximal radioulnar joint, the ulnohumeral joint both anteromedially and posteriorly, and the radiocapitellar joint laterally.

The elbow is subjected to enormous valgus stresses during the throwing motion, which places the overhead-throwing athlete at considerable risk for injury. The â¦ Preventing throwing injuries. A basic understanding of biomechanics of tennis and analysis of the forces, loads and motions of the elbow during tennis will improve the understanding of the pathophysiology of these injuries. The throw is measured from where the tip touches the ground and it must land tip first within the 29 degree sector (Unknown, 2015). Throwing places unique demands on the elbow, resulting in predictable injury patterns. When throwing the shot, every part of the arm needs to be flexedand extended to get the best possible throw (Elbow). 8â16 At the glenohumeral joint, that external-rotation torque during the late cocking phase and distraction forces â¦ Throwing requires distraction forces on the inside of the elbow as the ball accelerates. Objectives â¢Review relevant elbow anatomy and throwing biomechanics â¢Discuss common elbow injuries and their treatment in throwing athletes â¢Understand risk factors and how to prevent elbow injuries in young throwers.

Then, we describe the background information, clinical presentation, imaging appearance, and treatment options for each specific injury. Overuse injuries in younger athletes are becoming more prevalent. Wind Up. The purpose of this article is to review the anatomy, biomechanics, and appropriate clinical care of an overhead throwing athlete suffering from injury to their ulnar nerve. Lintner D, Noonan TJ, Kibler WB. Significant advantages in recent arthroscopic surgical techniques and ligament reconstruction have markedly improved the prognosis for a healthy return to competition for the extremely motivated athlete. Crow Step-A Crow step is a quick side step, which is a quick âLeft Right, Leftâ (if throwing with right hand) The last step of the crow step is the during the throwing action.. Determining differences in pitching biomechanics becomes quite obvious when looking at the late cocking phase of throwing.
