Please check the hierarchy of the section headings and correct if necessary. Both of these conditions are treated initially with rest from throwing, followed by gradual return to throwing through an interval throwing program. The following chapter provides an overview of the relevant anatomy, biomechanics, and diagnosis of VEO. Single-assessment numeric evaluation (SANE), Oxford Elbow Score (OES), quickDASH (Disabilities of the Arm, Shoulder, Hand), patient satisfaction and post-operative range of motion were evaluated. There is no substitute for a careful clinical history and physical examination in not only establishing the diagnosis but ensuring that a complete diagnosis with its subsequent prognostic outcome can be rendered. The most common imaging manifestations of PMOI by CT or MRI include joint space narrowing, subchondral sclerosis, and osteophytes at the PMOS. Information quality depends on the search term used, website authorship, and commercial bias. Website quality and accuracy were lower with use of the search term "pitcher's elbow" as compared with "elbow ulnar collateral ligament injury" or "tommy john injury" (P ≤ .001). IAR INSTITUTE FOR ATHLETE REGENERATION References Miyashita K, Kobayashi H, Koshida S, Urabe Y. Glenohumeral, scapular, and thoracic angles at maximum shoulder external rotation in throwing. Before the first UCL reconstruction, performed by Frank Jobe in 1974, this injury was considered career ending in overhead athletes. The frequency of UCL reconstruction is steadily rising in New York State and becoming more common in adolescent athletes. The biomechanical findings of this study offer scientific feedback for developing methods used to minimize the effects of valgus load on pitching-related elbow injuries. Combined disorders as well as the direction and form of the fracture line were analyzed on plain radiographs, computed tomography, and magnetic resonance imaging. Our primary literature search yielded 1144 hits. Post-operative flexion was restrained in seven patients and extension in eight patients; 59% of patients reached full ROM at final follow-up. ConclusionsR-LCL plication produces subjective satisfaction and positive clinical results in patients presenting with a symptomatic minor instability of the lateral elbow (SMILE) at 2-year median follow-up. R-LCL plication was performed in the presence of at least one sign of lateral ligamentous patholaxity and one intra-articular abnormal finding. Introduction: valgus extension overload (posteromedial shock) is a type of injure that is relatively frequent in throwing athletes and may require surgical procedures to be performed so that the athlete can keep on competing. Ulnar collateral ligament (UCL) reconstruction is now being performed more commonly and on younger patients than in prior decades. The more commonly identified posterior osteophyte was present in all cases. Ulnar nerve entrapment can be a cause of elbow, wrist, and hand pain. You can request the full-text of this article directly from the authors on ResearchGate. The mean reading grade level was 10.7. The purpose of this study was to review a large group of patients who had arthroscopy of the elbow to determine the efficacy and relative risks of this procedure. Magnetic resonance imaging (MRI) is an excellent tool for the evaluation of joint pathology due to its high sensitivity as a result of high contrast resolution for soft tissues. The ligamentous, osseous, musculotendinous, and neural structures at the postero-medial side of the elbow are at risk for various injuries in overhead athletes. Throwing sports [4] -baseball is most common Overhead sports. After checking osteophyte size and location through 3-dimensional computed tomography, arthroscopic osteophyte resection was performed. Valgus torque at the elbow during baseball pitching is associated with 6 biomechanical variables of sequential body motion. Methods: In particular, valgus extension overload during the throw-ing motion can precipitate a cascade of chronic injuries that can be debilitating for both casual and high-perfor-mance athletes. valgus extension overload. VEO results from repetitive extreme valgus forces across the elbow and comprises a constellation of injuries located at the posteromedial compartment (osteophyte formation, olecranon stress fractures , and impingement), the ulnar … Before studying the treatment of these shoulder injuries, it is paramount that the health professional have an understanding of the etiology of and the underlying mechanisms for shoulder pathology. The condition is caused by a repetitive valgus force and medial laxity of the elbow leading to excessive shear forces and compression of the articulation between the posteromedial olecranon and the olecranon fossa (Fig. Am J Orthop 2016;45:144-151. However, the "weekend warrior" can sustain similar injuries and can have a similar desire to return to play as quickly as possible. Retrospectively, players with positive physical examination results associated with posterior elbow pain, defined as olecranon tenderness and/or a positive elbow extension impingement test, were selected. There was a statistically significant decrease in fastball accuracy after reconstruction, which was present up to 3 years postoperatively ( P = .007). After retrospectively reviewing the clinical records and imaging studies, 31 of the 47 players were diagnosed with PMOI by the criteria of posteromedial elbow pain with clinical consistency for PMOI and characteristic osteoarthrosis at the posteromedial ulnotrochlear articulation (posteromedial olecranon space, PMOS) detected by CT and/or MRI. Results: We present normal arthroscopic elbow joint anatomy with magnetic resonance imaging correlation. The purpose of this case study was to describe an innovative, multimodal approach to conservative management of a chronic UCL injury in a college-aged baseball pitcher. Doing so will allow radiologists to provide accurate interpretations that appropriately guide patient management. Systematic review. A thorough patient history and physical examination with appropriate diagnostic imaging is required to correctly identify the etiology of the elbow pain. Website readability was ascertained with the Flesch-Kincaid score. Removing the least amount of olecranon tip while still adequately addressing the impingement lesions may offer the lowest risk of overloading the ulnar collateral ligament. Conclusion: Athletes involved in sporting activities can suffer acute injuries or can develop overuse injuries that affect the elbow. Among baseball-related elbow disorders, the incidence of OSFs was 5.4%. The most common diagnoses were posteromedial olecranon osteophyte (65%), ulnar collateral ligament injury (25%), and ulnar neuritis (15%). The challenge in management of these injuries to the elbow, wrist, and hand is identifying those injuries that will benefit from early surgery compared with those that may be safely treated nonsurgically. Various posterior elbow problems cause posterior elbow pain among baseball players. Outcomes for ulnar collateral ligament reconstruction: A retrospective review using the KJOC assessment score with two-year follow-up in an overhead throwing population, Medial elbow pain in the overhead athlete, Arthroscopic Olecranon Osteophyte Resection in the Baseball Players with Elbow Valgus Extension Overload Syndrome, Overuse Upper Extremity Injuries in the Skeletally Immature Patient: Beyond Little League Shoulder and Elbow, Ulnar Collateral Ligament Injuries in the Throwing Athlete, The Biomechanics of Throwing: Simplified and Cogent, Prevalence of posterior elbow problems in Japanese high school baseball players, A 16-Year-Old Baseball Pitcher with a Sore Elbow, Imaging of the post-operative medial elbow in the overhead thrower: common and abnormal findings after ulnar collateral ligament reconstruction and ulnar nerve transposition, Non-operative management of ulnar collateral ligament injuries in the throwing athlete, Ulnar Collateral Ligament Injuries of the Elbow, Tratamiento quirúrgico del síndrome de sobrecarga en valgo y extensión en atletas, Intra-articular findings in symptomatic minor instability of the lateral elbow (SMILE), Arthroscopic R-LCL plication for symptomatic minor instability of the lateral elbow (SMILE), Multimodality Imaging of the Painful Elbow, Sports Injuries of the Hand, Wrist, and Elbow, Medial Elbow Injuries in the Throwing Athlete, Operative Strategies for Ulnar Collateral Ligament Insufficiency. Elbow pain in overhead sport athletes is not uncommon. The functional results according to Conway's scale were excellent in 5 patients, good in two and unsatisfactory in just one patient. Dry needling of both contractile and non-contractile tissue in combination with retraining of faulty mechanics may encourage chronically injured ligamentous tissue healing and encourage safe return to sport. ResearchGate has not been able to resolve any citations for this publication. The surgical procedure helps most of the athletes to come back to their normal sports activity. The term "high-level athlete" may include adolescents and high school students, collegiate athletes, and of course, the professional athlete. Elbow arthroscopy for treatment of valgus extension However, olecranon stress fractures can present a challenge from a management and a rehabilitation perspective owing to their vague presentation, thereby affecting how these patients are diagnosed and managed. The procedures were performed primarily by 7 different surgeons, using all 3 standard operating positions and a variety of arthroscopic portals. The average recovery period was 77 ± 47 days. All players returned to competitive sports activity levels within 77 ± 47 days. This study presents a new classification system for the different types of OSFs based on the origin and direction of the fracture plane. Results: Intraarticular loose bodies were found in 39% of the patients. The quality of medical information on the Internet has come under scrutiny. It further details the arthroscopic surgical technique to successfully treat patients with VEO. Ten cadaveric arms underwent posterior olecranon resection in 4-mm increments. Valgus extension overload (VEO) is a condition observed in overhead athletes that results from laxity of the ulnar collateral ligament (UCL). Abstract Injury to the medial collateral ligament of the elbow (MCL) can be a career-threatening injury for an overhead athlete without appropriate diagnosis and treatment. In contrast, bone marrow edema and associated soft tissue injuries in PMOI are more readily observed on MRI. In addition, there is some ambiguity in the literature, with the terms "olecranon spur" and "olecranon osteophyte" sometimes being used interchangeably. We aimed to determine the prevalence and diagnoses associated with posterior elbow problems and post-treatment recovery time for returning to sports in Japanese high school baseball players when treated in the off-season. The resulting articles were used to find other manuscripts pertaining to the subject. ... 12 Literature review demonstrated that the majority of the research involving PRP focuses on tendon repair and healing with significantly less evidence existing concerning the benefits of PRP injections for ligament healing. Due to the repetitive valgus stress overhead athletes place on their elbows, they are susceptible to common causes of medial elbow pain. This review presents the current knowledge about olecranon spur anatomy, pathophysiology, clinical presentation, diagnosis, treatment options and their outcomes, as well as clarification of the terms "spur" and "osteophyte". To establish a classification system for the different types of OSFs to improve diagnosis and clarify the onset mechanism. Mechanisms causing osseous disruption are of fairly high energy and can be quite disabling to the long-term career of the athlete. The act of overhead throwing is an eloquent full-body motion that requires tremendous coordination from the time of force generation to follow-through. Retrospective Case Report. Falls onto the outstretched hand, sudden loading, or direct trauma can result in elbow dislocation, fracture, or tendon rupture. Injuries to the shoulder and elbow in the pediatric and adolescent throwing athlete are common. Failure of. Despite an increase in the prevalence of medial ulnar collateral ligament (UCL) reconstruction of the elbow in professional baseball and popularity within the media, there are no population-based studies examining the incidence of UCL reconstruction. Study design: Author information: (1)American Sports Medicine Institute, 2660 10th Avenue South, Suite 505, Birmingham, AL 35205, USA. Results The minimal follow-up was 6 months and the maximum was 4 years, for a mean of 2.3 years. Valgus extension overload (VEO) is a syndrome of symptoms and physical findings commonly seen in overhead athletes because of an alteration in throwing biomechanics []. Surgical treatment of valgus extension overload is effective as advances in elbow arthroscopy instrumentation and technique continue to evolve. Medial ulnar collateral ligament (UCL) injuries have become increasingly prevalent in overhead athletes. Surgical excision of the posteromedial osteophyte through a relatively atraumatic posterolateral approach allowed early return of function without morbidity. To examine the epidemiological trends of UCL reconstruction on a statewide level over a 10-year period. Am J Sports Med. When mandated by the presence of a loose body or areas of cartilage wear in the anterior compartment, especially medially, a … We identified 56 pitchers with a total of 230,995 individual pitches for this study. Of the 5 studies reporting ERA, 2 cited a significant increase after UCLR, and 1 indicated a significant decrease. This review goes beyond describing the classic imaging findings of Little League shoulder and elbow and probes deeper into new insights suggesting a unifying etiology of metaphyseal or metaphyseal equivalent injury as the cause of many of the bony lesions described. This results in a variety of pathology at these different locations that can result in pain, mechanical symptoms, and loss of control/velocity, significantly limiting a pitcher’s participation in competitive baseball. Fourteen pitchers displayed a sidearm delivery and had significantly higher elbow valgus torques than did those with an overhand arm slot position. Resources on Valgus extension overload and related topics in OrthopaedicsOne spaces. Objective Conclusion: Specifically, impingement may occur between the olecranon and olecranon fossa due to high shear forces in the posterior elbow com… Treatment of VEO syndrome initiates with conservative measures like active rest, physiotherapy, and non-steroid anti-inflammatory medication but may require arthroscopy with osteophyte removal and medial corner olecranon osteotomy in refractory cases. In this article, we review indications and surgical setup for elbow arthroscopy. With a more detailed knowledge of the injury mechanisms and up-to-date treatment options for these patients, physicians will be able to prevent and better treat medial elbow pain in overhead athletes. Ulnar collateral ligament injuries, snapping triceps, medial epicondylitis, and ulnar nerve pathology are presented with key features of clinical exam, diagnostic tests, and current aspects of treatment. Appropriate expectations with regard to both treatment and the possible return to sports are critical in providing successful treatment for these often complex injuries. Whenever PMOI is diagnosed in the pitching elbow of a baseball player, CT should be considered prior to surgical intervention as it will often provide additional information to the surgeon that may alter surgical management. Further work is needed before definitive guidelines for olecranon osteotomy can be formulated. ... As many as 10% to 25% of active MLB pitchers report a history of UCL reconstruction, and there has been an estimated 10-fold increase in cases among professional players since 2000. The onset of trunk rotation, with other biomechanical variables that define sequential body motion, will significantly predict elbow valgus loading. We evaluated the clinical outcome after arthroscopic olecranon osteophyte resection without ligament operation in the elite baseball players who had valgus extension overload syndrome without moderate or severe medial collateral ligament injury. The primary purpose of this study was to determine the effects of UCL reconstruction on fastball accuracy, fastball velocity, and curveball movement in MLB pitchers. A systematic literature review, Return to Play and In-Game Performance Statistics Among Pitchers After Ulnar Collateral Ligament Reconstruction of the Elbow: A Systematic Review, Modified Jobe Approach With Docking Technique for Ulnar Collateral Ligament Reconstruction, Surgical treatment of valgus extension overload syndrome in athletes, Ulnar Collateral Ligament Evaluation and Diagnostics, Minimally Invasive Treatment of Valgus Extension Overload of the Elbow, Epidemiology of Medial Ulnar Collateral Ligament Reconstruction: A 10-Year Study of New York State, MRI–Arthroscopy Correlation of the Wrist: A Primer for Radiologists, Posteromedial Olecranon Impingement of the Pitching Elbow: Additional Findings Provided by CT. osteophytes and loose bodies, culminating in valgus extension overload syndrome (VEO).2,3 Overhead athletes with VEO have a painful throwing motion and decreased throwing velocity. The approach used in this case study provides an innovative approach to conservative UCL partial tear treatment. Valgus extension overload is well described in the throwing athlete. CT is superior in identifying some imaging features of PMOI. Impairments at evaluation included proximal stabilizing strength deficits, myofascial trigger points throughout the dominant upper extremity, improper pitching form, and inability to pitch in game conditions due to severe pain. PurposeMinor instability has been proposed as a possible aetiology of lateral elbow pain. Published by Elsevier Inc. All rights reserved. VEO results from repetitive extreme valgus forces across the elbow and comprises a constellation of injuries located at the posteromedial compartment (osteophyte formation, olecranon stress fractures, and impingement), the ulnar collateral ligament (UCL), and the radiocapitellar joint (lateral compartment chondrosis). Noticewala MS, Vance DD, Trofa DP, Ahmad CS. Emphasis on public education on the risks of overuse throwing injuries and the importance of adhering to preventative guidelines is essential in youth baseball today. Athletes at risk for valgus extension overload are also at risk for tears of the anterior bundle of the ulnar collateral ligament.
