BACKGROUND: In recent years, there has been a dramatic rise in the annual number of ulnar collateral ligament (UCL) reconstructions performed in amateur baseball pitchers. Accordingly, increasing numbers of players are entering professional baseball having already undergone the procedure; however, the effect of prior UCL reconstruction on future success remains unknown. PURPOSE: (1) To provide an epidemiologic report on baseball players who undergo UCL reconstruction before being selected in the Major League Baseball (MLB) Draft, (2) to define the outcomes in terms of statistical performance, and (3) to compare these results with those of matched controls (ie, non-UCL reconstruction)...

Medial epicondyle fractures of the humerus account for 11%-20% of all elbow injuries in children. Although intra-articular incarceration of the medial epicondyle occurs in 5%-18% of medial epicondyle fractures associated with an elbow dislocation, the mechanism of intrusion of the fracture fragment is unknown. We report a case of an irreducible elbow fracture and dislocation due to incarceration of the medial epicondyle fragment of the humerus, classified as a Watson-Jones type 3 fracture of the medial epicondyle, and present the mechanism of the intra-articular incarceration of the medial epicondyle fragment...

Shoulder and elbow injuries have been described in baseball players as early as the 1940s. Ulnar collateral ligament (UCL) tears have been recognized as a significant source of disability for baseball players and have been seen in increasing frequency as training regimens and level of play have become more intense and rigorous. Our understanding and treatment of these injuries have also evolved over time. This article summarizes the evolution of the treatment of UCL tears and discusses future directions for the treatment and prevention of these injuries...

Objective: Fractures of the capitellum are rare injuries but are often more complex and of a greater extent than assumed from conventional radiographs. Classification is usually based on their extension in relation to the trochlea the trochlea and on the number of fragments. Information on associated injuries is limited and only reported in small case series. The aim of this retrospective study was to report on our experience with capitellar fractures and their associated injuries. Methods: We retrospectively reviewed all patients treated for fractures of the capitellum humeri at our institute between 2005 and 2017...

The treatment of sports injuries in the skeletally immature has a unique set of complications. Growth deformity may occur after anterior cruciate ligament reconstruction; therefore, skeletal age is used to help guide the choice between physeal sparing and transphyseal techniques. Arthrofibrosis after tibial spine fracture fixation can be reduced by initiating immediate range of motion, and should be treated early and cautiously to avoid iatrogenic fracture. Nonunions of medial epicondyle elbow fractures are more common with nonoperative treatment, but seldom lead to clinical problems outside of certain athletes...

OBJECTIVE: Multimodality elbow screening of adolescent baseball players shows apparent laterality in morphology and signal intensity of the medial epicondyle on dedicated magnetic resonance imaging. We aimed to elucidate actual imaging laterality in the medial epicondyle by comparing magnetic resonance images of the dominant and contradominant elbows and to clarify the clinical meaning and mechanism of this phenomenon. MATERIALS AND METHODS: We used a 0.2-T dedicated magnetic resonance imaging scanner...

BACKGROUND: Previous research indicates that the amount of valgus torque placed on the elbow joint during overhead throwing is higher than the medial ulnar collateral ligament (UCL) can tolerate. Wrist and finger flexor muscle activity is hypothesized to make up for this difference, and in vitro studies that simulated activity of upper extremity musculature, specifically the flexor digitorum superficialis and flexor carpi ulnaris, support this hypothesis. PURPOSE: To assess the medial elbow joint space at rest, under valgus stress, and under valgus stress with finger and forearm flexor contraction by use of ultrasonography in vivo...

Background: Ulnar collateral ligament (UCL) injuries have increased significantly in recent years, and reconstruction has become the preferred treatment for UCL injury over ligament repair. In a recent study, UCL repair with internal bracing demonstrated significantly greater resistance to gap formation in biomechanical tests, even at low cycles of valgus loading. Purpose/Hypothesis: The purpose of this study was to compare the fatigue and failure mechanics of traditional UCL reconstruction with UCL repair and internal bracing...

BACKGROUND: The human elbow maintains its stability mainly through its bony structure. Stability is enhanced by ligamentous structures. To allow the ligamento-muscular reflex, which protects against strain and stress, mechanoreceptors are embedded in the ligament. This report describes the existence and the distribution of the elbow medial collateral ligaments (MCLs) mechanoreceptors. HYPOTHESIS: 1) the bony attachment site has the highest density of mechanoreceptors, and 2) the anterior part has the highest density of mechanoreceptors...

Postoperative C5 paralysis is a serious complication of cervical spine surgery, with no established method for effective rehabilitation. A 67-year-old man presented with postoperative bilateral C5 paralysis following cervicothoracic surgery for ossification of the posterior longitudinal ligament (OPLL). Starting 15 days after surgery, left elbow joint training was performed 2-3 times weekly, for a total of 10 sessions, using an upper limb single-joint hybrid assistive limb (upper limb HAL-SJ). Right elbow joint training was also performed 5 times weekly starting 38 days after surgery, for a total of 10 sessions, using the upper limb HAL-SJ...

INTRODUCTION: Dislocation of the elbow associated with radial head and coronoid fracture, the so-called "terrible triad" of the elbow, is challenging to treat and has a history of complicated outcomes. This study is to compare the clinical outcome of a single lateral approach-the extensile splitting extensor digitorum communis (EDC) approach and combined lateral and medial (CML) approaches for the treatment of terrible traid of the elbow (TTE). MATERIAL AND METHODS: After appropriate exclusion, 60 TTE patients (28 patients in the EDC group, 32 patients in the CML group) from 2009 January to 2015 August were reviewed in this study...

BACKGROUND: The aim of this study was to compare the complete visible surface area of the radial head, neck, and coronoid in the Kaplan and Kocher approaches to the lateral elbow. The hypothesis was that the Kaplan approach would afford greater visibility due to the differential anatomy of the intermuscular planes. METHODS: Ten cadavers were dissected with the Kaplan and Kocher approaches, and the visible surface area was measured in situ using a 3-dimensional digitizer...

The "Docking Plus" technique for elbow ulnar collateral ligament (UCL) surgery is described in the following text and video. Depite the general success of UCL surgery, significant rates of retear and failure of return to competition persist. Hypothesized reasons for UCL surgery failure include insufficient graft strength (midsubstance tears), insufficient graft tensioning (functional UCL insufficiency, valgus extension overload), and insufficient healing of graft to bone (proximal avulsions). This technique is meant to incorporate the best aspects of the previously described techniques for UCL reconstruction to create a larger, stronger, better-tensioned graft with a larger healing surface area to bone, a lower retear rate, and a lower risk of complications...

Reconstruction of the lateral ulnar collateral ligament of the elbow is the primary treatment for recurrent symptomatic posterolateral rotatory instability. Although a number of lateral ulnar collateral ligament reconstruction techniques have been described, the docking technique has received general acceptance. In this technique, the graft is passed through a tunnel on the ulnar side and the 2 free limbs are docked into the humerus at the isometric point on the lateral condyle. Advantages of this method of reconstruction include reduced bone removal, decreased soft tissue damage, and precise control of graft tensioning...

BACKGROUND: There has been no study on radiologic changes after medial ulnar collateral ligament (MUCL) reconstruction and related clinical features. METHODS: Data from 39 baseball players who underwent MUCL reconstruction were collected and analyzed. The baseball players were classified into 2 groups according to the starting point of the humeral tunnel: (1) the lower tip of the medial epicondyle (group NA, n = 21) and (2) the remnant of the MUCL (group A, n = 18)...

PURPOSE OF REVIEW: This review aims to describe the nonreconstructive options for treating ulnar collateral ligament (UCL) injuries ranging from nonoperative measures, including physical therapy and biologic injections, to ligament repair with and without augmentation. RECENT FINDINGS: Nonoperative options for UCL injuries include guided physical therapy and biologic augmentation with platelet-rich plasma (PRP). In some patients, repair of the UCL has shown promising return to sport rates by using modern suture and suture anchor techniques...
