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...

Medial-sided elbow pain is becoming more common among pediatric overhead sport athletes. One potential cause of this is a partial or complete tear of the ulnar collateral ligament (UCL). Because the growth plate remains open in many of these athletes, the most common injury experienced is an avulsion at the medial epicondyle. However, although rare, there is a potential to tear the UCL, with the most common tears occurring at the anterior bundle. However, tears to the posterior bundle are quite rare in pediatric patients...

Introduction: Old neglected posterior type of elbow dislocations is not very common and generally requires open reduction. It was usually treated with open reduction and K-wire stabilization. We did a newer method in which in addition cruciate type ligament reconstruction; we have reconstructed lateral ulnar collateral ligament (LUCL) and UCL (medial collateral ligament) using semitendinosus graft. This allowed extra stability and early mobilization of the elbow joint. Authors report 3-month-old neglected posterior type of elbow dislocation without any fracture...

Background: Jobe revolutionized the treatment of medial ulnar collateral ligament (MUCL) tears with his reconstruction technique. However, not all MUCL injuries require operative management; Rettig showed that 42% of MUCL injuries respond to conservative management. This was improved by Podesta, who showed that augmentation of nonoperative management with platelet-rich plasma (PRP) and magnetic resonance imaging (MRI) for detecting partial MUCL tears resulted in significantly higher success rates...

We present seven cases of a relatively rare swan neck deformity resulting from chronic radial collateral ligament (RCL) injury of the proximal interphalangeal (PIP) joint in the little finger. All patients were middle-aged women (mean 51 years old, range 42-55), and the duration between the initial injury and surgery was 20 years (range 5-40). The chief complaint was painful snapping of the PIP joint. All patients had hyperextension and ulnar deviation of the PIP joint with mobile swan neck deformities that had not improved with conservative treatment...

PURPOSE: There has been increased interest in the role of the posterior bundle of the medial collateral ligament (pMUCL) in the elbow, particularly its effects on posteromedial rotatory stability. The ligament's effect in the context of an unfixable coronoid fracture has not been the focus of any study. The purposes of this biomechanical study were to evaluate the stabilizing effect of the pMUCL with a transverse coronoid fracture and to assess the effect of graft reconstruction of the ligament...

One cannot overstate the importance of a thorough history and physical examination, supplemented with directed imaging, to help pinpoint the exact cause of the athlete's elbow pain. Although plain radiographs should not be overlooked, advanced imaging plays a critical role in diagnosis and management of pathology in the thrower's elbow, including computed tomography, magnetic resonance imaging, and stress ultrasound. By judiciously combining these elements, the clinician can appropriately manage these injuries in order to successfully return the athlete to their preinjury level of play...
