INTRODUCTION: The ulnar collateral ligament (UCL) is an important medial stabilizer of the elbow, particularly in overhead-throwing athletes. However, there is no universally accepted method for evaluating UCL thickness with ultrasound (US). OBJECTIVE: To assess reproducibility of previously published methods, as well as a modified technique, for evaluating the UCL via US. We hypothesize that a modified technique would show greater reproducibility. MATERIAL AND METHODS: Using US, the thickness of the UCL in 50 volunteers was measured by two musculoskeletal trained radiologists using two different measurement techniques...

BACKGROUND: Isolated coronoid, isolated radial head, and combined coronoid and radial head fractures are common elbow fractures, and specific ligamentous injury of each fracture configuration has been reported. However, the osseous injury mechanism related to ligament status remains unclear. QUESTIONS/PURPOSES: The objectives of this study were: (1) to determine what ligamentous injury patterns (medial or lateral collateral) and bone contusion patterns (medial or lateral) are associated with isolated coronoid, isolated radial head, and combined coronoid and radial head fractures; (2) to correlate the osseous injury mechanism based on these findings with isolated coronoid, isolated radial head, and combined coronoid and radial head fractures; and (3) to determine whether isolated and combined coronoid fractures have different fracture lines through the coronoid (tip or anteromedial facet), speculated to be caused by different injury mechanisms...

BACKGROUND: Injury rates among professional baseball players may reach as high as 5.8 per 1000 encounters, with pitchers being most vulnerable on account of the excessive biomechanical load on the upper extremity during the throwing motion. Anatomically, the shoulder is the most common site of pitching-related injury, accounting for 30.7% of injuries, closely followed by the elbow at 26.3%. Characteristic valgus loading imparts a predictable constellation of stresses on the joint, including medial tension, lateral compression, and posterior medial shearing...

HYPOTHESIS: Pitchers who return to sport (RTS) sooner will have a higher risk of revision ulnar collateral ligament reconstruction (UCLR) than those who return later. METHODS: All professional (major and minor league) baseball pitchers who underwent UCLR between 1974 and 2016 were identified. Date of the index UCLR was recorded. The date of the first game back at any professional level after surgery and the date the pitcher returned to the same level of play (if applicable) were recorded...

The number of ulnar collateral ligament (UCL) reconstructions being performed has risen sharply in recent years, most notably in the young amateur athlete. While successful outcomes have been reported with reconstruction, the surgery and the associated rehabilitation timeline may be difficult for the nonelite athlete to incur. Return-to-play expectations, along with level of competition, should help guide surgeons in exploring management options. While reconstruction remains a mainstay, focused research exploring nonreconstructive options has expanded...

The ulnar collateral ligament (UCL) of the elbow acts as the primary restraint to valgus force experienced in the late cocking and early acceleration phases of overhead throwing. If the UCL or dynamic flexor-pronator musculature is incompetent, elbow extension and valgus torque, as seen in throwing, can result in posteromedial impingement with subsequent chondromalacia and osteophyte formation. Before the first UCL reconstruction, performed by Frank Jobe in 1974, this injury was considered career ending in overhead athletes...

INTRODUCTION: Though isolated traumatic extensor pollicislongus rupture and ulnar collateral ligament rupture of the metacarpophalangeal joint of the thumb are well known injuries, it is rare to have simultaneous bilateral thumb injuries from a single traumatic event. In this article, we report simultaneous bilateral traumatic thumb injury with extensor pollicislongus tendon rupture on one side and ulnar collateral ligament tear on the other side. To the best of our knowledge, such injury has never been reported in the English literature...
