Transosseous Suture Fixation of Avulsion Fracture of the Ulnar Collateral Ligament of the Thumb Metacarpophalangeal Joint.

Cureus 2020 Apr 30;12(4):e7902. Epub 2020 Apr 30.

First Orthopaedic Department, Children's General Hospital Panagiotis & Aglaia Kyriakou, Athens, GRC.

Acute traumatic avulsion or rupture of the ulnar collateral ligament (UCL) of the thumb metacarpophalangeal (TMP) joint is a frequent sports-related injury. If not diagnosed and treated early, it may lead to chronic instability, pain, and loss of pinch and grip strength and possibly osteoarthritis. UCL insufficiency may be treated by various techniques, such as bone anchors, transosseous sutures with or without a pull-out button, tendon grafts, or with TMP joint fusion in neglected cases with arthrosis.

Primary Repair of Proximal Ulnar Collateral Ligament Ruptures in Pediatric Overhead Athletes.

Arthrosc Tech 2020 May 4;9(5):e639-e643. Epub 2020 May 4.

Department of Orthopaedic Surgery, Henry Ford Hospital, Detroit, Michigan, U.S.A.

Ulnar collateral ligament (UCL) injury is commonly seen in overhead throwing athletes resulting from the repetitive valgus stress placed on the medial elbow. UCL injuries (attenuation, insufficiency, or rupture) can result in medial elbow pain, a loss of pitch velocity and accuracy, and increased fatigue. Diagnosis can be made by performing a thorough physical examination along with imaging if indicated, such as ultrasound or magnetic resonance imaging. Read More

Ulnar Collateral Ligament Evaluation and Diagnostics.

Clin Sports Med 2020 Jul;39(3):503-522

Division of Sports Medicine, The Rothman Institute at Thomas Jefferson University, 925 Chestnut Street, 5th Floor, Philadelphia, PA 19107, USA. Electronic address:

The overhead throwing motion subjects the elbow to a predictable pattern of forces, including medial tension, lateral compression, and posterior shear, that in turn result in a predictable pattern of injuries. Careful history taking, thorough physical examination, and judicious diagnostic imaging allow clinicians to correctly diagnose ulnar collateral ligament (UCL) injury. Athletes with UCL injury complain of acute or chronic medial elbow injury, resulting in decreased throwing effectiveness, with loss of control and/or velocity. Read More

UCL Injury in the Non-throwing Athlete.

Curr Rev Musculoskelet Med 2019 Dec;12(4):527-533

Kerlan Jobe Institute, 6801 Park Terrace, Los Angeles, CA, 90045, USA.

Purpose Of Review: Primarily reported in the overhead throwing athlete, ulnar collateral ligament (UCL) injuries have been extensively studied since Dr. Frank Jobe first described his technique for ulnar collateral ligament reconstruction on professional baseball pitcher Tommy John. While the framework for our understanding of UCL injury was initially established studying the repetitive valgus loading of the throwers' elbow, other sport-related activities in non-throwing athletes can impart similar valgus stress on the medial elbow placing the UCL at risk for injury.

BASEBALL PLAYERS DIAGNOSED WITH ULNAR COLLATERAL LIGAMENT TEARS DEMONSTRATE GREATER SIDE TO SIDE DIFFERENCES IN PASSIVE GLENOHUMERAL ABDUCTION RANGE OF MOTION COMPARED TO HEALTHY CONTROLS.

Int J Sports Phys Ther 2019 Jun;14(3):353-358

Texas Health Sports Medicine, Fort Worth, TX, USA.

Background: Numerous studies have shown that baseball players develop range of motion adaptations in their throwing arm. While some of these shoulder range of motion adaptations can lead to greater throwing velocity, excessive changes in shoulder range of motion can increase the risk of injury to the ulnar collateral ligament (UCL).

Purpose/hypotheses: The purpose of this study was to compare the passive GH-ABD ROM measures of baseball players with a diagnosed UCL tear (UCL group) to a group of age, activity, and position matched healthy controls (CONT group). Read More

Arthroscopically-assisted fixation of anteromedial coronoid facet fracture and lateral ulnar collateral ligament repair for acute posteromedial rotatory fracture dislocation of the elbow.

Shoulder Elbow 2019 Oct 8;11(5):378-383. Epub 2017 Nov 8.

Wrightington Upper Limb Unit, Wrightington Hospital, Wigan, UK.

If left untreated, varus posteromedial rotatory injuries of the elbow result in poor functional outcomes. Surgical treatment allows restoration of elbow kinematics, minimizing the chances of chronic varus instability and early onset osteoarthritis. However, large exposures are associated with extensive soft tissue stripping, a high risk of infection, nerve injury, poor visualization of the articular surface and longer recovery. Read More
