Glenohumeral rotation deficits in high school, college, and professional baseball pitchers with and without a medial ulnar collateral ligament injury.

J Shoulder Elbow Surg 2019 Mar;28(3):423-429

Andrews Institute for Orthopaedics and Sports Medicine, Gulf Breeze, FL, USA; Andrews Research and Education Foundation, Gulf Breeze, FL, USA.

Background: It is unclear how a glenohumeral internal rotation (IR) loss (GIRLoss), a glenohumeral external rotation (ER) gain (GERGain), or a total rotational motion (TRM) deficit (TRMD) predict medial ulnar collateral ligament (MUCL) injury risk among high school (HS), college (COLL), and professional (PRO) baseball pitchers with and without MUCL injury. We hypothesized that pitchers with MUCL injury would have more GIRLoss and TRMD compared with pitchers without MUCL injury, with no differences in IR, ER, TRM, GIRLoss, GERGain, and TRMD.

Methods: The study equally divided 216 male HS, COLL, and PRO pitchers into the MUCL injury group (n = 108) and a control group (n = 108) without MUCL injury. Read More

Medial elbow stability assessment after ultrasound-guided ulnar collateral ligament transection in a cadaveric model: ultrasound versus stress radiography.

J Shoulder Elbow Surg 2019 Feb 13. Epub 2019 Feb 13.

Andrews Research and Education Foundation, Gulf Breeze, FL, USA.

Background: The ulnar collateral ligament (UCL), consisting of 3 bundles, is the primary medial restraint in the elbow. Recent research has demonstrated that ultrasound is an effective modality to evaluate the medial elbow, whereas stress radiography is standard practice in the measurement of medial elbow laxity. This study (1) compared dynamic ultrasound (US) with stress radiography in the evaluation of UCL insufficiency and (2) further evaluated the contribution of the anterior bundle of the UCL to medial elbow stability.

Biomechanical Comparison of Ulnar Collateral Ligament Reconstruction With a Modified Docking Technique With and Without Suture Augmentation.

Am J Sports Med 2019 Jan 28:363546518820304. Epub 2019 Jan 28.

West Coast Sports Institute, San Francisco, California, USA.

Background:: Throwing athletes with ulnar collateral ligament (UCL) injury and symptomatic valgus instability can expect to return to the same or higher level of play. Reconstruction with tendon graft is the dominant method of surgical treatment. Recent evidence suggests that spanning the joint with a suture anchored on both sides is biomechanically equivalent to reconstruction, with faster time to return to play. Read More

Hamstring Injuries in Major League Baseball Pitchers: Implications in Graft Selection for Ulnar Collateral Ligament Reconstruction.

Am J Sports Med 2019 Feb 13;47(2):444-450. Epub 2018 Dec 13.

Kerlan-Jobe Orthopaedic Clinic, Los Angeles, California, USA.

Background:: Hamstring tendons are commonly harvested as autograft for ulnar collateral ligament reconstruction. There is no consensus in the literature whether the hamstring tendon should be harvested from the ipsilateral (drive) leg or contralateral (landing) leg of baseball pitchers undergoing ulnar collateral ligament reconstruction. Hamstring injuries commonly occur in baseball players, but there are no reports on their incidence specifically among Major League Baseball (MLB) pitchers, nor are there reports on whether they occur more commonly in the drive leg or the landing leg.

Adolescent Pitcher Recovery from Partial Ulnar Collateral Ligament Tear after Platelet-Rich Plasma.

Curr Sports Med Rep 2018 Dec;17(12):407-409

Georgetown University School of Medicine, MedStar National Rehabilitation Network, Washington, DC.

Platelet-rich plasma (PRP), as a regenerative treatment for partial ulnar collateral ligament (UCL) tears, is validated to lead to faster clinical recovery and return to play in adult athletes. However, studies examining such a role of PRP in younger pediatric and adolescent athletes are scarce. A 14-year-old adolescent throwing athlete, a right-handed pitcher, presented with chronic right medial elbow pain discovered to be secondary to a partial UCL tear, as identified on both ultrasound and magnetic resonance imaging.

Chronic Medial Epicondyle Avulsion: Technique of Fragment Excision and Ligament Reconstruction With Internal Brace Augmentation.

J Am Acad Orthop Surg 2019 Jan;27(2):e64-e69

From the Kaiser Permanente Southern California (Dr. Mirzayan), Baldwin Park, CA, and the University of Southern California Keck School of Medicine (Dr. Cooper), Los Angeles, CA.

Medial epicondyle fracture nonunions of the elbow may lead to symptomatic instability in the high-demand or overhead athlete. These injuries are challenging to treat surgically because of the small residual bony fragment, the scarred and shortened chronically injured ulnar collateral ligament (UCL), which prevents it from being mobilized and reduced to its native position. To date, most described methods aim at reducing the displaced fragment and achieving union with the humerus. Read More

Open Treatment of Radial Head Fractures.

JBJS Essent Surg Tech 2017 Dec 13;7(4):e35. Epub 2017 Dec 13.

Mayo Clinic, Rochester, Minnesota.

Radial head fractures may commonly be treated by (1) open reduction and internal fixation (ORIF), (2) radial head excision, or (3) radial head replacement. If there is no associated elbow instability with lateral ulnar collateral ligament (LUCL) injury, the preferred approach is via a split in the extensor digitorum communis (EDC) origin. This provides a wide exposure but limits the risk of injury to the LUCL and associated instability. Read More

Monteggia fracture with unreducable anterior dislocation of the radial head and a lesion of the external collateral ligament of the elbow.

Pan Afr Med J 2018 18;29:216. Epub 2018 Apr 18.

Department of Orthopaedic Surgery, University Hospital, Monastir 5000, Tunisia.

Monteggia described a fracture of the proximal third of the ulna with anterior dislocation of the radial head from both the proximal radioulnar and radiocapitellar joints. The key treatment principle in Monteggia fractures is stable anatomic alignment of the ulna. We present an uncommon case of a Monteggia fracture-dislocation with an unreducable anterior dislocation of the radial head and associated with a lesion of the lateral collateral ligament of the elbow.

The role of the posterior bundle of the medial collateral ligament in posteromedial rotatory instability of the elbow.

Bone Joint J 2018 08;100-B(8):1060-1065

Department of Orthopedics, Biomechanics Laboratory, Mayo Clinic, Rochester, Minnesota, USA.

Aims: The aim of this study was to evaluate two hypotheses. First, that disruption of posterior bundle of the medial collateral ligament (PMCL) has to occur for the elbow to subluxate in cases of posteromedial rotatory instability (PMRI) and second, that ulnohumeral contact pressures increase after disruption of the PMCL.

Materials And Methods: Six human cadaveric elbows were prepared on a custom-designed apparatus which allowed muscle loading and passive elbow motion under gravitational varus. Read More
