The ulnar collateral ligament loading paradox between in-vitro and in-vivo studies on baseball pitching (narrative review).

Int Biomech 2021 Dec;8(1):19-29

Department of Biomechanical Engineering, Delft University of Technology, CD Delft, The Netherlands.

Ulnar collateral ligament (UCL) weakening or tears occur in 16% of professional baseball pitchers. To prevent players from sustaining a UCL injury, it is important to understand the relationship between the UCL properties and elbow stabilizers with the load on the UCL during pitching. In-vitro studies showed that the ultimate external valgus torque of 34 Nm would rupture the UCL, which is in apparent conflict with the reported peak valgus torques in pitching (40-120 Nm).

Stener-like lesions in the hand, knee and foot: a review of anatomy, mechanism of injury and imaging evaluation.

Clin Imaging 2021 May 6;76:235-246. Epub 2021 May 6.

Department of Musculoskeletal Radiology, Fleury Medicina e Saúde Higienópolis, Rua Mato Grosso 306, 1° Andar, Higienópolis, São Paulo, SP 01239-040, Brazil. Electronic address:

A Stener lesion is a displaced tear of the ulnar collateral ligament in the metacarpophalangeal joint of the thumb in which the adductor pollicis aponeurosis is positioned between the retracted ligament and the injury site, preventing natural healing. This lesion was first described in 1962, and since then, both radiologists and orthopedists have considered it important to treat surgically. Although this lesion was originally described in the thumb, this injury mechanism can occur in other joints of the hand, knee, and foot. Read More

Nonsurgical Management of Ulnar Collateral Ligament Injuries.

J Am Acad Orthop Surg Glob Res Rev 2021 04 9;5(4). Epub 2021 Apr 9.

From the Department of Orthopedics, New York Presbyterian, Columbia University Medical Center, New York, NY (Dr. Swindell, Dr. Trofa, Dr. Alexander, and Dr. Ahmad); the OrthoCarolina Sports Medicine Center, Charlotte, NC (Dr. Sonnenfeld and Dr. Saltzman); and the Department of Orthopaedic Surgery, Atrium Health Musculoskeletal Institute, Charlotte, NC (Dr. Saltzman).

Ulnar collateral ligament (UCL) injuries are a common source of pain and disability in the overhead athlete and often result in notable loss of time from competition. Over the past 10 to 15 years, the prevalence of UCL injury and reconstruction has undergone a dramatic increase, making it imperative to determine which patients may benefit from a nonsurgical regimen. Nonsurgical treatment involves a multidisciplinary approach of rehabilitation with tailored physical therapy programs and, in certain cases, biologic adjuncts. Read More

Negative Pressure Wound Therapy With Instillation and Dwell Time Used to Treat a Complex Open (Terrible Triad) Injury of the Elbow: A Case Report.

Wounds 2020 Dec;32(12):E126-E129

Department of Orthopedic Surgery and Trauma, Regional Hospital of Orleans, Orleans, France.

Introduction: Treating a complex elbow injury known as the terrible triad, combined with a severe soft tissue trauma, is challenging for most orthopedic surgeons and can lead to permanent disabilities and poor functional outcomes if reconstruction is inadequate.

Case Report: A 75-year-old male with a history of high blood pressure was injured in an accident involving agricultural equipment and presented with a triad injury of the left elbow: a posterolateral dislocation combined with fractures of the radial head (Mason-Johnson Type II) and ulnar coronoid process (Morrey Type 1). Fractures to the radial head and ulnar coronoid process and injuries to the lateral collateral ligament and triceps tendon were repaired, and a local skin flap was preserved to provide adequate soft tissue coverage.
