Background: No model exists to predict which patients with elbow ulnar collateral ligament (UCL) injuries will successfully return to play (RTP) after nonoperative treatment. The reported rates for successful RTP after the nonoperative management of UCL injuries are limited and vary widely. Furthermore, patient and injury characteristics that influence the failure of nonoperative treatment have not been established.

Since popularized by Native Hawaiian Olympian, Duke Kahanamoku, in the early 20th century, surfing has grown into a globally popular sport. Because the prevalence of surfing continues to grow, physicians should be familiar with traumatic and atraumatic surfing injuries to guide treatment and prevention. The unique biomechanics of paddling prone on the surfboard and maneuvering the surfboard with the lower extremities make the injury profile for surfers different than that of other aquatic or overhead sports.

Background: The utilization of new pitch-tracking metrics has driven player development and provides more predictive pitch-specific data on physical characteristics and performance. Given the differences in each pitcher's arsenal, these pitch-specific metrics provide new potential variables to investigate ulnar collateral ligament (UCL) injury risk.

Purpose: To evaluate the association of several pitch-specific advanced analytic and pitch-tracking metrics on UCL surgery rates in Major League Baseball (MLB) pitchers.

Purpose: To analyze the etiology, diagnosis, and incidence of head and neck (HN) injuries among ocean surfers.

Methods: The National Electronic Injury Surveillance System database was queried for surfing HN injuries presenting to United States emergency departments (EDs) between January 2003 and December 2022. Date of presentation, age, sex, race, injured body part, injury diagnosis, and disposition, as well as a brief injury narrative, were included in the data.

Rotator cuff and biceps tendon injuries are a common source of pain and dysfunction among overhead athletes. The stress across the glenohumeral joint and its dynamic stabilizers in high level throwing leads to adaptive anatomic changes that must be recognized and respected. Nonoperative treatment is recommended for partial rotator cuff tears and biceps tendinitis and tendinosis.

Article Synopsis
  • The study assesses the return to performance of MLB pitchers after undergoing ulnar collateral ligament (UCL) surgery using advanced analytics and pitch-tracking metrics.
  • At 1, 2, and 3 years post-surgery, the data showed that only 1.6% of pitchers returned to play within the first year, but the rates increased significantly to 71.9% at 2 years and 82.0% at 3 years.
  • The research highlights the importance of modern metrics, examining factors like expected fielding independent pitching and velocity, to evaluate pitchers' recovery and performance levels after surgery.

Background: This study aimed to analyze the effects of platelet-rich plasma (PRP) for partial ulnar collateral ligament (UCL) tears in athletes and predicted positive outcomes.

Methods: The researchers systematically reviewed the PubMed, Cochrane CENTRAL, MEDLINE, Scopus, and Google Scholar databases to identify studies with clinical outcomes of PRP for partial UCL tears. They excluded studies that did not stratify data by tear type or included surgical management.

  • The study examines the prevalence of shoulder and elbow injuries among baseball players in the Dominican Republic, particularly those attending a Major League Baseball scouting event.
  • A total of 75 participants were reviewed, revealing that 72% had abnormal elbow findings and 32% had shoulder abnormalities, with position players showing higher elbow issues while pitchers had more severe shoulder injuries.
  • Key findings included high rates of rotator cuff and labral issues in pitchers, and notable elbow abnormalities like UCL tears, especially given their young average age of 17.9 years.

Background: Prior to the Major League Baseball (MLB) draft, some pitchers undergo predraft magnetic resonance imaging (MRI). This study aimed to evaluate pre-draft elbow MRI on baseball pitchers who were entering the MLB draft to determine the presence or absence of pathology, the associations between these pathologies and ulnar collateral ligament (UCL) tears, and interobserver reliability regarding common MRI pathology.

Methods: Predraft elbow MRI performed on prospective MLB pitchers between 2011 and 2017 were deidentified and then reviewed by two separate authors.

Surfer's neurapraxia is a rare surfing injury of the saphenous nerve secondary to persistent compression of the saphenous nerve along the medial thigh by the surfboard when paddling prone and while sitting upright on the board waiting for a wave. Symptoms may be nonspecific and consist of pain in the medial thigh with or without radiation along the saphenous nerve distribution (medial leg, medial ankle, medial arch of the foot). The saphenous nerve tension test can be utilized to reproduce the symptoms of surfer's neurapraxia.

Objective: Social distancing protocols due to the COVID-19 pandemic resulted in premature ending of athletic seasons and cancellation of upcoming seasons, placing significant stress on young athletes. Inability to play or forced early retirement has significant consequences on athlete's mental health, as demonstrated by an extensive body of injury literature. We hypothesize that premature suspension and cancellation of athletic events due to the COVID-19 pandemic leads to higher incidence of depressive symptoms among high-school and collegiate athletes.
