Article Synopsis
- Research indicates a higher prevalence of upper lumbar spondylolysis in young athletes than previously thought, highlighting a lack of sport-specific studies on this condition.
- The study aimed to identify risk factors associated with upper lumbar stress injuries in pediatric and adolescent athletes by reviewing medical records from two academic centers.
- Results showed that the majority of diagnosed athletes had lower level injuries, while a smaller percentage experienced upper level injuries, which were linked to being older at diagnosis and shorter durations of low back pain.
Article Synopsis
- Previous studies indicated that spondylolysis mainly affects the L5 and L4 levels, with minimal occurrences at higher levels, but recent findings show that MRI is as effective as CT for early detection without radiation risks.
- The hypothesis suggests that using MRI more frequently might uncover more cases of spondylolysis at upper spinal levels, which were underreported.
- A study investigated medical records of 902 young athletes, revealing that most stress injuries were lower lumbar, but 9.1% were found at or above the L3 level, highlighting the significance of sport participation and symptom duration.
Background: Showcase participation has been considered a risk factor for elbow injuries. It remains unclear whether high school (HS) showcase volume negatively affects pitchers' career paths. Because pitchers are achieving 90 mph thresholds at younger ages, it is unknown whether shorter time intervals between achieving 90 mph thresholds and dates of ulnar collateral ligament reconstruction (UCL-R), known as time to tear (TTT), may affect career trajectory.

Although showcase participation has been considered an injury risk factor, limited data are available to corroborate this association.
Hypothesis: Elite pitchers achieving fastball velocities ≥90, ≥92, and ≥95 mph at younger ages would be more likely to undergo UCLR earlier in their careers compared with pitchers not achieving these velocity thresholds at younger ages.
