Incidental Os Odontoideum in an Adolescent Athlete With Sports-Related Concussion
Abstract: Sports-related concussion (SRC) is a frequent injury in the adolescent population with presentation including a wide array of signs and symptoms. There are no universally agreed upon guidelines for when to pursue advanced imaging, such as magnetic resonance imaging (MRI), in the workup of SRCs in the adolescent population. Our experience indicates that MRI rarely contributes to management. This case report highlights a rare finding of os odontoideum on MRI imaging in an adolescent female soccer player in the setting of treatment of an SRC that altered the course of her clinical management.

Endoscopic Ischial Tuberosity Osteophyte Resection for Treatment of Ischiofemoral Impingement: A Case Report
We report an endoscopic procedure involving ischial tuberosity osteophyte resection with refixation of the partially detached hamstring insertion through a posterior approach in the prone position. Using this technique, it is easier to reach the lesion and less likely to injure the sciatic nerve. The postoperative pain score (visual analogy score) was significantly decreased, the modified Harris hip score increased from 39 preoperatively to 86 postoperatively, and there was no adverse effect on the hamstring tendon.

Subsartorius Fascial Plane Hydrodissection as Novel Treatment for Hunter's Canal Syndrome
Abstract: Saphenous entrapment neuropathy in the distal thigh most commonly occurs at Hunter's canal and is characterized by neurologic symptoms distal to the midthigh in the saphenous nerve distribution. Presented is a 23-year-old active duty female service member with left medial knee pain worse with knee flexion and extension. Evaluation raised suspicion for saphenous nerve entrapment at Hunter's canal, and ultrasound-guided subsartorius fascial plane hydrodissection was performed in addition to focused rehabilitation of the adductor and core musculature. No reports of this treatment have been published to date. Thi...

Healing Predictors of Conservative Treatment for Juvenile Osteochondritis Dissecans of the Talus
Objective: To investigate the healing response of juvenile osteochondritis dissecans (JOCD) of the talus after conservative treatment, identify healing predictors, and develop a predictive model for healing. Design: Retrospective study. Setting: Clinics at a tertiary-level pediatric medical center. Patients: Fifty-five patients (55 ankles) who presented with JOCD. Interventions: Patients were managed with cast immobilization followed by activity restriction. Main Outcome Measures: The primary outcome measure of progressive lesion reossification was determined from the latest radiograp...

Observed Injury Rates Did Not Follow Theoretically Predicted Injury Risk Patterns in Professional Human Circus Artists
Conclusions: Although theoretical classifications are the only option when no data are available, observed risk patterns based on injury surveillance programs can help identify artists who have a high (or low) theoretical risk but are nonetheless actually at low (or high) risk of injury, given their current roles. This will help develop more cost-effective selective injury prevention programs. (Source: Clinical Journal of Sport Medicine)

Number of Months of Baseball in the Previous Year and Preseason Olecranon Tenderness: Risk Factors for Shoulder and Elbow Injuries in High-School Baseball Players
Conclusions: Baseball players who developed arm injuries during a season were more likely to play more months of baseball and report shoulder pain in the previous year. The presence of preseason olecranon tenderness was associated with nearly triple the risk of injury during the season. Every additional month of baseball participation in the previous year was associated with a 1.2× increased odds of injury. The presence of glenohumeral internal rotation deficit was not a predictor of injury. (Source: Clinical Journal of Sport Medicine)

Evaluating the Effect of Policy Prohibiting Body Checking on Physical Contacts in U15 and U18 Youth Ice Hockey Leagues
Conclusions: The incidence of BC was 82% lower in the U15 and 84% lower in U18 levels not allowing BC, with lower HC and other PC rates also in non-BC leagues. These findings demonstrate high adherence with BC policy change in youth ice hockey. (Source: Clinical Journal of Sport Medicine)

Return to Full Participation Following Concussion in the National Football League, 2015 Through 2020
Conclusions: The 9-day median time missed post-concussion may be related to emphasis on graduated phase-based concussion management. No concussed player returned to competition on the day of injury, and less than 40% participated in games the following week. Further work is needed to better understand characteristics of concussions that take longer to return and movement through stages of return. (Source: Clinical Journal of Sport Medicine)

Does Increasing the Severity of Penalties Assessed in Association With the “Zero Tolerance for Head Contact” Policy Translate to a Reduction in Head Impact Rates in Youth Ice Hockey?
Conclusions: The HC-policy amendments have led to decreased HC1 rates. However, referee enforcement can further boost the HC-policy effectiveness. These findings can help future referee training and potential rule modifications to increase player safety nationally. (Source: Clinical Journal of Sport Medicine)

Relationship and Latent Factors Between Clinical Concussion Assessments and the Functional Standardized Assessment of Reaction Time (StART)
Conclusions: StART displayed 3 distinct categories and had minimal redundancy within its subtests. StART did not meaningfully correlate with clinical assessments, suggesting that StART provides unique information by examining more functional, reactive movement.

No Association Between Processing Speed and Risk of Sport-Related Concussion in Youth Soccer
Objective: To determine whether slow processing speed is associated with risk of sport-related concussion. Design: We conducted a retrospective cohort study using computerized neurocognitive assessments (Immediate Post-concussion Assessment and Cognitive Testing [ImPACT]) from the Massachusetts Concussion Management Coalition. Slow processing speed was defined as 2 SD below the sample mean (n = 131) and fast processing speed as 2 SD above the sample mean (n = 259). We used a binary logistic regression model to determine the odds of sustaining a concussion with our main predictor being processing speed (high or l...

Characterizing Symptoms Before and Following Concussion in Professional Hockey
Objective: Examine SCAT5 baseline and acute symptom subscales in professional hockey players. Design: Longitudinal case–control. Setting: Preseason medical evaluations and suspected concussion evaluations. Participants: NHL/AHL players were given the NHL-modified SCAT5 before the 2018-2019 season (n = 1924). During the season, English-speaking players evaluated within 1 day of injury and diagnosed with concussion (n = 140) were compared with players evaluated for possible concussion, but not given a concussion diagnosis (n = 174). Independent Variables: Concussion diagnosis and demographic...
