Cervical Spine CT Can Miss Fractures in American Football Players When Protective Equipment is in Place: A Cadaver Study

The standard knee pad is considered the most ineffective personal protective equipment in the American football player’s uniform. This study quantitatively and qualitatively assesses personal protective equipment for the lower body for U.S. football players against the VAPPR Pad (Vastus And Patellar Protection with Range of motion), the next iteration of lower body protection. The study consisted of player surveys, material drop testing, and Performance Drill testing including broad-jump, L-drill, pro-agility, and gait analysis with 138 participants in the initial survey and 25 men in the physical testing. Results of the Performance Drill Testing proved that unpadded players perform at higher levels than padded players; established no difference in performance between the unpadded players and players wearing the VAPPR Pad; and validated the VAPPR Pad’s superiority to the standard knee pad.

Cervical Facet

Acute cervical facet fractures are increasingly being detected due to the use of cervical spine CT imaging in the initial assessment of trauma patients. For displaced cervical facet fractures with dislocations and subluxations, early surgery can decompress the spinal cord and stabilize the spine. For patients with non-displaced cervical facet fractures, the challenge in managing these patients is the determination of spinal stability. Although many of the patients with non-displaced cervical facet fractures can be managed with a cervical collar, the imaging needs to be analyzed carefully since certain fracture patterns may be better managed with early surgical stabilization.

BACKGROUND: Few studies have investigated the variations in body composition and performance in Japanese collegiate American-football players. OBJECTIVE: To clarify what characterizes competitors at the highest levels – in the top division or on the starting lineup – we compared players’ body compositions and performance test results. METHODS: This study included 172 players. Each player’s body composition and performance (one-repetition maximum bench press, one-repetition maximum back squat, and vertical jump height) were measured; power was estimated from vertical jump height and body weight. Players were compared according to status (starter vs. non-starter), position (skill vs. linemen), and division (1 vs. 2). Regression analysis was performed to determine characteristics for being a starter. RESULTS: Players in higher divisions and who were starters were stronger and had more power, greater body size, and better performance test results. Players in skill positions were relatively stronger than those in linemen positions. Vertical jump height was a significant predictor of being a starter in Division 1. CONCLUSION: Power and vertical jump may be a deciding factor for playing as a starter or in a higher division.

Contact Pressures

Background: The relationship between turf toe and plantar foot pressures has not been extensively studied. Two hypotheses were tested in a cohort of professional American football players: first, that a history of turf toe is associated with increased peak hallucal and first metatarsophalangeal (MTP) plantar pressures; second, that decreased range of motion (ROM) of the first MTP correlates with increased peak hallucal and first MTP plantar pressures. Materials and Methods: Forty-four athletes from one National Football League (NFL) team were screened for a history of turf toe during preseason training. Dorsal passive MTP ROM and dynamic plantar pressures were measured in both feet of each player. Anatomical masking was used to assess peak pressure at the first MTP and hallux. Results: First MTP dorsiflexion was significantly lower in halluces with a history of turf toe (40.6 ± 15.1 degrees versus 48.4 ± 12.8 degrees, p = 0.04). Peak hallucal pressures were higher in athletes with turf toe (535 ± 288 kPa versus 414 ± 202 kPa, p = 0.05) even after normalizing for athlete body mass index ( p = 0.0003). Peak MTP pressure was not significantly different between the two groups tested. First MTP dorsiflexion did not correlate with peak hallucal or first MTP pressures. Conclusion: This study showed that turf toe is associated with decreased MTP motion. In addition, increased peak hallucal pressures were found. Further study is warranted to determine whether these pressures correlate with the severity of symptoms or progression of turf toe to first MTP arthritis.

Rule Out

ABSTRACT Objective: Emergency physicians are expected to rule out clinically important cervical spine injuries using clinical skills and imaging. Our objective was to determine whether emergency physicians could accurately rule out clinically important cervical spine injuries using computed tomographic (CT) imaging of the cervical spine. Method: Fifteen emergency physicians were enrolled to interpret a sample of 50 cervical spine CT scans in a nonclinical setting. The sample contained a 30% incidence of cervical spine injury. After a 2-hour review session, the participants interpreted the CT scans and categorized them into either a suspected cervical spine injury or no cervical spine injury. Participants were asked to specify the location and type of injury. The gold standard interpretation was the combined opinion of two staff radiologists. Results: Emergency physicians correctly identified 182 of the 210 abnormal cases with cervical spine injury. The sensitivity of emergency physicians was 87% (95% confidence interval [CI] 82–91), and the specificity was 76% (95% CI 74–77). The negative likelihood ratio was 0.18 (95% CI 0.12–0.25). Conclusion: Experienced emergency physicians successfully identified a large proportion of cervical spine injuries on CT; however, they were not sufficiently sensitive to accurately exclude clinically important injuries. Emergency physicians should rely on a radiologist review of cervical spine CT scans prior to discontinuing cervical spine precautions.
