A stiff-legged gait: benign acute childhood myositis
CMAJ
ORIGINAL ARTICLE: Apreviously healthy 6-year-old boy was brought to the emergency department with a sudden inability to walk or bear weight on his legs. Four days earlier, he had experienced a fever and runny nose and was given symptomatic treatment with simple analgesics at home. For the next two days, he had sporadically complained of “sore legs” and would transiently “toe-walk,” only to subsequently take off running without any difficulty. On the morning of the fifth day of his illness, although his fever and coryza were improving, he had been unable to get out of bed. When his mother attempted to stand him up, he was unable to bear weight on his legs. He would ambulate only by crawling on all fours.
Epidemiology and Outcomes of Achilles Tendon Ruptures in the
National Football LeagueUPOJ
ORIGINAL ARTICLE: The purpose of this study is to document the epidemiology of Achilles tendon ruptures in the NFL and to quantify the impact of these injuries upon player performance. Data on NFL Achilles tendon ruptures occurring between 1997 and 2002 was gathered. Power ratings for each player were calculated for the three seasons before and after the Achilles tendon injury. Statistical analysis was performed. Thirty-one Achilles tendon ruptures in NFL players between 1997 and 2002 were identified. Players generally took 9 to 12 months to return to play, and 32.3% of players never returned to play (p=0.0006). Offensively, there was a reduction in power ratings for wide receivers, running backs, and tight ends, respectively. Defensively, there was a reduction in power ratings for linebackers, cornerbacks, and defensive tackles. 31% of NFL players who sustained an Achilles tendon rupture did not return to play in the NFL. On average, players had an over 50% reduction in their power ratings following such an injury.
