Ankle injuries are the most common sport-related injuries. To date, no studies have been published that use national data to present a cross-sport, cross-sex analysis of ankle injuries among US high school athletes.
To investigate the incidence rates of ankle injuries by sex, type of exposure, and sport.
Descriptive epidemiologic study.
One hundred US high schools.
United States high school athletes.
We reviewed ankle injury data collected over the 2005-2006 school year from a nationally representative sample obtained by High School RIO, an injury surveillance system. Specific sports studied were boys' football, boys' and girls' soccer, girls' volleyball, boys' and girls' basketball, boys' wrestling, boys' baseball, and girls' softball.
An estimated 326 396 ankle injuries occurred nationally in 2005-2006, yielding an injury rate of 5.23 ankle injuries per 10 000 athlete-exposures. Ankle injuries occurred at a significantly higher rate during competition (9.35 per 10 000 athlete-exposures) than during practice (3.63) (risk ratio = 2.58; 95% confidence interval = 2.26, 2.94; P < .001). Boys' basketball had the highest rate of ankle injury (7.74 per 10 000 athlete-exposures), followed by girls' basketball (6.93) and boys' football (6.52). In all sports except girls' volleyball, rates of ankle injury were higher in competition than in practice. Overall, most ankle injuries were diagnosed as ligament sprains with incomplete tears (83.4%). Ankle injuries most commonly caused athletes to miss less than 7 days of activity (51.7%), followed by 7 to 21 days of activity loss (33.9%) and more than 22 days of activity loss (10.5%).
Sports that combine jumping in close proximity to other players and swift changes of direction while running are most often associated with ankle injuries. Future research on ankle injuries is needed to drive the development and implementation of more effective preventive interventions.

    ABSTRACT: Sprain of the ankle is undoubtedly a common injury during athletic activity, and the sprain can be also associated with fracture of the ankle. Isolated posterior malleolus fracture is a very rare condition, which is usually missed. Here, we are presenting a 37 years old female patient, who suffered injury secondary pressing on brake pedal during collision in a traffic accident. Clinical evaluation is based on Ottawa Ankle Rules and a fracture is diagnosed; patient is started on daily activities at postoperative Week 8. This study aims to emphasize that Ottawa Ankle Rules are usually efficient for evaluating fractures of ankle, but clinicians should always make a detailed physical examination.

    ABSTRACT: The incidence of osteochondral lesions (OCLs) in association with displaced ankle fractures has only been examined in two previous studies. In both studies magnetic resonance imaging (MRI) was performed prior to open reduction and internal fixation (ORIF). Because MRI may overdiagnose or overestimate the extent of OCLs in an acute trauma setting the aim of this study was to determine the incidence of OCLs after ORIF of displaced ankle fractures using MRI at medium-term follow-up, and to analyse if the severity of fracture or the clinical outcome correlates with the incidence of OCLs.

    • "Ankle sprains are the most common injury incurred during sports activities (Collins, Teys, & Vicenzino, 2004; Morrison & Kaminski, 2007) and it has been reported that during the period from 2005 to 2006 ankle sprains accounted for 22.6% of all sports injuries in adolescent high school athletes (Nelson, Collins, Yard, Fields, & Comstock, 2007). It is estimated that between 20% and 40% of ankle sprains will result in chronic ankle instability (CAI) with up to 70% reported in specific sports such as basketball (Valderrabano, Wiewiorski, Frigg, Hintermann, & Leumann, 2007; Valderrabano et al., 2006).

    ABSTRACT: Free download until 18 fer, 2015 in,XMZM2EIs Objective To compare the effect of two manual therapy techniques, mobilization with movement (WB-MWM) and talocrural manipulation (HVLA), for the improvement of ankle dorsiflexion in people with chronic ankle instability (CAI) over 48 hours. Design randomized controlled clinical trial. Setting University research laboratory. Participants Fifty-two participants (mean±SD age, 20.7±3.4 years) with CAI were randomized to WB-MWM (n=18), HVLA (n=19) or placebo group (n=15). Main Outcome Measures weight-bearing ankle dorsiflexion measured with the weight-bearing lunge. Measurements were obtained prior to intervention, immediately after intervention, and ten minutes, 24 hours and 48 hours postintervention. Results There was a significant effect x time (F4,192=20.65; P<.001) and a significant time x group interactions (F8,192=6.34; P<.001). Post hoc analysis showed a significant increase of ankle dorsiflexion in both WB-MWM and HVLA groups with respect to the placebo group with no differences between both active treatment groups. Conclusion A single application of WB-MWM or HLVA manual technique improves ankle dorsiflexion in people with CAI, and the effects persist for at least two days. Both techniques have similar effectiveness for improving ankle dorsiflexion although WB-MWM demonstrated greater effect sizes.
