High ankle sprain in field hockey
Ankle sprains are not the first injury that comes to mind when you think about injuries in field hockey. The lateral ankle sprain, often seen in basketball and soccer is indeed not very common in field hockey, mostly because of the
Mechanism of injury
HAS happens when the ankle makes a forced external rotation (2). A few mechanisms can explain such movement :
– The athlete pivots towards the inside while the foot stays planted in the ground
– A contact with another player causes an inward movement of the knee while the foot stays planted in the ground
– A fall on the leg while the foot is stuck in an external rotation under the player
In field hockey, the skate actually increases the risk for this type of injury due to the way the skate limits movement in the ankle to absorb an impact, along with the high risk of collision that comes with this sport.
The signs and symptoms associated with HAS are :
– Incapacity or difficulty of bearing weight on the injured foot
– Increased pain in ankle movements, especially in dorsiflexion (pulling toes towards the sky)
– Pain when touching the ligament
– Variable swelling depending on the gravity of the related injuries like a fracture or another affected ligament
Many tests exist to evaluate the HAS, but most of them are not completely reliable. The
1. Acute phase
This phase consists of protecting the ankle, minimising pain, inflammation, muscle atrophy and loss of range of motion. Taping, ice, mobility and mild strengthening exercises are used to
2. Subacute phase
This phase consists of normalizing the mobility, strength and general function of the athlete. Mobility, more advanced strengthening, proprioceptive and balance exercises are included in that phase and must be executed without pain. Swimming and other transfer activities can be useful to maintain cardiovascular function. When the player can jog and jump without pain, he can move on to the next phase.
3. Advanced phase
This phase consists of preparing the return to sport. Slow-to-fast agility, plyometric and sport-specific exercises, executed on many different surfaces should be included in the athlete’s rehabilitation program. The return to sport should be done when the player can execute sport-specific movements with good control and with little or no pain and feeling of instability.
The duration of the rehabilitation period for HAS is longer than for lateral ankle sprains. For HAS, the rehab averages 6 to 8 weeks while the lateral sprain period is from 3 to 4 weeks (1). This then brings the question: how can you prevent ankle sprains? An interesting study
Even if the guidelines presented in this article are usually used for the treatment of HAS, they should be adapted to the player in terms of his goals, the presentation of his injury and his general physical condition. A healthcare professional is essential to follow-up on the injury to make sure that the athlete progresses as he should be through the phases of his rehabilitation.
