Pathophysiology of ankle sprain

Ankle sprain is a very common injury in the population (athletes and non-athletes) that affects the ligament complex of said joint and can often cause great dysfunction if not properly treated.

The ligaments They are multidirectional fibers of connective tissue whose purpose is to provide stability to a joint and which, after being subjected to excessive tension beyond the physiological joint range, lose their structure, becoming more lax and not being able to generate said stability.

In the case of the ankle, the external or lateral ligaments are the ones that are most injured, being the anterior talofibular ligament (LPAA) the most affected, followed by calcaneal peroneal ligament (LPC) and finally the posterior talofibular ligament (LPAP). The injury mechanism This structure consists of a movement of forced investment.

However, we must not forget the internal compartment of the foot or deltoid ligament, which is less frequent (10%) but can also be injured; in this case by a mechanism of forced eversion.

As risk factors Some of the factors that could compromise the ankle include muscle strength deficits, variations in the plantar arch, obesity, gait biomechanics, inadequate warm-up and training, or poor physical conditions.The author

To diagnose it, it would be advisable to do it through a radiography in charge, by means of magnetic resonance imaging, CT scan I ultrasound.

The physical examination can also lead us to assess the severity of injury through different clinical signs that will help us determine the degree of the sprain:

CLINICAL SIGNS

MILD SPRAIN

(Grade I)

MODERATE SPRAIN

(Grade II)

SEVERE SPRAIN

(Grade III)

Location of pain LPAA LPAA, LPC LPAA, LPC, LPAP
Edema and Hematoma Local and unremarkable Local and quite remarkable Diffuse (several parts of the ankle) and very noticeable
Load capacity Complete or partial Difficult and with crutches Total functional disability
Ligamentous Damage Elongation Partial rupture Total breakup
Instability Does not present Scarce Total

Once the degree of sprain we are facing has been determined, treatment We will divide it, depending on the objective, into 4 phases: 

PHASE I: Reduce inflammation and pain.

PHASE II: Joint mobilization.

PHASE III: Potentiation and proprioception.

PHASE IV: Functional rehabilitation to the sports gesture.
