Introduction[edit | edit source]
- Ankle sprains are one of the most common musculoskeletal injuries, being the most frequent musculoskeletal trauma among athletes.
- Most of these injuries are successfully treated conservatively; however, up to 70% of patients can develop long-lasting symptoms. Therefore, understanding prognostic factors for an ankle sprain could help clinicians identify patients with poor prognosis and choose the right treatment.
- A suggested approach will be presented in order to positively identify the factors that should warrant a more aggressive attitude in the initial conservative treatment.
- There are some prognostic factors linked to a better recovery and outcome; nevertheless, prognostic factors for full recovery after initial ankle sprain are not consistent.
Clinically Relevant Anatomy[edit | edit source]
Of the lateral ankle ligament complex the most frequently damaged one is the anterior talofibular ligament (ATFL). Their anatomical location and the mechanism of sprain injury mean that the calcaneo-fibular (CFL) and posterior talofibular ligaments (PTFL) are less likely to sustain damaging loads.
On the medial side the strong, deltoid ligament complex [posterior tibiotalar (PTTL), tibiocalcaneal (TCL), tibionavicular (TNL) and anterior tibiotalar ligaments (ATTL)] is injured with forceful "pronation and rotation movements of the hindfoot"[1]
The stabilising ligaments of the distal tibio-fibular syndesmosis are the anterior-inferior, posterior-inferior, and transverse tibio-fibular ligaments, the interosseous membrane and ligament, and the inferior transverse ligament. A syndesmotic ankle sprain occurs with combined external rotation of the leg and dorsiflexion of the ankle.
Mechanism of Injury[edit | edit source]
Predisposing Factors[edit | edit source]
Predisposing factors are the risk factors for lateral ankle sprains and they are divided into two categories:intrinsic and extrinsic.[2]
Lateral ankle sprains usually occur during a rapid shift of body center of mass over the landing or weight-bearing foot. The ankle rolls outward, whilst the foot turns inward causing the lateral ligament to stretch and tear. When a ligament tears or is overstretched its previous elasticity and resilience rarely returns. Some researchers have described situations where return to play is allowed too early, compromising sufficient ligamentous repair.[3]
Reports have proposed that the greater the level of plantar flexion the higher the likelihood of sprain[4]
Yeung et al, 1994, in an epidemiological study of unilateral ankle sprains, reported that the dominant leg is 2.4 times more vulnerable to sprain than the non-dominant one.[5][6]
A less common mechanism of injury involves forceful eversion movement at the ankle injuring the strong deltoid ligament.
