Background:
The acute lateral ankle sprain accounts for 85% of all sprains. The
lateral sprain associated with other ligament injuries, such as medial and syn-
desmosis sprain. In the long-term approximately 20% of the acute lateral sprain
develops chronic lateral ankle instability (CLAI). The definition of the chronic an-
kle instability is persistent pains, repeatedly ankle sprains and episodes of ankle
giving away.
Purpose / Aim of Study:
The aim of this study was to correlate the clinical
examination to ultrasonography (US) after ankle sprain.
Materials and Methods:
Through 15 october to 26 november 2016 patients
who were diagnosed with an ankle sprain were included. We evaluated with high
frequency (15-6 MHz) ultrasonography the lateral ligament injury (anterior
talofibular ligament (ATFL), calcaneofibular ligament (CFL), syndesmosis (ante-
rior intertibiofibular ligament (AiTFL)) injury) and medial ligament injury (deep
posterior tibiotalar ligament (dPTL), tibiocalcaneal ligament (TCL)).
Findings / Results:
16 women and 10 men and the mean age was 26.7 years,
and the mean BMI was 26.6 (17.2-41.3) participated. Two clinical signs statis-
tically correlated with US and multiple logistic regression analysis confirmed the
results. The US confirmed ATFL partial rupture and normal CFL. Positive palpated
tenderness AiTFL predicted with partial ruptured ATFL and secondly reported
pain during active plantar flexion of ankle predicted with normal confirmed US
CFL.
Conclusions:
The study predicted patients with partial rupture of ATFL clini-
cal present with tenderness at AiTFL point and patients presented with intact
CFL reported pain during active plantar flexion. The overall clinical signs and
physical examinations were unreliable factors to predicate lateral (ATFL, CFL),
syndesmosis injuries (AiTFL) and medial ligament injuries compared with the US
findings.
