[Factors associated with functionality in patients with closed ankle fracture].

Background: Ankle fractures are among the most frequent fractures in the lower limb, predominantly affecting young people and representing approximately 9% of all fractures.

Objective: To identify the factors associated with functionality in patients with closed ankle fracture.

Material And Methods: Observational and retrospective study. Records of people with a diagnosis of ankle fractures admitted to rehabilitation between January to December 2020 in a Physical Medicine and Rehabilitation Unit of a third level hospital were included. Age, sex, body mass index (BMI), days of disability, mechanism of injury, type of treatment, length of stay in rehabilitation, type of fracture and functionality were captured. Chi-squared and Student's t test were used to determine the association. Subsequently a multivariate analysis with binary logistic regression was performed.

Results: The average age of the subjects was 44.8 years, the female sex was presented in 54.7%, the average BMI was 28.8%, 66% carried out a paid work activity, 65% received surgical treatment, the average time of disability was 140 days, the factors associated with functionality independently were age, pain, dorsiflexion and plantar flexion upon admission to rehabilitation.

Conclusions: Ankle fractures occur in a young population and the factors associated with functionality were age, dorsiflexion, plantar flexion, and pain upon admission to rehabilitation.
