ABSTRACT

Ankle fractures are one of the most common limb bone injuries of all ages, with a prevalence up to 75% in the productive stage. Isolated lateral malleolus fractures represent a significant percentage of them, with surgical treatment being the usual one. The objective of this study is to opt for a non-surgical treatment algorithm in patients with stable Weber B type isolated lateral malleolus fractures using a pneumatic orthopedic boot and to analyze short-term functional results. Material and methods: Analytical cross-sectional study conducted from August 2018 to August 2019 in patients with Weber B type isolated lateral malleolus fracture treated with a long Walker-type pneumatic orthopedic boot and follow-up with weight-bearing ankle X-rays on four occasions (1, 2, 6, 12 weeks) to evaluate fracture line alignment, modification of ankle medial clear space and bone healing process. Measurements of OMA, FAAM and AOFAS functional scales were performed by a standardized physician 12 months after the event and the results were compared with a control group treated surgically. Results: 44 patients were included, 26 men (59.1%) and 18 women (40.9%). The mean age was 34.7 years. 23 patients (52.2%) were treated with a boot and 21 (47.7%) were treated surgically. Regarding the assessment of functional scales; for AOFAS the mean score was 89.6 points, classifying 95.5% of the sample as functional (n = 42). The mean FAAM score was 80.6 points and the mean OMA score was 93.4 points. The statistically significant association between the surgical intervention and the instability of the hindfoot in the AOFAS scale stands out (ro = 0.499, p = 0.001). As well as, greater residual pain in those with surgical intervention. Conclusion: Pneumatic orthopedic boot use is associated with good ankle functionality in patients with stable Weber B type isolated lateral malleolus fracture.
