Symptoms of a Lateral Malleolus Fracture include swelling and bruising over the lateral ankle, pain on weight-bearing, walking or hopping, pain when walking on uneven surfaces, and a protruding bone or malaligned foot in severe cases. The incidence rate of this injury appears to be similar between genders, but studies have found that it is more prevalent in females as they age. Lateral Malleolus Fracture Incidence RatesĪ study of 9767 patients with ankle fractures over a period of 9 years found that lateral malleolus fractures are the most common type of ankle fracture, accounting for 55% of all ankle fractures. Due to its position and role in weight-bearing, it is more commonly injured than the medial malleolus. It acts as a weight-bearing structure, absorbing approximately 10% of the weight in standing. The lateral malleolus is a bony prominence on the fibula that sits on the outside of the ankle joint. The talus is a small bone that sits on top of the heel bone, and it forms the lower part of the ankle joint. The fibula runs parallel to the tibia, on the outside of the leg. The tibia and fibula are long bones in the lower leg, with the tibia being the larger of the two. The ankle joint is comprised of three bones: the tibia, the fibula, and the talus. In this article, we will discuss the anatomy of the ankle joint, the various types of Lateral Malleolus Fractures, as well as the conservative and surgical treatment options available for this condition. These fractures are often caused by traumatic events such as falls or trips, but can also result from overuse injuries or poor biomechanics. Conclusion: Pneumatic orthopedic boot use is associated with good ankle functionality in patients with stable Weber B type isolated lateral malleolus fracture.Lateral Malleolus Fractures are the most common type of ankle fracture, accounting for approximately 55% of all ankle fractures. As well as, greater residual pain in those with surgical intervention. 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). The mean FAAM score was 80.6 points and the mean OMA score was 93.4 points. 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). 23 patients (52.2%) were treated with a boot and 21 (47.7%) were treated surgically. 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. 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. 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. Isolated lateral malleolus fractures represent a significant percentage of them, with surgical treatment being the usual one. Orthopedic boot, Walker boot, ankle fracture, Weber B, lateral malleolus fracture, fibula fracture.Īnkle fractures are one of the most common limb bone injuries of all ages, with a prevalence up to 75% in the productive stage.
