An aneurysmal bone cyst is a locally destructive lesion considered to be a pseudotumor arising from the bone. Although this benign-like lesion is generally considered rare, several approaches for treatment have been presented. We report a case involving a 15-year-old female diagnosed with aneurysmal bone cyst of the lateral malleolus. Applying the Masquelet technique enabled the treatment of the lesion without causing instability to the ankle joint and the prevention of recurrence through the application of polymethylmethacrylate. To our knowledge this is the first documented case in our region and possibly in the Philippines.
<p class="abstract">Tranexamic acid (TXA) has been used successfully in the practice of orthopedics to reduce perioperative blood loss, particularly in total hip and knee arthroplasty and spine surgery. The use of TXA has shown potential to reduce blood loss, transfusion rates and volumes, perioperative hemoglobin change and hospital-related costs at various degrees. This review aimed to evaluate the clinical results of the intraoperative use of TXA in long bone fracture surgeries. Relevant electronic articles were reviewed through a systematic search and selection process, resulting in the selection of five randomized control trials with a total of 295 participants. These studies compared the primary outcome of this meta-analysis, which was blood loss. Four of the studies included post-operative hemoglobin levels as their outcomes. Furthermore, two studies compared drop in hemoglobin levels, while three studies included blood transfusion events. Results showed a significant difference in terms of total blood loss when intraoperative administration of TXA was compared to placebo in long bone surgeries with a mean difference of -76.94 [-106.62, -47.26] (95% CI) (p≤0.00001). There was no significant difference in terms of post-operative hemoglobin levels (p=0.27) with a mean difference of 0.31 [-0.24, 0.86] (95% CI). No significant difference was also shown between the two groups as to drop in hemoglobin levels (p=0.29) with a mean difference of -0.34 [-0.97, 0.29] (95% CI). This meta-analysis showed that intraoperative use of TXA given during long bone fracture surgeries can effectively reduce total blood loss and reduce risk of transfusion events or avoid transfusion events.</p>
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
