Background: Distal fibular fractures are extremely common, yet there remains controversy about which type of plating technique is the most appropriate. We aimed to compare clinical and biomechanical outcomes following posterior antiglide plating and lateral neutralization plating for Weber B distal fibular fractures.
Methods: A systematic review and meta-analysis of the literature was conducted by two independent reviewers according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We included all comparative studies of distal fibular fracture fixation with either a posterior antiglide plate or a lateral neutralization plate. Our primary outcome of interest was reoperation for hardware removal. Secondary outcomes included hardware discomfort, peroneal tendon irritation, infection, wound complications, and mechanical torque to failure.
Results: A total of 1122 patients with Weber B ankle fractures were included across nine eligible clinical studies, and 76 cadaveric ankles were subject to testing across three eligible biomechanical studies. Meta-analyses revealed a two-fold greater odds of requiring removal of hardware in the lateral plating group compared to the posterior plating group (odds ratio [OR] 2.48, 95% CI 1.58 to 3.91, < .0001), and a three-fold greater odds of experiencing hardware discomfort in the lateral plating group compared to the posterior plating group (OR 2.96, 95% CI 1.83 to 4.80, < .0001). There were no significant differences in rates of peroneal tendon irritation, infection, wound complications, operative time, and torque to failure when comparing the two plating methods.
Conclusion: The results of this review indicate that using posterior antiglide plating for distal fibular Weber B-type fractures is associated with significantly fewer reoperations due to hardware complications and less hardware discomfort compared to lateral neutralization plating. This technique does not appear to increase the risk of peroneal tendon irritation or increase operative time.

The paper presents a detailed gross anatomical description of the elements of the pelvic limb in the African green monkey and provides comparative and differential elements on pelvic limb monkey osteology. The osteometric investigation adds value to the gross morphological and radiological investigation, adjoining metric data to the gross descriptive data set. The main methodology used was the gross morphological investigation, doubled by regular osteometrical and radiographical assessments.

Background: Bosworth fractures (BFs) with entrapment of a fibular fragment behind the posterior malleolus (PM) are rare but potentially serious injuries to the ankle. Despite an increased awareness through a more regular use of computed tomography (CT) scanning, there is still a scarcity of clinical outcome studies.
Methods: Over a course of 25 years, data on 23 patients treated for BF at our institutions (mean age 44 years) were collected prospectively.
Case Report: Metastatic involvement of the acromioclavicular joint in a patient with papillary carcinoma of the ureter.

Ureteral papillary carcinoma is a rare subtype of urothelial carcinoma, ranking fourth among cancers following prostate (or breast) cancer, lung cancer, and colorectal cancer. Although previous studies have documented bone metastases mainly in the pelvis, spine, ribs, and femur, this case report presents the first recorded instance of metastasis occurring in the acromioclavicular joint. A 62-year-old woman with a history of left flank pain and macroscopic hematuria underwent a left nephroureterectomy, which revealed ureteral papillary carcinoma.

Background: Acute ankle sprains are among the most common injuries in children and are often associated with chondral avulsion fractures and ligament injuries. However, radiography may not be sufficiently accurate for assessing cartilage and ligament injuries in children. The primary purpose of this study was to evaluate the necessity of radiography in the diagnosis of acute ankle sprains in children.

The fibula, despite being traditionally overlooked compared to the femur and the tibia, has recently received attention in primate functional morphology due to its correlation with the degree of arboreality (DOA). Highlighting further fibular features that are associated with arboreal habits would be key to improving palaeobiological inferences in fossil specimens. Here we present the first investigation on the trabecular bone structure of the primate fibula, focusing on the distal epiphysis, across a vast array of species.
