Purpose: The anterolateral distal tibial rim (anterior malleolus, AM) is frequently fractured in malleolar fractures. The aim of this study was to evaluate the medium-term outcomes of malleolar fractures involving the AM.

Methods: Among 100 patients with AM fractures that were treated over a 10-year period, 50 patients were available for follow-up.

Aims: The treatment of ankle fractures and fracture-dislocations involving the posterior malleolus (PM) has undergone considerable changes over the past decade. The aim of our study was to identify risk factors related to the occurrence of complications in surgically treated ankle fractures with PM involvement.

Patients And Methods: We retrospectively analyzed 300 patients at a mean age of 57 years with 300 ankle fractures involving the PM treated surgically at our institution over a 12-year period.

Introduction: The presence of a posterior malleolar (PM) fragment has a negative prognostic impact in ankle fractures. The best treatment is still subject to debate. The aim of this study was to assess the medium-to-long-term clinical and functional outcome of ankle fractures with a PM fragment in a larger patient population.

The anterolateral tibial rim with the anterior tibial tubercle (Tubercule de Tillaux-Chaput) serves as an insertion site of the anterior inferior tibiofibular ligament (AITFL). It can also be termed the anterior malleolus or fourth malleolus. Fractures of the anterolateral tibial rim typically result from an external rotation or abduction mechanism of the talus within the ankle mortise.

Article Synopsis
  • Accessing aldehydes from carboxylate compounds is usually tough, but carboxylate reductases (CARs) can simplify the process in one step without over-reducing to alcohols.
  • The production of CARs can be tricky due to issues with protein solubility, which affects their study and use.
  • Optimizing the production of NoCAR from Nocardia otitidiscaviarum through better growing conditions and using E. coli tuner cells resulted in a significant increase in activity, allowing effective conversion of sodium benzoate to benzaldehyde in a short time frame.

We present a technique of fixation of trimalleolar fractures with additional fracture of the anterior tibial tubercle ("quadrimalleolar") or anterior fibular rim ("quadrimalleolar equivalent"). Twenty-four patients with a mean age of 60 years were treated with open reduction and internal fixation of all 4 malleoli. There were 17 quadrimalleolar and 6 quadrimalleolar equivalent fractures.
