Treatment of fractures around the foot and ankle can be challenging in patients who are unable to remain non weight bearing on their lower extremity. Traditional implants are not sufficient to resist loads incurred during weight bearing and can also lead to complications related to wound healing and infection. We describe a technique for fracture fixation of the foot and ankle that uses low profile implants to minimize soft tissue insult combined with multiplanar external fixation to allow for immediate weight bearing.

Purpose: While treatment modalities for Maisonneuve fractures involving the proximal third of the fibula are established, no studies to date have reported outcomes associated with syndesmotic-only fixation of middle third fibular shaft fractures. The purpose of this study was to evaluate outcomes associated with syndesmotic-only fixation in the treatment of Maisonneuve fractures involving the middle third of the fibula.
Methods: A retrospective review was conducted on 257 cases of syndesmotic ankle instability with associated fibular fractures at a level 1 trauma center between 2013 and 2023.

Background: This study investigated the effect of various offloading devices commonly used for the management of diabetic foot ulcerations on peak plantar pressure and pressure-time integral of the contralateral limb.
Methods: A quantitative, randomised and within-subject repeated measures study was conducted in an outpatient gait laboratory. Outpatients with unilateral diabetic foot ulcers and adequate perfusion to the lower limb without an intrinsic limb-length discrepancy who were able to walk were recruited for the study.

The water-lubricated bearing plays a crucial role in the ship propulsion system, significantly impacting vessel safety. However, under the harsh working conditions of low-speed and heavy-load, the lubrication state of water-lubricated bearings is usually poor, leading to serious friction and wear. To improve the tribological performance of composites and reduce friction, three short fibers (ultra-high-molecular-weight polyethylene fibers, basalt fibers, and bamboo fibers) with the same mass fraction (5%) were added into the melted thermoplastic polyurethane (TPU).

A collagen-inspired helical protein-mimic has been synthesized via topochemical polymerization of a designed tripeptide monomer. In the monomer crystal, molecules arrange in a head-to-tail manner, forming supramolecular helices. The azide and alkyne of adjacent molecules in the supramolecular helix are proximally preorganized in a ready-to-react arrangement.

Background: Hip morphology variations, particularly in femoral neck shaft angle (NSA) and iliac wing width (IWW), have been associated with gluteal tendinopathy. However, the biomechanical implications of these morphological differences on gluteal muscle function are not well understood. This study investigates how NSA and IWW influence gluteal muscle forces, moment arms, and estimated tendon loads during walking, aiming to provide insights into the potential biomechanical pathways that may contribute to altered lateral hip loading patterns.
