Article Synopsis
  • Rotational malformation is a common complication after intramedullary nailing of intertrochanteric fractures, and it can be hard to detect since imaging only assesses certain planes, not the rotational alignment.
  • This study examined 74 patients using postoperative CT scans to evaluate hip anteversion and identify correlations with patient or fracture characteristics.
  • Results showed that 31.1% of patients had significant rotational deformity, with unstable fractures being linked to worse rotational alignment outcomes.

Investigating the potential benefits of the use of magnetic fields in inertial confinement fusion experiments has given rise to experimental platforms like the Magnetized Liner Inertial Fusion approach at the Z-machine (Sandia National Laboratories) or its laser-driven equivalent at OMEGA (Laboratory for Laser Energetics). Implementing these platforms at MegaJoule-scale laser facilities, such as the Laser MegaJoule (LMJ) or the National Ignition Facility (NIF), is crucial to reaching self-sustained nuclear fusion and enlarges the level of magnetization that can be achieved through a higher compression. In this paper, we present a complete design of an experimental platform for magnetized implosions using cylindrical targets at LMJ.
