Perilunate fracture dislocations (PLFDs) are uncommon, usually resulting from high-energy trauma. Several classification systems describe the patterns of injury seen, but there is still significant variation and patterns of injury that do not fit within these classifications continue to be described. Carpal coalitions are rare, mostly asymptomatic, and are, as a result, usually identified incidentally.

- Scapholunate instability (SLI) is the most prevalent type of carpal instability, potentially leading to a degenerative condition known as scapholunate advanced collapse (SLAC), and it can be difficult to diagnose in its early or dynamic stages.
- Diagnosis techniques include CT and MR arthrograms, dynamic fluoroscopy, and the gold standard of arthroscopy, while treatment varies based on the stage of injury—acute cases may benefit from repair within 6 weeks, while chronic cases often require reconstruction.
- Current trends in surgical techniques favor less invasive approaches that maintain nerve supply to wrist structures, and successful rehabilitation emphasizes specific muscle strengthening after immobilization, with a collaborative team approach.
Axial loading of the foot/ankle complex is an important injury mechanism in vehicular trauma that is responsible for severe injuries such as calcaneal and tibial pilon fractures. Axial loading may be applied to the leg externally, by the toepan and/or pedals, as well as internally, by active muscle tension applied through the Achilles tendon during pre-impact bracing. The objectives of this study were to investigate the effect of Achilles tension on fracture mode and to empirically model the axial loading tolerance of the foot/ankle complex.
