The mechanisms underlying AFF remain unclear, with hypotheses including bone turnover suppression and morphological variation. Recent studies have suggested a potential genetic susceptibility to AFF. A scoping review was conducted using PubMed to identify studies published since 2016. ⋯ Histomorphometric studies supported the hypothesis of bone turnover suppression in AFF, with alterations in tissue mechanical properties and microarchitecture observed, particularly in cortical bone. The findings suggest a potential genetic susceptibility to AFF, with variants in GGPS1 and CYP1A1 genes affecting osteoblast and osteoclast function. Bone turnover suppression and altered tissue properties contribute to the pathogenesis of AFF.

Modern osteosynthesis of periarticular fractures: The role of provisional fixation revisited.
Periarticular fractures are complex injuries affecting the joint articular surface, the subchondral area, the metaphyseal region, the surrounding soft tissue envelope and not infrequently the ligamentous structures. The management of these injuries has evolved over the years, from one stage to two stage procedures thus facilitating soft tissue resuscitation, adequate pre-operative planning and the use of biologics optimizing the conditions for definitive fixation for a successful long-term outcome. ⋯ Herein, the role of provisional fixation as well as strategies on how they should be applied are discussed. The aim is to revisit this important step of provisional fracture fixation since its introduction by Albin Lambotte, in the early 1900's.
