The AO/OTA classification for diagnosing femoral trochanteric fractures (31A fractures) was revised in 2018. No studies have investigated whether the addition of CT to radiographic diagnosis improves the inter-rater reliability of classifying 31A fractures with the current AO/OTA criteria. The study aimed to test the hypothesis that the addition of three-dimensional CT (3D-CT) to radiographic diagnosis would improve diagnostic reliability. ⋯ The current AO/OTA classification revised in 2018 provided fair reliability in diagnosing femoral trochanteric fractures in all three surgeon groups. The addition of 3D-CT to radiographic image evaluation improved reliability in high- and middle-expertise groups. The addition of 3D-CT to radiographic evaluation often improved the diagnostic reliability for unstable fractures, although there was some variation among fracture subgroups.

Vertical femoral neck fractures (VFNFs) are one of the most difficult fractures to stabilize, with high non-union (17%), avascular necrosis (AVN, 21%), and femoral neck shortening (FNS, 29.0%) rates. The objective of this investigation was to directly compare the long-term clinical complication rates of VFNFs repaired by crossed (Alpha fixation) or parallel screws in non-geriatric patients. ⋯ For the treatment of VFNFs, satisfactory reduction still remains the key surgical goal that prevents NU, while the incidence of AVN strongly depends on the initial displacement at the time of injury. Crossed screws were associated with a markedly lower FNS rate than parallel screws, which promote further randomised controlled trials to establish a guideline for optimal fixation selection in VFNFs.
