Measuring RUI
ML rads:
-Brunnberg 1999: Traditional RU step
-Proks VS 2011: Humeroulnar subluxation index (circles of humeral condyles and ulnar trochlear notch)
-Lappalanien JSAP 2016:Humeroulnar joint space
-Burton JSAP 2017: Best fit circle superimposition technique of trochlear notch vs radial head - sens 86%, spec 77% - is a simplification of Eljack’s work
-Mostafa VCOT 2019: Modified RU step; caudal humeroradial distance minus distal humeroulnar distance
Pulkkinen VRU 2020:
-Novel RUI grading using rads in chondrodystrophic breeds (Lappalainen)
Rohwedder VCOT 2021:
-Static and dynamic axial RUI measured using sphere fitting technique (Eljack VS 2013 - most sens and spec 95% and 90%)
-Static RUI sig diff in control vs MCD elbows
-Control elbows had diff bwt static and dyanmic RUI at walk
-MCD elbows had no difference -> perhaps CT measurement of static RUI are comparable to in vivo situation during walk??)
Griffon VCOT 2018:
-RUI diagnosed 26% rads, 80% CT
-Rads and CT poor-fair agreement with arthroscopy
Baud JSAP 2020:
-No difference in static RUI between RI or apical FMCP
Wennemuth VCOT 2020
Rads vs CT for MCD
Rads 84% sens 84% spec vs CT
Humphreys AJVR 2022
Attenuation of MCP
Attenuation reduced with MCP
No sig diff in attenuation categories based on MOS
Soares JSAP 2022
Apical vs RI
Humeral condyles (med and lat) higher HU in apical FMCP
Medial humeral condyle may be a/w pathogenesis for apical but not RI FMCP
Jacqmin VCOT 2023
U/S for MCD - high freq linear transducer 12-18Hz
joint effusion, abnormal shape
may be helpful to confirm MCD before arthroscopy
Garnier NZVJ 2023
needle arthroscope 1.9mm 0 deg
success in removing FMCP
Ellis VCOT 2024
HU in humeral condyle and MCP
Labs have sig higher min and max HU - asymptomatic
