SHO, PAUL, ERHO, CUE

Question 1

SHO

Answer 1

Fitz 2009: 5% major complications a/w failure bone/implant
Quinn 2014: Does not improve unloading, infilling, OA
Fitz 2015: stepped plate, 80% success, no major complications
Wendelberg 2014: 90% owners felt improvement, 10% comp

McCartney 2023: plate/rod SHO all success

Question 2

PAUL

Answer 2

Coghill 2021: PAUL no benefit (CBPI) over FMCP removal alone
Danielski 2022: 18% major comp - 9% nonunion, implant failure distal screw, proximal screw, infection) - 10% implant removal
Vezzoni 2018: 90% acceptable fx, 4% plate removal
Ballester 2022: 70% owners satisfied, 12% major comp (delayed union, implant failure, OA)

Question 3

ERHO + medial OWO

Crystal VCOT 2024
Ex vivo study

Answer 3

Osteotomy at 75% of humerus more effective at reducing medial load than proximally

OWO more effective than external rotational osteotomies - but both reduced medial compartment load

Question 4

CUE

Cook CVJ 2015

Answer 4

10% major, 1% catastrophic

10% unacceptable fx
