CT-based and morphological comparison of glenoid inclination and version angles and mineralisation distribution in human body donors

Table 1 Grading score of 3D-CT scans of the gleno-humeral joint

Points	Kellgren-Lawrence Score [25]	Samilson and Pietro Classification [44]	Larsen Classification [30]
0	absence of signs of osteoarthritis	no exostosis	normal conditions, marginal bone deposits
1	definite osteophytes and possible joint space narrowing	inferior humeral and/or glenoid exostosis < 3 mm in height	definite early abnormality, erosion and joint space narrowing present
2	moderate multiple osteophytes, definite narrowing of joint space, some sclerosis	inferior humeral and/or glenoid exostosis measuring 3–7 mm, and slight gleno-humeral irregularity	medium to severe destructive abnormality, erosion and joint space narrowing present
3	large osteophytes, marked narrowing of joint space, severe sclerosis	inferior humeral and/or glenoid exostosis measuring > 7 mm, gleno-humeral joint narrowing and sclerosis	mutilating abnormality, gross bony destruction, dislocation and ankylosis
Maximum 9 points	Maximum 3 points	Maximum 3 points	Maximum 3 points

Established osteoarthritis classifications were considered [25, 30, 44]. Grade 0: no osteoarthritis signs, grade 1: 1–2 points, grade 2: 3–4 points, grade 3: 5–7 points, grade 4: 8–9 points
