Reconsidering “Critical” Bone Loss in Shoulder Instability: 17-Year Follow-Up Study following Arthroscopic Bankart Repair

Figure 1

Measurement of glenoid bone loss in the dislocated shoulder in comparison to the contralateral unaffected side (Griffith Index). On the affected side (a), the maximum width at right angles to the long axis is 24.2 mm. On the unaffected side (b), the maximum width of the glenoid is 28.0 mm. The difference (28 mm − 24.2 mm) is 3.8 mm. As 3.8 mm/28.0 mm × 100 = 13.6%, this patient has 13.6% glenoid bone loss.
