Diagnostic Accuracy of MRI in the Measurement of Glenoid Bone Loss

Abstract: Glenoid bone loss can be accurately measured on MRI using the circle method. The MRI quantification of glenoid bone loss compares favorably to measurements obtained using 3D CT and CT. The accuracy of the measurements correlates with the level of training, and a learning curve is expected before mastering this technique.

“…fractures, rotator cuff injuries, superior labrum anteroposterior and anterior labral periosteal sleeve avulsion). Defect sizes for Bankart lesions were measured using the Gyftopoulos circle method 16 and graded using Itoi's classification. 17 Hill-Sachs lesions were measured using the modified Cetik method 9 ( Figure 1) and were classified according to the Calandra classification.…”

“…A study of 18 cadavers revealed that the accuracy of MRI in measuring glenoid defects was comparable to CT. They used the "best circle" method previously described and applied the technique to MR [40] . Moroder et al [41] however compared CT with MRI in 83 patients in the pre-operative planning stage to evaluate bone defects in shoulder instability and reported that CT was found to be superior in their study.…”

“…On the other hand, these results can be used to assess the shoulder instability. Gyftopoulos et al [4] indicated that a similar result of a bone defect can be acquired using circle-center way in CT, 3D CT, and MRI, but it requires significant time for analysis. The 3D measurement method also requires a high level of skill from the operator of the computer software who is familiar with the anatomic structure, and involves a higher learning curve.…”

“…Based on the 3D measurement of normal shoulder, such visualization will provide evidence for shoulder instability and help choose a suitable surgical procedure. The glenoid track is a concept that can be used to evaluate a defected humeral head and glenoid at the same time, which was reported by Yamamoto et al [3] and Gyftopoulos et al [4]. Burkhart et al [1,5] measured the center of the glenoid by arthroscopy, but he pointed out that the arthroscopic method has its limitations and it allows the quantification of bone defects in the glenoid.…”
