The effect of a combined glenoid and Hill-Sachs defect on glenohumeral stability: a biomechanical cadaveric study using 3-dimensional modeling of 142 patients.
Moderate to large engaging Hill-Sachs defects: an in vitro biomechanical comparison of the remplissage procedure, allograft humeral head reconstruction, and partial resurfacing arthroplasty.
Equal incidence of detection of hill-sachs defect
was found on conventional MRI and MR arthrography in our study.
(11) An engaging Hill-Sachs defect
, often in coexistence with a Bankart lesion, is also an indication for the procedure.
The factors involved in determining the likelihood of engagement of the lesion are the size of the Hill-Sachs defect
and its location.
The Hill-Sachs defect group, overall, performed well with regard to instability: no cases of recurrence were noted.
In general, glenoid defects in the 33% range and Hill-Sachs defects that either engage in a physiological range of motion or are in the 30% to 40% range should be considered for grafting.

They tried to determine the effect of size, orientation, and location of Hill-Sachs defects
with respect to recurrent dislocation.
