11) An engaging Hill-Sachs defect
, often in coexistence with a Bankart lesion, is also an indication for the procedure.
Equal incidence of detection of hill-sachs defect
was found on conventional MRI and MR arthrography in our study.
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.
