Purpose: The goal of our study was to determine whether a bone tamp could be used to correct
a Hill-Sachs lesion by a unique technique that we developed termed “humeroplasty.”
Type of Study: In vitro cadaveric study. Methods: We created reproducible Hill-Sachs lesions in 14 cadaveric humerii, which we then
reduced with a curved bone tamp using our proposed technique. Paired t tests, with the significance set at P < .05, were then used to compare the prereduction and postreduction depths, widths,
lengths, and volumes of the lesions. Results: The average prereduction defect measurements were 8.9 mm deep, 16.3 mm wide, 24.1
mm long, and 1,755 mm3 in volume. The average postreduction defect measurements were 1.6 mm deep, 6.2 mm
wide, 10.4 mm long, and 50.3 mm3 in volume. A statistically significant improvement (P < .001) was seen in all parameters. Conclusions: Our technique was able to consistently and significantly restore all measured parameters
of the Hill-Sachs lesions using a curved bone tamp. This reduction to a “small” defect
may reduce the higher rate of recurrence normally found with the surgical treatment
of shoulder instability when “large” Hill-Sachs lesions are present. Clinical Relevance: Humeroplasty potentially might reduce the higher rate of recurrence observed when
the surgical treatment of shoulder instability involves the presence of large Hill-Sachs
lesions.
