Recognition and proper management of Hill-Sachs lesions is important because bone loss on the humeral head can alter the biomechanics of the glenohumeral articulation and can contribute to instability.
Restoration of a single concavity may also increase the surface area of the glenohumeral articulation, decreasing joint pressure, he said.
Ultimately, if left untreated, these soft-tissue imbalances about the glenohumeral articulation result in secondary subluxation or dislocation and even a fixed articular deformity of both the glenoid and humeral head and overgrowth of the coracoid.
The goals of treatment always include restoration of full passive range of motion, maintenance of a concentric, stable glenohumeral articulation, and muscle rebalancing in order to facilitate glenoid remodeling.
An increase in scapulothoracic motion may compensate for restricted motion at the glenohumeral articulation.
Additionally, the glenohumeral articulation is less conforming than the hip joint, and restricted shoulder motion can be compensated by surrounding joints.
The shallow ball-and-socket glenohumeral articulation is deepened by increased glenoid articular cartilage thickness at its periphery (2) and the glenoid labrum.
