Hill-Sachs

Radiologically the Hill-Sachs compression lesion maybe evident. The Hill-Sachs lesion is a compressive fracture of the humeral head and is an important bony sign of previous anterior shoulder dislocation and instability and is significant more common in adult patients. There may also be an avulsion injury to the glenoid rim indicative of an associated Bankart lesion (detachment of the anteroinferior capsule from the glenoid neck). 

US can detect a variety of minus lesions ranging from small para-articular erosions caused by chronic synovitis to large post-traumatic defects. One of the most common bone defects is the Hill-Sachs lesion, a compressive fracture of the humeral head that follows anterior shoulder dislocation (see Chapter 6). The lesion derives from the traumatic action of the sharp anterior glenoid border against the posterolateral aspect of the dislocated humeral head. US has proved to be an efficient modality to detect a Hill-Sachs lesion and assess...

Stepwise degradation of keratan sulfate. The deficiency diseases corresponding to the numbered reactions are 1 = MPS IV A, Morquio syndrome type A 2 = MPS IVB, Morquio syndrome type B 3 = MPS III D, Sanfilippo s syndrome type D 4 = Sandhoff s disease and 5 = Tay-Sachs and Sandhoff s disease. The alternate pathway releases intact N-acetylglucosamine-6-sulfate, a departure from the usual stepwise cleavage of sulfate and sugar residues. [Reproduced with permission from E.F. Neufeld and J.
