Calcific Tendinopathy of the Rotator Cuff: Pathogenesis, Diagnosis, and Management.

Calcific tendinopathy, or calcifying tendinitis, is a disease characterized by multifocal, cell-mediated calcification of living tissue. After spontaneous disappearance of the calcific deposits or, less frequently, surgical removal, the tendon reconstitutes itself. Attention to the clinical presentation and the radiologic, morphologic, and gross characteristics of the calcium deposit will facilitate differentiation between the formative phase and the resorptive phase, which is of paramount importance in the management of this disease. Should conservative treatment fail, surgical removal may be indicated during the formative phase, but only under exceptional circumstances during the resorptive phase. Aspiration and lavage of the deposit should be performed only during the latter phase.

Rotator cuff tears of the hip.

Pain over the lateral aspect of the hip commonly is attributed to trochanteric bursitis. Typical findings include local tenderness and weakness of hip abduction. When conservative measures fail to relieve symptoms, surgical release of the iliotibial band over the greater trochanter has been recommended. In the management of seven such patients, an unusual finding was encountered: partial tear of the gluteus medius tendon at its attachment to the greater trochanter. Each patient presented with increasing hip pain of duration of months to years. There were no diagnostic findings on physical examination. Magnetic resonance imaging showed an abnormal signal within the tendon of gluteus medius and fluid within the trochanteric bursa. The disrupted tendons were reattached to bone with heavy nonabsorbable suture. At a median followup of 45 months (range, 21-60 months), all patients were free of pain.

[Rupture of the rotator cuff].

Spontaneous or traumatic ruptures almost always occur in a cuff that has degenerated due to overuse. Despite the lack of absolute anatomico-clinical correlation, two clinical types can be described: a conflictual, often hyperalgesic shoulder with its painful arch corresponding to a small anterosuperior rupture, or a pseudo-paralytic shoulder betraying a major posterosuperior rupture. Standard radiography with Leclercq's manoeuvre is performed primarily to find out whether the cuff is continent or incontinent. Modern medical imaging (ultrasonography or MRI) adds precision to the lesions when surgery is contemplated. When medical treatment has failed, partial ruptures are treated by arthrolysis; ruptures of the superficial and deep layers of the cuff without calcification benefit from endoscopy; ruptures involving tendons or associated with calcifications are treated by surgery. Small and medium ruptures with a continent cuff require endoscopic or surgical anterior decompression combined, in cases where the intra-articular long head of the biceps is exposed, with repair, usually by suture. Extensive ruptures with an incontinent cuff are treated by muscle transfer alone of combined with arthroplasty, or by semi-constrained total prosthesis when arthrosis of the humeral joint is present.

[Current and known aspects of the arterial supply of the rotator cuff].

The basic arterial supply of the shoulder is well known, some details for example the supply of the m. supraspinatus are not studied yet. Preparation of shoulder-specimens after injection of silicone-caoutchouc are done to examine the vascular system. The arterial supply of the shoulder is described as a system of four rings. The results are discussed in combination with the literature.
