SURGICAL DISEASES, TRAUMATOLOGY, ORTHOPEDICS, UROLOGY : HYGROMA (НУGROMA) - etiology, pathogenesis, symptoms and course of, recognition, prediction and prevention
Etiology. Trauma - caused bleeding in the mucous bag, more often - repeated mechanical trauma bags with long-term pressure on the same spot.
The pathogenesis. The most frequent localization of hygroma prepatellar, elbow bags, under the deltoid muscle, the area of greater trochanter of the thigh, popliteal region, under filloval tendon, Palmar and dorsal sides of the hand. In addition to chronic serous synovitis, there is a thickening of the bag, villous its expansion, the formation material of the strands and bars, pockets, bays. Often, especially in tuberculous lesion in the bag hygroma vacant rice cells. In some cases, mainly in the bags field shoulder joint, is the deposition of lime (bursitis calcarea).
Symptoms. Tumor supple, rounded, smooth, painless or a little painful when pressure in the characteristic location of the bag. In a tight filling of a solid tumor, often makes the fluctuation. Felt seal wall, sometimes rice cells. The base of the tumor is closely linked with the smash of deep tissues (bone), leather mobile, is going to fold over the tumor. For bursitis calcarea is characterized by the presence of pain during movement, limited mobility in the joint and the pressure sensitivity of a particular site.
The disease is chronic, sometimes acute exacerbations (stress, pain, and increase effusion) and improvements with reduction of the tumor.
Recognition in a typical localization is not difficult; the great difficulty is sometimes etiological diagnosis. Elucidation of tubercular etiology is facilitated by the x-ray detecting primary localization of tuberculosis in the bones. The diagnosis of bursitis calcarea is made on the basis of radiographs, which are determined by the sharp shadows calcified bags.
Repeated puncture results usually only in subacute course, in the other cases shown operative excision of the bag. When bursitis calcarea - radiotherapy.
