Treatment of 34 cases of femoral condyle and intercondylar fracture with dynamic iliac screw
The location and sensitivity determine the amount of exposure and the time of exposure. The problems often encountered during the treatment are: (1) efficacy problems: the efficacy varies greatly depending on the type of hemangioma, the size of the tumor, and the individual. Strawberry hemangioma and cavernous hemangioma are the best, and the smaller tumors are cured after 1~2 courses of treatment. The effect of port wine stains is poor, the cure rate is only 30.2% for a course of treatment, 54.9% of patients need 2 to 3 courses to heal, 6.7% of patients need 4 courses to improve or heal, but basically all patients have effects . The size of the tumor is inversely proportional to the effect. The larger the tumor, the longer the treatment time. The sensitivity of the body to radiation is inversely proportional to age. The younger the age, the more sensitive the radiation is, the better the treatment result is. 131. (2) The tumor is large and thick: because the P-ray has a shorter range, more than 5mm is basically invalid. Therefore, the thickness of the tumor is greater than 5mm, and the combination therapy should be selected, that is, the local injection of colloidal 32P, prednisone or pingyangmycin and other drugs should be applied. After the tumor is reduced, the application can be applied to obtain a good effect. (3) The hemangioma of the face and head is rich in blood vessels at this site, and the treatment time often takes 3 to 4 courses. (4) The hemangioma of the perineum and mucous membranes of the lips is easily broken, and sometimes the mucosal ulceration occurs when 600 to 800 rad is given. For the hemangioma in these areas, the treatment principle is: relatively reduce the dose, increase the number of treatments, prevent the occurrence of ulceration, until the cure. (5) For the problem of hair loss in the lesion area, we observed 275 cases and found only temporary hair loss, and no intractable irreversible hair removal. (6) If wet dermatitis occurs during the treatment, the treatment should be stopped immediately, and the paralyzed patients should maintain local hygiene and give symptomatic treatment. (7) For patients with large-area hemangioma treated with multiple courses of treatment, attention should be paid to observe the elasticity of the affected part of the skin. Decide whether to treat the next course of treatment. The effect of radionuclide dressing on the treatment of cutaneous hemangioma depends on the amount of radiation absorbed by the radiation and the time of the treatment interval. Because of individual differences, the sensitivity to radiation is also different. The factors such as lesion location, lesion size, disease type, length of onset, and treatment by other methods can directly affect the treatment effect. Therefore, in the specific treatment, the irradiation dose and the treatment interval must be adjusted at any time according to different conditions, in order to achieve the desired therapeutic effect and avoid side effects.
