[Osteal scintigraphy in the evaluation of the course of reparative processes after surgical treatment for tuberculous and nonspecific arthritis, by using constrained bone grafting].

Osteal scintigraphy was used to study the course of reparative processes after surgical treatment in 106 patients with large joint lesions, including 76 patients with tuberculous arthritis and their sequels and 30 with nonspecific and dystrophicones before and 2-3 weeks after operations (those with and without articular tissue revascularization (n = 43 and n = 63); mobilizing (n = 64) and stabilizing (n = 42) operations), of them 22 being performed in late periods (1-3 years (n = 16)). It was established that after mobilizing operations with revascularization, the early postoperative period was marked by a significant increase in radionuclide accumulation (by 1.52 times) and after those without revascularization, there was a less significant rise (by 1.34 times); following stabilizing operations with revascularization, hyperfixation was similar before and after surgery whereas following those without revascularization it significantly reduced (by 1.53% in 70% of patients). The late postoperative period was characterized by reduced hyperfixation, which was more evident after mobilizing operations with revascularization. Osteal scintigraphy quantifies the course of reparative processes and determines the efficiency of different operations.
