Radioactive synoviorthesis in hemophilic hemarthrosis: materials, techniques, and dangers.

Radioactive synoviorthesis with 198Au, 90Y, 186Re, and 31P would seem to be the treatment of choice for recurrent hemarthroses in hemophilia. The clinical results, obtained by different centers, show a definite diminution of hemarthroses in 88% of cases. The advantages of radioactive synoviorthesis compared with surgical synovectomy are: better results, the requirement of substantially reduced antihemophilic factor, the possibility of performing the procedure on multiple cases concurrently on an ambulatory basis, no interference with articular range of movement, and the low cost of the procedure.

Stability following fracture-dislocations of the cervical spine.

After having dealt with over 150 cases of fracture-dislocations of the cervical spine, the authors conclude that conservative orthopaedic treatment leads to the best results. The lesions are classified in upper and lower cervical spine. The latter has been divided into two subgroups according to the presence or abscense of neurological involvement.
