[Initial results following implantation of silastic wrist joint prostheses in patients with chronic polyarthritis with additional use of titanium grommets].
Implantation of titanium grommets should protect the flexible implant from the sharp bone edges and avoid fracture of the implant. In case of bone cysts and thin corticalis they should provide further support against countersinking. Swanson et al. (1982) reported bone remodeling phenomena around the grommets and the implant. Eight patients suffering rheumatoid arthritis have been reviewed at an average of 18 months (12 to 24 months) following operation with the flexible implant and additional grommets. The following results were observed: 1. No fractured implants were noted in any patient. 2. In two cases resorption was noted around the proximal grommet. 3. In no case was new bone formation noted. 4. In one case the flexible implant and the grommets became countersunk into bone.
