ABSTRACT
The purpose of this paper is to present preliminary findings of an ongoing prospective study of the effectiveness of total digital implants. Forty hinged implants and 22 nonhinged implants have been evaluated to compare the two implants and establish preoperative criteria for their use. Our findings indicate better results for toe purchase and stability with the nonhinged implant and marginally better joint range of movement with the hinged implant. Preoperative dorsal contracture at the metatarsophalangeal joint leads to the most consistent postoperative complications.

Pregnant mice were treated with antiserum to LH or bromocriptine to inhibit the activity of LH and prolactin, respectively. Luteal function was monitored by the radioimmunoassay of plasma progesterone. Bromocriptine treatment on Days 2 or 5 of pregnancy produced a rapid decrease in progesterone secretion, but had no effect on luteal function when given on Days 6, 7 or 8 of gestation. Treatment with LH antiserum before implantation did not inhibit progesterone secretion, but luteal function was severely impaired when the antiserum was given on Days 5--9 of pregnancy. These results demonstrate the dynamic nature of luteal dependency on prolactin and LH, and indicate that LH is an essential component of the luetotrophic complex of the mouse.
