Implant failure of the gamma nail

Injury, 1999
The gamma nail is a temporary implant characterised by a limited life expectancy under continuous dynamic stress. We reviewed a series of 839 patients with gamma nail stabilisation and found two fatigue fractures (0.2%) at the aperture of the distal locking holes. This complication has not been described in the literature.

Antiphospholipid Antibodies in Implantation Failures*

American Journal of Reproductive Immunology, 2003
PROBLEM:  The amino phospholipids (PL), phosphatidylserine (PS) and phosphatidylethanolamine (PE) are distributed asymmetrically in the plasma membranes of eucaryotic cells. This arrangement involves active transport of PS and PE from the outer to inner membrane leaflet by an aminophospholipid translocase (flipase).

Resolving recurrent implantation failure

Reproductive BioMedicine Online
Recurrent implantation failure (RIF) continues to represent a difficult clinical challenge. Discussion of its definition continues and the evidence base to support optimal management is weak. Recent studies showing excellent cumulative outcomes following serial transfer have challenged the notion of RIF as anything other than a rare biological ...
