- Abstract
One of the most frequently used cementless hip prostheses is the AML (Anatomic Medullary Locking) device, a prosthesis with a predominantly diaphyseal fixation, porous coating, straight metaphysis and a cylindrical modular stem, which has proven useful in studies with a follow-up as long as 20 years. We studied 74 hips in 66 patients at the Central Military Hospital, with a minimum follow-up of 3.5 years and a maximum of 9 years, mean follow-up was 6.8 years. Mean age of males was 57.05 years and 68.06 years for females. Of the patients studied, only 2 needed a revision; one case due to deep infection and another one due to loosening secondary to misplacement of the femoral stem. The remaining complications were few; all of them were minor, did not warrant revision surgery and did not lead to patient disability. As reported in the world literature, main complications include moderate thigh pain, stress shielding, leg length discrepancy, and dislocation of the prosthesis. We concluded that the AML cementless prosthesis represents an excellent option for hip replacement, whether due to arthrosis or any other reason, provided the patient has good bone quality and proper preoperative planning is done. Results are comparable to those published in the world literature.
