Anterior hip replacement

The anterior approach to total hip replacement (AMIS) has emerged recently as a viable alternative to
the more popular posterior approach. Although the anterior approach is known from the past, new
technologies and instrumentations made the operation possible by using smaller incisions (6-8 cm)
through the front of the hip.
Called the mini anterior hip replacement, this procedure involves the surgeon making a four-inch
incision through the front of the leg, rather than the back (the entry point for the more conventional
posterior hip replacement surgery). Frontal entry makes it possible to reach the joint
ATRAUMATICALLY, by separating rather than cutting and then reattaching muscles. This result in:
1. Less blood loss
2. Less postoperative pain
3. Short hospitalization stay (1-2 days)
4. Full weight mobilization just 3 to 4 hours after the procedure
5. Reduced risk for DVT and PE
6. Faster rehabilitation
7. Less risk for hip dislocation
Furthermore, due to the patient’s supine position, the surgeon is able to check the position of implants
with the use of fluoroscopy, and the leg length as well.
Postoperatively, patient is mobilized with walking aids such as crutches or sticks. The patient can stop
using this once he / she is feeling confident to walk independently, usually within 1 to 2 weeks.
Choice of the prosthesis design is extremely important. I generally choose the design in discussion with
the patient. I would choose a prosthesis that has established long term results as published in
international medical journals. I would insist on using one of these tried and tested implants.
