Minimally invasive anterior hip replacement

Main features of the technique before surgery :

  • doc1-incisions-compareesMost arthritis and necrosis of the hip joint that rightly require an implant (see Hip replacement chapter) can benefit from this new technique.
  • A hip replacement performed conventionally requires more often than not a muscle section and leaves a scar of about 20 cm (about 8 inches).
  • An implant placed by minimally invasive anterior procedure requires no muscular section and the scar is about 7 or 8 cm (about 3 inches) long. This can explain why post-operative sequels are simpler and rehabilitation is often faster.

During surgery :

  • doc3-interventionThe procedure consists in placing the implant through a very tight space by gently finding a way between two muscles with specially designed retractors.
  • All the implant models for total hip replacement, even the newest, can be placed by using this technique.
  • The procedure duration is about 1h30 to 1h45
  • A radiography during the procedure may allow if needed, to monitor the good positioning of the implants into the femur and the hip bone.

Minimally invasive anterior hip replacement :

After surgery :


  • The absence of muscular sections allows to expect fewer post-operative sequels.
  • This technique allows to reduce :
    – Blood loss and thus transfusions
    – Pain and thus taking medicines
    – Risks of prosthesis dislocation
    – Risks of phlebitis after faster recovery of walking motion
  • The post-operative care duration at the clinic is often reduced; returning home is possible sometimes after 6 or 7 days, without compulsory stay in a rehabilitation centre.
  • Scar 3 months after surger
