Minimally Invasive Hip Replacement

Minimally Invasive (MIS) Total Hip Replacement

Total hip replacement has been refined over the last decade. It can be done safely, with shorter hospitalizations, and in some cases as an out patient. Minimally invasive hip replacement results in less discomfort and fewer complications–as long as careful attention to detail is combined with state-of-the-art techniques are utilized. One of the more recent refinements of total hip replacement involves an anterior approach to the hip.

Historical Perspective

The surgical approach must allow adequate visualization of important bony landmarks and critical structures such as nerves and vessels. Implant position affects stability, long-term performance, and leg lengths. It is of utmost importance that the approach allows for adequate visualization. In many centers, a 10 – 14 inch incision is used routinely.

Minimally Invasive Hip Replacement

Not all patients need the standard incision. Recent enhancements in surgical technique have allowed more limited surgical approaches in certain patients. Down-sized instruments, selected implants, and minor modifications of the surgical dissection allow hip replacement to be done through a smaller incision, with much less surgical dissection, and with less trauma to the muscles and tendons around the hip. Minimally invasive approaches to the hip can be done through an anterior or a posterior approach.

The benefits of a MIS approach are

  • Better cosmetics
  • Less postoperative pain
  • Less blood loss
  • Earlier rehabilitation
  • Fewer wound complications
  • Out patient hip replacement in some selected patients

It is important, however, to understand that small incisions for hip replacement are a recent development. Precise placement of hip components remains the primary goal of the surgery, and this goal should not be compromised for a smaller incision. Patient factors such as weight, stiff hips, previous hip surgery, and hip deformity can require the standard sized incision.
