    Revision total hip replacement can often be performed without trochanteric osteotomy, reducing complications and improving rehabilitation. This approach eliminates risks like nonunion and abductor weakness associated with the traditional osteotomy method.

    Area of Science:

    • Orthopedic Surgery
    • Arthroplasty
    • Reconstructive Surgery

    Background:

    • Traditional revision total hip replacement (THR) frequently involves trochanteric osteotomy for component removal and reinsertion.
    • Trochanteric osteotomy in revision THR is associated with a significant rate of complications, including nonunion, delayed healing, and abductor weakness.
    • Minimally invasive techniques are increasingly explored to improve outcomes in complex orthopedic procedures.

    Purpose of the Study:

    • To evaluate the efficacy and safety of performing revision total hip replacement without trochanteric osteotomy.
    • To compare the outcomes of revision THR with and without trochanteric osteotomy, focusing on complications and functional recovery.
    • To identify specific indications and contraindications for a trochanter-sparing approach in revision hip arthroplasty.

    Main Methods:

    • A retrospective review of 63 revision THR procedures in 52 patients over a 2- to 7-year follow-up period.
    • Patients were divided into two groups: 21 undergoing trochanteric osteotomy and 44 utilizing a trochanter-sparing technique.
    • Data collected included operative details, intraoperative complications, postoperative outcomes (e.g., blood loss, abductor strength, ambulation, pain), and specific trochanteric complications.

    Main Results:

    • The trochanter-sparing group demonstrated a 21% decrease in blood loss, 14% less persistent abductor weakness, and a 14% reduction in subluxation/dislocation.
    • Operating time decreased by 30%, and intraoperative femoral perforation was reduced by 50% in the non-osteotomized group.
    • The osteotomized group experienced six cases of fibrous union and two instances of broken wire removal for trochanteric bursitis.

    Conclusions:

    • Revision total hip replacement can be successfully performed without trochanteric osteotomy in carefully selected cases.
    • Avoiding trochanteric osteotomy effectively eliminates postoperative complications such as nonunion, broken wires, bursitis, and abductor weakness.
    • The trochanter-sparing technique offers advantages in reduced blood loss, improved functional recovery, and decreased operative time compared to traditional osteotomy.
