Advances in surgical technique for total hip replacement: without and with osteotomy of the greater trochanter
Insights
Osteotomy of the greater trochanter is often unnecessary in total hip replacement, simplifying the procedure. Complex cases may still benefit from this surgical step for better outcomes.
Area of Science:
- Orthopedic Surgery
- Arthroplasty Research
Background:
- The necessity of greater trochanter osteotomy in total hip replacement (THR) remains a subject of debate.
- Surgical techniques evolve, impacting the approach to THR and its associated osteotomies.
Purpose of the Study:
- To evaluate the necessity of greater trochanter osteotomy in total hip replacement.
- To discuss the indications and contraindications for trochanteric osteotomy in THR.
Main Methods:
- Review of current surgical techniques in total hip replacement.
- Analysis of cases with and without greater trochanter osteotomy.
- Consideration of complications associated with trochanteric osteotomy and reattachment.
Main Results:
- Most straightforward total hip replacements can be performed without osteotomy of the greater trochanter.
- Osteotomy is beneficial in complex cases, revision surgeries, severe deformities, or when using long femoral stems.
- Techniques exist to perform THR with wide exposure without osteotomy, preserving the abductor muscle group.
Conclusions:
- Greater trochanter osteotomy is not routinely required for uncomplicated total hip replacement.
- Careful patient selection and surgical planning are crucial for determining the need for osteotomy.
- Advances in cementing and component positioning enhance overall arthroplasty outcomes.
Abstract:
Advances in the surgical technique for total hip replacement demonstrate that in most straightforward cases, osteotomy of the greater trochanter is unnecessary. This point of view requires some consideration of the present controversy about the need for osteotomy of the greater trochanter. If the limb is to be shortened or if a graft is to be added to the ilium, the trochanter must be removed. In complex cases necessitating revision operations or correction of severe deformities, or in hips requiring long stem components, osteotomy of the trochanter can be a distinct asset. There are pitfalls and complications of the techniques, both with and without trochanteric osteotomy, as well as with methods of reattachment of the trochanter. In general, total hip replacement can be performed with wide exposure of the socket without osteotomy of the trochanter, and can be performed without damage to the abductor muscle group. New cementing procedures and more accurate positioning of the femoral component have significantly improved the end results of total hip arthroplasty.
