Summary
This study introduces a novel minimal access hip replacement technique using a small incision without navigation or X-rays. The technique demonstrated reduced pain and improved function in patients, offering a less invasive option for total hip replacement.
Area of Science:
- Orthopedic Surgery
- Minimally Invasive Procedures
Background:
- Minimal invasive surgical techniques are increasingly adopted for various orthopedic procedures.
- Traditional hip replacement often involves larger incisions and may require navigation or X-rays.
Purpose of the Study:
- To report the first instrumented technique for total hip replacement using a minimal 5-cm incision.
- To evaluate the feasibility and outcomes of this novel technique without navigation or X-rays.
Main Methods:
- The study utilized a universal C.F.P stem (LINK) with specialized jigs, a reamer, and spacers for acetabular cup orientation.
- A case series of seven patients underwent this new hip replacement technique, termed the NILNAV Hip System.
Main Results:
- The procedure was successfully performed on all seven patients.
- Patients experienced reduced postoperative pain and stiffness.
- Improved quality of life and functional status were observed, with early discharge on postoperative Days 1 and 2.
Conclusions:
- The minimal access total hip replacement technique was successfully implemented in seven patients.
- This system offers advantages over traditional methods, potentially reducing morbidity and mortality.
- The NILNAV Hip System represents a promising advancement in hip replacement surgery.
