[Intraoperative leg length measurement in total hip endoprosthesis]

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering

Context:

• Total hip arthroplasty (THA) can lead to leg length discrepancies.
• Accurate leg length equalization is vital for patient function and satisfaction.

Purpose:

• To present novel measuring instruments for direct intraoperative leg length assessment during THA.
• To demonstrate the utility of these instruments in achieving precise limb length restoration.

Summary:

• The study introduces specific instruments for direct intraoperative measurement to ensure equal leg length after total hip arthroplasty.
• These tools, applicable to posterior approaches and other hip surgeries, also aid in acetabular component anteversion and inclination assessment.
• Intraoperative use demonstrated high accuracy, significantly improving outcomes compared to radiographic measurements from previous series.

Impact:

• Facilitates improved surgical precision in total hip arthroplasty.
• Reduces the incidence of leg length discrepancies, enhancing patient mobility and comfort.
• Offers a versatile tool for orthopedic surgeons, aiding in multiple aspects of hip reconstruction.
