Abstract

Abstract:

BACKGROUND: Accurate and reliable measurement of full lower extremity alignment is very important for preoperative planning and postoperative assessment in corrective knee surgery such as high tibial osteotomies and arthroplasties.
OBJECTIVE: To discuss the effectiveness of peripheral stepping angiography disposable exposure imaging method for full lower extremity alignment measurement.
METHODS: The full lower extremity alignment images of 13 patients suffered from knee osteoarthritis and varus were obtained by the peripheral stepping angiography. Two ways of images were taken, standing and supine position. Orthopedic surgeons measured the angle of limb alignment using a protractor on hard-copy X-ray radiographs, while radiologists measured the angle of limb alignment on the computer screen. Differences and the correlation coefficient research between the data were performed.
RESULTS AND CONCLUSION: The peripheral stepping angiography disposable exposure imaging method for full lower extremity alignment measurement had high accuracy and reliability, and there was good correlation between manual measurement and computer-assisted digital image measurement (r=0.638-0.975).
