Measuring tttg
WebPurpose: Many studies have confirmed the significance of tibial tuberosity‑trochlear groove (TTTG) distance measurement for the preoperative assessment of tibial tubercle osteotomy and refixation of the patients that need surgery. TTTG distance is being used as threshold value for surgery decision. The purpose is to determine the TTTG values http://xrayhead.com/measure/show_measurement.php?i=2

We utilized a dynamic kinematic computed tomography scanning method to measure TTTG distances at various flexion angles in patients with recurrent patellar instability, and correlated this to …
WebJan 24, 2024 · This measurement is obtained from CT scanning and is abnormal in 56–93% of cases with patellar instability [3] and nearly all cases with trochlear dysplasia [1], [2]. An excessive TTTG can be used as the indication for a distal realignment procedure such as medialising the tibial tubercle [2]. Webshown to be superior for the measurement of the TT-TG distance by eliminating projectional errors inherent to radiography [3]. More recent-ly, MRI has been validated as a reliable means of measuring the TT-TG distance using axial MR images and a digital workstation [4–6]. Reported normative ranges for the TT-TG distance have varied.
WebTibial tuberosity-trochlear groove distance (TTTG) is very important in the assessment of patellofemoral joint instability. The purpose of this study was to report the normal value of TTTG in males and females in different age groups and to assess the reliability of MRI in measuring TTTG.
