Hartigan DE, et al. - Authors identified the radiographic risk factors (RRFs) and radiographic signs of abductor tendon tears. As noted on nearly half of patients with an abductor tear, a wider pelvis, longer abductor moment arm, and longer body weight moment arm and greater trochanteric enthesophyte were seen in the patients with abductor tears. For having an abductor tendon tear, an odds ratio of 20.7 and a positive predictive value of 94% were seen in the presence of an enthesophyte. Enthesophyte presence and teardrop distance were the 2 variables predictive of abductor tendon tear when controlling for all variables, with no other variables significantly increasing or decreasing the likelihood of tear when these 2 variables were considered.
