It can also be used to determine level and plumb using a level vial. How to use a combination square to draw a 45-degree angle:
WebThe measurement of the head-shaft angle (HSA, Fig. 1) was popularised by Southwick [1] to measure the degree of slip in slipped upper femoral epiphysis. Foroohar et al. [2] evaluated the relationship between the femoral shaft and head in children with cerebral palsy (CP) and compared the HSA in children with CP with the HSA in WebThe alpha angle was first described by Notzli et al. in 2002 as an objective tool to evaluate the femoral head–neck junction. Angles greater than 55° were thought to be associated …
