Event Description
|
It was reported that during a thr surgery, the doctor prepared acetabulum and took a trial of cup size 50.It was good and fixed well so he took the original reflection shell and it fixed well.He then put a 25mm screw for better fixation, then fixed liner for 32 mm head.Later he prepared the femur fix stem and took trial for the head and reduced the hip joint.When he dislocated the hip to put the original head reflection shell, the liner came out and the screw remained inside the bone (it was later removed).He tried to fix it again but did not succeed and then he took size 54 mm.This caused a delay of thirty minutes to an hour.
