Fig. 1

A photo shows 3.5 locking head screws with stripped hexagonal recess.

Fig. 2

Conical extraction screws and drills for the removal of the stripped head16) (Oh et al, with permission).

Fig. 3

Two of the three proximal locking screws seem to be placed through the posterior cortex itself because the plate is placed too posteriorly to the femoral shaft.

Fig. 4

Subtle malposition of the plate can result in failure of the locking head screw fixation.

(A) Unusual resistance during the drilling prompted us to check this image, finding the drill bit was passing through the anterior cortex itself.

(B) True lateral image shows just a little bit of plate malposition.

(C) The most distal hole has to be filled with a conventional screw due to the plate malposition.
