LT: lesser trochanter, post: posterior, TAD: tip-apex distance, LLD: limb length discrepancy, TA: traffic accident, DHS: dynamic hip screw, CCS: cannulated cancellous screw, G: general anesthesia, TSP: trochanter stabilizing plate.

^*Whether the head-neck fragment contained more than 1/2 of the lesser trochanter length. ^†Whether posterior sagging of distal shaft fragment relative to the head-neck fragment was present in the preoperative hip translateral view.
