CT evaluation of torsional malalignment after intertrochanteric fracture fixation

Abstract

Level III. Prospective diagnostic study with no control group.

Torsional malalignment, how much significant in the trochanteric fractures?

“…Torsional malalignment in subtrochanteric fractures in the proximal area has been reported, but few studies on torsional malalignment in trochanteric fracture have been reported. Most recently, Ramanoudjame et al reported torsional malalignment cases using CT images of inter-trochanteric fracture, 15-degrees or more torsional malalignment occurred in about 40% of the subjects after surgery, with anteversion being the most common [2]. However, few studies on the clinical results of these malalignments have been reported.…”

“…Accordingly, few studies on such evaluation have been reported. In a recent study on torsion in trochanteric fracture, the ratio of torsional malalignment was about 40% based on the postoperative CT images, and the torsional malalignment was mainly a type of increased anteversion [2]. The femoral version must be given attention considering its effect on femoral loading Objectives: The rotational alignment is definitely important in the long bones such as tibias and femurs.…”

Optimizing intraoperative imaging during proximal femoral fracture fixation – a performance improvement program for surgeons

“…In closed nailing for pertrochanteric fracture fixation there is a considerable incidence of malreduction with 40% of more than 15 internal rotation [5]. Malpositioning of implants due to residual malreduction leads to a higher number of mechanical failures [6][7][8].…”

CT Evaluation of Rotational Malalignment after Intertrochanteric Fracture Fixation

“…The frontal images do not hold true for rotational malalignment. The objective of this prospective study was the CT evaluation of the quality of hip reduction in the horizontal plane (4) . After procedure, the same day of the operation, a CT was done with measurement of anteversion in neck of both femurs.…”
