Radiographic prediction of early failure in femoral neck fracture

Factors predicting healing complications in femoral neck fractures: 138 patients followed for 2 years

“…In agreement with other studies, the age and the sex of the patient did not correlate to the rate of radiographic healing complications (Nilsson et al 1988, Alberts and Jervaeus 1990, Alho et al 1991, Stromqvist et al 1992.…”

Prediction of fixation failure in femoral neck fractures: Comminution and avascularity studied in 40 patients

“…If either of these factors is present, the risk of failure is increased. Our series is small, which may explain that only 1 of the potentially predictive radiographic signs (Alho et al 1991(Alho et al , 1992) became significant. Hence, the separate role of the circulation disturbance becomes even more obvious.…”

“…The first 2 types of disturbed healing were not necessarily imcompatible with maintained function, but were highly predictive of later failure (Benterud et al 1993). The pretreatment radiographs were analyzed for fracture displacement and comminution of the calcar, which in our previous studies were predictive of early failure (Alho et al 1991(Alho et al , 1992. The later radiographs were also analyzed for late signs of' avascular necrosis (Calandruccio and Anderson 1980).…”

“…The prognostic significance of 9 y m T~ phosphonate scintimetry in femoral neck fractures is well documented (Stromquist et al 1984, Alberts et al 1987, Alberts 1990). Recently, we showed that fracture comminution and displacement also have predictive importance (Alho et al 1991(Alho et al , 1992.…”

High reliability of an algorithm for choice of implants in hip fracture patients

“…The main disagreements in the algorithm were seen among vertical, basocervical and A1.1 trochanteric fractures [3,[9][10][11][12]. Vertical and basocervical fractures must be separated from the common femoral-neck fracture, as they lack varus calcar support for parallel implants and theoretically need a fixed-angle device [1,12,15]. For simplifying the algorithm and potentially raising the agreement even further, treating these fractures with the four-hole sliding hip screw could be considered, despite the longer incision.…”
