Résumé
The results of stabilization of an intracapsular fracture of the femoral neck with cannulated screws placed in 40 patients between 2002 and 2003 were reviewed. Fourteen patients [35%] had a non-displaced fracture [Garden Stage I or II] and twenty-six [65%] had a displaced fracture [Garden Stage HI or IV]. The mean age of the patients was sixty-two years [range, fifty-four to seventy-five years]. The minimum duration of follow-up was two years [range twenty-four to thirty-six months]. No patient died, had a wound infection or D VT during the stay in the hospital. The hospital stay averaged 3 days [range two to five]. Two patients died within six months after treatment; one of them aged seventy-five years and the other sixty-eight and both were excluded from the study. There was a loss of position or a non-union of the fracture in five patients [12.5%] and healing of the fracture in 35 patients [87.5%]. Nine patients [22.5%] had roentgeno-graphic evidence of osteonecrosis within the first twenty-four months after treatment. Seven of these patients have had a displaced fracture, one had a non-displaced fracture and one was on top of non-union. Osteonecrosis developed in one of the nine patients [11%] who had a Garden Stage-H fracture, in three of the fifteen patients [20%] who had had a Garden Stage-Ill fracture, and in five of the eleven patients [45%] who had had a Garden Stage-IV fracture. The twenty-sevenpatients [67.5%] in whom the fracture healed without complications were found to be functioning well more than eighteen months after the fracture treatment
