Treatment of Femoral Neck Fractures with a Sliding Compression Screw and Two Knowles Pins

Comparative results of percutaneous cannulated screws, dynamic compression type plate and screw for the treatment of femoral neck fractures

“…However, there are studies that report 8-16% AVN in similar type of fractures. [5,30,[39][40][41] Barnes et al [8] reported an AVN rate of 22% and Ort et al [42] reported an AVN rate of 24% in femoral neck fractures treated by DHS. We found higher rates (30% in our Group II patients with DHS), which may have been caused by selection bias.…”

“…Unlike our results, Shih and Wang [44] reported a union time of six months in 121 patients with a mean age of 36.8. Rodriquez [45] reported a 95% union rate after fixation with cannulated screws, and Ort et al [42] reported a 90.4% union rate after fixation of femoral neck fractures with DHS. Similarly, we found union rates of 97% and 91% in Groups I and II, respectively.…”

Fixation of displaced femoral neck fractures: A comparison between sliding screw plate and four cancellous bone screws

“…The stability of the weight-bearing unit is increased when compression is applied across the fracture line (Kaessman et al 1972). This can be obtained with the SSP fixation devices by means of a compressing screw (Charnley 1957, Hargadon & Pearson 1963, Svenningsen et al 1984, Ort & LaMont 1984, Skinner & Powles 1986). Because of the risk of breaking the trabecular bone thread by tightening the compressing screw, it was used with caution in our patients and was not applied if the bone structure was thought to be weak.…”

“…supplemented with an extra screw or pin (Zickel 1985, Svenningsen et al 1984, Ort & LaMont 1984. In the other treatment group, we applied 4 ASIF cancellous bone screws as employed by H$gh et al (1982).…”

Dynamic Hip Screw in Fractures of the Proximal Femur

“…While the number of displaced femoral neck fractures was markedly high in other studies (Brown et al 1964. 12 Ort et al 1984 andSvenningsen et al 1984). This series had similar observations as mentioned above.…”
