Femoral neck fractures treated with cannulated screws: can …
Internal fixation of femoral neck fracture with three screws is a minimally invasive surgical procedure: following an external reduction operation, three cannulated screws are inserted with a percutaneous technique. Risks connected to surgery are reduced as compared to hip arthroplasty, since bleeding is minimalized, and the procedure is shorter.
A recent update on the fixation techniques for femoral neck fractures …
2024年5月27日 · Osteosynthesis techniques, including dynamic hip screw (DHS), multiple cannulated screws (MCS), and the femoral neck system (FNS), aim to achieve stable fixation and facilitate fracture healing. Factors influencing the choice of osteosynthesis include fracture displacement, bone quality, patient age, and the presence of posterior tilt.
Dynamic hip screws versus cannulated screws for femoral neck fractures …
Dynamic hip screw (DHS) and cannulated screws (CS) are widely used for femoral neck fractures. However, there is no definite result as to which surgical method bring less complications. We performed this study to compare the complication (mortality, non-union, avascular necrosis (AVN), and revision) of DHS and CS for the treatment of femoral ...
Internal fixation using fully threaded cannulated compression screws …
Short versus long thread cannulated cancellous screws for intracapsular hip fractures: a randomised trial of 432 patients. ... Moosavi M, Golbakhsh MR, Savadkoohi D, Zehtab MJ. A comparative study between multiple cannulated screws and dynamic hip screw for fixation of femoral neck fracture in adults. Int Orthop. 2015;39:2069–2071. doi: 10. ...
The 6.5/8.0 mm Cannulated Screw System is part of a series of cannulated screws ranging from 4.0 to 8.0 mm. Matching a combination of screw options with necessary instrumentation, the
The ratio between the screw distance and femoral neck width on …
3 天之前 · The results showed that a greater incidence of “displaced fracture” and a lower ratio of the screw distance to the femoral width were important risk factors for femoral head necrosis in cannulated screw-fixed patients (Table 2 and Table 3). Finally, we performed receiver operating characteristic (ROC) curve analyses to assess the ability of ...
Cannulated screws versus dynamic hip screw versus …
2023年8月26日 · Our aim was to determine the best operative procedure in human participants with a displaced or non-displaced femoral neck fracture comparing cannulated screw (CS) fixation, dynamic hip screw (DHS) fixation, hemiarthroplasty (HA), and total hip arthroplasty (THA) in terms of surgical and functional outcomes, reoperation and postoperative complic...
Accurate Placement of Cannulated Screws in Femoral Neck Fractures …
2021年10月19日 · Cannulated screws have been widely accepted by surgeons for clinical use because their application causes little additional injury, involves a simple operation, and has little influence on the blood supply of the femoral head. Multiple cannulated screws should be distributed in the femoral neck in a parallel fashion.
