Cannulated (7.0 or 7.3 mm) or noncannulated (6.5 mm) cancellous screws may be used. Cannulated screws are easier to insert but not available in some hospitals. Insertion of cannulated screws is shown in this procedure.

Risk factors for nonunion in patients with intracapsular femoral neck fractures treated with three cannulated screws placed in either a triangle or an inverted triangle configuration.

- Short versus long thread cannulated cancellous screws for intracapsular hip fractures: a randomised trial of 432 patients. - Use of fully threaded cannulated screws decreases femoral neck shortening after fixation of femoral neck fractures.

2017年10月9日 · place a pointed tenaculum or K wire across the fracture for provisional fixation. place 3 or 4 parallel cannulated screws directed from the lateral proximal femur into the head to provide good fixation.

Percutaneous cannulated screw fixation is a well-described and relatively successful technique aimed at addressing femoral neck fractures. The advantages of this technique are limited primarily to its small surgical footprint and ability to preserve native femoral neck bone stock.

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 ...

Femoral neck fractures are still unsolved problems nowadays; sliding hip screw (SHS) and cannulated compression screw (CCS) are the most commonly used devices. We evaluated the clinical outcomes and complications in the treatment of femoral neck ...

Cannulated screws are inserted where the neck of femur has been fractured and where there is a good chance that it will heal if held in place by internal fixation.

2022年4月28日 · Cannulated screws are often used in the fixation of undisplaced or valgus impacted hip fractures. However, due to the potential for avascular necrosis of the femoral head and subsequent femoral head collapse, some surgeons opt for alternative techniques such as a sliding hip screw or arthroplasty.

2023年8月26日 · Background: 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 ...
