A comparison of intramedullary cannulated screws versus miniplates for fixation of unstable metacarpal diaphyseal fractures

Journal of Hand Surgery (European Volume), 2021
We carried out a prospective randomized study to compare the clinical and radiological results of metacarpal diaphyseal fractures treated with retrograde intramedullary headless cannulated screws (IHCS) and plates.

Technique for Removal of Cannulated Screws

Journal of Orthopaedic Trauma, 2005
Cannulated screws can become incarcerated or stripped during the process of initial open-reduction internal fixation or at the time of hardware removal. In addition, many different sizes and brands of cannulated screws exist, and the appropriate size or type of screwdriver may not be available.

Impact of Bone Graft on Fusion Rates in Primary Open Ankle Arthrodesis Fixated With Cannulated Screws: A Systematic Review.

Journal of Foot and Ankle Surgery, 2021
There is currently no consensus on the importance of bone graft use in ankle arthrodesis. Despite this, bone graft is widely used. We aimed to summarize the available literature on primary open ankle arthrodesis fixated with cannulated screws in order to

Cannulated screws for odontoid screw fixation and atlantoaxial transarticular screw fixation

Journal of Neurosurgery, 1995
✓ Cannulated screw systems use thin Kirschner wires (K-wires) that have been drilled into the bone to direct screw trajectories accurately into small bone fragments. Use of the K-wires avoids overdrilling the pilot holes and allows fixation of adjacent bone fragments during screw insertion. Hollow tools and hollow screws are inserted into the bone over

Extraction Strength of Cannulated Cancellous Bone Screws

Journal of Orthopaedic Trauma, 1993
The purpose of this study was to determine whether the alterations in the relative dimensions of thread and core diameter that accompany cannulation of cancellous bone screws affect their holding strength. The screws were inserted in bovine femoral cancellous bone and mounted in the load train of a materials testing system.

Effect of the Number, Size, and Location of Cannulated Screws on the Incidence of Avascular Necrosis of the Femoral Head in Pediatric Femoral Neck Fractures: A Review of 153 Cases

Journal of pediatric orthopedics, 2021
Background: The correlation between the number, size, and location of cannulated screws and the incidence of avascular necrosis (AVN) in children with femoral neck fractures treated surgically is uncertain.

Femoral Neck System Compared with 3 Cannulated Screws in the Treatment of Femoral Neck Fracture in Patients Aged 60 and Older

Journal of Bone and Joint Surgery. American volume
Background: While the Femoral Neck System (FNS) is increasingly utilized for the fixation of femoral neck fractures in elderly patients, studies comparing the device to the historical standard (that is, multiple cannulated screws) are lacking.

Cervical Pedicle Screws: Conventional Versus Computer-Assisted Placement of Cannulated Screws

Spine, 2005
Prospective clinical study with postoperative radiologic control of pedicle screw placement in the cervical spine.To evaluate whether cervical pedicle screws can be placed safely in a conventional technique when using cannulated screws and separate stab incisions. Also, to evaluate if accuracy and safety of pedicle screw placement can be improved using
