Enhancing the Accuracy of Pedicle Screw Placement Using 3D-Printed Screw-Guiding Techniques in the Lumbosacral Region for Small Breed Dogs: A Cadaveric Study

Animals
A 3D-printed guide is an effective method for accurately placing pedicle screws in dog vertebrae. While a conventional drill guide allows precise pilot hole formation, it can lead to potential screw wobbling during insertion.

Fixation principles in metaphyseal bone—a patent based review [PDF]

, 2018
Osteoporotic changes start in cancellous bone due to the underlying pathophysiology. Consequently, the metaphyses are at a higher risk of "osteoporotic” fracture than the diaphysis. Furthermore, implant purchase to fix these fractures is also affected by

Outcomes of Headed and Headless Cannulated Screws Fixation in Nondisplaced Femoral Neck Fracture

Geriatric Orthopaedic Surgery & Rehabilitation
Background The incidence of femoral neck fracture is increasing as society ages. Different types of cannulated screws can be used for internal fixation of femoral neck fractures, but no screw selection protocol has been determined to reduce the risk of ...

Is diamond-shaped screw fixation a viable alternative for Pauwels type III fractures? A biomechanical comparison of three constructs

BMC Musculoskeletal Disorders
Background Pauwels type III femoral neck fractures are characterized by steep, vertically oriented fracture lines and are biomechanically unstable due to high shear and varus forces. While sliding hip screws (SHS) and cannulated screw (CS) constructs are
