Comments on bone screws

Techniques in Orthopaedics, 1991
Metal bone screws are a fundamental element of fracture fixation. Screws are described by their thread diameter, thickness of the root of the screw, and pitch. Bone screws are inserted by first making a pilot hole. When screws are used to coapt or lag bone, then a channel has to be drilled the same diameter as the threads. Cannulation of a screw allows

Alendronate Inhibits Bone Resorption at the Bone-screw Interface

Clinical Orthopaedics & Related Research, 2005
In the current study, we investigated whether the systemic administration of alendronate, a third-generation bisphosphonate, suppressed the loosening of screws at the bone-screw interface. We systemically administered alendronate to rats fitted with external fixators.

Cancellous Screws Are Biomechanically Superior to Cortical Screws in Metaphyseal Bone

Orthopedics, 2016
Cancellous screws are designed to optimize fixation in metaphyseal bone environments; however, certain clinical situations may require the substitution of cortical screws for use in cancellous bone, such as anatomic constraints, fragment size, or available instrumentation.

The effect of screw holes on bone strength

The Journal of Foot and Ankle Surgery, 1997
Internal fixation devices continue to be used in the fixation of foot and ankle fractures and osteotomies. Because of the increased use of fixation techniques, postoperative care following removal of internal fixation devices assumes a vital role in the success of these procedures.

Fracture Fixation with Screws and Bone Plates

Veterinary Clinics of North America: Small Animal Practice, 1999
The treatment goal of fracture fixation is to restore the patient to normal function as quickly as possible. Fracture fixation can be accomplished by various means; fixation with screws and bone plates is not only a popular but a successful technique. In this article, the authors provide concepts that a surgeon must understand for successful screw and ...

Optimizing Bone Screw Pullout Force

Journal of Orthopaedic Trauma, 1990
Stability of internal fixation by plate and screw depends on the interface of bone and screw threads. Bone-screw thread design was tested in a synthetic bone model to determine maximum bone-screw pullout force. The model was confirmed to provide reproducible results in a clinically relevant range.
