Cannulated Screws for Pelvic Fractures
1996To better understand the classification and the rationale of management of pelvic fractures, some knowledge of pelvic anatomy and biomechanics is essential.

Expanding the applications of intramedullary cannulated screw fixation in the hand
Journal of Plastic, Reconstructive & Aesthetic Surgery, 2023Intramedullary cannulated headless compression screw fixation (ICHCS) is gaining popularity for managing metacarpal and phalangeal fractures, but is still relatively new to the surgical landscape. We aim to further illustrate its utility and versatility by presenting the outcomes of such fractures treated with ICHCS at two tertiary plastic surgery ...

Laboratory comparison of the cannulated Herbert bone screw with ASIF cancellous lag screws
The Journal of Bone and Joint Surgery. British volume, 1993The compression produced by and the resistance to pullout of the 6.5 mm cannulated Herbert screw were compared with those of ASIF headed screws. The latter were tested with and without washers and in the following sizes: 4.5 mm cortical, 6.5 mm cancellous with a 16 mm threaded segment, and 6.5 mm cancellous with a 32 mm threaded segment.

Cannulated screw with solid core insert: stronger than cannulated screws.
American journal of orthopedics (Belle Mead, N.J.), 2015We conducted a study to determine if there is a significant difference in ultimate load, yield strength, and fatigue strength between solid core screws and cannulated screws and if a solid core insert placed inside a cannulated screw would have biomechanical effects similar to those of a solid core screw.

Biomechanics of Cannulated and Noncannulated Screws
1996The bone screw is a mechanical device that converts the torque applied during its insertion into a compressive force between the two components that it is placed through, as shown in Figure 2.1. The basic nomenclature used in discussing screws is given in Figure 2.2.1 The root diameter is the diameter of the inner core of the screw, that is at the base

Cervical Pedicle Screws: Conventional Versus Computer-Assisted Placement of Cannulated Screws
Spine, 2005Prospective 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

The Journal of Bone & Joint Surgery, 1996
We retrospectively reviewed the results for thirty-four patients in whom a non-union of the scaphoid had been treated with bone-grafting and internal fixation with use of one of two types of screws as well as the temporary placement of Kirschner wires parallel to the screw to prevent rotation.

Cannulated Intramedullary Screw Fixation of Distal Fibular Fractures
Foot & Ankle Specialist, 2018Background: Open reduction and internal fixation (ORIF) methods, primarily plates and screws, remain the standard of treatment for distal fibular fractures. This study evaluates the use of a cannulated intramedullary screw as a minimally invasive treatment method for distal fibular fractures, which has not been reported in the current literature ...

Pullout Strengths of Cannulated and Noncannulated Cancellous Bone Screws
Clinical Orthopaedics and Related Research, 1997The pullout strengths of large diameter cannulated and noncannulated cancellous screws were tested in a synthetic polyurethane foam. The foam was fabricated to have mechanical properties equivalent to human cancellous bone and was characterized by compression testing before screw pullout.

Lisfranc arthrodesis for chronic pain: A cannulated screw technique
The Journal of Foot and Ankle Surgery, 1998Nine patients with injury to the tarsometatarsal joint underwent fusion with cannulated screw fixation after conservative treatment had failed. Symptoms consisted of localized pain, forefoot abduction, and progressive collapse of the medical column. Early diagnosis and treatment were associated with a better functional outcome.
