OBJECTIVE Transpedicular screws are commonly and successfully used for posterior fixation in spinal instability, but their insertion remains challenging. Even using navigation techniques, there is a misplacement rate of up to 11%. The aim of this study was to assess the accuracy of a novel pedicle screw system. METHODS Thoracic and lumbar fusions were performed on 67 consecutive patients for ...

Orthopedic screw removal has proven itself to be a challenge. Access to a Screw Removal Set (TM Synthes) is essential. But what options are available when it cannot remove a broken screw in a lesser toe on a background of osteomyelitis of a lesser toe? A young healthy patient had undergone a 2nd and 3rd toe proximal interphalangeal joint (PIPJ) and distal interphalangeal joint (DIPJ) fusion usi...

BACKGROUND The purpose of this study was to compare the period of union, functional outcomes and complications of patients with femoral neck fracture treated with percutaneous cannulated screws versus dynamic hip screw (DHS). METHODS Sixty-six patients with femoral neck fracture were treated with percutaneous cannulated screws (n=33) or with DHS (n=33) between August 1999 and October 2003. Fu...

This study intended to investigate the safety and efficacy of microendoscopic discectomy system compared with anterior open approach in the treatment of odontoid fracture with cannulated screw internal fiation. Thirty-two patients (25 male and 7 female) were enrolled and randomly assigned to different treatments. 15 patients were treated with microendoscopic discectomy system (Group MED) and 17...

PURPOSE To assess an alternative technique for the treatment of midshaft non-unions of the clavicle. METHODS Five patients with symptomatic non-unions of the clavicle were treated with open reduction and intramedullary fixation by using a Herbert cannulated bone screw. Autogenous bone grafting was applied in one case and decortication in the other 4 cases. RESULTS Review of the clinical and...
