NCT ID: NCT01613144 Completed - Osteoporosis Clinical Trials

OsseoScrew Versus Fenestrated Pedicle Screws Augmented With Polymethylmethacrylate

EVOLVE
Start date: May 2012
Phase:
Study type: Observational

The purpose of this clinical investigation was to collect clinical evidence of the safety and efficacy of the OsseoScrew System. The OsseoScrew System is intended to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion. The study was designed to compare the safety and efficacy of OsseoScrew compared to any other commercially available fenestrated pedicle screw system augmented with PMMA for posterior spinal fixation after surgical correction of spinal deformity or pathology.

NCT ID: NCT01144208 Completed - Clinical trials for Distal Radius Fractures

The Influence of Local Bone Status on Complications After Surgical Treatment of Distal Radius Fractures

Start date: February 2007
Phase: Phase 4
Study type: Observational

The purpose of this study is to evaluate if poor bone quality increases the risk of specific types of treatment complications in patients with distal radius fractures treated with open reduction and Locking Compression Plates(LCP).

NCT ID: NCT01143675 Completed - Clinical trials for Proximal Humeral Fractures

Influence of Local Bone Status on Complications After Surgical Treatment of Proximal Humerus Fractures

Start date: March 2007
Phase:
Study type: Observational

The purpose of this study is to evaluate if poor bone quality increases the risk of specific types of treatment complications in patients with proximal humerus fractures treated with open reduction and angle-stable plates (Proximal Humeral Internal Locking System - PHILOS).

NCT ID: NCT00748670 Terminated - Jaw, Edentulous Clinical Trials

Treatment With Fixture Microthread™ in Patients With Poor Bone Quality and no Teeth in the Upper Jaw, When Using Two-Stage Surgery

Start date: September 1999
Phase: N/A
Study type: Interventional

The primary objective of the study is to evaluate the long-term survival rate of individual implants and prostheses when treating edentulous upper jaws of poor bone quality with Fixture MicroThread™ (Micro-Macro). Clinical study recruitment was stopped in year 2000 due to a decision to modify the product under study. This was a result of feedback regarding the subjective feeling during the installation procedure. There were no safety concerns w/r to the study products. Patients already included and treated in the study were monitored for the full duration of the study in accordance with the clinical study protocol.
