Trial Outcomes & Findings for Study Evaluating InductOs in Diaphyseal Tibia Fractures (NCT NCT00161616)

NCT ID: NCT00161616

Last Updated: 2009-09-07

Results Overview

Patients categorized by investigator as healed, not healed, no outcome (using pre-specified criteria). Healed: no tenderness at fracture site or pain with weight bearing, presence of bridging callus or disappearance of fracture lines, no hardware failure, no secondary intervention to promote fracture healing. Not healed: diagnosis of delayed union or nonunion, hardware failure, secondary intervention procedure for fracture healing recommended or performed, or conduct of procedure that may interfere with fracture healing. No outcome: subjects who did not achieve either healed or not healed.

Participant Flow

Patients were recruited worldwide from September 2003 to July 2007.

Assessment of the fractured limb was performed 24 hours before surgical fixation. Patients were stratified by severity of fracture (using Gustilo-Anderson Classification).

PRIMARY outcome

Timeframe: 13 and 20 weeks

Population: All patients randomized were analyzed.

Patients categorized by investigator as healed, not healed, no outcome (using pre-specified criteria). Healed: no tenderness at fracture site or pain with weight bearing, presence of bridging callus or disappearance of fracture lines, no hardware failure, no secondary intervention to promote fracture healing. Not healed: diagnosis of delayed union or nonunion, hardware failure, secondary intervention procedure for fracture healing recommended or performed, or conduct of procedure that may interfere with fracture healing. No outcome: subjects who did not achieve either healed or not healed.

SECONDARY outcome

Timeframe: 1 year

Population: All patients randomized were analyzed.

Patients categorized as Success or Failure of CCRE. Success defined as a fracture judged to be both clinically healed by clinical investigator, "healed" (see primary outcome), and radiographically united by independent, blinded radiology panel, "united." Patients deemed "not healed" or "not united" were assessed as failures.
