NCT ID: NCT01016067

Last Updated: 2015-01-21

Results Overview

Overall success is reported as participants who met all of the following criteria: 1. radiographic union success; 2. success in weight bearing ability; 3. improvement in pain at the delayed healing site; 4. no serious adverse event classified as "implant-associated" or "implant/surgical procedure-associated" (device-related); 5.no additional surgical procedures classified as a failure.

PRIMARY outcome

Timeframe: 12 Months

Population: Ten investigational and 9 control subjects were evaluable for overall success while only 9 investigational and 8 control subjects completed the study at 12-month follow-up. Two subjects were classified as "failure" due to related serious adverse event or additional surgery before completion of the study.

Overall success is reported as participants who met all of the following criteria: 1. radiographic union success; 2. success in weight bearing ability; 3. improvement in pain at the delayed healing site; 4. no serious adverse event classified as "implant-associated" or "implant/surgical procedure-associated" (device-related); 5.no additional surgical procedures classified as a failure.

SECONDARY outcome

Timeframe: 12 months

Radiographic union success (a component of overall success) was defined as complete disappearance of fracture lines or the presence of bridging bone across the delayed healing site as observed on at least three of the four cortices (anterior, posterior, medial, and lateral), using plain films. If there was more than one delayed healing fracture line, all fracture lines must have been united in order to be considered a successful fracture union.

SECONDARY outcome

Timeframe: 12 months

Success in weight bearing ability (a component of overall success) was defined that subject was able to bear weight without severe pain on the affected limb. The subject was asked to stand, bearing full weight on the affected limb in a single-leg stance without ambulatory assistance for 10 seconds. If the subject was able to do so without severe pain, a positive (success) response was recorded. If the subject was either unable to stand on the affected limb in a single-leg stance or declined to do so because of limb weakness, poor balance, or severe leg pain, a negative (failure) response was documented.

SECONDARY outcome

Timeframe: 12 months

After walking five or six steps, subjects rated their intensity of pain/discomfort at the delayed healing site using a numerical rating scale from 0-10, with a score of 0 representing "no pain" and a score of 10 representing "pain as bad as it could be". Subjects who were unable or declined to walk because of severe leg pain were considered to have a score of 10. Success for pain at the delayed healing site was defined as at least a 2-point improvement in pain from the pre-operative score. Success of pain status at the delayed healing site was a component of overall success.

SECONDARY outcome

Timeframe: 12 months

The SMFA is an assessment tool that measures a subject's overall function for a broad range of musculoskeletal injuries and disorders. The SMFA results were summarized into two components, the dysfunctional index and the bother index. Success for the SMFA assessment was defined as any improvement post-operatively as compared to the pre-operative condition.

SF-36 was used to assess general health status. The SF-36 results were summarized into two components, a physical component summary (PCS) and a mental component summary (MCS). Success was defined as any improvement in a subject's SF-36 PCS post-operatively as compared to the pre-operative condition.

Subject who had a surgery after the original study treatment was classified as a treatment "failure" if the additional surgery or treatment occurred in the involved limb and affected the study treatment and/or its mechanism of action in relation to the diagnosis or condition of the subject that was the cause for having the original study treatment.
