Zimmer® MotionLoc® in Distal Tibia Fractures

Completed
Conditions
Distal Tibia Fractures
Interventions
Device: Zimmer MotionLoc Screw
Registration Number
NCT02717546
Lead Sponsor
Zimmer Biomet
Brief Summary

The objective of this observational prospective study is to systematically document the clinical outcomes of Zimmer MotionLoc Screws for Periarticular Locking Plate System applied to distal tibia fracture treatment and confirm safety and performance of the screws.

Detailed Description

Primary Endpoint:

* Radiographic \& clinical fracture healing at 3 months post-surgery.

Secondary Endpoints:

* Complications

* Radiologic \& clinical fracture healing at 6 weeks, 3, 6, and 12 months post-surgery.

* Callus size \& distribution at 6 weeks, 3, 6, and 12 months post-surgery.

Radiologic fracture healing is defined as bridging of three of the four cortices as seen on x-ray/CT. Clinical healing will be assessed using the Function Index for Trauma (FIX-IT). The FIX-IT instrument quantifies clinical healing by assessing weight-bearing and fracture site pain on an ordinal scale. It has been initially validated in patients with tibia and femur fractures.

Callus size of the anterior, posterior, and medial aspect will be assessed for each time point using a validated and published computational method.

Primary Outcome Measures
NameTimeMethod
Average Clinical Fracture Healing of the Tibia Using the Function Index for Trauma (FIX-IT) Score at 3 Months Follow-up3 months

This measure will be assessed using the Function Index for Trauma (FIX-IT). The instrument quantifies clinical healing by assessing weight-bearing and fracture site pain on an ordinal scale. Minimum (worst) score possible is 0 and Maximum (best) score possible is 12.

Number of Participants With Radiographic Fracture Healing of the Tibia at 3 Months Follow-up3 months

Radiographic fracture healing is defined as bridging of three of the four cortices (as seen on x-ray/CT).

Secondary Outcome Measures
NameTimeMethod
Complications12 months

Adverse Events were summed for all time points for the totality of the study. I.E. - complications reported for all sites at 6 weeks, 3 months, 6 months, and 12 months were summed and reported as a single secondary outcome measure for the study.
