Clinical Outcome Study of the Triad Allograft for Posterior Lumbar Fusion

Pain Clinical Trial

Official title: Clinical Outcome Study of the Triad Allograft for Posterior Lumbar Fusion

Status Completed

Clinical Trial Summary

The purpose of the study is to prospectively measure pain, function, and patient satisfaction in 70 consecutive patients treated by lumbar fusion using the Triad allograft. Results of the Triad allograft will be compared to those of other anterior lumbar interbody fusion (ALIF), transforaminal lumbar interbody fusion (TLIF), and posterior lumbar interbody fusion (PLIF) surgeries. Patient participation is based on the physician determination that the patient requires one of these surgeries. Participants will be evaluated pre-operatively and post-operatively at 3, 6, 12,and 24 month intervals. Clinic procedures will be related to standard of care except for the completion of several study questionnaires:

1. Back Pain Questionnaire;

2. Oswestry Disability Index Questionnaire;

3. Short Form-36 (SF-36) Survey;

4. Visual Analog Pain Scale (VAS); and

5. The Modems Patient Satisfaction Survey.

Outcome Measurements:

1. The patient's pain is scored by a VAS normalized to 100;

2. Patient function is based on Oswestry scores;

3. General health is assessed by SF-36 completion; and

4. Overall patient satisfaction will be determined by the completion of the Modems.
