Official title
A Prospective Non-current Concurrent Controlled Evaluation of Open and MAS® PLIF for the Treatment of Symptomatic Lumbar Degenerative Conditions
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The study is a prospective non-concurrent controlled observational evaluation of short-term operative results. As such, study sites will capture perioperative (through 6-week postoperative follow-up) case data associated with 10 standard open PLIF (posterior lumbar interbody fusion) procedures. After this open experience, these same sites will capture the corresponding data from 10 subsequent cases where the MAS (Maximum Access Surgery) PLIF variant was performed. The data from both series of cases will be compiled to identify similarities and differences between the techniques.
