Brief Summary:
To establish an observational registry for systematic collection of clinical data from Renaissance-guided spine surgeries.

Condition or disease
Degenerative Spine Disease Spinal Deformity

Detailed Description:

The key objective of this observational registry is to prospectively collect data to facilitate the quantification of potential short- and long-term benefits of Renaissance-guided spine surgery. It establishes a common framework for collaboration between surgeons performing Renaissance-guided spine surgeries in either minimally invasive (MIS) or open surgical approaches.

The main endpoints that will be collected are surgical endpoints (e.g. complication rates), patient reported outcomes (e.g. VAS, ODI), imaging parameters (e.g. coronal and sagittal alignment, mainly in reconstructive surgeries for spinal deformities) and technical parameters (e.g. use of intraoperative fluoroscopy, ratio of planned vs. executed screws).

Study Type : Observational [Patient Registry]
Actual Enrollment : 93 participants
Observational Model: Case-Only
Time Perspective: Prospective
Target Follow-Up Duration: 10 Years
Official Title: Prospective, Observational Registry of Renaissance-guided Spine Surgeries
Study Start Date : February 2015
Actual Primary Completion Date : December 30, 2016
Actual Study Completion Date : December 30, 2016

Primary Outcome Measures :
  1. Clinical outcomes as measured on plain radiographs [ Time Frame: Within 10 years of surgery ]
    sagittal and coronal alignment in reconstructive surgeries for spinal deformities

  2. Surgical complications [ Time Frame: Within 10 years of surgery ]
    new neural deficits, implant-related durotomy, infection requiring return to surgery, excessive blood loss

  3. Reoperation rates [ Time Frame: Within 10 years of surgery ]
    Any revision surgery on the segment of interest

  4. Radiation exposure [ Time Frame: Day of surgery ]
    Reading of exposure in seconds (and KvP if available) from C-arm or other imaging system used in the operating room

Secondary Outcome Measures :
  1. Clinical performance of instrumentation technique [ Time Frame: Day of surgery ]
    implant instrumentation time, total surgery time

  2. Ratio of executed vs. planned screws [ Time Frame: Day of surgery ]
    Number of screws planned for Renaissance-guided insertion, but instead inserted manually, and cause

  3. Number of abandoned screws [ Time Frame: Day of surgery ]
    the number of screws not instrumented and the reason

  4. Neuromonitoring events [ Time Frame: Day of surgery ]
  5. Length of convalescence [ Time Frame: within 2 years of surgery ]
    Length of hospital stay, destination at discharge, time to return to work, time to return to normal activities

  6. Improvement in health-related quality of life metrics [ Time Frame: up to 10 years post-operative ]
    back and leg VAS, Oswestry Disability Index (ODI), SRS22, EQ-5D-5L, in accordance with the surgeon's practices

  7. Fusion rates/pseudoarthrosis [ Time Frame: Within 1 year of surgery ]
    The rate of fusion as determined within one year of surgical procedure.

  8. Implant placement accuracy [ Time Frame: Within one year post-surgery ]
    Accuracy of implants as measured on a post-operative CT scan (when available)
