Brief summary

The purpose of this early study is to compare the clinical results of the new Conduit Interbody device to the traditional Concorde Bullet Device. The primary objective is to explore the rates and reasons for re-operation between both constructs at 2 years.

Detailed description

The demand for lumbar fusion continues to rise with the growing and aging population. Additionally, new and innovative technologies continue to bring new devices to the market. However, our understanding of how emerging constructs compare with existing technology is lacking. The purpose of this study is to compare the clinical results of the new Conduit Interbody device to the traditional Concorde Bullet Device in lumbar fusion, one or two levels between L2-S1 will be included. Both transforaminal lumbar interbody fusion (TLIF) and posterior lumbar interbody fusion (PLIF) approaches will be included in the patient cohort. The primary objective is to explore the rates and reasons for re-operation between both constructs at 2 years.

Surgical Variables of Concorde Bullet Device versus Conduit Titanium Interbody Graft for lumber fusion2 yearsAssessment of surgical variables, such as type of bone graft or bone graft extenders (including ViviGen, bone morphogenetic protein (BMP), tricalcium phosphate, local autograft, allograft, allograft chips, or demineralized bone matrix), on reoperations

Other

MeasureTime frameDescription
Baseline Demographics of Concorde Bullet Device versus Conduit Titanium Interbody Graft for lumber fusion1 year and 2 yearsDemographics, comorbidities, will be assessed including efficacy, safety, and fusion rates. Demographics include the following: gender, age, race, BMI, weight (oz.), height (inches), ASA class, surgery level. Comorbidities include the following: diabetes, heart failure, coronary artery disease, anxiety/depression, active smoker, pre-operative opioid use.
EQ5D of Concorde Bullet Device versus Conduit Titanium Interbody Graft for lumber fusion1 year and 2 yearsThe EQ5D index scale is a 5-dimension standardized measurement of heath status developed by EuroQol. The EQ5D index is derived by applying a formula that consist of weights. It is calculated by assigning a numerical value to each response level (ie. 1 for no problem, 3 for extreme problem/unable to). The EQ5D scale ranges from 0 (worst imaginable health state) to 100 (best imaginable health scale).
ODI of Concorde Bullet Device versus Conduit Titanium Interbody Graft for lumber fusion1 year and 2 yearsThe Oswestry Disability Index is a gold standard outcome measure that was designed to assess daily function for those who experience back pain. The questionnaire consists of 10 questions presented as a 6-Likert scale. For each section the total possible score is 5; the first statement marked would score=0; the last statement marked would score=5. Scores range from 0% to 100%.
