Summary
Lumbar total joint replacement (TJR) surgery facilitates return-to-work (RTW) for most patients within 3-6 months. Lower Oswestry disability index (ODI) scores post-surgery correlate with faster RTW, indicating improved functional outcomes.
Area of Science:
- Orthopedic Surgery
- Spinal Surgery
- Biomedical Engineering
Background:
- Lumbar fusion surgery may lead to reoperation and functional limitations.
- Lumbar total joint replacement (TJR) offers motion preservation for degenerative pathologies.
- A cohort of 32 patients undergoing lumbar TJR between 2017-2020 was analyzed.
Purpose of the Study:
- To evaluate return-to-work (RTW) outcomes after lumbar TJR.
- To identify factors influencing time to RTW.
- To assess the impact of Oswestry disability index (ODI) on RTW.
Main Methods:
- Retrospective analysis of prospectively collected data.
- Collected Oswestry disability index (ODI) at multiple postoperative timepoints.
- Utilized ANOVA, generalized linear regression, and time-to-event analyses.
Main Results:
- 100% of patients returned to work within 6 months; 96.9% by 3 months.
- Lower ODI scores at 3 and 6 months correlated with shorter RTW times.
- Kaplan-Meier analysis showed significant variations in RTW based on ODI.
Conclusions:
- Lumbar TJR shows potential for timely RTW and improved function in degenerative lumbar conditions.
- Preoperative functional status, indicated by ODI, is crucial for RTW.
- Further multicenter studies are needed to confirm safety and efficacy.
