According to data from a recently published study, undergoing cervical disc arthroplasty for cervical degenerative disc disease may be safer and result in shorter lengths of hospital stay, lower hospital charges and a lower rate of mortality compared with undergoing anterior cervical discectomy and fusion.
Researchers used the Nationwide Inpatient Sample to compare the results of 699,289 anterior cervical discectomy and fusions (ACDFs) and 9,910 cervical disc arthroplasties (CDAs) performed between 2005 and 2010. Patient demographics, comorbidities, perioperative complications, length of stay (LOS), total hospital charges and mortality rates were analyzed for the two groups of patients.
Data showed that, on average, patients in the CDA group were younger and had fewer comorbidities than the ACDF patients.
The researchers also found patients who underwent CDA had, on average, a lower LOS (1.56 days vs. 2.23 days; P< .0001) and a lower mortality rate (0.10% vs. 0.22%; P= .01).
The average total charges for CDA patients were lower, as well, at $39,563 compared with $43,477 for the ACDF group, according to the researchers. – by Robert Linnehan
