Out of nearly 500,000 spinal fusion surgeries performed each year in the United States, very few result in serious or life-changing complications. A new study suggests one of those potentially serious complications associated with fusion surgery, the risk of blindness, has significantly decreased since the late 1990s.
Researchers at the University of Illinois at Chicago looked at data available from the Nationwide Inpatient Sample for a 14-year period from 1998 to 2012. After looking at diagnostic codes that would indicate any post-surgery complications, it was discovered that instances of blindness had decreased approximately 60 percent over that period.
The study looked at data from nearly 3 million procedures and noted 257 instances of optic nerve damage. Since prior studies were much smaller, this new data is significant since it paints a clearer picture for doctors and patients. Researchers discovered several contributing factors that tend to be related to instances of blindness linked to fusion surgery, including:
The shift towards minimally invasive surgical procedures is one of the main reasons for the sharp decrease, according to UIC researchers. More surgeons are opting to use smaller incisions to insert surgical instrumentation and required fusion-related hardware, which reduces the trauma to surrounding muscles and tissues and decreases the risk of injury to nerves. Improvements in how anesthesia is administered and monitored were also cited as a reason for the significant decline.
Statistics like this could help patients and their doctors when fusion surgery becomes one of the only options for pain relief. Barring a medical emergency, fusion surgery is a last resort and only considered if other treatments are ineffective.
Susceptibility to complications depends on several factors, including overall health and whether or not underlying conditions such as high blood pressure and type 2 diabetes are involved. Due to advances in technologies, fusion procedures today are often less invasive and safer for the majority of patients.
