From the Guidelines
Surgical intervention for chronic low back pain management should be reserved for patients who have failed conservative management, have specific diagnoses amenable to surgical correction, and understand the potential risks and realistic expectations for improvement. The efficacy of surgical intervention varies depending on the underlying condition, with procedures like discectomy and decompressive surgery offering faster pain relief and moderate benefits for specific conditions such as herniated discs and spinal stenosis, respectively [ 1 ]. However, for nonspecific low back pain, fusion surgery shows only modest and inconsistent benefits over intensive rehabilitation programs [ 1 ].
Key considerations in deciding on surgical intervention include:
- Careful patient selection, with best outcomes occurring when there's a clear anatomical cause matching the patient's symptoms [ 1 ]
- The potential risks of surgery, including infection, bleeding, nerve damage, and failed back surgery syndrome [ 1 ]
- The importance of patient understanding of realistic expectations for improvement, as outcomes can vary significantly [ 1 ]
In terms of guidelines, the American College of Physicians and the American Pain Society suggest referring patients with nonspecific low back pain for possible surgery after a minimum of 3 months to 2 years of failed nonsurgical interventions [ 1 ]. The British Pain Society low back pain pathway emphasizes the need for risk stratification, clarification of intensity of psychological interventions, and a logical progression for the management of sciatica, with decision points for considering structural interventions such as spinal injections and surgery [ 1 ].
Overall, the decision to proceed with surgical intervention for chronic low back pain management should be made on a case-by-case basis, taking into account the individual patient's circumstances, the underlying condition, and the potential benefits and risks of surgery [ 1 ].
From the Research
Efficacy of Surgical Intervention
- The efficacy of surgical intervention for chronic low back pain management is a topic of ongoing debate, with some studies suggesting that surgery is a reasonable option for a small proportion of well-selected patients 2.
- A study published in 2015 found that surgery is useful in only a small proportion of patients with chronic low back pain, compared to physical and cognitive-behavioral management techniques 2.
- Another study published in 2003 noted that surgery is usually reserved for patients with severe and debilitating symptoms, and can result in good outcomes with rapid return to function, but emphasized the importance of careful patient selection 3.
Comparison with Conservative Treatment
- A comparison of surgical and conservative treatment approaches found that surgery is useful in only a small proportion of well-selected patients with chronic low back pain, compared to physical and cognitive-behavioral management techniques 2.
- A study published in 2003 emphasized the importance of conservative treatment, including restoration and maintenance of functional movement, for patients who are not surgical candidates 3.
Interventional Approaches
- Interventional approaches, such as spinal injections and surgical interventions, are commonly used in the management of chronic low back pain, but their effectiveness can vary depending on the specific condition being treated 4, 5, 6.
- A study published in 2010 found that caudal epidural injections can be effective in managing chronic low back pain in patients with post lumbar surgery syndrome, with significant pain relief and disability reduction reported in a significant proportion of patients 4.
- A review published in 2018 discussed the interventional management of low back pain, including spinal injections, surgical interventions, and physical therapy, and emphasized the importance of a multimodal and multidisciplinary approach to treatment 5.
- Another review published in 2014 discussed the role of interventional pain procedures in the treatment of chronic low back pain, and found that while some procedures have been shown to be effective, others have yielded modest results at best 6.
