Persistent low back pain and sciatica in the United States: treatment outcomes

Area of Science:

• Orthopedics
• Neurosurgery
• Pain Management

Background:

• Persistent low back pain (LBP) presents unique challenges distinct from acute or chronic LBP.
• Limited data exists on the effectiveness of treatments for persistent LBP.

Purpose of the Study:

• To evaluate the short- and long-term effectiveness of treatments for persistent LBP.
• To compare outcomes across different treatment modalities.

Main Methods:

• Multicenter, prospective, cross-sectional study.
• Patients with persistent LBP treated by spinal disorder specialists.
• Five treatment groups: no treatment, conservative care, immediate surgical care, delayed surgical care, and outside surgical care.
• Follow-up evaluations at 3, 6, 12, and 24 months.
• Outcome measures included pain severity, functional disability, psychologic distress, physical symptoms, and healthcare use.

Main Results:

• No-treatment group showed slight improvement in pain and healthcare use, but not function or psychologic distress.
• Conservative care group reported small, short-term improvements in pain, function, and healthcare use, with no change in psychologic distress.
• Immediate surgical care group demonstrated substantial and sustained improvement across all outcome measures.
• Delayed surgical care group showed moderate improvement, less than immediate surgery but better than conservative care.
• Outside surgical care group did not improve.

Conclusions:

• Persistent LBP does not resolve spontaneously.
• Conservative treatments by spinal specialists offer minimal benefit over no treatment.
• Immediate surgical intervention is highly effective for persistent LBP.
• Surgical outcomes vary, with timely intervention yielding the best results.
