Minimally Invasive Pain Management Procedures — A Complete Guide
Beyond Medication and Surgery — A Third Pathway for Chronic Pain
For patients in Lahore living with chronic pain, the conventional treatment pathway has always presented two options — manage symptoms with medication or undergo surgery to address the underlying cause. Medication provides temporary relief but does not resolve structural problems. Surgery addresses structural problems but carries significant risks, requires general anaesthesia, and demands prolonged recovery. Between these two extremes lies a category of treatments that most patients in Pakistan have never been offered — minimally invasive pain management procedures performed under imaging guidance that deliver targeted treatment directly to the pain source without surgical incision or general anaesthesia.
These procedures represent one of the most significant advances in pain medicine over the past two decades. At Alnoor Diagnostic Centre in Shadman, Lahore, we provide the full range of image-guided minimally invasive pain treatments alongside the advanced diagnostic imaging that ensures every procedure is performed with precision and clinical purpose.
What Makes a Procedure Minimally Invasive?
A minimally invasive pain procedure shares several defining characteristics that distinguish it from both conventional injection therapy and open surgery. It is performed through a small needle puncture or a tiny skin incision rather than an open surgical wound. It is guided by real-time imaging — fluoroscopy, ultrasound, or CT — throughout the procedure, ensuring the instrument reaches its intended target with precision. It is performed under local anaesthesia with mild sedation rather than general anaesthesia, eliminating the systemic risks that major surgery carries. Recovery is measured in hours to days rather than weeks to months. And it delivers treatment directly to the anatomical source of pain rather than systemically throughout the body.
This combination of precision, safety, and efficiency makes minimally invasive procedures appropriate for a wide range of chronic pain conditions — particularly in patients whose medical comorbidities make open surgery high risk, those who wish to avoid surgical intervention, and those for whom prolonged surgical recovery is not practical.
Image-Guided Nerve Root Blocks
Nerve root blocks are among the most commonly performed minimally invasive pain procedures and among the most immediately effective for specific pain conditions. When a spinal nerve root is compressed by a herniated disc or narrowed foramen, it becomes inflamed and generates radiating pain that travels along its anatomical distribution — down the leg in lumbar radiculopathy, down the arm in cervical radiculopathy.
Under fluoroscopic or CT guidance, a fine needle is advanced precisely to the affected nerve root and a combination of local anaesthetic and corticosteroid is injected directly at the site of compression and inflammation. The local anaesthetic provides immediate temporary relief that confirms the correct nerve has been targeted. The corticosteroid reduces inflammation over days and provides sustained relief lasting weeks to months. The procedure is performed under local anaesthesia, takes approximately 30 minutes, and most patients experience significant improvement within 48 to 72 hours. It is particularly effective for patients with acute radiculopathy who have not responded to oral medication and physiotherapy.
Epidural Steroid Injections
For patients with lumbar spinal stenosis or widespread nerve root inflammation affecting multiple levels, epidural steroid injections deliver anti-inflammatory medication into the epidural space — the area surrounding the nerve roots within the spinal canal. Image guidance ensures accurate placement and optimal distribution of medication to the affected spinal levels. This procedure provides meaningful relief for neurogenic claudication — the leg heaviness and pain that limits walking in stenosis patients — and for diffuse radicular pain from multilevel disease. It is performed under local anaesthesia and takes under an hour, with most patients returning to normal activities within a day or two.
Facet Joint Injections and Medial Branch Blocks
The facet joints at each spinal level are common but frequently unrecognised sources of chronic back and neck pain. Facet joint pain is characterised by deep, aching pain localised to the back or neck, worsened by extension and rotation, without the radiating nerve pain that disc herniation produces.
Under fluoroscopic guidance, targeted injections are delivered either directly into the facet joint or onto the medial branch nerves that supply it. These procedures serve a dual purpose — they confirm the diagnosis when they produce temporary significant pain relief, and they provide therapeutic benefit through the anti-inflammatory medication delivered. When medial branch blocks confirm facet joint as the pain source, radiofrequency ablation provides lasting relief by disabling the pain-transmitting nerves for months to years.
Radiofrequency Ablation
Radiofrequency ablation is one of the most effective and durable minimally invasive pain treatments available. Under image guidance, a fine electrode is positioned precisely at the target nerve — most commonly the medial branch nerves supplying degenerative facet joints or the lateral branch nerves of the sacroiliac joint. Radiofrequency energy heats the electrode tip to a precise temperature, disabling the nerve’s ability to transmit pain signals without affecting surrounding structures.
The procedure provides pain relief lasting six months to two years in the majority of well-selected patients — a duration that far exceeds what injectable treatments achieve — and can be repeated when the nerve eventually regenerates and pain returns. It is performed entirely under local anaesthesia, requires no hospitalisation, and most patients notice meaningful improvement within two to four weeks as the nerve response settles.
Vertebroplasty and Kyphoplasty
Osteoporotic vertebral compression fractures cause sudden, severe back pain that can be completely disabling in elderly patients. Standard pain medication frequently provides inadequate relief for this specific pain mechanism. Vertebroplasty and kyphoplasty are image-guided procedures in which medical-grade bone cement is injected directly into the fractured vertebral body under fluoroscopic guidance, stabilising the fracture and eliminating the pain it generates.
The difference between the two is that kyphoplasty uses an inflatable balloon to first create a cavity within the fractured vertebra and partially restore its height before cement is injected, while vertebroplasty injects cement directly. Both procedures take approximately one hour under local anaesthesia. Many patients experience dramatic pain relief within 24 to 48 hours — returning to mobility that was completely impossible before treatment.
Genicular Artery Embolization for Knee Pain
For patients with moderate knee osteoarthritis and active synovial inflammation who have not responded adequately to injections, genicular artery embolization addresses the vascular driver of chronic knee pain. Using microcatheter technique under fluoroscopic guidance, tiny particles are delivered into the abnormal blood vessels sustaining synovial inflammation, reducing the inflammatory activity driving pain without touching the joint itself. Pain relief develops gradually over two to eight weeks and typically lasts one to three years in appropriately selected patients.
Coeliac Plexus Neurolysis
For patients with severe abdominal pain from pancreatic cancer or chronic pancreatitis, coeliac plexus neurolysis delivers a chemical agent directly to the coeliac nerve plexus under CT guidance, interrupting pain transmission from the abdominal organs. This procedure provides sustained pain relief that dramatically reduces opioid medication requirements and improves quality of life in patients whose pain was previously inadequately controlled.
