Laminectomy surgery, classified under neurosurgery and orthopaedic spine surgery, aims to achieve neural decompression within the vertebral column. By excising the posterior arch of a vertebra—the lamina—and ligamentous structures such as the ligamentum flavum, the procedure alleviates mechanical compression on the thecal sac and exiting nerve roots. According to North American Spine Society (NASS) guidelines (2021), decompression surgery primary targets symptoms of neurogenic claudication and radiculopathy that fail to respond to conservative medical management.

1. Preoperative patient identification, surgical site marking, and administration of general anaesthesia.
2. Positioning the patient prone on a specialized surgical frame to decompress the abdominal cavity.
3. Midline skin incision over the target vertebral levels guided by intraoperative fluoroscopic radiography.
4. Subperiosteal dissection of the paraspinal musculature from the spinous processes and lamina.
5. Removal of the spinous process and excision of the targeted lamina using high-speed rongeurs or micro-burrs.
6. Resection of the hypertrophied ligamentum flavum to expose the underlying thecal sac and nerve roots.
7. Foraminotomy or discectomy if lateral recess stenosis or disc herniation is present.
8. Hemostasis verification, copious wound irrigation with sterile saline, and layered anatomical wound closure.

Evidence from the landmark Spine Patient Outcomes Research Trial (SPORT, Weinstein et al., 2008) demonstrates that laminectomy significantly improves leg pain, back-related disability, and overall functional status in patients with symptomatic lumbar spinal stenosis compared to non-operative treatment. Clinical benefits include relief of neurogenic claudication, improved walking endurance, reduced reliance on analgesic medications, and prevention of progressive neurological deficits such as motor weakness or bowel and bladder dysfunction.

Initial postoperative recovery occurs within the first 1 to 3 days in a hospital or ambulatory setting, focusing on pain control and early ambulation. During weeks 1 to 4, light activity is encouraged while avoiding bending, lifting, and twisting. Most patients resume desk-based work between 2 and 4 weeks. Formal physical therapy usually commences around week 4 to 6 to rebuild core stability and spinal flexibility. Full physical recovery and return to heavy labor or high-impact athletic activities typically require 3 to 6 months, guided by serial clinical evaluations.

Laminectomy surgery treats mechanical and structural nerve compression disorders of the axial spine. Key indications include lumbar spinal stenosis, cervical spondylotic myelopathy, thoracic spinal stenosis, symptomatic herniated nucleus pulposus, low-grade spondylolisthesis, spinal synovial cysts, and spinal canal tumors or epidural abscesses requiring surgical decompression.

Preoperative workup includes standing dynamic radiographs and high-resolution magnetic resonance imaging (MRI) or computed tomography (CT) myelography. Patients undergo routine blood work, electrocardiograms (ECG), and medical clearance. Anticoagulants and nonsteroidal anti-inflammatory drugs (NSAIDs) are held 5 to 7 days prior to surgery under medical supervision. Smoking cessation is advised at least 4 weeks preoperatively to enhance wound healing and reduce bone nonunion risks if fusion is performed. Patients follow standard fasting protocols (nil by mouth) starting midnight before the procedure.

Mild/Common: Transient localized incisional pain, mild muscle spasms, minor superficial wound infection (1-3%), temporary dysesthesia.
Uncommon: Dural tear with cerebrospinal fluid (CSF) leak (3-7%), epidural hematoma, deep wound infection (1-2%), position-related peripheral nerve neuropraxia.
Rare/Serious: Deep vein thrombosis or pulmonary embolism (<1%), permanent neurological injury or paralysis (<0.5%), epidural abscess, spinal instability requiring secondary fusion, systemic anaesthetic complications.

The clinical care pathway for laminectomy surgery begins with a comprehensive diagnostic evaluation, including magnetic resonance imaging (MRI) and physical examination. Preoperative clearance includes laboratory testing, medication adjustment, and cardiovascular assessment. On the day of surgery, general anaesthesia is administered, and a posterior midline incision is made to perform decompression. Following surgery, patients transition to a recovery unit where early mobilization begins within 24 hours. Post-discharge care includes structured physical therapy, pain management tapering, and systematic follow-up appointments at two weeks, six weeks, and three months postoperatively.
