History of Present Illness

• Chief complaint: Unilateral radicular arm pain in [C_] distribution, dermatomal
• Failed conservative management
• Ideal: posterolateral/foraminal soft disc or foraminal stenosis causing single-level unilateral radiculopathy — posterior decompression preserves motion, avoids fusion and anterior approach risks
• Not ideal: central disc, myelopathy, kyphosis, axial-dominant pain, instability

Past Medical History

• Standard PMH, prior cervical surgery, smoking

Imaging Review

MRI

• Foraminal/posterolateral compression at [C_-C_], lateralized to symptomatic side, exclude central compression/myelopathy

  CT

• Foraminal bony stenosis, uncovertebral/facet osteophytes

  X-ray (flexion/extension)

• Alignment, no instability

Labs

• CBC, BMP, Coags, Type and screen

Neurological Examination

• Focused [C_] myotome/dermatome/reflex, Spurling test, rule out myelopathy

Surgical Planning

Case Logistics, OR Needs & Orders

• OR table/bed: Wilson frame, Andrews/knee-chest frame, or Jackson/open-frame table by surgeon preference; flexion opens the interlaminar window and the abdomen must hang free.
• OR setup: radiolucent/Jackson table, fluoroscopy or O-arm/navigation, microscope/loupes for decompression, implant trays/graft ready for fusion, neuromonitoring for myelopathy/cord-risk cases, and postop brace plan confirmed.
• Special needs: arterial line/Foley/type-screen for long fusion/corpectomy, no long paralytic when MEPs are used, MAP/normotension for myelopathy or cord-risk cases, antibiotic redosing, and anticoagulation/DVT plan.
• Immediate postop orders: neuro checks by myotome/sensory level, airway/dysphagia watch for anterior cervical cases, CT/X-rays per construct, drain care, brace/activity orders, DVT prophylaxis timing, bowel regimen, and PT/OT mobilization.

Position

• OR table/bed: Wilson frame, Andrews/knee-chest frame, or Jackson/open-frame table by surgeon preference; flexion opens the interlaminar window and the abdomen must hang free.
• Prone (Mayfield) or sitting (some surgeons — less bleeding, but VAE risk); neck flexed; reverse Trendelenburg
• IONM optional

Approach: Posterior, Tubular (MIS) or Open Midline/Paramedian

Key Surgical Steps

1. Fluoroscopic level localization
2. MIS: paramedian stab, sequential tubular dilators docked on the lamina-facet junction of the symptomatic side; Open: small midline/paramedian incision, unilateral subperiosteal dissection
3. Identify the “V-point” — junction of superior and inferior laminae at the medial facet
4. Laminoforaminotomy: high-speed drill + Kerrison to remove medial edge of the lamina and medial ~1/3 of the facet (preserve > 50% of facet to avoid instability) over the exiting nerve root
5. Identify and decompress the exiting nerve root; follow it into the foramen, remove osteophyte/foraminal stenosis
6. Soft disc: gently retract the root superiorly, remove the disc fragment from the axilla/under the root (minimal root retraction — root is taut)
7. Confirm root is decompressed and mobile
8. Hemostasis (epidural veins — bipolar/Gelfoam), closure (tube removed; minimal closure for MIS)

Critical Anatomy & Structures at Risk

1. Exiting nerve root — gentle handling, taut root
2. Vertebral artery (anterior to foramen — do not drill too far ventral/lateral)
3. Spinal cord/dura (medial — avoid)
4. Facet joint — preserve > 50% (instability if over-resected)
5. Epidural venous plexus (bleeding)

Equipment

• Tubular retractor system (MIS) or standard retractors
• High-speed drill, fine Kerrison rongeurs, nerve hooks, micro-instruments
• Fluoroscopy, bipolar, hemostatic agents, microscope/loupes/endoscope

Monitoring

• Optional EMG/SSEP; precordial Doppler if sitting

Anesthesia

• General; if sitting → VAE precautions; standard

Potential Complications

1. Nerve root injury (retraction)
2. Vertebral artery injury (over-ventral drilling)
3. CSF leak (dural injury), epidural hematoma
4. Instability (excess facet removal), inadequate decompression/recurrence
5. VAE (sitting)

Operative Note Template

Preoperative Diagnosis: [Left/Right] [C_] cervical radiculopathy from foraminal [soft disc/spondylosis] at [C_-C_]

Postoperative Diagnosis: Same

Procedure: [Left/Right] [minimally invasive] posterior cervical laminoforaminotomy at [C_-C_] [with discectomy]

Surgeon / Assistant: Anesthesia: General endotracheal EBL / Fluids: Adjuncts: Tubular retractor (if MIS), high-speed drill, fluoroscopy, microscope; [EMG] Implants: None Complications: None

Indications: [Age]yo [M/F] with unilateral [C_] radiculopathy from foraminal/posterolateral compression at [C_-C_], refractory to conservative care — ideal for motion-preserving posterior foraminotomy. Risks (root/VA injury, instability if over-resection) discussed.

Description of Procedure: After consent and time-out, general anesthesia was induced and the patient positioned prone in Mayfield. The level was localized fluoroscopically. [MIS: sequential tubular dilators were docked on the lamina-facet junction; / Open: a small paramedian exposure was performed.] The V-point (junction of superior/inferior laminae at the medial facet) was identified, and a facet-preserving laminoforaminotomy (removing the medial ~1/3 of the facet, preserving >50%) was performed over the exiting [C_] root with the drill and fine Kerrisons.

The exiting nerve root was decompressed into the foramen and any foraminal osteophyte addressed; [a disc fragment was removed from the axilla with minimal root retraction]. The root was confirmed free and mobile. Hemostasis of the epidural plexus was obtained.

The tube was removed [/ minimal closure performed]. The patient was awakened with [improved] arm symptoms and discharged [same day/overnight].

Postoperative Plan

• Same-day or overnight; neuro checks (arm function)
• No collar/fusion; early mobilization
• Pain control, activity as tolerated
• Follow-up 2-4 weeks; expect good radicular pain relief, motion preserved

Chief-Level Case Review

Use these as the senior-level mental model for Posterior Cervical Foraminotomy (Laminoforaminotomy):

• Decision point: Localize twice and instrument once: numbering, transitional anatomy, prior hardware, rib count, navigation dataset, and fluoroscopic level confirmation are mandatory.
• Technical lever: Positioning is treatment: table choice, abdomen-free prone setup, alignment goals, shoulders/hips, eyes/plexus pressure, neuromonitoring baselines, and fluoroscopic access all change the case.
• Bailout: Protect neural elements by sequence: decompression before correction when needed, MAP support for cord risk, no long paralytic with MEPs, and immediate response to signal change.
• Postop watch: Finish with construct logic: decompression adequacy, screw purchase, alignment, fusion bed/graft, drain plan, brace/activity orders, postop CT/X-rays, and DVT timing.

Common Pimp Questions

Use these to pressure-test preparation for Posterior Cervical Foraminotomy (Laminoforaminotomy):

1. What neurologic level and root are responsible for the presenting deficit?
2. What is the decompression target and how will you know it is adequately decompressed?
3. What instability, deformity, bone-quality, or fusion variable changes the construct?
4. What vascular, visceral, dural, or neural structure is the main structure at risk?
5. What postop brace, drain, mobilization, MAP, antibiotic, and DVT plan should be ordered?
