What it is
A back-of-the-neck, motion-preserving operation for spinal cord compression across several levels. Instead of removing the bony arches (lamina) entirely or fusing the spine, the surgeon reshapes the lamina to enlarge the spinal canal — in effect creating more room for the spinal cord while keeping the bone in place and avoiding fusion. Two common techniques are the "open-door" (the lamina is hinged open on one side and held with small plates or spacers) and the "French-door" (the lamina is split down the middle and both halves are opened); both produce comparable results1.
When it's used
Laminoplasty is best suited to multilevel cord compression (myelopathy), typically 3 or more levels, in a neck that still has a reasonable forward curve (lordosis) and no significant instability or slippage2. Because the decompression relies on the spinal cord gently drifting backward into the newly created space, it is not the right choice for a fixed reversed (kyphotic) curve or for compression coming only from the front at one or two levels — those situations are usually better addressed from the front (ACDF or corpectomy) or with a fusion.
How it compares to fusion (PCDF)
Nerve and spinal-cord recovery are broadly similar between laminoplasty and laminectomy-with-fusion1. The appeal of laminoplasty is that it preserves neck motion and avoids a fusion. In comparative studies it has shown lower overall complication rates, less blood loss, shorter operations, and shorter hospital stays than fusion1. A large registry analysis found greater improvement in neck-related disability at two years with laminoplasty compared with posterior fusion, with otherwise similar outcomes2, and in a large randomized trial comparing front and back surgery for myelopathy, both approaches produced similar improvement in physical functioning3. The older worry that laminoplasty worsens neck pain has generally not held up in properly selected patients.
Risks
The most common issues are temporary neck and shoulder stiffness or aching ("axial" pain, in roughly 14% of patients) and C5 palsy — a weakness of the shoulder/upper-arm muscles that usually appears shortly after surgery and typically recovers over weeks to months (it occurs in about 4–5% of patients, and the large majority recover)4. Some gradual loss of neck motion, and uncommonly a slow change in the neck's curve, can occur over time.
Recovery
Most patients are up and walking the next day, wear a soft collar for comfort for a short period, and begin gentle neck motion and strengthening within a few weeks. Most people return to the bulk of daily activities around 3 months, with nerve recovery often continuing for up to a year or more.
