. A foraminotomy is performed to relieve the symptoms of nerve root compression in cases where the foramen is being compressed by bone, disc, scar tissue, or excessive ligament development and results in a pinched nerve. The procedure is often performed as a

minimally invasive procedure Minimally invasive procedures (also known as minimally invasive surgeries) encompass surgical techniques that limit the size of incisions needed, thereby reducing wound healing time, associated pain, and risk of infection. Surgery by definiti ...

, the foramen can be visualized, and the impinging bone or disk material removed. Surgery is typically short in duration, taking around 6 hours. Patients stay in hospital for 5-8 nights, can drive after 8 weeks, perform light duties after 8 weeks and make a full recovery within 18 months.

Foraminectomy

A foraminotomy that removes a large amount of bone or other material may occasionally be described as a foraminectomy.
