As we get older, all individuals hope to keep their mobility, freedom and independence. Day to day tasks, such as walking to get the mail or standing to cook dinner can become laborious or even impossible, often due to a diagnosis of Lumbar Stenosis. On Friday, March 23rd, 2018, Dr. Qu, a pain management surgeon, became one of the first Physicians in the region to offer a minimally invasive solution to patients suffering from this disease. Dr. Qu completed the MILD procedure, which stands for minimally invasive lumbar decompression, a state of the art procedure recently developed by Vertos Medical.

Lumbar spinal stenosis (LSS) is a condition that affects most older individuals, and is a degenerative, age-related narrowing of the lower spinal canal that is diagnosed in more than 1.2 million individuals in the U.S. each year. Most people over 50 are affected, especially if you suffer with back pain, leg pain, numbness and tingling that is worsened while standing and walking.

Previous surgical treatments involve invasive back surgeries with significant downtime and general anesthesia. Because of this, Vertos developed the minimally invasive lumbar decompression (MILD procedure) to help treat this growing population of patients who are saying no to more invasive, spine destabilizing and costly surgeries. MILD is a Minimally Invasive Lumbar Decompression, in which Dr. Qu provides space for the narrowed nerves by using a 5.1mm portal with no incisions, sutures or overnight stays.

Dr. Qu

I wanted to be among the first physician in this entire area to bring this innovative and life altering procedure to my patients. The idea of giving someone the ability to stand and walk ten times longer with less back pain and nerve pain in only 30 minutes seemed amazing to me. At Pennsylvania Pain & Spine Institute, we pride ourselves on being on the cutting edge of minimally invasive pain treatments and surgeries.

mild™ has been performed on over 20,000 patients and has been proven to be safe and effective in 12 clinical studies and more than 20 peer-reviewed journal articles. Clinical trials demonstrate that mild™ can help LSS patients stand longer and walk farther with less pain!

mild™ proven long-term efficacy


Standing time increase:
From 8 min. to 56 min.


Walking distance increase:
From 246 ft. to 3,956 ft.

This therapy isn’t only an advancement for pain therapy but has a far reaching impact on public health by reducing the dependency on opioids for the treatment of chronic conditions.
