Allied Pain & Spine Institute is proud to offer a comprehensive 12-month clinical fellowship training program in interventional pain, spine, and musculoskeletal medicine, beginning in July 2021.

The fellow will be educated and trained in refining their clinical evaluation and decision-making skills in spine and orthopedic/musculoskeletal disorders, as well as gain competence in a full array of fluoroscopy-guided spine and peripheral interventions (cervical, thoracic, lumbar/sacral, peripheral nerve, and joint), including neuromodulation.  Other key elements of the fellowship training include electrodiagnostics, radiographic/MR imaging assessment, musculoskeletal and peripheral nerve ultrasound (for injection guidance and diagnostics), and regenerative medicine – including PRP, platelet lysate, and bone marrow aspirate. Learning to function within a multidisciplinary team-focused environment will be emphasized, and opportunities to work with and learn from several members of the multidisciplinary care team – including chiropractors, physical therapists, acupuncturists, pain psychologists, interventional physiatrists and anesthesiologists, and spine and orthopedic surgeons – will be available.

Clinic Responsibilities

The fellow evaluates and manages a wide range of physical medicine cases including spinal disorders and pain, joint and soft tissue disorders and pain, central pain (e.g., complex regional pain syndrome), and neuropathies.  There will be significant exposure to occupational and sports medicine, with a mix of acute, subacute, and chronic cases, as well as some preventive/wellness care and performance and functional optimization.

Fluoroscopy-guided Procedures

The fellow’s training will involve a large number of fluoroscopically guided interventional cases over the course of the year.  Fellows perform these cases under close guidance of faculty physicians, with increasing levels of independence and increasing exposure to advanced procedures as clinical training advances.

Upon completion, fellows are expected to be highly competent performing the following:

  • Lumbar/sacral epidurals (transforaminal, interlaminar, and caudal)
  • Cervical and thoracic epidurals (interlaminar and transforaminal)
  • Lumbar facet procedures (medial branch blocks, RFA, intra-articular)
  • Cervical and thoracic facet procedures (medial branch blocks, RFA)
  • Selective nerve root blocks (lumbar, thoracic, cervical)
  • Sacroiliac joint injections
  • Hip intra-articular injections
  • Spinal cord stimulator trials and implants
  • Peripheral nerve stimulator trials and implants
  • PRP and Bone Marrow Aspirate harvesting and injections

Other procedures the fellow can be expected to have exposure to include:

  • Sympathetic Blocks (cervical and lumbar)
  • Intercostal nerve blocks
  • Intradiscal procedures (discography, percutaneous decompression, PRP/stem cells)
  • Genicular, Cluneal, Suprascapular, and other peripheral nerve blocks and ablations
  • Interspinous Spacer (Vetiflex) placement

Office-based procedures:

  • Musculoskeletal Ultrasound – Ultrasound is used extensively for needle guidance in peripheral joint, intramuscular/peritendinous, and peripheral nerve block procedures, as well as for diagnostic purposes
  • Joint/bursa/trigger point injections
  • Platelet-rich plasma (PRP) therapy
  • Intra-articular hyaluronic acid injections

Other Clinical Skills:

  • EMG/NCV (for PM&R and Neurology fellows) – Fellows will maintain and enhance electrodiagnostic skills throughout the fellowship.  Fellows typically perform 2-5 EMG cases per week.
  • Anesthesia (for Anesthesia fellows) – Fellows will perform some basic anesthesia practices to maintain and enhance these skills throughout the fellowship.  This can include but not be limited to conscious IV sedation and/or MAC for pain/spine cases, nerve block procedures for orthopedic cases, and general anesthesia for simple orthopedic and spine cases in an ASC setting (no hospital coverage).

Research and Education:

  • Journal Clubs and case study reviews are held regularly to review the relevant literature.  Fellows take active part in these presentations and are expected to present in monthly rotating topics.
  • Fellows are encouraged (though not required) to be involved in at least one research project during the course of the fellowship, to be completed and submitted for presentation and/or publications.
  • Fellows take part in teaching visiting medical students and PA students that may rotate through our clinics periodically.
  • The program encourages and supports fellows to participate in regional or national academy meetings and conferences to further enhance their educational experience
  • Upon completion of training, Fellows will be eligible and encouraged to sit for the American Board of Pain Medicine (ABPM) certification exam.  Fellows should be aware that while this is a non-ACGME fellowship, ABPM is recognized by the Medical Board of California as equivalent to ACGME for board certification in Pain Medicine.

Application Process:

Potential fellows will need to have successfully completed an ACGME-accredited residency program in either PM&R, Anesthesia, or Neurology, and be board-certified or board-eligible by their respective specialty board, upon the start of fellowship training.  Applicants currently in residency must be in good standing at their respective programs and must have successfully completed USMLE Step 3 (or the COMLEX equivalent) in order to be considered. Fellows must also apply for medical licensure in California (Medical Board of California) prior to the start of fellowship training.

We are currently accepting applications for the upcoming year’s position.  To apply, please submit CV, brief personal statement, and two (2) letters of recommendation.

Selected candidates will be invited to interview with us.  An interview typically spans one full day, which allows ample time for the candidate to interact with current physicians, staff, and ancillary providers, and to observe our clinics and procedures.  ***Please note that during the current COVID-19 emergency orders, we are maintaining mandatory social distancing precautions, meaning that initial interviews may be conducted remotely, with on-site interviews delayed until such national and local mandates are lifted.

I fly in to see Dr. Petros from Southern California.  I wouldn't do so if he wasn't the best there is.  He is compassionate and has always treated me kindly. I can tell he is sincere in the way he talks to me and is diligently looking for solutions that work best with me and my chronic pain needs.  Very out of the box approach, which I appreciate these days!  I would truly recommend Dr. Petros to anyone looking for a Dr. that not only cares about you as a patient but has the confidence and skill set to get results! His office staff is friendly and caring too.  Allied Pain and Spine Institute is the Gold Standard in pain care in my humble opinion!! When I find a doctor that understands the issue and always goes above and beyond to help me, I do what I can to continue seeing them. I am so glad I found this office!!

Dr Petros is amazing!  When he uses a needle his aim is "right on".  He is also very personable, an altogether great guy.  I always find my visits to him to be very informative. I have had both sides of my degenerated back injected (epidural shots) with complete success.  He allows me to have no sedative, which is cool because his jokes and stories in the operating room are really good.  He greatly enjoys his work, and enjoys the difficult challenges of getting a needle into the right place in my back.  My arthritic knee is perhaps more straight-forward, but other doctors have failed to give me pain relief.  Dr Petros studies the structure with ultrasound before injecting it.  The result - instant relief! On my recent visit for a broken back (ski accident) the doctor and staff were very accommodating to help me make a dinner engagement shortly after my appointment.  This is definitely a five-star operation!

Wow, wonderful doctor!!! I avoid all the doctors like the plague...seriously it makes my blood pressure go up when I have to go but I chose Dr. Vaidya. My friend referred him to me, he's simply the best... TOP NOTCH!!! He turned out to be a breath of fresh air. Dr. Vaidya really stands out head and shoulders above everyone else. I usually don't write reviews but he's so outstanding that I really wanted to do it for him. He's the most honest and caring doctor I have met.  He listens and gives you full attention and committed to find the best individual solution for you. He always goes out of his way to get you the most appropriate treatment and he will make it happen. He's very knowledgeable in his field. He's very professional, friendly, personable and definitely easy to talk to. His integrity is very valuable. He's one of the sharpest and most driven individuals you will ever meet.

Simply the best doctors and staff in the area. I've fought back and neck pain for over 30 years, and Dr. Petros and his team have kept me from the operating table and able to enjoy my life. I've had injections, acupuncture, as well as back braces. He listens to my concerns, cares very deeply for my pain and discomfort, and has successfully treated everything from stenosis, pinched nerves, herniated disks, and even helped me with the symptoms from shingles and lung disease. I couldn't be happier with the care he has given me over the years.

Kaitlin Z.

Dr. Vaidya has changed my life. I am in my late 20s with chronic pain and nothing had worked until I came here. All services here are wonderful and the staff is absolutely amazing. I can't recommend enough!!

Tracy B.

I have been a patient of Dr. Vaidya for a few years after not getting what I needed from other spine and pain doctors. I was looking for a doctor who would think outside the box and come up with some other ways to treat my growing amount of pain. Between Dr. Petros and Dr. Vaidya, they have brought me to a place where my pain is better managed. And let's just talk about bedside manners! I have never met doctors in the past 23 years of this back journey of mine that has as amazing bedside manners as these guys. I have cried and laughed with the team at Allied Spine. The way that I am always greeted and promptly cared for is bar none! The front office staff, and especially Nas, has been a God sent. I would never go anywhere else.

Justin P.

I am a new patient of DR Petros and my experience was great for my first two visits so far. He really takes time to listen to your issues and provides thorough answers and treatment options. The front desk staff are all very nice and respond in a timely manner to requests. Highly recommended all around!

Lisa A.

I have seen Dr. Vaidya for about 2 years. He is an amazing doctor.the attention and care you receive is well over 5 stars. He knows who I am by my face, he knows my health history with out looking in my chart, he remembers conversations we have had at previous appointments. He truly cares for his patients. I will be moving our of state, and will travel back here each month to see doctor Vaidya. I lost my insurance over a year ago and pay out of pocket to see the doctor, it is worth every penny to be treated with respect, as a person and with care. I love all the staff and feel like I am visiting family when I come in for my appointments.
