Spondylolysis is a stress fracture in the small bony bridge (the pars) of a lower-back vertebra — a common cause of back pain in young athletes in sports with repeated bending and twisting. Caught early, it usually heals well with rest and rehabilitation. At Desert Spine and Pain in Phoenix, a dual board-certified spine surgeon and neurosurgeon confirms it and guides recovery.

Spondylolysis is a stress fracture in the pars interarticularis — a small bony bridge connecting the joints at the back of a vertebra, usually in the lowest level of the lower back. It's typically caused by repetitive hyperextension (bending backward), which is why it's common in young athletes in gymnastics, football, dance, and similar sports.
Spondylolysis often responds well to conservative care when caught early. Left untreated, a pars fracture can allow the vertebra to slip forward — progressing to spondylolisthesis — which is why confirming and treating it matters.
See a specialist for persistent lower back pain in an active adolescent or young adult — especially pain that worsens with bending backward or with sport. Early diagnosis gives the best chance of healing the fracture.
Go to an emergency room or call us immediately if you develop progressive weakness or numbness, loss of bladder or bowel control, or severe pain after a significant accident or fall.
Spondylolysis is treated least-invasive-first — the large majority heals without surgery.
The first step is pausing the aggravating activity and, when helpful, a supportive brace to let the stress fracture heal.
Physical therapy through our on-site partner BackFit Health + Spine rebuilds core strength and guides a safe, staged return to activity.
In the uncommon case a fracture doesn’t heal and pain persists or a slip develops, a fusion stabilizes the segment.
Choosing the right spondylolysis specialist in Phoenix matters. At Desert Spine and Pain, your care is led by Dr. David L. Greenwald, MD, FAANS, FACS — a physician who is both a board-certified spine surgeon and a neurosurgeon. That dual expertise is rare, and it means one expert can guide you across the full spectrum of care — from a simple injection to complex surgery — and recommend what is genuinely best for you, whether you need a spondylolysis doctor for conservative care or a surgeon when surgery is truly the answer.
A rare dual credential — so the specialist who treats you can also perform surgery if it's ever needed.
Most patients get better without surgery. We only advance when your condition truly requires it.
No referral needed. We make it straightforward to see a top spine specialist, even out-of-network.
24/7 concierge response and close coordination with personal-injury attorneys.
Life Beyond the Pain

From your first visit, the goal is a clear diagnosis and a plan built around you — not a one-size-fits-all protocol.
We listen to your history, examine you, and review any prior imaging — no referral required.
If needed, we order or review MRI/X-ray imaging and may use diagnostic nerve testing or a diagnostic injection to confirm the exact source.
Dr. Greenwald explains your options in plain language and starts with the least invasive treatment likely to work.
We deliver your care — therapy, a procedure, or surgery at an affiliated accredited facility — and follow you closely until you're back to living.
Cost and coverage shouldn't stand between you and relief. Desert Spine and Pain welcomes out-of-network patients and will walk you through what your evaluation and treatment are likely to involve before anything is scheduled — so there are no surprises. We'll help you understand your benefits and options, whether you're using insurance, paying out-of-pocket, or being treated under a personal-injury claim.
If your pain started with a car accident, slip-and-fall, or work injury, we offer a dedicated pathway: prompt evaluation, thorough documentation and records for your case, and direct coordination with your personal-injury attorney. You focus on recovering; we handle the medical side.

Book a Consultation — (602) 566-9500Will spondylolysis heal on its own?
Often, yes — especially when caught early. Pausing the aggravating activity, bracing when helpful, and physical therapy let most pars stress fractures heal without surgery.
Can my child return to sports?
Usually, yes. After the fracture settles and core strength is rebuilt, we guide a safe, staged return to sport — the goal is healing first, then a durable return.
What happens if it's not treated?
An unhealed pars fracture can allow the vertebra to slip forward, progressing to spondylolisthesis. That's why confirming and treating spondylolysis early is worthwhile.
Do I need a referral, and are you out-of-network?
No referral is required, and we welcome out-of-network patients.
