A woman in her seventies lifts a bag of potting soil out of the car trunk. She feels a sharp catch in her mid-back, calls it a pulled muscle, and waits for it to ease. Two weeks later, ten minutes at the stove still sends her to a chair. A vertebral compression fracture can start with a moment that small, and plenty of people go weeks without connecting the pain to a broken bone.
How a Vertebral Compression Fracture Happens
Each bone in the spine is a block built to take weight from above. When osteoporosis thins that bone, the front edge can crack under ordinary strain, like bending to pick up a laundry basket. According to the Cleveland Clinic, a compression fracture is a break or crack in a vertebra, and a past fracture raises the risk of another. Long-term steroid medicine, smoking, and low body weight also add to the odds. Because the front collapses more than the back, the vertebra ends up thinner in front, like a doorstop.
When several vertebrae wedge forward, the upper back can tip into a rounded curve called kyphosis. That curve can crowd the chest enough to make a deep breath harder. Losing height between yearly checkups can be the first sign anyone spots.
Signs of a Vertebral Compression Fracture
Pain from a fresh fracture usually starts suddenly in the middle or lower back. A review in American Family Physician notes that the pain may begin during a cough, a sneeze, or a lift. Standing and walking can make the pain worse, and lying on the back can ease it. Pressing on the spine right over the broken bone may hurt in one small spot.
Arthritis in the spine joints, spinal stenosis, and a strained muscle are other common causes of back pain in older adults, and each can flare after heavy lifting. A fracture’s pain begins on a day someone can point to and stays focused at one level of the spine. Most of these breaks happen between the bottom of the shoulder blades and the belt line.
A Vertebral Compression Fracture With No Pain
Some fractures never hurt enough to send anyone to a doctor. More than two-thirds of people with a vertebral compression fracture have no symptoms, according to American Family Physician. In those cases, the break turns up by chance on an X-ray. A chest X-ray before surgery can show an old wedge nobody knew was there.
Even a painless fracture found on an X-ray deserves follow-up. People with a compression fracture face five times the risk of a new one, the same review reports. A primary care doctor who hears about an old wedge can start looking at why the bone gave way. Blood tests, including a vitamin D level, may be part of that search.
How an MRI Shows Whether a Fracture Is Recent
An X-ray shows that a vertebra has collapsed, though not always when the collapse happened. On MRI, a recent fracture shows swelling inside the bone. American Family Physician describes this swelling as the way doctors date a fracture. That swelling usually fades over a few months as the bone heals. For someone who cannot have an MRI, such as a person with certain pacemakers, a CT scan or a bone scan can help show whether a fracture is new.
Dating the fracture affects whether kyphoplasty is on the table at all. Kyphoplasty works by filling a fresh break with bone cement, so a fracture that has already healed leaves nothing to fill. Someone with three wedged vertebrae on X-ray may have swelling at a single level, and a surgeon would treat only that level.
The First Weeks Without Surgery
Care for a new vertebral compression fracture usually starts without an operation. Pain medicine, physical therapy, and sometimes a back brace come first. American Family Physician reports that people who choose this route have better than a 50% chance of enough pain relief. Most of that improvement arrives by three months. Doctors commonly prescribe a brace for six to eight weeks, though few studies back bracing.
Long stretches in bed can backfire, since lying still costs muscle and bone that are already weak. Someone whose pain still blocks walking, sleep, or therapy a few weeks in can book a visit with board-certified orthopedic spine surgeons. Leg weakness, numbness, or trouble controlling the bladder needs emergency care right away, because the broken bone may be pressing on nerves. A spine visit usually starts with a fresh X-ray taken standing up, which shows whether the bone has sunk further since the first image.
When Kyphoplasty Is an Option
Surgeons reserve kyphoplasty for a narrow group of fractures. American Family Physician advises waiting until an MRI confirms a recent fracture. The same guidance calls for pain or lost function lasting through at least three weeks of other care. Someone who still cannot get out of bed without help at week four sits squarely in that group. People who are improving on schedule with walking and therapy usually do not need the procedure.
During balloon kyphoplasty, a surgeon guides a needle into the broken bone using live X-ray images. A small balloon lifts the collapsed front edge, and bone cement fills the space. Within minutes the cement hardens, and pain relief can start the same day. Each treated level takes about an hour, and some people go home that afternoon.
Risks include cement leaking outside the bone and a higher chance of fractures at nearby levels. For that reason, osteoporosis treatment continues after the procedure.
Questions About a Vertebral Compression Fracture
Can Someone Walk With a Compression Fracture?
Yes, and gentle walking is part of recovery once pain allows. Short walks around the house, several times a day, keep the leg and back muscles working while the bone heals. A walker or a hand on the counter can steady the first few days. Clearing loose rugs from the walking path cuts down the risk of a fall while the spine is healing.
How Long Does a Compression Fracture Take to Heal?
Within the first few weeks, pain usually eases enough for short walks. Bone repair keeps going for about three months, and very thin bone can take longer to knit. A fracture that still hurts badly at three months calls for a fresh look, since a second fracture or a different problem may be the cause.
Is Kyphoplasty the Same as Vertebroplasty?
No. Both procedures inject bone cement into a broken vertebra. Kyphoplasty adds a balloon step first to lift the collapsed bone and make room for the cement. Cement leaks outside the bone more with vertebroplasty, according to the same review. Some surgeons choose vertebroplasty for an older fracture where a balloon cannot open the bone.
After the Fracture, the Bone Test Comes Next
Once the pain from a vertebral compression fracture settles, a bone density scan shows how thin the rest of the skeleton has become. Called a DEXA scan, the test takes about ten minutes on a padded table. If the scan confirms osteoporosis, medicine that slows bone loss can lower the chance of another break. A primary care doctor can order that scan at the next routine visit.
