Limb Lengthening Surgery:
Procedures and Recovery
Limb lengthening surgery was first developed to help children with growth conditions like dwarfism. It was also used for patients with leg deformities or bones that did not heal properly after injury. Over the years, the same methods have been refined into a cosmetic option for healthy adults who want to be taller. For many patients, it’s a life-changing decision. It can add 3 to 6 inches of permanent height through the body’s natural healing process.
The idea behind the surgery is simple, even though the work is precise. The surgeon makes a small cut in one of the long bones of the leg. Then they place a special internal device inside. Over the next few weeks and months, that device slowly pulls the two ends of the bone apart, a fraction of a millimeter at a time. The body responds by filling in the gap with fresh new bone. When the process is done, you end up with longer bones and a taller frame.
Another detail that helps the body heal faster is “seeding.” Your leg bones contain bone marrow and stem cells. During the surgery, the surgeon drills several small holes into the bone to expose the marrow. This lets stem cells and red blood cells fill the surgical area. Stem cells are the body’s specialized healers. They help form new bone, blood vessels, nerves, tendons, and ligaments. The exposed marrow also produces fresh red blood cells, which deliver oxygen to the area and accelerate healing.
The Height Lengthening Institute specializes in this surgery for healthy adults seeking a permanent height increase. Patients come from across the country to work with Dr. Mahboubian at our Burbank, California, office. We use the PRECICE Nail System to perform cosmetic height surgeries and can lengthen both legs in a single procedure. We also specialize in bone lengthening for patients who need bowleg correction, knock-knee treatment, or leg-length discrepancy correction.
This guide walks you through every part of the process. It covers who the surgery is a good fit for and how much height you can gain. It also covers what it costs, what insurance does and doesn’t cover, what the consultation entails, and what recovery really looks like over the months. You’ll also learn the risks you should understand before committing. If you still have questions, bring them to a consultation. A good surgeon would rather spend an extra hour answering your questions than have you book a surgery you’re not sure about. Take your time here.
How Much Height Can You Gain With Bone Lengthening Surgery
How much taller you can get depends on a few things. It comes down to your starting height, your bone structure, and the goals you and your surgeon set together. In general, height surgery can add anywhere from 2 to 6 inches or more.
Our height-lengthening specialist recommends a total lengthening of 2 to 3 inches (5 to 8 cm) of the thigh bone (femur). Lengthening beyond 3 inches in a single bone raises the risk of problems. We put safety ahead of pushing the maximum. If you want more height after that, a second surgery can be done about a year later in the shin bones (tibiae). This can add another 2 to 3 inches (5 to 8 cm).
The best way to set a clear goal for your own result is to talk it through with a qualified surgeon during the consultation. Based on your anatomy and goals, they can give you a realistic estimate of what’s possible for you.
The Initial Consultation: What Happens and What to Expect
The height-lengthening consultation is the first step in the process. You’ll meet with Dr. Mahboubian to learn about the surgery. You’ll talk through whether it fits your goals and figure out together if it’s right for you. The surgeon will review your medical history, perform a physical exam, and take X-rays of your legs. Then they calculate the size needed to fit the PRECICE nail system to your bones. Dr. Mahboubian then walks you through his treatment plan, sets clear goals, and answers your questions.
Many of our patients come from all over the country. We also offer online consultations for those who can’t make it to our Burbank office in person. Online consultations have limits. They restrict how well we can analyze your situation. We reserve the option for patients who truly can’t come in. In-person consultations are strongly recommended for the best results. For online consultations, X-rays are required so we can order the right nail size. The in-person consultation fee is $650. The online consultation fee is $400.
In every consultation, Dr. Mahboubian gives patients a full understanding of their situation and a complete overview of their options. This way, you can make an informed decision about your care.
The PRECICE Nail: How This Device Works
The PRECICE Nail is a newer, less invasive internal lengthening device. It can support up to 75 pounds per nail after surgery. A key advantage is that it greatly reduces post-surgery pain, discomfort, and recovery time compared to older methods.
The system is programmable. Before insertion, Dr. Mahboubian programs the device to slowly lengthen your bone to the prescribed length using remote-controlled magnetic technology. A single procedure can provide up to a 3-inch increase in height. Two procedures, one on each set of bones, can yield a total of about 6 inches.
Which Bones Are Lengthened, and Why Never at the Same Time
Dr. Mahboubian performs both femur and tibia bone lengthening procedures. Both are effective, and the right choice depends on your anatomy, proportions, and goals.
One rule is firm: we never lengthen both bones at the same time. The rate of complications (nerve damage, fat embolism, joint contracture, and others) goes up sharply when both bones are done together. Patients who want both schedule the procedures separately, usually several weeks to months apart. This is the standard for every trusted limb lengthening surgeon.
How We Safely Lengthen Bone and the Surrounding Tissue
Limb lengthening surgery starts with a small incision in the knee or hip. Next, the surgeon cuts the femur or tibia into two sections. Dr. Mahboubian inserts the PRECICE nail into the center of the bone and secures it with locking screws before closing the incision.
The distraction phase takes place over the next few weeks to months. The separated bone pieces are slowly stretched apart, a fraction of a millimeter at a time. As they separate, your body generates new bone tissue, blood vessels, and nerves to fill the space. That new growth is what adds three to six inches to your overall height.
Scheduling Limb Lengthening Surgery: What to Expect
Scheduling information is available for patients who have been confirmed as candidates for height lengthening surgery.
Once your surgery date is set, you’ll receive detailed instructions on pre-operative preparations. This includes required medical tests, medications to avoid, and food guidelines leading up to the day. You’ll also get clear guidance on what to expect on the day of surgery. You’ll get post-surgery care instructions and your follow-up schedule.
We encourage you to ask questions throughout the process. The scheduling phase is when many practical details come together. Things like travel, lodging, time off work, and help at home. The more you communicate with the team, the smoother the experience tends to be.
How to Know If Cosmetic Height Surgery Is Right for You
Candidates for cosmetic height surgery (also called limb lengthening or stature lengthening) are typically healthy adults. They feel unhappy with their current height and want to increase it. Realistic goals matter as much as physical readiness.
The strongest candidates share a few traits:
- Have reached skeletal maturity (usually around age 18 for women, 21 for men)
- Are generally in good health and at a reasonable weight
- Don’t smoke or use nicotine products
- Have realistic goals about what the surgery can and can’t deliver
- Are prepared for a year-long commitment to therapy
- Have a support system at home during the hardest weeks
Every candidate undergoes a full review by a board-certified limb-lengthening surgeon. This confirms they meet both the physical and mental criteria. Patients considering this surgery need to be truly motivated to improve their confidence and quality of life. They also need to understand what a year of recovery will look like before they start.
Who This Surgery Is Not Recommended For
Many articles focus on who should consider the procedure. It’s just as important to talk about who shouldn’t. This is a year-long commitment. Going in when you’re not ready leads to outcomes no one is happy with.
The situations that often raise concern:
- Active nicotine use. Nicotine slows bone healing a lot. Smoking during recovery sharply raises the risk of delayed union. This is usually a hard stop until you’ve quit.
- Uncontrolled medical conditions. Poorly managed diabetes, vascular disease, and autoimmune issues all make surgery and recovery much riskier. These need to be addressed first.
- Unrealistic goals. Some patients believe surgery will fix something that isn’t really about their height. These patients often struggle during recovery, even when the surgery itself goes perfectly.
- Untreated mental health concerns. Depression, anxiety, and body image issues are worth working through with a mental health professional before committing to a major elective procedure.
- Compliance issues. This surgery only works if the patient does their part. A pattern of missed appointments or trouble sticking with long-term medical plans puts you at higher risk of a poor outcome.
If you’re unsure whether you’re ready, the consultation is the place to sort that out.
Post-Operative Recovery After the Initial Surgery
After surgery, you go through a period of post-surgery recovery and therapy. This involves a hospital stay of several days so the team can monitor for early complications and ensure the surgical site is healing well. Physical therapy starts during this time and continues throughout the rest of your recovery.
Physical therapy plays a central role. It helps you regain strength, mobility, and range of motion. You’ll gradually increase your activity level and weight-bearing as tolerated, following a customized rehabilitation plan.
During the hospital stay, you’ll learn how to use the external remote controller (ERC) to gradually lengthen the PRECICE rod, as directed by Dr. Mahboubian. Patients cannot walk or bear weight on their legs during the first portion of the lengthening process. You’ll need mobility aids like wheelchairs, crutches, or knee scooters.
Follow-up appointments occur every 10 to 14 days. We take new X-rays, perform a physical exam, and check your healing. Changes in the lengthening rate are based on joint flexibility and bone-healing progress.
The post-surgery period is where patience matters most. Dedication to the plan and showing up for every appointment are what produce the best results.
What Recovery Feels Like, Week by Week
Patients often ask what recovery really feels like. Not the clinical summary, but the daily experience. Recovery moves through four different phases, and each one feels different:
- Early post-surgery phase (first 2 weeks): Surgical pain is most noticeable, swelling is significant, and sleep is disrupted. Getting out of bed takes planning. You’ll be tired, a little foggy from medications, and dependent on others. Patients often find this phase manageable but humbling.
- Distraction phase (2 to 3 months): Sharp surgical pain fades, but a new set of sensations takes its place. Your muscles, nerves, and connective tissue are being slowly stretched. You’ll feel tightness in the thighs or calves, occasional tingling, and fatigue that builds over the day. Physical therapy becomes the center of your routine. Skipping sessions is the single biggest reason patients develop joint stiffness later.
- Consolidation phase (3 to 4 months): This is often the longest phase and can be the most mentally tough. Your legs appear finished externally, but the new bone remains soft. Weight-bearing increases based on X-ray evidence, not on how you feel. Pushing too hard here is how patients end up with stress fractures.
- Rehabilitation phase (several more months): Strength comes back unevenly. Balance takes longer than many people expect. High-impact activities are held off until Dr. Mahboubian clears you, usually around the 12-month mark.
Going in with clear goals for each phase makes the whole year easier to navigate.
Where You’ll Be Staying During the Lengthening Phase
We recommend that patients undergoing height-lengthening stay in Los Angeles for full recovery when possible. If you can’t, we ask that you stay at least two to three weeks after surgery. That’s long enough to get through the window where post-surgery and lengthening complications are most likely to appear.
For patients who return home before the process is complete, we stay in close contact. You’ll send us your X-rays every few weeks, and we will remain available by phone, email, and chat. When needed, we coordinate your care with a local orthopedic surgeon, so you have hands-on support near home.
What Happens Once the Lengthening Phase Ends
The full height lengthening process takes up to 8 months to complete. That’s the average time it takes for the bones to heal fully. During this period, you’ll continue physical therapy to build the muscle strength needed to support your new height and regain full mobility.
Many patients can safely return to normal activities and undergo PRECICE rod removal within one year of the original procedure. Rod removal is an outpatient surgery, so no hospital stay is required. It’s a much easier recovery than the original surgery. Within a few weeks, you’re back to full activity without hardware in your leg.
The Medical Risks You Need to Understand Before Moving Forward
Limb lengthening is a surgical procedure. Even with modern techniques, it carries unique though rare risks. Understanding them honestly is part of making an informed decision:
- Infection: Surgical sites can become infected, leading to pain, swelling, redness, and fever. Prompt antibiotic treatment is needed.
- Delayed bone healing (nonunion): The new bone sometimes takes longer than expected to harden. Bone grafting is occasionally needed.
- Nerve or blood vessel damage: Nerves and blood vessels near the lengthened bone can be irritated or stretched. This can lead to numbness, tingling, impaired circulation, or deep vein thrombosis. Careful technique and close monitoring keep these risks low.
- Leg length discrepancy or joint stiffness: Lengthening can cause joint stiffness or contractures, limiting mobility. Physical therapy is essential.
- Hardware-related issues: Internal implants can occasionally cause discomfort, irritation, loosening, or breakage. Revision surgery may be needed in some cases.
- Psychological distress: Long recoveries are demanding. They can bring on anxiety or depression, especially in patients with prior histories. Counseling and mental health support can be a valuable part of recovery.
Dr. Mahboubian and The Height Lengthening Institute care team bring deep orthopedic expertise to every case, along with a genuine commitment to excellent patient care. That combination gives our patients the best chance at strong, predictable outcomes.
The Psychological and Lifestyle Side of The Height Lengthening Institute
Patients’ concerns are often focused on the physical aspects of height surgery. But in reality, the harder part is mental. A year of limited mobility, time away from work, and dependence on other people asks something from you that a brochure doesn’t capture. It’s worth thinking through before you commit.
The three areas that shape how well patients handle the year:
Goals versus reality. Limb lengthening surgery makes you taller. That’s what it delivers, and the results are real. What it doesn’t do is fix deeper worries that aren’t really about height. Patients who go in expecting a confidence boost often find one. Patients who expect the surgery to fix a relationship, a career, or a long-term sense of not being enough often feel let down, even when the surgery itself went perfectly. Being honest with yourself about your reasons matters as much as any physical check.
Motivation. The middle months are where motivation drops. Pain is mostly gone, but recovery is slow, and progress feels invisible. The patients who do best are the ones who keep showing up for therapy even when they don’t feel like it.
Adjustment period. Your new height won’t feel like yours right away. Clothes fit differently. Walking feels different. Many patients fully adjust within a few months of finishing recovery, but the shift is real. Knowing it’s coming makes it easier to settle into.
What to Think About Before Choosing Surgery Outside the U.S.
Patients sometimes ask about traveling outside the country for height surgery. The reasons are usually financial. International programs can look much less expensive, and packaged pricing is common. It’s a fair question, and it deserves a straightforward answer.
One main concern is what happens after surgery. The procedure involves a year of close orthopedic supervision. That includes X-rays every one to two weeks, changes to the lengthening rate, and watching for complications that can show up well into recovery. That level of follow-up is hard to do well when your surgeon is thousands of miles away.
Travel during recovery introduces its own risks. Long flights soon after surgery raise the likelihood of deep vein thrombosis, a serious blood clot. Return flights mid-recovery can disrupt healing. And if a complication develops once you’re back home, many local orthopedic surgeons are hesitant to manage hardware they didn’t implant. This can leave you caught between two healthcare systems at the worst time.
Cost comparisons also tend to look better on paper than they do in practice. Revision surgery, extended physical therapy, and travel for follow-up can close most or all of the price gap. The most useful question isn’t “how much does the surgery cost?” It’s “who will be responsible for my care during the next nine to twelve months?”
Whether Medical Insurance Covers Elective Bone Lengthening
Cosmetic height surgery is almost always labeled elective. This means that many health insurance plans do not cover it. In most cases, patients are responsible for the full cost of treatment. That said, some insurers do cover certain pieces. These can include medications, physical therapy, and treatment of any problems during recovery.
There are exceptions worth knowing about. Some patients have a medical condition that affects their height. If it causes functional problems or mental distress, some insurers will consider coverage as medically necessary. Coverage is also more likely if stature lengthening surgery is performed to correct a deformity or a congenital condition that affects limb length (such as bow legs). These cases are reviewed one by one. If you think you might qualify, bring your records to the consultation.
How Patients Change Physically Over Time
Many of our femur lengthening patients have added up to 3.1 inches (8 cm) to their height with a single surgery. Patients who also have height surgery on their tibias gain an additional 2.5 inches (6.5 cm). Combined, that’s a potential total of about 5.6 inches of permanent height gain, spread across two separate surgeries with recovery in between.
For many patients, that kind of change is meaningful. It shifts how clothes fit, how you carry yourself, and how you move through everyday situations. The results are also permanent. Unlike most cosmetic procedures, there’s nothing to maintain once you’re healed. The bone is simply longer.
The question worth sitting with isn’t whether the numbers are real. They are. It’s about whether a 5- to 6-inch change is worth the year of recovery, the cost, and the commitment it takes to get there. That answer is personal, and it’s one of the main things a good consultation is built to help you figure out.
How The Height Lengthening Institute Approaches Cosmetic Height Surgery Differently
The Height Lengthening Institute is an orthopedic and limb lengthening center based in the Los Angeles area, focused on cosmetic height surgery. Patients travel from across the country for evaluation, treatment, and follow-up care at a single program. The team takes a structured, patient-centered approach, with time set aside for education, planning, and ongoing support throughout the process. Each treatment plan is built around the patient’s goals, health, and timeline, with close monitoring at every stage of lengthening and recovery.
What that means in practice: you’re not rushed through a consultation, fit into a template, or handed off to someone else once surgery is over. The same team that plans your procedure also guides you through the full year of recovery. For a commitment this long, that continuity matters.
The Expert Behind Our Cosmetic Height Surgery Program
Dr. Shahab Mahboubian completed his training in limb lengthening and deformity correction at the Hospital for Special Surgery in New York. That’s the top-ranked orthopedic hospital in the country, according to U.S. News & World Report. He brought his specialized practice to the West Coast and was the first orthopedic surgeon to perform cosmetic limb lengthening using the PRECICE nail system. In addition to cosmetic height surgery, he treats bow legs, knock knees, upper- and lower-extremity deformities, leg-length discrepancies, and bony malunions and nonunions.
With a background in osteopathic medicine, Dr. Mahboubian received specialized training focused on the musculoskeletal system. This shapes how he approaches patient care. Known for his approachable and professional manner, he makes sure every consultation gives patients a full understanding of their condition and treatment options, so they can make informed decisions.
Dr. Mahboubian developed an interest in limb lengthening toward the end of his orthopedic residency, and he’s focused on helping patients in this area ever since. Beyond the physical change in height, he’s seen his patients gain confidence and reach goals they’d carried for years.
If you’re considering height lengthening surgery, the best next step is a consultation. We’ll review your goals, your health, and whether the surgery is right for you. You’ll leave with a clear picture of what’s involved, no pressure attached. Reach out to The Height Lengthening Institute to schedule a consultation.
