In brief
How does height increase surgery work, and what does it involve?
Height increase surgery lengthens leg bones through a controlled bone division and gradual separation, allowing new bone to form. It requires specialist surgery, rehabilitation, imaging, and follow-up. Height gain, walking restrictions, recovery, and appearance vary; suitability must be assessed individually.

What is surgery to get taller called?
Height increase surgery, stature lengthening, leg extension surgery, and cosmetic limb lengthening describe surgery performed to increase overall height. Limb lengthening is also used for unequal limb lengths and reconstruction; evidence from those indications should not automatically be treated as cosmetic outcome evidence. [1]
How can a fully grown bone become longer?
The surgeon divides the bone in a planned location and stabilizes it. A lengthening device gradually separates the segments; new bone tissue forms in the space. After lengthening stops, that tissue must mature. The biological process is called distraction osteogenesis. This is a staged process, not an instant height change. [1] [2]
Muscles, nerves, tendons, and joints must also adapt. RNOH describes tightness, stiffness, nerve symptoms, and the need for a supervised physiotherapy plan. These issues can limit treatment even when a device still has unused extension capacity. Its guide describes one clinical pathway, not instructions for every implant. [2]
What does treatment ask of the patient?
Scroll horizontally to view every column.
| Area | Discussion to have |
|---|---|
| Monitoring | Who reviews imaging and symptoms, and who can change or stop the lengthening plan? |
| Movement | What loading restriction applies to the exact implant and current stage? How will stairs and daily tasks be managed? |
| Rehabilitation | Who provides the individualized physiotherapy plan and assesses joint movement? |
| Support | Where will you recover, who will help, and what happens if you need urgent care or extra surgery? |
| Budget | What do the written quote, follow-up, accommodation, rehabilitation, and possible later procedures include? |
Use our recovery milestone guide and written-cost comparison to organize those conversations. A clinic's advertised recovery calendar or package price is not a complete personal plan.
What are the risks?
Institutional guidance describes problems including infection, blood clots, joint stiffness, nerve or blood-vessel injury, delayed bone healing, alignment changes, and implant problems. Further surgery may be necessary. The relevance and likelihood of each risk depend on the procedure and patient; this introduction does not supply a universal complication rate. [2]
Read the complications reference and request a written escalation plan. A loading allowance is not permission to run or a promise of uncomplicated recovery; those decisions require the treating team's assessment.
How should cosmetic goals and proportions be discussed?
Discuss the goal in functional and practical terms as well as centimeters: movement, work, sport, support, and the possibility that the plan changes. The body-proportions article explains measurements without prescribing an ideal ratio. Appearance satisfaction cannot be promised from a rendering, a selected patient photograph, or a taller measurement.

Provider-produced visual context
Published February 4, 2025. The video illustrates bone division, lengthening, and consolidation. It is not PRECICE MAX-specific, an independent outcome study, or a treatment instruction. Its rate, recovery, final-bone-strength, and confidence statements are not individual guarantees. Automatic captions may mistranscribe rates or units; use the written explanation and your team's instructions. The essential mechanism is described above. [3]

How to use these sources
HSS and RNOH explain their institutional approaches. NICE's intramedullary distraction guidance explicitly excludes bilateral lower-limb lengthening for short stature. Its governance, consent, and audit recommendations concern the other indications within its scope, not a cosmetic-surgery or MAX endorsement. Videos and illustrations support comprehension, while evidence and clinical assessment support decisions. [1] [2] [4]
FAQ
Can height surgery be performed after growth plates close?
HSS describes stature-lengthening candidates as fully grown, with closed growth plates confirmed on imaging. That is one eligibility condition, not proof that surgery is appropriate for a particular adult. [1]
How many centimeters can I safely gain?
There is no safe amount this page can assign to an individual. Anatomy, soft-tissue tolerance, bone formation, implant limits, and clinical assessment all matter. See the [lengthening limits guide](/learn/library/how-much-can-you-lengthen). [1] [2]
Does an internal nail mean no scars or rehabilitation?
No. RNOH describes surgical wounds and physiotherapy with internal-nail treatment. See the [scar guide](/learn/library/limb-lengthening-scars). [2]
