Is limb lengthening surgery done with an intramedullary nail?

In a limb lengthening procedure, the surgeon makes a controlled bone cut called an osteotomy. An intramedullary nail is placed within the marrow canal and secured so the bone segments remain aligned. A mechanism in a lengthening nail allows the segments to move apart gradually after an initial healing interval, encouraging new bone to form in the space. Not every patient or bone is suitable for this approach. The choice depends on the bone involved, alignment, growth potential, soft tissues, joint movement, previous operations, and the device available. External fixation or another method may be considered when an internal nail is unsuitable.

Before choosing surgery, ask how the target length is set, how the nail will be adjusted, and which imaging checks are needed. Discuss weight-bearing limits, physiotherapy, nutrition, return-to-work planning, and possible later nail removal. Daily stretching and joint movement may be prescribed to protect function while the bone changes. Arrange local follow-up if you will travel after surgery; the adjustment period and healing checks require coordinated care.

Seek urgent assessment for sudden severe pain, a cold or pale foot or hand, new weakness, loss of sensation, chest pain, or breathing difficulty. Contact the surgical team promptly for fever, wound drainage, increasing redness, calf swelling, or pain that is not controlled. Report a new fixed joint position or difficulty following the movement plan early, because stiffness can interfere with rehabilitation.

Why is an internal nail suitable for my bone? What alignment and length are realistic for my anatomy? How often will imaging be checked? What weight can I place through the limb? Which warning signs should make me stop the adjustment and call?
