My first educational post, will be covering the basis on both femur and tibia lengthening, touching on clavicle lengthening and humerus lengthening (upper arm).
Femurs (thigh bones)
  • Typical safe range is 5 to 8 cm.
  • Heal faster than tibias due to better blood supply and more muscle coverage.
  • Quadriceps strength drops significantly during recovery.
  • Hip flexors get very tight.
  • Changes knee position relative to the rest of the leg.
  • Walking pattern must be relearned.
  • PRECICE 2 (and other models) typically inserted 1/4 through the top of the femoral shaft.

Tibias (shin bones)
  • Typical safe range is up to 5 cm.
  • Slower healing than femurs because of less soft tissue and worse blood flow.
  • Higher risk of non union compared to femurs.
  • Lengthening puts more stress on the ankles than the knees.
  • Achilles tendon tightens. Physical therapy is required to avoid a toe walk.
  • Nerve issues are more common than with femurs.
  • Some people choose tibias to keep their thigh to shin ratio looking normal.
  • Will look out of proportion without quadrilateral lengthening.

Humerus lengthening (upper arms)
  • Typical range is 4 to 6 cm.
  • Done mostly by people who already lengthened their legs and ended up with arms that look too short.
  • Recovery is less painful than legs because you do not walk on your arms.
  • Shoulder mobility decreases during treatment.
  • Triceps get weak.
  • External frames on the arms make daily tasks like dressing and typing difficult.
  • Most cosmetic lengthening patients skip this.
  • May be regrettable if patient has a short-end torso.

Clavicle lengthening (collarbones)
  • Adds shoulder width, not height.
  • Typical gain is 3 to 4 cm per side.
  • Scars are visible because the clavicles sit just under the skin.
  • Nerve damage is a real risk. The brachial plexus runs close by.
  • Some people get permanent numbness or weakness in the arms.
  • Over lengthening can cause shoulder impingement and joint problems.
  • Most limb lengthening surgeons do not offer this. You need a specialist (No Dr Paley this time).
  • Required for sub 6in framecels
  • Typically also uses PRECICE or other LL model inserts.

My first educational post, only thing I know about anyways. If mirin leave a rep. If considering LL, I'd say Dr Paley is the best shot, with >25000 procedures completed he's THE most educated and well equipped LL surgeon, though his prices are very $$$.
