Limb Lengthening with External Fixator or Magnetic Nailing

Limb lengthening is a surgical procedure used to increase the length of a bone, typically in the leg or arm. It's used to correct limb length discrepancies, treat deformities, or increase height. Two common methods are external fixators and magnetic nailing.

Limb Length Discrepancies: Differences in leg or arm length due to congenital conditions, trauma, or previous surgeries.
Deformity Correction: Correcting angular, rotational, or translational deformities.
Achondroplasia or other skeletal dysplasias: To increase height and improve function.
Nonunions or Malunions: To correct fractures that fail to heal or heal improperly.

Corticotomy/Osteotomy: A controlled surgical cut is made in the bone.
Device Placement: The external fixator or magnetic nail is inserted.
Lengthening Process:
External Fixator: The frame is adjusted according to a prescribed schedule.
Magnetic Nailing: The external magnetic device is used to lengthen the nail.
Consolidation Phase: The new bone is allowed to strengthen.
Device Removal: The external fixator or magnetic nail is removed once healing is complete.

Prolonged Treatment: The lengthening process can take several months.
Physical Therapy: Rehabilitation is crucial for maintaining joint mobility and muscle strength.
Pin Site Care (External Fixator): Meticulous care is essential to prevent infection.
Pain Management: Pain medication is prescribed.
Activity Restrictions: Certain activities are restricted during healing.
Follow-up: Regular follow-up appointments are necessary.

Limb lengthening is a complex procedure with a long recovery period.
There is a risk of complications, including infection, nerve damage, and joint stiffness.
The choice between external fixators and magnetic nails depends on the patient's individual circumstances.
