Overview
Limb lengthening gradually increases bone length using external or internal devices.

Indications
Significant limb length discrepancy or deformity.

Procedure overview
The bone is cut and slowly distracted; new bone forms in the gap.

Recovery
Lengthening and consolidation take months, with careful therapy and monitoring.

Risks and complications
Infection (with external fixators), non‑union, nerve or joint problems.

Alternatives
Shoe lifts or limb shortening procedures for smaller discrepancies.
