What this means for patients
Trauma, infection, bone loss or previous surgery can leave differences in lower-limb length, foot height or alignment. Evaluation measures the discrepancy and identifies where it originates, while considering joint function, soft tissues and any ongoing infection. Planning may involve support or a shoe modification, realignment, lengthening or staged reconstruction. Treatment is individualized to the bone and soft-tissue problem rather than the measured difference alone.
Find where the difference begins
After trauma or reconstruction, a perceived leg-length difference may come from shortened bone, joint position, loss of foot height or a combination. Measurements and imaging identify the level of the problem and any associated angular deformity before a correction is planned.
Bone loss and infection change the priorities
A defect after trauma, infection or previous surgery is more complex than a length measurement. Assessment includes infection control, bone healing, circulation and the soft-tissue envelope. Reconstruction may need several stages, and restoring a stable limb can take priority over exact length matching.
Compare support with reconstruction
A shoe lift or other modification may be appropriate in selected cases. Surgical options can include realignment or gradual lengthening with internal or external fixation. Rehabilitation and follow-up track new bone formation, joint movement and tissue tolerance; the plan must reflect the individual defect.
Questions for your consultation
- Where does the length or height difference originate?
- Is infection or incomplete bone healing still present?
- Would correction require staged reconstruction?
