Deformity Correction Surgery

Overview

Limb Length Discrepancy (LLD) Correction is a specialized orthopedic procedure performed to correct significant differences in the length of the legs or arms. While small differences are common and often harmless, larger discrepancies can lead to pain, abnormal gait, pelvic tilt, spinal imbalance, and early joint degeneration.

Advanced surgical techniques allow gradual and precise correction, restoring symmetry and function.

What Is Limb Length Discrepancy?

Limb length discrepancy occurs when one limb is shorter than the other. It may be caused by:

• Congenital conditions

• Growth plate injury

• Previous fracture

• Bone infection

• Tumor surgery

• Mal-union after fracture

Symptoms may include:

• Limping

• Lower back pain

• Hip or knee pain

• Uneven shoe wear

• Fatigue while walking

When Is Surgery Recommended?

Surgery is considered if:

• Limb difference is more than 2–3 cm

• Progressive discrepancy in children

• Functional limitation

• Pain due to imbalance

• Cosmetic concern with significant asymmetry

Mild differences may be managed with shoe lifts.

Surgical Techniques for Correction

1️⃣ Limb Lengthening Surgery

Bone is carefully cut (osteotomy), and gradual distraction is performed using:

• External fixator systems

• Internal lengthening nails

Bone regenerates naturally in the gap over time.

2️⃣ Acute Shortening or Realignment

In selected cases, shortening of the longer limb may be considered.

3️⃣ Combined Deformity & Length Correction

For patients with both angulation and shortening.

Advantages of Modern Limb Lengthening

✅ Precise and gradual correction
✅ Controlled bone regeneration
✅ Improved symmetry
✅ Better gait mechanics
✅ Prevention of spine and hip complications
✅ Improved confidence and mobility

Recovery & Rehabilitation

• Gradual lengthening phase (1 mm per day on average)

• Physiotherapy throughout treatment

• Regular X-ray monitoring

• Total treatment time depends on correction amount

• Strengthening and balance training essential

Patience and compliance are key to successful outcomes.
