Introduction

Limb length discrepancy (LLD) occurs when one leg is shorter than the other. Even a small difference can affect posture, walking, and overall body balance.

Causes

  • Congenital conditions
  • Injury or fracture
  • Growth plate damage
  • Bone infection
  • Previous surgery

Symptoms

  • Uneven walking (limping)
  • Back or hip pain
  • Postural imbalance
  • Difficulty standing for long

How Much Difference is Serious?

  • Minor difference (1–2 cm): may not need treatment
  • Moderate to severe: requires correction

Treatment Options

Non-Surgical

  • Shoe lifts
  • Physiotherapy

Surgical

  • Limb lengthening (Ilizarov technique)
  • Bone shortening (rare cases)

Limb Lengthening Process

  • Bone is surgically prepared
  • External device is applied
  • Gradual lengthening begins
  • New bone forms naturally

Benefits

  • Corrects height difference
  • Improves walking pattern
  • Reduces pain
  • Enhances confidence

Conclusion

Limb length discrepancy is a treatable condition with modern techniques. Early diagnosis and expert care can help restore balance, function, and quality of life.
