Limb length discrepancy (LLD) occurs when one leg or arm is shorter than the other, leading to imbalance, gait abnormalities, and potential joint complications. In children, this condition can be present at birth (congenital) or develop due to injury, infection, or medical conditions affecting bone growth.
Early diagnosis and appropriate treatment are crucial to ensuring proper function, preventing long-term mobility issues, and maintaining symmetry as the child grows.
Causes of Limb Length Discrepancy
Congenital Causes
- Fibular Hemimelia – A condition where part of the fibula is missing, leading to leg length differences.
- Congenital Short Femur – A developmental issue where one femur is shorter than the other.
- Hemihypertrophy – A rare condition where one side of the body grows more than the other.
Acquired Causes
- Fractures & Growth Plate Injuries – Damage to a growth plate can cause one limb to grow slower than the other.
- Bone Infections (Osteomyelitis) – Severe infections in childhood can affect bone growth.
- Neuromuscular Conditions – Disorders such as cerebral palsy can lead to uneven limb development.
Signs & Symptoms of Limb Length Discrepancy
- Uneven gait or limping
- Difficulty walking or running
- Postural imbalances
- Lower back, hip, or knee pain due to compensatory posture
- Observable difference in leg or arm length
Diagnosis of Limb Length Discrepancy
- Physical Examination – Measuring limb lengths and assessing gait patterns.
- Imaging Tests – X-rays, CT scans, and MRI are used to determine bone growth and structural differences.
- Growth Prediction Analysis – Specialised tests predict how the discrepancy may progress as the child grows.
Treatment Options for Limb Length Discrepancy
Non-Surgical Treatment
- Shoe Lifts & Orthotics – Help correct minor discrepancies and improve posture.
- Physiotherapy & Strength Training – Supports muscle balance and mobility.
- Growth Monitoring – Regular check-ups ensure the discrepancy is not worsening over time.
Surgical Treatment
- Epiphysiodesis – A minimally invasive procedure that slows growth in the longer limb to allow the shorter limb to catch up.
- Limb Lengthening Surgery – Using techniques like external fixators or internal lengthening devices (e.g., Precice Nail) to gradually increase bone length.
- Bone Shortening Procedures – In select cases, shortening the longer limb may be considered to achieve balance.
