Unequal Leg Length – Causes, Diagnosis, and Treatment

Unequal Leg Length – Causes, Diagnosis, and Treatment at Emirates Hospitals Group

At Emirates Hospitals Group, we understand that unequal leg length, also known as leg length discrepancy (LLD), can affect posture, gait, and overall musculoskeletal health. While minor differences in leg length are common and may not cause symptoms, significant discrepancies can lead to discomfort, joint pain, and mobility issues. Identifying the underlying cause is essential for proper treatment and long-term correction.

Causes of Unequal Leg Length

Leg length discrepancy can be classified into two main types:

• Structural Leg Length Discrepancy – A true difference in bone length due to:

  • Congenital Conditions – Differences in bone development present at birth.
  • Fractures or Bone Injuries – Improper healing of a broken leg bone can result in length differences.
  • Growth Plate Damage – Injuries during childhood affecting bone growth.
  • Bone Diseases – Conditions such as osteomyelitis or bone tumors that alter bone growth.

• Functional Leg Length Discrepancy – The legs are equal in length, but muscle imbalances or joint misalignments create the appearance of uneven legs due to:

  • Pelvic Tilt or Hip Misalignment – Poor posture, scoliosis, or hip instability can cause one leg to appear shorter.
  • Muscle Weakness or Tightness – Imbalances in the hip, lower back, or leg muscles affecting leg positioning.
  • Arthritis – Joint degeneration, particularly in the hips or knees, may alter leg length over time.
  • Neuromuscular Disorders – Conditions affecting muscle tone and limb positioning, such as cerebral palsy.

Diagnosis of Unequal Leg Length

A comprehensive evaluation at Emirates Hospitals Group is essential to determine the type and severity of leg length discrepancy. Diagnostic methods may include:

• Physical Examination – Assessing posture, gait, and joint mobility.
• Leg Length Measurement – Comparing actual bone lengths and evaluating functional differences.
• X-ray and CT Scan – Imaging studies to assess bone structure and identify discrepancies.
• Gait Analysis – Evaluating walking patterns to detect compensatory movements or imbalances.

Treatment for Unequal Leg Length

The appropriate treatment depends on the severity and cause of the discrepancy. At Emirates Hospitals Group, our specialists offer a range of treatment options, including:

• Physical Therapy – Stretching and strengthening exercises to address muscle imbalances and improve gait.
• Shoe Lifts or Orthotic Inserts – Customized insoles to compensate for mild leg length differences and improve posture.
• Chiropractic or Manual Therapy – Techniques to realign the pelvis and correct functional discrepancies.
• Bracing or Casting – For children with growth-related discrepancies, braces or guided growth techniques may help correct limb length.
• Surgical Intervention – In severe cases, procedures such as limb lengthening, bone shortening, or joint realignment may be required.

If you are experiencing discomfort, posture issues, or mobility limitations due to unequal leg length, seeking expert evaluation at Emirates Hospitals Group can help determine the best treatment plan for improved balance and function.
