The 1,000 soldiers in this study were consecutive, non-selected cases who were sent to the roentgen (X-ray) department because of a low back complaint. By using their meticulous methodology of measurement, these authors conclude it is possible to accurately measure differences in lower extremity lengths as manifested by a difference in the heights of the femoral heads. The greatest difference in leg length measured was 44 mm, or about 1.75 inches. 
Study of Prevalence of Tibial Length Inequality on Both Sides
LLD prevalence gives an idea about the possibility of an important etiology in low back pain and hence should be emphatically considered for the evaluation of low back Pain.
Leg length discrepancy in marathon runners

It is concluded that discrepancies of 5 to 25 mm are not necessarily a functional detriment to marathon runners, and no con sistent benefits could be attributed to the use of a lift.
A relationship has been demonstrated between the LLI side and the side of LBP, and re-analysis of the sample of patients aged 34 years or less demonstrated that the LBP side is most commonly opposite theside of LLI.
Prevalence of Frontal Plane Pelvic Postural Asymmetry—Part 1
This article reviews the osteopathic medical, as well as the allopathic medical and chiropractic literature for studies that meet criteria for evidence-based comparison and examines the prevalence of six types of pelvic postural asymmetry in a consecutive case series of 421 patients with low back pain.
The treatment of femoral fractures by cast-brace and early walking: a review of seventy-nine patients.
Discrepancy in femoral length was encountered most frequently when the cast-brace was applied within the first two weeks from injury or after six weeks and in those patients with comminuted fractures of the middle third of the femoral shaft.
ORIGINAL : Effect of Leg Length Discrepancy on Gait and Cobb`s Angle
The study showed that LLD influenced deformations of the human body and walking.
Measurement and restoration of equality in length of the lower limbs in total hip replacement
Inequality of limb length can be radiologically determined before and after total hip arthroplasty and demonstrates inequality of limb functional length as it reflects the tilting of the pelvis.
The Effect of Limb-Length Discrepancy on Gait*
Children who had less of a discrepancy were able to use a combination of compensatory strategies to normalize the mechanical work performed by the lower extremities, and there was a greater vertical displacement of the center of body mass.
Leg-length inequality has poor correlation with lumbar scoliosis
It is concluded that before a radiologically observed leg-length inequality be considered as the cause of low-back pain, an erect-posture radiograph of the whole pelvis and lumbar spine is essential, in order to assess an existing pelvic tilt and scoliosis.

The results indicated that, in this group of volunteers, the supine leg length alignment check had clinical validity as a stand-alone test for recurring back pain.
