Leg Length Inequality

Inequalities Leg Length


Presentation

  • Leg-length inequality (difference or 1 cm) was present in 37 subjects with GTPS and in 163 subjects without GTPS (P 0.86).[ncbi.nlm.nih.gov]
  • Abstract We present the results of 38 children with leg inequality treated by circumferential periosteal release. Leg-length discrepancy was expressed as a percentage of the longer limb.[ncbi.nlm.nih.gov]
  • Presented at NACOB 98: North American Congress on Biomechanics. August 1998.[veterans.gc.ca]
  • Presentation An athlete who presents with an Anatomical LLI should first undergo a basic Leg Length Evaluation. An athlete with an Anatomical LLI, will present with one leg shorter than the other, and a completely neutral pelvis.[maximumtrainingsolutions.com]
  • The aim of the present study was to investigate a possible association between leg length inequality (LLI) and unilateral posterior crossbite. A survey was carried out in young adolescents recruited from three schools.[ncbi.nlm.nih.gov]
Malocclusion
  • Section of Orthodontics and Clinical Gnathology, University of Naples 'Federico II', Via Pansini 5, I-80131 Naples, Italy. michelot@unina.it Abstract It has been suggested that malocclusions may influence whole body posture, including leg length, but[ncbi.nlm.nih.gov]
Low Back Pain
  • The degree of low back pain was significantly reduced after the operation.[ncbi.nlm.nih.gov]
  • Degeneration of the lumbar spine was the only factor that correlated well with low-back pain.[ncbi.nlm.nih.gov]
  • Abstract Leg-length inequality and its hypothetical consequences, pelvic tilt and lumbar scoliosis, were measured in 100 young or middle-aged adults suffering from chronic low-back pain.[ncbi.nlm.nih.gov]
  • Supine measurements should not be used to estimate standing leg length discrepancy in new low back pain patients but perhaps can be used in other clinically meaningful ways.[ncbi.nlm.nih.gov]
  • Abstract Differences in the right and left lumbosacral facetal "joint angles' are compared in non-acute low back pain patients with a leg length discrepancy of greater than 9 mm and a control group with a 0-3 mm leg length discrepancy.[ncbi.nlm.nih.gov]
Hip Pain
  • We assessed the influence of leg lengthening and shortening on walking capacity, hip pain, limping and patient satisfaction at 2-year follow-up.[ncbi.nlm.nih.gov]
  • Leg length inequality has been linked with lower extremity stress fractures, low back pain, hip pain and vertebral disk problems of runners.[ncbi.nlm.nih.gov]
  • METHODS: A cross-sectional analysis of greater trochanteric tenderness to palpation was performed in subjects with complaints of hip pain and no signs of hip osteoarthritis or generalized myofascial tenderness.[ncbi.nlm.nih.gov]
  • It is a puzzle piece that we look for when evaluating a patient with low back pain or hip pain to see if it could be an underlying factor.[tulsaspineandrehab.com]
  • The combined clinical research and surgical experience of the editors and contributors present all aspects of this procedure, including neurologic injury, failure mechanisms, evaluating the painful hip, pain syndromes, approaches to the femur and acetabulum[books.google.com]
Spine Pain
  • Pain and fatigue from the longer leg’s Quadriceps and hamstring muscles (flexed knee syndrome). Patients flex their knee during gait to maintain level pelvis.[physio-pedia.com]
  • . • Limb-length inequality of more than 2.5 cm has traditionally been considered significant, with an increased likelihood of knee, hip, and lumbar spine pain; 4. • The short leg gait is awkward • increases energy expenditure because of the excessive[slideshare.net]
Ankle Pain
  • As a result of having a leg length inequality, patients may experience other conditions such as low back pain and hip pain (it’s possible that knee and ankle pain can occur as well).[tulsaspineandrehab.com]
Impulsivity
  • The shorter leg is likely to sustain increased impact force of the foot during gait thus transmitting a greater impulse up the ipsilateral leg. LLI is easily treatable and therefore could be a potentially modifiable risk factor for disease.[acrabstracts.org]
Abnormal Gait
  • The magnitude of leg-length inequality closely correlated with awareness of the inequality, abnormal gait, use of ambulatory assistive devices, the need for a shoe lift, prior leg-length inequality, and revision THA.[ncbi.nlm.nih.gov]
  • PURPOSE: Leg length inequalities (LLIs) can result in an increased energy consumption, abnormal gait or osteoarthritis of the hip.[ncbi.nlm.nih.gov]
  • LLD may cause generalised patient dissatisfaction as well as an abnormal gait, back pain and sciatica [2 – 6]. A small true LLD is common, with published mean discrepancies ranging from 1 to 15.9mm [7 – 9; 10 – 15].[ispub.com]
  • Abnormal gait, pain, neurological disturbance and patient dissatisfaction have all been described as a result of leg length inequality after THR.[biblioteca.posgraduacaoredentor.com.br]
Neglect
  • Don’t let your practice be a casualty, getting slapped with a mandatory 50,000 minimum fine for a breach of HIPAA privacy rules or a “willful” neglect violation.[chirotexas.org]

Workup

  • This is called leg length alignment asymmetry (LLAA) and can be seen while lying down. [1] Diagnosis and workup [ edit ] X-rays for leg length measurement.[en.wikipedia.org]
  • The standard workup for LLD is a thorough physical examination, including watching the child walk and run as well as a 3-joint standing x-ray or an x-ray scanogram to determine the actual length of the bones of the legs.[columbiadoctors.org]

Treatment

  • Abstract The principles of treatment of congenital leg length inequality include three strategies: joint stabilization, axis correction, and limb length equalization.[ncbi.nlm.nih.gov]
  • A prediction of the ultimate leg length inequality at skeletal maturity will be needed to determine treatment. Our guidelines for treatment of leg length inequality are as follows:[ncbi.nlm.nih.gov]
  • A mean clinical LLI of 1.7 cm was the treatment outcome for the entire group. Valgus deformity of 7 , 10 and 13 occurred in three patients. CONCLUSIONS: 1.[ncbi.nlm.nih.gov]
  • The subjects then entered a treatment room where they were randomly given no treatment, cervical adjusting, or gluteal massage. This process continued for 5 cycles.[ncbi.nlm.nih.gov]
  • Methods of treatment and prevention are discussed.[ncbi.nlm.nih.gov]

  • Background and Etiology There are 2 basic causes of an Anatomical Leg Length Descrepency; Congenital Congenital Anatomical LLI occurs because an athlete genetically grows one leg longer than the other.[maximumtrainingsolutions.com]
  • The etiology of idiopathic scoliosis has been studied in many aspects such as genetic factors, skeletal muscle abnormalities, neurological mechanisms, and biomechanical factors, while the common causes of secondary or functional scoliosis are leg length[clinicaltrials.gov]
