Toe-walking
For discrepancies less than 3% in the long extremity, what was NOT associated?
Pelvic obliquity
What was found to have no correlation with the length discrepancies?
Pelvic obliquity
What is considered a significant limb length discrepancy?
3mm - 22mm
What is one of the primary symptoms associated with limb length discrepancy?
Sacroiliac joint pain on the long limb
What is the most common compensation for a functional limb length discrepancy with excessive STJ pronation?
Pronation of the foot to shorten the limb
In clinical examination, what is the variation to the direct measurement from ASIS to medial malleolus when joint contracture and bone torsion need to be accounted for?
ASIS to lateral malleolus
Why is it important to add a third reference point for accuracy in clinical examination when checking for limb length discrepancy?
To account for pelvic height difference
What is the most common compensation for pelvic rotation with limb length discrepancy?
Functional scoliosis
In the context of limb length discrepancy treatment, what warrants the need for corrective intervention?
A significant limb length discrepancy
What type of lift is typically used when the limb length discrepancy is 1 cm or more?
Full length lift
What is used to evaluate the gait of children with limb-length discrepancy in the provided text?
Radiographic evaluation
If a limb-length discrepancy is functional due to increased pronation, what is the recommended corrective approach?
Orthosis for correcting pronation
What percentage of discrepancy was associated with more mechanical work being performed by the long extremity?
5.5%
What strategy was NOT associated with discrepancies of less than 3% of the length of the long extremity?
Pelvic rotation
What was the average range in age of the boys and girls mentioned in the text?
8 to 17 years
Which of the following deformities was NOT found in the lower extremities of the patients?
Medial deformity
What discrepancy percentage was NOT correlated with any dependent kinematic or kinetic variables, including pelvic obliquity?
3%
Which compensatory strategy was manifested when a discrepancy of 5.5% or more was observed clinically?
Toe-walking
What is the main difference between structural limb length discrepancy (LLD) and functional LLD?
Structural LLD results from polio or physeal damage, while functional LLD is associated with joint contracture.
In the context of limb length discrepancy, what is the purpose of adding a third reference point for accuracy in clinical examination?
To accurately measure joint contracture and bone torsion.
What symptom is specifically associated with sacroiliac joint pain due to pelvic tilt in limb length discrepancy?
Foot pathology with excessive pronation.
Why does a fixed scoliosis not reduce with non-weight bearing (NWB) when present with limb length discrepancy?
As it is the primary pathology with limb length discrepancy compensating for it.
What is the most appropriate course of treatment for limb length discrepancy if induced by excessive supination?
Use orthotics to correct pronation only.
What is the key factor that determines whether scoliosis is a primary pathology when present with limb length discrepancy?
Whether the scoliosis is functional or fixed.
What is the significance of posterior pelvic rotation in the compensation of limb length discrepancy?
Posterior pelvic rotation occurs with pronation on the long limb.
When should a full-length lift be used in treating limb length discrepancy?
If the discrepancy is 1 cm or more.
What is the purpose of using orthotics with a lift when treating a combined etiology of limb length discrepancy?
To address both functional and structural causes simultaneously.
What is the purpose of an EBM evaluation of gait in children with limb-length discrepancy mentioned in the provided text?
To evaluate the body's attempt to correct limb-length discrepancies.
