Summary
Visual inspection alone is unreliable for detecting lower limb malalignments. Accurate diagnosis requires physical examination and radiographical assessments, as visual cues do not provide clinically relevant information for alignment issues.
Area of Science:
- Orthopedics
- Radiology
- Biomechanical analysis
Background:
- Lower limb malalignment assessment is crucial in clinical practice.
- Visual inspection is a common but potentially unreliable method for evaluating alignment.
Purpose of the Study:
- To evaluate the reliability of visual inspection in detecting lower limb malalignments.
- To determine if visual assessment of leg alignment is clinically relevant without additional diagnostic tools.
Main Methods:
- 50 patients underwent whole leg radiography (WLR) and digital lower limb photography.
- Four raters visually assessed limb alignment from photographs, categorizing it into valgus/varus degrees.
- Visual ratings were correlated with hip knee angle (HKA) measured on WLRs using Spearman's rho.
Main Results:
- A moderate correlation (Spearman's rho = 0.478) was found between visual assessment and measured HKA.
- Women showed a significantly higher odds ratio (3.7) for incorrect visual assessment.
- Higher HKA values also increased the odds ratio for erroneous visual assessment (1.4).
Conclusions:
- Visual inspection of lower limb alignment lacks clinical relevance for diagnosing malalignments.
- Reliance solely on visual inspection is insufficient for accurate lower limb alignment assessment.
- Physical examination tests and radiographical assessments are recommended for reliable diagnosis.

The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
