Summary
Accurate lower-limb alignment assessment using X-rays and CT scans is crucial for managing deformities and planning surgeries like total knee arthroplasty. AI may enhance rotational evaluation.
Area of Science:
- Orthopedic surgery
- Medical imaging
- Biomechanical analysis
Background:
- Lower-limb alignment deformities can cause degenerative joint diseases and disabilities.
- Rotational deformities contribute to patellofemoral issues and cartilage degeneration.
- Comprehensive alignment evaluation is key for patient management and surgical planning.
Purpose of the Study:
- To highlight the importance of lower-limb alignment assessment.
- To detail current imaging modalities for evaluating alignment and rotation.
- To suggest potential AI applications in deformity measurement.
Main Methods:
- Full-length standing anteroposterior (AP) radiographs for anatomical and mechanical axis measurement.
- Computed tomography (CT) for precise femoral and tibial rotation assessment.
- Discussion of AI-based automated measurement systems as a future direction.
Main Results:
- Radiographs provide essential data for planning osteotomy and total knee arthroplasty.
- CT offers specialized evaluation of rotational alignment.
- AI presents opportunities for automated and precise rotational measurements.
Conclusions:
- Accurate lower-limb alignment assessment is vital for orthopedic patient care.
- Standard imaging techniques are effective but can be enhanced by AI.
- Improved rotational assessment via AI could refine surgical planning and outcomes.

01:13Radiological Investigation III: Pulmonary Angiogram and PET Scan
86
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...

01:11Anatomical Positions
9.7K
In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

01:16Bones of the Lower Limb: Femur and Patella
2.2K
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...
