Summary
The Aarhus PAO-database accurately captures patients undergoing periacetabular osteotomy (PAO) for hip dysplasia, showing 94.7% completeness. This validated registry is a reliable resource for hip dysplasia research and quality improvement.
Area of Science:
- Orthopaedic surgery
- Hip dysplasia management
- Clinical database validation
Background:
- Periacetabular osteotomy (PAO) is the standard surgical treatment for hip dysplasia.
- Denmark utilizes the Aarhus PAO-database for tracking PAO procedures.
- Validation of the Aarhus PAO-database against national patient records was necessary.
Purpose of the Study:
- To validate the completeness and accuracy of the Aarhus PAO-database.
- To compare the Aarhus PAO-database with the Danish National Patient Registry (DNPR).
- To assess the reliability of the Aarhus PAO-database for hip dysplasia research.
Main Methods:
- Comparative analysis of PAO procedures between the Aarhus PAO-database and DNPR (2014-2021).
- Random selection of 20 procedures per registry per year for detailed validation.
- Cross-referencing registry data with electronic medical records for accuracy assessment.
Main Results:
- Between 2014-2021, 1144 PAO procedures were in the Aarhus database and 1150 in DNPR.
- Overall registration completeness was 94.7%, with 1116 procedures common to both.
- Validation against medical records confirmed diagnoses and procedures with >95% accuracy.
Conclusions:
- The Aarhus PAO-database demonstrates high completeness and accuracy for PAO procedures in hip dysplasia patients.
- The database is a valid and reliable resource for future research.
- It can be used to monitor and enhance the quality of hip dysplasia treatment.

01:55Bone Structure
Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.
01:40Bone Remodeling
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
01:18Classification of Bones
The bones of the human skeletal system are of varied shapes, sizes, and functions. They can be classified based on their shape and function into four major classes: long bones, short bones, flat bones, and irregular bones. Some classifications include a fifth type, the sesamoid bones, as a separate class, whereas others categorize them under short bones.

01:27Fractures: Bone Repair
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

01:29Bone Disorders
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:19Bones of the Upper Limb: Humerus
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
