โ„น๏ธ About this Calculation

This orthopaedics and musculoskeletal clinical calculator evaluates joint replacement outcomes, osteoporotic fracture risk, spinal deformity severity, and physical mobility benchmarks based on AAOS clinical protocols.

Variable Glossary

Input

Biomechanical Data

DXA T-score, Cobb angle degrees, gait velocity (m/s), dynamometer grip strength (kg), or functional survey items.

Parameter

Functional Index

10-year major osteoporotic fracture probability (FRAX %), Oxford joint score (0-48), or spinal curvature classification.

How to Calculate Step-by-Step

1

Step 1

Input patient bone density BMD values, spinal radiograph degrees, or physical test performance numbers.

2

Step 2

Select patient age, gender, and secondary clinical risk factors (prior fracture history, steroid use).

3

Step 3

Review calculated joint function impairment tiers, sarcopenia risk categories, or fracture intervention thresholds.

FAQ

What do Bone Mineral Density T-scores mean?
According to WHO criteria, a T-score of -1.0 or higher is normal, between -1.0 and -2.5 indicates osteopenia, and -2.5 or lower indicates osteoporosis.
How is the Oxford Knee / Hip Score scored?
The Oxford 12-item scales range from 0 to 48 points, where higher scores reflect better joint function and lower pain levels before or after arthroplasty surgery.
Can orthopaedic scoring replace clinical physical examination?
No. Functional scores and risk models supplement orthopedic care. Structural diagnosis and surgical indication require direct physical examination, range-of-motion testing, and radiographic imaging.
