How to Use This Calculator

Select the Bone location (0 = phalanx, 1 = radius/ulna, 2 = humerus, 3 = clavicle, 4 = tibia, 5 = femur, 6 = pelvis, 7 = vertebra).
Set Fracture severity (0 = hairline/stress to 4 = open/compound) and enter the patient's Age in years.
Indicate Current smoker (0/1) and Diabetes (0/1) — smoking adds ~40% to healing time and doubles nonunion risk.
Select the Fixation method (0 = cast/splint, 1 = ORIF, 2 = IM nail, 3 = external fixation).
Review Estimated healing in weeks, days, and months, plus the Nonunion risk (%) and recommended X-ray follow-up schedule.

How the result changes with Patient age (years)

Bone location: 0=Phalanx, 1=Radius/Ulna, 2=Humerus, 3=Clavicle, 4=Tibia, 5=Femur, 6=Pelvis, 7=Vertebra
Fracture severity: 0=Hairline/stress, 1=Non-displaced, 2=Displaced, 3=Comminuted, 4=Open/compound
Patient age (years): Age in years. Children heal faster; elderly heal slower.
Current smoker?: 0 = No, 1 = Yes. Smoking increases healing time ~40% and doubles nonunion risk.
Diabetes?: 0 = No, 1 = Yes. Diabetes impairs bone healing by ~25%.
Fixation method: 0=Cast/splint, 1=ORIF (plates/screws), 2=IM nail, 3=External fixation

Estimated healing (weeks): Expected time to clinical and radiographic union.
Healing time (days): Healing time converted to days.
Healing time (months): Healing time converted to months.
Weight-bearing start (weeks): Estimated time before protected weight-bearing may begin.
Nonunion risk (%): Estimated risk of nonunion based on patient and fracture factors.
1st follow-up X-ray (week): Recommended timing for first follow-up radiograph.
2nd follow-up X-ray (week): Recommended timing for second follow-up radiograph.
