Evaluation of Tobacco Heating System (THS) Compared to Conventional Cigarette Smoking During the Closed Lower Limb (Tibia and Femur) Fracture Healing in Orthopedic Smokers' Patients
University Hospital Tuebingen
150 participants

INTERVENTIONAL
Conditions
Summary
The goal of this clinical trial is to investigate the role of switching from cigarette smoking (CS) to tobacco heat system (THS) on the clinical outcome of closed lower limb (tibia and femur) fractures from smokers' orthopedic patients. Validated and standardized assays, medical state and self-reported outcomes will be evaluated in orthopedic patients' smokers or switch from CS to using THS throughout six months compare to ex-smokers (control).
