Tibia Fracture

The goals of this clinical trial are: to test the feasibility of identifying patients and getting patients the floor pedal bikes, to test how well floor pedal bikes help patients with lower body injuries heal, and to test methods of patient self-reported logs for home pedal bike use. Participants will be given a floor pedal bike at first post-operative appointment where weightbearing restrictions are lifted (weight-bearing as tolerated) along with instructions on utilization. Participants will be asked to complete patient reported outcome measure surveys at each follow-up visit.

This project consists of a prospective case design. Study candidates will include all patients ages 18 and over who were evaluated at UCSD and found to have a critical-sized humerus, femur, or tibia segmental defect that would be fixed through surgery. Patients who consent to study participation will receive the TRUMATCH Graft Cage for their long bone segmental defect repair. Data on healing rates, complication rates, re-operation rates, time to return to normal activity, and pain levels will be collected for each participation. After 3 years of data collection, we will analyze this data to provide further insight on the utility of the TRUMATCH Graft Cage. Given the significant difficulty with repairing segmental long bone defects, it is imperative to evaluate novel systems to appropriately manage these injuries.

Aim of our study is to compare immediate full weight-bearing and partial weight-bearing for 6 weeks after a tibial shaft fracture treated with intramedullary nailing. Co-primary outcome is return to work and physical component scale in the SF-36 questionnaire.

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).
