Abstract
Background: Fractures of the long bones in the lower limbs, such as the femur and tibia, are common injuries that typically result from high-energy trauma. These injuries often require surgical intervention, with techniques like Minimally Invasive Plate Osteosynthesis (MIPO) being favored due to their ability to minimize soft tissue damage while providing stable fixation. However, the success of fracture healing is influenced by various risk factors, including smoking, age, and body mass index (BMI), which can significantly impact the biological and mechanical processes essential for bone repair.Objective: This study aims to assess the impact of various risk factors, including smoking, age, and body mass index (BMI), on the bone healing process in patients who underwent Minimally Invasive Plate Osteosynthesis fixation for extra-articular long bone fractures in the lower limbs.Methods: A cross-sectional analysis was conducted at Basrah Teaching Hospital from June 2010 to June 2012, involving 76 patients aged 20-60 years. Patients with extra-articular comminuted fractures were treated using the Minimally Invasive Plate Osteosynthesis technique. Data on patient demographics, fracture characteristics, surgical details, and postoperative outcomes were collected and analyzed. Statistical significance was determined using appropriate tests, with a p-value of <0.05.Results: The study found that smoking significantly delayed bone healing, with smokers showing slower healing times compared to non-smokers (p=0.0008). Younger patients (<30 years) demonstrated faster healing compared to older patients (p=0.041). Although BMI did not show a statistically significant impact on healing (p=0.716), trends indicated that underweight and normal-weight patients healed faster.Conclusion: Smoking and age are significant factors influencing bone healing in patients undergoing Minimally invasive plate osteosynthesis fixation for lower limb fractures. While BMI did not significantly affect healing outcomes, the findings suggest that lifestyle factors play a crucial role in recovery after fracture fixation.
