However the stability provided by the titanium IMN may not be adequate, there by influencing the union rate. We aimed to compare the results of both IMN systems via prospective clinical study and biomechanical testing using RSA. Biomechanical study This study was done in an experimental set-up which consisted of a physically simulated femoral shaft fractures models fixed with a stainless steel Russell Taylor or Titanium Trigen IM nailing system.
Two common fracture configurations with stimulated weight bearing conditions were used and the axis of fragment movements recorded. Clinical study The data on two groups of patients were collected as part of a prospective cohort study. Details of the implant, such as size of nail, cross screw lengths, screw thickness, etc.
Patients were followed up for a minimum o However, there are still complications following nail surgery including non-union, delayed union, and fracture of the bone or the implant. Reducing nail stiffness while still maintaining sufficient stability seems to be the ideal solution to overcome the abovementioned complications. The mechanical performance of this new implant in terms of fracture stability and load sharing was assessed using a comprehensive non-linear finite element model.
The proposed model considers several mechanical factors in nine fracture configurations at immediately post-operative, and in the healed bone stages. Results: The post-operative results showed that the hybrid composite nail increases the average normal force at the fracture site by Background: Intertrochanteric hip fractures rank in the top 10 of all impairments worldwide in terms of loss in disability-adjusted years for people aged older than 60 years.
The type of surgery is usually carried out with dynamic hip screw DHS devices or cephalomedullary nails. Objective: The Design of Improved Intertrochanteric Fracture Treatment DRIFT study's main objective is to provide intertrochanteric fracture treatment expertise, requirements and specifications, clinical relevance, and validation to improve treatment outcomes by developing a universal algorithm for designing patient-and fracture-oriented treatment.
