Combined osteosynthesis technology in treatment of patients with the consequences of long tubular bone injuries (osteosynthesis technology)

Митрофанов А.И., Чевардин А.Ю.


Purpose. To study the efficiency of combined osteosynthesis technique in treatment of the consequences of long tubular bone injuries.
Materials and Methods. The combination of the techniques of interlocked intramedullary osteosynthesis and external one using the Ilizarov fixator used for treatment of eight patients with shaft defects of long tubular bones. Biomechanical, radiation-related, clinical and statistical methods of studying used. The clinical example of the technology use presented in a female patient with posttraumatic pseudoarthrosis of the left femur with 3-cm shortening.
Results. The patient had no complaints three (3) months after the surgery, as well as she walked without additional supports and with complete weight-bearing of the limb. Joint function was also complete. Computed tomography revealed the absence of bone resorption around the screw interlocking the middle fragment, consolidation of fragments in the zone of docking determined by X-rays, newly formed bone tissue – in the site of lengthening.
Conclusion. The proposed technique of combined osteosynthesis for long tubular bone shaft defects allows to reduce the periods of in-patient treatment, to exclude the device-based fixation of fragments without compromising fixation stability, and to create comfort conditions in patients’ everyday life.
