SSMU scientists have improved the technique of bone tissue restoration

Researchers at the Razumovsky State Medical University in the course of a clinical study have discovered the advantages of using block allografts in the treatment of complex fractures of the humerus.
56 patients with comminuted fractures participated in the study, they were divided into groups depending on the location. Some patients underwent classical surgery using an allograft in the form of cubes, while others had a block graft installed using a special technique with a spike-groove system and locking screws.
To objectively evaluate the results, the doctors performed computed tomography to measure bone stiffness, and also performed ultrasound Dopplerography to determine the quality of blood supply (vascularization index) in the fracture area.
Three months after surgery, the bone density in the fracture area was significantly higher in patients with an established block graft. After 2 months, a similar trend was observed in relation to blood supply.
"We analyzed the results and noted that whole bone blocks perform better. The bone fuses more reliably, the treatment results become more stable, and the recovery process proceeds more confidently," the authors of the study note.
The development of Saratov doctors seems especially relevant today. Orthopedists in all regions note that due to the growing popularity of electric scooters and other means of individual mobility, the number of complex shoulder fractures has increased.
"For young, active people, it is always important to recover quickly from an injury," the researchers explain. "Our method allows us to return to normal life as soon as possible."
At the same time, doctors note that the method continues to improve and requires additional study. Work in this direction is already underway, and in the near future, specialists plan to expand the number of operations using the new technology.
