| Summary: | Background. Due to the technological progress in traumatology, there are more opportunities to apply MIPO (minimally invasive plate osteosynthesis) techniques for treating pelvic ring injuries. However, such problems as implant malposition due to complicated intraoperative visualization and the risks of postoperative complications remain relevant.
The aim of the study — to evaluate the effectiveness of 3D printing technology during preoperative planning and intraoperative navigation in minimally invasive surgery for pelvic injuries.
Methods. This study presents the experience of surgical treatment of 53 patients with various pelvic injuries using 3D technologies. The patients are divided into 3 groups depending on the location of injury: Group 1 — with isolated posterior pelvic ring injuries; Group 2 — with anterior and posterior pelvic ring injuries; Group 3 — with combined pelvic and acetabular injuries. The proposed technique involves the use of software to generate a digital model, 3D printing, conducting preoperative elaborate preparation on the plastic model, its sterilization and application as a navigation device during the operation for accurate positioning of metal fixators in intended directions.
Results. Five patients have dropped out of the study (3 foreigners, 1 patient was transferred to the psychosomatic department of related medical facility, 1 patient died as a result of pulmonary embolism at 1.5 months post-op). At the time of writing, 48 patients remained in the study: radiographic signs of fracture union were noted in 43 (90%) cases, in the remaining 5 (10%) cases, the follow-up period was less than the average fusion period (3 months). Among 43 patients with confirmed fracture union, the functional result 8 months after surgery according to the Majeed scale in Group 1 was 92 points, in Group 2 — 89 points, in Group 3 — 74 points. In 2 patients, after fracture union, screw migration associated with osteoporotic changes was observed in the posterior pelvis. No other complications were noted.
Conclusions. Accurate reduction and stable minimally invasive fixation of pelvic ring injuries, combined with 3D technologies, are of great importance for early rehabilitation of patients, especially given the morpho-anatomical variability of the pelvic bones. This approach reduces the incidence of implant malposition and helps to minimize long-term consequences of the injury. The conducted retrospective study demonstrated the relevance, safety, and reliability of 3D printing technology in enhancing the diagnosis and treatment of patients with pelvic bone injuries. |
