Background. Growing number of patients with pelvic fractures is associated with evolution of high-speed transport, high-rise construction and industrial production. The optimal surgical procedure for pubic rami fractures must ensure a stable fixation and simultaneously minimize the risk of postoperative complications. Our aim was to evaluate the efficiency of a new technique for pubic bones fixation by a titanium nail in patients with pelvic fractures.Material and Methods. The authors present the experience on treatment of 18 patients who underwent 25 surgeries for internal fixation of pubic rami fractures by a designed solid titanium nail. Mean age of patients was 40.16±10.35 years. Proposed surgical method provides for mandatory use of image intensifier during all stages of the procedure. With patient in a supine position the authors performed internal fixation of pubic bones by a retrograde nail inserted using a navigating handle through a skin incision of1 cm in the area of symphysis. After complete insertion into the bone the nail was interlocked proximally by two3.5 mm cortex screws through an additional skin incision of1.0 cm using a navigating handle and guiding sleeves. All pelvic ring fractures were classified according to AO/OTA classification and pubic fractures by Nakatani classification. Functional outcome was evaluated by Majeed score.Results. Bilateral fractures were diagnosed in 7 (38.8%) patients (floating pubic symphysis). 13 (72.2%) patients featured polytrauma with average ISS score of 25.1±7.8. 2 (11,1%) patients were diagnosed with open pelvic fractures, 3 (16.6%) patients had a concomitant acetabular fracture. The authors performed epicystostomy in two (11.1%) patients and laparotomy bringing out the drainages in 5 (27,8%) patients. Mean follow up was 7.8±6.2 months. Stable fixation was obtained in all patients. By the moment of the present publication x-ray healing of pubic bones was observed in 16 (64%) cases, in remaining 9 (36%) cases the follow up period was less than mean healing period (2 months). In 11 (68.8%) patients the functional outcome averaged 91±3.9 by Majeed score 6 months postoperatively, in 8 (50%) patients – 93.8±2.9 by Majeed score 12 months postoperatively and more. No complications like skin necrosis, secondary fragments displacement or infection were not observed.Conclusion. Preliminary results demonstrated the absence of wound infection and reliable fragments fixation. This technique can be applied in patients with stomas and drainages upon the anterior abdominal wall which extends the indication range for surgical treatment of anterior pelvic ring. High fixation properties of proposed nailing create conditions for early mobilization of the patients and for conducting the exercise therapy.

Background. In acetabular fractures, the correct choice of the surgical approach is mandatory to achieve accurate reduction and to avoid complications. Anterior approaches include the ilioinguinal, the Stoppa, the iliofemoral and the pararectal exposures. The ilioinguinal and the Stoppa approaches are the most ones nowadays. The purpose of the study was to compare the efficacy of modified Stoppa and ilioinguinal approach in the management of acetabular fractures in terms of quality of reduction achieved, complication rates, functional outcomes, operative time, intraoperative blood loss, view angle of the surgical wound, the applicability of the forceps. Materials and Methods. The study enrolled 53 adult patients. We evaluated 53 cases of treatment of patients underwent acetabular fractures osteosynthesis. The patients were divided into two groups. We used the Letournel approach in group 1 (n = 27), the Stoppa/iliac approach — in group 2 (n = 26). The group 2 was split into two subgroups: in subgroup 2A, osteotomy of the anterior superior spine was performed (n = 13), in subgroup 2B, we did not perform it (n = 13). The following parameters were compared: the quality of reposition of fragments, operation time, intraoperative blood loss, damage to neural structures, viewing angle, and ease of use of pelvic instruments for reduction. The functional outcome was assessed by the Majeed scale. Results. Comparison of the two approaches showed that the indices of reduction of fragments, total blood loss and operation time did not differ significantly and were not statistically significant (p0.05). However, there were more neurological complications in group 1, but they did not affect the treatment outcome. The angle of the sector of view during the operation with osteotomy of the anterior superior spine of the pelvic wing is about 90°, which contributes to a more efficient use of repositioning instruments. The functional results of treatment were the same in both groups in 12 months after surgery. Conclusion. The Letournel and the Stoppa/iliac approach are equivalent in terms of the degree of reduction, operation time and blood loss during the operation. Application the Stoppa/iliac approach helps to avoid iatrogenic meralgia paresthetica unlike Letournel approach. The Stoppa/iliac approach and osteotomy of the anterior superior spine provides better visualization and provides a greater degree of freedom for the surgeon during manipulation tools for reposition.

Background.Vascular bone graft transposition is the one of most effective method of nonunion fracture and bone defect treatment. However, the use of this technique is associated with some difficulties. One is the adjustment of recipient bed size and the graft. The other is the difficulty to reconstruct the alignment and length of bone. A promising method of preparing for the vascular bone graft transposition is virtual three-dimensional planning based on computed tomography data and three-dimensional printing templates.The aimwas to summarize our experience in the treatment of bone nonunion and defects with vascular bone autografts using tree-dimensional virtual planning and printing.Material and methods.We analyzed the treatment process and outcomes of 4 patients with limb bone nonunion and 6 patients with bone defects. In all cases, we used vascular bone grafts. Internal fixation of grafts was used in 7 cases, external fixation was used in 3 cases. At preparation stage in 4 cases, we used tree-dimensional virtual surgery planning and printing templates.Results.One case was diagnosed with bone graft necrosis caused by venous thrombosis. Consolidation was achieved in all patients; a late consolidation was observed in 2 cases. Hematoma in donor area was seen in 2 patients. When using three-dimensional virtual planning and tree-dimensional printing templates, the operation time was decreased by 1 hour 5 minutes. We identified two cases of poor reposition in the group without virtual planning. No poor reposition was observed in the cases where tree-dimensional planning was used.Conclusion.Vascularized bone grafts provide an effective method to treat bone defects and nonunion. But the planning of graft and recipient site sizes is associated with certain difficulties. Our preliminary results have shown that virtual three-dimensional planning and printing allow improving the precision of the surgical procedure and decreasing operative time.
