Our objective was to conduct a systematic review and meta-analysis, comparing differences in clinical outcomes between either autologous or synthetic bone grafts in the operative management of tibial plateau fractures: a traumatic pattern of injury, associated with poor long-term functional prognosis. A structured search of MEDLINE, EMBASE, The Bone & Joint and CENTRAL databases from inception until 07/28/2021 was performed. Randomised, controlled, clinical trials that compared autologous and synthetic bone grafts in tibial plateau fractures were included. Preclinical studies, clinical studies in paediatric patients, pathological fractures, fracture non-union or chondral defects were excluded. Outcome data was assessed using the Risk of Bias 2 (ROB2) framework and synthesised in random-effect meta-analysis. Preferred Reported Items for Systematic Review and Meta-Analysis guidance was followed throughout. Six comparable studies involving 352 patients were identified from 3,078 records. Following ROB2 assessment, five studies (337 patients) were eligible for meta-analysis. Within these studies, more complex tibia plateau fracture patterns (Schatzker IV-VI) were predominant. Primary outcomes showed non-significant reductions in articular depression at immediate postoperative (mean difference −0.45mm, p=0.25, 95% confidence interval (95%CI): −1.21-0.31mm, I. 2. =0%) and long-term (>6 months, standard mean difference −0.56, p=0.09, 95%CI: −1.20-0.08, I. 2. =73%) follow-up in synthetic bone grafts. Secondary outcomes included mechanical alignment, limb functionality, defect site pain, occurrence of surgical site infections, secondary surgery, perioperative blood loss, and duration of surgery. Blood loss was lower (90.08ml, p<0.001, 95%CI: 41.49-138.67ml, I. 2. =0%) and surgery was shorter (16.17minutes, p=0.04, 95%CI: 0.39-31.94minutes, I. 2. =63%) in synthetic treatment groups. All other secondary measures were statistically comparable. Our findings supersede previous literature, demonstrating that synthetic bone grafts are non-inferior to autologous bone grafts, despite their perceived disadvantages (e.g. being biologically inert). In conclusion, surgeons should consider synthetic bone grafts when optimising peri-operative patient morbidity, particularly in complex tibial plateau fractures, where this work is most applicable

Abstract. Objectives. to evaluate the efficacy and safety of topically applied tranexamic acid (TXA) in thoracolumbar spinal tuberculosis surgery, posterior approach. Methods. Thoracolumbar spine tuberculosis patients who requiring debridement, pedicle screw fixation and fusion surgery were divided into two groups. In the TXA group (n=50), the wound surface was soaked with TXA (1 g in 100 mL saline solution) for 3 minutes after exposure, after decompression, and before wound closure, and in the control group (n=116) using only saline. Intraoperative blood loss, drain volume 48 hours after surgery, amount of blood transfusion, transfusion rate, the haemoglobin, haematocrit after the surgery, the difference between them before and after the surgery, incision infection and the incidence of deep vein thrombosis between the two groups. Results. EBL for the control group was 783.33±332.71 mL and for intervention group 410.57±189.72 mL (p<0.001). The operative time for control group was 3.24±0.38 hours and for intervention group 2.99±0.79 hours (p<0.695). Hemovac drainage on days1 and 2 for control group was 167.10±53.83mL and 99.33±37.5 mL, respectively, and for intervention group 107.03±44.37mL and 53.38±21.99mL, respectively (p<0.001). The length of stay was significantly shorter in the intervention group (4.8±1.1 days) compared to control group (7.0±2.3 days). There was bo different in incision side infection and DVT. Conclusions. Topical TXA is a viable, cost-effective method of decreasing perioperative blood loss in major spine surgery with fewer overall complications than other methods. Further studies are required to find the ideal dosage and timing

Introduction. This study aimed to compare MIPO and IMNr in the treatment of supracondylar femur fracture following TKA in respect of fracture healing, complications and functional results. Materials and Methods. A retrospective analysis was made of 32 supracondylar femur fractures classified according to the Rorabeck classification, comprising 20 cases treated with MIPO and 12 with IMNr. The two techniques were compared in respect of ROM, KSS, SF-12 scores, intraoperative blood loss, surgery time, and radiological examination findings. Results. No significant difference was determined between the two groups in respect of age, gender and fracture type, or in the median time to union (MIPO 4.3 months, IMNr 4.2 mths) (p >0.05). In the MIPO group, 2 patients had delayed union, so revision surgery was applied. The mean postoperative ROM was comparable between IMNr and MIPO (86.2 °vs 86 °, p > 0.05). The mean Knee Society Score (KSS) and SF-12 score did not differ between the IMN and MIPO groups. (p>0.05). Reduction quality in the sagittal plane was better in the MIPO group and no difference was determined in coronal alignment. Greater shortening of the lower extremity was seen in the IMNr group than in the MIPO group. (20.3 vs 9.3mm, p<0.05). Perioperative blood loss was greater (2 units vs.1.2 units) and mean operating time was longerin the MIPO group. (126.5 min vs 102.2 min, p<0.05). Conclusion. In patients with good bone stock, supracondylar femur fracture following TKA can be treated successfully with IMN or MIPO. IMN has the advantage of less blood loss and a shorter operating time. Reduction quality may be improved with the MIPO technique. Both surgery techniques can be successfully used by orthopaedic surgeons taking a case-by-case approach
