“…3 Among demographic factors, diabetes has been shown to significantly lead to fixation failure and increase the risk of a second operation. 20 In the present research, there was no significant difference in BMI between the two groups. Regarding technical errors, incorrect implant placement or insufficient band-wire tension are most commonly involved.…”

Objective To compare a modified two-tension-band (MTTB) technique with the AO tension band in treating patellar fractures. Methods This retrospective study included patients treated with AO tension band (group 1) or MTTB (group 2). Data obtained during serial follow-up evaluations of time to bony union, range of motion (ROM), Hospital for Special Surgery (HSS) score and complication rates, were analysed. Results Fractures healed in all 51 patients included in the study (group 1, n = 28; group 2, n = 23), with no statistically significant between-group difference in time to bony union. Regarding function results, group 2 had better HSS scores at 3 and 6 months postoperatively; however, at 1 year postoperatively, both groups had similar HSS scores and achieved acceptable flexion and ROM. The overall complication rate was significantly lower in group 2, but average costs were higher in group 2 versus group 1. Conclusion MTTB provides secure fixation and improved knee function at 3 and 6 months postoperatively, and has a lower complication rate with early mobilization, compared with the AO tension-band technique.

“…Tibial fractures represent 1.66% of the total cases in adults, and nearly 10% of fracture patients have delayed healing or nonunion, which is the main complication in tibial fracture patients. In recent decades, as many as several million fracture patients are disabled due to poor healing (3,4), so that the patients have decreased productivity and even lose working capacity, thereby increasing social cost (5,6). Therefore, it is extremely important to study the physiological mechanism in the repair of fractures for facilitating fracture healing.…”

Influence of bone marrow-derived mesenchymal stem cells (BMMSCs) on the healing of rabbit tibial fractures and the role of the Janus kinase-signal transducer and activator of transcription (JAK-STAT) signaling pathway in fracture healing were explored. Rabbit BMMSCs were isolated and cultured in vitro, and their purity was determined using flow cytometry. Rabbit fracture models were established, and injected with BMMSCs, BMMSCs + TG101348 or TG101348, with those injected with an equal volume of normal saline as control group, and the repair of fracture ends was evaluated via X-ray examination 3 weeks later. The BMMSCs isolated in vitro grew well, and flow cytometry assay results showed that the positive expression rates of cluster of differentiation (CD)90 and CD105 in cells were 99.21 and 99.56%, respectively, with no CD45 expressed. According to the results of CCK-8 assay, TG101348 lowered the proliferation level of BMMSCs, and the wound healing assay revealed that the migration ability of BMMSCs at 24 and 48 h was substantially weaker than that in control group (P<0.05). After induction of osteogenic differentiation for 3 weeks, alizarin red staining results manifested that osteogenic induction group had notably more calcium nodules than TG101348 group (P<0.05). Compared with those in control group, the protein expression levels of p-JAK2 and p-STAT3 were remarkably raised by osteogenic induction (P<0.05), but the protein expression levels of JAK2, p-JAK2 and p-STAT3 were considerably decreased by TG101348 (P<0.05). It was found through the X-ray examination that the rabbits in control group and those injected with BMMSCs recovered well, and the latter had larger external calluses at fracture ends than the former, while the fracture ends of those injected with TG101348 and BMMSCs + TG101348 were not healed completely. BMMSCs promote healing of rabbit tibial fractures through the JAK-STAT signaling pathway.
