[Accuracy and clinical efficacy of robot-assisted transiliac-transsacral screw placement for posterior pelvic ring fractures].

OBJECTIVE: To explore accuracy and clinical effect of robot-assisted implantation of sacroiliac penetrating screw in orthopedic surgery for posterior pelvic ring fracture. METHODS: The clinical data of 24 patients with posterior pelvic ring fracture treated with robot-assisted sacroiliac penetration screws from August 2022 to August 2023 were retrospectively analyzed, including 10 males and 14 females; aged from 21 to 73 years old with an average of (49.29±14.48) years old;according to Tile pelvic fractures, 13 patients were type B and 11 were type C. The effect of screw placement was evaluated according to Gras criteria based on postoperative CT scan results. At the final follow-up, fracture healing was evaluated according to Matta score, and functional recovery was evaluated by Majeed score. RESULTS: All patients were followed up for 3 to 13 months with an average of (6.00±3.28) months. Totally 36 sacroiliac penetrating screws, 18 S1 penetrating screws, 18 S2 penetrating screws were inserted, a total of 29 were excellent and 7 good according to Gras standard. Screw adjustment times was 0.00 (0.00, 0.75) times. At the final follow-up, Matta score was excellent in 18 patients, 5 good and 1 moderate, and the maximum displacement distance was 2.55 (0.00, 5.65) mm. Majeed score was 84.37±8.38, 15 patients were excellent, 7 good and 2 moderate. CONCLUSION: Robot could accurately and safely assist in the placement of sacroiliac joint screws for the treatment of posterior pelvic ring fractures, and promote postoperative functional recovery of patients.

[Analysis of the effects of different medicines on hypercoagulability state variations of femoral shaft fracture and after its operation].

OBJECTIVE: To explore the role of Tong Mai Tang & Lornoxicam on the serum concentrations of tumor necrosis factor alpha (TNF-alpha), interleukin (IL-6) , D-dipolymer( D-Di), Platelet count (PLC) in treatment of femoral shaft fracture among period surgery time. METHODS: We selected 120 cases of traumatic femoral shaft fracture patients according to the inclusion criteria and exclusion criteria, which were randomized dividend into four groups (I, II, III, IV respectively) of the same size based on the random number table method of 30 patients each. Therapeutic methods of four groups following as: Group I, Tpanax Notoginseng Pills PO; Group II, Tpanax Notoginseng Pills PO, Lornoxicam For Injection, 8 mg IM; Group III, Tpanax Notoginseng Pills PO, Tong Mai Decoctions 200 mL PO; Group IV, Tpanax Notoginseng Pills PO, Lornoxicam For Injection 8 mg IM, Tong Mai Decoctions 200 mL PO. The above medications were administered to the four groups after admission to hospital the next day. Peripheral blood samples were taken for immune determination of pro-inflammatory cytokines of TNF-alpha, IL-6, D-Di, PLC in blood serum on the 2nd and 6th day before operation and on the 8th and 13th day after operation in the morning. And all patients received liver and kidney function examination 2nd and 13th day after admission. Analysis of variance and least significant difference-test were done with the help of SPSS 17.0 statistic software. RESULTS: The difference among four groups in TNF-alpha and IL-6 were significant (P < 0.05). And there were also significant statistic difference between group II/III/IV and group I group (P < 0.05). But the difference between group II and group III was insignificant (P > 0.05). However, the group contrast result between group IV and group II/III had statistics difference (P < 0.05). The difference in D-Di PLC at 6th day and 8th day were significant (P < 0.05). The group comparisons in group I/II/IV were also significant. There were non-statistics significance in group II compared 6th day/8th day with 2nd day (P > 0.05). The comparison between the 13th day with the first three time sections had statistics significance. And there were statistics significance at the 13th day between group IV and group II (P < 0.05). CONCLUSION: The serum concentrations of TNF-alpha, IL-6, D-Di and PLC level were significantly increased in peroperative period, These results seem to indicate that the Tong Mai Decoctions & Lornoxicam may play an important role in inhibiting the release of TNF-alpha, IL-6, D-Di and PLC into the blood stream and decreasing the incunabula complication at early traumatic stage. The Tong Mai Decoctions & Lornoxicam was the worth promoting screened China and the West union medication combination.

[Effects of Tongmai decoction on the perioperative changes of plasma TNF-alpha and IL-6 in patients with femoral fractures].

OBJECTIVE: To explore the effects of Tongmai decoction on the perioperative changes of serum concentrations of tumor necrosis factor alpha (TNF-alpha) and interleukin (IL)-6 in patients with femoral fractures, and conform the effectiveness of Tongmai decoction on inflammatory factors in patients with femoral fractures, providing the theoretical evidence for the clinical use of Tongmai decoction. METHODS: From October 2007 to May 2009, 60 patients with closed traumatic femoral fractures were selected according to the inclusion criterias and exclusion criterias. All the patients were randomly divided into three groups (group A, group B and group C). Twenty patients in group A (Tpanax Notoginseng pill group), 13 patients were male and 7 patients were female; ranging in age from 20 to 45 years, averaged 32.0 years; the disease course ranged from 2.0 to 26.0 h, with an average of 9.5 h. Twenty patients in group B (Tpanax Notoginseng pills and Lornoxicam injection group),12 patients were male and 8 patients were female; ranging in age from 23 to 42 years, averaged 31.0 years; the disease course ranged from 3.5 to 25.0 h, with an average of 13.6 h. Twenty patients in group C (Tpanax Notoginseng pill, Lornoxicam injection and Tongmai decoction group), 14 patients were male and 6 patients were female; ranging in age from 21 to 44 years, averaged 31.5 years; the disease course ranged from 4.6 to 29.0 h, with an average of 13.3 h. Among all the patients, 42 patients with fractures were fixed with femoral intramedullary nailing, and other 18 patients with femoral locking plate fixation. The patients in group A took Tpanax Notoginseng pills orally, 4 g each time and twice daily; the patients in group B took Tpanax Notoginseng pills orally as group A, and at the same time received intramuscular injection of Lornoxicam, 8 mg each time and once daily; the patients in group C took Tpanax Notoginseng pills orally and received intramuscular injection of Lornoxicam as group B, and at the same time took Tongmai decoction (R ) orally, 200 ml each time and twice daily. The above medications were administered to the three groups on the second day after admission to hospital. Peripheral blood samples were taken for determination of pro-inflammatory cytokines of TNF-alpha and IL-6 in blood serum on the 2nd and 6th days before operation and on the 8th and 13th days after operation. And all the patients were evaluated liver and kidney function at the 2nd and 7th days after admission. Analysis of variance and least significant difference-test were done with the help of SPSS 17.0 statistic software. RESULTS: The differences among three groups of TNF-alpha and IL-6 in blood serum at the 2nd day after admission and 2 days after operation had no statistical significance (P > 0.05). The TNF-alpha and IL-6 levels among 3 groups had statistical differences at the 7th day after admission and at the 7th day after operation (P < 0.05, P < 0.01). There were significant differences of TNF-alpha and IL-6 levels between the 7th day after admission and the 2nd day after admission, the 7th day after operation and the 2nd day after admission (P < 0.01). There were also significant differences of TNF-alpha and IL-6 levels between group C compared with group A and B at the 7th day after admission and the 7th day after operation(P < 0.05, P < 0.01). CONCLUSION: The serum concentrations of TNF-alpha and IL-6 level significantly increased in perioperative period. The results indicate that the Tongmai decoction may play an important role in inhibiting the release of TNF-alpha and IL-6 into the blood stream and decreasing the incunabula complication at early traumatic stage.
