Application of pueumatic tourniquet in the operation of lower tibiofibular fracture / 中国骨伤

OBJECTIVE@#To investigate the complications of tourniquet in the clinical application of lower tibiofibular fracture.@*METHODS@#From June 2018 to September 2019, 33 cases of closed lower tibiofibular fractures (AO type 43A) were treated with plates and screws and were divided into two groups according to whether pueumatic tourniquet was used:16 cases in the observation group, 13 males and 3 females, aged 18 to 69 (38.8±17.0) years, the operation time after injury was (6.9±1.7) days, and tourniquet was not used during operation. There were 17 cases in the control group, 13 males and 4 females, aged from 21 to 71 (43.8±12.4) years, the operation time after injury was (6.5±1.0) days, automatic pneumatic tourniquetwas routinely used in the operation. The operation time, blood loss, postoperative swelling, pain and other complications were compared between two groups.@*RESULTS@#Total of 33 patients were followed up for an average of 15 months. There was no significant difference in operation time and blood loss between two groups (@*CONCLUSION@#The fracture of lower tibiofibular segment is superficial and easy to be exposed and fixed during operation. In order to avoid tourniquet complications, it is not recommended to use air bag tourniquet routinely or minimize the application time of tourniquet.

Application of a self-made steel wire guide in the treatment of avulsion fractures of tibial posterior cruciate ligament / 中国骨伤

<p><b>OBJECTIVE</b>To explore the effect of a self-made guiding needle of steel wire in guiding the wire through the tibial tunnel for the treatment of avulsion fractures of tibial posterior cruciate ligament with open reduction and wire fixation.</p><p><b>METHODS</b>From February 2011 to June 2014, a total of 22 patients with avulsion fractures of tibial posterior cruciate ligament underwent surgical treatments were analyzed, including 14 males and 8 females with an average age of 35.6 years old (ranged, 17 to 63 years old). According to Meyers classification, 9 patients were classified as type II, 13 patients were classified as type III. All the patients underwent open reduction and wire fixation with medial knee "L" shape approach. A wire guiding needle was used to guide the wire through the tibial tunnel during operation.</p><p><b>RESULTS</b>With the assistance of wire guidance needles, wires passed through the tibial tunnel rapidly during the operation in all the 22 patients. All the patients were followed up, X-ray imagings 6 months after operation showed the fractures healed well. The average follow-up time in all patients was 6 months (ranged, 6 to 12 months). The averaged Lysholm knee score in 22 knee was 92.7 +/- 3.4. All patients' posterior drawer test were negative.</p><p><b>CONCLUSION</b>Self-made wire guiding needle can simplify the operation procedures in which the wires pass through the tibial tunnel, shorten the operation time, reduce the surgical trauma and complications, and be worthy of clinical application.</p>
