Objective To introduce the operation method of a rotational support plate through a traditional anterolateral approach for posterolateral tibial plateau fractures and analyze the postoperative outcome.Methods From May 2016 to September 2017,10 patients with posterolateral tibial plateau fractures who underwent surgery with the rotational support plate were retrospectively analyzed.There were 6 males and 4 females,aged from 23-66 years (average,46.2 years).The causes of the fractures included traffic accident in 4 cases,fall from height in 5 cases and falling injury in 1 case.According to AO-OTA classification,there were 1 case of 41-B2,8 cases of 41-B3 and 1 case of 41-C3.According to Schatzker classification,there were 6 cases of type Ⅱ,1 was of type Ⅲ,2 were of type Ⅴ,and 1 was of type Ⅵ.Four cases suffered multiple fractures.One patient suffered pelvic fracture,ipsilateral femoral shaft and medial malleolus fracture;One patient suffered ipsilateral tibiofibular fracture;1 patient suffered ipsilateral fibular head and medial femoral epicondyle fracture;One patient suffered ipsilateral fibular head fracture.Fracture healing time,complications,knee range of motion,Hospital for Special Surgery (HSS) knee score were recorded to evaluate postoperative outcomes.Results All 10 patients were followed up for 15.25 months (range,12-27 months).The bony union time ranged from 3.0-4.5 months (average,3.2 months).The range of motion of the knee joint was 105°-161.4° (average,139.9°).According to the HSS system,the score was 64-98 (average,88),including 8 of excellent and 2 of fair.No skin necrosis,incision infections,or fixation failure occurred during follow-up.Conclusion Fixation of posterolateral tibial plateau fracture was successfully achieved using the newly designed plate through a traditional anterolateral approach.It has many advantages such as reliable fixation,satisfying recovery,simplicity of operator,and small tissue damage.
在中国现代戏剧史上,没有哪位作家能像丁西林(1893—1974)一样,作品极少却又如此频繁地被人提起.即使在 1939 年后便中断了写作,①他仍然是戏剧技巧最为精湛的中国现代喜剧作家,无人能与之相媲美.当然,他并不是唯一一位写喜剧的作家.熊佛西、李健吾、袁牧之、陈白尘、袁俊等作家,往往误把喜剧艺术当作是简单的闹剧或者滑稽剧 ②(例如熊佛西的《洋状元》,1926年),而喜剧艺术的魅力在丁西林早期作品中已得到了充分的展现,他利用喜剧来对当代中国风俗发表个人评论.
胫骨平台骨折和胫骨远端 Pilon 骨折是典型的关节周围骨折,其解剖形状不规则,靠近关节面的部分宽大且松质骨多,一旦骨折常常会出现松质骨的塌陷压缩,出现骨缺损.目前处理塌陷骨折的方式是通过翘拨或隧道顶起对骨块进行复位,这样就使骨缺损的体积进一步增大.因而处理平台骨折和Pilon骨折时骨移植术是必要的,对于植骨术的选择目前有很多方法,有自体骨移植、同种异体骨移植和骨代替物移植[1-3].
The objective of this study was to use finite element models to investigate the biomechanics of stable thoracolumbar burst fracture repair using unilateral short-segment fixation and 4 alternate pedicle screw systems.Four posterior pedicle screw systems were compared for unilateral short-segment fixation using finite element models: intermediate bilateral short pedicle screw fixation, intermediate bilateral long pedicle screw fixation, intermediate unilateral short pedicle screw fixation, and intermediate unilateral long pedicle screw fixation. We compared range of motion (ROM), von Mises stresses on the implants, and stress on the intervertebral discs superior and inferior to the injured vertebra during simulated spinal movements.There were no significant differences in ROM, von Mises stress, or intervertebral disc stress among the 4 intermediate pedicle screw fixation techniques for all spinal movements evaluated. In addition, there were no consolidated trends depicting beneficial differences between the short and long screw models, or between the unilateral and bilateral screw models.ROM, von Mises stress, and intervertebral disc stress are the same across the 4, posterior short-segment fixation techniques evaluated using finite element models. The simplest technique-posterior short segment fixation combined with intermediate unilateral short pedicle screw fixation-is a feasible treatment strategy for stable thoracolumbar fracture.
