BACKGROUND:Traumatic brain injury (TBI) is a common public health problem. The optimal timing of fracture fixation in patients with TBI has remained controversial. We conducted a meta-analysis to quantitatively discuss the effects of fixation timing on the prognosis of patients with extremity fracture and concomitant TBI. METHODS:A systematic search was performed in PubMed, EMBASE, the Cochrane Library and 4 Chinese databases from the inception date to May 19, 2019. Randomized controlled trials and cohort studies comparing early and late fracture fixation in adults with TBI concomitant with extremity fractures were selected. The risk ratio (RR) and standardized mean difference were calculated. RESULTS:A total of 14 cohort studies involving 1046 patients fulfilled our criteria. No statistically significant association was found between fixation timing and mortality rate (RR, 1.34; 95% confidence interval [CI], 0.89-2.01). No significant association was found between fracture fixation timing and the incidence of death among the patients with severe TBI (RR, 1.82; 95% CI, 0.50-6.66), moderate or more serious TBI (RR, 3.78; 95% CI, 0.53-26.78), and unrestricted TBI type (RR, 0.80; 95% CI, 0.38-1.68). No significant association was found between fracture fixation timing and neurologic complications (RR, 0.71; 95% CI, 0.45-1.11). When the cutoff for fixation timing was set at 14 days, the incidence of nonunion or malunion in the earlier fixation group was lower than that in the later fixation group (RR, 0.39; 95% CI, 0.17-0.91). CONCLUSION:Late fracture fixation conducted >14 days after injury was associated with nonunion or malunion. Fixation performed within 24 hours did not influence mortality or adverse neurologic events.
背景: 创伤性脑损伤 (TBI) 是常见的公共卫生问题。TBI患者骨折固定的最佳时机仍存在争议。我们进行了一项荟萃分析，定量讨论固定时机对四肢骨折合并TBI患者预后的影响。 方法: 在PubMed、EMBASE、the Cochrane Library和 4 个中文数据库中进行系统检索，检索时间为 2019 年 5 月 19 日。选择比较成人TBI伴四肢骨折早期和晚期骨折固定的随机对照试验和队列研究。计算风险比 (RR) 和标准化平均差。 结果: 共有 14 项队列研究，涉及 1046 例患者，符合我们的标准。未发现固定时机与死亡率之间存在统计学显著相关性 (RR，1.34; 95% 置信区间 [CI]，0.89-2.01)。未发现骨折固定时机与重度TBI患者死亡发生率之间存在显著相关性 (RR，1.82; 95% CI，0.50-6.66)，中度或更严重的TBI (RR，3.78; 95% CI，0.53-26.78) 和非限制性TBI类型 (RR，0.80; 95% CI，0.38-1.68)。未发现骨折固定时机与神经系统并发症之间存在显著相关性 (RR，0.71; 95% CI，0.45-1.11)。当固定时机截断值设定在 14 天时，早期固定组的骨不连或畸形愈合发生率低于后期固定组 (RR，0.39; 95% CI，0.17-0.91)。 结论: 伤后> 14 天进行的晚期骨折固定与骨不连或畸形愈合有关。24 小时内进行的固定不影响死亡率或不良神经事件。
METHODS:BACKGROUND:Postoperative cognitive dysfunction (POCD) is a common complication after orthopedic surgery, which is not conducive to the prognosis of the elderly. AIMS:We performed this study to investigate the effects of oxycodone applied for patient-controlled intravenous analgesia (PCIA) on postoperative cognitive function in elderly patients after total hip arthroplasty (THA). METHODS:Ninety-nine participants were enrolled and allocated into two groups: oxycodone group (group O) and sufentanil group (group S). The primary outcome was the incidence of POCD, diagnosed according to the changes in the Mini-mental status examination (MMSE) and Montreal Cognitive Assessment (MoCA) scores. The secondary outcomes included the plasma levels of S-100B protein and neuron-specific enolase (NSE), the amount of postoperative analgesic consumption and the incidence of adverse reactions. RESULTS:The incidence of POCD was significantly lower in patients receiving oxycodone up to the 3rd postoperative day (POD, 1st POD 27.3% vs. 51.1%, P = 0.021; 3rd POD 20.5% vs. 40.0%, P = 0.045), as compared to patients receiving sufentanil. The MMSE and MoCA scores of both groups decreased to varying degrees. However, compared with group S, the MMSE scores at 1st POD, 3rd POD, 5th POD and 7st POD in group O were higher than that in group S, while MoCA scores at 1st POD, 3rd POD and 5th POD in group O were higher. Compared with group S, the plasma levels of S-100B protein in group O at 4 h, 8 h, 12 h post-surgery were lower. While the plasma levels of NSE in group O at 4 h, 8 h, 12 h, 24 h post-surgery were lower. Number of PCIA boluses and consumption of analgesic drug during the first two POD were similar between two groups. However, postoperative incidence of nausea, vomiting and pruritus was significantly lower in patients receiving oxycodone. CONCLUSION:Oxycodone applied for PCIA in elderly patients after THA could reduce the incidence of POCD, improve postoperative cognitive function and decrease the adverse reactions.
METHODS:BACKGROUND:Primary treatment for Blount disease has changed in the last decade from osteotomies or staples to tension band plate (TBP)-guided hemiepiphysiodesis. However, implant-related issues have been frequently reported with Blount cases. The purpose of our study is to evaluate the surgical failure rates of TBP in Blount disease and characterize predictors for failure. METHODS:We performed an Institutional Review Board-approved retrospective chart-review of pediatric patients with Blount disease to evaluate the results of TBP from 2008 to 2017 and a systematic literature review. Blount cases defined as pathologic tibia-vara with HKA (hip-knee-ankle) axis and MDA (metaphyseal-diaphyseal angle) deviations ≥11 degrees were included in the analysis. Surgical failure was categorized as mechanical and functional failure. We studied both patient and implant-related characteristics and compared our results with a systematic review. RESULTS:In 61 limbs of 40 patients with mean follow-up of 38 months, we found 41% (25/61) overall surgical failure rate and 11% (7/61) mechanical failure rate corresponding to 11% to 100% (range) and 0% to 50% (range) in 8 other studies. Statistical comparison between our surgical failure and nonfailure groups showed significant differences in deformity (P=0.001), plate material (P=0.042), and obesity (P=0.044) in univariate analysis. The odds of surgical failure increased by 1.2 times with severe deformity and 5.9 times with titanium TBP in the multivariate analysis after individual risk-factor adjustment. All 7 mechanical failures involved breakage of cannulated screws on the metaphyseal side. CONCLUSIONS:Most of the studies have reported high failure rates of TBP in Blount cases. Besides patient-related risk factors like obesity and deformity, titanium TBP seems to be an independent risk factor for failure. Solid screws were protective for mechanical failure, but not for functional failure. In conclusion, efficacy of TBP still needs to be proven in Blount disease and implant design may warrant reassessment. LEVEL OF EVIDENCE:Level III-retrospective comparative study with a systematic review.
METHODS:INTRODUCTION:As cancer treatments continue to improve the overall survival rates, more patients with a history of cancer will present for anatomic total shoulder arthroplasty (TSA). Therefore, it is essential for orthopaedic surgeons to understand the differences in care required by this growing subpopulation. Although the current research suggests that good outcomes can be predicted when appropriately optimized patients with cancer undergo lower extremity total joint arthroplasty, similar studies for TSA are lacking. The primary study question was to examine whether a history of cancer was associated with an increased rate of venous thromboembolism (VTE) after TSA. Secondarily, we sought to examine any association between a history of prostate and breast cancer and surgical or medical complications after TSA. METHODS:Using a national insurance database, male patients with a history of prostate cancer and female patients with a history of breast cancer undergoing anatomic TSA for primary osteoarthritis were identified and compared with control subjects matched 3:1 based on age, sex, diabetes mellitus, and tobacco use. Patients with a history of VTE and patients who underwent reverse TSA or hemiarthroplasty were excluded. RESULTS:Female patients with a history of breast cancer and male patients with a history of prostate cancer undergoing TSA had significantly higher incidences of acute VTE (including deep venous thrombosis and pulmonary embolism) compared with matched control subjects (female patients: odds ratio, 1.41; 95% confidence interval, 1.10 to 1.81; P = 0.024 and male patients: odds ratio, 1.37; 95% confidence interval, 1.05 to 1.79; P = 0.023). No significant differences were noted in the incidences of any other complications assessed. CONCLUSION:Although a personal history of these malignancies does represent a statistically significant risk factor for acute VTE after anatomic TSA, the overall VTE rate remains modest and acceptable. The rates of other surgical and medical complications are not significantly increased in patients with a history of these cancers after TSA compared with control subjects.
