BACKGROUND:Advancements in modern medicine have led to longer life expectancy. Literature on spinopelvic fixation in elderly patients is limited. We investigated morbidity and mortality in octogenarians who underwent spinopelvic fixation. METHODS:A retrospective chart review was conducted of patients who underwent spinopelvic fixation from January 2014 through December 2018 at a single institution. Patients were grouped into the octogenarian group (OG), 80-89 years old, and comparison group (CG), 40-50 years old. Demographics; pathology; Charlson Comorbidity Index; Hounsfield units; surgery details; and clinical data including complications, intensive care unit and length of hospital stay, and mortality were collected and compared. RESULTS:Inclusion criteria were met by 26 patients (OG: n = 14; CG: n = 12). Diagnoses in the OG were deformity (42.9%), pseudarthrosis (35.7%), fracture (7.1%), infection (7.1%), and tumor (7.1%). The only significant differences in baseline patient characteristics were that Charlson Comorbidity Index was significantly higher in the OG (6.0 ± 1.4) compared with the CG (1.1 ± 1.0) (P < 0.001) and the OG had lower Hounsfield units (P < 0.001), indicating poorer bone quality. More patients in the CG underwent staged and anterior approaches compared with the OG (P = 0.031). Major and minor complication rates were 57.1% and 42.9%, respectively, in the OG (P = 0.98) and 25% and 25% in the CG (P = 0.34). Mortality rate was 14.3%. CONCLUSIONS:With an aging population, the number of patients requiring spinopelvic fixation will continue to grow. Spine surgeons must carefully weigh benefits and risks in patients with multiple comorbidities.
背景: 现代医学的进步带来了更长的预期寿命。关于老年患者脊柱骨盆固定的文献有限。我们调查了接受骨盆固定术的 80 岁以上老人的发病率和死亡率。 方法: 对 2014 年 1 月至 2018 年 12 月在单个机构接受骨盆固定术的患者进行回顾性图表回顾。将患者分为 80 岁组 (OG)，80 ~ 89 岁，对照组 (CG)，40 ~ 50 岁。收集并比较人口统计学; 病理学; Charlson合并症指数; Hounsfield单位; 手术细节; 和临床数据，包括并发症、重症监护病房和住院时间以及死亡率。 结果: 符合纳入标准的患者有 26 例 (OG: n = 14; CG: n = 12)。诊断依次为畸形 (42.9%) 、假关节 (35.7%) 、骨折 (7.1%) 、感染 (7.1%) 和肿瘤 (7.1%)。基线患者特征的唯一显著差异是，与CG (6.0 ± 1.4) 相比，OG (1.1 ± 1.0) 的Charlson合并症指数显著较高 (P < 0.001) OG的Hounsfield单位较低 (P <0.001)，表明骨质量较差。与OG相比，CG中有更多的患者接受了分期和前路手术 (P = 0.031)。OG的主要和次要并发症发生率分别为 57.1% 和 42.9% (P = 0.98)，CG的主要和次要并发症发生率分别为 25% 和 25% (P = 0.34)。死亡率为 14.3%。 结论: 随着人口老龄化，需要脊柱骨盆固定的患者数量将继续增长。脊柱外科医生必须仔细权衡多重合并症患者的获益与风险。
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.
