STUDY DESIGN:A retrospective chart review of prospectively collected data. OBJECTIVE:The aim of this study was to determine whether back-to-back scoliosis surgeries can be performed safely without compromising outcomes and the reproducibility of the practice between institutions. SUMMARY OF BACKGROUND DATA:During the summer, spinal surgeons will often book multiple cases in one day. The complexity and demands of spinal fusion surgery call into question the safety. Change of operating room staff including anesthesiologists, nurses, and neurologists may introduce new risks. METHODS:From 2009 to 2018, index AIS surgeries were included. In Groups 1, 2, and 3, surgeries were performed by a single surgeon. In Group 4, they were performed by other institutional surgeons. Group 1: first surgery of the day, Group 2: second surgery of the day, Group 3: only surgery of the day, Group 4: only surgery of the day by different institutional surgeon. Additional analysis was done to determine reproducibility after a surgeon was moved from Institution 1 to Institution 2. RESULTS:Five hundred sixty-seven AIS patients were analyzed. Group 1 patients had similar radiographic outcomes compared with Group 2 (P > 0.05). Surgical time was similar (P = 0.51), but significantly more levels fused (P = 0.01). Compared with Group 3, Group 2 had a smaller preoperative Cobb (P = 0.02), shorter surgeries (P < 0.001), and length of stay (P = 0.04) but similar complication rate (P = 1). Compared with Group 4, Group 2 had smaller preoperative Cobb (P < 0.001), shorter surgery, and lower complication rate (P = 0.03). When determining reproducibility, institution 2 patients had significantly less blood loss, shorter surgeries, and shorter lengths of stay (P < 0.05). CONCLUSION:Although long and involved, back-to-back AIS surgeries do not compromise radiographic or perioperative outcomes. Changes in operating team do not appear to impact safety, efficiency, or outcomes. This study also found that the practice is reproducible between institutions. LEVEL OF EVIDENCE:3.


研究设计: 前瞻性收集数据的回顾性图表回顾。 目的: 本研究的目的是确定背靠背脊柱侧凸手术是否可以安全地进行,而不影响结果和机构之间实践的可重复性。 背景资料摘要: 在夏季期间,脊柱外科医生经常会在一天内预订多个病例。脊柱融合手术的复杂性和需求对安全性提出了质疑。手术室工作人员包括麻醉医生、护士和神经科医生的更换可能会带来新的风险。 方法: 2009-2018 年,纳入索引AIS手术。在第 1 、 2 和 3 组中,手术由一名外科医生进行。第 4 组由其他机构外科医生进行。第 1 组: 当天的第一次手术,第 2 组: 当天的第二次手术,第 3 组: 仅当天的手术,第 4 组: 仅由不同的机构外科医生进行当天的手术。外科医生从机构 1 转移到机构 2 后,进行额外分析以确定再现性。 结果: 分析了 567 例AIS患者。组 1 患者与组 2 患者的影像学结果相似 (p> 0.05)。手术时间相似 (p = 0.51),但融合的层次明显更多 (p = 0.01)。与组 3 相比,组 2 术前Cobb较小 (p = 0.0 2),手术时间较短 (p <0.00 1),住院时间较短 (p = 0.04) 但并发症发生率相似 (p = 1)。与组 4 相比,组 2 术前Cobb较小 (p <0.001),手术时间较短,并发症发生率较低 (p = 0.03)。在确定可重复性时,机构 2 患者的失血量显著减少,手术时间更短,住院时间更短 (p <0.05)。 结论: 虽然长时间且受累,但背靠背AIS手术不会损害影像学或围手术期结果。操作团队的变化似乎不会影响安全性、效率或结果。本研究还发现,该做法在机构之间是可复制的。 证据级别: 3.

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.
