Abstract

BACKGROUND:We evaluated survival and midterm results of pyrocarbon interposition shoulder arthroplasty (PISA) in arthritic patients younger than 65 years. METHODS:Fifty-eight PISAs (InSpyre; Tornier-Wright, Bloomington, MN, USA), implanted in 56 patients between 2010 and 2015, were prospectively observed. The mean age at surgery was 52 ± 13 years. The cause was primary osteoarthritis (18), fracture sequelae (16), post-instability arthritis (15), aseptic necrosis (3), inflammatory disease (2), and failed hemiarthroplasty (4); 34 shoulders (61%) had previously undergone surgery. Glenoid erosion was assessed in 4 grades according to the Sperling classification. Humeral erosion was also assessed in 4 grades. Multivariate analysis was used to determine predisposing risk factors for both humeral and glenoid erosion. RESULTS:At a mean follow-up of 47 ± 15 months, survival rate was 90%. Six patients (10%) required conversion to reverse total shoulder prosthesis for painful glenoid erosion (n = 2) and humeral erosion with greater tuberosity stress fractures (n = 4). The mean Constant score and subjective shoulder value significantly increased from 36 ± 14 points to 70 ± 15 points and 32% ± 14% to 75% ± 19%, respectively (P < .001). Humeral medialization was observed in 78% of the cases with increased pain score. Uncorrected anteroposterior implant subluxation (12 cases) was associated with lower Constant score (50 points vs. 72 points; P = .02) and lower subjective shoulder value (53% vs. 78%; P = .002). On multivariate analysis, no risk factors for glenoid or humeral erosion were found. CONCLUSION:At midterm follow-up, PISA does not protect from progressive glenoid erosion and can lead to greater tuberosity erosion and stress fractures. Longer follow-up is required to see whether PISA survival will be superior to that of hemiarthroplasty.

摘要

背景: 我们对年龄小于 65 岁的关节炎患者进行了热解碳间置肩关节置换术 (PISA) 的生存和中期结果评估。 方法: 前瞻性观察 2010 年至 2015 年间植入 56 例患者的 58 例PISAs (InSpyre; Tornier-Wright,Bloomington,MN,USA)。手术时的平均年龄为 52 ± 13 岁。病因为原发性骨关节炎 (18 例) 、骨折后遗症 (16 例) 、不稳定后关节炎 (15 例) 、无菌性坏死 (3 例) 、炎性疾病 (2 例) 、和失败的半髋关节置换术 (4); 34 个肩膀 (61%) 以前接受过手术。关节盂糜烂按精子分级评定 4 级。肱骨侵蚀也评估了 4 个等级。采用多变量分析确定肱骨和关节盂糜烂的易感危险因素。 结果: 平均随访 47 ± 15 个月,生存率为 90%。6 例 (10%) 患者因疼痛性关节盂侵蚀 (n = 2) 和肱骨侵蚀伴大结节应力性骨折 (n = 4) 需要转换为反向全肩关节假体。平均Constant评分和主观肩值分别从 36 ± 14 分显著提高到 70 ± 15 分和 32% ± 14% ~ 75% ± 19% (P <.001)。在疼痛评分增加的病例中,78% 的病例观察到肱骨内侧化。未矫正的前后种植体半脱位 (12 例) 与较低的Constant评分 (50 分vs. 72 分; P = .02) 和较低的主观肩值 (53% vs. 78%; P = .002)。在多变量分析中,未发现关节盂或肱骨糜烂的危险因素。 结论: 在中期随访中,PISA不能保护进行性关节盂侵蚀,并可导致大结节侵蚀和应力性骨折。需要更长时间的随访,以确定PISA生存率是否优于半髋关节置换术。

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.
