Pulmonary embolism after shoulder surgery:Is it a real threat?

Pulmonary embolism(PE)is a rare but devastating complication of shoulder surgery.Apart from increased morbidity and mortality rates,it may significantly impair postoperative recovery and functional outcome.Its frequency accounts for up to 5.7%of all shoulder surgery procedures with a higher occurrence in women and patients older than 70 years.It is most commonly associated with thrombophilia,diabetes mellitus,obesity,smoking,hypertension,and a history of malignancy.PE usually occurs secondary to upper or lower-extremity deep vein thrombosis(DVT).However,in rare cases,the source of the thrombi cannot be determined.Prophylaxis for PE following shoulder surgery remains a topic of debate,and the standard of care does not routinely require prophylactic medication for DVT prophylaxis.Early ambulation and elastic stockings are important preventative measures for DVT of the lower extremity and medical agents such as aspirin,low-molecular-weight heparin,and vitamin K antagonists are indicated for high-risk patients,long-lasting operations,or concomitant severe acute respiratory syndrome coronavirus 2 infection.The most common symptoms of PE include chest pain and shortness of breath,but PE can also be asymptomatic in patients with intrinsic tolerance of hypoxia.Patients with DVT may also present with swelling and pain of the respective extremity.The treatment of PE includes inpatient or outpatient anticoagulant therapy if the patient is hemodynamically unstable or stable,respectively.Hemodynamic instability may require transfer to the intensive care unit,and cardiovascular arrest can be implicated in fatal events.An important issue for patients with PE in the postoperative period after shoulder surgery is residual stiffness due to a delay in rehabilitation and a prolonged hospital stay.Early physiotherapy and range-of-motion exercises do not adversely affect the prognosis of PE and are highly recommended to preserve shoulder mobility and function.

Mechanisms of shoulder trauma: Current concepts

Acute traumatic injuries to the glenohumeral articulation are common.The types of injuries depend on age,muscle strength,bone density,and biomechanics of the traumatic event.Understanding the different mechanisms of trauma and how they affect the functional anatomical structures of the shoulder joint is crucial for the treatment of these lesions.Therefore,when clinicians have knowledge of these mechanisms they can accurately diagnose and treat shoulder pathology and predict distinct injury patterns.Here,we have described the fundamentals of the mechanisms of injury of the glenohumeral dislocation,dislocation with fracture of the humeral head,and the proximal humerus fracture.We have focused on common injury mechanisms and the correlation with radiological diagnostics.Radiological and laboratory findings of distinct types of injury were also discussed.

Surgical Treatment of Anterior Shoulder Instabilities Using the Latarjet Technique (about 40 Cases)

Purpose: Surgical treatment of chronic anterior shoulder instability is a difficult therapeutic challenge for contact athletes. The aim of our study is to evaluate the clinical and radiological results of 40 cases of chronic anterior shoulder instability treated in our institution by Latarjet technique. Methods: We report our experience with the intervention of Latarjet modified by the analysis of a retrospective study of 40 cases. They were all young athletic men, with an average age of 29 years with a predominance of the dominant shoulder. Results: Eighty percent had bone lesions, the first dislocation being traumatic (plating). One patient had a recurrence of his instability due to a new trauma and 67% resumed sport within an average period of eight months, some of whom still had functional discomfort in sports practice (9 patients). After an average follow-up of 75 months, 93% of patients were satisfied with their intervention. Only two mechanical complications were observed. Conclusion: Chronic anterior shoulder instability is pathology of young and active subjects. The preregulenoid coracoid block according to Latarjet represents the therapeutic method of choice in the treatment of chronic anterior instabilities of the shoulder, especially in young and athletic subjects. The result of this intervention remains good despite the complications that can occur such as pseudarthrosis, osteoarthritis, lysis or mobility of the screw.

Buechel Pappas Resurfacing Shoulder Replacement: Evolution and over 40 Years of Clinical Experience

Background: Early exploration of the semi constrained “Floating-Socket” total shoulder replacement (TSR) in 1974 led to a proliferation of various unconstrained designs that allowed resection or retention of the humeral head, depending upon the pathological process involved. Degenerative glenohumeral arthritis with mild to moderate involvement of subchondral bone allowed for a resurfacing option, while severe humeral head involvement required a partial or full humeral head replacement attached to an intramedullary stem for fixation. All components evolved from cemented to cementless application by 1982. The purpose of this paper is to describe the progression of Buechel-Pappas (B-P) shoulder replacement development from the early 1970’s in both cemented and cement less applications. Methods: Clinical evaluations of “Floating-Socket” TSR, followed by B-P stem-type, resurfacing types, bipolar-type and revision components, all of which comprise the B-P Shoulder Replacement System, were performed over a 49-year period. Results: “Floating-Socket” implants improved the results of simple, constrained ball-in-socket designs, but generally failed by glenoid component loosening in both chimpanzee and human applications. Unconstrained resurfacing-type components, both anatomical humeral head and full proximal humeral components, were quite successful, with minimal failures observed in long-term studies. Bipolar salvage implants, used for severe proximal deficiencies, revisions and massive rotator cuff arthropathy, were also very successful;providing overhead range of motion in many patients. Conclusions: Resurfacing hemiarthroplasty, in patients with intact or repairable rotator cuff mechanisms, gave the most satisfactory results and were the least technically complicated to perform, requiring minimal instrumentation. Resurfacing of full proximal humeral deficiencies, using femoral resurfacing components, gave similar clinical results to more complex semi-constrained devices, also with less technical difficulties and simple instrumentation.

Stresses in the Scapular Fossa Do Not Exceed the Yield Stress When Elevated up to 135 Degrees of Abduction after Reverse Shoulder Arthroplasty

Reverse shoulder arthroplasty (RSA) is an effective treatment for rotator cuff tears. Despite its advantages, complications occur at a high rate. Complications requiring revision include a high rate of base plate failure, 38% of which are due to instability. The primary stability the base plate ensures is a crucial factor and, thus, is the subject of much debate in clinical studies and biomechanical research. This study is aimed to provide data that will contribute to the base plate’s pri-mary stability and glenoid longevity by clarifying the stresses at the scapular fossa and base plate interface associated with elevation after RSA. A 3D finite element model was created from the DICOM data for the scapulohumeral joint and SMR shoulder system. For loading conditions, 30 N was applied for each posi-tion with abduction angles of 0, 45, 90, and 135 degrees. A three-dimensional fi-nite element analysis was performed using the static implicit method with LS-DYNA. The von Mises stresses in the scapular fossa were found not to exceed the yield stress on the bone even after elevation to an abduction angle of 135 de-grees after RSA. It is rough to uniformly compare the yield stress and the von Mises stress, but it was inferred that the possibility of fracture is low unless a large external force is applied. A maximum von Mises stress showed 0 degrees of abduction, suggesting that the lowered position is in a more severe condition than the elevated position. If better improvement is desired, it may be necessary to devise ways to reduce the stress on the upper screw. .

Identification method of shoulder torque of screw-on curve of premium threaded connections for OCTG

The meaning of each part of the screw-on curve,the definition of shoulder torque,and the common characteristics of the screw-on curve are introduced.Moreover,the principle and shortcomings of the commonly used method of curve curvature radius are discussed.A new method of sealing surface deformation is proposed based on the requirements of shoulder torque recognition.The calculation method and principle of PW value are elucidated and the advantages of this method are summarized.The proposed method considers the difference value of tightening torque and calculates the elastic deformation of the sealing surface,accurately reflecting the state of the thread compound and the correlation between torque change and elastic deformation of the sealing surface after compression.

Effect of electroacupuncture combined with rehabilitation techniques on shoulder function in patients with rotator cuff injuries

BACKGROUND The rotator cuff is located below the acromion and deltoid muscles and comprises multiple tendons that wrap around the humeral head,maintaining shoulder joint stability.AIM To explore the effect of electroacupuncture combined with rehabilitation techniques on shoulder function in patients with rotator cuff injuries.METHODS We selected 97 patients with rotator cuff injuries treated in the People's Hospital of Yuhuan from February 2020 to May 2023.Patients were grouped using the envelope method.RESULTS After treatment,the study group’s treatment effective rate was 94.90%(46/49 patients),significantly higher than that in the control group(79.17%,38/48 cases;P<0.05).Before treatment,there was no difference in Constant Murley Score(CMS)scores,shoulder mobility,or 36-Item Short Form Health Survey(SF-36)scale scores(P>0.05).Compared with those before treatment,the CMS scores(including pain,daily living ability,shoulder mobility,and muscle strength),all aspects of shoulder mobility(forward flexion,posterior extension,external rotation,internal rotation),and SF-36 scale scores(including physiological,psychological,emotional,physical,vitality,and health status)were higher in both groups after treatment and significantly higher in the study group(P<0.05).There was no difference in the occurrence of complications between the two treatment groups(P>0.05).CONCLUSION Electroacupuncture combined with rehabilitation techniques has a good treatment effect on patients with rotator cuff injuries,helps accelerate the recovery of shoulder function,improves the quality of life,and is highly safe.

Ultrasound of the Rotator Cuff in Non-Fractured Shoulder Trauma: 30 Cases at the Yalgado Ouedraogo University Hospital of Ouagadougou (Burkina Faso)

Introduction: Ultrasound is the imaging technique of choice for the study of rotator cuff lesions. However, in the case of shoulder trauma, it is rarely requested in our context. This study aimed to show ultrasound lesions of the rotator cuff in cases of non-fracture shoulder trauma at the CHUYO in Ouagadougou. Methodology: This was a prospective descriptive cross-sectional study running from August 1 to November 30, 2017, in the medical imaging department of CHUYO. The study population consisted of patients received in the department for ultrasound in the context of non-fracture shoulder trauma. Results: We collected 20 cases (66.67%) of rotator cuff lesions out of 30 non-fracture shoulder injuries. The mean age of the patients was 27.6 years. Road traffic accidents accounted for 60% of injuries, sports accidents for 30%, and domestic accidents for 10%. Ultrasound lesions were mainly tendon ruptures (36.67%) and tendinitis (23.33%). Ruptures were non-transfixing in 90.90% of cases. The supraspinatus was the most affected (81.81%). Conclusion: Ultrasound can help diagnose rotator cuff injuries, particularly in non-fractured shoulder trauma.

High rate of clinically relevant improvement following anatomical total shoulder arthroplasty for glenohumeral osteoarthritis

BACKGROUND The minimal clinically important difference(MCID)is defined as the smallest meaningful change in a health domain that a patient would identify as important.Thus,an improvement that exceeds the MCID can be used to define a successful treatment for the individual patient.AIM To quantify the rate of clinical improvement following anatomical total shoulder arthroplasty for glenohumeral osteoarthritis.METHODS Patients were treated with the Global Unite total shoulder platform arthroplasty between March 2017 and February 2019 at Herlev and Gentofte Hospital,Denmark.The patients were evaluated preoperatively and 3 months,6 months,12 months,and 24 months postoperatively using the Western Ontario Osteoarthritis of the Shoulder index(WOOS),Oxford Shoulder Score(OSS)and Constant-Murley Score(CMS).The rate of clinically relevant improvement was defined as the proportion of patients who had an improvement 24 months postoperatively that exceeded the MCID.Based on previous literature,MCID for WOOS,OSS,and CMS were defined as 12.3,4.3,and 12.8 respectively.RESULTS Forty-nine patients with a Global Unite total shoulder platform arthroplasty were included for the final analysis.Mean age at the time of surgery was 66 years(range 49.0-79.0,SD:8.3)and 65%were women.One patient was revised within the two years follow-up.The mean improvement from the preoperative assessment to the two-year follow-up was 46.1 points[95%confidence interval(95%CI):39.7-53.3,P<0.005]for WOOS,18.2 points(95%CI:15.5-21.0,P<0.005)for OSS and 37.8 points(95%CI:31.5-44.0,P<0.005)for CMS.Two years postoperatively,41 patients(87%)had an improvement in WOOS that exceeded the MCID,45 patients(94%)had an improvement in OSS that exceeded the MCID,and 42 patients(88%)had an improvement in CMS that exceeded the MCID.CONCLUSION Based on three shoulder-specific outcome measures we find that approximately 90%of patients has a clinically relevant improvement.This is a clear message when informing patients about their prognosis.

Microstructure and mechanical properties of stationary shoulder friction stir welding joint of 2A14-T62 aluminum alloy

2A14-T62 butt joint was successfully welded by stationary shoulder friction stir welding(SSFSW)method.The results showed that using a pin with small shoulder could broaden the process window,and under a rotation speed of 2000 r/min and welding speed of 30 mm/min,joint with smooth surface,small reduction in thickness and little inner defects was obtained.The weld nugget zone was approx-imately circular,which was a unique morphology for SSFSW.The heat-affected zone(HAZ)and thermo-mechanically affected zone(TMAZ)were both quite narrow due to the lower heat input and slight mechanical action of the stationary shoulder.The fraction of high angle grain boundaries(HAGBs)exhibited a“W”shape along horizontal direction(from advancing side to retreating side),and the minim-um value located at HAZ.The average ultimate tensile strength and elongation of the joint were 325 MPa and 4.5%,respectively,with the joint efficiency of 68.3%.The joint was ductile fractured and the fracture surface contained two types of dimples morphology in different re-gions of the joint.Microhardness distribution in the joint exhibited a“W”shape,and the difference along the thickness direction was negli-gible.The joint had strong stress corrosion cracking susceptibility,and the slow stain rate tensile strength was 139 MPa.Microcrack and Al2O3 particulates were observed at the fracture surface.

Study on the Effect of Repetitive Peripheral Magnetic Stimulation Combined with Conventional Rehabilitation Measures on Shoulder Dysfunction in Early Stroke

Objective:To study the effect of repetitive peripheral magnetic stimulation(rPMS)combined with conventional rehabilitation measures on shoulder dysfunction in early stroke.Methods:60 patients with shoulder dysfunction in early stroke were selected,and all of them were admitted to our hospital from August 2021 to August 2023.The patients were randomly grouped into a control group(conventional rehabilitation measures intervention,30 cases)and an intervention group(rPMS and conventional rehabilitation measures intervention,30 cases)according to the lottery method.The pain scores,shoulder mobility,and motor function scores of the two groups were compared.Results:The pain score was lower in the intervention group,and the shoulder mobility and motor function scores were higher in the intervention group(P<0.05)as compared to that of the control group.Conclusion:The effect of combining rPMS and conventional rehabilitation measures in treating shoulder dysfunction in early stroke was remarkable and should be popularized.

REVIEW OF ACUPUNCTURE FOR FROZEN SHOULDER

Objective To assess the efficacy and possible adverse effects of acupuncture on frozen shoulder. Methods Based on the key words, i.e. acupuncture, electroacupuncture, acupuncture-moxibustion, frozen shoulder, adhesive capsulitis, shoulder disorders etc., the Chinese databases were retrieved, including Oochrane Musculoskeleta Group, Oochrane Controlled Trials Register, Oochrane Complementary Medicine Field, and the central database of the Oochrane Library as well as MEDLINE, EMBASE and Chinese Biomedical CD （OBM-disc）. 20 Chinese medical journals and relevant academic conference proceedings have been searched manually. The reference lists of identified documents were checked as the supplementary retrieval. Results 6 randomized controlled trials on frozen shoulder with acupuncture and electroacupuncture were included, indicating quite advanced study quality. There were 34 to 257 participants in the trials, 668 in total. The total OR of CMS/OSA was OR 3.49 （95 % CI - 2.64 to 9.63）, the total OR of VAS was OR - 1.24 （95% CI -3.50 to 1.01）, the total OR of ROM was OR 35.70 （95% CI 22.91 to 48.49）; the total OR of MELLE was OR 4.30 （95% OI 2.32 to 7.98）. Conclusion It is shown in the present limited inclusive trials on frozen shoulder that acupuncture is the safe therapy and effective on improving the global function, relieving pain, and improving the range of motion of shoulder. All the therapeutic effects of acupuncture are superior to those in control group. However, much more high quality trials are required to provide much stronger evidence. Additionally, much more evidences on validity of frozen shoulder with other assessing indexes involved are required in the treatment with acupuncture.

肩关节镜下喙突单隧道固定与无隧道悬吊固定治疗急性Ⅲ-Ⅴ型肩锁关节脱位

背景:目前国内外对关节镜下喙突无隧道悬吊固定与喙突单隧道固定治疗肩锁关节脱位的术后疗效研究报道较少,两种术式的具体临床疗效及是否存在其他风险有待探索。目的:比较关节镜下使用TightRope带袢带钢板喙突单隧道固定与喙突无隧道悬吊固定治疗急性Ⅲ-Ⅴ型肩锁关节脱位的短期临床疗效。方法:回顾性分析2019年6月至2022年9月新疆医科大学第六附属医院收治符合纳入标准的45例肩锁关节脱位患者,根据手术治疗方案分为2组,喙突单隧道组20例行肩关节镜下喙突单隧道固定,喙突无隧道组25例行肩关节镜下喙突无隧道悬吊固定。比较两组手术时间、切口长度及围术期失血量;对比两组术前、术后3个月及末次随访时肩关节Constant-Murley评分、目测类比评分、美国肘肩关节外科医师协会评分及术中、术后并发症等评价指标。结果与结论:①所有患者均顺利完成手术,术中无重要神经、血管损伤,喙突无隧道组手术时间较喙突单隧道组更短,差异有显著性意义(P<0.05),两组术中出血量、切口长度无显著差异(P>0.05);②所有患者随访12-24个月,平均随访(15.29±2.73)个月;③喙突单隧道组内比较:在术后3个月及末次随访时,目测类比评分较术前显著降低(P<0.05);Constant-Murley评分、美国肘肩关节外科医师协会评分较术前显著增加(P<0.05);喙突无隧道组内比较:在术后3个月及末次随访时,目测类比评分较术前显著降低(P<0.05);Constant-Murley评分、美国肘肩关节外科医师协会评分较术前显著增加(P<0.05);两组比较:在术后3个月随访时,喙突无隧道组Constant-Murley评分高于喙突单隧道组(P<0.05);两组间目测类比评分、美国肘肩关节外科医师协会评分相比差异无显著性意义(P>0.05);在术前及末次随访时,两组各评分在对应时间点之间比较差异均无显著性意义(P>0.05);④术中、术后并发症:喙突单隧道组在术中钻取隧道时发生1例喙突皮质破裂骨折,1例在术后3个月出现复位丢失,予以钩钢板+喙肩韧带转位重新复位固定;所有患者在末次随访中肩锁关节功能恢复良好且未发生再脱位;⑤提示关节镜下两种手术方法治疗急性Ⅲ-Ⅴ型肩锁关节脱位均具有创伤小、复位和固定可靠及术后肩关节功能恢复良好等优点,但是与喙突单隧道技术相比,喙突无隧道悬吊固定需要的手术时间更短、短期肩关节功能恢复快且避免了在喙突上建立骨隧道,减少了术中喙突发生医源性骨折的概率,安全性更高。

有限元分析不同程度冈上肌断裂对肩关节应力的影响

背景:目前研究冈上肌的精细解剖及各亚区域的生物力学表现的实验较多,但是对冈上肌不同区域的损伤所带来的肩关节应力的影响鲜有耳闻。很有必要了解不同区域的冈上肌损伤对关节软骨及关节盂的应力大小及分布的影响,从而给临床诊治提供一些理论支持。目的:探究在三维有限元软件中模拟不同程度的冈上肌断裂对肱骨软骨面、关节盂唇及关节盂软骨关节面的最大应力值。方法:获取正常健康的肩关节CT或MRI导入Mimics、Geomagic进行提取模型,再通过Soildworks对模型构建,再对各个模型的冈上肌进行不同程度的损伤,模拟出不同区域的断裂。最后导入机械软件Ansys,进行三维有限元生物力学分析,计算肱骨软骨面、关节盂唇及关节盂软骨关节面的应力数值。结果与结论:①随着冈上肌损伤程度的加重肩关节软骨面及盂唇的应力也会增加;②冈上肌前部在各区域中最为重要;③不同程度的冈上肌断裂对肩关节盂唇面的软骨应力大小有影响,而应力的分布区域无明显改变;④提示肩关节水平外展起始时,前部发挥着重要的作用,其次为后部深区;当冈上肌前部损伤时肩关节软组织应力增加明显,还容易引起关节盂唇顶部及关节盂软骨前下方的损伤。

give someone the cold shoulder探源

give someone the cold shoulder的意思是“采取冷淡的态度”。shoulder是指“牛羊等连前腿在内的肩肉”,因此,所谓cold shoulde就是“凉了的前腿肉”的意思。古时候有这样的风俗习惯:在招待贵客时,飨以美味佳肴;对于行商和乞丐,则给“凉了的前腿肉”吃。这就是give someone thecold shoulder具有“采取冷淡态度”意思的来源。在日常会话中,give someone the cold shoulder, 既可以指表示冷淡的耸肩动作,也可以指“采取冷淡的态度”。例如:

Conclusion The therapy of acupuncture combined with massage could improve the function of the affected shoulder joint caused by acute cerebral infarction, and enhance therapeutic effect.

Frozen shoulder:A systematic review of therapeutic options

Frozen shoulder is a common disease which causes significant morbidity. Despite over a hundred years of treating this condition the definition, diagnosis, pathology and most efficacious treatments are still largely unclear. This systematic review of current treatments for frozen shoulder reviews the evidence base behind physiotherapy, both oral and intra articular steroid, hydrodilatation, manipulation under anaesthesia and arthroscopic capsular release. Key areas in which future research could be directed are identified, in particular with regard to the increasing role of arthroscopic capsular release as a treatment.

Pain management of hemiplegic shoulder pain post stroke in patients from Nanjing,China

We selected 106 hemiplegic patients with shoulder pain hospitalized after stroke from three hospi- tals in Nanjing, China between February 2007 and January 2012. All patients had complete clinical data sets and accounted for 45.5% of the inpatients because of stroke. Results showed that the number of patients with hemiplegic shoulder pain post stroke increased yearly, attacking mainly males 50-69 years of age. Of 106 patients, there were 60 cases （56.6%） of adhesive capsulitis, 19 （17.9%） of shoulder subluxation, 14 （13.2%） of complex regional pain syndrome, and 13 （12.6%） of central pain. The main symptoms were shoulder pain （100%）, limit of shoulder mobility （98.1%）, and adhesion of the scapula （56.6%）. MRI of the shoulder showed tendon and ligament lesions （57.1%） and rotator cuff tear （38.1%）. 53.8% of central pain was related to the thalamus, in addition to the basal ganglia, brain stem, and cerebellopontine angle. Shoulder pain, upper limb motor function, and function independence were significantly improved after comprehensive rehabilitation. In par- ticular, electroacupuncture based on basic physical therapy exhibited efficacy on shoulder subluxa- tion and complex regional pain syndrome. Multiple linear regression results showed a negative re- lationship of efficacy of pain management with the attack period of shoulder pain, involvement of the posterior limb of the internal capsule, and duration between onset and rehabilitation treatment, but a positive correlation with pain-related education, pain regression period, and pain diagnosis.
