Analysis of CT and MRI in the Diagnosis of Shoulder Joint Injury

Objective: To observe the effect of multi-slice spiral CT and magnetic resonance imaging (MRI) in the diagnosis of shoulder injury. Methods: 120 patients with shoulder injury who were treated in our hospital (January 2020 to December 2021) and underwent surgical treatment were diagnosed as shoulder injury. They were divided into CT group, MRI group and joint diagnosis group. The detection rates of the two methods were compared. Results: In the diagnosis of shoulder injury, MRI group was higher than CT group, and the joint diagnosis group was higher than the other two groups. Conclusion: In the diagnosis of shoulder injury, the joint examination of multi-slice spiral CT and magnetic resonance imaging (MRI) can obtain a higher diagnostic rate and ideal effect.

High Frequency Ultrasound in Determining the Causes of Acute Shoulder Joint Pain

Shoulder ultrasonography is approved as the examination of choice for rotator cuff abnormality in many centers around the world since it is an inexpensive and safe tool for investigation of rotator cuff abnormalities. The goal of this study was to determine the ultrasound findings in patients with acute shoulder joint pain, and also to identify possible predictors of shoulder pain, as well as to compare the ultrasound diagnostic performance to that of MRI in such condition. A total of 65 (mean age 28 ± 1.2 years) consequential patients were recruited for a period of six months between July 2015 and June 2016 in this study. Collected data were confined on age, medical history, and clinical symptoms. Shoulder ultrasound was performed with a linear array transducer (10 - 15 MHz) connected to HI vision Avius ultrasound unit;Hitachi. MRI for the shoulder joint was performed in all cases to confirm the ultrasound results, using 1.5-T MRI system (Magnetom Espree);Siemens. Statistical analysis was completed using the standard Statistical Package for the Social Sciences (SPSS Inc., Chicago, IL, USA) version 20 for windows. Ultrasound manages to determine the causes of acute shoulder joint pain in 98% of the patients. Fitted achievement values for shoulder ultrasound in the diagnosis the causes of shoulder joint pain were 100% sensitivity and a range of 96% to 100% of accuracy. Ultrasound presents a high sensitivity and accuracy in diagnosis a wide spectrum of shoulder joint lesions, with a diagnostic performance near to that of MRI.

A Case of Septic Arthritis of the Shoulder Joint That Developed after Suprascapular Nerve Block

Septic arthritis of the shoulder is uncommon in the immunocompetent patient with no previous risk factors for joint infection. We treated an immunocompetent patient who developed septic arthritis of the shoulder after suprascapular nerve block for pain due to rotator cuff tear. An 80-year-old man with no underlying disease visited a nearby orthopedics clinic with complaint of left shoulder joint pain. Left suprascapular nerve block was performed, but the pain gradually aggravated. On the day after the block, he had a fever of 39°C and came to our department. On examination, enlargement and tenderness were present at the injection site. Cellulitis at the site was suspected. He was admitted and administration of a cephem anti-biotic was started. Pain subsequently decreased. Magnetic resonance imaging (MRI) performed 4 days after hospitalization showed massive effusion close to the injection site. The effusion spread into the joint cavity through the tear site of the supraspinatus. Septic arthritis of the shoulder was strongly suspected, open irrigation and debridement were performed 11 days after hospitalization. After surgery, pain immediately improved. In our case the extra-articular infection caused by suprascapular nerve block considered to spread into the shoulder joint cavity through the site of rotator cuff tear, although there have been no reports of such cases. This case suggests the possibility that patients with rotator cuff tear may easily develop septic arthritis because extra-articular infection may spread into the joint cavity through the site of tear.

Shoulder joint flexibility in top athletes

Joint range of motion (ROM) is very important in daily activities, sport and in clinical diagnosis. Many factors have been reported to influence joint ROM. Musculoskeletal adaptation and some special side effects due to his or her physical demands and movement patterns in professional athletes are very important subjects in sport sciences. The present study is a comparison of shoulder joint ROM in elite athlete and non-athlete groups and its relationship to their age, post and years of their tournament play. The subjects in this study included 106 men with mean age (23.65 ±3.45) and mean years of tournament play (5.60 ±2.23). The groups of subjects included 26 handball players, 25 volleyball players, 25 soccer players and 30 non-athletes. Data were collected through questionnaires and inspection, and subjects’ ROM was measured by “Leighton flex- ometer” (r = 0.90 – 0.99) in external rotation and abduction of shoulder joint in dominant and non-domi- nant hands. Data were analyzed by correlation coefficient, t – test, ANOVA and post hock Schaffe test. The results showed that an increase in age and years of tournament play reduced the shoulder ROM of subjects (p ≤ 0.05). There were significant differences in shoulder ROM among athletic groups. Additionally, there are significant differences between dominant and non-dominant hands (p ≤ 0.05). It can be concluded that more specific stretching exercises and warm-up for shoulder in all athletes and especially in older and experienced players should be performed by coaches. The results also emphasized routine screening, corrective exercise programs and a design of preventing strategies by athletic trainers and coaches.

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.

Adaptive Multi-Objective Optimization of Bionic Shoulder Joint Based on Particle Swarm Optimization

To get the movement mode and driving mechanism similar to human shoulder joint,a six degrees of freedom(DOF) serial-parallel bionic shoulder joint mechanism driven by pneumatic muscle actuators(PMAs)was designed.However,the structural parameters of the shoulder joint will affect various performances of the mechanism.To obtain the optimal structure parameters,the particle swarm optimization(PSO) was used.Besides,the mathematical expressions of indexes of rotation ranges,maximum bearing torque,discrete dexterity and muscle shrinkage of the bionic shoulder joint were established respectively to represent its many-sided characteristics.And the multi-objective optimization problem was transformed into a single-objective optimization problem by using the weighted-sum method.The normalization method and adaptive-weight method were used to determine each optimization index's weight coefficient;then the particle swarm optimization was used to optimize the integrated objective function of the bionic shoulder joint and the optimal solution was obtained.Compared with the average optimization generations and the optimal target values of many experiments,using adaptive-weight method to adjust weights of integrated objective function is better than using normalization method,which validates superiority of the adaptive-weight method.

Therapeutic efficacy of acupuncture combined with neuromuscular joint facilitation in treatment of hemiplegic shoulder pain

BACKGROUND Stroke is a type of cerebrovascular disease with high prevalence,mortality,and onset of disability.As a neurodevelopmental therapy,neuromuscular joint facilitation(NJF)is widely used in the treatment of orthopedic and neurological disorders in the clinical practice.It is mainly used for central nervous system diseases or orthopedic diseases,movement disorders,and pain rehabilitation.According to related studies,NJF can also be used as a rehabilitation treatment in patients with hemiplegic shoulder pain(HSP).AIM To investigate the clinical efficacy of acupuncture combined with NJF in patients with HSP.METHODS Forty patients with HSP were randomly divided into a treatment group and a control group.The treatment group was treated with acupuncture combined with NJF and the control group was treated with acupuncture alone.All patients were assessed by using the visual analogue scale(VAS),Fugl-Meyer assessment(FMA),Barthel index(BI),and passive range of motion(PROM)before and after the training.All the clinical data were analyzed using SPSS 20.0 statistical software.RESULTS There was no statistical difference in the general characteristics between the two groups.In the terms of duration of treatment,age,and pre-treatment indicators,the two groups were comparable(P>0.05).After the treatment,VAS,PROM,BI,and FMA scores were significantly improved in the two groups of patients(P<0.05).The VAS,PROM and FMA scores were significantly higher in the treatment group than in the control group(P<0.05).However,there was no significant difference in BI scores between the two groups(P>0.05).CONCLUSION Both acupuncture alone and acupuncture combined with NJF in the treatment of HSP are effective,and can improve the clinical symptoms of patients.Acupuncture combined with NJF can improve the upper limb motor function,relieve pain,and increase joint mobility in patients with HSP.The combination therapy is better than acupuncture alone.However,there is no significant difference in improving the score of patients’self-care ability.

Restoration of the joint geometry and outcome after stemless TESS shoulder arthroplasty

AIM To evaluate the joint geometry and the clinical outcome of stemless, anatomical shoulder arthroplasty with the TESS system.METHODS Twenty-one shoulders with a mean follow-up 18 of months were included. On scaled digital radiographs the premorbid center of rotation(CoR) was assessed and compared to the CoR of the prosthesis by using the MediC AD~? software. Additionally, the pre-and post-operative geometry of the CoR was assessed in relation to the glenoid, the acromion as well as to the proximal humerus. Radiological changes, such as radiolucencies, were also assessed. Clinical outcome was assessed with the Constant and DASH score. RESULTS Both, the Constant and DASH scores improved signifi-cantly from 11% to 75% and from 70 to 30 points, P < 0.01 respectively. There were no significant differences regarding age, etiology, cemented or metal-backed glenoids, etc.(P > 0.05). The pre-and postoperative humeral offset, the lateral glenohumeral offset, the height of the CoR, the acromiohumeral distance as well as neckshaft angle showed no significant changes(P > 0.05). The mean deviation of the CoR of the prosthesis from the anatomic center was 1.0 ± 2.8 mm. Three cases showed a medial deviation of more than 3 mm. These deviations of 5.1, 5.7 and 7.6 mm and were caused by an inaccurate humeral neck cut. These 3 patients showed a relatively poor outcome scoring.CONCLUSION TESS arthroplasty allows an anatomical joint reconstruction with a very good outcome. Outliers described in this study sensitize the surgeon for an accurate humeral neck cut.
