ABSTRACT
Abstract Objective The objectives of this study are to compare absolute values of acromial index (AI) and critical shoulder angle (CSA) obtained in both radiographs and magnetic resonance image (MRI) of the shoulder; and to compare the interobserver and intra-observer agreement for AI and CSA values measured in these image modalities. Methods Patients who had medical indication of investigating shoulders conditions through radiographs and MRI were included. Images were taken to two fellowship-trained shoulder surgeons, which conducted measurements of AI and CSA in radiographs and in MRI. Twelve weeks after the first evaluation, a second evaluation was conducted. Inter- and intra-observer reliability was presented as an Intraclass Correlation Coefficient (ICC) and agreement was classified according to Landis & Koch criteria. The differences between two measurements were evaluated using Bland-Altman plots. Results 134 shoulders in 124 subjects were included. Mean intra-observer ICC for CSA in X-rays and in MRI were 0.936 and 0.940, respectively; for AI, 0.908 and 0.022. Mean inter-observer ICC for CSA were 0.892 and 0.752 in X-rays and MRI respectively; for AI, ICC values were 0.849 and 0.685. All individual analysis reached statistical power (p< 0.001). Mean difference for AI values measured in X-rays and in MRI was 0.01 and 0.03 for observers 1 and 2, respectively. Mean difference for CSA values obtained in X-rays and MRI was 0.16 and 0.58 for observers 1 and 2, respectively. Conclusion Both MRI and X-rays provided high intra- and interobserver agreement for measurement of AI and CSA. Absolute values found for AI and CSA were highly correlated in both image modalities. These findings suggest that MRI is a suitable method to measure AI and CSA. Level of Evidence II, Diagnostic Study.

Objective: To observe the effects of tendon-regulating and stretching manipulation plus JIN's three-needle therapy for the shoulder on pain and shoulder joint function in subacromial impingement syndrome (SIS). Methods: Eighty patients with SIS were recruited and divided into a control group and a treatment group by the random number table method, with 40 cases in each group. The control group was given JIN's three-needle therapy for the shoulder, and the treatment group received additional tendon-regulating and stretching manipulation. The visual analog scale (VAS) score and constant-Murley score (CMS) were observed before and after the intervention, and the total effective rate was also observed. Results: The total effective rate was 92.5％ in the treatment group versus 70.0％ in the control group, and the difference was statistically significant (P<0.05). The VAS score and CMS changed notably after treatment in both groups (P<0.05), and the improvements were markedly greater in the treatment group than in the control group (P<0.05). Conclusion: Tendon-regulating and stretching manipulation plus JIN's three-needle therapy for the shoulder can facilitate the relief of pain and the improvement of shoulder joint function in SIS patients.
ABSTRACT
Arthroscopic treatment of ankle impingement syndrome (AIS) is a minimally invasive surgical procedure used to address symptoms caused by impingement in the ankle joint. This syndrome occurs when there is abnormal contact between certain bones or soft tissues in the ankle, leading to pain, swelling, or limited range of motion. Traditionally, open surgery was the standard approach for treating AIS. However, with advancements in technology and surgical techniques, arthroscopic treatment has become a preferred method for many patients and surgeons. With improved visualization and precise treatment of the arthroscopy, patients can experience reduced pain and improved functionality, allowing them to return to their daily activities sooner. In this paper, we reviewed the application and clinical efficacy the of arthroscopic approach for treating AIS, hoping to provide a reference for its future promotion.

Objective:To investigate the efficacy of total ankle arthroscopy for resection of the talus os trigonum and debridement of the synovium of flexor hallucis longus (FHL) in the treatment of osteogenic posterior ankle impingement syndrome (PAIS) complicated with flexor hallucis longus tenosynovitis (FHLT).Methods:The 14 patients with osteogenic PAIS and FHLT were retrospectively analyzed who had been treated at Department of Hand-Foot-Ankle Microsurgery, Xuzhou Central Hospital from July 2017 to July 2019. They were 8 men and 6 women, aged from 29 to 53 years (mean, 42.4 years). The talus os trigonum and the giant posterolateral process of the talus were resected under total ankle arthroscopy in the prone position of the posterior ankle while the FHL was released and cleared. The efficacy was evaluated by comparing the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, Maryland functional score, and pain visual analog scale (VAS) between preoperation and one year postoperation.Results:All patients were followed up for 12 to 24 months (average, 15 months). For all patients, their plantar flexion and dorsal extension were improved significantly from preoperative 19.2°±4.0° and 14.2°±2.7° to postoperative 42.9°±2.7° and 24.5°±3.2°, their AOFAS score increased significantly from preoperative 42.1±4.2 to 91.6±2.7 at one year postoperation, their Maryland score increased significantly from preoperative 43.9±4.1 to 91.9±3.5 at one year postoperation, and their VAS score decreased significantly from preoperative 6 (6, 7) to 0 (0, 0) at one year postoperation (all P<0.05). Conclusion:In the treatment of osteogenic PAIS complicated with FHLT, total ankle arthroscopy for resection of the talus os trigonum and release of FHL can lead to fine efficacy and limited surgical invasion, resolving the FHL pathological inflammation and PAIS at the same time.
ABSTRACT
Objective:To compare and analyze the value of X-ray examination and MRI in the diagnosis of subacromial impingement syndrome.Methods:Sixty patients with shoulder pain and weakness in Beijing Tiantan Hospital, Capital Medical University from January 2019 to May 2021 were selected. All patients underwent X-ray and MRI. Taking clinical diagnosis as the gold standard, the diagnostic efficacy of X-ray and MRI in subacromial impact syndrome was compared and analyzed.Results:The consistency between MRI and gold standard was good ( Kappa = 0.769, P<0.01), and the consistency between X-ray and gold standard was general ( Kappa = 0.464, P<0.01); there was no significant difference between X-ray examination and MRI examination of acromion morphological classification, subacromial space classification ( P>0.05); The sensitivity of MRI was higher than that of X-ray, and the difference was statistically significant ( χ2 = 4.00, P<0.05). There was no difference between MRI and X-ray, and the difference was not statistically significant ( χ2 = 0.25, P>0.05). Conclusions:X-ray and MRI are complementary to each other in the diagnosis of subacromial impingement syndrome. X-ray examination should be carried out first, and MRI should be carried out when necessary.
ABSTRACT
@#Introduction: Bigliani classification is used for determination of acromial morphology, but poor interobserver reliability has been reported on conventional radiographs. This study aims to assess inter- and intraobserver reliability using magnetic resonance imaging (MRI). Materials and methods: Forty consecutive patients diagnosed with subacromial impingement syndrome were included to study. All subjects underwent standard shoulder MRI scan and acromial shape was evaluated by nine observers of different level of expertise (three attending surgeons, three senior orthopaedic residents and three radiologists). A second set of evaluation was performed in order to assess intra-observer reproducibility. Kappa (κ) coefficient analyses both for interobserver reliability and intra-observer reproducibility were then performed. Results: Overall inter-observer agreement among nine observers was fair (κ=0.323). κ values for all 4 individual types ranged from 0.234 to 0.720 with highest agreement for type 4 and lowest agreement for type 3. Second evaluation did not result with an increase of inter-observer agreement (κ=0.338, fair). The κ coefficients for intra-observer reproducibility of nine observers ranged from 0.496 to 0.867. Overall intra-observer reproducibility was substantial. Comparison of inter- and intra-observer reliability among three groups showed no significant difference (p=0.92 and 0.22, respectively). Conclusion: Results showed that MRI did not show superior reliability compared to conventional radiographs. Moreover, inter- and intra-observer agreement did not differ between observers of different level of expertise. Findings of present study suggest that despite a sophisticated imaging modality like MRI, Bigliani’s classification apparently lacks accuracy and additional criteria, or different assessment methods are required to assess acromial morphology for clinical guidance.
ABSTRACT
Introduction: curved and hooked acromia play a key role in shoulder impingement syndrome. Little is known about acromial type in the Brazilian population. Aim: To describe the acromial profile of Brazilian young adults; to evaluate its correlation with gender and handedness and the occurrence of symmetry between the genders. Methodology: forty acromia in 20 Brazilian adults of both genders, aged 21-25 years, were studied. The acromial type was classified through the Bigliani/Epstein method using radiographs in supraspinatus outlet view. Results: as there was no gender difference in occurrences of acromial type, we considered the male and female groups together. Thus, among the 20 right acromia, we found 5 type I (25%), 8 type II (40%) and 7 type III (35%). Among the 20 left acromia, we found 4 type I (20%), 11 type II (55%) and 5 type III (25%). The only left-handed volunteer (100%) presented acromial type III in both the right and the left shoulder. Among the 19 right-handed volunteers, 5 (26.3%) presented right acromion type I, 8 (42.1%) had type II and 6 (31.6%) had type III; for the left acromion, 4 (21.1%) presented type I, 11 (57.9%) had type II and 4 (21.1%) had type III. Acromial symmetry occurred in 60% of females and 70% of males. Conclusion: type II acromion was predominant, in both the right and the left shoulder in Brazilian young adults. There was no correlation between acromial type and gender. It was not possible to analyze the correlation between acromial type and handedness. Acromial type tended to be symmetrical in our sample.
Introdução: o acrômio curvo e gancho desempenham um papel fundamental na Síndrome do impacto do ombro. Pouco se sabe sobre o tipo acromial na população brasileira. Objetivo: descrever o perfil do tipo acromial em adultos jovens brasileiros e avaliar sua correlação com o gênero e a lateralidade e a ocorrência de simetria entre os sexos. Metodologia: foram estudados 40 acrômios de 20 adultos brasileiros, de ambos os sexos, com idade entre 21 e 25 anos. O tipo acromial foi classificado pelo método de Bigliani/ Epstein nas radiografias de perfil de escápula. Resultados: como não houve diferença na ocorrência do tipo acromial quanto ao gênero, consideramos os grupos masculino e feminino juntos. Assim, dos 20 acrômios direitos, foram encontrados 5 (25%) do tipo I, 8 (40%) do tipo II e 7 (35%) do tipo III, enquanto que dos 20 acrômios esquerdos, foram encontrados 4 (20%) tipo I, 11 (55%) tipo II e 5 (25%) tipo III. O único voluntário canhoto (100%) apresentou para o ombro direito e esquerdo o tipo acromial III. Dos 19 voluntários destros, 5 (26,3%) apresentavam acrômio direito tipo I, 8 (42,1%) tipo II e 6 (31,6%) tipo III; para o acrômio esquerdo, 4 (21,1%) apresentavam tipo I, 11 (57,9%) tipo II e 4 (21,1%) tipo III. A simetria acromial ocorreu nos grupos feminino (60%) e masculino (70%). Conclusão: o acrômio tipo II foi o mais predominante para os ombros direito e esquerdo em adultos jovens brasileiros. Não houve correlação entre o tipo de acromial e o gênero. Não foi possível analisar a correlação entre o tipo acromial e a lateralidade. O tipo acromial tende a ser simétrico em na amostra estudada.

Background: Morphometric analysis of the acromion process is important in shoulder joint pathologies and the structures passing through the subacromion space or structures present underneath the coracoacromial arch are more prone to undergo impingement and end with impingement syndrome of the shoulder joint. Knowledge on the morphometry of the acromion process is essential before planning surgical treatment of the impingement syndrome such as, acromioplasty or acromionectomy. The present study is aimed to focus on the morphometric analysis of the acromion process. Subjects and Methods: The present study was carried on 100 dry adult scapulae in which 50 were right and 50 were left. The following parameters were measured; length of the acromion, width of the acromion, coracoacromial distance and the acromioglenoidal distance. All the parameters were measured using vernier caliper. Results: The mean length of the acromion process was 42.55mm and 41.43mm on the right and the left sides respectively. The mean width of the acromion process was 23.12mm and 22.8mm on the right and the left sides respectively. The mean coracoacromial distance was 34.16mm and 34.15mm on the right and the left sides respectively. The average acromioglenoid distance was 24.48mm and 24.52mm on the right and the left sides respectively. Conclusion: The morphometric data of this study will be of great importance for the orthopaedic surgeon while treating the impingement syndrome and other surgeries of shoulder joint.
ABSTRACT
Objective:To investigate the correlations between subacromial impingement syndrome (SIS) and acromial morphology and subacromial intervals after surgery of proximal humerus fracture.Methods:A retrospective study was conducted of the 62 patients with proximal humerus fracture who had been treated by internal fixation with a locking titanium plate from December 2014 to December 2019 at Department of Orthopedics, People's Hospital of Gaoming District. They were 40 men and 22 women, with an average age of 53.5 years (from 35 to 71 years). By the Neer classification, there were 38 three-part and 24 four-part fractures. The incidence of SIS was determined by Nikolaus's diagnostic criteria. The patients were divided into a SIS group and a non-SIS group. The acromial morphology was observed and the subacromial intervals [acromio-greater tuberosity of humerus interval (AGI) and acromio-plate interval (API)] were measured on postoperative X-ray films. The correlations were analyzed between them and SIS.Results:All patients completed treatments and follow-ups from 3 to 15 months (average, 10 months). There was no incision infection or internal fixation failure. There were 18 cases in the SIS group and 44 ones in the non-SIS group. In the SIS group, 3 cases had type Ⅰ acromion while 15 ones type Ⅱ or type Ⅲ acromion; in the non-SIS group, 20 cases had type Ⅰ acromion while 24 ones type Ⅱ or type Ⅲ acromion. The proportion of patients with type Ⅱ or type Ⅲ acromion in the SIS group was significantly higher than that in the non-SIS group ( P<0.05). AGI and API in the SIS group were (11.6±2.1) mm and (14.2±2.4) mm, significantly shorter than those in the non-SIS group [(15.7±2.8) mm and (18.5±3.2) mm] ( P<0.05). Conclusions:SIS is a common complication after surgery of proximal humerus fracture. Abnormal acromial morphology (type Ⅱ or type Ⅲ acromion), poor fracture reduction (reduced AGI), and high placement of a titanium plate (reduced API) may be all important factors leading to SIS.
ABSTRACT
ABSTRACT BACKGROUND AND OBJECTIVES: The subacromial impingement syndrome is a dysfunction of the glenohumeral joint which can cause pain, functional disability, dependence, and low quality of life. The aim of this study was to compare the muscle strength between painful and non-painful shoulders and to verify the relationship between shoulder pain and disability and isometric muscle strength of the upper limb and kinesiophobia level in individuals with symptoms of subacromial impingement syndrome. METHODS: Twenty volunteers with symptoms of subacromial impingement syndrome participated in the study. The evaluation was carried out by means of an evaluation form, the Shoulder Pain and Disability Index questionnaire (SPADI - BRAZIL) to assess disability and shoulder pain and the TAMPA questionnaire to analyze the level of kinesiophobia. The evaluation of shoulder isometric muscle strength was performed using the Manual Hand-Held Dynamometer stabilized by a rigid band in the movements of flexion, extension, abduction and internal and external rotation of the shoulder. RESULTS: In the comparison of muscle strength between symptomatic and asymptomatic side, evidence of significant difference (p<0.05) was verified for all movements evaluated. There was a significant negative relationship between shoulder pain and disability index and isometric muscle strength of flexion and internal rotation, and a significant positive relationship with the level of kinesiophobia. CONCLUSION: Individuals with symptoms of subacromial impingement syndrome showed a significant reduction in muscle strength of the symptomatic shoulder. The shoulder pain and disability index is related to the isometric muscle strength of the shoulder and to the level of kinesiophobia.

ABSTRACT
Abstract Objective: To evaluate the effect of acromial inferolateral tilt on subacromial impingement syndrome. Materials and Methods: The acromial inferolateral tilt was retrospectively quantified by two researchers on 346 shoulder magnetic resonance images using the glenoacromial (between the inferior proximal acromial surface and the glenoidal face) and acromioclavicular (between the axis of the proximal acromion and distal clavicle) angles. Results: The glenoacromial angle was associated with subacromial impingement syndrome (p < 0.001) and complete supraspinatus tendon rupture (p < 0.001), and the acromioclavicular angle was associated with partial or complete supraspinatus tendon rupture (p = 0.003). The area under the receiver operating characteristic curve (AUC), best cut-off angle, and odds ratio (OR) of the glenoacromial angle for impingement syndrome were 0.579 (95% confidence interval [CI]: 0.508-0.649; p = 0.032), 72°, and 2.1 (95% CI: 1.136-4.053), respectively. For complete supraspinatus tendon rupture, the AUC, best cut-off angle, and OR of the glenoacromial angle were 0.731 (95% CI: 0.626-0.837; p = 0.001), 69°, and 8.496 (95% CI: 2.883-28.33), respectively. For partial or complete supraspinatus tendon rupture, the AUC, best cut-off angle and OR of the acromioclavicular angle were 0.617 (95% CI: 0.539-0.694; p = 0.002), 17°, and 3.288 (95% CI: 1.886-5.768), respectively. Interobserver agreement found for the glenoacromial and acromioclavicular angles were 0.737 (95% CI: 0.676-0.787; p < 0.001) and 0.507 (95% CI: 0.391-0.601; p = 0.001), respectively. Conclusion: Inferolateral acromial tilt may have some impact on subacromial impingement syndrome; however, the best quantification method identified (glenoacromial angle) showed a moderate interobserver agreement and a fair performance to assess the risk of complete supraspinatus tendon rupture.
Resumo Objetivo: Avaliar a contribuição da inclinação inferolateral do acrômio na síndrome do impacto subacromial. Materiais e Métodos: A inclinação inferolateral do acrômio foi quantificada retrospectivamente por dois pesquisadores em 346 ressonâncias magnéticas de ombro por meio dos ângulos glenoacromial (entre a superfície inferior proximal do acrômio e a face glenoidal no plano coronal) e acromioclavicular (entre o eixo do acrômio proximal e o eixo da clavícula distal no plano coronal). Resultados: Houve associação entre ângulo glenoacromial e síndrome do impacto subacromial (p < 0,001) e ruptura completa do tendão supraespinal (p < 0,001). Ângulo acromioclavicular associou-se a ruptura parcial ou completa do tendão supraespinal (p = 0,003). A área sob a curva (area under the curve - AUC) característica de operação do receptor, o melhor ângulo de corte e a razão de chances (odds ratio - OR) do ângulo glenoacromial para a síndrome do impacto foram, respectivamente: 0,579 (intervalo de confiança [IC] 95%: 0,508-0,649; p = 0,032), 72° e 2,1 (IC 95%: 1,136-4,053). Para ruptura completa do tendão supraespinal, a AUC, o melhor ângulo de corte e a OR do ângulo glenoacromial foram, respectivamente: 0,731 (IC 95%: 0,626-0,837; p = 0.001), 69° e 8,496 (IC 95%: 2,883-28,33). Para ruptura parcial ou completa do tendão supraespinal, a AUC, o melhor ângulo de corte e a OR do ângulo acromioclavicular foram, respectivamente: 0,617 (IC 95%: 0,539-0,694; p = 0,002), 17° e 3,288 (IC 95%: 1,886-5,768). As concordâncias interobservador encontradas para os ângulos glenoacromial e acromioclavicular foram, respectivamente: 0,737 (IC 95%: 0,676-0,787; p < 0,001) e 0,507 (IC 95%: 0,391-0,601; p = 0,001). Conclusão: Inclinação inferolateral do acrômio pode determinar alguma influência sobre a síndrome do impacto subacromial, entretanto, o melhor método de quantificação identificado (o ângulo glenoacromial) apresentou moderada concordância interobservador e desempenho moderado para estratificar o risco de ruptura completa do tendão supraespinal.
ABSTRACT
BACKGROUND: Metal anchors are not easily accepted by patients as permanent foreign bodies, so bioabsorbable anchors have been gradually applied in orthopedics in recent years. OBJECTIVE: To evaluate the effectiveness of absorbable suture anchors for repairing femoroacetabular impingement syndrome combined with acetabular labral tears. METHODS: Eighty patients with femoroacetabular impingement syndrome combined with acetabular labral tears admitted in Beijing Shijitan Hospital Affiliated to Capital Medical University from February 2014 to February 2016 were selected, and all were treated by absorbable suture anchors under arthroscopy. The Harris hip score, and the Visual Analogue Scale score at baseline, postoperative 1 and 3 months were recorded and compared to assess the effectiveness. The complications and material-host reaction were recorded. The treatment satisfaction was evaluated. The study was approved by the Ethical Committee of Beijing Shijitan Hospital and all patients and their families signed the informed consents. RESULTS AND CONCLUSION: (1) The Harris hip scores at 1 and 3 years postoperatively in 80 patients with femoroacetabular impingement syndrome combined with acetabular labral tears were significantly higher than those at baseline, and the Visual Analogue Scale scores were significantly lower than those at baseline (P 0. 05). (3) None appeared with anchor drop off, cartilage injury or material-host reaction. In summary, the method of absorbable suture anchors under arthroscopy has the advantages of minimal invasion, reliable fixation, simple operation, no metal implants, and significant clinical effect to treat femoroacetabular impingement syndrome combined with acetabular labral tears.
ABSTRACT
Abstract Objective This research aims to study the effectiveness of platelet-rich plasma (PRP) in the treatment of patients with rotator cuff impingement syndrome compared with the treatment with subacromial injection of corticosteroids. Methods This is a double-blind, randomized, comparative clinical trial. The patients were clinically evaluated with the use of the Disabilities of the Arm, Shoulder and Hand (DASH) outcome measure, University of California Los Angeles (UCLA) shoulder rating scale and Constant-Murley shoulder outcome score (CMS) on the day of application, and then again after 1, 3 and 6 months. Results No statistically significant differences were found (p < 0.05) when comparing the results of the DASH outcome measure, UCLA shoulder rating scale and CMS of the two groups at baseline and after 1, 3, and 6 months of treatment with subacromial injection. After the treatment, both groups showed a significant improvement in the DASH and UCLA scores (p < 0.05) when compared with the baseline. However, the CMS at 6 months after treatment with steroids was lower than the baseline. Concusions These findings suggest that PRP is a safe treatment and can be a useful tool in the therapeutic arsenal against of the rotator cuff diseases, for there was no significant difference between the subacromial use of PRP and corticosteroids.
Resumo Objetivo Analisar a eficácia do uso de plasma rico em plaquetas (PRP) no tratamento de pacientes portadores de síndrome de impacto do manguito rotador em comparação ao tratamento com injeção subacromial de corticosteroides. Métodos O estudo é de caráter comparativo, longitudinal, duplo cego e randomizado. A evolução clínica dos pacientes foi quantificada pelas escalas The Disabilities of the Arm, Shoulder and Hand (DASH) outcome measure, University of California Los Angeles (UCLA) shoulder rating scale e Constant-Murley shoulder outcome score (CMS) no dia da aplicação, e novamente após 1, 3, e 6 meses. Resultados Não foram encontradas diferenças etsatisticamente significativas (p< 0.05) ao comparar os resultados do DASH outcome measure, UCLA shoulder rating scale, e CMS dos dois grupos na admissão. Após o tratamento, ambos os grupos apresentaram melhora significativa tanto do DASH, quanto do UCLA (p< 0,05). Entretanto, o escore do CMS referente ao tratamento com corticoide mostrou-se pior no 6° mês em comparação com o escore à admissão. Conclusão Esses achados sugerem que o PRP é um tratamento seguro e que pode ser uma ferramenta útil no arsenal terapêutico contra doenças do manguito rotador, uma vez que não foram encontradas diferenças significativas entre os grupos que receberam PRP e injeção subacromial de corticosteroides.

Background: Shoulder Impingement Syndrome (SIS) is a major contributing factor for shoulder pain. Although many therapists use Kinesio Taping (KT) and Manual Therapy (MT) for SIS, no such studies in combination with Supervised Exercise Therapy (SET) have been conducted in the context of Saudi Arabia. Thus, the purpose of this study is to compare the effectiveness of KT and MT with SET in patients with SIS. Methods: Randomized controlled trial. Thirty-two subjects were assigned into two groups (KT with SET and MT with SET). The following outcome measures were measured at baseline, three weeks and six weeks. The outcome measurements are pain intensity by a numerical pain rating scale (NPRS), Active range of motion in the shoulder (AROM) by goniometry, and the functions of the shoulder measured through Shoulder Pain and Disability Index (SPADI). A simple descriptive statistical analysis was adopted to describe the patient-specific demographic characteristics with respect to outcome parameters. Within-group and between groups comparison were analyzed using ANOVA, and Scheffes’ posthoc tests by using SPSS 21.0. Results: Sixteen subjects completed treatment in each group. No differences were identified between groups at baseline. In ANOVA, it was shown that both groups significantly (p<0.05) decreased pain intensity, improved function and increased shoulder AROM in the 3rd week, and 6th week. However, post hoc analysis results suggested that the KT, in conjunction with SET, had a higher proportion of change on 3rd week, of the pain intensity, SPADI, and AROM. Conclusion: KT with SET has been found to be more effective than the MT with SET in the 3rd week and had the same effect in the 6th week of the treatment. When an immediate effect is expected, KT may be a better choice of treatment in the management of SIS.
ABSTRACT
ABSTRACT Background: Many causes can lead to shoulder pain and subacromial impingement syndrome (SIS) is the most frequently recorded disorders. The aim of this study was to evaluate the clinical effects of diminutive incision acromioplasty assisted with arthroscopy for the treatment of Chinese patients with subacromial impingement syndrome. Subject and Methods: Twenty-two patients with 24-painful shoulders subacromial impingement syndrome were enrolled. All painful shoulders were in Grades II (8) and III (16) according to Neer's classification. Detailed physical examination was performed. Conventional radiography and subsequent magnetic resonance imaging (MRI) of the shoulder region of all patients were done. The University of California at Los Angeles Shoulder (UCLA) score system was used for all patients to evaluate their satisfaction after surgery. The preoperative recordings of the UCLA scores were collected and all enrolled cases including 24-painful shoulders were available for follow-up in 1, 3, 6, 12 months after surgery. Results: According to the UCLA scoring system, the symptom of all painful shoulders were improved after one year postoperatively. The average score before surgery from 15.4 points increased to 31.2 points postoperatively, showing a statistical difference (p < 0.05). Conclusions: A diminutive incision acromioplasty assisted with arthroscopy is a reliable approach to treat Chinese patients with subacromial impingement syndrome. All painful shoulders were obviously improved in one year after surgery.

Background: Alteration in upper body posture is associated with shoulder impingement due to changes in scapular orientation, increased thoracic kyphosis and concomitant imbalance of glenohumeral and scapulothoracic muscles. Mechanical correction of scaular and thoracic posture can reduce impingement. Recently use of kinesiotapes has been increasingly popular. There have been some studies reporting the effect of kinesiotapes on muscle activation and pain reduction in subacromial impingement syndrome. Kinesiotapes can also be used to correct scapular and thoracic posture in Subacromial Impingement Syndrome. Purpose of study: To study the effect of scapula and thoracic taping using kinesiotapes in addition of conventional treatment on scapular posture and shoulder range of motion in Subacromial Impingement Syndrome. Materials and Methods: 60 subjects with Subacromial Impingement Syndrome were randomly assigned to two groups. Experimental group received scapula and thoracic taping using kinesiotape for 24hrs along with conventional physiotherapy treatment. Control group received conventional physiotherapy. Subjects were assessed pre, immediate post intervention and 24hr post intervention for scapular posture, shoulder range of motion and pain. Results: Experimental group showed statistical significant improvement(p<0.001) in scapular posture, shoulder range of motion and pain (on medial rotation, and reaching the back) scores both immediately and 24hour post intervention compared to control group. Also greater improvement was seen in pain and range of motion post 24 hour as compared to immediate post intervention in experimental group. Conclusion: Taping as an adjunct to conventional treatment is much more effective for short term improvement in scapular postures, range of motion and reduction in pain as compared to only conventional treatment in subjects with Subacromial Impingement Syndrome.
ABSTRACT
Objective To provide anatomic evidence for chock-block technique used for acromioplasty.Methods Thirty cadaveric specimens of intact shoulder fixed by formaldehyde solution were used for this anatomic study.They were chosen from 15 males and 15 females and from 17 left and 13 right sides.First the specimens were dissected for observation of general morphology of the acromion.According to the Bigliani's classification,the acromions were sorted in morphology as type Ⅰ (flat),type Ⅱ (curved) and type Ⅲ (hooked).The shortest distance from the acromion to the humeral head (A-H) was measured.Then the location of subacromial impingement was observed and the thickness of the anterolateral angle was measured preoperatively.At last,acromioplasty using the chock-block technique was performed in the acromions of types Ⅱ and Ⅲ.Postoperatively,the distance A-H and the thickness of the anterolateral angle were measured again for comparison with the preoperative values.Results According to the Bigliani's classification,7 acromions were type Ⅰ,13 type Ⅱ and 10 type Ⅲ.Subacromial impact occurred only in the anterior acromions of types Ⅱ and Ⅲ.The distance A-H was 0.670 ± 0.035 cm in type Ⅰ acromions,significantly longer than the preoperative values of type Ⅱ (0.506 ±0.029 cm) and type Ⅲ (0.334 ±0.023 cm) (P ＜ 0.05),but showed no significant differences from the postoperative values of type Ⅱ (0.692 ±0.025 cm) and type Ⅲ (0.699 ±0.024 cm) (P ＞ 0.05).The anterolateral angular thickness of type Ⅰ acromions was O.413 ± 0.015 cm,significantly thinner than the preoperative values of type Ⅱ (0.607 ±0.014 cm) and type Ⅲ (0.623 ±0.025 cm) (P ＜ 0.05),but showed no significant differences from the postoperative values of type Ⅱ (0.414±0.035 cm) and type Ⅲ (0.412±0.033 cm) (P＞ 0.05).Conclusion The chock-block technique used for acromioplasty is effective because it can enlarge the supraspinatus outlet and deter impingement.
ABSTRACT
Objective:To study the effect of weight relief raise on acromiohumeral distance in patients with thoracolumbar spinal cord injury. Methods:The acromiohumeral distance of 20 patients with thoracolumbar spinal cord injury was measured by ultrasonic diagnostic system, respectively in the resting position and the supporting decompression position. Results:The acromiohumeral distance was significantly larger in the resting position than in the supporting decompression position (t = 6.933, P < 0.001). Conclusion:Support could reduce the subacromial space in patients with spinal cord injury and become a potential factor for subacromial tissue injury.
