[PMID: 36683027 PMCID: PMC9869551 DOI: 10.1186/s12891-023-06152-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/19/2022] [Accepted: 01/09/2023] [Indexed: 01/24/2023] Open
Abstract
BACKGROUND Differentiation between subacromial impingement versus subcoracoid impingement are important for the treatment target. We evaluated the correlations between coracohumeral ligament (CHL) thickness and distance (CHD) and characterized the CHL and subscapularis (SSC) in subcoracoid impingement subjects. METHODS An observational, cross-sectional study was carried out. Twenty subcoracoid impingement subjects and age/gender matched controls were assessed in 4 different shoulder positions by ultrasonography. RESULTS Moderate correlations between CHL thickness with CHD (r = 0.455 in neutral rotation, p = 0.044; r = 0.483 in interior rotation, p = 0.031) were found in subacromial subjects. Subcoracoid impingement subjects had greater CHL thickness (difference = 0.3 mm, effect size = 0.85, p = 0.006), SSC tendon thickness (difference = 0.7 mm, effect size = 0.92, p = 0.01) and SSC/CHD occupation ratio (difference = 8%, effect size = 0.95, p = 0.005) compared with the control. CONCLUSIONS Coracohumeral distance is related to ligament thickness, especially in subacromial impingement subjects. Increased coracohumeral ligament and subscapularis thickness as well as decreased subscapularis/coracohumeral distance occupation ratio are characterized in subcoracoid impingement subjects. These quantitative measurements can be useful in identifying patients at risk of subcoracoid impingement from subacromial impingement.

Abstract
BACKGROUND: The occurrence of subacromial pain syndrome (SPS) is associated with the frequent handling and lifting of heavy loads and excessive repetitive work. Thus, assembly workers have a high prevalence of SPS. OBJECTIVE: The purpose of this study was to investigate differences in shoulder ROM, muscle strength, asymmetry ratio, function, productivity, and depression between workers with and without SPS. METHODS: Sixty-seven male workers (35 workers with SPS and 32 workers without SPS) participated in this study. Shoulder internal rotation (SIR), shoulder external rotation (SER), shoulder abduction (SAB), shoulder horizontal adduction ROM and SIR, SER, elbow flexion (EF), scapular depression and adduction, scapular protraction strength were measured. The asymmetry ratio was calculated using the asymmetry ratio formula; shoulder functions were measured using the shoulder pain and disability index (SPADI), disabilities of the arm, shoulder, and hand (DASH), and visual analogue scale (VAS); and Endicott work productivity scale (EWPS). RESULTS: The SPADI (p = 0.001), DASH (p = 0.001), and VAS (p = 0.001) values of workers with SPS were higher than those of workers without SPS. Also, workers with SPS had lower SIR (p = 0.001) and SAB (p = 0.002) ROM compared to workers without SPS. In addition, workers with SPS exhibited lower SIR (p = 0.012) strength than workers without SPS. Workers with SPS had higher asymmetry ratio in SIR (p = 0.015), SER (p = 0.005), and EF (p = 0.008) strength than workers without SPS. CONCLUSIONS: The SIR, SAB ROM, SIR strength, and the asymmetry ratio of SIR, SER, EF strengths could provide an important baseline comparison for the workers with SPS.

Differences in Coracohumeral Distance Between the Symptomatic and the Asymptomatic Shoulder in Patients With Unilateral Shoulder Pain and in Healthy Participants: A Cross-Sectional Study. J Manipulative Physiol Ther 2022; 45:515-521. [PMID: 36517268 DOI: 10.1016/j.jmpt.2022.10.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2022] [Revised: 10/02/2022] [Accepted: 10/13/2022] [Indexed: 12/15/2022]
Abstract
OBJECTIVES The aim of this study was to analyze whether differences in the coracohumeral distance (CHD) exist between the symptomatic and the asymptomatic shoulder in patients with subacromial pain syndrome and compare with the shoulder of control participants. METHODS This was a cross-sectional, observational study. A sample comprising 62 participants with subacromial pain syndrome was recruited from 3 different primary care centers. The CHD was determined from standardized ultrasonography measures performed on both shoulders at 0° and 60° of shoulder abduction, whereas the dominant arm was measured for the control participants. RESULTS Statistically significant differences in CHD at 0° and 60° were found between the symptomatic and control shoulders (P = .011/P = .002) and between the contralateral asymptomatic shoulder and controls (P = .026/P = .007). CONCLUSION We found differences in CHD at 0° and 60° of shoulder elevation between both the affected and the nonaffected shoulders when compared with healthy shoulders. These results suggest that CHD may be a contributing factor in chronic shoulder pain.

Abstract
Cystic lesions of the humeral head are commonly encountered on routine shoulder magnetic resonance imaging (MRI). Differential diagnoses include degenerative lesions, calcific tendinitis with osseous involvement, perianchor cysts, abscesses and less often, tumours. Degenerative lesions, including subcortical and subchondral cysts, are the most commonly encountered. These may be associated with rotator cuff disease and degenerative joint diseases or considered part of ageing depending on the location of the cystic lesions. For instance, cysts of the bare area of the humeral head are considered benign age-related entities, whereas cysts of the greater or lesser tuberosity may herald rotator cuff disease. Infectious lesions, particularly osteomyelitis and intraosseous (Brodie’s) abscesses, are intramedullary in location and should be suspected in the context of clinical features such as fever and radiological features such as the penumbra sign. Perianchor cysts are postoperative lesions associated with the use of suture anchors in surgeries such as rotator cuff tear repairs. They generally self-resolve over 18 to 24 months. On MRI, the distribution, morphology, and signal characteristics can help point towards a specific diagnosis. The patient’s demographic, clinical presentation, and past surgical history can be discriminatory. Knowledge of different cystic lesions in the humeral head and underlying aetiology can be useful in helping the radiologist develop a more thorough search pattern for associated conditions. Determining the underlying cause of cysts can have important implications on management, such as when differentiating perianchor cysts from infection. This pictorial review outlines the differential diagnoses of humeral head cysts on MRI and provides a diagnostic approach for the radiologist.

Abstract
Abstract
Modifications in joint anatomy on both soft and bony tissue level play a key role in subcoracoid impingement syndrome. The diagnostic is primarily clinical and is based on patient history and functional tests. Imaging tests support, but do not establish the diagnostic. Approach can take the form of targeted exercises with progressive load, or that of invasive surgery.
Shoulder pain has a diverse etiology which derives from the complex local anatomy which includes the clavicle, acromion, coracoid process and humeral head, the soft tissues surrounding this area, in particular the rotator cuff, but can also be unrelated to all of the above and be a reflection of a pathology located in the neck, arm or trunk, or adjacent visceral organs. More often, it is the manifestation of a traumatic episode or an anatomical anomaly, or it can be secondary to inflammation, tumors, or surgery.
It is the third most common musculoskeletal complaint presenting to physiotherapy, and largely impacts both an individual’s quality of life and the public health system.
Coracoid impingement syndrome can present itself as a cause of rotator cuff disease, but its role is not fully established yet. It is less prevalent than subacromial impingement, can coexist with it, and therefore should be considered into the differential diagnosis of anterior shoulder pain when a patient presents themselves with activity related anterior shoulder pain.

Abstract
BACKGROUND The observation of the roller-wringer effect fueled the idea that coracoid morphology is related to subscapularis pathology. We aimed to examine this relationship, specifically focusing on how the coracohumeral distance (CHD) and 2 new metrics of coracoid morphology relate to subscapularis tears. METHODS In this retrospective study, we identified consecutive patients 45 years or older who underwent shoulder arthroscopy for any indication. We blindly reviewed preoperative magnetic resonance imaging studies of each patient, measuring the CHD, lateral extent (LE), and caudal extent (CE) of the coracoid process. Patients' subscapularis condition was assessed via operative reports; stratified according to Lafosse grade criteria; and compared for differences in the CHD, LE, and CE by 1-way analysis of variance and 2-tailed t tests. RESULTS The study included 201 patients. Of these, 112 had no evidence of subscapularis injury, whereas Lafosse grade I injuries were identified in 52 patients; grade II, in 19; and grades III-V, in 18. The CHD, LE, and CE were not correlated with subscapularis injury (CHD, P = .36; LE, P = .36; and CE, P = .13). CONCLUSIONS We found no correlation between subscapularis injury and the CHD, LE, and CE. These findings support the idea that coracoid morphology may not be a cause of subscapularis pathology and suggest that coracoplasty may not be necessary prophylactically or as part of subscapularis repair.

Abstract
PURPOSE The acromial and coracoid process morphology is of clinical relevance due to associations with functional limitations and shoulder pathology. Our objective was to describe the anatomical characteristics of the acromial and coracoid process using computed tomography (CT). METHODS Descriptive, observational, transversal and retrospective study. A total of 155 CT of patients without shoulder pathology, of both genders, and indistinct age were evaluated and grouped by age: Group 1 < 25 years; group 2 25-40 years; group 3 > 40 years. The following parameters were evaluated: Acromial type (AcT), vertical coracoid distance (VCD), acromial tilt (AT), acromial projection (AP), critical shoulder angle (CSA), type of the subcoracoid outlet (TSO), and the area of the subcoracoid outlet (ASO). RESULTS Statistically significant differences were found between men and women for VCD (14.44 ± 4.79 vs. 11.76 ± 4.00 mm; p < 0.001) and AP (3.66 ± 4.71 vs. 1.62 ± 4.99 mm; p < 0.05) as well as between age groups 1 and 3 for AT (35.08 ± 11.53 vs. 28.41 ± 6.60; p < 0.05) and ASO (398.99 ± 153.91 vs. 255.56 ± 124.58 mm2; p < 0.001). An unexpected high ASO variation was identified with 11% of S-shaped acromion and 1.3% clock-shaped TSO. CONCLUSION The age group between 25-40 years had the most uniform distribution of data. There is a high morphological variability present in an asymptomatic population, which should be considered in the clinical assessment such as shoulder impingement syndrome.

Abstract
BACKGROUND The aim of this study was to investigate the effects of coracoid morphology, coracohumeral distance, coracoglenoid angle, and coracohumeral angle variabilities on subcoracoid impingement development using magnetic resonance imaging (MRI). MATERIAL AND METHODS A total of 200 patients (87 males with mean age of 51.1±15.2 years and 113 females with mean age of 52.6±10.7 years) undergoing shoulder MRI were included in this retrospective study. All MRI studies were performed with standard positioning. Coracoid morphology and subscapularis tendon were evaluated. Coracohumeral distance, coracoglenoid angle and coracohumeral angle were measured in all subjects. One-way ANOVA was used to assess the difference between the groups. For binary comparisons, Tukey post hoc analysis was done. Pearson correlation analysis was performed between variables. RESULTS Type C coracoid was more frequent in the tendinosis and tendon tear groups. There was a significant difference between type C coracoid and the other coracoid types for coracohumeral distance values (P=0.016). There was a statistically significant decrease in coracoglenoid angle values and coracohumeral distance in patients with subscapularis tendon pathologies (P=0.000). A statistically insignificant increase in coracohumeral angle values was found in the subscapularis tendon pathologies. There was a positive correlation between coracohumeral distance and coracoglenoid angle (R=0.749 P=0.000). There was a negative correlation between coracohumeral distance and coracohumeral angle (R=-0.668 P=0.000) and between coracoglenoid angle and coracohumeral angle (R=-0.605 P=0.000). CONCLUSIONS In subscapularis tendon pathologies, decrease in coracohumeral distance and coracoglenoid angle was observed. A new approach uses coracohumeral angle to evaluate subcoracoid impingement. A statistically insignificant increase in coracohumeral angle was noted.

Abstract
Shoulder arthroscopy in expert hands is now a tool for diagnosis and treatment. Diagnostic shoulder arthroscopy begins with a systematic review of the shoulder. This review should include the ramp test for confirming normal superior glenohumeral ligament (SGHL) integrity and function. The ramp test uses manipulation of the biceps tendon to achieve this. A negative ramp test finding means that the SGHL is intact and the biceps tendon moves freely down in a V-type pattern. A positive ramp test finding results when the biceps tendon subluxates through a failed SGHL and therefore presents with a U-shaped pattern indicating pathology. Intra-articular biceps tendon instability occurs due to SGHL tearing, which can lead to upper subscapularis rotator cuff partial tears or complete tears either acutely or over time.

Abstract
BACKGROUND The aim of this study was twofold: (i) to assess the intrarater reliability of coracohumeral distance; (ii) to investigate the level of association between coracohumeral distance measured by ultrasonography, and pain-disability and shoulder range of movement, in patients suffering from chronic anterior shoulder pain. METHODS An observational, cross sectional study was carried out. A convenience sample comprised of 87 patients with chronic anterior shoulder pain was assessed from 3 primary care centres. Main outcomes as pain and function were measured through the shoulder pain and disability index. Furthermore, shoulder range of movement-free of pain in shoulder elevation, as well as coracohumeral distance at both 0 and 60 degrees, were collected. RESULTS Absence of any correlation was found between coracohumeral distance and shoulder pain and disability index at both 0 and 60 degrees of shoulder elevation. Furthermore, absence of any correlation was found between coracohumeral distance measurements and active shoulder range of movement -free of pain. CONCLUSIONS There was poor association between coracohumeral distance and shoulder pain and function, as well as with shoulder range of movement, in patients with chronic anterior shoulder pain. Hence, clinicians should consider, not only increasing this space, but also other possibilities in their therapies, when patients with anterior shoulder pain are treated.

Abstract
PURPOSE Coracoid morphology has been related to coracoid impingement mainly resulting in anterior shoulder pain aggravated by forward flexion and internal rotation. However, the coracoid process morphology can also affect the inclination of the coracoacromial ligament and subsequently the subacromial space in the same way that acromial slope does. The purpose of this study was to evaluate the influence of the coracoid body-glenoid surface, coracoid tip-glenoid surface, and coracoid body-coracoid tip angles (coracoid inclination angles) on rotator cuff tears (RCTs). METHODS Fifty patients with documented RCT and 50 patients with normal rotator cuff (control) were included. The coracoid inclination angles were determined in both groups by measuring on computed tomography scans the angle created by the coracoid body and the glenoid surface (A1), the angle created by the coracoid tip and the glenoid surface (A2), and the angle created by the coracoid body and the coracoid tip (A3). RESULTS All angles were significantly lower in the RCT group compared to the control group: mean A1 angle of 49.7° and 54.61°, respectively ( p = 0.011); mean A2 angle of 76.45° and 93.6°, respectively ( p < 0.001); and mean A3 angle of 132.33° and 144.34°, respectively ( p < 0.001). CONCLUSIONS Decreased coracoid body-glenoid surface, coracoid tip-glenoid surface, and coracoid body-coracoid tip angles are associated with RCT. Decreased angles may reduce subacromial space by projecting the coracoacromial ligament more vertically.

Abstract
Introduction Coracoid impingement is considered a known yet frequently overlooked cause of anterior shoulder pain. Subcoracoid stenosis has been shown to be related to subscapularis tear. Studies have shown that patients with coracoid impingement have a shorter coracohumeral distance (CHD) and a larger coracoid overlap (CO) but these are based on data from Western populations. The aim of our study was to provide a local database on the MRI measurement of these parameters in our Chinese population and raise the awareness of this disease entity. Methods All the shoulder MRI films taken in our hospital in 2011 were retrospectively reviewed and classified into two cohorts. The control group consisted of patients who had no subscapularis lesion. The subscapularis lesion group consisted of patients with complete tear, partial tear or abnormal signal over the subscapularis tendon. The CHD and CO were measured. Results We reviewed 133 sets of shoulder MRI obtained in our hospital during 2011. Thirteen patients were noted to have subscapularis lesion. The CHD in the subscapularis lesion group was 6.24 ± 2.18 mm. The CHD in the control group was 9.95 ± 3.9 mm. Women had shorter CHD (8.18 ± 2.57 mm) than men (11.0 ± 4.54 mm). We failed to notice any statistically significant difference with regards to CO, coracoid process and lesser tuberosity morphology between the two groups of patients. Conclusion MRI assessment of CHD can be useful in identifying patients at risk of having subscapularis lesion and coracoids impingement.

Abstract
Subcoracoid impingement syndrome is a rare and underrecognized cause of anterior shoulder pain. Currently, subcoracoid impingement syndrome is understood to involve impingement of anatomic structures such as the subcoracoid bursa and subscapularis tendon within the coracohumeral space, and there are no reports of sonographic findings in subcoracoid impingement syndrome other than the impingement of thickened subscapularis bursa. Here we report a case of subcoracoid impingement syndrome, including a novel sonographic finding, arthroscopic findings, and a proposed pathophysiology. LEVEL OF EVIDENCE V.

Abstract
BACKGROUND The objective of this study was to provide preliminary measures of the distance between the supraspinatus, infraspinatus, and subscapularis footprints and the acromion, coracoacromial ligament, and coracoid process, during dynamic arm elevations through the entire range-of-motion. METHODS Two healthy men performed maximum adduction, flexion, abduction, and extension with the arm internally, neutrally, and externally rotated. The distance between each rotator cuff footprint and the acromion, coracoacromial ligament, and coracoid process was measured from glenohumeral kinematics obtained from markers fitted to intracortical pins combined with the scapular and humeral 3D geometry obtained from CT-scan. RESULTS All footprints moved to be less than 10 mm to the acromion, coracoacromial ligament and coracoid process. They got closer to the acromion than to the other parts of the coracoacromial arch. The acromion-supraspinatus and acromion-infraspinatus distances were minimal during abduction and flexion. The acromion-subscapularis distance was minimal when the arm was in external and neutral rotation during both adduction and flexion. CONCLUSIONS The present study provides benchmark results of the distance between the rotator cuff footprints and the coracoacromial arch that may guide future clinical research. Pressure transducers should be positioned throughout the coracoacromial arch to provide comprehensive assessment of the compression undergone by the rotator cuff tendons. Common shoulder examination tests, that require flexion and internal rotation movements, may be refined since the supraspinatus footprint was the closest to the coracoacromial arch during abduction. Larger scale investigations may be needed to identify more accurate shoulder examination tests.

Skeletal Radiol 2015; 44:1309-16.

Abstract
OBJECTIVE Orthopaedic surgical studies have shown that variations in the vertical distance between the tip of the coracoid process and the supra-glenoid tubercle alter the shape of the subcoracoid outlet. Our objective was to measure the vertical distance between the coracoid tip and the supra-glenoid tubercle (CTGT) on MR and to assess whether this showed better correlation with rotator cuff pathology compared with the axial coraco-humeral distance. MATERIALS AND METHODS A retrospective review was performed of 100 consecutive shoulder MR arthrograms. Vertical distance between the coracoid tip and the supraglenoid tubercle was measured in the sagittal oblique plane. Separate assessment was then made of tendon pathology of the subscapularis, supraspinatus and long head of biceps tendons. Axial coraco-humeral distance was then measured. Correlation between tendon abnormalities and the two measurements was then made. RESULTS Of the 100 cases, 42 had subscapularis tendon lesions, 21 had lesions of the long head of biceps and 53 had supraspinatus tendon lesions. Mean vertical distance from the coracoid tip to supraglenoid tubercle was greater in those with lesions of any of these tendons and was statistically significant for the supraspinatus group (P = 0.005). Reduced axial coraco-humeral distance was also seen in patients with tendinopathy, although with less statistically significant difference (p = 0.059). CONCLUSION Our results support orthopaedic studies that have shown that the vertical distance between the coracoid tip and the supraglenoid tubercle increases the incidence and risk of rotator cuff disease by altering the shape of the subcoracoid outlet.

Abstract
We report on a 36-year-old man who underwent arthroscopic debridement for bilateral calcific tendinitis of the subscapularis tendons. The patient had a positive coracoid impingement test for both shoulders. Radiology showed calcific deposits at the insertion of both subscapularis tendons, close to the lesser tuberosities and just posterior to the coracoid tips. The patient underwent sequential arthroscopic coracoplasty and removal of calcific deposits in the subscapularis tendons. The patient returned to work 6 weeks after each surgery. At 2 years, the patient had no shoulder pain, with full range of motion and full power of the subscapularis muscles. The coracoid impingement test was negative for both shoulders. There was no evidence of recurrence.

Abstract
OBJECTIVE Coracoid impingement is an uncommon cause of the shoulder pain. It is stimulated by adduction, internal rotation and forward flexion. These positions decrease the width of the coracohumeral interval. Owing to restriction of movement, rotator cuff tendons may be overloaded. Thus, in this study, we aimed to determine whether coracoid impingement increase the tendency of rotator cuff tears. MATERIALS AND METHODS Routine clinical MRI sequences of 117 shoulders were reviewed, and axial coracohumeral interval measurements were taken. Rotator cuff tendon integrity was evaluated. Relation between rotator cuff tear and coracohumeral interval width was commented statically. RESULTS Seventy-nine of the patients were women, 38 of them men. The average age was 44.8 ± 14.2 (14-75). The mean age of patients with rotator cuff tear was significantly higher than patients without tear (p = 0.001). The mean value of coracohumeral interval width was 8.853 ± 2.491 mm (min: 2.9-max: 15.8). There were no significant differences between coracohumeral interval width of women and men (p = 0.139). The mean value of coracohumeral interval width with rotator cuff tear was 8.362 ± 2.382, and without tear was 9.351 ± 2.520. There was a significant differences between them (p = 0.031). CONCLUSION According to our study, there was a relationship between coracohumeral interval width and rotator cuff tear, so decreasing coracohumeral interval width may increase tendency of rotator cuff tear.

Abstract
Background: Reduced coracohumeral distances have been reported to be associated with anterior shoulder disorders such as subscapularis tears, biceps tendon injuries, and leading edge supraspinatus tears. Purpose: To determine the variability in coracohumeral distance as a function of arm rotation in healthy male subjects. The null hypothesis was that no differences in coracohumeral distance would exist with respect to arm rotation. Study Design: Descriptive laboratory study. Methods: A total of 9 male participants who had full range of motion, strength, and no prior surgery or symptoms in their tested shoulders were enrolled in this institutional review board–approved study. Computed tomography scans of the shoulder were obtained for each subject. A dynamic biplane fluoroscopy system recorded internal and external shoulder rotation with the arm held in the neutral position. Three-dimensional reconstructions of each motion were generated, and the coracohumeral distance and coracoid index (lateral extension of the coracoid) were measured. Results: The mean coracohumeral distance in neutral rotation was 12.7 ± 2.1 mm. A significantly shorter minimum coracohumeral distance of 10.6 ± 1.8 mm was achieved (P = .001) at a mean glenohumeral joint internal rotation angle of 36.6° ± 19.2°. This corresponded to a reduction in coracohumeral distance of 16.4% (range, 6.6%-29.8%). The mean coracoid index was 14.2 ± 6.8 mm. A moderate correlation (R = −0.75) existed between the coracohumeral distance and coracoid index. Conclusion: Coracohumeral distance was reduced during internal rotation. Decreased coracohumeral distance was correlated with larger coracoid indices. Clinical Relevance: This study provides a reference value for coracohumeral distance in the healthy male population. Knowledge of how coracohumeral distance varies over the range of arm internal-external rotation may improve the clinical diagnosis and treatment plan for patients with anterior shoulder pathology, specifically subcoracoid impingement. Imaging of the coracohumeral distance during internal rotation with the hand at approximately midline should be considered to assess patients with anterior shoulder pain.

Abstract
For many years, coracoid impingement has been a well-recognized cause of anterior shoulder pain. However, a precise diagnosis of coracoid impingement remains difficult in some cases due to the presence of multifactorial pathologies and a paucity of supporting evidence in the literature. This review provides an update on the current anatomical and biomechanical knowledge regarding this pathology, describes the diagnostic process, and discusses the possible treatment options, based on a systematic review of the literature.

Abstract
OBJECTIVE Relate the main tendinous and ligamentous structures attached in the coracoid process, correlating it to several levels of osteotomy and describing the involved structures. METHODS Thirty shoulders were dissected. The coracoid process with mainly inserted anatomic structures was dissected, and five levels of osteotomy (1.0; 1.5; 2.0; 2.5; 3.0 cm) were made from the apex of the process and the mainly involved structures were recorded. RESULTS In osteotomies of 1.0 cm, in 100% of the cases only the conjoint tendon (CT). In osteotomies of 1.5 cm there were 63.33% of cases involved with the CT and the Pectoralis minor (PMi), in 20% of cases only the CT, and in 16.66% the CT, PMi, and the coracohumeral ligament (CUL). In osteotomies of 2.0 cm, in 80% of the shoulders, the osteotomies embraced the CT, PMi and the CUL, and in 20% only the CT and the PMi were involved. In the osteotomies of 2.5cm there was involvement of the CT, PMi and CUL in 100% of cases. In the osteotomies of 3.0cm, six cases (20%) have presented an injury on the trapezoid ligament, and in 100% of these osteotomies, the osteotomized distal fragment had embraced the CT, PMi, CUL. CONCLUSION The knowledge of anatomic structures inserted and involved in the osteotomies cuts of the coracoid process is very importan to lead with osteotomies performed in the treatment techniques of the coracoid process. Osteotomies of 3.0 cm can injure the trapezoid ligament.

Abstract
Coracoid impingement is a controversial, well-known diagnosis that results in anterior shoulder pain. Idiopathic, traumatic, and iatrogenic etiologies have been identified. Proper diagnosis requires a focused clinical examination of the anterior shoulder and adjacent structures. MRI and CT are helpful in evaluating coracoid morphology as well as the integrity of the rotator cuff and long head of the biceps. Imaging is an essential diagnostic tool. Initial management consists of physical therapy and injection therapies. Surgery may be required when nonsurgical methods are unsuccessful. Successful functional and subjective outcomes have been reported with both open and arthroscopic techniques.

Abstract
Shoulder impingement is a common condition presumed to contribute to rotator cuff disease. Impingement can occur externally with the coracoacromial arch or internally with the glenoid rim. Normal scapulothoracic motions that occur during arm elevation include upward rotation, posterior tilting, and either internal or external rotation. These scapulothoracic motions and positions are the result of coupled interactions between sternoclavicular and acromioclavicular joints. The sternoclavicular and acromioclavicular joints both contribute to scapulothoracic upward rotation. Posterior tilting is primarily an acromioclavicular joint motion. The sternoclavicular and acromioclavicular joint motions offset one another regarding final scapulothoracic internal/external rotation position. This manuscript discusses these coupled interactions in relation to shoulder muscle function. Two case examples are presented to demonstrate application of understanding these interactions and potential mechanisms of movement abnormalities in targeting treatment interventions for movement based subgroups of impingement patients.
