Humeral head retroversion is not well described with the literature controversial regarding accuracy of measurement methods and ranges of normal values. Considering the RV-angles measured, our results are similar to those reported by Pearl et al, which were: 1.8° and 5.8° compared to 20.2° and 18.9°, respectively, depending on the method of measurement. The proximal axes were: (1) the perpendicular line to the borders of the articular surface (humeral centerline); and (2) the longest diameter through the humeral head. The ischial spine sign is also a marker of retroversion, which occurs when the ischial spine projects into the pelvis on an AP view (Fig. (Reproduced with modification from: Pearl ML. Additionally, muscle ratio (SSc/IS) on the involved side was significantly smaller compared to the uninvolved side (P = 0.007), but was not related to alterations in humeral version. Differences in humeral head version and glenoid version were assessed between dominant and nondominant shoulders and between men and women. Statistical analysis was performed using SPSS software (version 22.0; SPSS Inc., Chicago, IL, United States). During sedation, they were monitored by electrocardiograph, measurement of oxygen saturation, and by video. J Shoulder Elbow Surg. 2019 Apr;11(2):79-86. doi: 10.1177/1758573217728291. The retroversion of the humerus was measured by determining the orientation of the proximal articular surface of the humerus with respect to the transepicondylar line of the distal part of the humerus and the forearm axis. Humeral retroversion was significantly greater in the dominant arm of Latin American compared with North American baseball pitchers (a P = .034). Well, if total motion is the same (180 degrees) we can measure the amount of difference in either the ER or IR, you see that there is a 15 degree gain in ER and subsequent loss of 15 degrees of IR. This study was IRB approved. Matsumura N, Oki S, Ogawa K, Iwamoto T, Ochi K, Sato K, Nagura T. J Shoulder Elbow Surg. We measured humeral version relative to two proximal axes and one distal axis (transepicondylar axis). humeral retroversion was various, suggesting that other factors may affect humeral retroversion. USA.gov. Walch B0 glenoid: pre-osteoarthritic posterior subluxation of the humeral head. Checklist of Responsibilities for the Scientific Editor of This Article. Methods: Interest in the glenoid hull method for analyzing humeral subluxation in primary glenohumeral osteoarthritis. eCollection 2020. A 3D comparison of humeral head retroversion by sex and measurement technique. The size of the SSc and IS muscles on the involved side was significantly decreased, 2.26 cm² vs 2.79 cm² and 1.53 cm² vs 2.19 cm², respectively (P < 0.05). West EA, Knowles NK, Athwal GS, Ferreira LM. Both the humeral head and glenoid are thought to be more retroverted in high-demand shoulders. In Table 2, the results of the muscle cross-sectional area measurements are summarized. Retroversion was analyzed using the humeral center-line (HCL) as the proximal axis (Figure 1). This site needs JavaScript to work properly. Correlation analyses were also performed in the values of version between dominant and nondominant shoulders and between humeral head version and glenoid version. When treatment becomes warranted and contralateral humeral version measurements greatly differ, a humeral derotational osteotomy may offer the best improvement regarding the hand position. Scapular resting position and gleno-humeral movement dysfunction in asymptomatic racquet players: a case-control study Assessment of the Glenoid Morphology Based on Demographic Data in the Turkish Population. The morphologic features and clinical significance of version of the humeral head and glenoid remain unclear. 2014 Apr 16;96(8):e64. Copyright © 2014 Journal of Shoulder and Elbow Surgery Board of Trustees. Muscle cross-sectional areas of the IS and SSc muscles were measured on the MRI-slides representing the largest muscle belly. However, the mean age of the study groups differed considerably, 3.2 years old vs 4.3 mo old. 2020 Nov 15. doi: 10.1002/ca.23703. The 35 children included in our study had a mean age of 4.3 mo (range of 2.1-6.5 mo), and they were classified according to the Narakas classification: Narakas I: 18 cases; Narakas II: 4 cases; Narakas III: 15 cases. Additionally, cross-sectional areas of the infraspinatus (IS) and subscapularis (SSc) muscles were measured. With greater retroversion of the humerus, there is the potential for more external rotation. 5) is defined by the fossa touching or crossing the ilioischial line. These findings are relevant for any child under consideration for surgical intervention aiming to improve external rotation, since all other factors being equal, decreased humeral retroversion results in an increased severity of the clinical presentation of an internal rotation contracture. Furthermore, the muscle ratio (SSc/IS) on the involved side was significantly smaller compared to the uninvolved side (P = 0.007). Additionally, the role of the infraspinatus (IS) and subscapularis (SSc) muscles in the genesis of this bony deformation is explored. Therefore, we chose to utilize methods often used in our clinic setting and shown in a prior publication[12]. A trend (b P = .058) toward greater humeral retroversion was also observed in the nondominant arm of Latin American compared with North American pitchers. Figure 3 shows the distribution of measurements. Since the subscapularis (SSc) and infraspinatus (IS) muscles, are an agonist-antagonist muscle pair regarding humeral rotation, we hypothesized that an imbalance between these muscles would correlate with altered humeral version. Furthermore, muscle thickness was only assessed for the IS and SSc muscles, and the measurement of other external and internal rotator muscles may offer additional insight into muscle behavior and its effect on humeral retroversion in this population. Further research is necessary to elucidate a causal relationship between those mechanisms and shoulder deformities, concerning both the humerus and glenoid, which will help guide clinical treatment decisions for BPBI. Mean RV-angles were 8.5° vs 25.4° (P < 0.001). Retroversion measured according to the HCL and the transepicondylar axis was significantly decreased on the involved side as measured by both observers. Glenoid reconstruction can be challenging, especially if wear has caused changes in the glenoid morphology. Bouacida S, Gauci MO, Coulet B, Lazerges C, Cyteval C, Boileau P, Chammas M. J Shoulder Elbow Surg. A computer tomography morphometric study. The mean humeral retroversion of the affected shoulder was significantly increased compared with the normal contralateral side (-28.4 +/- 12.5 degrees v -21.5 +/- 15.1 degrees, p = 0.02). The fulcrum axis: an accurate measure of glenoid version on radiographs and computed tomography. This axis is conforming to the longest diameter through the humeral head. Shoulder Elbow. Age was again not correlated with a decrease in humeral retroversion (r = -0.120, P = 0.492). The HCL represents the perpendicular projection from the margins of the articular surface. Figure 2 shows the distribution of the measurements. The most common musculoskeletal sequela of neurologic injury of brachial plexus birth palsy (BPBI) is an internal rotation contracture of the shoulder. Both humeral head retroversion and glenoid retroversion were significantly higher on the dominant side than on the nondominant side and significantly higher in men than in women. The retroversion angle Glenoid version was found to be 1.5° of retroversion in men and 0.9° of retroversion in women. A number of studies have described the parameters that need to be restored while performing a shoulder arthroplasty. Results: We found a significant reduction of humeral retroversion on the involved side compared to the uninvolved side in a consecutive series of patients with internal rotation contractures secondary to BPBI. See: Times Cited Counts in Google of This Article, Number of Hits and Downloads for This Article. A prospective study analyzing possible changes in humeral version in this patient population over time would be of interest, as it seems through these results and results from recent studies that changes in humeral version occur early, but that they may not change much after that. Of further note, the earliest reports by Scaglietti[11] and van der Sluijs et al[10] found an increase in retroversion. MRI studies were performed on a 1.5-T MRI-unit (Magnetom 1.5 T Vision; Siemens, Erlangen, Germany). The existing common treatment options for children suffering from brachial plexus birth palsy all strive for better function of the upper extremity through an improved position of the hand in space. Images for analysis were computed tomography scans of 410 normal shoulders from healthy volunteers. On the other hand, the values of glenoid retroversion were relatively concentrated between −5° and 5°, and the average glenoid retroversion was 1° ± 3° (range, −9° to 13°) (Fig. Passive external rotation was measured with the arm in the adducted position and the elbow by the side. Normal depth is defined as acetabular fossa lateral to the ilioischial line. Twenty-two patients had traumatic anterior shoulder dislocations and another 12 patients had … Conclusions: - if posterior glenoid bone loss is present, consider altering amount of humeral retroversion from the normal 35 deg to a less retroverted position; - attempt to recreate the normal humeral … As such, the aim of this imaging-based anthropometric study was to investigate humeral torsion in Walch type B shoulders. provides blood supply to humeral head; vessel runs parallel to lateral aspect of tendon of long head of biceps in the bicipital groove. The average humeral head retroversion was 26° ± 11°. We found a significant reduction of humeral retroversion in our study group (mean difference, 26.8).

For retroversion measured using the SA, the ICC for interrater reliability on the involved side was 0.934 (95%CI: 0.897-0.970; P < 0.001).  |  Capturing the full volume of both muscles would likely have been more informative; however, such software tools were not available to us. © 2004-2021 Baishideng Publishing Group Inc. All rights reserved. Normal humeral retroversion is greatest at birth and gradually decreases through adolescence [13-15] to adult values averaging between 25-30 with well documented individual variation . A FISP three-dimensional pulse acquisition sequence (repetition time, 25 msec; time to echo, 10 msec; flip angle 40°) with ranges from 0.8 to 1.5 mm partitions was used to obtain images from both shoulders and upper arms, representing the full humerus and glenohumeral joint in the axial plane. Humeral head. Bilateral magnetic resonance imaging (MRI) scans of 35 infants (age range: 2-7 mo old) with BPBI were retrospectively analyzed. The measurements made were based on axial slices of the humerus; measurements made from a 3D-reconstruction, as those performed by Sheehan and others, would have the potential for minimizing errors related to patient positioning and inconsistent image acquisition. This contracture is frequently associated with deformity of the glenohumeral joint[1-5]. 12). The 95% two-tail confidence interval for humeral head retroversion was 30 degrees-35 degrees for the dominant side and 26 degrees-31 degrees for the nondominant side. Humeral retroversion and shoulder muscle changes in infants with internal rotation contractures following brachial plexus birth palsy. Results: The values of humeral head retroversion were widely distributed from -2° to 60°, with an average of 26°±11°. Average glenoid retroversion was 1° ± 3°, ranging from -9° to 13°. Nonetheless, the reduction in muscle ratio does not support the theory that the internal rotators overpower the injured (paralyzed) external rotators, but suggests that failure of the SSc to grow or develop may result in a contracted SSc, which restricts external rotation. Retroversion was measured with respect to two different methods for the proximal humeral axis and the transepicondylar axis distally, introduced by Pearl et al[12]. However, the SA yielded systematically higher values in the deformed humeral head compared to the HCL. Epub 2017 Aug 30. van de Bunt F, Pearl ML, van Essen T, van der Sluijs JA. Humeral retroversion isn’t necessarily a bad thing. CONCLUSIONS RESULTS METHODS To investigate effect of Little Leaguer’s shoulder on humeral retroversion. Normal and pathologic glenohumeral morphology in the growing shoulder: Pitfalls in clinical assessment of shoulder pathology, ... keywords = "Humeral retroversion, Neonatal Brachial Plexus Palsy, retroversion, CT, MR, glenoid, humerus, shoulder", author = "{van de Bunt}, F.", Normal humeral retroversion is greatest at birth and gradually decreases through adolescence[13-15] to adult values averaging between 25-30 with well documented individual variation[16]. Cross-sectional areas of the IS and SSc muscles were measured using the closed region-of-interest polygon tool in Osirix (Pixmeo). This position is directly related to the humeral version angle. Results depend on proper implant selection, posit… 2016 Mar;25(3):493-501. doi: 10.1016/j.jse.2015.08.003. From these 37 studies, two were insufficient for completing our detailed measurement protocol, as one study did not capture the entire humerus and motion artifacts compromised the other study. Furthermore, the muscle ratio (SSc/IS) at the involved side was significantly smaller compared to the uninvolved side (P = 0.007). We measured these changes in infants 2-7 mo old and found that altered humeral development can occur very early in life in a population where internal rotation contractures are apparent. Paired differences averaged 26.8°, with a range from -18.4° to 77.8°. Based on the literature, retroversion of the humeral head is shown as a positive value and anteversion is shown as a negative value. The glenoid and humeral head in shoulder osteoarthritis: A comprehensive review. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. Further study of other muscles is warranted, looking for evidence as to whether they were also injured resulting in impaired growth[7,37], or whether they recovered so strongly that they overwhelmed their antagonists or are used differently in children with varying levels of recovery. The ICC for interrater reliability on the uninvolved side was 0.889 (95%CI: 0.747-0.948; P < 0.001). ascending branch of anterior humeral circumflex artery and arcuate artery . In this retrospective observational study, we included 37 Magnetic resonance imaging (MRI) -scans from a consecutive series of infants (< 1 year old) with a unilateral BPBI. We measured retroversion in 65 cadaveric humeri, including 52 paired specimens, using four methods: radiographic, computed tomography (CT) … The purpose of this study was to evaluate the normal values of humeral head version and glenoid version on computed tomography scans and to clarify their features in the normal glenohumeral joint. Published by Baishideng Publishing Group Inc. All rights reserved. Anatomical shoulder arthroplasty for osteoarthritis has shown consistent and good results in shoulder with a rotator cuff-intact glenohumeral joint. In combination with other internal rotator muscles such as the pectoralis muscle, mechanical stiffness of these muscle fibers may not be directly related to cross-sectional muscle area measurements. Average glenoid retroversion was 1° ± 3°, ranging from -9° to 13°. beware not to injure when plating proximal humerus fractures • Little Leaguer’s shoulder, which is rotational stress fracture of the proximal humeral epiphyseal plate, may change humeral retroversion. Our results show that altered humeral development can occur very early in life in a population where internal rotation contractures are apparent. Our objective was to elucidate the timing that decreased retroversion may occur; therefore, we included our youngest patient population (2-7 mo old). 2017 Jul;26(7):1128-1136. doi: 10.1016/j.jse.2017.01.027. A prospective study analyzing changes in humeral version over time would be of interest to assess the predictive value of decreased retroversion at such a young age, concerning various treatment options (soft-tissue and bony). For example, impaired growth and increased stiffness of the SSc muscle fibers may have a significant effect on humeral version development. A large reduction in humeral retroversion at a very young age could be a predictor (or an argument when apparent at an older age), for the necessity of a humeral derotational osteotomy, to provide adequate improvement of hand and possibly elbow function. Both measurement methods yielded comparable results in the uninvolved shoulder. A line segment was created, which spanned the greatest distance from the periphery of the greater tuberosity to the medial articular surface and is labeled as the skew axis (SA) (Figure 1)[2]. Internal rotation contractures varied from -45° to 12°, with a mean of -18°, measured as passive external rotation with the elbow by the side (Table 1). For humeral version measurements, axial plane slides from the involved and uninvolved side that to our best efforts represented the midpoint of the humeral head were selected. They studied this relationship as correlations between lines at the humeral and at … These surgical interventions all aim for better function through an improved position of the hand in space. To evaluate this method of measuring retroversion, the protocol was tested in patients before and after shoulder arthroplasty. The existing common treatment options all strive for better function of the upper extremity through an improved position of the hand in space.

The mean difference in retroversion correlated significantly by Pearson's product moment with the difference in external (P = 0.001) and internal (P = 0.003) rotation measurements. Furthermore, this study shows that secondary osseous changes can occur within several months in this patient population. In addition, animal studies have shown that impaired longitudinal muscle growth and strength imbalance mechanisms are capable of producing shoulder deformities and impaired growth to a somewhat greater extent than muscle imbalance[8,38-41]. Both muscles were significantly smaller on the involved side. Keywords: Retroversion on the involved side was significantly decreased, 1.0° vs 27.6° (1) and 8.5° vs 27.2° (2), (P < 0.01), as compared to the uninvolved side. Our results suggest that declined humeral version is not something these children slowly grow into. Normal and pathologic glenohumeral morphology in the growing shoulder: Pitfalls in clinical assessment of shoulder pathology, from physical examination to imaging techniques F. van de Bunt Research output : PhD Thesis › PhD Thesis - Research VU, graduation VU CT scan methods accurately measure humeral head retroversion, while radiographic methods do not. Retroversion measured according to the SA and the transepicondylar axis was also significantly decreased on the involved side, as measured by both observers. However, this has not yet been related to altered humeral version. However, no significant correlation between the muscle ratio (SSc/IS) and the humeral RV-angle was observed. Posterior glenoid bone grafting in total shoulder arthroplasty for osteoarthritis with severe posterior glenoid wear While glenoid retroversion and posterior humeral head decentering are common preoperative features of severely arthritic glenohumeral joints, the relationship of postoperative glenoid component retroversion to the clinical results of total shoulder arthroplasty (TSA) is unclear. Humeral retroversion measured 36.6° ± 9.8° in the dominant and 26° ± 9.4° in the nondominant extremity. HHS The values of humeral head retroversion were widely distributed from -2° to 60°, with an average of 26° ± 11°. Since earlier studies did not reveal a correlation between age and decreased retroversion on the involved side, the question remained at what age this anatomic change may occur. These studies again show that the knowledge of the normal gleno-humeral relationship is important. The distribution of measurements was larger on the involved side (Figure 4). Is global humeral head offset related to intramedullary canal width? So the humerus must be retroverted 15 degrees. eCollection 2018 Dec 18.  |  2020 Feb 10;2020:5736136. doi: 10.1155/2020/5736136. COVID-19 is an emerging, rapidly evolving situation. The proximal axes were: (1) the perpendicular line to the borders of the articular surface (humeral centerline), and (2) the longest diameter through the humeral head. retroversion angle, based on the axial rotation of the humeral head in an axial transverse plane, is measured as the angle between the axes of the humeral diaphysis and the humeral … 2018 Dec 18;9(12):292-299. doi: 10.5312/wjo.v9.i12.292. Children were not moved during the imaging protocol. In our studied age group, the humeral head and epicondylar axis are mostly cartilaginous, making 3D-reconstruction of the humeral anatomy much more challenging than in a skeletally mature subject. Please enable it to take advantage of the complete set of features! Results: The values of humeral head retroversion were widely distributed from -2° to 60°, with an average of 26° ± 11°. The average angle for humeral head retroversion was 33 degrees on the dominant side and 29 degrees for the nondominant side. All children were given pethidine, droperidol and chlorpromazine intramuscularly. Two investigators performed the humeral version measurements. To examine humeral retroversion in infants who sustained brachial plexus birth palsy (BPBI) and suffered from an internal rotation contracture. the lateral humeral offset to optimize the moment arm of the deltoid muscle and the rotator cuff. Core tip: This study examines humeral retroversion in infants who sustained neonatal brachial plexus palsy and suffered from an internal rotation contracture. This study found differences in humeral head version and glenoid version by sex and shoulder dominance in a large sample. van der Sluijs et al[10] utilized MRI, but nearly two decades ago in a somewhat older age group, when current software tools were not available for image analysis, and the lesser image quality might have influenced measurements. Methods: Three-dimensional models of the full-length humerus were generated from computed tomography data for the Walch type B group (n = 59)and for a control group of normal nonarthritic shoulders (n = 59). Humeral head retroversion is not well described with the literature controversial regarding accuracy of measurement methods and ranges of normal values. Paired differences averaged 17.5°, with a range from -22.2° to 53.3°. Pearson product-moment or Spearman rank correlation coefficients are estimated between each of these and passive external rotation and Narakas classification, as appropriate, based on the underlying distribution and type of the data. The difference in retroversion was correlated with the ratio of muscle sizes. 3D CT assessment of the relationship between humeral head alignment and glenoid retroversion in glenohumeral osteoarthritis. In the deformed humeral head, the skew axis yields systematically higher values compared to the humeral center line. Furthermore, the ratio of the SSc and IS muscle (SSc/IS) was calculated to compare muscle balance between both sides and correlate these with the ΔRV-angle. Would you like email updates of new search results? The internal rotation contracture secondary to BPBI has been associated with alterations of humeral retroversion[9-12]. Another explanation for the increased external rotation can be possibly attributed to increased humeral retroversion which is a common finding in players playing overhead sports (31-33). The distribution analysis showed an approximately normal distribution. This position is directly related to the humeral version angle. Retroversion was measured according to two proximal axes and one distal axis (transepicondylar axis). One well-studied exception is the throwing athlete, for whom retroversion has been shown to be greater on the dominant throwing side, due to repetitive throwing that usually begins in early childhood[17-21]. One well-studied exception is the throwing athlete, for whom retroversion has been shown to be greater on the dominant throwing side, due to repetitive throwing that usually begins in early childhood [ 17 - 21 ] . Background: It’s actually what allows pitchers to pitch really. Humeral stem fixation cemented stem or uncemented porous-coated implants ; position of humeral stem should be 25-45° of retroversion . Even in our youngest patient population, humeral retroversion has a high likelihood of being decreased. Therefore, a thorough understanding of the development of the pathogenesis of this injury is important. The center of rotation of the normal humeral head is, on NIH Muscle size was determined by the muscle cross-sectional area in cm2 and muscle percentage relative to the corresponding muscle at the uninvolved side. This study was conducted to compare the concordance and reliability between the standard method and 5 other measurement methods on two-dimensional (2D) computed tomography (CT) scans.CT scans from 21 patients who underwent shoulder arthroplasty (19 women and 2 men; mean … Epub 2017 Sep 28. We hypothesized that the retroversion angle (RV-angle) on the involved side would be significantly decreased relative to the uninvolved side and that the difference would increase with age. Both humeral head retroversion and glenoid retroversion were significantly higher on the dominant side than on the nondominant side and significantly higher in men than in women. Sarı A, Dinçel YM, Günaydın B, Çetin MÜ, Özçaglayan Ö, Bilsel K. Biomed Res Int. We measured retroversion in 65 cadaveric humeri, including 52 paired specimens, using four methods: radiographic, computed … World J Orthop. Age did not correlate with a decrease in humeral retroversion (r = -0.108, P = 0.538). Scaglietti’s study was in a very different era of imaging technology and presented his observations with little quantitative data.
