Abstract
Neurogenic pain and inflammation have been hypothesised to play an important role in tendinopathy. This systematic review aimed to present and assess the evidence on neurogenic inflammation in tendinopathy. A systematic search was conducted through multiple databases to identify human case-control studies assessing neurogenic inflammation through the upregulation of relevant cells, receptors, markers and mediators. A newly devised tool was used for the methodological quality assessment of studies. Results were pooled based on the cell/receptor/marker/mediator assessed. A total of 31 case-control studies were eligible for inclusion. The tendinopathic tissue was obtained from Achilles (n=11), patellar (n=8), extensor carpi radialis brevis (n=4), rotator cuff (n=4), distal biceps (n=3) and gluteal (n=1) tendons. Through pooling the results of included studies based on the marker of neurogenic inflammation assessed, we identified possible upregulation of protein gene product 9.5 (PGP 9.5), N-methyl-D-aspartate Receptors, glutamate, glutamate receptors (mGLUT), neuropeptide Y (NPY) and adrenoreceptors in tendinopathic tissue versus control. Calcitonin gene-related peptide (CGRP) was not found to be upregulated, and the evidence was conflicting for several other markers. These findings show the involvement of the glutaminergic and sympathetic nervous systems and the upregulation of nerve ingrowth markers supporting the concept that neurogenic inflammation plays a role in tendinopathy.

[PMID: 35578947 DOI: 10.1111/joa.13685] [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: 09/03/2021] [Revised: 04/19/2022] [Accepted: 04/26/2022] [Indexed: 01/14/2023] Open
Abstract
The proximal long head of the biceps tendon (LHBT) has been recognized as a well-known cause of anterior shoulder pain. Previous studies have identified a heterogeneous distribution of nerve fibers in the tendon, with a higher abundance of fibers in the proximal and distal thirds of the tendon. This suggests that the proximal portion of the long head biceps tendon may have a different source of innervation than the distal portion. The purpose of this study was to review the innervation of the superior shoulder and identify the proximal source of sensory innervation of the LHBT. The relevant hypothesis was that the suprascapular nerve (SSN) was the proximal source of sensory innervation to the LHBT. Gross and microdissection of eight fresh human cadaver shoulders were performed, with a focus on the distal articular branches of suprascapular nerve (SSN). Utilizing 3.5× magnification loupes, the medial subacromial branch (MSAb), lateral subacromial branch (LSAb), and posterior glenohumeral branch (PGHb) were identified and followed distally to their terminal branches. In all specimens, terminal branches of the lateral subacromial branch supplied the proximal LHBT and the superior labrum. Terminal branches of the posterior glenohumeral branch supplied the posterosuperior labrum and, to a lesser extent, the labral attachment of the LHBT. These findings confirm branches of the suprascapular nerve as the proximal source of sensory innervation to the LHBT. Identification of the suprascapular nerve as a source of proximal innervation of the LHBT may influence clinical decisions related to nonsurgical and surgical intervention, nerve blocks, and nerve ablation procedures.

Abstract
ABSTRACT The primary organ systems and tissues concerning plastic and reconstructive surgery include the integument, vasculature, subcutis, and peripheral nerves, because these may individually or collectively be injured requiring reconstruction, or indeed be used in reconstruction themselves through grafts, flaps, or anastomoses. Adrenergic receptors are present throughout these anatomic components on the vasculature, adipose, platelets, immune cells, keratinocytes, melanocytes, fibroblasts, peripheral nerves, and tendons. Herein, the influence of adrenergic signaling on the physiology of anatomic components related to plastic surgery is discussed, along with clinical considerations of this systems involvement in procedures, such as free flap reconstruction, skin grafting, fat grafting, and other areas relevant to plastic and reconstructive surgery. Current evidence as well as potential for further investigation is discussed.

Abstract
Adrenoceptors (ARs) mediate the effects of the sympathetic neurotransmitters norepinephrine (NE) and epinephrine (E) in the human body and play a central role in physiologic and pathologic processes. Therefore, ARs have long been recognized as targets for therapeutic agents, especially in the field of cardiovascular medicine. During the past decades, the contribution of the sympathetic nervous system (SNS) and particularly of its major peripheral catecholamine NE to the pathogenesis of osteoarthritis (OA) attracted growing interest. OA is the most common degenerative joint disorder worldwide and a disease of the whole joint. It is characterized by progressive degradation of articular cartilage, synovial inflammation, osteophyte formation, and subchondral bone sclerosis mostly resulting in chronic pain. The subchondral bone marrow, the periosteum, the synovium, the vascular meniscus and numerous tendons and ligaments are innervated by tyrosine hydroxylase-positive (TH+) sympathetic nerve fibers that release NE into the synovial fluid and cells of all abovementioned joint tissues express at least one out of nine AR subtypes. During the past decades, several in vitro studies explored the AR-mediated effects of NE on different cell types in the joint. So far, only a few studies used animal OA models to investigate the contribution of distinct AR subtypes to OA pathogenesis in vivo. This narrative review shortly summarizes the current background knowledge about ARs and their signalling pathways at first. In the second part, we focus on recent findings in the field of NE-induced AR-mediated signalling in different joint tissues during OA pathogenesis and at the end, we will delineate the potential of targeting the adrenergic signalling for OA prevention or treatment. We used the PubMed bibliographic database to search for keywords such as 'joint' or 'cartilage' or 'synovium' or 'bone' and 'osteoarthritis' and/or 'trauma' and 'sympathetic nerve fibers' and/or 'norepinephrine' and 'adrenergic receptors / adrenoceptors' as well as 'adrenergic therapy'.

Abstract
INTRODUCTION Long head of biceps (LHB) pathologies are an important cause of pain and dysfunction. As LHB pathologies have specific components from other underlying or related pathologies, the LHB score is designed for an accurate assessment. The aim of this study was to adapt the LHB score into Turkish and to assess its validity and reliability. MATERIALS AND METHODS LHB score was translated and culturally adapted from English to Turkish, and then it was applied to 62 patients with biceps long head pathology. The reliability of the scale was checked through internal consistency and test-retest methods. Internal consistency was computed with Cronbach alpha value. Test-retest reliability was assessed using an intraclass correlation coefficient. American Shoulder and Elbow Surgeons Standard Shoulder Assessment Form and modified Constant-Murley score were used to analyze concurrent validity. RESULTS The Cronbach alpha value of the scale was found as .640. When the subsections of LHB score were computed separately, Cronbach alpha levels of pain/cramps and cosmesis sections were found as .753 and .774, respectively. The intraclass correlation coefficient value of the scale was found to be excellent (.940; P < .001). The total LHB score was determined to have a good positive correlation with the American Shoulder and Elbow Surgeons Standard Shoulder Assessment Form (.527) and Constant-Murley score (.516). But an excellent correlation was revealed between the pain/cramps section of LHB score and other pain sections in American Shoulder and Elbow Surgeons Standard Shoulder Assessment Form (.811) and Constant-Murley score (.816) (P < .001). There was an excellent correlation (.916) between cosmesis section and Popeye sign (P < .001). There was a moderate correlation (.469) between elbow-flexion strength section of LHB score and the digital handheld dynamometer outcomes (P < .001). CONCLUSION The Turkish version of the LHB is a valid and reliable tool, especially for biceps pathologies.

Abstract
The innervation of the long head of the biceps tendon (LHBT) is not sufficiently documented. This is a drawback since pathologies of the LHBT are a major source of shoulder pain. Thus, the study aimed to characterize structurally and molecularly nervous elements of the LHBT. The proximal part of 11 LHBTs was harvested intraoperatively. There were 8 female and 3 male specimens. Age ranged from 66 to 86 years. For structural analyses, nervous elements were viewed in the transmission electron microscope. For molecular characterization, we used general neuronal markers including antibodies against neurofilament and protein gene product 9.5 (PGP9.5) as well as specific neuronal markers including antibodies against myelin basic protein (MBP), calcitonin gene-related product (CGRP), substance P (SP), tyrosine hydroxylase (TH), and growth-associated protein 43 (GAP43). Anti-neurofilament and anti-PGP9.5 visualized the overall innervation. Anti-MBP visualized myelination, anti-CGRP and anti-SP nociceptive fibers, anti-TH sympathetic nerve fibers, and anti-GAP43 nerve fibers during development and regeneration. Immunolabeled sections were analyzed in the confocal laser scanning microscope. We show that the LHBT contains unmyelinated as well as myelinated nerve fibers which group in nerve fascicles and follow blood vessels. Manny myelinated and unmyelinated axons exhibit molecular features of nociceptive nerve fibers. Another subpopulation of unmyelinated axons exhibits molecular characteristics of sympathetic nerve fibers. Unmyelinated sympathetic fibers and unmyelinated nociceptive fibers express proteins that are found during development and regeneration. Present findings support the hypothesis that ingrowth of nociceptive fibers are the source of chronic tendon pain.

Molecular Pattern and Density of Axons in the Long Head of the Biceps Tendon and the Superior Labrum. J Clin Med 2019; 8:jcm8122129.

Abstract
The type II superior labrum anterior to posterior (SLAP) repair is a viable option in young and demanding patients, although a prolonged period of pain after surgery is described in the literature. The reason for this fact remains unknown. Thus, the purpose of this study was to investigate the molecular pattern of the biceps tendon anchor, where the sutures for repair are placed. The long head of the biceps tendon (LHBT), including the superior labrum, was dissected in the setting of reverse total shoulder arthroplasty. Immunohistochemical staining was performed using neurofilament (NF) and protein gene product (PGP) 9.5 as general markers for axons and calcitonin gene-related peptide (CGRP) and substance P for nociceptive transmission. A quantitative assessment was performed according to the two regions of interest (ROIs), i.e., the anterosuperior (ROI I) and the posterosuperior labrum (ROI II). Eleven LHBTs with a mean age of 73 years (range: 66–87 years) were harvested intraoperatively. Six LHBTs were gained in osteoarthrosis and five in fractures. We found an inhomogeneous distribution of axons in the anterosuperior and posterosuperior parts of the labrum in all the specimens irrespective of the age, gender, and baseline situation. There was a significantly higher number (p < 0.01) as well as density (p < 0.001) of NF-positive axons in ROI I compared to ROI II. Nociceptive fibers were always found along the NF-positive axons. Thus, our results indicate that the biceps tendon anchor itself is a highly innervated region comprising different nerve qualities. The anterosuperior labrum contains a higher absolute number and density of axons compared to the posterosuperior parts. Furthermore, we were able to prove the presence of nociceptive fibers in the superior labrum. The results obtained in this study could contribute to the variability of pain after SLAP repair.

Abstract
Background This study proposed to investigate whether high-sensitivity C-reactive protein (hs-CRP) is an independent risk factor for long head of biceps tendon (LHBT) tear and whether hs-CRP can increase accuracy in diagnosing LHBT tear. Methods This study involved 582 shoulders of 557 consecutive patients who received arthroscopic examinations at the authors’ institution between January 2010 and July 2018. The strengths of associations between LHBT tear and various factors were determined by calculating the odds ratios (ORs), with 95% confidence intervals (CIs), using logistic regression analyses. The studied variables were demographic, physical, social, metabolic, comorbidity, hs-CRP, and pain on a visual analog scale (VAS) factors, as well as those related to rotator cuff tear (RCT). Significant factors in the multivariable logistic analysis were evaluated to determine their diagnostic values, including their likelihood ratios and post-test probabilities for LHBT tear. Results In the multivariable analysis, five variables were significant: age, retraction degree of Patte, subscapularis tendon tear, hs-CRP > 1 mg/L, and pain VAS (p ≤ 0.01). The best combination of determinations for diagnosing LHBT tear, which yielded a strong positive likelihood ratio of 19.07 and a high post-test probability of 96%, was age ≥ 67 years, subscapularis tendon tear, grade of Patte ≥2, hs-CRP > 1, and pain VAS ≥ 7. Conclusions Serum hs-CRP > 1 mg/L is an independent risk factor for LHBT tear, along with the expected risk factors of age, subscapularis tendon tear, retraction degree of Patte, and pain VAS. Serum hs-CRP > 1 mg/L increases the diagnostic accuracy for LHBT tear. Level of evidence Level IV, Clinical case series.

Abstract
PURPOSE Minor or anterosuperior shoulder instability (MSI) is a relatively new concept with other characteristics than recurrent anteroinferior instability (TUBS). MSI includes patients without history of dislocation, with non-specific clinical symptoms and signs but with indications of laxity of (SGHL)/MGHL with isolated injury of (SGHL)/MGHL seen during arthroscopy. TUBS patients typically present with recurrent anteroinferior instability with at least labral injury of the anterior band of the IGHL. In this study, we focus on the postoperative (rehabilitation) course. Our hypothesis is that its duration is prolonged in patients with MSI when compared to those with TUBS. METHODS Thirty-five patients with isolated anterosuperior capsuloligamentous lesions identified during arthroscopic surgery (group I-MSI) and 65 with at least an anteroinferior capsuloligamentous lesion (group II-TUBS) completed a survey that included a questionnaire enquiring into relief of pain and return to activity, the Oxford Shoulder Instability Score (OSIS) and the Western Ontario Shoulder Instability index (WOSI). Final follow-up occurred at a mean of 76 months postoperatively. RESULTS Pain at night, at rest and during overhead activities disappeared later in group I than in group II (respectively, p = 0.03; 0.01; 0.01). Patients with MSI returned later to professional activities (p = 0.02) and to the same sport (p = 0.01). In addition, they had worse outcome as measured by OSIS (p = 0.01) and WOSI (p = 0.07). CONCLUSION Patients with MSI have poorer prospects regarding time to relief of pain, return to work and sports and outcome scores compared to patients with TUBS.

Abstract
BACKGROUND The postoperative course after arthroscopic superior labrum anterior to posterior (SLAP) repair using suture anchors is accompanied by a prolonged period of pain, which might be caused by constriction of nerve fibres. The purpose was to histologically investigate the distribution of neurofilament in the superior labrum and the long head of the biceps tendon (LHBT), i.e. the location of type II SLAP lesions. METHODS Ten LHBTs including the superior labrum were dissected from fresh human specimen and immunohistochemically stained against neurofilament (NF). All slides were scanned at high resolution and converted into tagged image file format, and regions of interest (ROIs) were defined as follows: ROI I-superior labrum anterior to the LHBT origin, ROI II-mid-portion of the superior labrum at the origin of the LHBT, ROI III-superior labrum posterior to the LHBT origin and ROI IV-the most proximal part of the LHBT before its attachment to the superior labrum. The entire images were automatically segmented according to the defined ROIs and measured using a programmed algorithm specifically created for this purpose. The NF-positive cells were counted, and their total size and the area of other tissue were measured separately for the different ROIs. RESULTS Distribution of NF-positive cells in absolute numbers revealed a clear but insignificantly higher amount in favour of ROI I, representing the superior labrum anterior to the LHBT origin. Setting ROI I at 100%, a significant difference could be seen compared to ROI III, representing the superior labrum posterior to the LHBT origin (ROI I vs. ROI III with a p value < 0.05). CONCLUSIONS Summarizing, the density of neurofilament is inhomogeneously distributed throughout the superior labrum with the highest number of neurofilament in the anterior superior labrum. Thus, suture placement in type II SLAP repair could play an important role for the postoperative pain-related outcome.

Abstract
BACKGROUND Tendinopathy is a clinical diagnosis of localised tendon pain often confirmed by imaging findings. The pathophysiological cause of the pain is unknown and the sympathetic nervous system (SNS) may be implicated. OBJECTIVE To review what is known regarding the role of the SNS in human tendinopathy. STUDY SELECTION Published data describing sympathetic innervation or an index of sympathetic activity in human tendons were eligible for inclusion. DATA SOURCES Bibliographical databases (AMED, Biological Abstracts, CINAHL Plus, EMBASE, MEDLINE, Scopus, SPORTDiscus and Web of Science) were searched for relevant articles. Reference lists from included articles were screened for additional articles. STUDY APPRAISAL Studies were scored with a quality assessment tool to identify potential sources of bias. Each question had an explicit decision rule to guide assessment. RESULTS Nine case-control and four cross-sectional studies examined sympathetic innervation of tendons. There was evidence suggesting a lack of difference in sympathetic innervation of tendon proper between tendinopathy biopsies and healthy controls. In contrast, the paratendinous tissue showed evidence of increased sympathetic innervation in painful tendons. The most notable increase in SNS markers was seen in abnormal tenocytes from painful tendons. Data from two studies were suitable for meta-analysis. These heterogeneous studies revealed no difference in sympathetic innervation between painful and pain-free tendons. No studies recorded SNS activity in vivo. CONCLUSION Sympathetic innervation in painful tendons depends on tissue type. Abnormal tenocytes may have increased capacity for self-production of sympathetic neurotransmitters. Future insight may be gained by measuring global in vivo sympathetic drive in tendinopathy.

Abstract
PURPOSE Patients with a shoulder disorder often complain of pain on the anterior or lateral aspect of the shoulder. Such pain has been thought to originate from the suprascapular nerve. However, taking into consideration the distinctive course of the axillary nerve, the axillary nerve is likely to supply branches to the structure around the shoulder joint. This study was conducted to clarify the division, course, and distribution of the branches which originate from the axillary nerve and innervate structures around the shoulder joint. METHODS The division, course, and distribution of the branches which originate from the axillary nerve and innervate structures around the shoulder joint were examined macroscopically by dissecting 20 shoulders of 10 adult Japanese cadavers. RESULTS The thin branches from the anterior branch of the axillary nerve were distributed to the subacromial bursa and the area around the long head of the biceps tendon. The branches from the main trunk of the axillary nerve or the branch to the teres minor muscle were distributed to the infero-posterior part of the shoulder joint. CONCLUSION The pain on the anterior or lateral aspect of the shoulder, which has been thought to originate from the suprascapular nerve, might be related to the thin branches which originate from the axillary nerve and innervate the subacromial bursa and the area around the long head of the biceps tendon. CLINICAL RELEVANCE These results would be useful to consider the cause of the shoulder pain or to prevent the residual pain after the biceps tenodesis.

Abstract
Tears of the rotator cuff are common and becoming an increasingly frequent problem. There is a vast amount of literature on the merits and limitations of the various methods of clinical and radiological assessment of rotator cuff tears. This is also the case with regard to treatment strategies. Certain popular beliefs and principles practiced widely and the basis upon which they are derived may be prone to inaccuracy. We provide an overview of the historical management of rotator cuff tears, as well as an explanation for how and why rotator cuff tears should be managed, and propose a structured methodology for their assessment and treatment.

Arthroscopy 2015; 31:29-34. [PMID: 25239173 DOI: 10.1016/j.arthro.2014.07.025] [Citation(s) in RCA: 67] [Impact Index Per Article: 7.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/13/2014] [Revised: 07/22/2014] [Accepted: 07/25/2014] [Indexed: 02/02/2023]
Abstract
PURPOSE The purpose of this study was to compare arthroscopic versus open examination of the proximal long head of the biceps tendon (LHB) in patients undergoing open, subpectoral tenodesis. METHODS Eighty consecutive patients were prospectively enrolled, of whom 62 were included in the study. During arthroscopy, the most distal extent of the LHB visualized was marked with a Bovie device. The tendon was pulled into the joint with an arthroscopic grasper, showing additional LHB and was again marked with the device. LHB fraying, flattening, redness, and degeneration were graded as absent, mild, moderate, or severe. During open subpectoral tenodesis, the grossly visualized LHB was graded in the same manner and the locations of both marks plus the total length of the LHB observed during open visualization were measured and recorded. After subpectoral tenodesis, the excised portion of the LHB was histologically graded as normal, fibrosis/tendinosis, or inflamed. RESULTS On average, during open tenodesis, 95 mm (range, 75 to 130 mm) of LHB was visualized. This was greater than the length visualized during diagnostic arthroscopy of 16 mm (range, 5 to 28 mm), or 17%, and the length visualized while pulling the tendon into the joint with an arthroscopic grasper of 30 mm (range, 15 to 45 mm), or 32%. The difference in LHB length observed during open versus arthroscopic examination with a grasper was statistically significant (P < .0001). In addition, when compared with LHB pathology observed in an open manner, arthroscopic visualization showed only 67% of pathology, underestimated noted pathology in 56% of patients, and overestimated noted pathology in 11% of patients. Histologic evaluation showed fibrosis/tendinosis in 100% of cases but inflammation in only 5%. CONCLUSIONS When compared with open inspection during subpectoral tenodesis, arthroscopic examination of the LHB visualizes only 32% of the tendon and may underestimate pathology. LEVEL OF EVIDENCE Level II, diagnostic study-development of diagnostic criteria based on consecutive patients with universally applied gold standard.
