Abstract
Musculoskeletal conditions are common in patients with diabetes. Several musculoskeletal disorders are viewed as chronic complications of diabetes because epidemiological studies have revealed high correlations between such complications and diabetes, but the pathophysiological links with diabetes remains unclear. Genetic predispositions, shared risk factors, microvascular impairments, progressive accumulation of advanced glycation end-products, and diabetic neuropathy may underlie the development of musculoskeletal disorders. Musculoskeletal complications of diabetics have received less attention than life-threatening microvascular or macrovascular complications. Here, we review several diabetic musculoskeletal complications with a focus on the clinical importance of early recognition and management, which would improve quality of life and physical function.

Causes of Shoulder Dysfunction in Diabetic Patients: A Review of Literature. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19106228. [PMID: 35627764 PMCID: PMC9140829 DOI: 10.3390/ijerph19106228] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/08/2022] [Revised: 05/13/2022] [Accepted: 05/17/2022] [Indexed: 12/15/2022]
Abstract
Objective: Understanding the underlying mechanisms behind shoulder dysfunctions in patients with diabetes mellitus. Study Design: Systematic qualitative literature review. Participants: Patients with shoulder dysfunctions and diagnosed with impaired glucose tolerance or diabetes mellitus. Intervention: Published scientific literature containing evidence about the mechanisms of shoulder dysfunctions in the diabetic population. Articles were selected based on criteria containing diabetic population, shoulder dysfunction, methodological quality ≥ 6/9 and >20 subjects. Main Outcome measures: range of motion; questionnaires (QoL, UCLA-m, SPADI, DASH); blood glucose, blood HbA1C; calculated capsular stiffness (Kcap); calcification shoulder joint; shoulder dysfunction in patients with glucose metabolism disorders and diabetes mellitus. Results: We found 17 published articles with level 2 and 3 evidence. Multiple factors such as age, duration of diabetes mellitus (DM), glycated hemoglobin (HbA1c), advanced glycation end products (AGE), vascular endothelial growth factor (VEGF), interleukin-1ß (IL-1ß) were shown to be associated with tendon changes and increased capsular stiffness (Kcap) conceivably leading to limited range of motion (ROM) or frozen shoulder. Decreased ROM and frozen shoulder have a significantly higher prevalence in DM than in non-DM. Conclusions: Based on the current literature we confirm a high prevalence of shoulder dysfunctions in patients with diabetes mellitus. The cause of the shoulder complications is unknown, and more research is mandatory to shed more light on the complex interplay between the multifactorial causes of shoulder dysfunction in diabetes mellitus.

Arthroscopy 2022; 38:1115-1123. [PMID: 34767955 DOI: 10.1016/j.arthro.2021.10.029] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/08/2021] [Revised: 10/18/2021] [Accepted: 10/19/2021] [Indexed: 02/02/2023]
Abstract
PURPOSE To build upon previous literature to identify a complete analysis of cellular contents of subacromial bursal tissue as well as the matrix surrounding the rotator cuff. METHODS Samples of subacromial bursal tissue and surrounding matrix milieu from above the rotator cuff tendon and above the rotator cuff muscle bellies were obtained from 10 patients undergoing arthroscopic rotator cuff repair. Samples were analyzed using fluorescent-activated cell sorting and histologic analysis with staining protocols (Oil Red O, Alcian Blue, and Picro-Sirius Red), for identification of matrix components, including fat, proteoglycans, and collagen. RESULTS Progenitor cells and fibroblast-type cells were present in significant amounts in subacromial bursal tissue in both tissues obtained from over the tendinous and muscle belly portions. Markers for neural tissue, myeloid cells, and megakaryocytes also were present to a lesser extent. There were prominent amounts of fat and proteoglycans present in the matrix, based on ImageJ analysis of stained histologic slides. CONCLUSIONS The subacromial bursal tissue and surrounding matrix of patients undergoing rotator cuff repair contains progenitor cells in significant concentrations both over the tendon and muscle belly of the rotator cuff. CLINICAL RELEVANCE This presence of progenitor cells, in particular, in the subacromial bursal tissue provides a potential basis for future applications of augmentation purposes in rotator cuff healing, and calls into question the practice of routine bursectomy. As the potential role of bursal tissue contents in growth and regeneration in the setting of rotator cuff healing is more well understood, maintaining this tissue may become more relevant. Concentration of these cellular components for use in autologous re-implantation is also an avenue of interest.

Abstract
Synovitis of the glenohumeral joint (GHJ) and subacromial space (SAS) is one of the most common findings during arthroscopic rotator cuff repair (RCR). The purpose of this study is to determine clinical factors associated with the degree of synovitis in patients with a rotator cuff tear and whether macroscopic synovitis affects early clinical outcomes following arthroscopic RCR. Arthroscopic videos of 230 patients treated with arthroscopic RCR were randomly reviewed by two experienced shoulder surgeons. The synovitis scores of the GHJ using Davis's grading system and the SAS using Jo's grading system were rated with a consensus. Univariate and multivariate analyses were used to identify the associations between the synovitis scores and various parameters, including demographics, preoperative, and postoperative clinical outcomes. Univariate analyses revealed that age, side, body mass index, duration of symptoms, preoperative stiffness, diabetes, muscle atrophy, fatty infiltration, tear size, preoperative clinical scores, and preoperative range of motion were significantly associated with the GHJ synovitis score (all p < 0.05). Multivariate analyses revealed that the duration of symptoms, tear size, and diabetes was significantly associated with the GHJ synovitis score (p = 0.048, p = 0.025, p = 0.011, respectively). Longer duration of symptoms, larger tear size, and the presence of diabetes was independently associated with increased GHJ synovitis in patients with a rotator cuff tear. These results suggest that GHJ synovitis might be more involved in the pathogenesis for pain and tear progression of rotator cuff disease compared with SAS synovitis.

Comparison of Clinical Outcomes between Idiopathic Frozen Shoulder and Diabetic Frozen Shoulder After a Single Ultrasound-Guided Intra-Articular Corticosteroid Injection. Diagnostics (Basel) 2020; 10:diagnostics10060370. [PMID: 32512719 PMCID: PMC7344419 DOI: 10.3390/diagnostics10060370] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2020] [Revised: 06/01/2020] [Accepted: 06/02/2020] [Indexed: 12/13/2022] Open
Abstract
There is no consensus on the use of intra-articular corticosteroid injections in diabetic frozen shoulder (FS). Thus, we aimed to compare clinical outcomes after intra-articular corticosteroid injections in patients with diabetic FS and idiopathic FS. Data collected from 142 FS patients who received glenohumeral joint intra-articular corticosteroid injections were retrospectively reviewed. Thirty-two patients were diagnosed with diabetic FS and 110 patients with idiopathic FS. Data including visual analog scale (VAS) for pain, American Shoulder and Elbow Surgeons (ASES) score, subjective shoulder value (SSV), and passive range of motion (ROM) were compared before the injection and at 3, 6, and 12 weeks after the injection. There were significant improvements in all outcomes (p < 0.001 for all parameters) through 12 weeks in both groups. There were no significant differences in all outcomes, except for ASES scores, between both groups at 3 weeks. However, there were significant differences in VAS score, SSVs, ASES scores, and passive ROMs, except for angle of abduction, between the two groups at 6 weeks and 12 weeks after injection. A single intra-articular steroid injection can be used as a conservative treatment for diabetic FS, but less effective than for idiopathic FS.

Abstract
INTRODUCTION Diabetic patients have been known to have a higher incidence of frozen shoulder. Arthroscopic capsular release has been described for diabetic frozen shoulder refractory to non-surgical treatment. We describe our single-surgeon experience of this procedure done in Asian patients presenting with diabetic frozen shoulder. RESULTS Data were prospectively collected from 25 patients from 2007 to 2008, who underwent arthroscopic capsular release for frozen shoulder with diabetes mellitus. This included the University of California-Los Angeles (UCLA) Shoulder Score by an independent observer. Mean follow-up duration was 44.3 ± 22 months with the age of 57.3 ± 10.9 years at the time of surgery. Mean duration of symptoms prior to surgery was 8.9 ± 7.5 months. Ten right shoulders and 15 left shoulders were operated on. Arthroscopic capsular release was performed in the beach chair position with the aid of a 90° electrocautery hook, from the rotator interval to posterior capsule. Significant improvement was observed in the UCLA scores post-operatively (preoperative total score 15.8 ± 3.6 vs. post-operative 33.3 ± 2.5, p < 0.00), including all domains of pain (3.9 ± 1.8 vs. 9.4 ± 0.9, p < 0.00), function (4.8 ± 1.7 vs. 9.4 ± 1.4, p < 0.00), active forward flexion (2.6 ± 0.7 vs. 4.6 ± 0.6, p < 0.00) and satisfaction (0.0 ± 0.0 vs. 5.0 ± 0.0, p < 0.00). No significant correlation between duration of symptoms and UCLA scores. Significant improvement was observed in forward flexion (preoperative 100.4 ± 18.8° vs. post-operative 157.6 ± 15.9°, p < 0.00) and external rotation (preoperative 14.4 ± 6.34° vs. post-operative 63.8 ± 8.3°, p < 0.00). Although the duration of symptoms correlated significantly with preoperative forward flexion ( r = 0.443 and p < 0.027), there was no significant correlation with post-operative forward flexion ( r = 0.023 and p < 0.91). No axillary nerve palsy observed. CONCLUSION The diabetic frozen shoulder can be treated favourably with arthroscopic capsular release and the duration of symptoms prior to surgery does not affect the outcomes.

Abstract
OBJECTIVE To compare dual-target injection with standard ultrasound (US)-guided subacromial injection in patients with subacromial impingement syndrome (SIS) and possible disorders of the biceps long-head tendons. DESIGN Double-blind, randomized controlled trial. SETTING Rehabilitation outpatient clinic. PARTICIPANTS Patients with SIS (N=60). INTERVENTION (1) US-guided standard subacromial bursa; (2) dual-target (subacromial bursa plus proximal biceps long-head tendon) injection, with 40-mg triamcinolone acetonide administered to patients in each group. MAIN OUTCOME MEASURES Clinical assessments were performed at baseline. The outcomes, including results from a self-administered questionnaire, the Shoulder Pain and Disability Index (SPADI), and a self-pain report, the visual analog scale (VAS) scores for pain at rest, at night, and during overhead activities, were evaluated at baseline and at the first and third months postintervention. RESULTS No significant difference was observed in baseline evaluations between groups (n=30 in each treatment arm) prior to injections. Both groups exhibited significant SPADI and VAS-score improvements after the first month. The dual-target injection group had less rebounding pain at the 3-month follow-up. The standard injection group had more patients reporting worsening pain within 1 day postinjection. CONCLUSION US-guided dual-target corticosteroid injection showed similar short-term efficacy to standard subacromial injections, but with an extended duration of symptom relief. Therefore, dual-target corticosteroid injections may be useful for shoulder pain treatment in patients with SIS.

Abstract
INTRODUCTION While the exact mechanism of primary adhesive capsulitis is unknown, we know that it has strong associations with diabetes mellitus (DM). Although self-limiting, a significant percentage of patients still have persistent pain and stiffness beyond 3 years. Arthroscopic capsular release (ACR) has been described as a successful intervention for recalcitrant adhesive capsulitis that provides early and long-term recovery. The aim of this study is to investigate the relationship between DM and ACR. METHODS We reviewed prospectively collected data of 56 consecutive patients with idiopathic frozen shoulder who underwent ACR (360° arthroscopic capsulotomy) under a single surgeon. Range of motion, pain score and shoulder function (Constant Shoulder Score, Oxford Shoulder Score, University of California Los Angeles Shoulder Score) were documented preoperatively and one year postoperatively. Patients were dichotomized into diabetic (n = 32) and non-diabetic patients (n = 24) and compared using a mixed ANOVA design to investigate for differences in outcomes. RESULTS Both group of patients had significant improvement in range of motion, reduced pain scores and improved shoulder scores one year postoperatively (p = 0.000). Diabetic patients had poorer internal rotation (p = 0.000), forward flexion (p = 0.035) and poorer postoperative Constant Shoulder score (p < 0.05). Otherwise both groups improved equally in all other aspects. CONCLUSION ACR offered good outcomes in both diabetic and non-diabetic patients in terms of range of motion, pain relief and shoulder function. However diabetic patients had poorer improvement in internal rotation and forward flexion postoperatively. Preoperative counselling and postoperative rehabilitation can be better tailored to treat diabetic patients with idiopathic adhesive capsulitis.

Abstract
The high incidence of degenerative tears and prevalence of retears (20-95%) after surgical repair makes rotator cuff injuries a significant health problem. This high retear rate is attributed to the failure of the repaired tissue to regenerate the native tendon-to-bone insertion (enthesis). Biological augmentation of surgical repair such as autografts, allografts, and xenografts are confounded by donor site morbidity, immunogenicity, and disease transmission, respectively. In contrast, these risks may be alleviated via growth factor therapy, which can actively influence the healing environment to promote functional repair. Several challenges have to be overcome before growth factor delivery can translate into clinical practice such as the selection of optimal growth factor(s) or combination, identification of the most efficient stage and duration of delivery, and the design considerations for the delivery device. Emerging insight into the injury-repair microenvironment and our understanding of growth factor mechanisms in healing are informing the design of advanced delivery scaffolds to effectively treat rotator cuff tears. Here, we review potential growth factor candidates, design parameters and material selection for growth factor delivery, innovative and dynamic delivery scaffolds, and novel therapeutic targets from tendon and developmental biology for the structural and functional healing of rotator cuff repair.

Abstract
Rotator cuff pathology is a significant cause of shoulder pain. Operative repair of rotator cuff is an established standard of care for these patient, however, failure of the procedure is common. Systemic conditions such as diabetes mellitus, hypocholesteremia, thyroid disease, and smoking significantly affect the outcomes of rotator cuff repair and have significant implications for the management of these patients. Diabetes mellitus has been proposed to damage tendons through non-enzymatic glycosylation of collagen with advanced glycation end product formation and impaired microcirculation. Hypocholesteremia may lead to fatty infiltration and subsequent pro-inflammatory degenerative enzymatic degeneration. Thyroid disease may disrupt tendon homeostasis through the alteration of collagen production and the accumulation of glycosaminoglycans. Lastly, smoking inhibits tendon healing through the induction of hypovascularity and hypoperfusion. Understanding of the implications these systemic conditions have on the outcomes is important in the management of rotator cuff disease.

Abstract
Background: Shoulder pathology can cause significant pain, discomfort, and loss of function that all interfere with activities of daily living and may lead to poor quality of life. Primary osteoarthritis and rotator cuff diseases with its sequalae are the main culprits. Management of shoulder disorders using biological factors gained an increasing interest over the last years. This interest reveals the need of effective treatments for shoulder degenerative disorders, and highlights the importance of a comprehensive and detailed understanding of the rapidly increasing knowledge in the field. Methods: This study will describe most of the available biology-based strategies that have been recently developed, focusing on their effectiveness in animal and clinical studies. Results: Data from in vitro work will also be briefly presented; in order to further elucidate newly acquired knowledge regarding mechanisms of tissue degeneration and repair that would probably drive translational work in the next decade. The role of platelet rich-plasma, growth factors, stem cells and other alternative treatments will be described in an evidence-based approach, in an attempt to provide guidelines for their clinical application. Finally, certain challenges that biologic treatments face today will be described as an initiative for future strategies. Conclusion: The application of different growth factors and mesenchymal stem cells appears as promising approaches for enhancing biologic repair. However, data from clinical studies are still limited, and future studies need to improve understanding of the repair process in cellular and molecular level and evaluate the effectiveness of biologic factors in the management of shoulder disorders.

J Diabetes Complications 2016; 30:1473-1477. [PMID: 27600100 DOI: 10.1016/j.jdiacomp.2016.07.015] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/19/2016] [Revised: 07/08/2016] [Accepted: 07/19/2016] [Indexed: 01/16/2023]
Abstract
BACKGROUND Rotator cuff tears are the most common cause of shoulder disability in people older than 50years, and surgical intervention is usually required for restoring functioning. However, in patients undergoing rotator cuff repair surgery, patients with DM had poorer functional outcomes than those without DM, and hence, DM is one of the possible risks factor for rotator cut off tear. The aim of this population-based study was to investigate the relationship between DM and the risk of rotator cuff tear in patients receiving rotator cuff repair surgery. METHODS In this retrospective longitudinal population-based 7-year cohort study, we investigated the risk of rotator cuff repair surgery in patients with DM. We performed a case-control matched analysis by using data from the Taiwan Longitudinal Health Insurance Database 2005. Patients were enrolled on the basis of the International Classification of Diseases, Ninth Revision, Clinical Modification diagnostic codes for DM between January 1, 2004, and December 31, 2007. The prevalence and the adjusted hazard ratios (HRs) of a rotator cuff repair surgery in patients with and without DM were estimated according to the Cox proportional hazard regression analysis using the frailty model. RESULTS The DM and non-DM cohorts comprised 58,652 patients with DM and 117,304 (1:2) patients without DM after matching for age and sex. The incidence of rotator cuff repair surgery was 41 per 100,000 and 26 per 100,000 person-years in the DM and non-DM cohorts, respectively. The HR of rotator cuff repair surgery during the follow-up period was 1.56 (95% confidence interval [CI] 1.25-1.93, p<0.001) for patients with DM. After adjustment for covariates, the adjusted HR of rotator cuff repair surgery was 1.33 (95% CI, 1.05-1.68, p<0.001) in the DM cohort. CONCLUSION DM is an independent risk factor for rotator cuff tear repair surgery.

Pietrzak M. Adhesive capsulitis: An age related symptom of metabolic syndrome and chronic low-grade inflammation? Med Hypotheses 2016; 88:12-7. [PMID: 26880627 DOI: 10.1016/j.mehy.2016.01.002] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2015] [Revised: 11/29/2015] [Accepted: 01/01/2016] [Indexed: 02/08/2023]
Abstract
Adhesive capsulitis (AC) is very poorly understood, particularly it's underlying etiology. Obesity and metabolic syndrome, which are strongly associated with chronic low grade inflammation, are becoming increasingly understood to underlie a raft of morbid states including upper limb pain syndromes, diabetes (DM), cardiovascular disease (CVD), cancer and central nervous system dysfunction and degeneration. Notwithstanding age, two of the strongest established risk factors for AC are DM and CVD. The hypothesis argues that similar to DM and CVD, the inflammation and capsular fibrosis seen in AC is precipitated by metabolic syndrome and chronic low grade inflammation. These pathophysiological mechanisms are highly likely to be perpetuated by upregulation of pro-inflammatory cytokine production, sympathetic dominance of autonomic balance, and neuro-immune activation. The hypothesis predicts and describes how these processes may etiologically underpin and induce each sub-classification of AC. An improved understanding of the etiology of AC may lead to more accurate diagnosis, improved management, treatment outcomes, and reduce or prevent pain, disability and suffering associated with the disease. The paper follows on with a discussion of similarities between the pathophysiology of AC to general systemic inflammatory control mechanisms whereby connective tissue (CT) fibrosis is induced as a storage depot for leukocytes and chronic inflammatory cells. The potential role of hyaluronic acid (HA), the primary component of the extracellular matrix (ECM) and CT, in the pathophysiology of AC is also discussed with potential treatment implications. Lastly, a biochemical link between physical and mental health through the ECM is described and the concept of a periventricular-limbic central driver of CT dysfunction is introduced.

Abstract
Frozen shoulder is a poorly understood condition that typically involves substantial pain, movement restriction, and considerable morbidity. Although function improves overtime, full and pain free range, may not be restored in everyone. Frozen shoulder is also known as adhesive capsulitis, however the evidence for capsular adhesions is refuted and arguably, this term should be abandoned. The aim of this Masterclass is to synthesise evidence to provide a framework for assessment and management for Frozen Shoulder. Although used in the treatment of this condition, manipulation under anaesthetic has been associated with joint damage and may be no more effective than physiotherapy. Capsular release is another surgical procedure that is supported by expert opinion and published case series, but currently high quality research is not available. Recommendations that supervised neglect is preferable to physiotherapy have been based on a quasi-experimental study associated with a high risk of bias. Physiotherapists in the United Kingdom have developed dedicated care pathways that provide; assessment, referral for imaging, education, health screening, ultrasound guided corticosteroid and hydro-distension injections, embedded within physiotherapy rehabilitation. The entire pathway is provided by physiotherapists and evidence exists to support each stage of the pathway. Substantial on-going research is required to better understand; epidemiology, patho-aetiology, assessment, best management, health economics, patient satisfaction and if possible prevention.

Abstract
The aim of the study was to determine the prevalence and factors associated with bursitis/tendonitis disorders in Puerto Ricans with diabetes mellitus (DM). A cross-sectional study was performed in 202 adult Puerto Ricans (100 DM patients and 102 non-diabetic subjects). For each participant, a complete medical history and a musculoskeletal exam were systematically performed. Socio-demographic parameters, health-related behaviors, comorbidities, and pharmacotherapy were determined for all subjects. For DM patients, disease duration, glycemic control, and DM long-term complications were also examined. Multivariate logistic regression analyses were used to determine the factors associated with bursitis/tendonitis disorders. The mean (SD) age for DM patients and non-diabetic controls were 53.3 (12.9) and 50.0 (13.1) years; 64.0 and 64.7 % of DM patients and controls were females, respectively. Overall, the prevalence of bursitis/tendonitis was higher in DM patients than among non-diabetics (59.0 % vs. 29.4 %, p < 0.01). In multivariate analyses, DM patients had 2.47 (95 % CI 1.05, 5.84) the odds of having bursitis/tendonitis as compared to non-diabetics. Specifically, DM patients had a higher frequency of flexor tenosynovitis, De Quervain's tenosynovitis, lateral epicondylitis, medial epicondylitis, trochanteric bursitis, and anserine bursitis than non-diabetic subjects (p < 0.05). Among DM patients, multivariate analyses showed that those with bursitis/tendonitis were more likely to be female [OR (95 % CI) 4.55 (1.42, 14.55)] and have peripheral vascular disease [OR (95 % CI) 8.48 (1.71, 41.93)]. In conclusion, bursitis/tendonitis disorders were common in this population of Hispanics with DM. Among DM patients, bursitis/tendonitis disorders were more frequent in women and those with long-term complications such as peripheral vascular disease.

Abstract
OBJECTIVE Although it has been suggested that diabetes mellitus (DM) is a risk factor for developing adhesive capsulitis of the shoulder (ACS), data on the temporal association between these 2 conditions are sparse. The purpose of this population-based age- and sex-matched cohort study was to investigate the risk of developing ACS in patients with newly diagnosed DM. METHODS A total of 78,827 subjects with at least 2 ambulatory care visits with a principal diagnosis of DM in 2001 were recruited for the DM group. The non-DM group comprised 236,481 age- and sex-matched randomly sampled subjects without DM. The 3-year cumulative risk of ACS was calculated using the Kaplan-Meier method. A Cox proportional hazards regression model was used to estimate the crude and adjusted hazard ratio (HR) of developing ACS. RESULTS During a 3-year followup period, 946 subjects (1.20%) in the DM group and 2,254 subjects (0.95%) in the non-DM group developed ACS. The crude HR of developing ACS for the DM group compared to the non-DM group was 1.333 (95% confidence interval [95% CI] 1.236-1.439, P < 0.0001), whereas the adjusted HR was 1.321 (95% CI 1.224-1.425, P < 0.0001) after adjustment for age, sex, and dyslipidemia. CONCLUSION This longitudinal population-based followup study showed that there is a significantly increased risk of developing ACS after developing DM.

Abstract
OBJECTIVE To discuss the treatment of a patient with type 1 diabetes presenting with chronic neck and shoulder pain by using chiropractic manipulation and an active rehabilitation program with emphasis on correcting postural imbalances. CLINICAL FEATURES A 46-year-old insulin dependant (type1) diabetic female presented with neck and right shoulder pain of 6 to 8 months duration. Her history included similar left-sided complaints 2 years prior at which time she underwent 3 months of rehabilitation at a local medical center, which improved her condition. Over time her pain resolved but the residuals of restricted left shoulder range of motion remained. The patient had postural changes consisting of forward head posture, rounded shoulders and internally rotated arms. INTERVENTION AND OUTCOME Treatment included spinal manipulation, ultrasound and active rehabilitation consisting of at home exercises initially and followed with in office low-tech rehabilitation. Rehabilitation was primarily aimed at improving postural abnormalities, muscle imbalances and abnormal movement patterns. The patient improved with this course of treatment. CONCLUSION Chiropractic care including active rehabilitation may be helpful in treating diabetic patients suffering from chronic neck and shoulder problems.

Abstract
We analysed the possibility that some blood values could be considered as a prognostic index of shoulder adhesive capsulitis. Fifty-six conservatively treated patients were clinically evaluated and prospectively followed at the moment of their freezing phase. At the beginning of the disease (time 0) and after 4 months (time 1), we registered some blood parameters values and their Constant Score (CS). Differences emerged for the white blood cell count (P = 0.037) that decreased and for the CS (P < 0.00001) that increased. At time 0, no significant correlation emerged between the studied parameters and the CS. At time 1, significant inverse correlations with the CS were found for glycaemia (P = 0.007), triglycerides (P = 0.05), ESR (P = 0.017) and CRP (P = 0.013). At time 1, patients with a better shoulder function were those with a low value of glycaemia, triglycerides, ESR and CRP.

Abstract
Background The prevalence of rotator cuff tears increases with age and several studies have shown that diabetes is associated with symptomatic shoulder pathologies. Aim of our research was to evaluate the prevalence of shoulder lesions in a population of asymptomatic elderly subjects, normal and with non insulin - dependent diabetes mellitus. Methods The study was performed on 48 subjects with diabetes and 32 controls (mean age: 71.5 ± 4.8 and 70.7 ± 4.5, respectively), who did not complain shoulder pain or dysfunction. An ultrasound examination was performed on both shoulders according to a standard protocol, utilizing multiplanar scans. Results Tendons thickness was greater in diabetics than in controls (Supraspinatus Tendon: 6.2 ± 0.09 mm vs 5.2 ± 0.7 mm, p < 0.001; Biceps Tendon: 4 ± 0.8 mm vs 3.2 ± 0.4 mm, p < 0.001). Sonographic appearances of degenerative features in the rotator cuff and biceps were more frequently observed in diabetics (Supraspinatus Tendon: 42.7% vs 20.3%, p < 0.003; Biceps Tendon: 27% vs 7.8%, p < 0.002). Subjects with diabetes exhibited more tears in the Supraspinatus Tendon (Minor tears: 15 (15.8%) vs 2 (3.1%), p < 0.03; Major tears: 15 (15.8%) vs 5 (7.8%), p = ns), but not in the long head of Biceps. More effusions in subacromial bursa were observed in diabetics (23.9% vs 10.9%, p < 0.03) as well as tenosynovitis in biceps tendon (33.3% vs 10.9%, p < 0.001). In both groups, pathological findings were prevalent on the dominant side, but no difference related to duration of diabetes was found. Conclusions Our results suggest that age - related rotator cuff tendon degenerative changes are more common in diabetics. Ultrasound is an useful tool for discovering in pre - symptomatic stages the subjects that may undergo shoulder symptomatic pathologies.

Abstract
It is still unclear whether diabetic mellitus (DM) is associated with rotator cuff lesions. The object of this retrospective study was to compare the ultrasonographic (US) findings of rotator cuffs in diabetic patients with those of nondiabetic patients with chronic shoulder pain. In total, 419 patients (80 diabetic, 339 nondiabetic) who had chronic shoulder pain and had been referred to receive US examination between January 2005 and January 2008 in a medical center were included in this study. The US findings of rotator cuff lesions were classified into two main categories: rotator cuff tears (RCTs) and calcifying tendinopathy (CT). In total, 114 (25.2%) shoulders with CT of the rotator cuff and 160 (35.3%), 15 (3.3%) and 5 (1.1%) shoulders with supraspinatus, infraspinatus and subscapularis tears, respectively, were noted. No difference in the ratio of tears of RCTs was found on US examinations between two groups. The crude odds ratio (OR) for CT of diabetic patients was 1.85 (p = 0.014); however, the adjusted OR for CT in diabetic patients became insignificant after controlling for the other variables (OR = 1.59, p = 0.08). To our knowledge, this is the first study to explore US findings among diabetic and nondiabetic patients with chronic shoulder pain. Further study is advised to confirm our findings.

Abstract
The purpose of this study was to investigate neovascularization and the expression of vascular endothelial growth factor (VEGF) in patients with diabetic frozen shoulders. Eleven patients with diabetic frozen shoulders underwent arthroscopic lysis of adhesions, and we observed the reported findings. VEGF expression was determined by immunohistochemistry and Western blot analysis, and the density of vessels was evaluated based on CD34 immunoreactivity by use of samples of the synovial tissue. For the control group, we took 5 samples of synovium from patients undergoing shoulder arthroscopy. The arthroscopic findings showed hyperemia of the synovial tissue in all cases of diabetic frozen shoulder. This synovium showed stronger immunostaining to VEGF (P = .010) and CD34 (P = .011) than the control synovial tissue. Western blot analysis also showed a stronger VEGF intensity than in the control group. We postulate that VEGF is synthesized and secreted in the synovium of diabetic frozen shoulders and VEGF may have some role in the pathogenesis and neovascularization of frozen shoulders in diabetic patients.
