Influence of diabetes on response to ultrasound guided hydrodistension treatment of adhesive capsulitis: a retrospective study

BACKGROUND

Diabetes is associated with microvascular and macrovascular complications. Although it is less recognized, diabetes also has an important role in the development of musculoskeletal disorders. Our objective was to evaluate the effect of type 2 diabetes (T2D) on the severity of adhesive capsulitis of the shoulder (AC) and on the efficacy of ultrasound guided hydrodistension treatment.

METHODS

We conducted a retrospective longitudinal observational study, of patients with AC who underwent ultrasound guided hydrodistension at our Centre. Severity was measured with DASH (Disabilities of Arm, Shoulder and Hand) score and pain was evaluated with a score between 0 and 10. The association of T2D with baseline characteristics of AC, and with outcomes at 6-12 months was analyzed using linear and logistic regression models.

RESULTS

We evaluated 120 ultrasound guided hydrodistension treatments of AC, 85 in patients without diabetes and 35 in patients with T2D. Patients with diabetes had a higher prevalence of dyslipidemia, hypertension and higher HbA1c values. The average duration of diabetes was 4.8 years (2.0, 7.9). The baseline characteristics of AC were not significantly different between patients with and without diabetes. Patients with T2D relapsed more frequently and required more reinterventions than patients without diabetes (20.0% vs 4.7%, p = 0.008), had higher post-intervention pain scale values [4.0 (0.0-5.0) vs 0.0 (0.0-5.0), p = 0.022] and higher post-intervention DASH score [0.8 (0.0-1.8) vs 0.0 (0.0-0.8), p = 0.038].

CONCLUSION

Although baseline characteristics of AC in patients with diabetes were similar to those without diabetes, patients with diabetes had a worse response to treatment, more frequent relapses and a greater need for new interventions.

Causes of Shoulder Dysfunction in Diabetic Patients: A Review of Literature

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.

Effect of diabetes and corticosteroid injection on glenohumeral joint capsule in a rat stiffness model

PURPOSE

To evaluate the effects of diabetes and corticosteroid injected in the joints on the shoulder motion, gait, and joint capsular properties in a rat stiffness model.

METHODS

A total of 27 rats were randomly distributed into 3 groups-nondiabetes group (group A), diabetes group (group B), and diabetes plus steroid injection group (group C). The diabetes model was developed by inducing hyperglycemia with a submaximal dose of streptozotocin and the stiffness model by completely immobilizing the right shoulder of each animal in all groups with sutures passed between the scapula and humeral shaft. The left shoulder was used as an untreated control in all groups. Three weeks after immobilization, the sutures were removed in all groups, and a single dose of triamcinolone acetonide (0.5 mg/kg) was injected into the glenohumeral joint in group C. After 3 weeks of free activity, range of motion (ROM) evaluation, gait analysis by stride length, and capsular area measurement were performed in all rats.

RESULTS

Hyperglycemia was successfully induced with a mean blood glucose level of 448.9±55.9 mg/dL in group B and 431.6±17.8 mg/dL in group C, which were significantly higher than 136.5±13.4 mg/dL in group A (P < .001). A significantly smaller ROM and stride length were found in the right (stiffness-induced) shoulder than that in the left (control) shoulder only in group B, and significantly larger capsular area in the right shoulder than that in the left shoulder in groups A and B (all P < .05). However, in group C, there were no differences between the right and left shoulders in all measurements (all P > .05). In case of the right shoulders in each group, group C showed significantly larger ROM (68° ± 11° vs. 42° ± 7°) and smaller capsular area (3934.4 ± 537.1 pixels vs. 7402.3 ± 1840.3 pixels) than group B (all P < .0167).

CONCLUSIONS

The diabetic model had a detrimental effect on the development of stiffness by thickening the joint capsule, and an intra-articular steroid injection resolved the thickened joint capsule and restored shoulder motion.

Idiopathic Frozen Shoulder in Individuals with Diabetes: Association with Metabolic Control, Obesity, Antidiabetic Treatment and Demographic Characteristics in Adults with Type 1 or 2 Diabetes from the DPV Registry

AIMS

To examine the association of frozen shoulder (FS) with demographic and diabetes-related outcomes in individuals with type 1 (T1D) or type 2 (T2D) diabetes aged ≥30 years.

MATERIALS AND METHODS

Multivariable logistic regression models, adjusted for demographics were used to calculate the proportion of FS in association with age, gender, diabetes duration, body mass index (BMI), haemoglobin A1C (HbA1c) and diabetes treatment.

RESULTS

The unadjusted percentage of FS was higher in T1D compared to T2D (0.22% vs. 0.06%). In T1D, adjusted regression models revealed higher prevalence of FS in women than men (0.26 [0.20-0.34] % vs. 0.15 [0.11-0.21] %, p=0.010). No significant relationship of age and BMI with FS was found in both diabetes types. Longer diabetes duration was associated with a higher proportion of FS in T1D (p<0.001) and T2D (p=0.004). In T1D, HbA1c >7% was related to a higher proportion of FS compared to HbA1c ≤7% (0.25 [0.19-0.32] vs. 0.12 [0.08-0.20] %, p=0.007), while an inverse relationship was found in T2D (HbA1c ≤7%: 0.08 [0.07-0.10] vs. HbA1c >7%: 0.05 [0.04-0.06] %, p=0.001).

CONCLUSIONS

Different associations of FS with gender and HbA1c were observed for T1D and T2D; however, longer diabetes duration increases the risk for FS independent of diabetes type. Musculoskeletal diseases are still underreported in individuals with diabetes and awareness should be raised for FS as a specific diabetes complication.

Diabetes: a silent player in musculoskeletal interventional radiology response

Diabetes has an important role in the development of several musculoskeletal disorders, such as adhesive capsulitis of the shoulder (ACs) and stenosing flexor tenosynovitis of the finger (SfTf). The etiopathophysiology of ACs and SfTf in diabetic patients is associated with both chronic hyperglycemia, increased amounts of visceral adiposity and chronic inflammation. Chronic hyperglycemia stimulates the creation of cross-links between collagen molecules, impairing degradation and resulting in the build-up of excessive collagen deposits in the cartilage, ligaments, tendon sheaths and tendons. Increased adipocytes in diabetic patients secrete proteins and cytocines such as TNF-α, IL-6 and IL-13 which result in overproduction of pro-inflammatory factors, destruction of normal tissue architecture and fibrosis. Both hyperglycemia and adipocytes inhibit efferocytosis, limiting natural resolution. Recently, multiple image-guided interventional radiology musculoskeletal treatment options have been developed, such as ultrasound-guided glenohumeral capsule hydrodistension for ACs and ultrasound-guided percutaneous pulley release for trigger finger. Diabetes can negatively influence outcomes in patients with ACs and SfTf and may impact the decision of which specific procedure technique should be employed. Further studies are necessary to define how diabetes influences response to interventional radiology treatments of these disorders, as well as the extent to which control of blood sugar levels can contribute towards the personalization and optimization of patient follow up.

Frozen Shoulder: A Systematic Review of Cellular, Molecular, and Metabolic Findings

BACKGROUND

Frozen shoulder is a common, poorly understood condition affecting the shoulder joint, with poor long-term outcomes in some in relation to pain and mobility. Understanding the pathophysiology of frozen shoulder at a cellular level and a molecular level may help in the development of novel treatments. The aim of this study was to perform a systematic review of studies examining the cellular, molecular, and metabolic findings in frozen shoulder.

METHODS

A literature search was conducted using Embase, CINAHL (Cumulative Index of Nursing and Allied Health Literature), and PubMed using relevant terms. Studies were included if they assessed cellular, molecular, or metabolic alterations in tissue or blood samples of patients with frozen shoulder.

RESULTS

Of 4,794 studies identified, 25 were included for analysis. Histological findings included nonspecific chronic inflammation and the proliferation of fibroblasts, adipocytes, and blood vessels. Molecular studies showed increased pro-inflammatory mediators, reduced matrix metalloproteinases (MMPs), and increased activity of factors promoting fibroblast activation and nerve growth. Metabolic alterations included an increase in blood lipids.

CONCLUSIONS

Frozen shoulder is thought to occur after a primary insult to the shoulder triggers a complex cascade and upregulation of growth factors and cytokines with an increased turnover of the extracellular matrix, activation of myofibroblasts with deposition of collagen, and reduced matrix degradation. The presence of a background pro-inflammatory state (e.g., patients with diabetes or hyperlipidemia) may exacerbate these abnormalities. Further work assessing patients in early stages of the disease and comparing the inflammatory or fibrogenic characteristics of the shoulder capsule with those of the other joints may help to determine the initiating factors and to explain the predisposition of the shoulder to stiffness.

CLINICAL RELEVANCE

Our findings may form the basis for identifying new targets for the clinical management of frozen shoulder.

The presence of gastroesophageal reflux disease increases the risk of developing postoperative shoulder stiffness after arthroscopic rotator cuff repair

BACKGROUND

Postoperative shoulder stiffness (SS) after arthroscopic rotator cuff (RC) repair has been reported with a variable incidence, and numerous preoperative risk factors have been described. This prospective study aimed to document the incidence of postoperative SS and to evaluate the role of preoperative risk factors in the development of this complication, with a special focus on the role of gastroesophageal reflux disease (GERD).

METHODS

Preoperative risk factors for SS were prospectively evaluated in 237 consecutive patients undergoing arthroscopic single-row RC repair. The presence of GERD was evaluated with the GerdQ diagnostic tool. Postoperative SS was diagnosed according to the criteria described by Brislin et al in 2007.

RESULTS

The incidence of postoperative SS was 8.02%. The presence of GERD was significantly associated with the development of postoperative SS (odds ratio [OR], 5.265; 95% confidence interval [CI], 1.657-1.731; P = .005). Older age (OR, 0.896; 95% CI, 0.847-0.949; P < .001), male sex (OR, 0.126; 95% CI, 0.0252-0.632; P = .012), and number of pregnancies (OR, 0.47; 95% CI, 0.228-0.967; P = .040) emerged as protective factors.

CONCLUSIONS

The presence of GERD significantly influences the development of postoperative SS after arthroscopic single-row RC repair. An underlying aspecific proinflammatory condition, characterized by increased expression of tumor necrosis factor α and transforming growth factor β, and disorders in retinoid metabolism are hypotheses that could explain this previously unknown association. The documented incidence of postoperative SS falls within previously reported ranges, with women being significantly more affected than men.

Is it necessary to screen patient with adhesive capsulitis of shoulder for diabetes mellitus?

BACKGROUND

Idiopathic adhesive capsulitis of shoulder is common cause of pain and restriction of shoulder motion between the ages of 30 and 65. The prevalence of adhesive capsulitis is as high as 10% to 22% in diabetes mellitus as compared normal population which is 02% and 04%. Therefore, the doubt arises whether patients developed adhesive capsulitis are at greater risk to develop diabetes mellitus and should be screen for diabetes so that it can be detected early.

PURPOSE

To compare the prevalence of prediabeties and diabetes mellitus among patients with features of idiopathic adhesive capsulitis of shoulder who are otherwise healthy.

METHODS

Patients between 30-65 years of age who attended Orthopaedics OPD with features of idiopathic adhesive capsulitis of shoulder were included. Participated underwent a 2 hour long oral glucose tolerance test and based on fasting and 2-hour plasma glucose levels, patients were diagnosed as normal glucose tolerance, prediabetic, or diabetic and the results were matched with previous published data.

RESULTS

135 patients as participated and completed the test. 21 (15.5%) patients with idiopathic adhesive capsulitis of shoulder were found to be prediabetic, and 37 (27.4%) patients were found to be diabetic. However, 31 patients had family history of diabetes.

CONCLUSION

Based on our study, we can recommend that patients with features of idiopathic adhesive capsulitis of shoulder should be screened at least for fasting and post prandial blood sugar so that diabetes can be detected early.

Adhesive capsulitis of the shoulder and diabetes: a meta-analysis of prevalence

BACKGROUND

adhesive capsulitis (AC) results in progressive painful restriction in range of movement and can reduce function and quality of life. Whilst it has been associated with diabetes mellitus (DM), there is considerable variation in the reported prevalence of AC in the diabetic population. The aim of this study is to determine through meta-analysis the prevalence of AC in DM and examine whether it is influenced by type of DM or insulin therapy. We also aim to further establish the prevalence of DM in patients presenting with AC.

METHODS

we conducted a literature search for terms regarding AC and DM on Embase and Pubmed NCBI.

RESULTS

of 5411 articles identified, 18 were selected. Meta-analysis showed that patients with DM were 5 (95% CI 3.2-7.7) times more likely than controls to have AC. The overall prevalence of AC in DM was estimated at 13.4% (95% CI 10.2-17.2%). Comparison of prevalence in patients on insulin vs other treatments showed no significant difference between the two. Meta-analysis estimated the prevalence of DM in AC at 30% (95% CI 24-37%).

CONCLUSION

to our knowledge this is the first meta-analysis to estimate the overall prevalence of diabetes in a population with AC. A high prevalence of AC exists in DM and equally a high prevalence of DM is present in AC. Screening for DM should be considered in patients presenting with AC.

Frozen shoulder contracture syndrome - Aetiology, diagnosis and management

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.

Association of diabetes mellitus with the risk of developing adhesive capsulitis of the shoulder: a longitudinal population-based followup study

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.
