Ultrasound-Guided Pes Anserine Bursitis Injection Choices: Prolotherapy or Oxygen-Ozone or Corticosteroid: A Randomized Multicenter Clinical Trial.

OBJECTIVE: Pes anserine bursitis is the most common cause of periarticular knee pain. The aim of the study was to evaluate the efficacy of local injection-based therapies with different materials. DESIGN: The enrolled patients were randomly allocated to three groups to receive different interventions. Outcome measures included pain severity using the visual analog scale and the Western Ontario and McMaster Universities osteoarthritis index that was evaluated before the intervention, 1 and 8 wks after that. RESULTS: This trial was performed on 72 participants, with male-to-female ratio of 0.14 and with a mean age of 61.49 ± 9.35 yrs. Corticosteroids in the first group, oxygen-ozone in the second group, and dextrose 20% in the third group, were injected into the pes anserine bursa under ultrasound guidance. Interaction between time and group showed a statistically significant improvement in visual analog scale and Western Ontario and McMaster Universities Arthritis Index ( P ≤ 0.05) in favor of corticosteroids and oxygen-ozone groups after 1 wk and in favor of oxygen-ozone and prolotherapy groups after 8 wks. CONCLUSIONS: All three treatment options are effective for patients with pes anserine bursitis. This study showed that the effects of oxygen-ozone injection and prolotherapy last longer than those of corticosteroid injection.

A multi-center, single-blinded, randomized, parallel-group, superiority study to compare the efficacy of manipulation under anesthesia versus intra-articular steroid injection in the treatment of patients with frozen shoulder and a diagnosis of rotator cuff injury or tear by MRI: study protocol for a randomized controlled trial.

BACKGROUND: Frozen shoulder (FS) is a common condition that can cause severe pain and limited range of motion in the shoulder joint. While intra-articular steroid injection has been shown to be an effective treatment for FS, manipulation under anesthesia (MUA) is an alternative treatment that has gained popularity in recent years. However, there is a lack of evidence regarding the effectiveness of MUA on FS patients with concomitant rotator cuff injury or tear. Though a few studies have shown that MUA is not associated with rotator cuff tears, and will not exacerbate the injury, more high-quality studies with bigger sample sizes are needed. Therefore, the aim of this multi-center, single-blinded, randomized, parallel-group, superiority study is to compare the efficacy of MUA versus intra-articular steroid injection in the treatment of FS patients with a diagnosis of rotator cuff injury or tear by MRI. METHODS: A parallel, single-blinded, multi-center randomized controlled trial of 320 patients will be conducted at three hospitals of China. Eligible patients with frozen shoulder and rotator cuff injury or tear diagnosed by MRI will be randomly assigned to, in equal proportions, the manipulation under anesthesia group and the intra-articular steroid injection group via a central randomization system, undergoing a corresponding operation on day one and a sequent physical exercise for 14 days. The primary outcome is the comprehensive efficacy evaluation (total effective rate) and the change of Constant-Murley Score. Outcome assessors and data analysts will be blinded, and participants will be asked not to reveal their allocation to assessors. DISCUSSION: This study aims to explore the superiority of manipulation under anesthesia in reducing pain and improving shoulder function in frozen shoulder patients accompanied with rotator cuff injury. To provide a scientific basis for the dissemination and application of manipulation under anesthesia, and a better knowledge for the role of MUA in the treatment of frozen shoulder accompanied with rotator cuff injury.

Tuina in a Frozen Shoulder Rat Model: An Efficient and Reproducible Protocol.

Frozen shoulder (FS) is a common condition with no defined optimal therapy. Tuina therapy, a traditional Chinese medicine (TCM) technique used to treat FS patients in Chinese hospitals, has demonstrated excellent results, but its mechanisms are not fully understood. Building on a previous study, this work aimed to develop a Tuina protocol for an FS rat model. We randomly divided 20 SD rats into control (C; n = 5), FS model (M; n = 5), FS model Tuina treatment (MT; n = 5), and FS model oral treatment (MO; n = 5) groups. This study used the cast immobilization method to establish the FS rat model. The effect of Tuina and oral dexamethasone on the glenohumeral range of motion (ROM) was evaluated, and the histological findings were assessed. Our study showed that Tuina and oral dexamethasone were able to improve shoulder active ROM and preserve the structure of the capsule, with Tuina therapy proving to be more effective than oral dexamethasone. In conclusion, the Tuina protocol established in this study was highly effective for FS.

Comparison Clinical Effects of Hypertonic Dextrose and Steroid Injections on Chronic Subacromial Bursitis: A Double-Blind Randomized Controlled Trial.

OBJECTIVE: The aim of the study is to determine and compare the treatment efficacy of subacromial steroid injections and dextrose prolotherapy for chronic subacromial bursitis patients. DESIGN: Fifty-four patients with chronic subacromial bursitis were enrolled in this double-blind randomized controlled trial. Shoulder Pain and Disability Index and visual analog scale were the primary outcomes. RESULTS: The steroid group ( n = 26) exhibited significant visual analog scale score improvements comparing with baseline at weeks 2, 6, and 12; the dextrose prolotherapy group ( n = 28) exhibited visual analog scale score improvements at weeks 6 and 12. The steroid group displayed significant Shoulder Pain and Disability Index score improvements compared with baseline at weeks 2, 6, and 12; the dextrose prolotherapy group exhibited significant score decreases at weeks 2 and 6. Compared with the dextrose prolotherapy group, the steroid group demonstrated significantly greater decreases in visual analog scale scores at weeks 2 and 6; the steroid group showed significantly greater decreases in Shoulder Pain and Disability Index scores at weeks 2, 6, and 12. CONCLUSIONS: Both hypertonic dextrose prolotherapy and steroid injections can provide short-term improvements of pain and disability among chronic subacromial bursitis patients. Moreover, steroid injections showed better effectiveness than hypertonic dextrose prolotherapy in ameliorating pain and improving function.

Effects of Hyperosmolar Dextrose Injection in Patients With Rotator Cuff Disease and Bursitis: A Randomized Controlled Trial.

OBJECTIVE: To determine whether dextrose prolotherapy offers clinical benefits in patients with shoulder pain and bursitis. DESIGN: Double-blinded, randomized controlled trial. SETTING: Outpatient rehabilitation department of a single medical center. PARTICIPANTS: Patients (N=50) who had received a diagnosis of shoulder pain and bursitis through clinical tests and ultrasound examination. INTERVENTIONS: Participants were randomly assigned to the 15% dextrose injection (D15W) group or the placebo group to receive either D15W or normal saline injection, respectively. All participants received ultrasound-guidance bursal injection every 2 weeks for a total of 3 injections. MAIN OUTCOME MEASURES: The primary outcome was maximal pain level while performing activities. The secondary outcomes included resting pain level, function and disability assessment results, and ultrasonographic parameters. Participants were followed up for 3 months after completion of the injection course. RESULTS: No significant differences in baseline characteristics were observed between the D15W and placebo groups. Significant time effects were observed for all outcome parameters (all P<.05); however, time × group effects were nonsignificant for all outcomes, except for tissue elasticity (P=.026). CONCLUSIONS: Supporting evidence is insufficient regarding the clinical benefits of 15% dextrose bursal injection administered through 3 sessions in patients with chronic shoulder pain and bursitis. The findings indicate that these injections may increase the tissue stiffness of the supraspinatus tendon, as indicated by elastography assessment results, but further research is required to determine the nature of such changes in elastography findings.

Intra-articular steroid for adhesive capsulitis: does hydrodilatation give any additional benefit? A randomized control trial.

OBJECTIVES: To assess the benefit offered by capsular hydrodilatation in addition to intra-articular steroid injections in cases of adhesive capsulitis, assess outcomes in diabetic patients with capsular hydrodilatation as compared to non-diabetics and correlate duration of symptoms with outcome based on the type of intervention given. MATERIALS AND METHODS: This prospective double-blinded randomized control trial included patients presenting with clinical features of adhesive capsulitis with no evidence of rotator cuff pathology and randomized them into two groups-intra-articular steroid with hydrodilatation (distension group) and only intra-articular steroid (non-distension group) with intervention being performed as per the group allotted. Primary outcome measure was Shoulder Pain and Disability Index (SPADI) scores which were taken pre-intervention, at 1.5, 3 and 6 months post-intervention, which were assessed by generalized linear model statistics and Pearson correlation. RESULTS: Although there was statistically significant drop in SPADI in both groups over time [F(1.9, 137.6) = 112.2; p < 0.001], mean difference in SPADI between the 2 groups was not statistically significant (1.53; CI:-3.7 to 6.8; p = 0.56). There was no significant difference between both groups among diabetics [F(1,38) = 0.04; p = 0.95] and no significant difference between diabetic and non-diabetic patients who received hydrodilatation [F(1.8, 60) = 2.26; p = 0.12]. There was no significant correlation between the reduction in SPADI scores and duration of symptoms in any subset of the study population. CONCLUSION: Shoulder joint hydrodilatation offered no additional benefit compared to intra-articular steroid injections for shoulder adhesive capsulitis. Outcome for diabetics and non-diabetics were similar and there was no correlation between duration of symptoms and outcome.

Dry Needling Versus Cortisone Injection in the Treatment of Greater Trochanteric Pain Syndrome: A Noninferiority Randomized Clinical Trial.

Study Design Prospective, randomized, partially blinded. Background Greater trochanteric pain syndrome (GTPS) is the current terminology for what was once called greater trochanteric or subgluteal bursitis. Cortisone (corticosteroid) injection into the lateral hip has traditionally been the accepted treatment for this condition; however, the effectiveness of injecting the bursa with steroids is increasingly being questioned. An equally effective treatment with fewer adverse side effects would be beneficial. Objective To investigate whether administration of dry needling (DN) is noninferior to cortisone injection in reducing lateral hip pain and improving function in patients with GTPS. Methods Forty-three participants (50 hips observed), all with GTPS, were randomly assigned to a group receiving cortisone injection or DN. Treatments were administered over 6 weeks, and clinical outcomes were collected at baseline and at 1, 3, and 6 weeks. The primary outcome measure was the numeric pain-rating scale (0-10). The secondary outcome measure was the Patient-Specific Functional Scale (0-10). Medication intake for pain was collected as a tertiary outcome. Results Baseline characteristics were similar between groups. A noninferiority test for a repeated-measures design for pain and averaged function scores at 6 weeks (with a noninferiority margin of 1.5 for both outcomes) indicated noninferiority of DN versus cortisone injection (both, P<.01). Medication usage (P = .74) was not different between groups at the same time point. No adverse side effects were reported. Conclusion Cortisone injections for GTPS did not provide greater pain relief or reduction in functional limitations than DN. Our data suggest that DN is a noninferior treatment alternative to cortisone injections in this patient population. Level of Evidence Therapy, level 1b.

Infiltration is a therapeutic option used for the treatment of various diseases, which comprises injected administration into precise locations of different substances. They may have an analgesic and / or anti-inflammatory and healing effect. Its use is common in the treatment of many soft tissue injuries such as bursitis, synovitis, plantar fasciitis, sprains, muscle injuries, tendinopathies and chondral injuries and must be preceded by the appropriate diagnosis. Almost all local infiltrations have mild side effects and, sometimes, these may be systemic and may have some specific contraindications depending on the administered substance. Most of the adverse effects are caused by improper use of the drug. The most used active substances are: local anesthetics that produce immediate pain relief, such as lidocaine and bupivacaine. They can be used alone or in combination with corticosteroids producing an immediate analgesic combined effect on local pain and a therapeutic effect of longer duration. Corticosteroids, whose main property is a very powerful anti-inflammatory action. The most used are betamethasone, methylprednisolone and triamcinolone. Hyaluronic acid, used in the treatment of joint diseases, particularly knee osteoarthritis and chondromalacias/chondropathias . It lubricates joints and appears to have direct effects on the function of synovial cells and synovial fluid. Sclerotherapy, which is the introduction of a chemical substance in the light of the blood vessels, causing obliteration and secondary fibrosis. It is indicated mainly in tendinopathies with vascular proliferation. Biorregulators: They stimulate healing when modulate or activate various involved substances. Platelet-rich plasma: autologous plasma containing more platelet concentration that normal blood, secreting a large amount of growth factors. Prolotherapy, it consists in substances infiltration that stimulate regeneration and tissue repair. Other: Nonsteroidal anti-inflammatory drugs, growth factors, stem cells and related therapies

[Polymyalgia rheumatica update, 2015]. / Polymyalgia rheumatica update, 2015.

Polymyalgia rheumatica is an inflammatory musculoskeletal disorder of people aged 50 years or over, characterised by pain, aching and morning stiffness in the shoulder girdle and often hip girdle and neck. Marked systemic inflammation and rapid response to corticosteroid therapy are characteristic features. Giant cell arteritis is a well-known association of polymyalgia rheumatica. Recent clinical evidence and scientific results in the field have provided new challenges for rheumatologists. Besides the aspecific - although characteristic - proximal syndrome, less well recognizable and more variable distal musculoskeletal manifestations were observed. Magnetic resonance and ultrasound studies showed mild, remitting and non-erosive synovitis, with dominating inflammation of the extraarticular synovial structures. As no pathognostic sign is known, the diagnosis of polymyalgia rheumatica is based on its differential diagnosis, differentiation from the polymyalgia mimics; particularly from elderly onset inflammatory arthritides, such as elderly onset rheumatoid arthritis and late onset seronegative spondylarthritis. In 2012 the international polymyalgia rheumatica work group under the guidance of the American College of Rheumatology and European League Against Rheumatism elaborated new classification criteria, the scoring algorythm of which is based on clinical symptoms, with ultrasonography increasing the specificity. Corticosteroids remain the cornerstone of the therapy of polymyalgia rheumatica. No effective steroid-sparing drug has been found to date. Corticosteroids are generally needed for 1-1.5 years, though some patients have a chronic-relapsing course and require corticosteroids for several years. Well known corticosteroid-related side effects (diabetes, hypertension, hyperlipidaemia and osteoporosis) cause significant morbidity and economic burden on the society. Novel therapeautic approaches are on trial. Early recognition of the disease, early start of corticosteroids and a well-defined course, prevention and management of side effects are everyday tasks for rheumatologists and family doctors. Knowledge of polymyalgia rheumatica is essential for all medical specialties.

[Outbreak of lead poisoning associated with Ayurvedic medicine]. / Brote de saturnismo asociado a un tratamiento basado en la medicina ayurvédica.

BACKGROUND AND OBJECTIVE: Lead poisoning is normally caused by repeated occupational inhalation of lead. However, lead may also be absorbed through the digestive route. Some alternative medical treatments, such as Ayurvedic medicine, can also contain lead and may result in poisoning. PATIENTS AND METHOD: We collected cases of lead poisoning related to Ayurvedic treatments attended at the Hospital Clinic of Barcelona. RESULTS: Two female patients, aged 45 and 57 years, respectively, who initiated Ayurvedic treatments which involved the ingestion of various medicaments, were included. The first patient presented with anemia and abdominal pain. The lead level was 74µg/dL and free erythrocyte protoporphyrin was 163µg/dL. She was treated with intravenous calcium disodium ethylenediaminetetraacetic acid (CaNa2EDTA) and later with oral dimercaptosuccinic acid (DMSA) with a good evolution. The second patient presented with abdominal pain and a Burton's line. The lead level was 52µg/dL and free erythrocyte protoporphyrin was 262µg/dL. She was treated with oral DMSA and evolved favorably. Lead concentrations in some of the tablets supplied to the patients reached 2,003 and 19,650µg/g of tablet. CONCLUSIONS: Lead poisoning may result from treatments based on Ayurvedic medicine and may reach epidemic proportions. Health control of alternative medicines is necessary.

Long-term effectiveness of bee venom acupuncture and physiotherapy in the treatment of adhesive capsulitis: a one-year follow-up analysis of a previous randomized controlled trial.

OBJECTIVE: An earlier randomized controlled trial (RCT) study showed that bee venom acupuncture (BVA) in combination with physiotherapy can be more effective in functional improvement and pain reduction in patients with adhesive capsulitis (AC). The objective of the current study was to examine the long-term effect of BVA in combination with physiotherapy on AC of the shoulder. DESIGN: Retrospective 1-year follow-up analysis of a previous RCT using a telephone interview method. SETTING: Outpatient joint center at the Gang Dong Kyung Hee University Hospital of Seoul, Republic of Korea. PATIENTS: A total of 192 patients had been enrolled in the previous study, and 124 of these were excluded from the current study. Sixty-eight patients who had been treated with combined BVA and physiotherapy for AC of the shoulder for 2 months were interviewed at approximately 1 year after treatment by telephone. INTERVENTION: Sixty of 68 patients were included in the follow-up analysis. Twenty received BV 1 treatment (1:10,000 concentration BVA plus physiotherapy), 22 received BV 2 treatment (1:30,000 concentration BVA plus physiotherapy), and 18 received control treatment (normal saline injection plus physiotherapy). OUTCOME MEASURES: The primary outcome measure was Shoulder Pain And Disability Index (SPADI) score. Secondary outcome measure was score on verbal rating scale for pain and patient satisfaction. RESULTS: Baseline characteristics of the groups did not significantly differ. SPADI scores at 1 year significantly differed between the BV 1 group and the control group (p=0.043). No significant differences were found in pain verbal rating scores after 1 year. Treatment satisfaction with therapy was also assessed, and the BV 1 and BV 2 groups showed significantly greater satisfaction compared with the control group. CONCLUSIONS: BVA combined with physiotherapy remains clinically effective 1 year after treatment and may help improve long-term quality of life in patients with AC of the shoulder.

Radiological interventions for soft tissue injuries in sport.

Injection therapy has played an integral role in the rehabilitation of sports injuries for many years. The athlete's primary goal is a rapid return to sporting activity. This may be achieved by a combination of either a temporary or permanent reduction in pain, and by a pharmacological or physiological effect that promotes or accelerates a healing response. A wide variety of pharmacological agents are used. However, there is often a lack of good evidence that quantifiable effects can be achieved. There are restrictions on the use of some pharmaceutical agents. This article reviews the various pharmacological agents and bioactive substrates that are available, and discusses the current evidence base of their use in common sports injuries.

Safety and efficacy of methylprednisolone infiltration in anserine syndrome treatment.

OBJECTIVE: The anserine syndrome is a common cause of knee pain. Infiltration with glucocorticoids has been evaluated in studies with low level of evidence and there are no published clinical trials to determine its usefulness. The objective of this study was to determine the efficacy and safety of the infiltration of methylprednisolone in the treatment of Anserin Syndrome. METHODS: We conducted a clinical trial in 58 adult patients with anserin syndrome, which presented intra-articular pathology ruled that reflected pain in the medial aspect of the knee. The WOMAC scale was assessed at baseline and patients were randomized to receive an infiltration of lidocaine plus 40 mg methylprednisolone acetate (group 1) versus xylocaine plus distilled water (group 2). Both groups received 100mg of diclofenac sodium for 10 days. The WOMAC scale was applied at 4 weeks and adverse events were recorded. RESULTS: Equivalence was demonstrated in both groups for demographic variables and initial clinical evaluation. There was no statistical difference in the three domains of assessment of the baseline WOMAC score. The median baseline WOMAC in group 1 was 32 and in group 2 was 25.5 points. At 4 weeks it was 8 and 6.5 points, which corresponded to an improvement of 61.6 and 62.8% respectively. CONCLUSION: The infiltration with methylprednisolone in anserin syndrome is not superior to placebo in patients taking diclofenac measured by the WOMAC scale at 4 weeks. The incidence of adverse events did not show any differences either.

Scapulothoracic bursitis as a significant cause of breast and chest wall pain: underrecognized and undertreated.

OBJECTIVES: Pain is one of the most commonly reported breast complaints. Referred pain from inflammation of the shoulder bursa is often overlooked as a cause of breast pain. The objective of this study is to evaluate the role of shoulder bursitis as a cause of breast/chest pain. METHOD: An IRB-approved retrospective review from July 2005 to September 2009 identified 461 patients presenting with breast/chest pain. Cases identified with a trigger point in the medial aspect of the ipsilateral scapula were treated with a bursitis injection at the point of maximum tenderness. The bursitis injection contains a mixture of local anesthetic and corticosteroid. Presenting complaint, clinical response and associated factors were recorded and treated with descriptive statistics. RESULTS: Average age of the study group was 53.4 ± 12.7 years, and average BMI was 30.4 ± 7.4. One hundred and three patients were diagnosed with shoulder bursitis as the cause of breast pain and received the bursitis injection. Most cases (81/103 or 78.6%) presented with the breast/chest as the site of most significant discomfort, where 8.7% (9/103) had the most severe pain at the shoulder, 3.9% (4/103) at the axilla and 3.9% (4/103) at the medial scapular border. Of the treated patients, 83.5% (86/103) had complete relief of the pain, 12.6% (13/103) had improvement of symptoms with some degree of residual pain, and only 3.9%(4/103) did not respond at all to the treatment. The most commonly associated factor to the diagnosis of bursitis was the history of a previous mastectomy, present in 27.2% (28/103) of the cases. CONCLUSIONS: Shoulder bursitis represents a significant cause of breast/chest pain (22.3% or 103/461) and can be successfully treated with a local injection at site of maximum tenderness in the medial scapular border.

A topically applied quaternary ammonium compound exhibits analgesic effects for orthopedic pain.

OBJECTIVE: To investigate the effectiveness of a topically applied emulsion of an analgesic ammonium solution for the temporary treatment of pain associated with arthritis, tendinitis and bursitis. DESIGN: 100 subjects in a single center, presenting with chronic pain associated with arthritis, tendinitis, or bursitis trialed against placebo in a double-blind cross-over protocol. MAIN OUTCOME MEASURES: Measures of treatment success include reduction in pain, improvement in clinical and/or mechanical evaluations, and evaluation of local and systemic adverse effects. Analysis was conducted at two weeks, after one week's clearance, and again after two weeks. RESULTS: For chronic neuralgia associated with arthritis, tendinitis, and bursitis, the test material had a positive effect at temporary pain reduction. Several subjects also recorded improvements in mechanical evaluations from baseline. Withdrawals due to systemic or local adverse reactions were minimal. CONCLUSION: A topical emulsion of a strong ammonium solution utilizing quaternary ammonium, enhanced with certain penetration enhancers, is effective for temporary relief of pain associated with arthritis, tendinitis, and bursitis.

Compromised wound repair caused by perioperative use of ibuprofen.

Nonsteroidal anti-inflammatory drugs have been shown to inhibit inflammation, an integral part of the wound-healing process. Compromised wound repair has been demonstrated in laboratory animals administered high-dose nonsteroidal anti-inflammatory drugs, a phenomenon we speculate could occur in humans undergoing surgery. We report a dramatic case of impaired wound healing in a patient ingesting high-dose perioperative ibuprofen, a nonsteroidal anti-inflammatory drug.

Comparison of injection techniques for shoulder pain: results of a double blind, randomised study.

Seventy seven patients with soft tissue shoulder lesions including adhesive capsulitis and disorders of the rotator cuff and acromioclavicular joint were admitted to a trial comparing two different methods of corticosteroid injection with local anaesthetic in a randomly allocated double blind study. The method of anatomical injection after diagnosis by the technique of selective tissue tension gave 60% success compared with the method using tender or trigger point localisation, giving 20% success (p less than 0.001).
