We performed a prospective, randomised trial on 106 patients to compare the effects of local corticosteroid injections with physiotherapy as advocated by Cyriax in the treatment of tennis elbow. The main outcome measures were the severity of pain, pain provoked by resisted dorsiflexion of the wrist, and patient satisfaction. At six weeks 22 of 53 patients in the injection group were free from pain compared with only three in the physiotherapy group. In the corticosteroid-treated group 26 patients had no pain on resisted dorsiflexion of the wrist compared with only three in the physiotherapy group. Thirty-five patients who had injections and 14 who had physiotherapy were satisfied with the outcome of treatment at six weeks. At the final assessment there were 18 excellent and 18 good results in the corticosteroid group and one excellent and 12 good results in the physiotherapy group. There was a significant increase in grip strength in both groups but those with injections had a significantly better result. After one year there were no significant differences between the two groups. Half of the patients, however, had received only the initial treatment, 20% had had combined therapy and 30% had had surgery. We conclude that at six weeks, treatment with corticosteroid injections was more effective than Cyriax physiotherapy and we recommend it because of its rapid action, reduction of pain and absence of side-effects

Aims: To assess prospectively the effectiveness and safety of Cortossª, a new synthetic, biocompatible, highly radiopaque composite in the percutaneous augmentation of vertebral compression fractures. Methods: Patients with severe pain (> 50mm VAS) associated to radiographic evidence of osteoporotic or malignant vertebral compression fracture(s). Cortoss was injected with the help of a syringe-catheter system introduced into a 10 to 11-gauge needle under continuous ßuoroscopic control. All leakages and adverse events were to be reported. Assessments were made before vertebroplasty (bv) and after 3 days (3d), 1 week (1w), 1 month (1m), 3 (3m) and 6 months (6m). Results: Fifty-eight interventions were performed in 53 patients. Mean pain scores (mm VAS) decreased from 69 (bv) to 39 (3d), 39 (1w), 31 (1m), 23 (3m), 26 (6m). A mean (range) of 4.3 (1.5–8) mL of Cortoss was injected per vertebral body. Augmented vertebral bodies remained stable over time. Leakage of Cortoss occurred in 76% of interventions. No pulmonary emboli or persistent nerve root or medullary irritation occurred in association to leakage of Cortoss. One patient required local corticosteroid injection for pain associated to soft tissue leakage. The visibility of Cortoss on all imaging techniques was excellent and its use generally considered to be easy. Conclusions: The use of Cortoss for augmentation of vertebral compression fractures appears to be safe and effective and represents a promising biocompatible alternative to PMMA thanks to its radiopacity and ease of use

The aim of the study is to assess the humero radial plica which could be a factor in causing lateral elbow pain. The cause of lateral elbow pain has been an enigma for the orthopaedic surgeons over the years. The synovial fold of the humeroradial joint has been well documented and considered as a meniscus between the articulation. They can also present as symptoms suggesting intra articular loose bodies causing pain in these patients. Our study included 117 consecutive elbow arthroscopies performed by two surgeons for a period of 18 months. All patients were initially treated non-operatively as a ‘tennis elbow’ before undergoing arthroscopy. Conservative treatment included rest, activity modification, physiotherapy including ultrasound bracing, nsaids and local corticosteroid injection. All patients were assessed using the Mayo clinic performance index for elbows both pre and post operatively. Radial head plica was found in 21(18%) out of 117 elbow arthroscopies and was resected using a soft tissue resector. There were 16 (76%) men and 5(24%) women in this affected group and all of whom were young and active with a mean age 38 years. Of the 21 patients 16(76%) had a post operative score of 90 or more (excellent) and 5(24%) had a score 75–89(good). This study addresses the fact that cause of lateral elbow pain can be due to various pathologies in the elbow and in the cases of ‘resistant tennis elbows’ we recommend that the existence of a radial head synovial plica should be considered and if present treatment should be directed at this. Our study demonstrates that by resecting the synovial plical fold, pain will be relieved and these patients regained elbow function. Since this was noted in the young active age group this could reduce the morbidity and the time for rehabilitation required especially for those involved in active sports. A similar series has not been cited in English literature

Introduction: Meralgia paresthetica (MP) is a mononeuropathy of the lateral femoral cutaneous nerve, mainly associated with either injury or pressure to the nerve. Although this entity is well described, most clinical series have employed numerous treatment methods; therefore, the efficacy of individual modalities is unclear. We describe our experience of 79 patients with complaints consistent with MP, treated, by the senior author, over a 13-year period. Materials and Methods: Patients were managed in accordant to a structured protocol:. Initial management consisted of anti inflammatory agents, rest and redaction of aggravating factors. Diagnostic nerve block test was carried out for those who were refractory to the above treatment. All patients who responded to the local anesthetic test were treated with local infiltration of corticosteroids. Surgical intervention was reserved for patients who responded to the lidociane test but were refractory to repeated corticosteroids injections. Patients who failed to respond to the test injection were evaluated by CT-scan of the lumbar spine and by abdominal ultrasound (for female patients only). Follow-up ranged 1–13 years. Results: Twenty-one patients (27%) reported satisfactory results flowing initial management. Local anesthetic yielded rapid relief of symptoms in 50 patients (86%), two additional patients responded to a second nerve block test (where a wider area was infiltrated). In forty-two out of 52 patients (81%) who responded to the nerve block test and received treatment with corticosteroid injections, Long-lasting relief was obtained. Three patients refractory to repeated injections of corticosteroid underwent surgery (neurolysis in one patient and nerve resection in two). CT-scan of the lumbar spine revealed significant spinal stenosis and nerve root compression at the level of L1–3 in 3 out of 6 patients. Conclusion: Idiopathic MP usually improves with nonoperative modalities. Temporary relief of symptoms following LFCN block is a specific diagnostic test, and is a good predictor of success following local corticosteroid injection. Surgery is seldom necessary and should be considered only if intractable pain persists despite such measures

Aims

A local injection may be used as an early option in the treatment of Morton’s neuroma, and can be performed using various medications. The aim of this study was to compare the effects of injections of hyaluronic acid compared with corticosteroid in the treatment of this condition.

Aims

We aimed to establish the short- and long-term efficacy of corticosteroid injection for coccydynia, and to determine if betamethasone or triamcinolone has the best effect.

Aims

The aim of this study was to compare the efficacy of a corticosteroid injection for the treatment of carpal tunnel syndrome (CTS) in patients with and without Raynaud’s phenomenon.

Objectives

Local corticosteroid infiltration is a common practice of treatment for lateral epicondylitis. In recent studies no statistically significant or clinically relevant results in favour of corticosteroid injections were found. The injection of autologous blood has been reported to be effective for both intermediate and long-term outcomes. It is hypothesised that blood contains growth factors, which induce the healing cascade.

Intra-articular punctures and injections are performed routinely on patients with injuries to and chronic diseases of joints, to release an effusion or haemarthrosis, or to inject drugs. The purpose of this study was to investigate the accuracy of placement of the needle during this procedure.

A total of 76 cadaver acromioclavicular joints were injected with a solution containing methyl blue and subsequently dissected to distinguish intra- from peri-articular injection. In order to assess the importance of experience in achieving accurate placement, half of the injections were performed by an inexperienced resident and half by a skilled specialist. The specialist injected a further 20 cadaver acromioclavicular joints with the aid of an image intensifier. The overall frequency of peri-articular injection was much higher than expected at 43% (33 of 76) overall, with 42% (16 of 38) by the specialist and 45% (17 of 38) by the resident. The specialist entered the joint in all 20 cases when using the image intensifier.

Correct positioning of the needle in the joint should be facilitated by fluoroscopy, thereby guaranteeing an intra-articular injection.

Peri-tendinous injection of local anaesthetic, both alone and in combination with corticosteroids, is commonly performed in the treatment of tendinopathies. Previous studies have shown that local anaesthetics and corticosteroids are chondrotoxic, but their effect on tenocytes remains unknown. We compared the effects of lidocaine and ropivacaine, alone or combined with dexamethasone, on the viability of cultured bovine tenocytes. Tenocytes were exposed to ten different conditions: 1) normal saline; 2) 1% lidocaine; 3) 2% lidocaine; 4) 0.2% ropivacaine; 5) 0.5% ropivacaine; 6) dexamethasone (dex); 7) 1% lidocaine+dex; 8) 2% lidocaine+dex; 9) 0.2% ropivacaine+dex; and 10) 0.5% ropivacaine+dex, for 30 minutes. After a 24-hour recovery period, the viability of the tenocytes was quantified using the CellTiter-Glo viability assay and fluorescence-activated cell sorting (FACS) for live/dead cell counts. A 30-minute exposure to lidocaine alone was significantly toxic to the tenocytes in a dose-dependent manner, but a 30-minute exposure to ropivacaine or dexamethasone alone was not significantly toxic.

Dexamethasone potentiated ropivacaine tenocyte toxicity at higher doses of ropivacaine, but did not potentiate lidocaine tenocyte toxicity. As seen in other cell types, lidocaine has a dose-dependent toxicity to tenocytes but ropivacaine is not significantly toxic. Although dexamethasone alone is not toxic, its combination with 0.5% ropivacaine significantly increased its toxicity to tenocytes. These findings might be relevant to clinical practice and warrant further investigation.

The use of ultrasound in the diagnosis and management of disorders of the tendo Achillis is discussed. Some of the pathological processes which occur in Achilles tendinopathy can be identified by ultrasound, which may also be used to direct local treatment.

We have carried out a prospective double-blind randomised controlled trial to compare the efficacy of a single subacromial injection of the non-steroidal anti-inflammatory drug, tenoxicam, with a single injection of methylprednisolone in patients with subacromial impingement. A total of 58 patients were randomly allocated into two groups. Group A received 40 mg of methylprednisolone and group B 20 mg of tenoxicam as a subacromial injection along with lignocaine. The Constant-Murley shoulder score was used as the primary outcome measure and the Disability of Arm, Shoulder and Hand (DASH) and the Oxford Shoulder Score (OSS) as secondary measures. Six weeks after injection the improvement in the Constant-Murley score was significantly greater in the methylprednisolone group (p = 0.003) than in the tenoxicam group. The improvement in the DASH score was greater in the steroid group and the difference was statistically significant and consistent two (p < 0.01), four (p < 0.01) and six weeks (p < 0.020) after the injection. The improvement in the OSS was consistently greater in the steroid group than in the tenoxicam group. Although the difference was statistically significant at two (p < 0.001) and four (p = 0.003) weeks after the injection, it was not at six weeks (p = 0.055). Subacromial injection of tenoxicam does not offer an equivalent outcome to subacromial injection of corticosteroid at six weeks. Corticosteroid is significantly better than tenoxicam for improving shoulder function in tendonitis of the rotator cuff after six weeks.
