Objectives. Triamcinolone acetonide (TA) is widely used for the treatment of rotator cuff injury because of its anti-inflammatory properties. However, TA can also produce deleterious effects such as tendon degeneration or rupture. These harmful effects could be prevented by the addition of platelet-rich plasma (PRP), however, the anti-inflammatory and anti-degenerative effects of the combined use of TA and PRP have not yet been made clear. The objective of this study was to determine how the combination of TA and PRP might influence the inflammation and degeneration of the rotator cuff by examining rotator cuff-derived cells induced by interleukin (IL)-1ß. Methods. Rotator cuff-derived cells were seeded under inflammatory stimulation conditions (with serum-free medium with 1 ng/ml IL-1ß for three hours), and then cultured in different media: serum-free (control group), serum-free + TA (0.1mg/ml) (TA group), serum-free + 10% PRP (PRP group), and serum-free + TA (0.1mg/ml) + 10% PRP (TA+PRP group). Cell morphology, cell viability, and expression of inflammatory and degenerative mediators were assessed. Results. Exposure to TA significantly decreased cell viability and changed the cell morphology; these effects were prevented by the simultaneous administration of PRP. Compared with the control group, expression levels of inflammatory genes and reactive oxygen species production were reduced in the TA, PRP, and TA+PRP groups. PRP significantly decreased the expression levels of degenerative marker genes. Conclusions. The combination of TA plus PRP exerts anti-inflammatory and anti-degenerative effects on rotator cuff-derived cells stimulated by IL-1ß. This combination has the potential to relieve the symptoms of rotator cuff injury. Cite this article: T. Muto, T. Kokubu, Y. Mifune, A. Inui, R. Sakata, Y. Harada, F. Takase, M. Kurosaka.

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. Methods. During 2009 to 2016, we treated 277 patients with chronic coccydynia with either one 6 mg betamethasone or one 20 mg triamcinolone cortisone injection. A susequent injection was given to 62 (26%) of the patients. All were reviewed three to four months after injection, and 241 replied to a questionnaire a mean of 36 months (12 to 88) after the last injection. No pain at the early review was considered early success. When the patient had not been subsequently operated on, and indicated on the questionnaire that they were either well or much better, it was considered a long-term success. Results. At the three- to four-month review, 22 (9%) reported that they had no pain. The long-term success of one injection was 15% and rose to 29% after a second injection. Logistic regression tests showed that both early success (odds ratio (OR) 5.5, 95% confidence interval (CI) 2.1 to 14.4; p = 0.001) and late success (OR 3.7, 95% CI 1.7 to 8.3; p = 0.001) was greater with triamcinolone than with betamethasone. Late success was greater for patients with symptoms for less than 12 months (OR 3.0, 95% CI 1.4 to 6.7; p = 0.006). We saw no complications of the injections. Conclusion. We conclude that the effect of corticosteroid injection for coccygodynia is moderate, possibly because we used modest doses of the drugs. Even so, they seem worthwhile as they are easily and quickly performed, and complications are rare. If the choice is between injections of betamethasone or triamcinolone, the latter should be selected. Cite this article: Bone Joint Open 2020;1-11:709–714

Objectives. To investigate the appropriate dose and interval for the administration of triamcinolone acetonide (TA) in treating tendinopathy to avoid adverse effects such as tendon degeneration and rupture. Methods. Human rotator cuff-derived cells were cultured using three media: regular medium (control), regular medium with 0.1 mg/mL of TA (low TA group), and with 1.0 mg/mL of TA (high TA group). The cell morphology, apoptosis, and viability were assessed at designated time points. Results. In the low TA group, the cells became flattened and polygonal at seven days then returned to normal at 21 days. The cell apoptosis ratio and messenger ribonucleic acid expression of caspase-3, 7, 8, and 9 increased, and viability was reduced in the low and high groups at seven days. In the low TA group, apoptosis and viability returned to normal at 21 days, however, in the high TA group, the cell morphology, apoptosis ratio, caspase-3, 7, 8, and 9 and viability did not return by day 21. Re-administration was performed in the low TA group at 7-, 14-, and 21-day intervals, and cell viability did not return to the control level at the 7- and 14-day intervals. Conclusion. A 0.1 mg/mL dose of TA temporarily decreased cell viability and increased cell apoptosis, which was recovered at 21 days, however, 1 mg/mL of TA caused irreversible damage to cell morphology and viability. An interval > three weeks was needed to safely re-administer TA. These findings may help determine the appropriate dose and interval for TA injection therapy.

Objectives. Intra-articular injections of local anaesthetics (LA), glucocorticoids (GC), or hyaluronic acid (HA) are used to treat osteoarthritis (OA). Contrast agents (CA) are needed to prove successful intra-articular injection or aspiration, or to visualize articular structures dynamically during fluoroscopy. Tranexamic acid (TA) is used to control haemostasis and prevent excessive intra-articular bleeding. Despite their common usage, little is known about the cytotoxicity of common drugs injected into joints. Thus, the aim of our study was to investigate the effects of LA, GC, HA, CA, and TA on the viability of primary human chondrocytes and tenocytes in vitro. Methods. Human chondrocytes and tenocytes were cultured in a medium with three different drug dilutions (1:2; 1:10; 1:100). The following drugs were used to investigate cytotoxicity: lidocaine hydrochloride 1%; bupivacaine 0.5%; triamcinolone acetonide; dexamethasone 21-palmitate; TA; iodine contrast media; HA; and distilled water. Normal saline served as a control. After an incubation period of 24 hours, cell numbers and morphology were assessed. Results. Using LA or GC, especially triamcinolone acetonide, a dilution of 1:100 resulted in only a moderate reduction of viability, while a dilution of 1:10 showed significantly fewer cell counts. TA and CA reduced viability significantly at a dilution of 1:2. Higher dilutions did not affect viability. Notably, HA showed no effects of cytotoxicity in all drug dilutions. Conclusion. The toxicity of common intra-articular injectable drugs, assessed by cell viability, is mainly dependent on the dilution of the drug being tested. LA are particularly toxic, whereas HA did not affect cell viability. Cite this article: P. Busse, C. Vater, M. Stiehler, J. Nowotny, P. Kasten, H. Bretschneider, S. B. Goodman, M. Gelinsky, S.

Background. Infiltration is considered the first treatment option for symptomatic Morton's neuroma and can be performed with various medications. The aim of this study was to compare the effects of hyaluronic acid infiltration versus corticosteroid injection in the treatment of Morton's neuroma. Methods. A randomised clinical trial was conducted with 46 patients (50 feet) diagnosed with Morton's neuroma. After randomisation, the control group (CG) received three injections (one per week) of triamcinolone (Triancil®) guided by ultrasound, while the study group (SG) received three applications of hyaluronic acid (Osteonil Plus®). Patients were followed up for six months after the intervention. The primary outcome measure used was the Visual Pain Analog Scale (VAS). Secondary endpoints included patient-reported outcome measures using the American Orthopaedic Foot & Ankle Society (AOFAS) score and complications. Results. Both groups showed significant improvement in VAS and AOFAS scores (p < 0.001). The CG showed greater improvement than the SG in the VAS (p < 0.05) and AOFAS (p < 0.001) variables. Four patients in the CG experienced skin hypochromia at the injection site, while there were no complications in the SG. Conclusion. Ultrasound-guided hyaluronic acid infiltration in Morton's Neuroma proved to be safe, showing improvement in pain and function after six months of follow-up, without major complications, but with a significantly lower improvement when compared to corticosteroid injection. Taking into account cost implications and the potential for longer lasting improvement from viscosupplementation further medium- and long-term studies are needed


In osteoarthritis, chondrocytes acquire a hypertrophic phenotype that contributes to matrix degradation. Inflammation is proposed as trigger for the shift to a hypertrophic phenotype. Using in vitro culture of human chondrocytes and cartilage explants we could not find evidence for a role of inflammatory signalling activation. We found, however, that tissue repair macrophages may contribute to the onset of hypertrophy (doi: 10.1177/19476035211021907) Intra-articularly injected triamcinolone acetonide to inhibit inflammation in a murine model of collagenase-induced osteoarthritis, increased synovial macrophage numbers and osteophytosis, confirming the role of macrophages in chondrocyte hypertrophy occurring in osteophyte formation (doi: 10.1111/bph.15780). In search of targets to inhibit chondrocyte hypertrophy, we combined existing microarray data of different cartilage layers of murine growth plate and murine articular cartilage after induction of collagenase-induced osteoarthritis. We identified common differentially expressed genes and selected those known to be associated to inflammation. This revealed EPHA2, a tyrosine kinase receptor, as a new target. Using in silico, in vitro and in vivo models we demonstrated that inhibition of EPHA2 might be a promising treatment for osteoarthritis. Recently, single cell RNA-seq. has revealed detailed information about different populations of chondrocytes in articular cartilage during osteoarthritis. We re-analysed a published scRNA-seq data set of healthy and osteoarthritic cartilage to obtain the differentially expressed genes in the population of hypertrophic chondrocytes compared to the other chondrocytes, applied pathway analyses and then used drug databases to search for upstream inhibitors of these pathways. This drug repurposing approach led to the selection of 6 drugs that were screened and tested using several in vitro models with human chondrocytes and cartilage explants. In this lecture I will present this sequence of studies to highlight different approaches and models that can be used in the quest for a disease modifying drug for osteoarthritis

This was a double-blind randomised controlled study. The objective of this study was to determine the cause of post-injection pain after peri-articular steroid injection. Approval for this study was granted by the hospital’s Ethics Committee. Selection criteria included all patients undergoing a peri-articular injection under the care of the senior author. Patients who elected to be in this study gave their consent following a detailed explanation of the study and provision of a patient information leaflet. The enrolled patients were randomised into one of two groups. Group A received a standard triamcinolone acetonide injection mixed with bupivicaine. Group B patients received triamcinolone acetonide without the preservative part of the drug and bupivicaine. Both the patient and the surgeon were unaware which group the patient was selected to be in. Patients’ scores were recorded using visual analogue scales and pain severity scores prior to injection and 4 days following injection. Inflammatory signs were also recorded at 4 days post-procedure. A total of 52 patients were enrolled. Pain scores reduced by 46% in group A and 43% in group B. Inflammatory signs occurred in 26% less cases when group B was compared with group A, however this was not statistically significant

Summary. Corticosteroids (CS) are commonly administered by intra-articular injection to control the symptoms of osteoarthritis; however, CSs also suppress articular chondrocyte matrix synthesis. Both triamcinolone and methylprednisolone acetate significantly suppressed BMPs −2 and −7, and TGF-b1 expression, suggesting a mechanism by which CSs suppress articular chondrocyte matrix synthesis and cartilage homeostasis. Introduction. Osteoarthritis (OA) is a common and debilitating disease that affects approximately 30% of the US population and is also a major clinical problem in companion animals. There are many drugs available to manage the symptoms of OA. Of these, intra-articular corticosteroid (CS) administration is a common and very effective anti-arthritic therapy, and is frequently administered to equine athletes. CSs exert their potent anti-inflammatory effects by blocking phospholipase A and reducing inflammatory mediator production; however, CSs also suppress matrix-biosynthetic activity of articular chondrocytes. This activity, along with ther increased joint use that symptomatic relief allows, has been linked to ‘steroid arthropathy’; a progression of arthritis driven by compromised chondrocyte homeostatic capacity. Several lines of experimental and clinical evidence emphasise the importance of TGF-b and BMP autocrine/paracrine activity in maintaining the homeostatic status of articular chondrocytes (reviewed in Oshin and Stewart 2007). This study was carried out to address the following objectives: 1) To assess the effects of CS on expression of chondro-protective TGF-β and BMP ligands in equine articular chondrocytes, and 2) To determine if exogenous BMP ligand administration can mitigate the suppressive effects of CSs on articular chondrocyte synthesis of collagen type II (Coll II) and glycosaminoglycans (sGAG). Methods. Articular cartilage was collected from clinically normal joints of adult horses, euthanased for reasons other than musculoskeletal disease. Articular chondrocytes were isolated by collagenase digestion and cultured as aggregates in serum-free medium under non-adherent conditions (Stewart et al 2000). Triamcinolone acetate (TA) or methylprednisolone acetate (MPA) was added to the articular chondrocyte cultures at 10. −10. M, 10. −7. M, and 10. −5. M; comparable to in vivo exposure concentrations. Effects on Coll II, aggrecan/sGAG, BMP and TGF-b ligand expression were assessed by QPCR, Coll II ELISAs and DMMB assays. In a separate series of experiments, exogenous BMP-2 was administered to chondrocyte cultures exposed to CS supplementation, to determine whether BMP can prevent or mitigate CS-mediated suppression of matrix synthesis. Results. BMP-2 and BMP-7 mRNA levels were significantly down-regulated by both CS treatments. In contrast, expression of BMPs-4 and 6 was not affected at any of the CS doses tested. TGF-b1 mRNA levels were significantly suppressed by both CSs at all doses tested. Somewhat surprisingly, TGF-b2 expression was increased by CS administration, though not significantly, while TGF-b3 expression was not affected. Exogenous BMP-2 administration (1–100 ng/ml) increased Coll II expression in the control groups but did not prevent the suppression of Coll II or sGAG synthesis in CS-treated chondrocytes. Discussion/Conclusions. Both TA and MPA down-regulated BMP-2, BMP-7 and TGF-b1 mRNA expression in articular chondrocytes. These CS-mediated effects appear to be gene-specific, since BMPs-4 and 6, and TGF-bs 2 and 3 were not similarly affected. Although exogenous BMP-2 administration increased Coll II production under control conditions, this did not effectively prevent CS-mediated suppressive effects on cartilage matrix synthesis. This suggests that other elements of the articular chondrocyte BMP and/or TGF-b signaling pathways are also affected by CS administration

Joint injuries often result in inflammation and cartilage defects. When inflamed, the synovium secretes factors that prevent successful cartilage repair by inhibiting chondrogenic differentiation of progenitor cells. In particular the pro-inflammatory macrophages in the synovium are indicated to contribute to this anti-chondrogenic effect. Thus, we aimed to counteract the anti-chondrogenic effect of inflamed synovium by modulating synovial inflammation and its macrophages. Synovium tissue obtained from osteoarthritic patients undergoing a total knee replacement was cut into explants and cultured for 72 hours +/− 1 µM of the anti-inflammatory drug triamcinolone acetonide (TAA) (Sigma Aldrich). TAA significantly decreased gene expression of TNFA, IL1β and IL6, and increased expression of CCL18, IL1RA in synovial explants (all with p < 0.001). On the other hand, TAA significantly decreased the percentages of pro-inflammatory CD14+/CD80+ and CD14+/CD86+ macrophages in the synovium (both p < 0.001) as assessed by flow cytometry analyses. The percentages of anti-inflammatory CD14+/CD163+ macrophages, is significantly increased (p < 0.001) in TAA treated synovium. Conditioned medium (CM) from synovium explants downregulated the gene expression of cartilage matrix components collagen type-2 and aggrecan expression in chondrogenic MSCs. This chondrogenesis inhibiting effect was reduced by treating synovium with TAA during the production of the CM. Our findings indicate that reducing synovial inflammation might improve the joint environment for better cartilage repair, possibly by modulation of macrophage phenotypes

Introduction. Adhesive capsulitis is a common condition causing painful limitation of shoulder movements. Hydrodistension is one of the techniques, is well recognised and has shown good outcomes. However, the results of hydro distension release in secondary adhesive capsulitis are not clear. Patients and Methods. This is a retrospective study on patients undergoing hydro distension release. Patients who had any surgical intervention were classed as secondary whilst the rest were included in the primary group. The hydro distension is a standard technique where in the senior author locates the gleno humeral joint using radio opaque dye, followed by injection of 20 mls 0.5% L-bupivacaine and 80 mg of Triamcinolone, this is followed by use of 60 mls saline to perform the hydro distension. Results. We included 86 shoulders in 80 patients who underwent the procedure. There were 46 females and 34 males, with average age of 51.07 years (range 35 – 75). Left side was involved in 42 shoulders and right in 44. 25 patients showed associated risk factors of which 17 patients had diabetes, 12 had hypercholesterolemia and 5 had underactive thyroid. 65 of the shoulders were in the primary group whilst 21 in the secondary group. In the secondary group the procedures included 8 arthroscopic subacromial decompression with ACJ excision, 7 had rotator cuff repairs, 4 had biceps labral procedure and 2 ORIF clavicle. 3/21 patients required further intervention in secondary group, whilst 10/65 in the primary group required further intervention. Patients who have history of inflammatory arthritides were found to have higher incidence of revision surgery and poorer outcomes. 85% patients in both groups had improvement in their function and range of movements and were happy with the outcome. Conclusion. Hydrodistension provides safe and predictive results in both primary and secondary adhesive capsulitis and should be considered as an option before any invasive procedure

Aims

Steroid injections are used for subacromial pain syndrome and can be administered via the anterolateral or posterior approach to the subacromial space. It is not currently known which approach is superior in terms of improving clinical symptoms and function. This is the protocol for a randomized controlled trial (RCT) to compare the clinical effectiveness of a steroid injection given via the anterolateral or the posterior approach to the subacromial space.

Methods

The Subacromial Approach Injection Trial (SAInT) study is a single-centre, parallel, two-arm RCT. Participants will be allocated on a 1:1 basis to a subacromial steroid injection via either the anterolateral or the posterior approach to the subacromial space. Participants in both trial arms will then receive physiotherapy as standard of care for subacromial pain syndrome. The primary analysis will compare the change in Oxford Shoulder Score (OSS) at three months after injection. Secondary outcomes include the change in OSS at six and 12 months, as well as the Pain Numeric Rating Scale (0 = no pain, 10 = worst pain), Disabilities of Arm, Shoulder and Hand questionnaire (DASH), and 36-Item Short-Form Health Survey (SF-36) (RAND) at three months, six months, and one year after injection. Assessment of pain experienced during the injection will also be determined. A minimum of 86 patients will be recruited to obtain an 80% power to detect a minimally important difference of six points on the OSS change between the groups at three months after injection.

Local infiltration analgesia (LIA) is promoted as an effective treatment modality for pain control after total knee arthroplasty (TKA) (1). A mixture of drugs is used to provide a multimodal analgesic effect. Previous studies reported that the use of these drugs is safe. After we carefully implemented a LIA study protocol in our practice, concerns raised about patient safety with probably higher infection rates. This forced us to perform an interim analysis after the first 58 cases. 58 patients underwent a unilateral TKA with a standardised LIA protocol (2), which consisted of a mixture of ropivacaine, epinephrine, and triamcinolone acetonide. Complications, knee function and patient satisfaction scores were prospectively recorded during regular outpatient control. Four patients (6.9%) presented with signs of periprosthetic joint infection (PJI) within two months after surgery. Baseline characteristics were similar between the infected and non infected group. All infections were treated with debridement and retention, and antimicrobial treatment was started. One patient who suffered an infection died during followup. At two years followup all implants could be retained. Knee function and KSS score were acceptable for the patients who suffered PJI. There is no consensus on the combination of drugs used for LIA. The application of corticosteroids in LIA is reported to be safe (3), but arguable results about the injection of local corticosteroids around knee arthroplasty surgery in the past have raised suspicion in literature (4). Combined with our unacceptable high rate of PJI, we believe that the current body of evidence, with small heterogeneous series, does not support the safe use of corticosteroids in LIA

Aims

Dupuytren’s contracture is characterized by increased fibrosis of the palmar aponeurosis, with eventual replacement of the surrounding fatty tissue with palmar fascial fibromatosis. We hypothesized that adipocytokines produced by adipose tissue in contact with the palmar aponeurosis might promote fibrosis of the palmar aponeurosis.

Methods

We compared the expression of the adipocytokines adiponectin and leptin in the adipose tissue surrounding the palmar aponeurosis of male patients with Dupuytren’s contracture, and of male patients with carpal tunnel syndrome (CTS) as the control group. We also examined the effects of adiponectin on fibrosis-related genes and proteins expressed by fibroblasts in the palmar aponeurosis of patients with Dupuytren’s contracture.

Introduction. Total knee arthroplasty is a painful operation. Peri-articular local anesthetic injections reduce post-operative pain and assist recovery. It is inconclusive whether intra-operative injections of peri-articular corticosteroids are of benefit. Clinical Question: In patients with osteoarthritis who are undergoing TKA, does the addition of high or low dose corticosteroid to peri-articular injections of local anesthetic and adrenaline improve post-operative pain and range of motion?. Methods. A prospective, randomized, double-blinded study was undertaken to assess the efficacy of adding peri-articular corticosteroids to intra-operative, peri-articular high volume local anaesthetic in post-operative pain management following TKA. 127 patients were randomised into three groups receiving local anaesthetic alone (control) or either low dose (40 mg) or high dose (80 mg) peri-articular corticosteroid plus local anaesthetic. Primary outcomes included ROM and visual analog pain scores (VAS). Pain was defined as the worst pain lasting for more than 20 minutes, measured at both rest (RVAS) and during activity (AVAS). Results. There were no significant between-group differences for age, body mass index (BMI), pre-operative ROM or pre-operative pain scores. There were no statistically significant differences in primary or secondary outcomes between the groups. This was the case at all time points. Analysis of non-significant trends demonstrated a 17.7% reduction in RVAS between the control group and high dose steroid group at 12-weeks. This trend was also apparent at 2 and 6 weeks. There was no trend towards decreased total morphine equivalents (or any other secondary outcome) between the control and high dose groups. Discussion. Corticosteroids have been postulated to facilitate post-operative ROM and reduce pain after TKA. However we were unable to show any significant clinical effect of peri-articular triamcinolone acetate at two different dosages. While it appears that corticosteroids are safe to administer in a select patient population, the results of this paper do not suggest a benefit in TKA

Aim: This study aims to quantify pain relief and quality-of-life benefit from a diagnostic SIJ injection. Methods: 50 consecutive patients were retrospectively recruited with unilateral low back pain, pain mapping compatible with a sacroiliac origin, tenderness over the SIJ, and no obvious source of pain in the lumbar spine. These were selected for a diagnostic SIJ injection. A structured questionnaire was completed both pre- and post-injection. Median patient age was 63. All patients were injected under fluoroscopic imaging with Triamcinolone 40mgs and 3mls Ropivacaine hydrochloride. Results: Onset of lower back pain symptoms ranged from 1962 to 2007. 38 patients (76%) had some form of previous non-operative treatment. No patients had previous injection or surgery. 8 patients (16%) were smokers. 17 patients (34%) had a desk based job, 22 patients (44%) had a manual job, 7 patients (14%) had heavy manual jobs. 18 patients (36%) had sustained previous back injury. A visual assessment score was carried out for low back pain and pain in both legs, both pre- and post-injection. Overall, 16 patients (32%) reported no change in their symptoms, 7 (14%) reported worsening, but in 27 (54%) improvement was recorded. When considering the Oswestry Disability Index score, 18% reported no symptom change, 24% worsened and 58% improved. Conclusion: History and physical examination can enter SIJ syndrome into the differential diagnosis, but cannot make a definitive diagnosis. Fluoroscopically guided diagnostic SIJ injection is the gold standard test for making the diagnosis whilst also conferring substantial pain relieve and quality-of-life benefit. Conflicts of Interest: None. Source of Funding: None

Introduction: Intra-articular steroid injection has been widely used for relief of pain in osteoarthritis. Recent studies show an increasing rate of infection in these patients following hip arthroplasty. We have reviewed our cohort of patients to see if they are susceptible to higher infection rate. Methods: We reviewed a cohort of 167 consecutive hips that had at least one injection with a 40mg triamcinolone acetonide and 4ml 0.5% bupivacaine mixture to relieve the symptoms of hip osteoarthritis or to clarify a diagnosis of hip arthritis between January 1997 and November 2004 were reviewed. A total of 37 hips (36 patients) that subsequently proceeded to have a total hip arthroplasty were selected as our study group. There was a minimum of a one-year follow up. Results: The rate of infection in our initial cohort of patients following a hip injection was 0.60% (1 hip) which resulted in repeated washouts and a subsequent total hip arthroplasty with a good outcome. On review of the 37 hips, one was revised due to a deep infection secondary to staphylococcus epidermidis. Four were revised for continued instability and pain with no evidence of infection either prior to or during revision. When deep infection is taken as an endpoint, cumulative survival at 7.5 years is 0.968 (95% confidence interval of 1 to 0.905). The total survivorship of this cohort if all revisions are included is 0.852 at 7.5 years (95% confidence interval of 0.730 to 0.974). The revision rate due to a deep infection in our study is 2.7%. Discussion: We conclude that patients who have a total hip arthroplasty after a hip injection do not have an adversely high rate of deep infection

Intra-articular steroid injection has been widely used for relief of pain in Osteoarthritis. Recent studies show an increasing rate of infection in these patients following hip arthroplasty. We have reviewed our cohort of patients to see if they are susceptible to higher infection rate. We reviewed a cohort of 167 consecutive hips that had at least one injection with a 40mg triamcinolone acetonide and 4ml 0.5% bupivacaine mixture to relieve the symptoms of hip osteoarthritis or to clarify a diagnosis of hip arthritis between January 1997 and Novem-ber 2004 were reviewed. A total of 37 hips (36 patients) that subsequently proceeded to have a total hip arthroplasty were selected as our study group. There was a minimum of a one-year follow up. The rate of infection in our initial cohort of patients following a hip injection was 0.60% (1 hip) which resulted in repeated washouts and a subsequent total hip arthroplasty with a good outcome. On review of the 37 hips, one was revised due to a deep infection secondary to staphylococcus epidermidis. Four were revised for continued instability and pain with no evidence of infection either prior to or during revision. When deep infection is taken as an endpoint, cumulative survival at 7.5 years is 0.968 (95% confidence interval of 1 to 0.905). The total survivorship of this cohort if all revisions are included is 0.852 at 7.5 years (95% confidence interval of 0.730 to 0.974). The revision rate due to a deep infection in our study is 2.7%. We conclude that patients who have a total hip arthroplasty after a hip injection do not have an adversely high rate of deep infection

We describe results of a new ‘two needle technique’ of selective nerve root blocks done through posterior triangle of neck in the management of cervical radiculopathy with 2 year results. Methods: Patients presenting with cervical radiculopathy were evaluated clinically and radiologically and were initially managed with supervised physiotherapy, analgesics and rest. Selective cervical nerve root block was offered to the patients, who did not respond to conservative management. The procedure was performed as a day case, under local anesthesia, with image intensifier guidance, using ‘two needle technique’. A thinner needle is rail-roaded through the lumen of large diameter guide needle to reach the target nerve root foramen and a mixture of Bupivacaine and Triamcinolone acetonide is injected. The outcome was measured using visual analogue score (VAS) and neck disability index (NDI) done on the day of the procedure and compared to the scores at 3 months and 1 year after the procedure. Results: Outcome in 30 patients who underwent this procedure over three years’ period is presented. Average Visual Analogue Score was 7.36 (range 6 – 10) before the intervention, which improved to 2.27 (range 0 – 7) at 3 months and 1.9 (range 0 – 4) at 1 year. The average Neck Disability Index score prior to intervention was 66.87 (range 44 to 82), which improved to 31.67 (range 18 – 66) at 3 months and 30.44 (range 20 – 48) at 1 year. There were no major complications noted. We conclude that selective cervical nerve root block using ‘two-needle technique’ is safe and reproducible. The therapeutic effect achieved is long lasting, making this procedure a good alternative to surgical management in patients with cervical radiculopathy who do not respond to conservative management

Objective:. To study whether intra-articular triamcinolone hexacetonide (iaTH) for the treatment of coxitis in patients with juvenile rheumatoid arthritis (JRA) causes femoral head necroses (FHN). Methods:. Fifty consecutive patients with JRA and coxitis were studied prospectively. Forty-eight children received iaTH in sixty-seven arthritic hips. The remaining two children exhibited three cases of femoral head necrosis at the initial assessment and were only followed; both were receiving long-term systemic steroids (LTSS). After a minimum of two years, the study was concluded with a final evaluation including MRI. Results:. In thirty-nine of sixty-seven hip joints (58%), remission of the coxitis for a period of two years was obtained through a single administration of iaTH, another twelve hip joints went into remission after repeated TH injections (total remission rate = 76%). We observed two cases of femoral head necrosis (FHN) following iaTH. Both children were receiving LTSS. During the period between onset of JRA and screening assessment for this study, the children exhibited 2. 4 cases of FHN per 100 patient years vs. 1. 5 cases of FHN per 100 patient years between iaTH treatment and final follow-up. All five observed cases of FHN occurred among the twenty children who received LTSS, whereas no necrosis occurred in the thirty children who did not receive systemic corticosteroids (PÊ=Ê0. 009 Fisher’s Exact Test). Conclusions:. IaTH for juvenile rheumatoid coxitis was an effective treatment which did not increase the rate of FHN. Systemic steroids, however, (or their co-variable, severity of JRA) do increase the risk of FHN in JRA
