Perioperative glucocorticoids have been used as a successful non-opioid analgesic adjunct for various orthopaedic procedures. Here we describe an ongoing randomized control trial assessing the efficacy of a post-operative methylprednisolone taper course on immediate post-operative pain and function following surgical distal radius fixation. We hypothesize that a post-operative methylprednisolone taper course following distal radius fracture fixation will lead to improved patient pain and function. This study is a randomized control trial (NCT03661645) of a group of patients treated surgically for distal radius fractures. Patients were randomly assigned at the time of surgery to receive intraoperative dexamethasone only or intraoperative dexamethasone followed by a 6-day oral methylprednisolone (Medrol) taper course. All patients received the same standardized perioperative pain management protocol. A pain journal was used to record visual analog pain scores (VAS-pain), VAS-nausea, and number of opioid tablets consumed during the first 7 post-operative days (POD). Patients were seen at 2-weeks, 6-weeks, and 12-weeks post-operatively for clinical evaluation and collection of patient reported outcomes (Disabilities of the Arm, Shoulder and Hand Score [qDASH]). Differences in categorical variables were assessed with χ2 or Fischer's exact tests. T-tests or Mann-Whitney-U tests were used to compare continuous data. Forty-three patients were enrolled from October 2018 to October 2019. 20 patients have been assigned to the control group and 23 patients have been assigned to the treatment group. There were no differences in age (p=0.7259), Body Mass Index (p=0.361), race (p=0.5605), smoking status (p=0.0844), or pre-operative narcotic use (p=0.2276) between cohorts. 83.7% (n=36) of patients were female and the median age was 56.9 years. No differences were seen in pre-operative qDASH (p=0.2359) or pre-operative PRWE (p=0.2329) between groups. In the 7 days following surgery, patients in the control group took an average of 16.3 (±12.02) opioid tablets, while those in the treatment group took an average of 8.71 (±7.61) tablets (p=0.0270). We see that significant difference in Opioid consumption is formed at postoperative day two between the two groups with patients in the control group taking. Patient pain scores decreased uniformly in both groups to post-operative day 7. Patient pain was not statistically from POD0 to POD2 (p=0.0662 to 0.2923). However, from POD4 to POD7 patients receiving the methylprednisolone taper course reported decreased pain (p=0.0021 to 0.0497). There was no difference in qDASH score improvement at 6 or 12 weeks. Additionally, no differences were seen for wrist motion improvement at 6 or 12 weeks. A methylprednisolone taper course shows promise in reducing acute pain in the immediate post-operative period following distal radius fixation. Furthermore, although no statistically significant reductions in post-operative opioid utilization were noted, current trends may become statistically significant as the study continues. No improvements were seen in wrist motion or qDASH and continued enrollment of patients in this clinical trial will further elucidate the role of methylprednisolone for these outcomes

Aims

Aneurysmal bone cysts (ABCs) are locally aggressive lesions typically found in the long bones of children and adolescents. A variety of management strategies have been reported to be effective in the treatment of these lesions. The purpose of this review was to assess the effectiveness of current strategies for the management of primary ABCs of the long bones.

Aims

Optimal exposure through the direct anterior approach (DAA) for total hip arthroplasty (THA) conducted on a regular operating theatre table is achieved with a standardized capsular releasing sequence in which the anterior capsule can be preserved or resected. We hypothesized that clinical outcomes and implant positioning would not be different in case a capsular sparing (CS) technique would be compared to capsular resection (CR).

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

Intravenous dexamethasone has been shown to reduce immediate postoperative pain after total hip arthroplasty (THA), though the effects are short-lived. We aimed to assess whether two equivalent perioperative split doses were more effective than a single preoperative dose.

Aims

Although periarticular injection plays an important role in multimodal pain management following total hip arthroplasty (THA), there is no consensus on the optimal composition of the injection. In particular, it is not clear whether the addition of a corticosteroid improves the pain relief achieved nor whether it is associated with more complications than are observed without corticosteroid. The aim of this study was to quantify the safety and effectiveness of cortocosteroid use in periarticular injection during THA.

Introduction. In early stage osteonecrosis of the femoral head (ONFH), core decompression (CD) is often performed; however, approximately 30% of CD cases progress to femoral head collapse. Bone healing can be augmented by preconditioning MSCs (pMSCs) with inflammatory cytokines. Another immunomodulatory approach is the timely resolution of inflammation using cytokines such as IL-4. We investigated the efficacy of pMSC and genetically modified MSCs that over-express IL-4 (IL4-MSCs) on steroid-associated ONFH in rabbits. Methods. Thirty-six male skeletally mature NZW rabbits received methylprednisolone acetate (20mg/kg) IM once 4 weeks before surgery. There were 6 groups:. CD alone – a 3 mm drill hole. + injection into the CD of:. hydrogel (HG) - 200 μl of hydrogel carrier. MSCs–1 million rabbit MSCs. pMSC - LPS (20 μg/ml) + TNFα (20 ng/ml) preconditioned MSCs. IL4-MSCs – rabbit IL-4 over-expressing MSCs. IL4-pMSCs – preconditioned IL-4 over-expressing MSCs. Eight weeks after surgery, femurs were harvested, and evaluated by microCT, biomechanical, and histological analyses. Results. Bone mineral density (BMD) and bone volume fraction (BVF) increased in the pMSC group compared to the CD and MSC groups . outside. of the CD area (p < 0.05, Fig.1). Similarly, the IL4-pMSC group was increased compared to the CD group (p < 0.05). The percentage of empty lacunae in the IL4-MSC group was significantly less than other groups . outside. the CD area (p < 0.05, Fig.2); however, IL4-MSC group had less trabecular bone formation . inside. the CD. The mechanical tests demonstrated no differences. Discussion. This rabbit steroid-associated ONFH model demonstrated that pMSC increased new bone formation after CD; IL4-MSCs that continuously secreted IL-4 decreased the number of empty lacunae . Immunomodulation of bone healing has the potential to improve bone healing after CD for early stage ONFH; these interventions must be applied in a temporally sensitive fashion.

Knee osteoarthritis is a common, debilitating condition. Intra articular corticosteroid injections are a commonly used non-operative treatment strategy. Intra articular hip injection with Ketorolac (an NSAID) has proven to be as efficacious as corticosteroids. No prior study compares the efficacy of Ketorolac relative to corticosteroids for relief of discomfort in knee osteoarthritis. The study design was a single centre double blinded RCT. Severity of osteoarthritic changes were graded on plain film weightbearing radiographs using the Kellgren and Lawrence system. Injection was with either 30mg Ketorolac or 40mg Methylprednisolone, given by intra-articular injection, in a syringe with 5mls 0.5% Marcaine. Pre-injection clinical outcomes were assessed using the Numerical Pain Score (NPS), WOMAC, and Oxford knee scores. Patients' NPS scores were assessed at Day 1 and Day 14 post-injection. An assessment of all clinical outcomes took place in clinic at six weeks. There were 72 participants (83 knees) in the study. No patients were lost to follow-up. Mean age was 62.66 years (Range 29–85). 42 knees received a corticosteroid injection, 41 a NSAID injection. Mean Kellgren and Lawrence score was 3.1. There was no significant difference in pre-injection clinical scores in either group. There was a significant improvement of NPS on Day 1 and 14 in both injection groups(p<0.05). These improved pain scores were sustained at 6 weeks in both groups. WOMAC and Oxford Knee Scores showed a statistically significant improvement in the corticosteroid group. WOMAC scores showed significant improvement in the NSAID group, however these improvements didn't achieve statistical significance using the Oxford Knee Score. Corticosteroid or NSAID injectate are a safe and effective non-operative treatment strategy in the patient with knee osteoarthritis. Ketorolac appears to provide effective medium-term improvement of pain and clinical scores. Further follow-up is recommended to investigate if this trend in sustained

Introduction. We compared ultrasound guided methylprednizolone-lidacaine infiltrations around inflammatory area of plantar aponeurosis with systematic use of NSAID'S. Also, we investigated the reliability of the sonographic criteria (a. swelling of aponeurosis more than 20% in comparison to the healthy foot, b. effusion around aponeurosis, c. calcium deposits) most used to identify plantar fasciitis in clinically suspicious patients. Methods. A prospective randomised controlled clinical trial, including 28 patients (mean age: 47 years, range: 36–65 years, 85% females) with typical clinical symptoms of plantar fasciitis. All of these patients undertook a soft tissue ultrasonography of the plantar aponeurosis, without Doppler. Then, we randomly divided our sample in 2 groups, group A (14 patients) and group B (14 patients). In group A patients we performed an ultrasound guided injection –in transverse view- around the swollen part of aponeurosis, while we managed group B patients with per os NSAID's treatment (meloxicam 15 mg, once per day) for 2 weeks. Results. From the 28 suspicious patients we found 20 (71.4%) matching at least in one of our sonographic criteria. Swelling in comparison to the contralateral foot was the most usual found on these patients (14/20: 70% of the -ultrasound positive- patients). In group A patients the mean visual analogue scale (VAS) 100/100 after 1 month reduced –from 69/100 prior to injection- to 34/100, while 6 patients (42.85%) declared free of symptoms and 4 had poor or no improvement. In group B patients, the mean VAS decline was 21/100 (from 66/100 prior to injection, to 45/100 1 month later), but only 1 patient reported pain free. Conclusion. High frequency ultrasound of the foot is a good standing -but not excellent- diagnostic tool for plantar aponeurositis. Ultrasound guided methylprednisolone injections seems to have better short-term results than per os anti-inflammatory treatment on these patients

Background. Long-term glucocorticoid treatment increases incidence of osteoporotic or osteonecrotic disorders. Excessive bone loss and marrow fat accumulation are prominent features of glucocorticoid-induced osteoporosis. MicroRNA-29 (miR-29) family members reportedly modulate lineage commitment of stem cells. This study was undertaken to define the biological roles of miR-29a in skeletal and fat metabolism in the pathogenesis of glucocorticoid-induced osteoporosis. Methods. Osteoblast-specific miR-29a transgenic mice (Tg) driven by osteocalcin promoter (C57BL/6JNarl-TgOCN-mir29a) or wild-type (WT) mice were given methylprednisolone. Bone mass, trabecular and cortical bone microarchitecture were assessed by μCT. Comparative mRNA and protein expression was quantified by RT-PCR and immunoblotting. Primary bone-marrow mesenchymal cells were isolated for elucidating ex vivo osteogenic and adipogenic differentiation capacity. Results. Decremented miR-29a expression was associated with severe skeletal deterioration and excessive marrow adipogenesis in glucocorticoid-induced osteoporosis bone tissue. Tg mice had high bone mass, spacious trabecular bone and thick cortical bone microstructure. Tg mice also had modest responses to the deleterious actions of glucocorticoid on trabecular microstructure and histomorphological characteristics, mineral acquisition and attenuated marrow fat deposition and osteoclast resorption. Ex vivo, miR-29a overexpression promoted bone-marrow mesenchymal progenitor cells differentiation towards osteogenic cells and away from adipogenic lineage cells. Mechanistically, miR-29a via inhibiting histone deacetylase 4 (HDAC4) actions restored acetylation states of osteogenic regulators Runx2 and β-catenin and decreased osteoclastogenic factor RANKL and adipokine leptin expression in bone microenvironments. Conclusions. Glucocorticoid suppression of miR-29a disintegrates the homeostasis between osteogenic and adipogenic activities, thereby impairs bone formation and skeletal integrity. By suppressing HDAC4, miR-29a stabilizes Runx2 and β-catenin signalling that counteracts the adverse effects of glucocorticoid on bone mass and marrow adiposity. This study unveils the anabolic roles of miR-29a in the progression of glucocorticoid-induced bone loss. Sustained miR-29a action is beneficial for protecting against osteoporosis and excessive marrow adipogenesis. Level of evidence. I
