The goals of perioperative management are to relieve pain, achieve early mobilization after surgery, reduce length of hospital stay, and obtain adequate patient satisfaction. Several treatment options combining systemic analgesics and/or regional analgesia with or without opioids are available for postoperative pain; however, a gold standard has not been established although there is a progressive shift towards multimodal approaches to improve analgesia while minimizing opioid-related side effects.

EX-TRA-05 (DAVID-ART) was a randomised, double-blind, parallel, pivotal study, evaluating the analgesic efficacy and safety of the innovative oral combination of dexketoprofen/tramadol 25mg/75mg in comparison with the individual components (tramadol given at the higher dose of 100mg) on moderate to severe acute pain after total hip replacement. Repeated doses of study drug were administered every 8 hours and pain intensity (PI) was to be scored according to a 100mm visual analogue scale (VAS) on a programmed e-diary every 2 hours over a 56-hour period (i.e. along 7 repeated doses). A placebo arm was included at the first administration to validate the pain model. Rescue medication, metamizole 500mg, was available during the treatment period. The study primary endpoint was the mean sum of the pain intensity difference values throughout the first 8 hours (SPID₈), which considered the 3 active treatment arms and placebo (ITT population; N=641). In this phase, a clear superiority of the combination over the single agents was demonstrated (p<0.05). An additional analysis was performed during the entire 0–56h repeated-dose period excluding those patients who had received placebo at the first dose (N=161). The estimated mean (SE) differences on PI-VAS over 24, 32 and 56 hours post first dose (0–24h, 0–32h, and 0–56h) between the combination and each single agent were evaluated.

Patients who received active analgesic from the first dose (mITT population; N=480) were aged 29–80 years (42% were ≥65 years). At randomisation, pain was moderate (≥40–60mm) in 51% patients and severe (>60mm) in 49%. For dexketoprofen/tramadol, mean (SD) PI-VAS values were 22 (4.0) over 24 hours; 21 (4.1) over 32 hours; and 19 (3.8) over 56 hours. The estimated differences versus dexketoprofen 25mg and tramadol 100mg were respectively 10 (0.7) and 7.6 (0.7) over 24 hours; 9.8 (0.6) and 7.2 (0.6) over 32 hours; and 8.1 (0.5) and 6.3 (0.5) over 56 hours (p<0.0001 for all comparisons), which confirmed the superiority of the combination versus both single agents throughout the periods analysed.

This significant higher decrease of PI favouring dexketoprofen/tramadol 25mg/75mg over dexketoprofen 25mg and tramadol 100mg, all given every 8 hours, during the first 56 hours post dose confirmed the superior analgesia shown after the first 0–8h post-dose period. The combination of dexketoprofen/tramadol 25mg/75mg is able to provide a level of analgesia above that achievable by each component alone, with a sustained effect when used as a multiple-dose regimen. The addition of this new combo to the analgesic armamentarium may contribute to facilitate early mobilization after surgery, thus positively impacting perioperative co-morbidities and length of in-hospital stay.

The Ionising Radiation (Medical Exposure) Regulations 2000 is concerned with: “the making of safety measures in regard to radioactive substances and the emission of ionising radiation”. Responsibility is placed upon the Practitioner, Operator, Referrer and employer. A clinical evaluation of the outcome of each medical exposure must be recorded.” In Ayr Hospital Radiologist report A&E radiographs but not those in fracture clinic unless a specific request was made. Therefore the Surgeon/Trainee must record their interpretation.

An audit was completed to review the rate of documentation of the interpretation of radiographs in the clinical records of consecutive patients attending fracture clinics Notes and radiographs were reviewed from 6 separate fracture clinics. 106 patients attended during the time period and were seen by 9 different surgeons; 5 consultants and 4 training grade surgeons. 46 out of 106 patients were x-rayed and interpretation recorded in 38 cases. No interpretation was found in 8 cases, giving an overall compliance of 82.6% with no difference between different grades of surgeon: Consultants 79.2% (19/24); Trainees 86.4% (19/22).

These finding were presented at a departmental audit meeting and the audit loop was then closed by a second period of audit with an improvement in the consultants compliance to 100% (22/22) p=0.05 and no significant change in the trainees performance 75% (18/24).

Introduction

With an ageing population comes an increased prevalence of osteoporosis and associated fracture. Whilst treatment of the condition following such a fracture is partially effective, primary prevention through screening and appropriate follow-up is the ideal. In order to assess a population's risk of fracture, paper questionnaires would traditionally have to be sent, however this is an wasteful and costly. A more efficient method may be to have patients assess their own FRAX score through a modified computer application.

The aim of this study was to perform a systematic review of the literature on Gustilo-Anderson (GA) type IIIB open tibial shaft (AO-42) injuries to determine the consistency of reporting in the literature. A search of PubMed, EMBASE and Cochrane Central Register of Controlled Trials was performed to identify relevant studies published from January 2000 to January 2021 using the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement. The study was registered using the PROSPERO International prospective register of systematic reviews. Patient/injury demographics, management and outcome reporting were recorded. There were 32 studies that met the inclusion criteria with a total of 1,947 patients (70.3% male, 29.7% female). There were 6 studies (18.8%) studies that reported on comorbidities and smoking, with mechanism of injury reported in 22 (68.8%). No studies reported on all operative criteria included, with only three studies (9.4%) reporting for time to antibiotics, 14 studies (43.8%) for time from injury to debridement and nine studies (28.1%) for time to definitive fixation. All studies reported on the rate of deep infection, with a high proportion documenting union rate (26/32, 81.3%). However, only two studies reported on mortality or on other post-operative complications (2/32, 6.3%). Only 12 studies (37.5%) provided any patient reported outcomes. This study has demonstrated a deficiency and a lack of standardized variable and outcome reporting in the orthopaedic literature for Gustilo-Anderson type IIIB open tibial shaft fractures. We propose a future international collaborative Delphi process is needed to standardize

Introduction. Despite the implementation of numerous preventive measures in recent years, the persistent challenge of periprosthetic infections remains. Among the various strategies, metallic modification of implants, particularly with silver, has emerged as a promising avenue. Silver's antimicrobial properties, coupled with its low human toxicity, render it an appealing option. However, ongoing debate surrounds its comparative efficacy in infection prevention when contrasted with titanium-coated prostheses. Methods. The PubMed database was systematically searched up to March 2024. Studies in English that met predetermined inclusion/exclusion criteria and utilized “Megaprosthesis AND infection” and “ silver-coated AND infection “ as key terms were included. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA) statement guided the article selection process. Results. From a pool of 1892 potential papers after literature screening, 11 studies with a total of 1419 patients were meticulously selected for analysis. Among these patients, 638 were treated with silver-coated implants, while 781 received titanium-coated implants, resulting in 166 recorded cases of infection. Remarkably, the infection rate stood at 9.2% for the silver-coated group, contrasting with 13.4% for the titanium-coated group. The subsequent analysis unveiled a notable discrepancy in proportions (P difference = -0.0473, 95%CI: -0.088 to -0.006), signaling a statistically significant decrease in infections within the silver-coated cohort. Furthermore, the I2 statistic, denoting heterogeneity in effect sizes, stood at 21.8% (95%CI: 0.0-66.9), indicating a modest degree of variability among the studies. Conclusion. In conclusion, our systematic review and meta-analysis shed light on the potential of silver-coated implants in mitigating periprosthetic infections. Despite the persistent challenge posed by such infections, our findings suggest a statistically significant decrease in infection rates among patients treated with silver-coated implants compared to those with titanium-coated ones

Applications of weightbearing computed tomography (WBCT) imaging in the foot and ankle have emerged over the past decade. However, the potential diagnostic benefits are scattered across the literature, and a concise overview is currently lacking. Therefore, we aimed to systematically review all reported diagnostic applications per anatomical region in the foot and ankle. A systematic literature search was performed in the electronic databases PubMed, EMBASE, Cochrane Library, and Web of Science. Search terms consisted of “weightbearing/standing CT and ankle, hind-, mid- or forefoot”. English language studies analyzing the diagnostic applications of WBCT were included. Studies were excluded if they simulated weightbearing CT, described normal subjects, included cadaveric samples or samples were case reports. The modified Methodological Index for Non-Randomized Studies (MINORS) was applied for quality assessment. The added value was defined as the review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines and registered in the Prospero database (CRD42019106980). A total of 48 studies (prospective N=8, retrospective N=36, cohort study N=1, diagnostic N=2, prognostic comparative study N=1) were found to be eligible for review. The following diagnostic applications were identified per anatomical area in the foot: ankle (osteoarthritis N=5, ligament injury N=6); hindfoot (deformity N=9); midfoot (Lisfranc injury N=2, flatfoot deformity N=13, osteoarthritis N=1); forefoot (hallux valgus N=12). The identified studies contained diagnostic applications that could not be used on plain radiographs. The mean MINORS equaled 10.1 on a total of 16 (range: 8 to 12). Diagnostic applications of weightbearing CT imaging are most frequently studied in hindfoot deformity, but other area's areas are on the rise. Post-processing of images was identified as the main added value compared to WBRX. However, the findings should be interpreted with caution as the average quality score was moderate. Therefore, future prospective studies are warranted to consolidate the role of WBCT in diagnostic and therapeutic algorithms

Abstract. Objective. There is no specific framework for the clinical management of sports related brachial plexus injuries. Necessarily, rehabilitation is based on injury presentation and clinical diagnostics but it is unclear what the underlying evidence base to inform rehabilitative management. Methods. A systematic review of the literature was undertaken in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We applied the PEO criteria to inform our search strategy to find articles that reported the rehabilitative management of brachial plexus injuries sustained while playing contact sports. An electronic search of Medline, CINAHL, SPORTDiscus and Web of Science from inception to 3rd November 2022 was conducted. MESH terms and Boolean operators were employed. We applied an English language restriction but no other filters. Manual searches of Google Scholar and citation searching of included manuscripts were also completed. All study types were considered for inclusion provided they were published as peer-reviewed primary research articles and contained relevant information. Two investigators independently carried out the searches, screened by title, abstract and full text. Two researchers independently extracted the data from included articles. Data was cross-checked by a third researcher to ensure consistency. To assess internal validity and risk of bias, the Joanna Briggs Institute (JBI) critical appraisal tools were utilised. Results. The search generated 88 articles. Following removal of duplicates, 43 papers were evaluated against the eligibility criteria. Nine were eligible for full text review, with the majority of exclusions being expert opinion articles. Eight case reports were included. One article reported three individuals, resulting in data for ten athletes. The mean age was 19.8 years (±4.09). Injuries occurred in five American football players, two wrestlers, two rugby players, and a basketball player. No two studies applied the same diagnostic terminology and the severity of injury varied widely. Burning pain and altered sensation was the most commonly reported symptom, alongside motor weakness in the upper limb. Clinical presentation and management differed by injury pattern. Traction injuries caused biceps motor weakness and atrophy of the deltoid region, whereas compression injuries led to rotator cuff weakness. In all cases treatment was separated into acute and rehabilitative management phases, however the time frames related to these differed. Acute interventions varied but essentially entailed soft tissue inflammation management. Rehabilitation approaches variously included strengthening of shoulder complex and cervical musculature. Return-to-play criteria was opaque. The methodological quality of the case reports was acceptable. Four met all nine of the JBI evaluation criteria, and a further three met at least 75% of items. Conclusion(s). There is a distinct lack of evidence supporting rehabilitation management of sports related brachial plexus injury. Through systematic review we found only eight reports, representing ten individual case studies. No trials, cohort studies, or even retrospective registry-based studies are available to inform clinical management, which, necessarily, is driven by expert opinion and application of basic rehabilitation principles.

Introduction and Objective. Several studies have described double and triple femoral neck lengthening osteotomies to correct coxa brevis deformity, however, no overview exists in literature. Our aim was to perform the first systematic review of the outcomes of double and triple femoral neck lengthening. Materials and Methods. After an extensive search in Pubmed, CINAHL and Embase libraries for published articles using the following search strategy: ‘(((proximal femoral deformity) OR hip dysplasia) OR coxa brevis) AND (((femoral neck lengthening) OR double proximal femoral osteotomy) OR triple proximal femoral osteotomy)’, we included studies reporting the results of double and triple femoral neck osteotomies. Clinical and radiological outcomes, and reported complications were extracted. The review process was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Results. After evaluating 456 articles, we included 11 articles reporting 149 osteotomies in 143 patients (31% male, 64% female, 5% unspecified). Mean age of the patients was 20 years (range 7 years to 52 years). Indications were developmental hip dysplasia (51%), Perthes disease (27%), infection (6%), post-trauma (4%), congenital disorders (2%), slipped capital femoral epiphysis (1%), idiopathic (3%) and unknown (6%). The mean limb length discrepancy reduced by 12 mm (0 mm to 40 mm). In total, 65% of 101 positive Trendelenburg sign hips experienced improvement of abductor muscle strength. An 18% (9% to 36%) increase could be found in functional hip scores. Mean increase in articulo-trochanteric distance was 24 mm (10 mm to 34 mm). Five patients older than 30 years at the time of osteotomy and two younger patients with prior hip incongruency had disappointing results and required arthroplasty. In all, 12 complications occurred in 128 osteotomies, in which complications were reported. Conclusions. This first systematic review of double and triple femoral neck lengthening osteotomies shows that favorable outcomes and few complications can be expected in coxa brevis, however, excessive caution is required in older patients with incongruent hips

Introduction and Objective. Nonunion is incomplete healing of fracture and fracture that lacks potential to heal without further intervention. Nonunion commonly presents with persistent pain, swelling, or instability. Those symptoms affect patient quality of life. It is known that using low intensity pulsed ultrasound (LIPUS) for fresh fractures promotes healing. However, effectiveness of LIPUS for nonunion is still controversial. If LIPUS is prove to be effective for healing nonunion, it can potentially provide an alternative to surgery. In addition, we can reduce costs by treating nonunion with LIPUS than performing revision surgery. Materials and Methods. The two authors carried out a systematic search of PubMed, Ovid MEDLINE, and the Cochrane Library. Meta-analysis of healing rate in nonunion and delayed union patients who underwent LIPUS was conducted based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) instruction method using a random effects model. Results. The initial search identified 652 articles. Of these, 541 were excluded on the basis of the title because they were either a review paper or covered an unrelated topic. The abstracts of the remaining 111 articles were examined further. That review resulted in a sample of 12 articles. We performed a meta-analysis with a random effects model using Open Meta Analyst software. The result of pooled effect size of healing rate was 73.4% (95%CI: 65.3–81.6%). Due to the fact that nonunion lacks potential to heal without further intervention, we suggest that the therapeutic effect of 73.4% from LIPUS is sufficiently effective. As far as we know, there are no trials comparing the therapeutic effectiveness of surgery and LIPUS, so it cannot be said which is more advantageous. However, the healing rate of revision surgery was reported between 68–96%; therefore, our result is within that range. Thus, if surgery is difficult due to complications, we can recommend LIPUS. Conclusions. Meta-analysis of healing rate of nonunion treated by low-intensity pulsed ultrasound is 73.4%, which suggests sufficient therapeutic effectiveness. Furthermore, we can say that LIPUS may provide an alternative treatment for nonunion patients who cannot tolerate revision surgery due to complications

The purpose of this investigation was to evaluate systematically the literature concerning biopsy, MRI signal to noise quotient (SNQ) and clinical outcomes in graft-maturity assessment after autograft anterior cruciate ligament reconstruction (ACLR) and their possible relationships. Methods: The systematic review was reported and conducted according to the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines. Studies through May 2019 evaluating methods of intra-articular ACL autograft maturity assessment were considered for inclusion. Eligible methods were histologic studies of biopsy specimens and conventional MRI studies reporting serial SNQ and/ or correlation with clinical parameters. Ten biopsy studies and 13 imaging studies, with a total of 706 patients, met the inclusion criteria. Biopsy studies show that graft remodeling undergoes an early healing phase, a phase of remodeling or proliferation and a ligamentization phase as an ongoing process even 1 year after surgery. Imaging studies showed an initial increase in SNQ, peaking at approximately 6 months, followed by a gradual decrease over time. There is no evident correlation between graft SNQ and knee stability outcome scores at the short- and long-term follow-up after ACLR. The remodeling of the graft is an ongoing process even 1 year after ACLR, based on human biopsy studies. MRI SNQ peaked at approximately 6 months, followed by a gradual decrease over time. Heterogeneity of the MRI methods and technical restrictions used in the current literature limit prediction of graft maturity and clinical and functional outcome measures by means of MRI graft SNQ after ACLR

Abstract. Objective. Articular cartilage damaged through trauma or disease has a limited ability to repair. Untreated, these focal lesions progress to generalized changes including osteoarthritis. Musculoskeletal disorders including osteoarthritis are the most significant contributor to disability globally. There is increasing interest in the use of mesenchymal stem cells (MSCs) for the treatment of focal chondral lesions. There is some evidence to suggest that the tissue type from which MSCs are harvested play a role in determining their ability to regenerate cartilage in vitro and in vivo. In humans, MSCs derived from synovial tissue may have superior chondrogenic potential. Methods. We carried out a systematic literature review on the effectiveness of synovium-derived MSCs (sMSCs) in cartilage regeneration in in vivo studies in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. Nineteen studies were included in our review; four examined the use of human sMSCs and the remainder were conducted using sMSCs harvested from animals. Results. Despite the variability of animals, cell harvesting techniques, methods of delivery, and outcome measures, all studies reported successful cartilage repair with sMSC transplantation. Conclusion. We conclude that sMSC transplantation holds promise as a treatment option for focal cartilage defects. We believe that defining the cell population being used, establishing standardized methods for MSC delivery, and the use of objective outcome measures should enable future high-quality studies such as randomized controlled clinical trials to provide the evidence needed to manage chondral lesions optimally.

Objectives. Our objective was to perform a systematic review of the literature and conduct a meta- analysis to investigate the effect of initial varus or valgus displacement of proximal humerus on the outcomes of patients with proximal humerus fractures treated with open reduction and internal fixation. Methods. In accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement standards, we performed a systematic review. Electronic databases MEDLINE, EMBASE, CINAHL and the Cochrane Central Register of Controlled Trials (CENTRAL) were searched to identify randomised and non-randomised studies comparing postoperative outcomes associated with initial varus versus initial valgus displacement of proximal humerus fracture. The Newcastle–Ottawa scale was used to assess the methodological quality and risk of bias of the selected studies. Fixed-effect or random-effects models were applied to calculate pooled outcome data. Results. We identified two retrospective cohort studies and one retrospective analysis of a prospective database, enrolling a total of 243 patients with proximal humerus fractures. Our analysis showed that initial varus displacement was associated with a higher risk of overall complication (RR 2.28, 95% CI 1.12–4.64, P = 0.02), screw penetration (RR 2.30, 95% CI 1.06–5.02, P = 0.04), varus displacement (RR 4.38, 95% CI 2.22–8.65, P < 0.0001), and reoperation (RR 3.01, 95% CI 1.80–5.03, P < 0.0001) compared to valgus displacement. There was no significant difference in avascular necrosis (RR 1.43, 95% CI 0.62–3.27, P = 0.40), infection (RR 1.49, 95% CI 0.46–4.84, P = 0.51), and non-union or malunion (RR 1.37, 95% CI 0.37–5.04, P = 0.64). Conclusions. The best available evidence demonstrates that initial varus displacement of proximal humerus fractures is associated with higher risk of overall complication, screw penetration, varus displacement, and reoperation compared to initial valgus displacement. The best available evidence is not adequately robust to make definitive conclusions. Further high quality studies, that are adequately powered, are required to investigate the outcomes of initial varus and valgus displacement in specific fracture types

Objectives. Our objective was to perform a systematic review of the literature and conduct a meta-analysis to investigate the outcomes of open versus arthroscopic methods of ankle fusion. Methods. In accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement standards, we performed a systematic review. Electronic databases MEDLINE, EMBASE, CINAHL and the Cochrane Central Register of Controlled Trials (CENTRAL) were searched to identify randomised and non-randomised studies comparing outcomes of arthroscopic and open ankle arthrodesis. The Newcastle-Ottawa scale was used to assess the methodological quality and risk of bias of the selected studies. Fixed-effect or random-effects models were applied to calculate pooled outcome data. Results. We identified one prospective cohort study and 5 retrospective cohort studies, enrolling a total of 286 patients with ankle arthritis. Our analysis showed that open ankle fusion was associated with a lower fusion rate (OR 0.26, 95% CI 0.13–0.52, P = 0.0002), longer tourniquet time (MD 16.49, 95% CI 9.46–23.41, P<0.00001), and longer length of stay (MD 1.60,95% CI 1.10–2.10, P<0.00001) compared to arthroscopic ankle fusion; however, there was no significant difference between two groups in terms of infection rate (OR 2.41, 95% CI 0.76–7.64, P = 0.14), overall complication rate (OR: 1.54, 95% CI 0.80–2.96, P = 0.20), and operation time (MD 4.09, 95% CI −2.49–10.66, P = 0.22). The between-study heterogeneity was high for tourniquet time but low or moderate for other outcomes. The direction of the effect sizes remains unchanged throughout sensitivity analyses. Conclusions. The best available evidence demonstrates that arthroscopic ankle fusion may be associated with a higher fusion rate, shorter tourniquet time, and shorter length of stay compared to open ankle fusion. We found no significant difference between two groups in terms of infection rate, overall complication rate, and operation time. The best available evidence is not adequately robust to make definitive conclusions. Long-term results of the comparative efficacy of arthroscopic ankle fusion over open ankle fusion are not currently available. Further high quality randomised controlled trials that are adequately powered are required

Objectives

Degenerative disc disease (DDD) and osteoarthritis (OA) are relatively frequent causes of disability amongst the elderly; they constitute serious socioeconomic costs and significantly impair quality of life. Previous studies to date have found that aggrecan variable number of tandem repeats (VNTR) contributes both to DDD and OA. However, current data are not consistent across studies. The purpose of this study was to evaluate systematically the relationship between aggrecan VNTR, and DDD and/or OA.

Objectives

This study reports on a secondary exploratory analysis of the early clinical outcomes of a randomised clinical trial comparing robotic arm-assisted unicompartmental knee arthroplasty (UKA) for medial compartment osteoarthritis of the knee with manual UKA performed using traditional surgical jigs. This follows reporting of the primary outcomes of implant accuracy and gait analysis that showed significant advantages in the robotic arm-assisted group.

Objectives

Microindentation has the potential to measure the stiffness of an individual patient’s bone. Bone stiffness plays a crucial role in the press-fit stability of orthopaedic implants. Arming surgeons with accurate bone stiffness information may reduce surgical complications including periprosthetic fractures. The question addressed with this systematic review is whether microindentation can accurately measure cortical bone stiffness.

Objectives

The aim of this study was to systematically review the literature on measurement of muscle strength in patients with femoroacetabular impingement (FAI) and other pathologies and to suggest guidelines to standardise protocols for future research in the field.

Objectives

Lengthening osteotomies of the calcaneus in children are in general grafted with bone from the iliac crest. Artificial bone grafts have been introduced, however, their structural and clinical durability has not been documented. Radiostereometric analysis (RSA) is a very accurate and precise method for measurements of rigid body movements including the evaluation of joint implant and fracture stability, however, RSA has not previously been used in clinical studies of calcaneal osteotomies. We assessed the precision of RSA as a measurement tool in a lateral calcaneal lengthening osteotomy (LCLO).
