Objective: Given the bone sensitivity to mechanical stimulus, bone-loading exercises and applying the Pulsed Electromagnetic Fields (PEMF(s)) are recommended for promoting bone strength. In this context, these two interventions 's effect on bone turnover markers (BTMs) in osteoporosis patients is yet to be clarified; consequently, an attempt is made in this study to compare the effect of these two interventions on bone turnover markers in women with Postmenopausal Osteoporosis (PMOP).

Methods: This study is design as a randomized, single-center, three-arms, controlled trial. A total of 51 women with PMOP will be randomly assigned to three groups of 17, using opaque, sealed envelopes containing labels for A, B, and C groups. Group A) will receive bone-loading exercises, B) will follow the PEMF(s) and C) will be exposed to the combination of A and B. These three groups will require intervention for 24 sessions (2 sessions/week) next to their routine medical treatment (Alendronate+ Calcium+ Vitamin D). The primary outcome of this study is the serum biomarker of bone formation (bone-specific alkaline phosphatase, BSALP) and resorption (N-terminal telopeptide, NTX). The secondary outcomes consist of thoracic kyphosis angle, fear of falling, and quality of life. The outcomes are measured three times: at baseline, after 24 sessions of intervention, and at 12 weeks follow-up. A primary outcome will be measured and reported by a laboratory expert who is blinded to the participant grouping.

Result: The trial has the code of ethics for research (IR.TUMS.FNM.REC.1401.126) and the code of Iranian Registry of Clinical Trials (IRCT) (IRCT20221202056687N1). Study results are expected to be available by mid-2024.

Conclusion: This trial will provide new practical knowledge on the bone-loading exercises and PEMFS(s)'s effect on PMOP women. This knowledge is of the essence for physiotherapists, clinicians, other healthcare professionals, and policymakers in the healthcare system.

Second-generation large-diameter head hip resurfacing (HR) arthroplasty has gained popularity in terms of its potential for minimal wear and the preservation of proximal femoral bone stock. HR faces challenges, such as increased hip fracture rates and adverse reactions to metal detritus, despite the fact that over one million metal-on-metal (MoM) arthroplasties have been performed globally. FDA issued warnings in 2011 and 2016 regarding higher failure rates in women and categorized MoM implants as high-risk, influencing U.S. surgeons to limit HR in women. Conversely, European and Australian registries report 6.4% to 54.4% of HR procedures are performed on women. Addressing concerns via targeted follow-ups and age-specific recommendations can help provide equitable access to advanced medical treatments.

Posterior shoulder instability (PSI) is a shoulder pathology that is challenging to diagnose, leading to treatment delay and exacerbation of symptoms. Etiology can be both traumatic and atraumatic, and a comprehensive clinical history plays a significant role in achieving diagnosis. Imaging in the setting of PSI can reveal a reverse-Bankart lesion, a reverse Hill-Sachs lesion, posterior labral cysts, and potentially glenoid or lesser tuberosity fractures. Both conservative and surgical options exist for patients with PSI, and management often depends on case severity, extent of bone loss, and patient goals and expectations. Holistic patient education regarding the etiologies, mechanisms and possible treatment options available is pivotal for achieving high levels of patient satisfaction and optimal outcomes.

Flail foot is a condition characterized by a significant weakness in ankle dorsiflexion, resulting in limited or no active mobility in the ankle. To address this issue, we described a novel approach called tenodesis, which has been developed for ankle joint stabilization. This technique utilizes the patient's tendons to minimize potential complications. The primary focus of this method is to preserve ankle passive dorsiflexion, thereby maintaining the foot in a neutral position, helping prevent foot drop, reducing the risk of neuropathic ulcers, and keeping joint proprioception. Furthermore, maintaining passive ankle dorsiflexion is particularly important in societies where activities such as squatting are integral to daily life. The study aims to introduce a new surgical technique for flail foot.

Objectives: To compile the existing literature on bilateral anterior shoulder dislocation (BASD) and analyze patient demographics, mechanisms of injury, injury characteristics, management, and outcome.

Methods: This systematic review was conducted in accordance with Preferred Reporting Items for Systematic review and Meta-Analyses (PRISMA) guidelines. Online databases, including Ovid Medline 1946-, Embase.com 1947-, Scopus 1960-, Cochrane Central, and Clinicaltrials.gov were systematically queried. Studies eligible for inclusion were case reports or case-series, documenting BASD. Two reviewers independently screened and applied a set of a priori exclusion criteria to each returned study. Data were extracted, compiled, and synthesized from each reported case of BASD. Contingency tables/Chi-Square Analyses, T-tests, and univariate regression analyses were conducted to assess relationships between different variables.

Results: Eighty-one studies (87 cases of BASD) were included. Patients were 41.1 (SD± 19.5) years old and most were male (n=63; 72.4%). Around a quarter of patients (28.7%) had a history of epilepsy/seizures or were being worked-up for such. Younger males were more likely to have BASD due to a seizure or electrocution (P<0.05). Close to a third of cases (n=27; 31.0%) were delayed in presentation. Those sustaining seizures or electrocutions were more likely to be delayed in presentation (P=0.013). Most events resulted in simple dislocations that were closed reduced successfully. BASD resulting from seizures or electrocutions were more likely to be fracture-dislocations (P=0.018); and in younger patients with fracture-dislocations, closed reduction was more often to fail or not be attempted (P<0.05). Median follow-up was 6 months (IQR: 3 months - 12 months). Seven patients (10.6%) had complications and 4 (2.3%) demonstrated recurrent instability.

Conclusion: In young males presenting with BASD without known trauma, suspicion should be high for a convulsant event. In patients with a known seizure disorder who present with chronic bilateral shoulder or arm pain, BASD should be considered and work-up should be expedited to avoid misdiagnosis.

Objectives: This meta-analysis was conducted to study the hemostatic efficacy of bone wax in total joint arthroplasty (TJA) defined in this manuscript as total knee arthroplasty and total hip arthroplasty.

Methods: PubMed, Embase, Google Scholar (page 1-20), and Scopus were searched updated to November 2023. Only comparative studies were included. The clinical outcomes evaluated were the transfusion rate, total blood loss, and the loss of hemoglobin on day 1, 3, and 5 post-operatively.

Results: Only 3 studies met the inclusion criteria and were included in this meta-analysis. Bone wax was associated with a reduced transfusion rate (p=0.01), reduced total blood loss (p=0.001), and a decrease in hemoglobin loss on day 1 (p<0.00001), day 3 (p<0.0001), and day 5 (p<0.00001) after the surgery.

Conclusion: Bone wax reduced the rate of transfusion, total blood loss, and hemoglobin loss after the surgery. This may induce a reduction the cost of correcting post-operative anemia as well as decrease hospital stay and improving functional outcomes in patients undergoing TJA. Better-conducted randomized controlled studies and cost-effectivity studies could strengthen these findings.

Numerous surgical techniques have been developed to address recurrent anterior shoulder instability, with the Bankart repair and the Latarjet procedure emerging as dominant. With recent advancements in keyhole surgery, there's been a surge in popularity for all-arthroscopic procedures. Our systematic review aims to determine if there's justification for incorporating these techniques into a classification system for guiding treatment of traumatic anterior recurrent instability. We identified and analysed a variety of key studies, including 12 systematic reviews, three prospective studies, seven non-randomized prospective and retrospective studies, along with one biomechanical study. Our study sheds light on the wide range of procedures available to shoulder surgeons dealing with traumatic anterior recurrent instability. We introduce a novel classification system (BoTH) designed to simplify the decision-making process in this context.

Objectives: To compare the radiological outcomes after fixation of distal tibia fractures with IM nail between patients in whom poller screw was used vs those in whom it was not used.

Methods: A retrospective cohort study was conducted between 1st January 2009 to 31st June 2019 including patients treated with IM nail for distal tibial metaphyseal fractures. Patients were divided into 2 groups based on whether a poller screw was placed during surgery or not. The exposed group consisted of patients who underwent augmentation of IM nail with a poller screw, while control group included patients who underwent fixation with nail alone. All adult patients aged ≥18 years were included and patients with pathological fractures, known metabolic bone disease were excluded from the study. Follow-up x-rays were viewed through our hospital database and fracture healing was classified as either union, malunion or non-union based on radiographic parameters. A Radiographic Union Score in Tibia (RUST) score was calculated and a score of ≥9 was considered conclusive for complete union.

Results: 93 patients were included in the study with 21 patients in the exposed and 72 in the control group. According to the analysis, there were no significant differences in baseline characteristics of the study participants. The exposed group was found to be associated with increased rates of union and decreased non-union and mal-union rates compared to control group (P-value = 0.003). Mean RUST score was also noted to be significantly higher in exposed group compared to control group with a P-value of 0.025.

Conclusion: Use of poller screw with IM nail in treatment of distal tibial fractures is important in improving post-operative outcomes and decreasing mal-union and non-union.

Objectives: This meta-analysis studies and assesses the pain relief effect of different pre-operative traction systems in proximal and femoral shaft fractures as this subject is still debated and no clear guidelines are established.

Methods: PubMed, Cochrane, Embase and Google Scholar (page 1-20) were searched until January 2024. The clinical outcomes collected consisted of pain scales following traction.

Results: Two randomized clinical trials were included to compare skeletal (72 patients) to skin traction (80 patients) and eight randomized clinical trials with one prospective study were included to compare traction (457 patients) versus no traction (439 patients). Our results revealed no differences in terms of post-operative pain VAS between both the skeletal and skin traction as well as between traction and no traction.

Conclusion: No added benefit of traction was observed when pain relief is the main consideration. Furthermore, with their different potential complications, systematic pre-operative traction should not be implemented in all femoral fractures.

Objectives: The ideal timing for patients undergoing bilateral total knee arthroplasty (TKA) remains unknown. The purpose of this study was to compare 90-day outcomes between unilateral, simultaneous bilateral, and staged bilateral TKA.

Methods: The PearlDiver database was used to retrospectively identify 231,119 patients undergoing primary TKA during 2015-2020, of which 67,956 (29.4%) were bilateral. Bilateral TKA patients were divided into cohorts of simultaneous bilateral TKA and staged bilateral TKA at 1-14 days, 15-30 days, 31-90 days, and 91-365 days. Each bilateral TKA cohort underwent one-to-one matching with unilateral TKA patients based on age, gender, year, Elixhauser Comorbidity Index (ECI), and a history of obesity, diabetes, and tobacco use. Ninety-day outcomes were compared between matched groups via univariate and multivariate analysis. In staged bilateral TKA groups, outcomes were collected beginning after the second TKA.

Results: Compared to unilateral TKA, simultaneous bilateral TKA was associated with higher rates of venous thromboembolism (VTE; odds ratio [OR] 1.28, 95% confidence interval [CI] 1.07-1.54, p=0.007), acute kidney injury (AKI; OR 1.47, CI 1.17-1.84, p=0.001), blood transfusion (OR 6.81, CI 5.43-8.65, p<0.001), and any complication (OR 1.63, CI 1.49-1.78, p<0.001). Staged bilateral TKA at any time interval studied was associated with a similar or decreased risk of individual complications, emergency department visits, readmissions, reoperations, and any complication relative to unilateral TKA.

Conclusion: Simultaneous bilateral TKA is associated with an increased risk of adverse events compared to unilateral TKA. However, bilateral TKA staged at a short interval appears safe in appropriately selected patients.
